FAQFrequently Asked Questions

• Q1: Can Molex 0901310932 be used with a standard 2.54 mm dual-row cable connector? A1: Molex 0901310932 is a 24-position, two-row header with 2.54 mm pitch and 2.54 mm row spacing, so it can mate with a compatible 0.100-inch dual-row female connector. The mating housing must match the 24-position layout, pin dimensions, contact engagement, and polarization requirements because 0901310932 is an unshrouded header without an integral keying feature.
• Q2: What PCB footprint and drilling pattern should I use for Molex 0901310932? A2: The PCB footprint for Molex 0901310932 should use two parallel rows of 12 plated through-holes on 2.54 mm centers. The final hole diameter and pad geometry should be selected from the mating contact, solder-process, and PCB fabrication requirements because the available product information does not specify a recommended finished hole size. Confirm the body outline and clearance around the 0901310932 solder tails before releasing the board.
• Q3: Is Molex 0901310932 suitable for a vibration-prone automotive control unit? A3: Molex 0901310932 is listed for automotive and general-purpose applications, but it is an unshrouded push-pull header with no stated operating-temperature, ingress-protection, current-rating, or voltage-rating values in the supplied data. For a vibration-prone automotive assembly, evaluate cable retention, solder-joint fatigue, connector support, contact fretting, environmental sealing, and the mating connector as a complete system. A locking or shrouded connector may be better suited where positive retention and protection from contamination are required.
• Q4: Can I use Molex 0901310932 for power distribution between a PCB and a wire harness? A4: Molex 0901310932 can provide a board-to-wire interface, but the supplied specifications do not state a current rating or voltage rating. Do not assign a power budget to 0901310932 from the 2.54 mm pitch alone. Determine allowable current from the mating contact system, conductor size, temperature rise, PCB copper, solder joints, and derating requirements, then verify creepage, clearance, and touch-protection requirements for the intended voltage.
• Q5: Does Molex 0901310932 provide reverse-polarity or mis-mating protection? A5: Molex 0901310932 is an unshrouded header, so the part itself does not provide a keyed or shrouded mating interface. A design using 0901310932 should add polarity control through the mating housing, an asymmetric pin assignment, a separate mechanical key, connector orientation, or assembly controls. For field-serviceable equipment, an unkeyed 0901310932 interface can allow offset or reversed mating unless the surrounding design prevents it.
• Q6: Can Molex 0901310932 be cut into smaller sections for a custom pin count? A6: Molex 0901310932 is identified as a breakaway header, which may allow separation into shorter sections when the manufacturer’s breakaway procedure and mechanical limits support it. After separating 0901310932, inspect the cut end for damaged insulation, exposed metal, burrs, and reduced mechanical support. The resulting section should be verified for PCB fit, mating alignment, solderability, and the required creepage and clearance distances.
• Q7: Is Molex 0901310932 a direct replacement for TE Connectivity 4-103240-0 or 4-102977-0-12? A7: Molex 0901310932 may be considered alongside TE Connectivity 4-103240-0 and 4-102977-0-12 because the listed alternatives are associated with similar 2.54 mm header applications, but they should not be treated as automatic drop-in replacements. Compare position count, row spacing, pin dimensions, contact plating, post length, body height, solder-tail geometry, mating compatibility, and availability. The 0901310932 part has 24 positions, gold-plated mating contacts, tin-plated posts, 6.75 mm mating contact length, and 2.90 mm post length; any difference can affect the PCB footprint or mating engagement.
• Q8: How does Molex 0901310932 compare with Wurth Elektronik 61302421121 or Harwin M20-9721245 for a redesign? A8: Molex 0901310932, Wurth Elektronik 61302421121, and Harwin M20-9721245 should be compared by the complete interconnect system rather than pitch alone. Check whether the alternate has the same 24-position, two-row arrangement, unshrouded or shrouded construction, pin size, mating length, PCB tail length, contact finish, insulator height, and retention method. A part with a different housing height or post length can alter cable clearance, board stacking, soldering, and mating force even when its nominal pitch matches 0901310932.
• Q9: What contact and solder-process limits should I verify before using Molex 0901310932 in production? A9: Molex 0901310932 uses brass square contacts with gold mating finish and tin posts intended for through-hole solder termination. The supplied information does not define solder-wave, selective-solder, hand-solder, or rework limits, so the production process should be qualified against the manufacturer’s process guidance. Control solder temperature and dwell, prevent solder wicking into the mating area, inspect for insufficient fill or bridging, and evaluate gold-to-mating-contact compatibility after the selected cleaning process.
• Q10: Can Molex 0901310932 be used in a humid or contaminated industrial environment? A10: Molex 0901310932 has a UL94 V-0 glass-filled polyester insulator and is RoHS3 compliant, but no ingress-protection rating or operating-temperature range is provided in the supplied specifications. In a humid, dusty, oily, or corrosive environment, the unshrouded 0901310932 interface may require an enclosure, conformal coating boundaries, protective covers, or a sealed mating connector. Validate insulation resistance, contact resistance, corrosion exposure, and vibration performance using the actual mating connector and enclosure.
