Engineering Selection Recommendations

All substitute parts listed are active products with RoHS compliance and MSL 1 classification, meeting the regulatory and environmental requirements of the original Molex 0901310929.

Amphenol ICC (FCI) 77313-127-18LF and 77313-824-18LF are functionally equivalent with identical pitch, position count, and row configuration. The primary difference is contact material (phosphor bronze versus brass) and insulation material (thermoplastic versus polyester glass-filled). Both parts support extended operating temperature ranges (-65°C to 130°C) and are rated for 3A per contact. The 77313-824-18LF maintains identical contact length specifications to the original part.

Hirose Electric A1-18PA-2.54DSA(71) provides equivalent mechanical and electrical compatibility with brass contacts and PBT insulation. This part operates within -55°C to 85°C and includes a 200V voltage rating specification. Contact length variations are minor and within typical tolerance ranges for this connector class.

Harwin M20-9980945 offers equivalent performance with brass contacts and polyamide insulation. This part features a cuttable header design and operates within -40°C to 105°C. The M20 series supports mated stacking heights of 9.94mm, 10.64mm, 11.04mm, and 16.54mm, providing additional mechanical flexibility for specific board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can I use these substitute parts interchangeably with the Molex 0901310929?

A: Yes, all listed parts maintain the critical electrical and mechanical parameters: 18 positions, 2 rows, 0.100" (2.54mm) pitch, male pin configuration, through-hole solder termination, and push-pull fastening. Minor variations in contact length, insulation material, and operating temperature ranges exist but do not affect basic functional compatibility in standard applications.

Q: What are the key differences between the substitute parts?

A: Contact material varies between brass (Molex, Hirose, Harwin) and phosphor bronze (Amphenol). Insulation materials differ: polyester glass-filled (Molex), thermoplastic (Amphenol), PBT (Hirose), and polyamide (Harwin). Operating temperature ranges span -65°C to 130°C (Amphenol), -55°C to 85°C (Hirose), and -40°C to 105°C (Harwin). Contact finish thickness on mating surfaces varies from 8.00µin to 30.0µin.

Q: Are all substitute parts RoHS compliant?

A: Yes, all substitute parts are RoHS compliant. The Molex original and Harwin part are ROHS3 compliant, while Amphenol and Hirose parts are RoHS compliant.

Q: What is the moisture sensitivity level for these connectors?

A: All parts, including the original Molex 0901310929 and all substitutes, are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute part has the highest current rating?

A: All substitute parts are rated for 3A per contact, matching typical specifications for this connector class. The original Molex part does not specify a current rating in the provided data.

Q: Can I use the Harwin M20-9980945 in applications requiring specific stacking heights?

A: Yes, the Harwin M20-9980945 supports mated stacking heights of 9.94mm, 10.64mm, 11.04mm, and 16.54mm, providing flexibility for board-to-board spacing requirements. Other substitute parts do not specify stacking height options.

Q: What packaging options are available for these parts?

A: The Molex 0901310929 is supplied in standard packaging. Amphenol parts are available in bulk packaging, Hirose in tray packaging, and Harwin in bulk packaging. Packaging selection may affect lead times and minimum order quantities.

Q: Are there any temperature operating range limitations I should consider?

A: The Hirose A1-18PA-2.54DSA(71) operates within -55°C to 85°C, which is narrower than the Amphenol range (-65°C to 130°C). For applications requiring extended temperature performance, the Amphenol or Harwin options provide broader operating ranges.
