Frequently Asked Questions (FAQ)

Q: Can the Molex 0010977405 directly replace the TE Connectivity 1-104432-7?

A: The Molex 0010977405 is electrically and mechanically compatible with the 1-104432-7 within defined parameter tolerances. Both connectors feature 40 positions, 2 rows, 0.100" (2.54mm) pitch, square contacts, through-hole mounting, and UL94 V-0 flammability rating. The primary difference is the contact length specification: 0.320" (8.13mm) mating length versus 0.318" (8.08mm) on the original part. This 0.002" difference falls within acceptable mechanical tolerance for board-to-board applications. The 0010977405 is ROHS3 compliant, whereas the original part is RoHS non-compliant.

Q: What is the difference between the Molex C-Grid 70280 series and C-Grid III 90131 series?

A: Both series are compatible substitutes for the 1-104432-7 with identical pitch and position specifications. The C-Grid 70280 series (0010977405, 0010977406) features contact length specifications of 0.320" (8.13mm) mating and 0.110" (2.79mm) post, with Liquid Crystal Polymer (LCP) glass-filled insulation material. The C-Grid III 90131 series (0901310140, 0901310780, 0901310940) features shorter contact lengths of 0.266" (6.75mm) mating and 0.114" (2.90mm) post, with polyester glass-filled insulation material. Selection between these series depends on specific board thickness and mating depth requirements.

Q: Are the Amphenol ICC BERGSTIK® series connectors compatible with the 1-104432-7?

A: The Amphenol ICC BERGSTIK® series (77313-422-40LF, 77313-822-40LF) and BERGSTIK® II series (78548-140, 78548-140H, 78548-140HLF) are compatible substitutes. All maintain 40 positions, 2 rows, 0.100" (2.54mm) pitch, and square contact geometry. The BERGSTIK® series offers extended operating temperature range (-65°C to 130°C) and confirmed 3A per contact current rating. Contact length specifications vary: BERGSTIK® series features 0.305" (7.75mm) mating length, while BERGSTIK® II series features 0.318" (8.08mm) mating length, matching the original part specification.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging configurations: Bulk (Molex 0010977405, 0010977406, 0901310140, 0901310780; Amphenol ICC 78548-140, 78548-140H), Tray (Molex 0901310940), Bag (Amphenol ICC 77313-422-40LF, 77313-822-40LF, 78548-140HLF). Packaging selection does not affect electrical or mechanical compatibility; selection is based on inventory management and handling requirements.

Q: Which substitute part offers the best RoHS compliance status?

A: All Molex C-Grid series parts (0010977405, 0010977406, 0901310140, 0901310780, 0901310940) are ROHS3 compliant. Amphenol ICC BERGSTIK® series parts (77313-422-40LF, 77313-822-40LF) are RoHS compliant. Amphenol ICC BERGSTIK® II series part 78548-140HLF is RoHS compliant. Parts 78548-140 and 78548-140H are RoHS non-compliant. For applications requiring RoHS compliance, any of the compliant options listed above are suitable.

Q: What is the significance of contact finish differences between substitute parts?

A: The original 1-104432-7 features gold mating contact finish with 30.0µin (0.76µm) thickness. Substitute parts offer varying contact finish specifications: Molex 0010977405 features tin finish, while 0010977406 features gold with 15.0µin (0.38µm) thickness. Amphenol ICC BERGSTIK® series offers tin or gold finish options. Contact finish selection affects corrosion resistance and mating force characteristics but does not impact electrical compatibility within the specified voltage and current ratings.

Q: Are there any termination method differences that affect substitution?

A: The original 1-104432-7 supports both press-fit and solder termination. Most substitute parts support solder termination only. Amphenol ICC BERGSTIK® II series (78548-140, 78548-140H, 78548-140HLF) features kinked pin termination combined with solder. If press-fit termination is required for the application, compatibility must be verified against specific board design requirements. Solder termination is compatible with standard PCB assembly processes.

Q: What inventory availability should be considered when selecting a substitute?

A: Current inventory levels for active substitutes range from 710 to 3762 units. Molex 0901310780 (C-Grid III 90131) offers the highest inventory at 3762 units. Molex 0010977405 (C-Grid 70280) provides 1099 units. Amphenol ICC BERGSTIK® series parts offer 985 to 993 units. Amphenol ICC BERGSTIK® II series parts offer 710 to 1006 units. Inventory levels should be verified at time of procurement as availability is subject to change.

Q: Can the 1-104432-7 be used interchangeably with substitute parts in existing designs?

A: The 1-104432-7 is obsolete and no longer in production. Substitute parts are intended for new designs or redesigns of existing applications. Mechanical compatibility is confirmed within defined parameter tolerances for all listed substitutes. Electrical compatibility is maintained across all substitutes for the specified 3A current rating and voltage requirements. Design verification should confirm that contact length variations and insulation material differences do not impact specific application requirements.
