Parameter Comparison

Engineering Selection Recommendations

95278-802T40LF (Amphenol ICC - FCI)

This part is the direct manufacturer equivalent of the obsolete 95278-802T40. It maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance. The transition from Tin-Lead to Tin post finish aligns with modern manufacturing standards. This is the primary recommendation for direct replacement in new designs or production continuations.

0015911400 (Molex C-Grid 71308)

This Molex alternative meets all critical substitution parameters and carries active product status with ROHS3 compliance. The insulation material differs (LCP glass-filled versus thermoplastic) and insulation height is reduced by 0.010" (0.25mm), with contact length increased by 0.005" (0.13mm). These variations remain within acceptable mechanical tolerances for board-to-board connectivity. This option is suitable where Molex component standardization is preferred.

0015911404 (Molex C-Grid 71308)

This Molex variant is functionally equivalent to 0015911400 with identical mechanical specifications. The primary distinction is the mating contact finish, which is Tin rather than Gold. This part is appropriate for applications where gold plating is not required and cost optimization is a consideration. ROHS3 compliance and active product status are maintained.

Frequently Asked Questions (FAQ)

Q: Can 95278-802T40LF be used as a direct replacement for the obsolete 95278-802T40?

A: Yes. The 95278-802T40LF is the direct manufacturer equivalent with identical pin count, pitch, row spacing, mounting type, and fastening mechanism. The primary differences are active product status and RoHS compliance. The post finish change from Tin-Lead to Tin is a standard industry transition and does not affect functional compatibility.

Q: What are the key differences between Amphenol and Molex substitute options?

A: Both Molex parts (0015911400 and 0015911404) maintain the same 40-position, 2-row, 2.54mm pitch configuration. Mechanical variations include insulation material (LCP glass-filled versus thermoplastic), reduced insulation height (0.090" versus 0.100"), and slightly increased contact length (0.320" versus 0.315"). The primary functional difference between the two Molex options is mating contact finish: 0015911400 features gold plating while 0015911404 uses tin.

Q: Are there any compatibility concerns with the reduced insulation height in Molex parts?

A: The Molex insulation height of 0.090" (2.29mm) versus the original 0.100" (2.54mm) represents a 0.010" reduction. This variation falls within acceptable mechanical tolerances for board-to-board connector applications and does not compromise electrical or mechanical performance. PCB layout and mating connector specifications should be verified for the specific application.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring RoHS compliance and active product support, 95278-802T40LF is the recommended choice as the direct Amphenol equivalent. For designs requiring Molex standardization, 0015911400 is preferred for applications requiring gold-plated contacts, while 0015911404 is suitable for cost-optimized applications where tin plating is acceptable.

Q: What is the significance of the packaging differences listed?

A: The main part 95278-802T40 is listed with no specified packaging, while 95278-802T40LF is supplied in bulk packaging. The Molex parts are supplied in tube packaging. Packaging format does not affect component functionality but may influence procurement quantities and storage requirements.

Q: Are all substitute parts MSL 1 rated?

A: Yes. All parts listed—95278-802T40, 95278-802T40LF, 0015911400, and 0015911404—carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling.
