Substitute Part Grouping Explanation

Substitution for the 68439-372 is determined by the following critical parameters that must align across all candidate parts:

Connector type: Header
Contact type: Male Pin
Number of positions: 72
Number of rows: 2
Pitch - mating: 0.100" (2.54mm)
Row spacing - mating: 0.100" (2.54mm)
Mounting type: Through Hole
Termination: Solder
Fastening type: Push-Pull
Style: Board to Board
Shrouding: Unshrouded

The substitute parts BBD-136-G-C and BBD-136-T-C from Samtec Inc. meet all these core electrical and mechanical parameters. Both are active products, providing design continuity and improved availability compared to the obsolete Amphenol ICC part.

Engineering Selection Recommendations

Both Samtec BBD-136-G-C and BBD-136-T-C connectors serve as functional equivalents to the obsolete Amphenol ICC 68439-372. Selection between these two Samtec options depends on contact finish requirements:

BBD-136-G-C features gold mating contact finish, suitable for applications requiring enhanced corrosion resistance and signal integrity.

BBD-136-T-C features tin mating contact finish, appropriate for cost-sensitive applications where gold plating is not a requirement.

Both substitute parts are active products with ROHS3 compliance, providing regulatory advantage over the non-compliant original part. Both maintain MSL 1 rating and REACH unaffected status. Operating temperature range of -55°C to 125°C is specified for the Samtec parts, supporting extended thermal applications.

Frequently Asked Questions (FAQ)

Q: Can BBD-136-G-C and BBD-136-T-C be used interchangeably with 68439-372?

A: Both Samtec parts meet the core electrical and mechanical specifications: 72 positions, 2 rows, 0.100" pitch, through-hole solder termination, and push-pull fastening. The primary differences are contact finish (gold versus tin) and physical dimensions of contact elements. Board layout compatibility depends on PCB pad design and mating connector specifications.

Q: What are the physical dimension differences between the original and substitute parts?

A: The Samtec BBD-136 series has greater overall contact length (0.835" versus 0.720") and insulation height (0.585" versus 0.100"). These dimensional changes may affect board-to-board spacing and mating connector selection. PCB layout verification is required before implementation.

Q: Why is the original part obsolete?

A: The Amphenol ICC 68439-372 is classified as obsolete, indicating discontinued production. Samtec BBD-136 series parts provide active product alternatives with current manufacturing support and improved compliance status.

Q: What is the difference between BBD-136-G-C and BBD-136-T-C?

A: The primary distinction is mating contact finish: BBD-136-G-C uses gold plating for superior corrosion resistance, while BBD-136-T-C uses tin plating. Both share identical electrical and mechanical specifications otherwise.

Q: Are the substitute parts RoHS compliant?

A: Yes, both BBD-136-G-C and BBD-136-T-C are ROHS3 compliant, whereas the original 68439-372 is RoHS non-compliant. This provides regulatory advantage for new designs and updated production.

Q: What packaging is available for the substitute parts?

A: Both Samtec substitute parts are supplied in tube packaging, differing from the original part's unspecified packaging format.
