Engineering Selection Recommendations

All three substitute parts satisfy the core mechanical and electrical compatibility requirements for the 68405-172. Selection should be based on the following factors:

3M 2372-5121-TG: This part is the manufacturer-recommended substitute and maintains the closest electrical specifications to the original, including the 5A current rating. However, it is RoHS non-compliant, matching the compliance status of the original part. The 3A current rating specification differs from the original 5A rating. Operating temperature range is -55°C to 105°C.

Samtec TSW-136-08-F-D-RA: This part offers ROHS3 compliance and an extended operating temperature range of -55°C to 125°C. Contact post length is 0.090" (2.29mm), closest to the original 0.095" specification. Phosphor bronze contact material matches the original. Current and voltage ratings are not specified.

Samtec TSW-136-10-G-D-RA: This part also offers ROHS3 compliance and the same extended operating temperature range of -55°C to 125°C. Contact post length is significantly longer at 0.390" (9.91mm), suitable for applications requiring extended post engagement. Phosphor bronze contact material matches the original. Current and voltage ratings are not specified.

For applications requiring RoHS3 compliance and extended temperature operation, either Samtec part is suitable. For legacy systems requiring exact electrical specification matching, the 3M part is appropriate despite non-compliance status.

Frequently Asked Questions (FAQ)

Q: Can the TSW-136-10-G-D-RA be used in place of the 68405-172 if the PCB layout was designed for the original part?

A: The TSW-136-10-G-D-RA has a significantly longer contact post (0.390" vs. 0.095"), which will affect PCB hole depth and mating engagement. PCB layout verification is required before substitution.

Q: What is the difference between the two Samtec TSW parts?

A: The primary difference is contact post length. TSW-136-08-F-D-RA has a 0.090" post length, closely matching the original 0.095" specification. TSW-136-10-G-D-RA has a 0.390" post length for extended engagement applications. Both share identical pitch, position count, and mounting configuration.

Q: Does the 3M 2372-5121-TG meet RoHS requirements?

A: No. The 3M part is RoHS non-compliant, matching the original 68405-172 status. For RoHS3 compliance, select either Samtec TSW part.

Q: Are there differences in insulation height between the substitute parts?

A: Yes. The original part has 0.190" insulation height. The 3M part is 0.242", and both Samtec parts are 0.219". These differences may affect mating clearances and should be verified against mating connector specifications.

Q: What is the current rating for the Samtec TSW parts?

A: Current ratings are not specified for the Samtec TSW-136-08-F-D-RA and TSW-136-10-G-D-RA. The original 68405-172 is rated at 5A, and the 3M substitute is rated at 3A. Contact Samtec directly for current rating specifications if this parameter is critical to your application.

Q: Can these parts be used interchangeably in existing designs?

A: Mechanical and electrical compatibility exists for all three substitutes based on core parameters. However, differences in contact post length, insulation height, and current ratings require design verification before implementation in production.
