Substitute Part Grouping Explanation

Substitution for the 68405-472 is determined by strict equivalence across the following critical parameters:

Connector type: Header
Contact type: Male Pin
Pitch - mating: 0.100" (2.54mm)
Number of positions: 72
Number of rows: 2
Row spacing - mating: 0.100" (2.54mm)
Mounting type: Through Hole, Right Angle

Engineering Selection Recommendations

Active Product Status Priority: TSW-136-08-F-D-RA and TSW-136-10-G-D-RA (Samtec) are both active products with current manufacturing support. These are preferred for new designs and long-term procurement stability.

RoHS Compliance: The Samtec TSW series (TSW-136-08-F-D-RA and TSW-136-10-G-D-RA) are ROHS3 compliant, whereas the main part and other substitutes are RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulations.

Current Rating Consideration: The main part 68405-472 is rated at 5A, while 3M 2372-5121-TG and TE 4-103795-0-36 are rated at 3A. Samtec parts do not specify current rating. Applications requiring the full 5A rating should account for this difference.

Contact Post Length Variation: TSW-136-10-G-D-RA features an extended contact post length of 0.390" (9.91mm) compared to the main part's 0.095" (2.41mm). This variation affects board-to-board stacking height and must be evaluated for mechanical fit in the target application.

Operating Temperature Range: Samtec parts support -55°C ~ 125°C, exceeding the 3M part's -55°C ~ 105°C range. TE part supports -65°C ~ 105°C. The main part does not specify operating temperature.

Frequently Asked Questions (FAQ)

Q: Can I substitute 68405-472 with any of these four parts?

A: All four substitute parts meet the core electrical and mechanical requirements: 72-position, 2.54mm pitch, right-angle through-hole header with square male pins and solder termination. However, verify application-specific requirements for current rating, operating temperature, RoHS compliance, and contact post length before selection.

Q: What is the difference between TSW-136-08-F-D-RA and TSW-136-10-G-D-RA?

A: Both are Samtec TSW series headers with identical pitch, position count, and mounting type. The primary differences are contact post length (0.090" vs. 0.390"), contact finish thickness on the post (not specified vs. 3.00µin), and both feature gold mating finish. TSW-136-10-G-D-RA is suitable for applications requiring extended post length for deeper board penetration.

Q: Why is the 3M 2372-5121-TG rated at 3A instead of 5A?

A: Current rating is determined by contact material, contact geometry, and insulation design. The 3M part uses copper alloy contacts versus the main part's phosphor bronze, resulting in a lower current rating. Verify that 3A meets application requirements before substitution.

Q: Are the Samtec parts RoHS compliant?

A: Yes, both TSW-136-08-F-D-RA and TSW-136-10-G-D-RA are ROHS3 compliant. The main part and other substitutes are RoHS non-compliant. Select Samtec parts for applications requiring RoHS compliance.

Q: What does "Discontinued at DiGi Electronics" mean for the TE 4-103795-0-36?

A: This indicates the part is no longer actively distributed through DiGi Electronics but may remain available through other channels or direct from TE Connectivity. Verify current availability before design commitment.

Q: Can I use these parts interchangeably in existing designs?

A: Mechanical fit must be verified, particularly regarding insulation height and contact post length variations. The TE part features a breakaway connector type, which may affect mechanical compatibility. Conduct physical fit testing before production transition.
