Engineering Selection Recommendations

Primary Substitutes for Active Production:

The 3M 929 series connectors (929710-01-36-RK, 929710-03-36-RK, 929710-06-36-RK, 929710-10-36-RK, 929710-11-36-RK) and 929715 series (929715-01-36-EU, 929715-01-36-I) are recommended as primary substitutes. These parts maintain active product status and offer RoHS compliance, addressing regulatory requirements for new designs. Selection among these variants depends on required contact post length to accommodate specific PCB stack-up configurations.

Temperature Range Consideration:

The original 68693-172 operates to -65°C, while all 3M substitutes operate to -40°C minimum. Applications requiring operation below -40°C require design review and alternative component selection.

Current Rating Variance:

The original part is rated 3A, while most 3M substitutes are rated 2.5A. Applications requiring 3A continuous current should use the 3M 2372-6221-TG (3A rated, Active status) or conduct thermal analysis to confirm 2.5A adequacy.

RoHS Compliance Path:

For designs requiring RoHS compliance, select from the 929710-xx-36-RK or 929715-xx-36-EU/I variants. The 929710-01-36 and 929715-01-36-EU are non-compliant alternatives for legacy applications.

Contact Post Length Selection:

Post length variants accommodate different PCB thicknesses and mating depths. The 929710-01-36-RK (0.110" post) and 929715-01-36-EU (0.110" post) provide closest dimensional match to the original 0.520" overall contact length for standard applications. Longer post variants (929710-03-36-RK, 929710-06-36-RK) are for thicker PCB assemblies.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 68693-172 with any 3M 929 series connector?

A: Direct replacement requires matching contact post length to maintain PCB stack-up compatibility. The 929710-01-36-RK and 929715-01-36-EU provide closest dimensional equivalence. Verify overall contact length against your PCB thickness and mating depth requirements before substitution.

Q: What is the impact of the 2.5A vs 3A current rating difference?

A: The original 68693-172 is rated 3A. Most 3M substitutes are rated 2.5A. For applications operating at or near 3A, use the 3M 2372-6221-TG (3A rated) or conduct thermal analysis to confirm 2.5A adequacy for your specific current profile and ambient conditions.

Q: Are the 929710-01-36-RK and 929715-01-36-EU interchangeable?

A: Both maintain 72 positions, 2.54mm pitch, 2-row configuration, and 0.110" contact post length. Primary differences are contact finish (Tin vs Gold) and insulation material. They are mechanically and electrically interchangeable for standard applications. Contact finish selection depends on solderability and corrosion resistance requirements.

Q: Which substitute should I use for new designs requiring RoHS compliance?

A: Select from the 929710-xx-36-RK series or 929715-xx-36-EU/I variants, all marked RoHS Compliant. Choose post length based on PCB thickness: 929710-01-36-RK or 929715-01-36-EU for standard applications, 929710-03-36-RK or 929715-03-36-EU for thicker PCBs.

Q: What is the temperature operating range limitation?

A: The original 68693-172 operates -65°C to 130°C. All 3M substitutes operate -40°C to 105°C. Applications requiring operation below -40°C or above 105°C cannot use these substitutes and require alternative component selection.

Q: Why is 929710-01-36 marked "Last Time Buy" while 929710-01-36-RK is "Active"?

A: The 929710-01-36 is a legacy non-RoHS variant approaching end-of-life. The 929710-01-36-RK is the active RoHS-compliant equivalent. For new designs, specify the -RK variant to ensure long-term availability and regulatory compliance.

Q: Can I use 2372-6221-TG as a direct replacement?

A: The 2372-6221-TG maintains 72 positions, 2.54mm pitch, and 3A rating. However, its 0.120" contact post length differs from the original 0.520", resulting in different overall contact length (0.538" vs 0.938"). Verify PCB stack-up compatibility before substitution. This part is suitable for applications where shorter post length is acceptable.
