Amphenol ICC 68690-372 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68690-372 is a rectangular connector header for through-hole mounting, featuring 72 positions arranged in 2 rows with 0.100" (2.54mm) pitch. This BERGSTIK® II series connector is designed for board-to-board applications with solder termination and push-pull fastening. The part is currently active in production with 766 units in stock.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative compliance certifications are required (such as RoHS compliance), or when specific contact post lengths are needed for different PCB stack-up configurations.

Engineering Selection Recommendations

Primary Substitutes (RoHS Compliant, Active Status):

The 3M 929715 series with EU or I designations (929715-01-36-EU, 929715-01-36-I, 929715-03-36-I, 929715-06-36-EU, 929715-10-36-EU, 929715-10-36-I) are recommended as primary substitutes. These parts are RoHS compliant, maintain active product status, and feature gold contact finish matching the original 68690-372 specification. Selection among these variants depends on required contact post length for PCB stack-up accommodation.

Secondary Substitutes (RoHS Compliant, Tin Finish):

The 3M 929710 series with RK designation (929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK) provides RoHS-compliant alternatives with tin contact finish and active product status. These are suitable for applications where gold finish is not required and cost optimization is a consideration.

Legacy Substitute (Last Time Buy):

The 929710-01-36 is available with 1267 units in stock but carries Last Time Buy status, indicating limited future availability. This part features tin-lead contact finish and RoHS non-compliance, making it suitable only for legacy system maintenance where original specifications must be preserved.

Contact Post Length Selection:

0.110" (2.79mm) post length: 929710-01-36, 929715-01-36-EU, 929715-01-36-I
0.175" (4.45mm) post length: 929710-10-36-RK, 929715-10-36-EU, 929715-10-36-I
0.410" (10.41mm) post length: 929715-03-36-I
0.710" (18.03mm) post length: 929710-06-36-RK, 929715-06-36-EU

Frequently Asked Questions (FAQ)

Q: Can I substitute the Amphenol ICC 68690-372 with any 3M 929 series connector?

A: Yes, all listed 3M 929 series connectors are mechanically and electrically compatible. The 72-position, 2-row configuration with 0.100" (2.54mm) pitch is identical across all variants. Selection depends on contact finish requirements, RoHS compliance needs, and contact post length for your specific PCB stack-up.

Q: What is the difference between the 929710 and 929715 series?

A: The primary difference is contact finish. The 929710 series uses tin or tin-lead finish, while the 929715 series uses gold finish. The 929715 series is recommended for applications requiring superior corrosion resistance and contact reliability. All other geometric and functional parameters are equivalent.

Q: Does contact post length affect mechanical compatibility?

A: Contact post length does not affect mating compatibility with the socket connector. Post length is determined by PCB thickness and solder joint requirements. Verify your PCB stack-up thickness and select the appropriate post length variant to ensure adequate solder joint formation and mechanical support.

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

A: Yes, both parts have identical 0.110" (2.79mm) contact post length and 72-position, 2-row configuration. The primary differences are contact finish (tin versus gold) and RoHS compliance status. Choose based on your application's corrosion environment and regulatory requirements.

Q: What does RoHS Compliant status mean for this connector?

A: RoHS compliance indicates the connector meets Restriction of Hazardous Substances regulations, with restricted levels of lead, cadmium, mercury, and other hazardous materials. The 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, and all 929715 variants are RoHS compliant. The original 68690-372 and 929710-01-36 are RoHS non-compliant.

Q: Why does the 929710-01-36 show Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this part number. While 1267 units are currently in stock, future availability is not guaranteed. For new designs or long-term production, select an active status part such as the 929710-01-36-RK or 929715 series variants.

Q: Can I mix different post length variants in the same assembly?

A: Mixing post length variants is not recommended. Maintain consistent post length across all 72 positions to ensure uniform solder joint quality and mechanical support. Select a single post length variant appropriate for your PCB thickness and assembly process.

Q: What is the significance of the EU and I designations in the 929715 part numbers?

A: The EU and I designations indicate regional compliance variants. EU designations comply with European regulations, while I designations comply with international standards. Both are RoHS compliant and functionally equivalent. Selection may depend on your market region or customer requirements.
