Substitute Part Grouping Explanation

Substitute parts for the 68004-536 are qualified based on the following critical parameters that determine functional compatibility:

Connector Type & Contact Configuration: Header with male pin contacts
Position Count & Pitch: 36 positions at 0.100" (2.54mm) mating pitch
Mounting & Termination: Through-hole solder termination
Board Interface Style: Board-to-board connectivity

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 8-146274-6

The TE Connectivity 8-146274-6 provides the closest functional match to the 68004-536. Both connectors share identical mating pitch, position count, contact geometry, and mounting configuration. The TE part offers RoHS compliance and a defined operating temperature range (-65°C ~ 105°C), making it suitable for applications requiring regulatory compliance. The 0.090" insulation height represents a minor dimensional variation that does not affect standard board-to-board mating. Higher inventory availability (3080 units) supports supply chain continuity.

Secondary Substitute: 3M 929705-06-36-I

The 3M 929705-06-36-I meets all core substitution criteria with identical pitch, position count, and contact configuration. This part features RoHS compliance and an operating temperature range of -40°C ~ 105°C. The significantly longer post length (0.710" versus 0.107") requires verification for PCB stack-up compatibility. This part is suitable for applications where extended post length provides design advantages or where 3M connector ecosystem integration is preferred.

Compliance Considerations

The original 68004-536 is RoHS non-compliant. Both substitute parts are RoHS compliant, making them preferable for applications subject to RoHS regulations. All three parts maintain UL94 V-0 flammability compliance and MSL 1 moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 8-146274-6 directly replace the Amphenol ICC 68004-536 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (36), contact configuration (male pin, square shape), and board-to-board mounting style. The 0.090" insulation height on the TE part versus 0.100" on the Amphenol part represents a minor variation that does not affect standard mating performance. PCB footprints designed for the 68004-536 are compatible with the 8-146274-6.

Q: What is the significance of the post length difference between these parts?

A: Post length affects solder joint formation and PCB stack-up accommodation. The 68004-536 has a 0.107" post, the TE part has 0.125", and the 3M part has 0.710". Longer posts provide greater tolerance for thick PCBs or multiple board layers. Shorter posts require precise PCB thickness matching. Verify your PCB thickness and solder process parameters before selecting a substitute with significantly different post length.

Q: Are there compatibility issues with the different contact finishes?

A: Contact finish (gold versus tin) affects corrosion resistance and solderability. The 68004-536 uses gold finish, the TE part uses tin, and the 3M part uses gold. Tin-finished contacts (TE part) are standard for solder termination and provide excellent solderability. Gold-finished contacts (68004-536 and 3M part) offer enhanced corrosion resistance. Both finishes are compatible with standard PCB assembly processes. Material compatibility with your mating connector should be verified.

Q: Which substitute part should I select for new designs?

A: For new designs, the TE Connectivity 8-146274-6 is recommended. It provides RoHS compliance, a defined operating temperature range suitable for industrial applications, and strong inventory availability. The 3M 929705-06-36-I is suitable if your design requires the extended post length or if 3M connector ecosystem integration is a requirement.

Q: Are all three parts suitable for high-temperature applications?

A: The TE Connectivity 8-146274-6 supports -65°C ~ 105°C operation. The 3M 929705-06-36-I supports -40°C ~ 105°C operation. The original Amphenol ICC 68004-536 does not specify an operating temperature range. For applications requiring operation below -40°C, the TE part is the only qualified option among the three.

Q: What is the impact of different insulation materials on connector performance?

A: The 68004-536 does not specify insulation material. The TE part uses Liquid Crystal Polymer (LCP), and the 3M part uses glass-filled Polybutylene Terephthalate (PBT). Both LCP and glass-filled PBT are high-performance insulation materials with excellent dimensional stability and flame resistance (UL94 V-0). Material selection does not affect electrical performance for standard board-to-board applications.

Q: Can I mix and match these connector types in the same assembly?

A: No. While these parts are functionally equivalent for substitution purposes, they should not be mixed within a single assembly. Select one part number for your design and maintain consistency throughout production to ensure uniform performance and simplify inventory management.
