Amphenol ICC 68693-472 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68693-472 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 male pin contacts, solder termination, and push-pull fastening. The part is currently active in production with 875 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

For RoHS Compliant Applications:

Select from the 3M Series 929 parts with RoHS Compliant status: 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, 929715-01-36-EU, 929715-01-36-I, 929715-03-36-I, 929715-06-36-EU, 929715-10-36-EU, or 929715-10-36-I. These parts meet RoHS requirements and are suitable for regulated markets and applications requiring environmental compliance.

For Active Production Status:

All 3M Series 929 substitute parts except 929710-01-36 are designated as Active. The 929710-01-36 carries Last Time Buy status, indicating limited future availability. For long-term supply assurance, select from the remaining active alternatives.

For Contact Post Length Selection:

The original 68693-472 features a 0.520" (13.21mm) contact post length. Select substitute parts based on PCB stack-up requirements:

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

For Contact Finish Selection:

Tin-plated contacts (929710 series) provide standard electrical performance. Gold-plated contacts (929715 series) offer enhanced corrosion resistance and are suitable for applications requiring superior contact reliability in harsh environments or extended storage periods.

For Insulation Material Selection:

PCT (Polycyclohexylenedimethylene Terephthalate) insulation provides superior thermal and chemical resistance. PBT (Polybutylene Terephthalate) with glass filler offers cost-effective performance for standard applications. Both materials meet UL94 V-0 flammability requirements.

Frequently Asked Questions (FAQ)

Q: Can 3M Series 929 parts directly replace the Amphenol ICC 68693-472?

A: Yes, all listed 3M Series 929 parts are direct functional replacements. They maintain identical mating pitch (0.100"), position count (72), row configuration (2 rows), and mounting characteristics. Mechanical fit is guaranteed for the specified contact post lengths.

Q: What is the difference between tin and gold contact finishes?

A: Tin-plated contacts (929710 series) provide standard electrical conductivity and are suitable for general applications. Gold-plated contacts (929715 series) offer superior corrosion resistance, lower contact resistance, and extended shelf life. Gold plating is recommended for applications with extended storage, high-reliability requirements, or exposure to corrosive environments.

Q: How do I select the correct contact post length?

A: Contact post length determines the overall connector height and must match your PCB stack-up design. Measure the distance from the PCB surface to the mating connector interface. The original 68693-472 uses 0.520" posts. If your design accommodates different heights, shorter posts (0.110", 0.175") reduce overall height, while longer posts (0.410", 0.710") accommodate thicker PCB assemblies or additional components.

Q: What is the difference between PCT and PBT insulation materials?

A: PCT (Polycyclohexylenedimethylene Terephthalate) provides superior thermal stability and chemical resistance, making it suitable for high-temperature or chemically aggressive environments. PBT (Polybutylene Terephthalate) with glass filler offers cost-effective performance for standard industrial applications. Both materials meet UL94 V-0 flammability ratings.

Q: Are there RoHS-compliant alternatives to the 68693-472?

A: Yes. The original 68693-472 is RoHS non-compliant. All 3M Series 929 parts listed except 929710-01-36 are RoHS Compliant. For applications requiring RoHS compliance, select from 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, or any 929715 series part.

Q: What is the current rating for these connectors?

A: The 3M Series 929 substitute parts are rated for 2.5A per contact. The original 68693-472 does not specify a current rating. Verify that 2.5A per contact meets your application requirements.

Q: Why is 929710-01-36 marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer is discontinuing this part number. Existing inventory is available, but no future production is planned. For new designs or long-term supply requirements, select from the Active status alternatives.

Q: Can I mix different post lengths in the same application?

A: No. All connector headers in a single application must use the same post length to ensure uniform mating height and proper electrical contact alignment.
