Amphenol ICC 68779-272 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68779-272 is a BERGSTIK® II rectangular connector header designed for through-hole board-to-board applications. This vertical 72-position connector operates at 0.100" (2.54mm) pitch with male pin contacts and push-pull fastening. The part is currently active in production with 949 units in stock.

Substitute parts are necessary when the original manufacturer discontinues production, when alternative contact finishes or post lengths are required for specific PCB stackup configurations, or when RoHS compliance becomes a procurement requirement. The 68779-272 is RoHS non-compliant, making compliant alternatives essential for regulated applications.

Substitute Part Grouping Explanation

Substitution eligibility for the 68779-272 is determined by strict equivalence in the following parameters:

Connector type, contact type, and fastening mechanism (Header, Male Pin, Push-Pull)
Position count and row configuration (72 positions, 2 rows)
Mating pitch and row spacing (0.100" / 2.54mm)
Mounting method and termination (Through Hole, Solder)
Contact shape and insulation height (Square, 0.100")
Flammability and MSL ratings (UL94 V-0, MSL 1)

Substitute parts may vary in the following parameters without affecting functional compatibility:

Contact finish material (Gold vs. Tin-Lead vs. Tin)
Contact finish thickness
Contact post length (determines overall connector height and PCB stackup compatibility)
Insulation material composition (PBT vs. PCT)
RoHS compliance status
Product status (Active vs. Last Time Buy)

The 3M 929 series connectors meet all core electrical and mechanical requirements for direct substitution. Variations in post length (0.110", 0.175", 0.410", 0.710") accommodate different PCB stackup heights and mating depths.

Engineering Selection Recommendations

For applications requiring RoHS compliance, select from the 3M 929 series 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. All are currently active in production.

For non-regulated applications where RoHS compliance is not required, 929710-01-36 is available as a Last Time Buy option with tin-lead contact finish.

Contact post length selection depends on PCB stackup requirements. The 68779-272 features a 0.318" (8.08mm) post length. Equivalent post lengths are available in 929710-01-36 and 929715-01-36 variants (0.110"), 929710-10-36-RK and 929715-10-36 variants (0.175"), 929715-03-36-I (0.410"), and 929710-06-36-RK and 929715-06-36-EU (0.710").

Contact finish selection between gold and tin depends on application requirements. Gold-plated variants (929715 series) provide superior corrosion resistance. Tin-plated variants (929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK) offer cost optimization for non-corrosive environments.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 68779-272 with any 3M 929 series connector?

A: Direct replacement requires matching the contact post length to your PCB stackup configuration. The 68779-272 has a 0.318" post length. Select a 3M 929 variant with the same or compatible post length for your application. All 3M 929 series connectors maintain identical mating contact length, pitch, row spacing, and position count.

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

A: The primary difference is contact finish. The 929710 series uses tin-lead or tin plating, while the 929715 series uses gold plating. Gold-plated contacts provide enhanced corrosion resistance and are recommended for applications with extended shelf life or harsh environmental exposure. Both series are electrically and mechanically equivalent.

Q: Are all 3M 929 variants RoHS compliant?

A: No. The 929710-01-36 is RoHS non-compliant. All other variants listed (929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, and all 929715 series) are RoHS Compliant. Verify compliance requirements for your application before selection.

Q: How do I select the correct post length?

A: Post length determines the overall connector height and affects mating depth with the receptacle. Available post lengths are 0.110" (929710-01-36, 929715-01-36 variants), 0.175" (929710-10-36-RK, 929715-10-36 variants), 0.410" (929715-03-36-I), and 0.710" (929710-06-36-RK, 929715-06-36-EU). Measure your PCB stackup requirement and select the matching post length.

Q: What is the current rating for these connectors?

A: All 3M 929 series substitutes are rated for 2.5A per contact. The original 68779-272 does not specify a current rating in the provided data.

Q: Can I use tin-plated contacts instead of gold-plated?

A: Yes, if your application does not require gold plating. Tin-plated variants (929710 series) are electrically and mechanically equivalent to gold-plated variants (929715 series). Tin plating is suitable for standard industrial applications with normal environmental exposure.

Q: What is the operating temperature range?

A: All 3M 929 series connectors operate from -40°C to 105°C. The original 68779-272 does not specify an operating temperature range.

Q: Are there inventory considerations for these substitutes?

A: Yes. The 929710-01-36 is marked as Last Time Buy, indicating limited future availability. For long-term production, select from the Active status variants: 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, or any 929715 series part. Current inventory levels range from 768 to 1724 units across active variants.
