Amphenol ICC 68779-672 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68779-672 is a BERGSTIK® II rectangular connector header designed for through-hole board-to-board applications. This 72-position, 2-row connector with 0.100" (2.54mm) pitch provides male pin contacts with gold or gold GXT™ finish on phosphor bronze material. The part is currently active in production with 879 pieces 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.

For Last Time Buy Situations: The 929710-01-36 (3M) is marked as Last Time Buy. For long-term supply assurance, select from the Active status parts: 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, or any 929715 series variant.

Frequently Asked Questions (FAQ)

Q: Can I use a 3M 929 series connector as a direct replacement for the Amphenol ICC 68779-672?

A: Yes, 3M 929 series connectors are qualified substitutes. All variants maintain the same 72-position, 2-row configuration with 0.100" (2.54mm) pitch, male pin contacts, through-hole solder termination, and push-pull fastening. However, verify that the contact post length matches your PCB stack-up requirements, as post lengths vary across the 929 series.

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 plating, while the 929715 series uses gold plating. Both series maintain identical mechanical dimensions and electrical characteristics. Select based on your application's contact finish requirements and environmental specifications.

Q: Does the contact post length affect mechanical compatibility?

A: Yes. The contact post length determines the overall connector height and affects PCB stack-up. The 68779-672 has a 0.318" post length (0.736" overall). Substitute parts range from 0.110" to 0.710" post lengths. Verify your PCB design accommodates the selected post length before substitution.

Q: Are all 3M 929 series variants RoHS compliant?

A: No. The 929710-01-36 is RoHS non-compliant (Last Time Buy status). All other variants listed (929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, and all 929715 series) are RoHS Compliant and currently active in production.

Q: What is the difference between -EU and -I suffix variants in the 929715 series?

A: The -EU and -I suffixes indicate different insulation material compositions. -EU variants use Polycyclohexylenedimethylene Terephthalate (PCT), while -I variants use Polybutylene Terephthalate (PBT) with polyester and glass filling. Both meet UL94 V-0 flammability requirements and operate across -40°C to 105°C. Select based on your specific insulation material requirements.

Q: Can I mix contact post lengths within a single connector assembly?

A: No. Each connector part number specifies a uniform post length across all 72 positions. Do not attempt to mix different post length variants within a single assembly.

Q: What is the current rating for these connectors?

A: The 3M 929 series connectors are rated for 2.5A per contact. The original 68779-672 does not specify a current rating in the provided data.
