Amphenol ICC 77313-852-72LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77313-852-72LF is a rectangular connector header with 72 positions at 2.54mm pitch, designed for through-hole board-to-board applications. This BERGSTIK® series connector features male pins with gold or gold GXT™ mating contact finish and operates across -65°C to 130°C. The part is currently in active product status with 771 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, when inventory constraints require alternative sourcing, or when design specifications allow for compatible connector variants with different contact post lengths or finish specifications.

Engineering Selection Recommendations

The 3M 929 series connectors provide direct substitution for the Amphenol ICC 77313-852-72LF across multiple variants. Selection criteria depend on application requirements and compliance mandates:

For RoHS-compliant applications: Parts 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, and all 929715 variants meet RoHS compliance. The 929710-01-36 is Last Time Buy status and should be avoided for new designs.

For gold-plated contact applications: The 929715 series (929715-01-36-EU, 929715-01-36-I, 929715-03-36-I, 929715-06-36-EU, 929715-10-36-EU, 929715-10-36-I) provides gold mating and post contact finishes, matching the primary part's gold finish specification.

For tin-plated contact applications: The 929710 series (929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK) provides tin contact finishes with RoHS compliance.

For post length matching: Part 929710-10-36-RK and 929715-10-36-EU/929715-10-36-I provide 0.175" (4.45mm) post length, closest to the primary part's 0.120" (3.05mm) specification. Parts 929710-06-36-RK and 929715-06-36-EU provide extended 0.710" (18.03mm) post length for applications requiring deeper PCB penetration.

For temperature-constrained applications: All 3M 929 series substitutes operate at -40°C to 105°C, which is narrower than the primary part's -65°C to 130°C range. Applications requiring the full -65°C to 130°C operating window must retain the Amphenol ICC 77313-852-72LF.

For current rating considerations: All 3M 929 series substitutes are rated at 2.5A per contact, compared to the primary part's 3A per contact. Applications requiring 3A per contact must retain the Amphenol ICC 77313-852-72LF.

Frequently Asked Questions (FAQ)

Q: Can 929710-01-36 be used as a direct replacement for 77313-852-72LF?

A: 929710-01-36 meets the core mechanical and electrical substitution criteria but carries Last Time Buy product status and is RoHS non-compliant. For new designs, use 929710-01-36-RK instead, which is Active status and RoHS compliant.

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

A: The 929715 series features gold mating and post contact finishes, while the 929710 series features tin or tin-lead finishes. Both series meet the 72-position, 2.54mm pitch core requirements. Select based on contact finish requirements and RoHS compliance mandates.

Q: Does post length variation affect mechanical compatibility?

A: Post length affects overall connector height and PCB stack-up depth. The 929710-10-36-RK and 929715-10-36-EU/929715-10-36-I variants at 0.175" (4.45mm) post length are closest to the primary part's 0.120" (3.05mm). Extended post variants (929710-06-36-RK and 929715-06-36-EU at 0.710" post length) require PCB design accommodation for deeper penetration.

Q: Are there temperature or current limitations with 3M 929 series substitutes?

A: Yes. All 3M 929 series substitutes operate at -40°C to 105°C (narrower than the primary part's -65°C to 130°C) and are rated at 2.5A per contact (lower than the primary part's 3A per contact). Applications requiring the full temperature range or higher current rating must use the Amphenol ICC 77313-852-72LF.

Q: Which substitute offers the best RoHS and product status alignment?

A: Parts 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, and all 929715 variants are Active status and RoHS compliant. The 929715 series additionally provides gold contact finishes matching the primary part's specification.

Q: What insulation material differences exist between substitutes?

A: The 929710-01-36 uses PBT with polyester and glass filler. The 929710-01-36-RK, 929710-06-36-RK, and 929710-10-36-RK use PCT. The 929715-01-36-I, 929715-03-36-I, and 929715-10-36-I use PBT with polyester and glass filler. The 929715-01-36-EU, 929715-06-36-EU, and 929715-10-36-EU use PCT. Material selection affects thermal and chemical resistance properties.
