Amphenol ICC 68743-472 Rectangular Connector Header — Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68743-472 is a through-hole rectangular connector header with 72 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This BERGSTIK® II series component features male pins with solder termination and push-pull fastening, designed for board-to-board applications. The part is currently active in production with 1070 units in stock.

Substitute parts become necessary when the original part reaches end-of-life status, when alternative compliance certifications are required (such as RoHS compliance), or when specific contact post lengths must be adjusted for application-specific PCB stack-up requirements.

Engineering Selection Recommendations

For RoHS Compliance Requirements: The 68743-472 is RoHS non-compliant. All 3M 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, and all 929715 series variants are RoHS Compliant. Select based on contact post length and contact finish requirements.

For Active Product Status: The 68743-472 is currently Active. Among substitutes, 929710-01-36 carries Last Time Buy status; all other 3M variants are Active. For long-term supply assurance, prioritize Active status parts.

For Contact Post Length Selection: The 68743-472 has a 0.220" (5.58mm) post length. Matching post lengths are available in:

929710-10-36-RK and 929715-10-36-EU/929715-10-36-I at 0.175" (4.45mm) — closest available
929710-01-36-RK and 929715-01-36-EU/929715-01-36-I at 0.110" (2.79mm) — shorter post
929710-06-36-RK and 929715-06-36-EU at 0.710" (18.03mm) — longer post
929715-03-36-I at 0.410" (10.41mm) — intermediate length

For Contact Finish Selection: The 68743-472 uses Tin finish. Tin-finish substitutes include 929710-01-36 (Tin-Lead, Last Time Buy status) and all 929710-RK variants (Tin, Active status). Gold-finish variants (929715 series) provide enhanced corrosion resistance and are all RoHS Compliant and Active.

For Insulation Material Compatibility: The 68743-472 insulation material is not specified. Substitutes use either PBT with glass filler/Polyester or PCT. PCT variants (929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, 929715-06-36-EU, 929715-10-36-EU) offer superior thermal and chemical resistance.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 68743-472 with any 3M 929 series header?

A: Only 3M parts listed in this document are qualified substitutes. All substitutes maintain identical connector type, position count, pitch, row spacing, mounting method, termination, and fastening type. However, contact post length, contact finish, and insulation material vary. Selection depends on your specific PCB stack-up and environmental requirements.

Q: What is the difference between 929710-01-36 and 929710-01-36-RK?

A: Both have identical 0.110" (2.79mm) contact post length and 0.100" (2.54mm) mating pitch. The primary differences are: 929710-01-36 uses Tin-Lead finish with 100.0µin thickness and is Last Time Buy status; 929710-01-36-RK uses Tin finish with 200.0µin thickness, is RoHS Compliant, and is Active status. The -RK variant is recommended for new designs.

Q: Why do the 929715 series parts cost more than 929710 series?

A: The 929715 series uses Gold contact finish (10.0µin thickness) instead of Tin, providing superior corrosion resistance and lower contact resistance. All 929715 variants are RoHS Compliant and Active status. Selection between Tin and Gold depends on application environment and reliability requirements.

Q: Which substitute has the closest contact post length to the original 68743-472?

A: The 68743-472 has a 0.220" (5.58mm) post length. The closest available substitute is 929710-10-36-RK or 929715-10-36-EU/929715-10-36-I at 0.175" (4.45mm). If exact post length is critical for your PCB stack-up, verify mechanical clearance before substitution.

Q: Are all these substitutes rated for the same operating temperature?

A: The 68743-472 operating temperature is not specified. All 3M substitutes are rated -40°C ~ 105°C. If your application requires operation outside this range, verify the original part's temperature rating before substitution.

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

A: PCT (Polycyclohexylenedimethylene Terephthalate) offers superior thermal stability and chemical resistance compared to PBT (Polybutylene Terephthalate) with glass filler. PCT variants are preferred for high-temperature or chemically aggressive environments. Both materials maintain UL94 V-0 flammability rating.

Q: Can I mix and match contact post lengths in a single application?

A: No. All 72 positions in a header must use the same contact post length to ensure uniform mating height and connector alignment. Select a single substitute part number for your entire assembly.

Q: Is the 929710-01-36 (Last Time Buy) still available for new designs?

A: While 1267 units are currently in stock, Last Time Buy status indicates no future production. For new designs, use Active status alternatives: 929710-01-36-RK (Tin, RoHS Compliant) or 929715-01-36-EU/929715-01-36-I (Gold, RoHS Compliant).
