Amphenol ICC 78233-272 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78233-272 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 1116 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.

Substitute Part Grouping Explanation

Substitution eligibility for the 78233-272 is determined by the following critical parameters that must remain constant across all alternatives:

Connector type, contact type, and number of positions (72 positions, 2 rows)
Pitch and row spacing (0.100" / 2.54mm)
Mounting type (through hole) and termination method (solder)
Style (board to board), shrouding (unshrouded), and fastening type (push-pull)
Contact shape (square) and insulation height (0.100")
Material flammability rating (UL94 V-0) and insulation color (black)

The 3M 929 series parts listed below meet these core requirements. Variations among substitutes occur in:

Contact post length (ranging from 0.110" to 0.710")
Contact finish material (gold or tin)
Contact finish thickness
Insulation material composition
RoHS compliance status
Operating temperature range

These variations allow selection based on specific PCB design requirements and regulatory compliance needs.

Engineering Selection Recommendations

For RoHS Compliant Applications:

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. These parts meet RoHS requirements while maintaining electrical and mechanical compatibility with the 78233-272.

For Non-RoHS Applications with Active Product Status:

The 929710-01-36 (3M) is available but carries Last Time Buy status. For ongoing production, prioritize active status parts: 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, or the 929715 series variants.

For Contact Post Length Selection:

The 78233-272 has a contact post length of 0.150" (3.81mm). The closest 3M equivalent is 929710-10-36-RK at 0.175" (4.45mm). For applications requiring longer posts, 929710-06-36-RK and 929715-06-36-EU provide 0.710" (18.03mm) posts. For shorter posts, 929710-01-36, 929710-01-36-RK, 929715-01-36-EU, and 929715-01-36-I offer 0.110" (2.79mm) posts.

For Contact Finish Selection:

The 78233-272 specifies gold or gold GXT™ finish. Select 929715 series parts (929715-01-36-EU, 929715-01-36-I, 929715-03-36-I, 929715-06-36-EU, 929715-10-36-EU, 929715-10-36-I) for gold-plated contacts. The 929710 series provides tin or tin-lead finishes as alternatives.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 78233-272 with any 3M 929 series header?

A: Only 3M 929 series parts with matching core parameters are suitable substitutes. The critical requirements are 72 positions in 2 rows, 0.100" (2.54mm) pitch, through-hole solder termination, and push-pull fastening. Contact post length, contact finish material, and insulation material may vary based on application requirements.

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

A: The primary difference is contact finish. The 929710 series uses tin or tin-lead finishes, while the 929715 series uses gold finishes. Both series maintain identical electrical and mechanical compatibility with the 78233-272 in terms of position count, pitch, and mounting characteristics.

Q: Does contact post length affect compatibility?

A: Contact post length does not affect electrical compatibility but directly impacts PCB stack-up design. The 78233-272 has a 0.150" (3.81mm) post length. Substitute parts range from 0.110" to 0.710". Select the post length that matches your PCB thickness and assembly requirements.

Q: Are all listed substitutes RoHS compliant?

A: No. The 929710-01-36 is RoHS non-compliant. All other listed 3M 929 series parts are RoHS Compliant. Verify RoHS compliance requirements for your application before selection.

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

A: The -EU and -I suffixes indicate regional or packaging variants within the 929715 series. Both maintain identical electrical and mechanical specifications. Insulation material may differ (PCT versus PBT/Polyester/Glass Filled), but core connector functionality remains unchanged.

Q: Can I use 929710-01-36 in new production?

A: The 929710-01-36 carries Last Time Buy status, indicating limited availability. For new production designs, select from active status parts such as 929710-01-36-RK, 929710-06-36-RK, 929710-10-36-RK, or the 929715 series variants.

Q: What operating temperature range should I expect?

A: The 78233-272 does not specify an operating temperature range. All 3M 929 series substitutes operate from -40°C to 105°C, providing a defined thermal envelope for system design.
