Amphenol ICC 79425-172 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 79425-172 is a rectangular connector header designed for through-hole mounting applications. This BERGSTIK® II series component features 72 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-board interconnection. The part is currently active in production with 749 units in stock. Equivalent and substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative compliance certifications are required, or when specific contact length configurations are needed for different PCB stack-up requirements.

Substitute Part Grouping Explanation

Substitute parts for the 79425-172 are qualified based on the following critical parameters that must remain constant:

Number of positions: 72
Number of rows: 2
Pitch spacing: 0.100" (2.54mm)
Connector type: Header with male pins
Mounting type: Through hole with solder termination
Contact shape: Square
Fastening type: Push-Pull
Insulation height: 0.100" (2.54mm)
Material flammability: UL94 V-0
Insulation color: Black

The substitute parts from Sullins Connector Solutions (PBC36 and PEC36 series) maintain these core parameters. Variations occur in contact length specifications (mating and post lengths), which determine the overall connector height and are selected based on specific PCB stack-up and application requirements. Contact finish differences (gold versus tin) and insulation material specifications (PBT) are also documented variations that do not affect the fundamental substitution eligibility.

Engineering Selection Recommendations

All substitute parts listed maintain active product status and are manufactured by Sullins Connector Solutions, an established connector supplier. The primary selection criterion is contact post length, which must align with the specific PCB stack-up thickness of the application.

For applications requiring RoHS3 compliance, all Sullins substitute parts (PBC36 and PEC36 series) are compliant, whereas the original 79425-172 is RoHS non-compliant. This distinction is significant for regulated industries and end-market requirements.

Contact finish selection between gold (PBC36 series) and tin (PEC36 series) depends on application requirements. Gold-plated contacts (PBC36DAAN, PBC36DABN, PBC36DACN, PBC36DAFN, PBC36DAHN) provide enhanced corrosion resistance. Tin-plated contacts (PEC36DAAN, PEC36DABN) offer cost efficiency while maintaining UL94 V-0 flammability certification.

All substitute parts are rated for 3A current and operate across -65°C to 125°C temperature range, specifications not provided for the original part. Insulation material for all substitutes is Polybutylene Terephthalate (PBT), providing consistent mechanical and thermal properties.

Frequently Asked Questions (FAQ)

Q: Can PBC36DAAN be used as a direct replacement for 79425-172?

A: PBC36DAAN is functionally equivalent for 72-position, 2-row, 0.100" pitch header applications. The primary difference is contact post length (0.120" for both), making it suitable for identical PCB stack-up configurations. PBC36DAAN is ROHS3 compliant, whereas 79425-172 is not.

Q: What determines which Sullins substitute part to select?

A: Contact post length is the primary selection criterion. PBC36DAAN and PEC36DAAN feature 0.120" post length (matching 79425-172). PBC36DABN and PEC36DABN feature 0.230" post length. PBC36DACN features 0.320" post length. PBC36DAFN features 0.620" post length. PBC36DAHN features 0.820" post length. Select based on your PCB thickness and mating connector depth requirements.

Q: What is the difference between PBC36 and PEC36 series?

A: Both series are 72-position, 2-row headers with identical mechanical dimensions and pitch spacing. The primary difference is contact finish: PBC36 series features gold-plated mating contacts, while PEC36 series features tin-plated mating contacts. Both maintain UL94 V-0 flammability rating and 3A current rating.

Q: Are all substitute parts compatible with the same mating connectors?

A: All substitute parts maintain identical mating contact length (0.230"), pitch spacing (0.100"), and row spacing (0.100"), ensuring compatibility with standard 0.100" pitch receptacle connectors. The variation in post length does not affect mating compatibility.

Q: Does the 79425-172 have a specified current rating?

A: The original 79425-172 does not specify a current rating in the provided documentation. All Sullins substitute parts are rated for 3A continuous current, providing a defined electrical specification for design purposes.

Q: What is the inventory status of substitute parts?

A: PEC36DAAN has the highest inventory at 13,229 units. PBC36DAAN has 8,210 units. PBC36DABN has 1,136 units. PBC36DACN has 1,328 units. PBC36DAFN has 1,032 units. PBC36DAHN has 974 units. PEC36DABN has 2,009 units. Availability should be confirmed for production requirements.
