Amphenol ICC 76314-126 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76314-126 is a 52-position receptacle connector with 0.100" (2.54mm) pitch, gold-plated mating contacts, and through-hole solder termination. This BergCon® series connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The connector is designed for board-to-board or cable applications requiring reliable push-pull fastening and UL94 V-0 flammability compliance.

Substitute Part Grouping Explanation

Substitution for the 76314-126 is determined by the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 52 positions at 0.100" (2.54mm) mating pitch
Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
Mounting & Termination: Through-hole solder termination with push-pull fastening
Contact Finish: Gold-plated mating surface for corrosion resistance
Flammability & Compliance: UL94 V-0 material rating

Substitute parts are grouped into two categories:

Category A - Direct Functional Equivalents (Molex C-Grid 71850 Series): Parts 0015445152, 0015445852, and 0015446852 provide identical electrical and mechanical interfaces with active product status and RoHS3 compliance. These differ in contact finish thickness and mating contact material composition.

Category B - Alternative Socket Designs (Preci-Dip & Samtec): Parts from Preci-Dip 416 and 803 series, and Samtec ESD-126-G-03 offer equivalent 52-position, 2.54mm pitch socket configurations with alternative contact geometries (circular vs. square) and insulation materials. These provide functional substitution with extended operating temperature ranges and RoHS3 compliance.

Engineering Selection Recommendations

Molex C-Grid 71850 Series (0015445152, 0015445852, 0015446852) are the primary recommended substitutes. These parts maintain identical 52-position, 2.54mm pitch receptacle configuration with gold-plated mating contacts and push-pull fastening. All three variants are active products with RoHS3 compliance and specified operating temperature ranges (-40°C to 125°C or -40°C to 105°C). Part 0015445152 and 0015445852 provide gold mating finishes matching the original specification, while 0015446852 offers tin mating finish for applications where contact finish material is not critical. Current rating of 2.5A and 500VAC voltage rating are specified for all Molex variants.

Preci-Dip 416 and 803 Series (416-83-252-41-007101, 416-83-252-41-012101, 416-87-252-41-012101, 803-83-052-10-005101, 803-87-052-10-005101) provide alternative socket designs with circular contact geometry and beryllium copper contact material. These parts offer extended operating temperature range (-55°C to 125°C) and RoHS3 compliance. Insulation height and contact post length vary within these series; 803-83-052-10-005101 and 803-87-052-10-005101 match the original 0.335" (8.51mm) insulation height. Contact finish thickness varies from flash to 29.5µin (0.75µm).

Samtec ESD-126-G-03 is an elevated socket variant with the lowest mating contact finish thickness (10.0µin / 0.25µm) and highest contact post length (0.153" / 3.89mm). This part offers -55°C to 125°C operating range and RoHS3 compliance with liquid crystal polymer insulation material. The elevated socket design may require PCB layout accommodation.

All substitute parts maintain UL94 V-0 flammability compliance and MSL 1 (unlimited) moisture sensitivity rating. Selection should account for insulation height, contact post length, and contact finish thickness variations relative to PCB design requirements.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0015445152 as a direct replacement for Amphenol ICC 76314-126?

A: Yes. Both parts are 52-position receptacles with 0.100" (2.54mm) pitch, 2-row configuration, through-hole solder termination, and push-pull fastening. Molex 0015445152 provides gold mating contact finish matching the original specification. The primary difference is contact material (phosphor bronze vs. brass) and active product status with RoHS3 compliance.

Q: What is the difference between Molex 0015445152 and 0015445852?

A: Both are identical 52-position receptacles with gold mating contacts and 2.54mm pitch. The difference is contact finish thickness: 0015445152 has 30.0µin (0.76µm) gold thickness, while 0015445852 has 15.0µin (0.38µm). Both are RoHS3 compliant and rated for 2.5A at 500VAC.

Q: Why do Preci-Dip parts have circular contacts instead of square?

A: Preci-Dip 416 and 803 series use circular contact geometry with beryllium copper material, which provides different contact force and wear characteristics compared to square brass or phosphor bronze contacts. This is a design variation that maintains electrical and mechanical compatibility at the 2.54mm pitch and 52-position configuration.

Q: Does insulation height variation affect compatibility?

A: Insulation height affects the overall connector profile and mating stack height. The original 76314-126 has 0.335" (8.51mm) insulation height. Preci-Dip 803 series matches this dimension, while 416 series variants range from 0.354" to 0.394" (9.00mm to 10.00mm). Molex variants are 0.340" (8.64mm). Verify PCB clearance and mating connector specifications before selection.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are RoHS3 compliant. The original 76314-126 is RoHS non-compliant. If RoHS compliance is required for your application, any of the substitute parts satisfy this requirement.

Q: What is the difference between Preci-Dip 416-83 and 416-87 series?

A: Both are 52-position socket connectors with identical electrical and mechanical specifications. The difference is contact finish thickness: 416-83 series has 29.5µin (0.75µm) gold thickness, while 416-87 series has flash gold finish. Both maintain -55°C to 125°C operating range and RoHS3 compliance.

Q: Can I use Samtec ESD-126-G-03 in place of the original connector?

A: Samtec ESD-126-G-03 is functionally compatible as a 52-position, 2.54mm pitch socket with gold mating contacts and push-pull fastening. However, it is an elevated socket design with different insulation height (0.300" / 7.62mm) and longer contact post (0.153" / 3.89mm). Verify PCB layout compatibility and mating connector specifications before substitution.

Q: What is the current rating for the original 76314-126?

A: Current rating is not specified in the original part documentation. Molex substitute parts are rated for 2.5A per contact. Preci-Dip and Samtec parts are rated for 3A per contact. Verify application current requirements against selected substitute part ratings.
