Amphenol ICC 77313-127-04 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77313-127-04 is a through-hole rectangular connector header with 4 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This BERGSTIK® series component features male pins with solder termination and push-pull fastening, designed for board-to-board or cable applications. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 77313-127-04 is determined by strict adherence to the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) - exact match required
• Number of Positions: 4 - exact match required
• Number of Rows: 2 - exact match required
• Row Spacing - Mating: 0.100" (2.54mm) - exact match required
• Contact Type: Male Pin - exact match required
• Mounting Type: Through Hole - exact match required
• Termination: Solder - exact match required
• Fastening Type: Push-Pull - exact match required
• Shrouding: Unshrouded - exact match required

All identified substitute parts meet these mandatory criteria. Variations in contact material, contact finish composition, insulation material type, and operating temperature ranges are permissible within the rectangular connector category, provided all critical parameters remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The 77313-127-04LF represents the direct manufacturer equivalent from Amphenol ICC (FCI), maintaining the BERGSTIK® series designation while transitioning from obsolete to active product status. This part is RoHS compliant and provides the highest compatibility assurance for existing designs.

For applications requiring RoHS3 compliance and extended operating temperature range, the M20-9760246 from Harwin Inc. offers -40°C ~ 105°C operation with 3A per contact current rating and cuttable connector features. The 826632-2 from TE Connectivity AMP Connectors provides the highest current rating at 5A with -65°C ~ 105°C operating range and ROHS3 compliance.

The 929665-09-02-I from 3M and BBD-102-G-A from Samtec Inc. are functionally equivalent alternatives with active product status and full RoHS compliance. The BBD-102-G-A operates across the widest temperature range (-55°C ~ 125°C) and features circular contact geometry, which may require mechanical verification for existing PCB layouts designed for square contacts.

All substitute parts maintain identical pitch, position count, row configuration, and fastening characteristics. Selection should prioritize compliance requirements, operating temperature specifications, and current rating demands specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 77313-127-04 be directly replaced with 77313-127-04LF?

A: Yes. The 77313-127-04LF is the direct active equivalent from the same manufacturer and series. All critical electrical and mechanical parameters are identical. The primary difference is product status transition from obsolete to active and RoHS compliance upgrade.

Q: What is the primary reason for substitution?

A: The 77313-127-04 is classified as obsolete. The 77313-127-04LF provides continuity within the same BERGSTIK® series with active availability and improved compliance status.

Q: Are all substitute parts mechanically interchangeable?

A: All substitute parts share identical pitch (0.100"), position count (4), row spacing (0.100"), and fastening type (push-pull). The BBD-102-G-A features circular contact geometry versus square contacts on other alternatives. PCB footprints designed for square contacts require verification before substituting with BBD-102-G-A.

Q: Which substitute offers the highest current rating?

A: The 826632-2 from TE Connectivity AMP Connectors provides 5A per contact, compared to 3A per contact for 77313-127-04LF and M20-9760246. The 929665-09-02-I provides 2.5A per contact.

Q: What are the RoHS compliance differences?

A: The original 77313-127-04 is RoHS non-compliant. All active substitutes (77313-127-04LF, 826632-2, 929665-09-02-I, BBD-102-G-A, M20-9760246) are RoHS compliant or ROHS3 compliant, meeting current regulatory requirements.

Q: Which substitute operates across the widest temperature range?

A: The BBD-102-G-A from Samtec Inc. operates from -55°C ~ 125°C. The 77313-127-04LF provides -65°C ~ 130°C, offering the highest upper temperature limit.

Q: Are packaging differences significant for procurement?

A: All substitute parts are supplied in bulk packaging. Inventory availability varies: M20-9760246 has the highest stock (12,636 pcs), followed by 826632-2 (2,513 pcs). Packaging format does not affect electrical or mechanical compatibility.
