Amphenol ICC 68423-136 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68423-136 is a through-hole, right-angle rectangular connector header with 36 positions at 0.100" (2.54mm) pitch, designed for board-to-board applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Pitch: 36 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole, right-angle, solder termination
• Electrical Performance: 3A current rating, gold mating surface finish
• Environmental Compliance: UL94 V-0 flammability rating, operating temperature range

The substitute parts listed below maintain these core electrical and mechanical specifications. Variations in contact post length, insulation height, and compliance certifications are noted but do not affect functional interchangeability in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Amphenol ICC 68458-136HLF

The 68458-136HLF is the direct functional equivalent from the same manufacturer and series (BERGSTIK® II). It maintains identical position count (36), pitch (0.100"), mating contact length (0.318"), and electrical ratings (3A, gold finish). The primary distinction is product status: 68458-136HLF is active and RoHS compliant, whereas the original 68423-136 is obsolete and non-compliant. Contact post length differs by 0.010" (0.26mm), which is within typical PCB tolerance ranges for through-hole applications.

Secondary Substitute: Molex 0022288365

The 0022288365 maintains 36 positions at 0.100" pitch with identical mounting and termination characteristics. It is RoHS3 compliant and actively manufactured. Mating contact length is 0.006" (0.15mm) longer than the original. This part is suitable for applications where Molex series compatibility is acceptable and RoHS compliance is required.

Alternative with Position Variance: TE Connectivity 9-146305-0

The 9-146305-0 is a 40-position header at 0.100" pitch from the AMPMODU Mod II series. While it exceeds the original position count by 4, it maintains identical pitch, mounting type, and electrical ratings (3A, gold finish). This part is suitable only when the additional positions can be accommodated in the design or when unused positions are acceptable. Operating temperature range is reduced to -65°C ~ 105°C compared to the original -65°C ~ 130°C specification.

Frequently Asked Questions (FAQ)

Q: Can 68458-136HLF be used as a direct replacement for 68423-136?

A: Yes. Both parts are 36-position headers at 0.100" pitch with identical mating contact length and electrical ratings. The 0.010" difference in post length is within standard PCB hole tolerance and does not affect functional compatibility in board-to-board applications.

Q: What is the primary reason to substitute the obsolete 68423-136?

A: The original part is obsolete and non-RoHS compliant. The 68458-136HLF provides active production status, RoHS compliance, and identical electrical and mechanical specifications, making it the recommended replacement.

Q: Is the Molex 0022288365 compatible with designs using the original Amphenol connector?

A: Yes, for standard board-to-board applications. The 0022288365 maintains 36 positions at 0.100" pitch with equivalent mating contact length and gold finish. Mechanical fit should be verified if the connector is used with existing mating receptacles designed for Amphenol BERGSTIK® II series.

Q: Why is the TE Connectivity 9-146305-0 listed as a substitute if it has 40 positions instead of 36?

A: The 9-146305-0 is listed as a functional alternative for applications where the additional 4 positions can be utilized or left unconnected. It maintains identical pitch, mounting type, and electrical ratings. This part is suitable only when design modifications to accommodate 40 positions are feasible.

Q: What is the impact of the 0.010" post length difference between 68423-136 and 68458-136HLF?

A: Standard PCB through-hole tolerances typically accommodate ±0.010" variation in post length. This difference does not affect solder joint quality or mechanical retention in standard applications. Verification with specific PCB design specifications is recommended for high-reliability applications.

Q: Are there temperature rating differences between substitute parts?

A: Yes. The original 68423-136 and 68458-136HLF both operate from -65°C to 130°C. The Molex 0022288365 does not specify an operating temperature range. The TE Connectivity 9-146305-0 operates from -65°C to 105°C, which is 25°C lower than the original specification. Application temperature requirements must be verified before selection.

Q: What packaging formats are available for these substitute parts?

A: The 68458-136HLF and 0022288365 are supplied in bulk packaging. Verify packaging requirements with your procurement specifications, as bulk packaging may differ from the original part's packaging format.
