Amphenol ICC 48251-000 Socket Contact Rectangular Connector — Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 48251-000 is a socket contact connector designed for 22-26 AWG wire gauges with gold plating and crimp termination. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing procurement and design continuity. The Mini-PV™ series connector serves applications requiring reliable rectangular connector interfaces with standardized electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 48251-000 is determined by the following critical parameters:

• Wire gauge compatibility: 22-26 AWG
• Contact termination method: Crimp
• Contact finish: Gold
• Connector category: Rectangular Connectors
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must maintain these electrical and mechanical specifications to ensure functional equivalence. The identified substitutes fall into two categories:

1. Direct Amphenol ICC Substitute: 48251-000LF — same manufacturer, same series, active product status with RoHS compliance upgrade
2. Cross-Manufacturer Substitutes: Molex KK 2578 series contacts (0008550123, 0008550137, 0008580125) — functionally equivalent non-gendered contacts with matching wire gauge and termination specifications

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 48251-000LF

The 48251-000LF is the preferred substitute. It maintains identical electrical and mechanical specifications to the obsolete 48251-000 while offering active product status and RoHS compliance. This part is sourced from the same manufacturer and series, ensuring design compatibility without connector interface modifications.

Secondary Recommendations: Molex KK 2578 Series (0008550123, 0008550137, 0008580125)

The Molex contacts are functionally equivalent alternatives when cross-manufacturer substitution is acceptable. All three parts meet the core electrical requirements: 22-26 AWG wire gauge, crimp termination, gold finish, and MSL 1 rating. These parts are active products with ROHS3 compliance.

Selection among the Molex options depends on contact finish thickness requirements:

• 0008550123 and 0008550137: 30.0µin (0.76µm) gold thickness
• 0008580125: 15.0µin (0.38µm) gold thickness, matching the original specification

All substitute parts are available in production quantities with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can 48251-000LF be used as a direct replacement for 48251-000?

A: Yes. The 48251-000LF maintains identical electrical and mechanical specifications, including wire gauge (22-26 AWG), contact termination (crimp), contact finish (gold at 15.0µin), and MSL rating (1). The primary difference is product status (active vs. obsolete) and RoHS compliance upgrade.

Q: What is the difference between socket and non-gendered contacts?

A: The 48251-000 is a socket contact, while Molex KK 2578 series contacts are non-gendered. Socket contacts are designed to receive pin contacts in a mated pair. Non-gendered contacts can function in either role depending on connector housing design. Substitution feasibility depends on the specific connector housing and mating requirements of your application.

Q: Why do the Molex contacts have thicker gold plating?

A: Contact finish thickness is a manufacturing specification that affects durability and wear resistance. The 0008550123 and 0008550137 feature 30.0µin (0.76µm) plating compared to the original 15.0µin (0.38µm). The 0008580125 matches the original thickness at 15.0µin (0.38µm). Selection should align with your application's contact mating cycle and environmental requirements.

Q: Are all substitutes RoHS compliant?

A: The 48251-000LF is RoHS Compliant. The Molex parts (0008550123, 0008550137, 0008580125) are ROHS3 Compliant. The original 48251-000 is RoHS non-compliant. If RoHS compliance is a design requirement, use 48251-000LF or the Molex alternatives.

Q: What packaging formats are available?

A: The 48251-000LF is supplied in Box packaging. The Molex contacts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Packaging selection depends on your procurement and assembly workflow.

Q: Can I mix socket and non-gendered contacts in the same connector assembly?

A: Connector compatibility depends on the specific housing design. Socket contacts are designed for use with pin contacts in gendered connector systems. Non-gendered contacts may not be mechanically compatible with housings designed for gendered socket-pin pairs. Verify housing specifications before substituting socket contacts with non-gendered alternatives.
