Amphenol ICC 50004-1344F High Density Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50004-1344F is a 344-position high-density backplane connector receptacle with female sockets, designed for through-hole, right-angle PCB mounting. This connector is part of the HPC™ series and features gold-plated contacts with a 0.100" (2.54mm) pitch across a 4-row by 86-column configuration. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure component availability for new production and field service applications.

Substitute Part Grouping Explanation

Substitution of the 50004-1344F is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle with female sockets in high-density configuration (HPC™ series)
• Electrical Configuration: 344 positions with 0.100" (2.54mm) pitch, 4-row by 86-column layout
• Mechanical Interface: Through-hole, right-angle mounting with solder termination
• Contact Specifications: Gold plating at 30.0µin (0.76µm) thickness
• Physical Features: Mating guide inclusion

The substitute part 50004-1344FLF maintains identical electrical and mechanical specifications while offering improved product status and regulatory compliance. Both parts share the same base product number (50004) and series designation (HPC™), confirming functional interchangeability within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

The 50004-1344FLF is the direct substitute for the obsolete 50004-1344F. Selection of the substitute part is justified on the following grounds:

Product Status: The 50004-1344FLF maintains active product status with current manufacturing support and inventory availability (902 pcs in stock), whereas the 50004-1344F is obsolete with limited remaining stock (1046 pcs).

Regulatory Compliance: The 50004-1344FLF achieves RoHS compliance, meeting current environmental and regulatory requirements for new designs and production. The original part is RoHS non-compliant, which may restrict its use in applications subject to RoHS directives.

Electrical and Mechanical Equivalence: Both parts are identical across all functional parameters including connector type, position count, pitch, mounting configuration, contact finish, and feature set. No design modifications are required for substitution.

Supply Chain Continuity: Use of the active substitute part ensures long-term component availability and eliminates obsolescence risk associated with the discontinued original part.

Frequently Asked Questions (FAQ)

Q: Are the 50004-1344F and 50004-1344FLF mechanically interchangeable?

A: Yes. Both parts are identical in mounting type (through-hole, right-angle), PCB footprint, connector orientation, and mating interface. No PCB redesign or mechanical modification is required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and RoHS compliance. The 50004-1344FLF is an active product with RoHS compliance, while the 50004-1344F is obsolete and RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use the 50004-1344FLF as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical electrical performance, contact specifications, and mechanical interface. No circuit design changes or PCB layout modifications are necessary.

Q: Does the RoHS compliance of the 50004-1344FLF affect performance?

A: No. RoHS compliance indicates material composition restrictions (elimination of lead and other hazardous substances) and does not alter electrical performance, contact reliability, or mechanical function. The contact finish, pitch, and all functional parameters remain unchanged.

Q: What is the MSL rating for both parts?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any other substitute options for the 50004-1344F?

A: Based on the provided parameters, the 50004-1344FLF is the direct equivalent. Substitution is limited to parts maintaining identical electrical configuration (344 positions, 0.100" pitch, 4×86 layout), connector type (receptacle, female sockets), mounting style (through-hole, right-angle), and contact specifications (gold plating, 30.0µin thickness).
