50004-1320E Equivalent & Substitute Parts

Part Overview

The 50004-1320E is a 320-position high-density backplane connector receptacle manufactured by Amphenol ICC (FCI). This component features female sockets in a through-hole, right-angle configuration with a 0.100" (2.54mm) pitch across 4 rows and 80 columns. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50004-1320E is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Must be Receptacle with Female Sockets in High Density (HPC) configuration
• Position Count & Layout: Exactly 320 positions arranged in 4 rows × 80 columns
• Pitch & Spacing: 0.100" (2.54mm) pitch maintained across all positions
• Mounting & Termination: Through-hole, right-angle mounting with solder termination
• Contact System: Gold-plated contacts with 30.0µin (0.76µm) finish thickness
• Series Compatibility: HPC™ series designation

The 50004-1320ELF qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status: the original part is obsolete, while the substitute is active in production with improved RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 50004-1320ELF is the direct equivalent for the obsolete 50004-1320E. Selection of the substitute part is based on the following engineering criteria:

Product Status: The original part is obsolete and no longer manufactured. The substitute is active in production, ensuring long-term availability and supply chain stability.

RoHS Compliance: The 50004-1320ELF meets RoHS compliance requirements, whereas the original part does not. For applications subject to RoHS regulations or environmental standards, the substitute is the appropriate choice.

Electrical & Mechanical Equivalence: All functional parameters—connector type, position count, pitch, mounting configuration, and contact specifications—are identical between the two parts. No design modifications are required for substitution.

Inventory & Lead Time: The substitute part maintains higher stock levels (1138 pcs vs. 853 pcs), supporting faster procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can the 50004-1320ELF be used as a direct replacement for the 50004-1320E in existing designs?

A: Yes. The 50004-1320ELF is electrically and mechanically identical to the 50004-1320E. All connector parameters—position count, pitch, mounting type, and contact specifications—are equivalent. No PCB layout or mating connector modifications are necessary.

Q: What is the primary difference between these two parts?

A: The 50004-1320E is obsolete and non-RoHS compliant. The 50004-1320ELF is an active production part with RoHS compliance. Both parts share identical electrical and mechanical specifications.

Q: Are there any compatibility concerns when substituting the 50004-1320ELF for the 50004-1320E?

A: No compatibility concerns exist. Both parts are from the same HPC™ series, manufactured by Amphenol ICC (FCI), and feature identical connector geometry, contact layout, and termination methods. Mating connectors designed for the original part will function identically with the substitute.

Q: Does the RoHS compliance status of the 50004-1320ELF affect its electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. The contact finish, pitch, and electrical characteristics remain unchanged.

Q: What is the moisture sensitivity level for both parts?

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