Amphenol ICC 50003-1300E Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1300E is a 300-position high-density backplane connector featuring female sockets in a through-hole, right-angle configuration. This receptacle connector is part of the HPC™ series and utilizes a 0.100" (2.54mm) pitch across 4 rows and 75 columns. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure ongoing component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1300E is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets; High Density configuration)
• Position count and array geometry (300 positions; 4 rows × 75 columns)
• Pitch specification (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Contact material and finish (Gold, 30.0µin thickness)
• Presence of mating guide feature

The substitute part 50003-1300ELF meets all these criteria and is therefore electrically and mechanically interchangeable with the original part. The primary distinction between these parts is product status and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1300ELF is the direct functional equivalent of the 50003-1300E. Selection between these parts should be based on the following criteria:

For new designs and production: The 50003-1300ELF is the appropriate choice. This part carries Active product status, ensuring long-term availability and supply chain stability. Additionally, it meets RoHS compliance requirements, which is mandatory for applications subject to environmental and regulatory standards in most markets.

For legacy system maintenance: The 50003-1300E remains available in current inventory (1095 pcs) and may be used for direct replacement in existing assemblies where RoHS compliance is not a requirement and the obsolete status does not conflict with procurement policies.

Both parts are identical in electrical and mechanical function, connector geometry, contact specifications, and termination characteristics. The choice between them is driven by product lifecycle status and regulatory compliance needs rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1300E and 50003-1300ELF mechanically interchangeable?

A: Yes. Both parts share identical connector geometry, position count (300), pitch (0.100"), row/column configuration (4×75), mounting type (through-hole right-angle), and contact specifications. They are direct mechanical substitutes.

Q: What is the significance of the "ELF" suffix in the 50003-1300ELF part number?

A: The "ELF" suffix indicates RoHS compliance. The 50003-1300ELF meets RoHS regulatory requirements, whereas the 50003-1300E does not. This is the primary technical distinction between the two parts.

Q: Can I use the 50003-1300E in a new design?

A: The 50003-1300E is classified as obsolete. While it remains available in inventory, new designs should specify the 50003-1300ELF to ensure compliance with current regulatory standards and to avoid future supply chain constraints.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical contact finish (gold, 30.0µin thickness), termination method (solder), and feature set (mating guide). Electrical performance is equivalent.

Q: What is the moisture sensitivity level for these connectors?

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

Q: Can these connectors be used in high-temperature applications?

A: Operating temperature specifications are not provided in the component data. Consult the manufacturer's detailed datasheet for thermal performance limits.
