Amphenol ICC 50003-1136E High Density Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1136E is a 136-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 is designed for PCB-mounted applications requiring high-density interconnection in a 4-row by 34-column layout with 0.100" (2.54mm) pitch spacing.

The 50003-1136E carries an obsolete product status, which necessitates identification of active equivalent alternatives to ensure continued design support and procurement availability. The primary substitute maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1136E is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle configuration with female sockets in high-density format
• Position Count & Layout: Exactly 136 positions in 4×34 matrix
• Pitch & Spacing: 0.100" (2.54mm) pitch maintained
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Contact Specifications: Gold finish at 30.0µin thickness
• Series Designation: HPC™ series compatibility

The substitute part 50003-1136ELF meets all these criteria identically. The primary distinction is product lifecycle status and RoHS compliance certification, which do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1136ELF is the direct active equivalent for the obsolete 50003-1136E. Selection of the substitute part is justified on the following grounds:

Product Lifecycle: The 50003-1136E is classified as obsolete, limiting long-term procurement viability. The 50003-1136ELF maintains active product status, ensuring continued manufacturer support and supply chain stability.

Regulatory Compliance: The 50003-1136ELF achieves RoHS compliance, whereas the original part does not. For applications subject to RoHS directives or customer compliance requirements, the substitute part satisfies these regulatory obligations without any electrical or mechanical compromise.

Electrical & Mechanical Equivalence: All functional parameters—connector type, position count, pitch, mounting configuration, termination method, and contact specifications—are identical between the two parts. Direct substitution in existing designs requires no circuit modifications or PCB layout changes.

Inventory & Availability: The substitute part demonstrates superior inventory availability (1100 units versus 653 units), reducing procurement lead times and supply risk.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1136ELF be used as a direct replacement for the 50003-1136E in existing designs?

A: Yes. The 50003-1136ELF is electrically and mechanically identical to the 50003-1136E. No design modifications, PCB layout changes, or mating connector adjustments are required. The parts are fully interchangeable.

Q: What is the difference between the 50003-1136E and 50003-1136ELF part numbers?

A: The primary differences are product status and compliance certification. The 50003-1136E is obsolete and RoHS non-compliant. The 50003-1136ELF is an active product with RoHS compliance. All electrical and mechanical specifications are identical.

Q: Does the RoHS compliance of the 50003-1136ELF affect performance or reliability?

A: No. RoHS compliance relates to material composition and hazardous substance restrictions, not electrical performance or reliability. The substitute part maintains identical contact finish, gold plating thickness, and all functional specifications.

Q: Are there any compatibility concerns with mating connectors?

A: No. Both parts use the same HPC™ series connector interface with identical pitch (0.100"), position count (136), and mating guide features. Existing mating connectors designed for the 50003-1136E will mate identically with the 50003-1136ELF.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both the 50003-1136E and 50003-1136ELF carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply.

Q: Should I transition existing inventory of the 50003-1136E to the 50003-1136ELF?

A: Transition decisions depend on application requirements and compliance obligations. For new designs or applications requiring RoHS compliance, the 50003-1136ELF is the appropriate selection. Existing inventory of the 50003-1136E remains functionally valid for non-RoHS-restricted applications.
