Amphenol ICC 50003-1052F High Density Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1052F is a 52-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 mounting applications requiring high-density interconnection in a 4-row by 13-column layout with 0.100" (2.54mm) pitch spacing.

The 50003-1052F carries an obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement. The primary substitute maintains identical electrical and mechanical specifications while offering active product status and improved compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1052F is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count (52 positions)
• High-density connector style classification
• Pitch specification (0.100" / 2.54mm)
• Physical configuration (4 rows, 13 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact material and finish (Gold plating)

The substitute part 50003-1052FLF meets all these criteria identically. The primary distinction lies in product lifecycle status and RoHS compliance, not in electrical or mechanical form, fit, or function.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1052FLF is the direct functional equivalent of the 50003-1052F. Both parts share identical electrical and mechanical specifications, including connector geometry, contact configuration, pitch, and mounting characteristics.

Selection between these parts should be based on the following factors:

For new designs or active procurement: The 50003-1052FLF is the appropriate choice. It maintains active product status with Amphenol ICC, ensuring continued availability and manufacturing support. The part carries RoHS compliance certification, meeting regulatory requirements for applications subject to RoHS directives.

For legacy system support: The 50003-1052F remains functionally interchangeable with the 50003-1052FLF in existing assemblies. However, procurement of the obsolete variant may face extended lead times and limited inventory availability.

For compliance-sensitive applications: The 50003-1052FLF's RoHS compliant status makes it the required choice for applications operating under RoHS regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1052F and 50003-1052FLF mechanically interchangeable?

A: Yes. Both parts are identical in form, fit, and function. They share the same 52-position, high-density configuration with 0.100" pitch, 4-row by 13-column layout, through-hole right-angle mounting, and gold-plated contact finish.

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

A: The 50003-1052FLF is the active production variant with RoHS compliance certification. The 50003-1052F is obsolete. Both maintain identical electrical and mechanical specifications.

Q: Can I use the 50003-1052FLF as a direct replacement in existing assemblies designed for the 50003-1052F?

A: Yes. The parts are functionally equivalent with no design modifications required. PCB layouts, mating connectors, and assembly processes remain unchanged.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical characteristics. Both parts deliver identical electrical performance.

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

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

Q: Are there any other equivalent part numbers in the HPC™ series with the same 52-position configuration?

A: Based on the provided specifications, the 50003-1052FLF is the direct equivalent. Substitution eligibility is strictly limited to parts matching all critical parameters: 52 positions, 0.100" pitch, 4×13 configuration, through-hole right-angle mounting, and female socket receptacle type.
