Amphenol ICC 50003-1040F Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1040F is a 40-position high-density backplane connector receptacle with female sockets, designed for through-hole, right-angle PCB mounting. This connector features a 0.100" (2.54mm) pitch configuration arranged in 4 rows by 10 columns, with gold-plated contacts and a mating guide. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1040F is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets; High Density)
• Position count and pitch (40 positions at 0.100" spacing)
• Physical configuration (4 rows × 10 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact material and finish (Gold plating)
• Series compatibility (HPC™ series)

The substitute part 50003-1040FLF meets all these criteria. The primary distinction is product status: the original part is obsolete, while the substitute is active in production with RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1040FLF is the direct functional equivalent of the 50003-1040F. Both parts share identical electrical and mechanical specifications within the HPC™ series. The substitute part offers the advantage of active production status and RoHS compliance certification, making it suitable for new designs and legacy system replacements where the original part is no longer available.

Selection between these parts should be based on availability and regulatory requirements. The 50003-1040FLF is recommended for applications requiring RoHS compliance or where long-term supply continuity is a consideration.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1040FLF be used as a direct replacement for the 50003-1040F?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting configuration, and contact specifications. The substitute part maintains full electrical and mechanical compatibility.

Q: What is the significance of the "FLF" suffix in the part number 50003-1040FLF?

A: The suffix indicates RoHS compliance and active production status. The base part number 50003-1040 remains consistent, with the suffix denoting material and regulatory compliance variations.

Q: Are there any differences in PCB footprint or mounting hole patterns?

A: No. Both parts share identical through-hole, right-angle mounting specifications and will use the same PCB footprint.

Q: Why is the original 50003-1040F listed as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation of a product line. The 50003-1040FLF represents the current production equivalent within the same HPC™ series.

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and supply-chain consideration rather than a functional requirement. The 50003-1040FLF's RoHS status makes it preferable for applications subject to RoHS regulations or for organizations with RoHS-compliant procurement policies.
