Amphenol ICC 65863-003 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 65863-003 is a vertical rectangular connector header designed for through-hole mounting applications. This component is classified as obsolete and has been superseded by active product variants. The 65863-003 features a 10-position, 2-row configuration with 0.100" (2.54mm) pitch spacing, shrouded 4-wall design, and solder termination for board-to-cable/wire connections. Due to its obsolete status, equivalent and substitute parts with active product status are available to support ongoing design requirements and procurement needs.

Substitute Part Grouping Explanation

Substitution of the 65863-003 is determined by strict equivalence across the following critical parameters: connector type (header), contact type (male pin), number of positions (10), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole), termination method (solder), shrouding configuration (shrouded 4-wall), contact material (phosphor bronze), contact finish on mating surface (gold or gold GXT™), contact finish thickness on mating surface (30.0µin/0.76µm), contact length specifications, insulation material properties, flammability rating (UL94 V-0), fastening type (push-pull), and keying slot feature.

Substitute parts are grouped into two categories based on these parameters:

Category 1: Direct Electrical and Mechanical Equivalents - Parts that maintain identical or functionally equivalent specifications across all critical parameters, with variations limited to product status (active versus obsolete), RoHS compliance, and post-contact finish specifications where not specified in the original part.

Category 2: Functional Equivalents with Dimensional Variations - Parts that maintain all critical electrical and mechanical parameters but differ in insulation height or insulation material composition while preserving the core connector functionality and mating interface specifications.

Engineering Selection Recommendations

Primary Recommendation for RoHS Compliant Applications:

For applications requiring RoHS compliance, select from the following active parts: 65863-003LF, 65863-367LF, 52601-G10-6LF, 66506-002LF, 66506-110LF. These parts maintain full electrical and mechanical compatibility with the 65863-003 while providing active product status and RoHS compliance certification.

Selection by Insulation Height Requirement:

Parts maintaining the original 0.640" (16.26mm) insulation height are 65863-003LF, 65863-367, and 65863-367LF. These are direct dimensional equivalents to the 65863-003.

Parts with reduced insulation height of 0.365" (9.27mm) are 52601-G10-6LF, 66506-002, 66506-002LF, 66506-049, 66506-110, 66506-110LF, and 66506-119. These parts are functionally equivalent but occupy less vertical space on the PCB.

Selection by Insulation Material:

Parts with thermoplastic insulation material (matching the original 65863-003) are 65863-003LF, 65863-367, and 65863-367LF.

Parts with polyester glass-filled insulation material are 66506-002, 66506-002LF, 66506-049, 66506-110, 66506-110LF, and 66506-119. This material composition provides enhanced mechanical and thermal properties.

Selection by Product Status and Compliance:

All substitute parts listed carry active product status, ensuring long-term availability and supply chain continuity. The 65863-003LF is the direct active equivalent of the obsolete 65863-003, offering identical specifications with RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the 65863-003LF be used as a direct replacement for the obsolete 65863-003?

A: Yes. The 65863-003LF maintains identical electrical and mechanical specifications including connector type, contact configuration, pitch spacing, mounting method, and contact materials. The primary differences are active product status and RoHS compliance. The "LF" designation indicates lead-free post finish, which is compatible with modern solder processes.

Q: What is the difference between parts with 0.640" and 0.365" insulation heights?

A: The insulation height determines the vertical profile of the connector on the PCB. The 0.640" height (65863-003, 65863-003LF, 65863-367, 65863-367LF) provides greater standoff distance from the board surface. The 0.365" height (52601-G10-6LF, 66506 series) reduces overall connector height, which is beneficial for space-constrained applications. Both heights maintain identical mating interface specifications and contact engagement lengths.

Q: Are parts from the 66506 series compatible with the 65863 series?

A: The 66506 series parts are functionally equivalent for mating interface purposes. They share identical contact configuration, pitch spacing, contact materials, and contact finish specifications. The primary differences are insulation material composition (polyester glass-filled versus thermoplastic) and reduced insulation height. Selection between series depends on specific application requirements for insulation material properties and available PCB space.

Q: What does the "LF" suffix indicate?

A: The "LF" suffix designates lead-free post finish, typically tin plating on the solder posts. This specification ensures compatibility with lead-free solder processes and RoHS compliance requirements. Parts without the "LF" designation may have unspecified or non-lead-free post finishes.

Q: Can I substitute a part with polyester glass-filled insulation for one with thermoplastic insulation?

A: Substitution is permissible based on electrical and mechanical compatibility. However, polyester glass-filled insulation provides different mechanical and thermal characteristics compared to thermoplastic. The polyester glass-filled material offers enhanced rigidity and thermal stability. Selection should be based on specific application requirements for insulation material properties, operating environment, and mechanical stress conditions.

Q: Are all substitute parts compatible with the same mating connectors?

A: Yes. All listed substitute parts maintain identical mating interface specifications including contact configuration, pitch spacing (0.100"/2.54mm), row spacing (0.100"/2.54mm), contact length, contact shape, and contact finish. They are fully compatible with the same mating receptacles and cable assemblies designed for the 65863-003.

Q: What is the significance of the 52601-G10-6LF part number in this substitution list?

A: The 52601-G10-6LF is a functionally equivalent alternative from a different base product series. It maintains all critical electrical and mechanical parameters but has a different base product number (52601 versus 65863 or 66506). It features reduced insulation height (0.365") and carries active product status with RoHS compliance. This part is suitable for applications where the reduced profile is advantageous.

Q: Which substitute part should I select for new designs?

A: For new designs requiring RoHS compliance and long-term availability, 65863-003LF is the recommended primary choice as it provides the most direct equivalence to the obsolete 65863-003. For space-constrained applications, 66506-002LF or 66506-110LF offer reduced insulation height with RoHS compliance and active product status. All recommended parts carry active product status and appropriate compliance certifications.
