Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Position Count & Pitch: All substitutes maintain 14 positions at 0.100" (2.54mm) mating pitch with 2-row configuration
Connector Type & Contact Type: All substitutes are male pin headers with push-pull fastening
Shrouding & Mounting: All substitutes feature shrouded 4-wall design with through-hole mounting and solder termination
Electrical Characteristics: All substitutes maintain UL94 V-0 flammability rating and MSL 1 classification
Contact Geometry: All substitutes use square contact shape with gold mating surface finish

Substitutes are grouped by manufacturer and series. Variations in contact length, insulation height, contact material, and post finish do not preclude substitution when mating interface dimensions remain compatible.

Engineering Selection Recommendations

Primary Recommendation: 52601-S14-4LF (Amphenol ICC)

This part is the optimal substitute based on active product status, full RoHS compliance, and electrical parameter alignment. The 52601-S14-4LF maintains identical position count, pitch, row spacing, and shrouding configuration. Contact finish thickness at the mating surface (15.0µin) matches the original specification, ensuring equivalent signal integrity and contact resistance characteristics.

Secondary Recommendation: 66506-068LF (Amphenol ICC)

This part provides an alternative with active status and RoHS compliance. The 66506-068LF is suitable for board-to-cable/wire applications and maintains all critical mating interface parameters. The increased contact finish thickness (30.0µin) provides enhanced durability for high-cycle mating applications.

Alternative: 008383014000010 (KYOCERA AVX)

This part offers active status and ROHS3 compliance with minimal dimensional variation. The contact length at mating (0.242") is within 0.001" of the original specification. This part is suitable for applications where KYOCERA AVX supply chain integration is preferred.

Non-Recommended: 66506-068 (Amphenol ICC)

Although electrically compatible, this part retains RoHS non-compliant status, limiting its use in new designs subject to regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different contact post length?

A: Contact post length variation does not affect mating compatibility. Post length determines PCB insertion depth and solder joint geometry. Substitutes with post lengths ranging from 0.105" to 0.150" are mechanically compatible with standard PCB through-hole patterns designed for 0.100" to 0.125" post insertion. Verify PCB pad layout accommodates the selected post length.

Q: What is the difference between board-to-board and board-to-cable/wire style designations?

A: This designation indicates the intended mating connector type. Board-to-board headers mate with receptacle connectors on another PCB. Board-to-cable/wire headers mate with wire-terminated connectors. Both styles use identical mating interface geometry and are mechanically interchangeable. Selection depends on the mating connector type in your application.

Q: Does contact material (copper alloy vs. phosphor bronze vs. brass) affect substitution eligibility?

A: Contact material affects mechanical durability and spring characteristics but does not affect electrical compatibility for standard signal applications. All materials specified maintain adequate conductivity and contact resistance. Material selection impacts mating cycle life and force requirements. Phosphor bronze provides superior spring properties for high-cycle applications.

Q: Are there compliance differences between RoHS Compliant and ROHS3 Compliant parts?

A: ROHS3 Compliant indicates compliance with the most current RoHS 3 directive (2015/863/EU), which includes restrictions on phthalates. RoHS Compliant indicates compliance with earlier RoHS directives. For new designs, ROHS3 Compliant parts are preferred. Both designations indicate lead-free construction.

Q: Can I substitute a part with higher contact finish thickness?

A: Yes. Increased contact finish thickness (30.0µin vs. 15.0µin) provides enhanced corrosion resistance and extended mating life without affecting electrical performance. This is a beneficial substitution for applications requiring extended service life or harsh environmental exposure.

Q: What packaging options are available?

A: Substitute parts are available in Tray and Bulk packaging. Tray packaging is standard for production quantities. Bulk packaging is available for high-volume applications. Packaging does not affect component performance or compatibility.
