Equivalent & Substitute Parts for 86503-472H

Part Overview

The Amphenol ICC 86503-472H is a rectangular connector header featuring 72 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. This through-hole, board-to-board connector utilizes male pins with solder termination and push-pull fastening. The part is currently active in production with 701 units in stock. Substitute parts are necessary to address supply chain flexibility, alternative compliance certifications, contact finish specifications, and packaging preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 86503-472H is determined by strict alignment with the following core parameters: 72-position count, 2-row configuration, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, through-hole mounting, solder termination, push-pull fastening, board-to-board style, unshrouded design, and UL94 V-0 flammability rating.

The three qualified substitute parts—TE Connectivity 3-826632-6, Samtec BBD-136-G-B, and Samtec BBD-136-T-B—meet all mandatory electrical and mechanical parameters. Variations in contact finish (tin, gold), contact material (phosphor bronze, brass), insulation material composition, operating temperature ranges, and packaging format (bulk versus tube) do not disqualify substitution but represent design trade-offs for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full electrical and mechanical compatibility with the 86503-472H based on core connector specifications. Selection between alternatives depends on specific compliance and operational requirements:

TE Connectivity 3-826632-6 is ROHS3 compliant and offers gold-plated mating contacts with an extended operating temperature range of -65°C to 105°C. The breakaway connector feature provides additional design flexibility for board-to-board or cable applications. This part is recommended for applications requiring enhanced RoHS compliance and superior contact reliability through gold plating.

Samtec BBD-136-G-B provides gold-plated mating contacts with the widest operating temperature range (-55°C to 125°C) and ROHS3 compliance. Tube packaging is suitable for automated assembly environments. This part is recommended for high-temperature applications and environments where tube packaging is preferred.

Samtec BBD-136-T-B matches the tin contact finish of the original 86503-472H while offering ROHS3 compliance and the same extended operating temperature range as BBD-136-G-B (-55°C to 125°C). Tube packaging supports automated handling. This part is recommended for applications requiring tin-plated contacts with modern RoHS compliance and high-temperature operation.

Frequently Asked Questions (FAQ)

Q: Can the 86503-472H be directly replaced with any of these substitute parts?

A: Yes. All three substitute parts maintain the critical electrical and mechanical parameters: 72 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole solder termination, and push-pull fastening. Physical and electrical interchangeability is confirmed.

Q: What is the primary difference between the TE Connectivity 3-826632-6 and the Samtec options?

A: The TE Connectivity part features a breakaway connector design, allowing it to function in both board-to-board and cable applications. The Samtec parts are fixed board-to-board headers. Contact finish and operating temperature ranges also differ.

Q: Why do the Samtec parts have different contact finishes (gold versus tin)?

A: BBD-136-G-B uses gold plating for enhanced corrosion resistance and contact reliability in demanding environments. BBD-136-T-B uses tin plating, matching the original 86503-472H specification. Selection depends on application requirements and cost considerations.

Q: Does packaging format affect electrical performance?

A: No. Bulk and tube packaging formats do not affect electrical or mechanical performance. Packaging selection is driven by assembly process requirements and inventory management preferences.

Q: Are all substitute parts RoHS compliant?

A: The original 86503-472H is RoHS non-compliant. All three substitute parts are ROHS3 compliant, making them suitable for applications with RoHS requirements.

Q: What operating temperature range should I use for the 86503-472H?

A: The original part does not specify an operating temperature range. If temperature performance is critical, substitute parts with defined ranges (-65°C to 105°C for TE Connectivity, -55°C to 125°C for Samtec) are recommended.
