Amphenol ICC 86503-172 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 86503-172 is a rectangular connector header featuring 72 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. This through-hole solder-terminated connector is designed for board-to-board applications and is classified as Active product status. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when alternative compliance certifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 86503-172 are qualified based on the following critical parameters that determine functional equivalence:

• Connector positioning and pitch: 72 positions, 2 rows, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing
• Contact configuration: Male pin contacts with square or circular contact shape
• Mounting and termination: Through-hole solder termination with push-pull fastening
• Board interface style: Board-to-board connectivity
• Environmental compliance: UL94 V-0 flammability rating and MSL 1 classification

The identified substitutes—TE Connectivity 3-826632-6, TE Connectivity 3-826925-6, Samtec BBD-136-G-B, and Samtec BBD-136-T-B—meet these core electrical and mechanical requirements. Variations in contact finish, insulation material, contact length, and operating temperature ranges do not prevent functional substitution when application constraints permit.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status, ensuring long-term availability and manufacturer support. The TE Connectivity parts (3-826632-6 and 3-826925-6) provide ROHS3 compliance, addressing regulatory requirements that may supersede the original part's non-compliant status. The Samtec alternatives (BBD-136-G-B and BBD-136-T-B) offer extended operating temperature range (-55°C to 125°C versus -65°C to 105°C for TE parts) and ROHS3 compliance, suitable for applications requiring broader thermal performance.

Selection between TE Connectivity and Samtec options depends on contact finish requirements and insulation material compatibility. TE Connectivity parts utilize PBT insulation with specified current ratings (5A), while Samtec parts employ glass-filled polyester insulation with extended temperature capability. Contact shape differences (square for TE, circular for Samtec) may influence mating force and contact resistance characteristics in specific applications.

Frequently Asked Questions (FAQ)

Q: Can the 86503-172 be directly replaced with TE Connectivity 3-826632-6 or 3-826925-6?

A: Yes. Both TE Connectivity parts maintain identical pitch spacing (0.100"), position count (72 in 2 rows), contact type (male pin), mounting method (through-hole solder), and fastening mechanism (push-pull). Functional compatibility is established. Differences in contact finish, insulation material, and operating temperature range do not prevent substitution when application parameters fall within the substitute part's specifications.

Q: What are the differences between the TE Connectivity and Samtec substitute options?

A: TE Connectivity parts (3-826632-6, 3-826925-6) feature square contact geometry, PBT insulation, and operating range of -65°C to 105°C with 5A current rating. Samtec parts (BBD-136-G-B, BBD-136-T-B) feature circular contact geometry, glass-filled polyester insulation, and extended operating range of -55°C to 125°C. Contact finish options vary: TE offers gold or tin finishes; Samtec offers gold (BBD-136-G-B) or tin (BBD-136-T-B) finishes.

Q: Does the 86503-172's RoHS non-compliant status affect substitute selection?

A: All substitute parts are ROHS3 compliant, providing regulatory advantage for new designs or applications with RoHS requirements. If the original design was validated with the 86503-172 under non-compliant conditions, substitution with RoHS-compliant alternatives may require design review to confirm material composition compatibility.

Q: Are packaging differences between Bulk (86503-172, TE parts) and Tube (Samtec parts) significant?

A: Packaging differences affect handling, storage, and procurement logistics but do not impact electrical or mechanical performance. Bulk packaging typically suits high-volume assembly operations, while tube packaging accommodates lower-volume or manual assembly processes. Component specifications remain identical regardless of packaging format.

Q: Which substitute part is recommended for high-temperature applications?

A: Samtec BBD-136-G-B and BBD-136-T-B are rated for -55°C to 125°C operation, providing 20°C higher maximum temperature than TE Connectivity alternatives (-65°C to 105°C). Selection depends on specific application temperature requirements and contact finish preferences (gold or tin).
