Amphenol ICC 68032-136H Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68032-136H is a through-hole rectangular connector header featuring 36 positions at 0.100" (2.54mm) pitch. This unshrouded, board-to-board header utilizes phosphor bronze male pins with gold or GXT™ contact finish and is part of the BERGSTIK® II series. The connector is actively produced and stocked at 1,059 units.

Engineering Selection Recommendations

Primary Substitute - TE Connectivity 8-146274-6: This part maintains core mechanical compatibility with 36 positions at 0.100" pitch and through-hole solder termination. It achieves RoHS compliance and offers extended operating temperature range (-65°C to 105°C). The insulation height deviation (0.090" vs. 0.100") and contact length at mating interface (0.318" vs. 0.230") represent dimensional differences that require board-level verification before deployment. Tin contact finish provides cost efficiency for non-corrosive environments.

Samtec TSW Series Substitutes: The TSW-136 family (TSW-136-09-G-S, TSW-136-09-T-S, TSW-136-10-G-S, TSW-136-10-T-S, TSW-136-11-G-S, TSW-136-22-T-S, TSW-136-23-SM-S) maintains exact mating contact geometry (0.230" length) and insulation height (0.100"), ensuring direct mechanical compatibility. All variants are ROHS3 compliant and actively produced. Selection within this family depends on post length requirements and contact finish specification:

Gold-finished variants (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S): Support extended operating temperature to 125°C with 10.0µin gold plating
Tin-finished variants (TSW-136-09-T-S, TSW-136-10-T-S, TSW-136-22-T-S): Operate to 105°C maximum
Post length selection: TSW-136-09 (0.400"), TSW-136-10 (0.500"), TSW-136-11 (0.600"), TSW-136-22 (0.300"), TSW-136-23-SM-S (0.115") accommodate varying PCB stack-up depths

All Samtec alternatives feature phosphor bronze contacts with PBT insulation and UL94 V-0 flammability rating, matching the primary part's core electrical and safety specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 8-146274-6 be used as a direct drop-in replacement for the 68032-136H?

A: The 8-146274-6 shares the same 36-position, 0.100" pitch configuration and through-hole solder termination. However, the insulation height is 0.090" versus 0.100", and the mating contact length is 0.318" versus 0.230". These dimensional differences require verification against your receptacle design and PCB layout before implementation.

Q: What is the primary difference between Samtec TSW-136 variants?

A: All TSW-136 variants maintain identical mating contact geometry (0.230" length) and insulation height (0.100"), ensuring mechanical compatibility with the 68032-136H. Variants differ in post length (ranging from 0.115" to 0.600"), contact finish (gold or tin), and maximum operating temperature (105°C or 125°C). Select the variant matching your PCB thickness and thermal requirements.

Q: Are all substitute parts RoHS compliant?

A: The primary part (68032-136H) is RoHS non-compliant. All listed substitutes are RoHS compliant (TE Connectivity 8-146274-6 is RoHS Compliant; Samtec TSW series are ROHS3 Compliant). If RoHS compliance is a design requirement, any substitute part satisfies this criterion.

Q: Which substitute offers the closest electrical and thermal performance to the original part?

A: The Samtec TSW-136-09-G-S and TSW-136-23-SM-S provide the closest match in contact geometry and material composition. TSW-136-09-G-S extends operating temperature to 125°C with gold plating matching the original's contact finish specification. TSW-136-23-SM-S offers the shortest post length (0.115") for shallow PCB applications while maintaining gold mating finish at 30.0µin thickness, identical to the 68032-136H specification.

Q: Can I mix post lengths within the same assembly?

A: Post length is a connector-specific parameter determined during manufacturing. Individual connectors within a single part number maintain uniform post length. If your design requires multiple post lengths, order separate part numbers for each depth requirement.

Q: What is the significance of contact finish thickness specifications?

A: Contact finish thickness affects durability and mating cycle life. The 68032-136H specifies 30.0µin (0.76µm) gold plating. Samtec TSW-136 gold variants use 10.0µin (0.25µm) plating, which is thinner but remains within industry standards for 0.100" pitch headers. TE Connectivity 8-146274-6 uses 100.0µin (2.54µm) tin plating, providing enhanced corrosion resistance in humid environments.

Q: Are Samtec TSW-136 connectors breakaway-capable like the TE Connectivity part?

A: The TE Connectivity 8-146274-6 is specified as "Header, Breakaway," indicating individual positions can be separated. Samtec TSW-136 variants are specified as "Header" without breakaway designation. Verify breakaway capability requirements against your assembly process before substitution.
