Amphenol ICC 68418-436 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68418-436 is a vertical through-hole rectangular connector header from the BERGSTIK® II series, designed for board-to-board applications with 36 positions at 0.100" (2.54mm) pitch. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The connector features male pins with tin-plated phosphor bronze contacts, rated for 3A current and operating temperatures from -65°C to 125°C. Direct substitutes and cross-compatible alternatives are available from multiple manufacturers including Amphenol ICC, TE Connectivity, Samtec, and Sullins Connector Solutions.

Substitute Part Grouping Explanation

Substitution eligibility for the 68418-436 is determined by strict alignment with the following critical parameters: 36-position count, 0.100" (2.54mm) mating pitch, male pin contact type, through-hole mounting, solder termination, unshrouded design, and board-to-board or board-to-cable style compatibility. All substitute parts must maintain the same connector footprint and electrical interface characteristics.

The substitute parts are grouped into two categories:

Direct Manufacturer Equivalent (Same Series): The 68418-436HLF is the active production variant of the same BERGSTIK® II series from Amphenol ICC, differing only in packaging (bag vs. bulk) and RoHS compliance status. This part is a direct drop-in replacement with identical electrical and mechanical specifications.

Cross-Manufacturer Substitutes (Compatible Alternatives): Parts from TE Connectivity (8-146274-6), Samtec (HTSW-136-26-TM-S, TSW-136 series variants), and Sullins Connector Solutions (PGC36SAAN) provide functional equivalence through matching core parameters: 36 positions, 2.54mm pitch, male pins, through-hole solder termination, and board-to-board/cable compatibility. These alternatives differ in contact post length, insulation material, contact finish composition, and operating temperature ranges, but remain electrically and mechanically compatible for standard applications.

Engineering Selection Recommendations

Primary Recommendation: 68418-436HLF

The 68418-436HLF is the direct active production equivalent from Amphenol ICC's BERGSTIK® II series. This part provides identical electrical and mechanical specifications to the obsolete 68418-436, with the primary advantage of RoHS compliance and active manufacturing status. Selection of this part eliminates any compatibility risk and maintains design continuity with the original specification.

Secondary Recommendations for Extended Temperature Range:

The TSW-136-09-G-S and TSW-136-11-G-S from Samtec maintain the full -55°C to 125°C operating temperature range of the original part (TSW-136-09-G-S) or extend to -55°C to 125°C (TSW-136-11-G-S). Both are ROHS3 compliant and feature gold-plated contacts. The primary difference between these variants is contact post length: TSW-136-09-G-S provides 0.400" (10.16mm) post length matching the original, while TSW-136-11-G-S provides 0.600" (15.24mm) for applications requiring deeper board penetration.

Alternative for Compact PCB Designs:

The TE Connectivity 8-146274-6 (AMPMODU Mod II series) and Samtec HTSW-136-26-TM-S offer reduced contact post lengths (0.125" and 0.126" respectively), suitable for applications with space constraints or thinner PCB assemblies. Both maintain the 36-position, 2.54mm pitch configuration and through-hole solder termination. The TE part operates to 105°C maximum, while the Samtec HTSW variant operates to 105°C with ROHS3 compliance.

Gold-Plated Contact Alternative:

The Sullins Connector Solutions PGC36SAAN provides gold-plated mating and post contacts (10.0µin and 5.00µin thickness respectively), offering enhanced corrosion resistance compared to tin-plated alternatives. This part is ROHS3 compliant and rated for 3A current. Operating temperature range is not specified in the provided data.

Considerations for Temperature-Critical Applications:

Applications requiring the full -65°C to 125°C operating range of the original 68418-436 are best served by the 68418-436HLF (identical range) or TSW-136-09-G-S (−55°C to 125°C). The TE Connectivity 8-146274-6 and Samtec HTSW-136-26-TM-S are limited to 105°C maximum, making them unsuitable for high-temperature applications exceeding this threshold.

Frequently Asked Questions (FAQ)

Q: Can I use 68418-436HLF as a direct replacement for the obsolete 68418-436?

A: Yes. The 68418-436HLF is the active production equivalent from the same BERGSTIK® II series with identical electrical and mechanical specifications. The only differences are packaging format (bag vs. bulk) and RoHS compliance status. This is the recommended direct replacement.

Q: What is the primary difference between the Samtec TSW-136 variants (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S)?

A: The TSW-136 series variants differ in contact post length. TSW-136-09-G-S provides 0.400" (10.16mm) post length, TSW-136-10-G-S provides 0.500" (12.70mm), and TSW-136-11-G-S provides 0.600" (15.24mm). All maintain the same 0.230" (5.84mm) mating contact length and 36-position 2.54mm pitch configuration. Post length selection depends on PCB thickness and application requirements.

Q: Are gold-plated contacts (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, PGC36SAAN) compatible with tin-plated receptacles designed for the original 68418-436?

A: Gold-plated contacts are compatible with tin-plated receptacles. The gold plating provides enhanced corrosion resistance and contact reliability. No design changes are required when substituting gold-plated headers for tin-plated alternatives in existing receptacle designs.

Q: What is the operating temperature limitation when using TE Connectivity 8-146274-6 or Samtec HTSW-136-26-TM-S?

A: Both parts are rated to 105°C maximum operating temperature, compared to the original 68418-436 specification of 125°C. These parts are not suitable for applications requiring operation above 105°C. For full temperature range compatibility, use 68418-436HLF or TSW-136-09-G-S (-55°C to 125°C).

Q: Does the reduced contact post length of the TE Connectivity 8-146274-6 (0.125") affect compatibility with standard PCB thicknesses?

A: The 0.125" (3.18mm) post length of the 8-146274-6 is suitable for standard PCB thicknesses of 0.062" (1.57mm). For thicker PCBs or applications requiring deeper solder joint penetration, select alternatives with longer post lengths such as TSW-136-09-G-S (0.400"), TSW-136-10-G-S (0.500"), or TSW-136-11-G-S (0.600").

Q: Is the Sullins PGC36SAAN suitable for high-reliability applications?

A: The PGC36SAAN is ROHS3 compliant with UL94 V-0 flammability rating and gold-plated contacts, meeting standard high-reliability requirements. However, operating temperature range is not specified in the provided data. Confirm temperature specifications with the manufacturer before selection for temperature-critical applications.

Q: What is the difference between ROHS compliant and ROHS3 compliant parts?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the part meets the original directive restricting lead and other hazardous substances. ROHS3 compliance indicates the part meets the updated RoHS 3 directive (2011/65/EU as amended by 2015/863/EU), which includes additional restricted substances. ROHS3 compliant parts meet current regulatory requirements for EU and many international markets.

Q: Can I mix different substitute parts (e.g., some TSW-136-09-G-S and some 68418-436HLF) in the same assembly?

A: Yes, all substitute parts listed maintain the same 36-position, 2.54mm pitch, male pin configuration and through-hole solder termination. Mixing different manufacturers and variants in the same assembly is electrically and mechanically compatible. However, for manufacturing consistency and traceability, using a single part number per assembly is recommended.
