Amphenol ICC 861400361YO2LF Rectangular Connector Header - Equivalent & Substitute Parts
Part Overview
The Amphenol ICC 861400361YO2LF is an active-status vertical rectangular connector header designed for through-hole board-to-board applications. This 36-position, 0.100" (2.54mm) pitch connector features male pins with gold-plated mating contacts and solder termination. The BERGSTIK® series connector operates across -55°C to 125°C with a 3A current rating and 1000V voltage rating. Substitute parts are identified when original inventory becomes unavailable, when alternative contact finishes or post lengths are required for specific assembly processes, or when different operating temperature ranges or contact materials better suit application requirements.

Substitute Part Grouping Explanation
Substitution eligibility is determined by the following critical parameters: 36-position count, 0.100" (2.54mm) mating pitch, single-row configuration, male pin contact type, through-hole mounting, and solder termination. All substitute parts listed maintain these core specifications. Secondary parameters that differentiate substitutes include contact finish composition (gold vs. tin), contact length dimensions (mating and post lengths), operating temperature range, current rating per contact, contact material (copper alloy vs. phosphor bronze vs. brass), and insulation material composition. Substitute parts are grouped by manufacturer and series, with variations reflecting different contact post lengths, finish specifications, and thermal operating ranges. Parts with identical core specifications but different contact finishes or post lengths are considered direct substitutes for applications where these secondary parameters do not impose functional constraints.

Engineering Selection Recommendations
All listed substitute parts maintain active product status and comply with RoHS requirements. The 3M 961136-6404-AR operates within a reduced temperature range (-25°C to 105°C) and carries a 2A current rating, making it suitable for applications not requiring the full -55°C to 125°C thermal envelope or 3A per-contact capacity of the main part.
Samtec HTS-136-G-AA and HTS-136-T-AA differ primarily in contact finish (gold vs. tin) and are available in tube packaging. Both maintain ROHS3 compliance and unlimited moisture sensitivity rating.
Samtec HTSW-136-07-G-S extends the operating range to -55°C to 125°C, matching the main part's thermal specification, and uses phosphor bronze contacts with liquid crystal polymer insulation. This part is supplied in bulk packaging.
Harwin M20-9773642 and M20-9773646 are cuttable header variants with identical contact dimensions and 3A per-contact ratings. M20-9773642 features gold mating finish with tin post finish, while M20-9773646 uses tin for both mating and post finishes. Both operate across -40°C to 105°C.
Sullins PBC36SAAN, PBC36SABN, PBC36SACN, and PBC36SAEN are breakaway headers with extended operating range (-65°C to 125°C) and phosphor bronze contacts. These parts differ in contact post length: PBC36SAAN (0.120"), PBC36SABN (0.230"), PBC36SACN (0.320"), and PBC36SAEN (0.520"). All carry 3A current rating and gold mating finish with tin post finish.
Frequently Asked Questions (FAQ)
Q: Can I substitute the 861400361YO2LF with any of these parts directly?
A: Direct substitution depends on application-specific requirements. All listed parts share the core specifications: 36 positions, 0.100" (2.54mm) pitch, single row, male pins, through-hole mounting, and solder termination. Verify that contact post length, operating temperature range, current rating, and contact finish meet your assembly and operational requirements before substitution.
Q: What is the primary difference between the Samtec HTS-136-G-AA and HTS-136-T-AA?
A: The primary difference is contact finish. HTS-136-G-AA uses gold mating contact finish, while HTS-136-T-AA uses tin. Both are 36-position headers with 0.100" (2.54mm) pitch and through-hole solder termination. Contact finish selection depends on your application's corrosion resistance and solderability requirements.
Q: Why do the Sullins PBC36 variants have different part numbers if they are all 36-position headers?
A: The Sullins PBC36 series variants differ in contact post length. PBC36SAAN has 0.120" (3.05mm) posts, PBC36SABN has 0.230" (5.84mm) posts, PBC36SACN has 0.320" (8.13mm) posts, and PBC36SAEN has 0.520" (13.21mm) posts. Post length determines how far the contact extends into the PCB, affecting board thickness compatibility and mechanical engagement depth. Select the variant matching your PCB thickness and assembly requirements.
Q: Is the 3M 961136-6404-AR suitable for high-temperature applications?
A: The 3M 961136-6404-AR operates across -25°C to 105°C, which is narrower than the main part's -55°C to 125°C range. It is not suitable for applications requiring operation below -25°C or above 105°C. For extended temperature range requirements, use Samtec HTSW-136-07-G-S, Harwin M20 series, or Sullins PBC36 series variants.
Q: What is the difference between the Harwin M20-9773642 and M20-9773646?
A: Both parts are identical 36-position cuttable headers with 0.100" (2.54mm) pitch and 3A per-contact rating. The difference is contact finish: M20-9773642 has gold mating finish with tin post finish, while M20-9773646 has tin for both mating and post finishes. Select based on your solderability and corrosion resistance requirements.
Q: Can I use the Samtec HTSW-136-07-G-S as a direct replacement for the 861400361YO2LF?
A: The Samtec HTSW-136-07-G-S is compatible for applications requiring the same 36-position, 0.100" (2.54mm) pitch, and -55°C to 125°C operating range. However, verify that the contact post length (0.100" / 2.54mm) and phosphor bronze contact material are acceptable for your PCB thickness and assembly process. The insulation material differs (liquid crystal polymer vs. thermoplastic), which may affect mechanical properties.
Q: What packaging options are available for these substitute parts?
A: The main part 861400361YO2LF is supplied in bulk packaging. Samtec HTS-136-G-AA and HTS-136-T-AA are supplied in tube packaging. All other substitute parts (3M 961136-6404-AR, Samtec HTSW-136-07-G-S, Harwin M20 series, and Sullins PBC36 series) are supplied in bulk packaging. Confirm packaging compatibility with your procurement and assembly processes.
