Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: A3B-28PA-2DS(51)

The A3B-28PA-2DS(51) is the direct Hirose Electric equivalent with active product status. It maintains identical mechanical and electrical specifications to the obsolete A3B-28PA-2DS(71) with the exception of increased current rating (2A versus 1A) and ROHS3 compliance certification. This part provides the highest compatibility with existing designs and procurement processes.

Secondary Recommendations: Amphenol ICC (FCI) Minitek® Series

The 10072353-F01-14ULF, 10072353-G01-14ULF, 58102-G61-14LF, 58102-S61-14, 58102-G61-14, and 98423-F61-14ULF parts from Amphenol ICC maintain all core mechanical and electrical parameters. These parts feature copper alloy contacts and thermoplastic insulation materials. The -F01 and -G01 variants offer 3A current rating. The 58102 series variants provide 2A current rating. RoHS compliance status varies; select 58102-G61-14LF or 98423-F61-14ULF for RoHS-compliant designs.

Tertiary Recommendations: 3M and Samtec Options

The 951228-7622-AR (3M) provides RoHS compliance and extended operating temperature range (-55°C to 125°C) with 1A current rating. The TMMH-114-01-G-D-RA and TMMH-114-01-G-D-RA-006 (Samtec) are cuttable header strips with ROHS3 compliance and extended temperature range. The TMMH-114-01-G-D-RA-006 variant has 27 positions loaded versus 28 for the main part and should be evaluated for application-specific requirements.

Compliance Considerations:

For new designs requiring RoHS compliance, select from: A3B-28PA-2DS(51), 10072353-F01-14ULF, 10072353-G01-14ULF, 58102-G61-14LF, 98423-F61-14ULF, 951228-7622-AR, TMMH-114-01-G-D-RA, or TMMH-114-01-G-D-RA-006.

For legacy applications without RoHS requirements, 58102-G61-14 and 58102-S61-14 remain available.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher current rating than the original A3B-28PA-2DS(71)?

A: Yes. The A3B-28PA-2DS(71) is rated for 1A. Substitute parts rated for 2A or 3A provide design margin and are electrically compatible. The higher current rating does not affect compatibility with existing circuit designs operating at or below 1A.

Q: What is the difference between the Amphenol ICC Minitek® variants (10072353-F01-14ULF, 10072353-G01-14ULF, 58102-G61-14, 58102-G61-14LF, 58102-S61-14)?

A: These parts share identical mechanical dimensions and pitch but differ in contact finish specifications and RoHS compliance. The 10072353 series offers 3A current rating. The 58102 series offers 2A current rating. The -G61-14LF and 98423-F61-14ULF variants are RoHS compliant. The -G61-14 and -S61-14 variants are RoHS non-compliant. Contact finish variations (GXT™ versus Flash) do not affect electrical performance.

Q: Are the Samtec TMMH-114 parts direct replacements?

A: The TMMH-114-01-G-D-RA and TMMH-114-01-G-D-RA-006 are cuttable header strips with identical pitch and row configuration. The TMMH-114-01-G-D-RA-006 has 27 positions loaded instead of 28. Both feature extended operating temperature range (-55°C to 125°C) and ROHS3 compliance. Verify application requirements for position count before selection.

Q: What packaging options are available?

A: Substitute parts are available in Bulk, Tube, and unspecified packaging. The A3B-28PA-2DS(51) is supplied in Bulk. Amphenol ICC Minitek® parts are supplied in Bulk or Tube. Samtec TMMH parts have unspecified packaging. Confirm packaging requirements with procurement specifications.

Q: Which substitute part has the best inventory availability?

A: The 10072353-G01-14ULF has the highest inventory at 1126 pieces, followed by the TMMH-114-01-G-D-RA-006 at 935 pieces and A3B-28PA-2DS(51) at 1059 pieces. All substitute parts maintain active stock status.

Q: Can I mix substitute parts in the same design?

A: All listed substitute parts maintain identical mechanical and electrical core parameters (pitch, position count, row spacing, voltage rating, fastening type). They are mechanically and electrically interchangeable. However, maintain consistency within a single assembly for manufacturing and quality control purposes.

Q: What is the difference between the 3M 951228-7622-AR and the Hirose A3B-28PA-2DS(51)?

A: Both are 1A-rated headers with identical pitch and position count. The 951228-7622-AR features extended operating temperature range (-55°C to 125°C versus -55°C to 85°C) and copper alloy contacts. The A3B-28PA-2DS(51) maintains the original Hirose design with brass contacts and ROHS3 compliance. Select based on temperature requirements and design continuity preferences.
