Engineering Selection Recommendations

TE Connectivity 1-87227-7 (Primary Part)

The TE Connectivity 1-87227-7 is Active status and RoHS Compliant. This part features an extended operating temperature range of -65°C to 105°C, making it suitable for applications requiring low-temperature performance. The AMPMODU Mod II series provides established design heritage and broad industry recognition. Current inventory of 1,214 pieces supports immediate availability.

Hirose Electric A1-34PA-2.54DSA(71) (Substitute)

The Hirose A1-34PA-2.54DSA(71) is Active status and RoHS Compliant. This part operates within -55°C to 85°C, which is narrower than the primary part. Applications limited to this temperature range can utilize this substitute. The A1 series offers compatibility with the same 34-position, 2.54mm pitch configuration. Inventory of 692 pieces is available in tray packaging.

Harwin M20-9761746 (Substitute)

The Harwin M20-9761746 is Active status and ROHS3 Compliant. This cuttable header variant operates from -40°C to 105°C and supports the full upper temperature range of the primary part. The M20 series provides configurable mated stacking heights (9.94mm, 10.64mm, 11.04mm, 16.54mm). Inventory of 2,968 pieces is available in bulk packaging.

Harwin M20-9981746 (Substitute)

The Harwin M20-9981746 is Active status and ROHS3 Compliant. This cuttable header variant operates from -40°C to 105°C and supports the full upper temperature range of the primary part. The M20 series provides configurable mated stacking heights (9.94mm, 10.64mm, 11.04mm, 16.54mm). Inventory of 1,868 pieces is available in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A1-34PA-2.54DSA(71) be used in applications requiring operation below -55°C?

A: No. The Hirose A1-34PA-2.54DSA(71) operates from -55°C to 85°C. Applications requiring operation at -65°C must use the TE Connectivity 1-87227-7 or Harwin M20 series parts, which support -40°C minimum or lower.

Q: What is the difference between the Harwin M20-9761746 and M20-9981746?

A: Both parts are cuttable headers in the M20 series with identical electrical specifications and operating temperature range (-40°C to 105°C). The primary difference is contact length: M20-9761746 has mating contact length of 0.228" (5.80mm), while M20-9981746 has 0.240" (6.10mm). Overall contact length differs accordingly (0.452" versus 0.460"). Selection depends on specific board thickness and mating depth requirements.

Q: Are all substitute parts available in the same packaging as the primary TE Connectivity part?

A: No. The TE Connectivity 1-87227-7 is supplied in bulk packaging. The Hirose A1-34PA-2.54DSA(71) is supplied in tray packaging. Both Harwin M20 parts are supplied in bulk packaging. Packaging format may affect handling, storage, and integration into assembly processes.

Q: Do the Harwin M20 series parts support the same mated stacking heights as the TE Connectivity part?

A: The TE Connectivity 1-87227-7 does not specify mated stacking heights. The Harwin M20-9761746 and M20-9981746 provide configurable mated stacking heights of 9.94mm, 10.64mm, 11.04mm, and 16.54mm. Applications requiring specific stacking heights should reference the Harwin parts' mechanical specifications.

Q: Are all parts RoHS compliant?

A: Yes. The TE Connectivity 1-87227-7 is RoHS Compliant. The Hirose A1-34PA-2.54DSA(71) is RoHS Compliant. Both Harwin M20 parts are ROHS3 Compliant. All parts meet RoHS requirements for current production designs.

Q: What is the significance of the "Cuttable" designation on Harwin M20 parts?

A: The Harwin M20-9761746 and M20-9981746 are designated as cuttable headers, indicating the connector can be cut to reduce the number of positions if required. The TE Connectivity 1-87227-7 and Hirose A1-34PA-2.54DSA(71) are not cuttable and must be used as complete 34-position assemblies.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability depends on application-specific requirements including operating temperature range, packaging format, mechanical stacking height, and board layout. All parts share identical pitch (0.100"/2.54mm), position count (34), row configuration (2), and contact type (male pin). Designs operating within -55°C to 85°C can use any substitute. Designs requiring -65°C operation must use the TE Connectivity 1-87227-7. Designs requiring specific stacking heights should reference Harwin M20 specifications.
