Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 146252-5 with the Hirose Electric A1-10PA-2.54DSA(71) is based on alignment of the following critical parameters:

Matching Parameters:

• Connector type classification as header with male pin contacts
• 10-position configuration in 2-row arrangement
• 0.100" (2.54mm) mating pitch and row spacing
• Through-hole mounting with solder termination
• Push-pull fastening mechanism
• Unshrouded design
• 3A current rating capability
• Gold-plated mating contacts
• UL94 V-0 flammability rating
• Board-to-board or cable style application

Substitution Basis: The Hirose A1-10PA-2.54DSA(71) maintains functional and mechanical compatibility through identical pitch spacing, position count, mounting methodology, and electrical current specifications. Both connectors employ gold-plated mating surfaces and equivalent insulation material classifications. The substitute part is active in production status, providing continuity for applications previously designed around the obsolete TE Connectivity part.

Parameter Comparison

Engineering Selection Recommendations

The Hirose Electric A1-10PA-2.54DSA(71) serves as the active equivalent for the obsolete TE Connectivity 146252-5. Selection of the Hirose substitute is supported by the following engineering considerations:

Product Status Alignment: The TE Connectivity 146252-5 is classified as obsolete, creating supply chain constraints. The Hirose A1-10PA-2.54DSA(71) maintains active production status, ensuring long-term component availability and supply chain continuity.

Compliance and Certification: The Hirose substitute achieves ROHS3 compliance and REACH unaffected status, providing regulatory advantages over the non-compliant TE Connectivity original. Both connectors maintain UL94 V-0 flammability certification and equivalent ECCN/HTSUS classifications.

Functional Compatibility: Identical pitch spacing (0.100"), position count (10), row configuration (2), mounting methodology (through-hole solder), and current rating (3A) establish direct functional substitution. Both connectors employ gold-plated mating contacts and equivalent insulation material performance classifications.

Mechanical Considerations: Minor dimensional variations exist in contact length and insulation height. The Hirose substitute exhibits slightly reduced overall contact length (0.454" versus 0.533") and increased insulation height (0.100" versus 0.090"). These variations remain within acceptable tolerances for standard board-to-board and cable interconnection applications.

Temperature Operating Range: The TE Connectivity original operates across -65°C to 105°C, while the Hirose substitute operates across -55°C to 85°C. Applications requiring operation below -55°C or above 85°C require evaluation against specific thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A1-10PA-2.54DSA(71) directly replace the TE Connectivity 146252-5 in existing designs?

A: The Hirose substitute maintains mechanical and electrical compatibility through identical pitch spacing, position count, mounting type, and current rating. Direct substitution is supported for standard board-to-board and cable interconnection applications. Design verification is required for applications with specific thermal, dimensional, or compliance requirements.

Q: What are the key differences between these two connector models?

A: Primary differences include product status (obsolete versus active), insulation material composition (LCP versus PBT), contact material (copper alloy versus brass), and operating temperature range (-65°C to 105°C versus -55°C to 85°C). The Hirose substitute provides superior regulatory compliance through ROHS3 certification and REACH unaffected status.

Q: Are there dimensional compatibility concerns when substituting these connectors?

A: Contact length and insulation height dimensions differ slightly. The Hirose substitute exhibits overall contact length of 0.454" compared to 0.533" for the TE Connectivity original, and insulation height of 0.100" compared to 0.090". These variations are within acceptable tolerances for standard through-hole solder applications but require verification for space-constrained designs.

Q: What is the packaging difference between these parts?

A: The TE Connectivity 146252-5 packaging specification is not provided. The Hirose A1-10PA-2.54DSA(71) is supplied in tray packaging. Packaging requirements for production and assembly processes should be confirmed with procurement specifications.

Q: Does the Hirose substitute meet the same compliance standards?

A: Both connectors maintain UL94 V-0 flammability certification and equivalent ECCN/HTSUS classifications. The Hirose substitute provides enhanced compliance through ROHS3 certification and REACH unaffected status, compared to the non-compliant TE Connectivity original.

Q: Are there electrical performance differences between these connectors?

A: Both connectors maintain 3A current rating and gold-plated mating contacts. The Hirose substitute specifies 200V voltage rating, while the TE Connectivity original does not provide voltage specification. Contact finish thickness differs slightly, with the TE Connectivity original providing 15.0µin mating finish compared to 8.00µin for the Hirose substitute.

Q: What applications are suitable for the Hirose A1-10PA-2.54DSA(71) substitute?

A: The Hirose substitute is suitable for board-to-board and cable interconnection applications requiring 10-position, 2-row header connectors with 0.100" pitch spacing and through-hole solder termination. Applications must operate within the -55°C to 85°C temperature range and accommodate the specified dimensional characteristics.
