3M 953228-2000-AR-TP Equivalent & Substitute Parts

Part Overview

The 3M 953228-2000-AR-TP is a 28-position rectangular receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount board-to-board applications. This connector features gold-plated mating contacts, push-pull fastening, and operates across -40°C to 105°C. The part is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain electrical and mechanical compatibility for new designs or production continuity.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Connector Configuration: 28 positions, 2 rows, 0.079" (2.00mm) pitch and row spacing
Mounting & Termination: Surface mount with solder termination
Contact System: Female socket, gold-plated mating surface, push-pull fastening
Electrical Performance: Current and voltage ratings must meet or exceed the original specification
Environmental Compliance: UL94 V-0 flammability rating and MSL 1 classification

The substitute parts listed below satisfy these core parameters. Variations in insulation height, contact material composition, and specific feature implementations (such as board guides or pick-and-place provisions) do not preclude substitution when electrical and mechanical interfaces remain compatible.

Engineering Selection Recommendations

All listed substitute parts maintain mechanical and electrical interface compatibility with the 3M 953228-2000-AR-TP through identical connector geometry, pitch, row configuration, and contact system. Selection among substitutes should be based on the following criteria:

Active Product Status: All substitute parts carry active product status, ensuring long-term availability and manufacturing support. The original 3M part is obsolete and no longer recommended for new designs.

Compliance & Certifications: Hirose A3-28DA-2SV(71), Hirose A3A-28DA-2SV(71), and all Samtec SMM-114 variants carry ROHS3 compliance certification. Molex 0873812818 does not specify flammability rating; applications requiring UL94 V-0 certification should prioritize Hirose or Samtec alternatives.

Electrical Performance: Samtec SMM-114 series connectors provide superior current capacity (3.2A per contact) and voltage rating (350VAC) compared to the original specification. Hirose A3 series maintains the original 1A current rating. Molex 0873812818 offers intermediate performance (1.9A, 125V).

Temperature Range: Samtec SMM-114 series supports -55°C to 125°C, exceeding the original -40°C to 105°C range. Hirose A3 series operates to 85°C maximum, which is below the original upper limit of 105°C and may not be suitable for applications requiring the full original temperature envelope.

Packaging Variants: Samtec offers multiple packaging options including Tape & Reel (TR) for automated assembly, standard tube packaging, and variants with pick-and-place features (SMM-114-02-F-D-P, SMM-114-02-F-D-P-TR) or board lock provisions (SMM-114-02-F-D-LC). Select packaging based on assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A3-28DA-2SV(71) be used as a direct replacement in applications requiring operation to 105°C?

A: No. The Hirose A3-28DA-2SV(71) maximum operating temperature is 85°C, which does not meet the original specification of -40°C to 105°C. Applications requiring the full temperature range should use Samtec SMM-114 series connectors, which operate to 125°C.

Q: What is the difference between Samtec SMM-114-02-F-D and SMM-114-02-F-D-K?

A: Both connectors are electrically and mechanically identical. The SMM-114-02-F-D-K variant includes a pick-and-place feature for automated assembly processes. Select based on manufacturing requirements.

Q: Does the Molex 0873812818 meet the original voltage specification of 1000VDC?

A: No. The Molex 0873812818 is rated for 125V, which is significantly below the original 1000VDC specification. This part is suitable only for applications with lower voltage requirements.

Q: Are all substitute parts compatible with the same mating connector?

A: All substitute parts maintain the same 28-position, 0.079" (2.00mm) pitch, 2-row configuration as the original 3M connector. Mating connectors designed for the 3M 953228-2000-AR-TP will mate with all listed substitutes.

Q: Which substitute offers the best performance upgrade?

A: Samtec SMM-114 series connectors provide the highest current capacity (3.2A per contact), voltage rating (350VAC), and operating temperature range (-55°C to 125°C). These connectors are suitable for demanding applications requiring enhanced electrical performance.

Q: What packaging options are available for high-volume production?

A: Samtec SMM-114-02-F-D-P-TR and SMM-114-02-FM-D-TR are supplied in Tape & Reel packaging with pick-and-place features, optimized for automated surface mount assembly. Standard tube packaging is available for all variants.

Q: Is the Hirose A3A-28DA-2SV(71) different from the A3-28DA-2SV(71)?

A: The A3A-28DA-2SV(71) includes a board guide feature for improved alignment during assembly. Both variants are electrically and mechanically equivalent and share the same 85°C maximum operating temperature limitation.
