Substitute Part Grouping Explanation

Substitution of the 3M 953226-2000-AR-TP is determined by the following critical parameters that must remain constant:

26-position configuration with 2-row layout
0.079" (2.00mm) mating pitch and row spacing
Surface mount termination with solder connection
Female socket contact type
Push-pull fastening mechanism
Gold-plated mating contact finish
Black insulation color
Square contact shape
UL94 V-0 flammability rating
MSL 1 (Unlimited) moisture sensitivity

The Samtec Tiger Eye™ SMM series receptacles meet these core requirements. Variations within the SMM-113-02 family accommodate different packaging formats (Tube, Tape & Reel), contact finish specifications, and optional features (Pick and Place, Board Lock) without affecting core electrical and mechanical compatibility.

Engineering Selection Recommendations

All Samtec Tiger Eye™ SMM-113-02 variants listed are active products with ROHS3 compliance (where specified) and maintain the core mechanical and electrical interface compatibility with the 3M 953226-2000-AR-TP. Selection among variants depends on production requirements:

SMM-113-02-F-D and SMM-113-02-F-D-TR serve as primary direct replacements, with the TR variant providing tape and reel packaging for automated assembly.

SMM-113-02-F-D-K and SMM-113-02-F-D-K-TR include pick-and-place features, beneficial for high-volume surface mount production.

SMM-113-02-F-D-LC and SMM-113-02-L-D-LC-P incorporate board lock mechanisms for enhanced mechanical retention.

SMM-113-02-H-D and SMM-113-02-H-D-TR feature gold plating on both mating and post contacts, providing enhanced corrosion resistance compared to tin-plated post finishes.

SMM-113-02-FM-D offers an alternative contact configuration within the same footprint and electrical interface.

All substitutes maintain UL94 V-0 flammability compliance and MSL 1 moisture sensitivity rating. The extended operating temperature range (-55°C to 125°C) of Samtec parts exceeds the original specification, providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Are all SMM-113-02 variants mechanically interchangeable with the 3M 953226-2000-AR-TP?

A: Yes. All listed variants maintain identical 26-position configuration, 0.079" (2.00mm) pitch, 2-row layout, and surface mount footprint. Differences in packaging format (Tube vs. Tape & Reel) and optional features (Pick and Place, Board Lock) do not affect PCB-level compatibility.

Q: What is the difference between SMM-113-02-F-D and SMM-113-02-H-D?

A: The primary difference is contact finish. SMM-113-02-F-D features tin-plated posts with 3.00µin (0.076µm) gold mating contact finish. SMM-113-02-H-D features gold-plated posts (3.00µin / 0.076µm) with 30.0µin (0.76µm) gold mating contact finish, providing enhanced corrosion resistance on both contact surfaces.

Q: Does packaging format affect electrical performance?

A: No. Tube and Tape & Reel (TR) packaging variants contain identical connectors. Packaging selection is determined by assembly process requirements and inventory management practices.

Q: Are the Samtec substitutes RoHS compliant?

A: Samtec Tiger Eye™ SMM-113-02 variants are ROHS3 compliant where specified in product documentation. The original 3M 953226-2000-AR-TP does not carry RoHS certification due to its obsolete status.

Q: What is the significance of the "K" suffix in SMM-113-02-F-D-K?

A: The "K" suffix indicates pick-and-place feature compatibility, facilitating automated component placement during surface mount assembly. This does not affect electrical or mechanical interface specifications.

Q: Can I use SMM-113-02-F-D-LC as a direct replacement?

A: Yes. The "-LC" suffix indicates board lock feature, which provides additional mechanical retention without affecting the electrical interface or mating footprint. This is a functional enhancement suitable for applications requiring enhanced vibration resistance.
