Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer):

The 5953398-2 from TE Connectivity AMP Connectors is the direct equivalent to the 5953398-1. Both parts share identical electrical and mechanical specifications, including 10-position configuration, 0.346" (8.80mm) height above board, and board lock/switch features. The 5953398-2 maintains the same RoHS compliance and MSL rating. However, both parts are classified as obsolete, limiting long-term procurement viability.

Active Substitute Options (Amphenol ICC / FCI):

Three active substitute connectors from Amphenol ICC (FCI) provide functional equivalence with improved product availability:

7334L2622F05LF and 7334L2625F05LF (L26 Series) are 10-position smart card connectors with identical position count and insertion/removal method. Both incorporate board guide features in addition to board lock and switch functionality. The 7334L2622F05LF features GXT™ contact finish technology and is available in higher inventory (1,896 pcs). The 7334L2625F05LF provides standard gold contact finish. Height above board for both is 0.411" (10.45mm), representing a 0.065" (1.65mm) increase from the original specification.

7434L0825S01LF (L08 Series) is a 10-position smart card connector with GXT™ contact finish and board guide features. Height above board is 0.354" (9.00mm), providing closer dimensional alignment to the original 5953398-1 specification. This part is subject to REACH regulations (REACH Affected status).

7334L2620F05LF (L26 Series) is an 8-position connector and does not meet the 10-position requirement of the original specification. This part is not recommended as a direct substitute.

All active Amphenol ICC (FCI) alternatives maintain RoHS compliance, MSL 1 rating, and push-in/pull-out insertion methodology. Selection between active substitutes depends on mechanical height constraints and REACH compliance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 5953398-1 be directly replaced with the 5953398-2?

A: Yes. The 5953398-2 is a direct equivalent with identical electrical and mechanical specifications. Both parts are obsolete, so long-term availability is limited for both options.

Q: What is the primary difference between the TE Connectivity 5953398-2 and the Amphenol ICC alternatives?

A: The 5953398-2 maintains the original 0.346" (8.80mm) height above board. Amphenol ICC alternatives (7334L2622F05LF, 7334L2625F05LF) increase this height to 0.411" (10.45mm), while the 7434L0825S01LF provides 0.354" (9.00mm). Height differences affect PCB layout and mechanical clearance requirements.

Q: Are the Amphenol ICC (FCI) substitutes electrically compatible with the 5953398-1?

A: Yes. All recommended Amphenol ICC (FCI) substitutes maintain the same 10-position smart card configuration, push-in/pull-out insertion method, gold contact finish, and board lock/switch features. Electrical interface compatibility is maintained across all active substitutes.

Q: Why is the 7334L2620F05LF not recommended as a substitute?

A: The 7334L2620F05LF is an 8-position connector, not a 10-position connector. The original 5953398-1 requires 10 positions (8 + 2). Position count is a critical substitution parameter and cannot be compromised.

Q: What does GXT™ contact finish mean, and does it affect substitution compatibility?

A: GXT™ is an enhanced gold contact finish technology offered by Amphenol ICC (FCI). Parts with GXT™ finish (7334L2622F05LF, 7434L0825S01LF) provide improved contact durability and performance compared to standard gold finish. GXT™ finish does not prevent substitution; it represents an enhancement that maintains backward compatibility.

Q: Are there REACH compliance considerations for substitute selection?

A: The 7434L0825S01LF is marked as REACH Affected, indicating it contains substances of concern under REACH regulations. The 7334L2622F05LF and 7334L2625F05LF are marked as REACH Unaffected. Applications subject to REACH compliance requirements should prioritize REACH Unaffected alternatives.

Q: What is the inventory status of available substitutes?

A: The 7334L2622F05LF offers the highest inventory availability (1,896 pcs), followed by 7434L0825S01LF (1,134 pcs), 5953398-2 (1,063 pcs), 7334L2620F05LF (847 pcs), and 7334L2625F05LF (785 pcs). Inventory levels support procurement planning for volume requirements.

Q: Can the board guide feature on Amphenol ICC alternatives replace the board lock feature of the original?

A: No. Board guide and board lock are distinct features. All recommended Amphenol ICC alternatives include both board guide and board lock functionality, providing equivalent or enhanced mechanical retention compared to the original 5953398-1, which includes board lock and switch features.
