Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 535653-1 with the 5535653-1 is based on strict equivalence across all critical electrical and mechanical parameters. Both connectors share identical specifications for card type (PCMCIA), position count (68), insertion/removal method (push-in/pull-out), mounting configuration (through-hole, right-angle), board height (0.275"), contact finish (gold), contact finish thickness (30.0µin), and moisture sensitivity rating (MSL 1). The substitute part maintains full mechanical and electrical compatibility while differing in product status (active versus obsolete) and regulatory compliance posture. The substitution is valid for applications requiring direct form, fit, and function replacement.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5535653-1 serves as the direct functional equivalent to the obsolete 535653-1 PCMCIA connector. Selection of the substitute part is supported by the following engineering criteria:

Product Status: The 5535653-1 maintains active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The 535653-1 is classified as obsolete, limiting future procurement options.

Regulatory Compliance: The 5535653-1 is ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations. The 535653-1 is RoHS non-compliant with undefined REACH status, presenting compliance risk in regulated applications.

Electrical and Mechanical Equivalence: All critical parameters—card type, position count, insertion method, mounting configuration, board height, contact finish, and moisture sensitivity—are identical between the two parts, ensuring direct substitution without design modification.

Inventory and Availability: The 5535653-1 is available in higher inventory quantities (2608 pieces) compared to the 535653-1 (663 pieces), supporting procurement reliability.
