Substitute Part Grouping Explanation

Substitute parts for the SFML-115-02-S-D-LC are qualified based on strict equivalence across the following critical parameters:

Connector Type & Position Configuration: All substitutes maintain 30-position receptacle design with 2-row configuration
Pitch & Spacing: Mating pitch of 0.050" (1.27mm) and row spacing of 0.050" (1.27mm) are identical across all parts
Electrical Ratings: Current rating of 3.2A per contact and 250VAC voltage rating remain constant
Contact System: Gold-plated mating contacts with 30.0µin (0.76µm) thickness specification
Mounting & Termination: Surface mount solder termination with locking ramp fastening
Environmental Compliance: UL94 V-0 flammability, ROHS3 compliance, and -55°C ~ 125°C operating temperature range
Insulation Material: Liquid Crystal Polymer (LCP) with black color and 0.185" (4.70mm) height

The substitute parts differ only in internal design variations (indicated by the T2 designation in part numbering) that do not affect electrical or mechanical interface compatibility.
