73941-1021 Equivalent & Substitute Parts Reference

Part Overview

The Amphenol ICC (FCI) 73941-1021 is a backplane connector from the Metral® B Series. It is a 90-position receptacle with female sockets, designed for board edge, through hole, right angle mounting. The part status is documented as obsolete. Due to its obsolescence and non-compliance with RoHS requirements, it is necessary to consider equivalent and substitute models for new or ongoing designs. Identification of suitable substitutes requires strict adherence to specified electrical, mechanical, and compliance parameters relevant to backplane connector applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute groupings for the Amphenol ICC (FCI) 73941-1021 are determined by matching key parameters, including series/family, connector type (receptacle, female sockets), number of positions (90), number of rows (5), mounting type (board edge, through hole, right angle), termination method, contact finish specification, material flammability rating, and compliance certifications (RoHS, MSL). Only parts with explicit matching or specified relationships on these parameters are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between the Amphenol ICC (FCI) 73941-1021 and the direct substitute 73941-1021LF is governed by product status and compliance criteria. The 73941-1021 is obsolete and not RoHS compliant. In contrast, the 73941-1021LF is active and RoHS compliant, with equivalent key mechanical and electrical parameters and identical base part number within the specified category. For designs requiring active product status and RoHS compliance, 73941-1021LF meets these requirements.

Frequently Asked Questions (FAQ)

Q: What parameters must match for a valid substitute in backplane connectors?
A: Connector type, series, number of positions, number of rows, mounting type, termination method, contact finish/plating, MSL rating, material flammability rating, and compliance certifications must match as per provided specifications.

Q: Are 73941-1021 and 73941-1021LF mechanically interchangeable?
A: Both share the same base product number, connector type, number of positions, row count, mounting type, contact finish, and flammability rating, supporting mechanical substitution based on the supplied parameters.

Q: Are there differences in compliance status between the main part and the substitute?
A: The 73941-1021 is RoHS non-compliant and obsolete. The substitute 73941-1021LF is RoHS compliant and active.

Q: Is packaging information relevant for selection?
A: Packaging is not a fundamental fit, form, or function parameter for board-level integration, based solely on the provided information.

Q: Does the substitute part offer identical board-level features?
A: All features that are explicitly specified, including number of positions, mounting, contact finish, and material flammability, are matched between 73941-1021 and 73941-1021LF based on the input data.
