FH41-50S-0.5SH(99) Equivalent & Substitute Parts

Part Overview

The FH41-50S-0.5SH(99) is a 50-position FFC (Flat Flexible Connector) manufactured by Hirose Electric Co., Ltd., designed for surface mount, right-angle applications with 0.5mm pitch contacts. This connector features bottom-contact configuration, solder termination, and is rated for 0.5A at 50V with operating temperature range of -40°C to 105°C.

The FH41-50S-0.5SH(99) is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector.

Substitute Part Grouping Explanation

Substitution eligibility for the FH41-50S-0.5SH(99) is determined by strict equivalence across the following critical parameters:

50-position contact count
0.5mm pitch spacing
Surface mount, right-angle orientation
Bottom-contact configuration
Solder termination
0.30mm FFC thickness
2.50mm height above board
Flip Lock and Backlock locking features
Phosphor Bronze contacts with gold finish
Halogen-free LCP housing and actuator materials
50V voltage rating and 0.5A current rating
-40°C to 105°C operating temperature range
UL94 V-0 flammability rating
RoHS compliance

The FH41-50S-0.5SH(98) meets all these criteria and is therefore a direct substitute. Packaging format (Tape & Reel for the substitute versus unspecified for the main part) does not affect electrical or mechanical compatibility.
