FH33-40S-0.5SH Equivalent & Substitute Parts

Part Overview

The FH33-40S-0.5SH is a 40-position FFC/FPC connector manufactured by Hirose Electric Co Ltd, designed for flat flexible cable applications with 0.5mm pitch spacing. This connector is classified as obsolete, making identification of suitable substitute components essential for ongoing production support, maintenance, and design continuity. Equivalent parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FH33-40S-0.5SH are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Number of Positions: 40 positions (fixed requirement)
• Pitch Specification: 0.020" (0.50mm) center-to-center spacing (fixed requirement)
• Connector/Contact Type: Contacts, Bottom configuration (fixed requirement)
• Mounting Type: Surface Mount, Right Angle orientation (fixed requirement)
• Manufacturer Series: FH33 series (Hirose Electric Co Ltd)

All substitute parts listed maintain these core electrical and mechanical parameters, ensuring direct compatibility with existing PCB layouts and cable assemblies designed for the original FH33-40S-0.5SH connector.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are manufactured by Hirose Electric Co Ltd within the FH33 series and maintain identical electrical and mechanical specifications required for direct replacement of the obsolete FH33-40S-0.5SH connector.

Primary Substitute: FH33-40S-0.5SH(10) is the recommended substitute, offering active product status with Tape & Reel packaging, RoHS compliance, and MSL 1 rating. This variant is currently in production and widely available.

Alternative Substitutes: FH33-40S-0.5SH(99), FH33J-40S-0.5SH(99), and FH33J-40S-0.5SH(10) provide equivalent electrical and mechanical compatibility. The FH33J variants represent alternative housing configurations within the same series, maintaining all critical connector parameters.

All substitute options are RoHS compliant and rated for -55°C to 85°C operating temperature, meeting modern environmental and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can FH33-40S-0.5SH(10) be used as a direct replacement for FH33-40S-0.5SH?

A: Yes. Both connectors maintain identical position count (40), pitch spacing (0.5mm), contact configuration (bottom), and mounting type (surface mount, right angle). The primary difference is product status: the original is obsolete while the substitute is active production.

Q: What is the difference between FH33-40S-0.5SH(10) and FH33-40S-0.5SH(99)?

A: The numeric suffix indicates packaging configuration. Both maintain identical electrical and mechanical specifications. Selection depends on procurement and assembly requirements.

Q: Are FH33J variants compatible with FH33 connectors?

A: FH33J variants maintain the same position count, pitch, contact type, and mounting configuration as FH33 connectors. Compatibility is determined by these core parameters, which remain constant across both series designations.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitute parts meet RoHS compliance requirements, supporting modern manufacturing and environmental standards.
