SH2B-51 Equivalent & Substitute Parts

Part Overview

The SH2B-51 is an 8-position relay socket designed for panel mount applications with solder lug termination. Manufactured by IDEC as part of the SH series, this component is actively produced and maintains a stock of 762 units. The socket is engineered for use with RH series relays and provides a standardized interface for relay installation in control panel assemblies. Equivalent parts may be required due to supply chain considerations, regional availability, or system integration requirements where alternative relay socket architectures are specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SH2B-51 is determined by the following critical parameters:

• Number of Positions: Must be 8 positions to maintain electrical interface compatibility
• Mounting Type: Must be panel mount to ensure mechanical fit within existing panel cutouts
• Termination Style: Must be solder lug to maintain PCB assembly compatibility
• Type: Must be socket to provide the same functional interface for relay insertion

The PT08 manufactured by Omron Automation and Safety meets all four substitution criteria. Both components are active products with current manufacturing status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

Both the SH2B-51 and PT08 are active products with current manufacturing status, ensuring component availability for new designs and field replacements. The PT08 carries additional compliance certifications including RoHS3 compliance, REACH unaffected status, and defined ECCN/HTSUS classifications, which may be required for specific regulatory or export applications. Selection between these components should be based on relay series compatibility requirements and applicable compliance mandates for the end application.

Frequently Asked Questions (FAQ)

Q: Can the PT08 directly replace the SH2B-51 in existing assemblies?

A: The PT08 meets all critical substitution parameters: 8 positions, panel mount configuration, and solder lug termination. However, relay series compatibility must be verified. The SH2B-51 is specified for RH series relays, while the PT08 is specified for LY series relays. Physical fit and electrical interface compatibility with the relay type used in your application must be confirmed before substitution.

Q: What are the key parameters that determine socket substitution eligibility?

A: Four parameters are critical for relay socket substitution: number of positions (must be 8), mounting type (must be panel mount), termination style (must be solder lug), and component type (must be socket). Deviation from any of these parameters results in incompatibility.

Q: Are there compliance differences between these two sockets?

A: The PT08 includes documented RoHS3 compliance, REACH unaffected status, and ECCN/HTSUS classifications. The SH2B-51 specifications provided do not include these compliance certifications. If regulatory compliance documentation is required for your application, the PT08 provides explicit certification records.

Q: What is the inventory status for these components?

A: The SH2B-51 maintains 762 units in stock. The PT08 maintains 1122 units in stock. Both components are available in bulk packaging.
