SH4B-51 Equivalent & Substitute Parts

Part Overview

The SH4B-51 is a 14-position relay socket designed for panel mount applications with solder lug termination. Manufactured by IDEC as part of the RH Series, this component is classified as Active product status. Finding equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain compatibility across different relay socket applications where the RH Series socket may not be available or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SH4B-51 are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Number of Positions: 14 positions (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Termination Style: Solder Lug (exact match required)
• Type: Socket (exact match required)

The PT14 from Omron Automation and Safety meets all four critical substitution criteria. While the PT14 belongs to the LY Series (different from the RH Series of the main part), it maintains identical electrical and mechanical specifications for the core socket function. Both components are classified as Active products, ensuring current availability and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

Both the SH4B-51 and PT14 are Active products with current manufacturer support. The PT14 carries additional compliance certifications: RoHS3 Compliant, REACH Unaffected status, and assigned ECCN (EAR99) and HTSUS (8536.69.4030) codes. The PT14 specifies Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Selection between these parts should be based on supply availability, cost considerations, and any system-level requirements for specific compliance certifications. Both components satisfy the core electrical and mechanical requirements for 14-position panel mount relay socket applications with solder lug termination.

Frequently Asked Questions (FAQ)

Q: Can the PT14 directly replace the SH4B-51 in existing designs?

A: Yes. Both components share identical specifications for the four critical substitution parameters: 14 positions, panel mount configuration, solder lug termination, and socket type. Physical and electrical compatibility is maintained.

Q: What is the difference between the RH Series and LY Series sockets?

A: The series designation indicates the relay family each socket is designed to interface with. The RH Series socket (SH4B-51) is optimized for RH Series relays, while the LY Series socket (PT14) is optimized for LY Series relays and 4PDT relay configurations. Both sockets maintain identical 14-position panel mount specifications.

Q: Are there compliance or certification differences between these parts?

A: The PT14 includes documented RoHS3 Compliance, REACH Unaffected status, and regulatory codes (ECCN: EAR99; HTSUS: 8536.69.4030). The SH4B-51 specifications provided do not include these certifications. If compliance documentation is required for your application, the PT14 offers explicit certification records.

Q: What does MSL 1 (Unlimited) mean for the PT14?

A: Moisture Sensitivity Level 1 indicates the component has no moisture sensitivity constraints. The PT14 can be stored and handled without special moisture control measures, simplifying inventory and assembly processes.

Q: Are both parts available in the same packaging format?

A: Yes. Both the SH4B-51 and PT14 are supplied in Bulk packaging, maintaining consistency in procurement and handling procedures.
