SH3B-05 Relay Socket Equivalent & Substitute Parts

Part Overview

The SH3B-05 is an 11-position DIN rail-mounted relay socket manufactured by IDEC. This component serves as an interface for relay modules within the RH Series, utilizing screw terminal connections for secure wiring. The part maintains Active product status with 809 units currently in stock. Alternative components may be required due to supply constraints, design standardization across manufacturing facilities, or system integration requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SH3B-05 is determined by the following critical parameters:

• Number of Positions: Must equal 11 positions
• Mounting Type: Must be DIN Rail
• Termination Style: Must be Screw Terminal
• Type: Must be Socket configuration
• Regulatory Compliance: Must maintain ROHS3 Compliant and REACH Unaffected status

The PTF11A manufactured by Omron Automation and Safety satisfies all substitution criteria. Both components share identical functional specifications for position count, mounting method, and termination approach. Both maintain equivalent regulatory compliance certifications required for industrial applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SH3B-05 and PTF11A maintain Active product status, ensuring continued manufacturer support and availability. Both components hold ROHS3 Compliant certification and REACH Unaffected status, meeting regulatory requirements for industrial control applications.

Selection between these components should be based on:

• Supply availability: PTF11A currently maintains higher inventory (5918 units) compared to SH3B-05 (809 units)
• Packaging requirements: SH3B-05 is supplied in Bulk packaging; PTF11A is supplied in Tray packaging
• Series compatibility: Verify relay module series compatibility—SH3B-05 interfaces with RH Series relays; PTF11A interfaces with LY Series relays and 3PDT configurations

Frequently Asked Questions (FAQ)

Q: Can PTF11A directly replace SH3B-05 in existing installations?

A: Functional substitution is possible when the relay module series is compatible. The PTF11A is designed for LY Series relays, while the SH3B-05 is designed for RH Series relays. Verify that your relay modules are compatible with the Omron LY Series before substitution.

Q: What are the critical parameters that determine substitution compatibility?

A: The following parameters must match: 11-position configuration, DIN rail mounting, screw terminal termination, and socket type. Both components meet these requirements.

Q: Are there compliance differences between these components?

A: Both components maintain identical regulatory compliance: ROHS3 Compliant and REACH Unaffected status. No compliance barriers exist for substitution.

Q: Does packaging type affect electrical performance?

A: Packaging type (Bulk versus Tray) does not affect electrical performance or functional compatibility. Selection should be based on procurement and inventory management requirements.

Q: What should be verified before implementing a substitution?

A: Confirm that your relay module series is compatible with the substitute component's intended series. The SH3B-05 works with RH Series relays; the PTF11A works with LY Series relays. Physical dimensions and mounting clearances should be verified against your installation specifications.
