Substitute Part Grouping Explanation

The substitute part identified for the FGRMS51-24-LED is the P7SA-14F-ND DC24, manufactured by Omron Automation and Safety. However, this substitute represents a functional category change rather than a direct relay replacement.

The P7SA-14F-ND DC24 is a relay socket designed for DIN Rail mounting with 14-position screw terminal connections, intended for use with the G7SA Series relays. This component serves as a mounting and connection interface rather than a direct functional equivalent to the FGRMS51-24-LED relay itself.

Substitution logic is based on the following parameters:

• Mounting Type: DIN Rail (common to both)
• Termination Style: Screw Terminal (common to both)
• Manufacturer: Omron Automation and Safety (common source)
• Product Status: Active availability (P7SA-14F-ND DC24 is active; FGRMS51-24-LED is obsolete)

Parameter Comparison

Engineering Selection Recommendations

The FGRMS51-24-LED is an obsolete product. For applications currently utilizing this relay, component selection must account for the following factors:

1. The P7SA-14F-ND DC24 is an active product with current manufacturing support and availability (275,891 pieces in stock versus 755 pieces for the obsolete FGRMS51-24-LED).

2. The P7SA-14F-ND DC24 is ROHS3 Compliant and REACH Affected, providing compliance with current environmental and regulatory standards. The FGRMS51-24-LED has undefined REACH status due to its obsolete classification.

3. Both components share identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating equivalent environmental tolerance.

4. Direct functional replacement of the FGRMS51-24-LED requires identification of an active relay model with matching electrical specifications (24VDC coil, 6PST contact configuration, 6A contact rating). The P7SA-14F-ND DC24 socket is a complementary component for relay mounting infrastructure rather than a direct relay substitute.

Frequently Asked Questions (FAQ)

Q: Is the P7SA-14F-ND DC24 a direct replacement for the FGRMS51-24-LED?

A: No. The P7SA-14F-ND DC24 is a relay socket designed for DIN Rail mounting, not a relay itself. It provides the mechanical and electrical interface for relay connection. A direct relay replacement requires an active model with matching 24VDC coil voltage, 6PST contact configuration, and 6A contact rating.

Q: Why is the FGRMS51-24-LED listed as obsolete?

A: The FGRMS51-24-LED has been discontinued by the manufacturer. Omron Automation and Safety no longer produces this model. Existing inventory (755 pieces) represents remaining stock only.

Q: What are the key parameters that determine relay substitution compatibility?

A: Coil voltage (24VDC), contact form (6PST-5NO/1NC), contact current rating (6A), switching voltage (250VAC, 125VDC maximum), and mounting type (DIN Rail) are the primary parameters governing relay substitution.

Q: Does the P7SA-14F-ND DC24 share environmental compliance with the FGRMS51-24-LED?

A: Both components have MSL 1 (Unlimited) ratings. The P7SA-14F-ND DC24 is ROHS3 Compliant and REACH Affected, providing current regulatory compliance. The FGRMS51-24-LED has undefined REACH status due to obsolescence.

Q: What is the screw terminal configuration difference between these components?

A: The FGRMS51-24-LED is a relay with integrated screw terminals for coil and contact connections. The P7SA-14F-ND DC24 is a 14-position socket with screw terminals designed to accept plug-in relay modules. These serve different functional roles in system architecture.
