SR07P24 Equivalent & Substitute Parts

Part Overview

The SR07P24 is a safety relay manufactured by Omron Automation and Safety, designed for DIN Rail mounting applications. This 3PST-NO (3 Form A) relay operates at 24VAC/DC with a 4A contact rating and supports switching voltages up to 250VAC and 30VDC. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for system maintenance and new installations where continued supply cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

The G9SA-301 AC/DC24 qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Coil Voltage: 24VAC/DC (identical)
• Contact Form: 3PST-NO (3 Form A) (identical)
• Switching Voltage: 250VAC, 30VDC - Max (identical)
• Mounting Type: DIN Rail (identical)
• Termination Style: Screw Terminal (identical)
• Manufacturer: Omron Automation and Safety (same manufacturer)

Differing Parameters:

• Contact Rating: G9SA-301 AC/DC24 provides 5A versus SR07P24's 4A (higher capacity, backward compatible)
• Operating Temperature: G9SA-301 AC/DC24 operates -25°C ~ 55°C versus SR07P24's -10°C ~ 55°C (wider range, backward compatible)
• Product Status: G9SA-301 AC/DC24 is Active (current production)

The G9SA-301 AC/DC24 maintains all critical electrical and mechanical compatibility parameters while offering enhanced specifications and current availability.

Engineering Selection Recommendations

The G9SA-301 AC/DC24 is the direct functional equivalent for SR07P24 applications. Selection is based on:

Product Status: The SR07P24 is obsolete, while G9SA-301 AC/DC24 maintains active production status, ensuring long-term availability and supply chain continuity.

Electrical Compatibility: Both relays share identical coil voltage (24VAC/DC), contact configuration (3PST-NO), and maximum switching voltage ratings (250VAC, 30VDC). The G9SA-301 AC/DC24's higher contact rating (5A versus 4A) provides additional capacity margin without compromising compatibility.

Mechanical Compatibility: Both relays use DIN Rail mounting and screw terminal connections, enabling direct installation in existing enclosures without mechanical modification.

Compliance: The G9SA-301 AC/DC24 is ROHS3 compliant and REACH affected, meeting current regulatory requirements. The SR07P24 carries no RoHS classification due to its obsolete status.

Frequently Asked Questions (FAQ)

Q: Can G9SA-301 AC/DC24 directly replace SR07P24 in existing installations?

A: Yes. Both relays share identical coil voltage, contact configuration, switching voltage ratings, mounting type, and termination style. Direct substitution is electrically and mechanically compatible.

Q: What is the significance of the higher 5A contact rating on G9SA-301 AC/DC24 compared to SR07P24's 4A?

A: The G9SA-301 AC/DC24's 5A rating exceeds the SR07P24's 4A specification, providing additional current-carrying capacity. This represents backward compatibility—applications designed for 4A operation function within the G9SA-301 AC/DC24's specifications.

Q: Does the wider operating temperature range of G9SA-301 AC/DC24 (-25°C ~ 55°C) affect compatibility?

A: No. The G9SA-301 AC/DC24's extended lower temperature limit (-25°C versus -10°C) is a superset of the SR07P24's range. Applications operating within SR07P24's original temperature envelope remain fully compatible.

Q: Are there packaging differences between these relays?

A: SR07P24 packaging is listed as standard, while G9SA-301 AC/DC24 is supplied in bulk packaging. Both use identical DIN Rail mounting and screw terminal connections.

Q: What compliance certifications apply to the substitute part?

A: G9SA-301 AC/DC24 is ROHS3 compliant and REACH affected, meeting current environmental and regulatory standards for electronic components.

Q: Why is SR07P24 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. G9SA-301 AC/DC24 maintains active production status, ensuring continued availability for new designs and system maintenance.
