Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRD-3AG0-24 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Contact form configuration: SPST-NO (1 Form X)
• Coil voltage: 24VAC
• Contact current rating: 30 A minimum
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Coil type: Non Latching

Operational Compatibility Parameters:

• Must operate voltage: 20.4 VAC or lower
• Coil resistance within acceptable tolerance range
• Operating temperature range that encompasses or exceeds -55°C to 45°C
• Compliance certifications: RoHS and ECCN EAR99

The MGN1X-AC24 from Omron Automation and Safety meets all critical matching parameters and operational compatibility requirements, qualifying it as a direct substitute for the obsolete PRD-3AG0-24.

Parameter Comparison

Engineering Selection Recommendations

The MGN1X-AC24 is the qualified substitute for the obsolete PRD-3AG0-24 based on the following engineering criteria:

Functional Equivalence: Both relays share identical contact form configuration (SPST-NO), coil voltage (24VAC), current rating (30A), mounting type (Chassis Mount), and termination style (Screw Terminal). Coil resistance values are within 4% tolerance (12 Ohms vs. 11.5 Ohms), ensuring compatible circuit behavior.

Compliance Status: The MGN1X-AC24 maintains active product status with current RoHS compliance certification and EAR99 ECCN classification, matching the regulatory framework of the original part. Both components carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Operational Performance: The MGN1X-AC24 demonstrates superior switching voltage capability (600VAC maximum vs. 277VAC nominal) and extended operating temperature range (-45°C to 80°C vs. -55°C to 45°C). Operate time is improved at 30 ms versus 40 ms. Coil current draw is slightly lower at 396 mA compared to 410 mA, reducing power consumption.

Thermal Characteristics: The substitute part features Class F coil insulation compared to Class B in the original, providing enhanced thermal stability for extended operational life.

Frequently Asked Questions (FAQ)

Q: Can the MGN1X-AC24 directly replace the PRD-3AG0-24 in existing applications?

A: Yes. Both relays meet identical specifications for contact form, coil voltage, current rating, mounting configuration, and termination style. The MGN1X-AC24 is electrically and mechanically compatible for direct substitution in chassis-mounted 24VAC SPST-NO relay applications rated for 30A.

Q: What are the key differences between these two relays?

A: The primary differences are: (1) Switching voltage capability—MGN1X-AC24 supports 600VAC maximum versus 277VAC nominal for PRD-3AG0-24; (2) Operating temperature range—MGN1X-AC24 extends to 80°C versus 45°C maximum; (3) Coil insulation class—MGN1X-AC24 uses Class F versus Class B; (4) Timing characteristics—MGN1X-AC24 operates faster at 30 ms versus 40 ms. These differences represent performance enhancements in the substitute part.

Q: Are there any compatibility concerns with screw terminal connections?

A: No. Both relays use identical screw terminal termination style, ensuring direct mechanical and electrical compatibility without connector modifications.

Q: Does the MGN1X-AC24 meet the same regulatory requirements?

A: Yes. The MGN1X-AC24 is RoHS compliant and carries EAR99 ECCN classification, matching the regulatory compliance profile of the PRD-3AG0-24. Both components have MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the coil current difference between these relays?

A: The MGN1X-AC24 draws 396 mA compared to 410 mA for the PRD-3AG0-24. This 14 mA reduction (3.4% lower) results in decreased power consumption and reduced heat generation in the coil circuit.

Q: Can the MGN1X-AC24 operate in the full temperature range of the original part?

A: The MGN1X-AC24 operates from -45°C to 80°C, which covers the original part's range of -55°C to 45°C except for the lower extreme of -55°C. For applications requiring operation below -45°C, the original PRD-3AG0-24 specification must be maintained.

Q: Is the MGN1X-AC24 currently available?

A: Yes. The MGN1X-AC24 is classified as an active product with current manufacturing status, ensuring ongoing availability and supply chain reliability compared to the obsolete PRD-3AG0-24.
