Engineering Selection Recommendations

The MGN2A-AC240 is the qualified substitute for the obsolete PRD-7AG0-240. Selection is based on the following factors:

Product Status: The PRD-7AG0-240 is obsolete, while the MGN2A-AC240 is active and maintains current manufacturing support and availability.

Electrical Compatibility: Both relays operate at 240VAC coil voltage with identical DPST-NO contact configuration and 30A current rating. The MGN2A-AC240 demonstrates superior switching voltage capability (600VAC maximum versus 240VAC nominal), providing enhanced margin for application flexibility.

Mechanical Compatibility: Chassis mount configuration with screw terminal termination is identical between both parts, ensuring direct mechanical fit in existing installations.

Regulatory Compliance: Both parts meet EAR99 export classification and maintain identical HTSUS commodity codes. The MGN2A-AC240 holds RoHS compliance certification, meeting current environmental standards.

Operational Parameters: The MGN2A-AC240 exhibits faster operate time (30 ms versus 40 ms) and operates across a wider temperature range (-45°C to 80°C versus -55°C to 45°C), providing enhanced performance characteristics for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the MGN2A-AC240 directly replace the PRD-7AG0-240 in existing applications?

A: Yes. Both relays share identical coil voltage (240VAC), contact configuration (DPST-NO), current rating (30A), mounting type (chassis mount), and termination style (screw terminal). The MGN2A-AC240 is a direct functional equivalent.

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

A: The MGN2A-AC240 offers superior switching voltage capability (600VAC maximum versus 240VAC nominal), faster operate time (30 ms versus 40 ms), and a wider operating temperature range (-45°C to 80°C versus -55°C to 45°C). Coil current is slightly lower (40 mA versus 43 mA) and coil insulation class is higher (Class F versus Class B).

Q: Are there any compatibility concerns with coil current differences?

A: No. The coil current difference of 3 mA (40 mA versus 43 mA) is within normal tolerance for relay operation and does not affect circuit compatibility. Both relays operate at the same 240VAC coil voltage with nearly identical coil resistance (1.17 kOhms versus 1.2 kOhms).

Q: Does the MGN2A-AC240 meet the same regulatory requirements?

A: Yes. Both relays carry identical ECCN (EAR99) and HTSUS (8536.49.0075) classifications. The MGN2A-AC240 maintains RoHS compliance, meeting current environmental standards.

Q: What is the impact of faster operate time on system performance?

A: The MGN2A-AC240 operates 10 ms faster (30 ms versus 40 ms). This faster response time improves switching performance and may enhance system responsiveness in time-sensitive applications. This represents an improvement over the original part.

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

A: Both relays are supplied in bulk packaging as new original stock. The MGN2A-AC240 currently maintains higher inventory availability (911 pieces versus 741 pieces for the obsolete PRD-7AG0-240).
