PRD-3DG0-24 Equivalent & Substitute Parts

Part Overview

The PRD-3DG0-24 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays. This SPST-NO (Single Pole Single Throw - Normally Open) relay is rated for 30A at 24VDC coil voltage with chassis mount configuration and screw terminal termination. The part is classified as obsolete, necessitating identification of active equivalent components for continued system support and new designs. Substitute parts must maintain functional compatibility across coil voltage, contact rating, contact form, and termination style parameters.

Substitute Part Grouping Explanation

Substitution of the PRD-3DG0-24 is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

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

The MGN1X-DC24 from Omron Automation and Safety satisfies all mandatory matching parameters. Both relays operate at identical coil voltage, maintain the same contact configuration, support equivalent current ratings, and utilize identical mounting and termination methods. The substitute part is classified as active product status, ensuring ongoing availability and support.

Engineering Selection Recommendations

The MGN1X-DC24 is a direct functional equivalent to the obsolete PRD-3DG0-24. Both components share identical electrical specifications for coil voltage, contact configuration, and current rating. The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain continuity.

The MGN1X-DC24 demonstrates superior compliance posture with RoHS certification and an extended operating temperature range (-40°C ~ 115°C versus -55°C ~ 80°C). Both parts maintain equivalent moisture sensitivity ratings and export classification codes. The Omron relay features Class F coil insulation compared to Class B in the original part, providing enhanced thermal performance.

Timing characteristics differ slightly between the two relays. The MGN1X-DC24 exhibits faster operate time (30 ms versus 40 ms) and equivalent release time (30 ms versus 20 ms). These timing variations remain within typical general purpose relay tolerances and do not preclude direct substitution in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the MGN1X-DC24 directly replace the PRD-3DG0-24 in existing designs?

A: Yes. Both relays maintain identical coil voltage (24VDC), contact form (SPST-NO), current rating (30A), mounting configuration (Chassis Mount), and termination style (Screw Terminal). Electrical and mechanical compatibility is established across all critical parameters.

Q: What are the differences in operating temperature ranges?

A: The PRD-3DG0-24 operates from -55°C to 80°C, while the MGN1X-DC24 operates from -40°C to 115°C. The substitute part provides a wider upper temperature limit. Applications requiring operation below -40°C require evaluation of the original specification.

Q: How do the timing characteristics compare?

A: The MGN1X-DC24 operates faster (30 ms operate time versus 40 ms) and releases at the same speed (30 ms versus 20 ms). These differences are within standard relay tolerances and do not affect compatibility in general purpose switching applications.

Q: Are both parts RoHS compliant?

A: Yes. The PRD-3DG0-24 is ROHS3 Compliant, and the MGN1X-DC24 is RoHS Compliant. Both parts meet regulatory requirements for hazardous substance restrictions.

Q: What is the difference in coil insulation class?

A: The PRD-3DG0-24 uses Class B insulation, while the MGN1X-DC24 uses Class F insulation. Class F provides higher thermal capability and represents an improvement in thermal performance.

Q: Are the coil current and resistance specifications equivalent?

A: The specifications are nearly identical. Coil current is 84 mA (PRD-3DG0-24) versus 83.3 mA (MGN1X-DC24), and coil resistance is 288 Ohms versus 290 Ohms. These minor variations are within acceptable engineering tolerances for relay substitution.

Q: What is the packaging configuration for the substitute part?

A: The MGN1X-DC24 is supplied in Bulk packaging, compared to the original part's standard packaging. Confirm packaging requirements for procurement and inventory management.
