MT321024 General Purpose Relay 3PDT 10A 24VDC

Part Overview

The MT321024 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, featuring a 3PDT (3 Form C) contact configuration with a 24VDC coil. This socketable relay is rated for 10A switching capacity at up to 400VAC maximum switching voltage. The MT321024 is classified as obsolete, making identification of suitable substitute components necessary for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the MT321024 are identified based on electrical and mechanical compatibility within the general purpose relay category. The substitution criteria are strictly limited to the following parameters:

Coil voltage must be 24VDC. Contact form must be 3PDT (3 Form C). Contact rating must be 10A. Switching voltage maximum must be 400VAC or greater. Mounting type must be socketable. Termination style must be plug-in, 11-pin octal configuration. Coil current must be within the specified range. Must operate and release voltages must match the original specification. Operating temperature range must encompass -40°C to 60°C. Contact material must be Silver Nickel (AgNi). Coil resistance must be 475 Ohms.

Only components meeting all of these criteria are considered direct substitutes for the MT321024.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 8690610000 relay is a direct substitute for the obsolete MT321024. Both components share identical electrical specifications across all critical parameters including coil voltage, contact configuration, current rating, switching voltage, and operating characteristics. The coil current differential of 0.5 mA between the two relays is within acceptable tolerance for general purpose relay applications and does not affect functional compatibility.

The Weidmüller 8690610000 holds active product status, ensuring ongoing availability and supply chain continuity. Both components maintain equivalent RoHS and REACH compliance certifications, with identical ECCN and HTSUS classifications. The socketable, 11-pin octal termination style ensures mechanical and electrical interchangeability in existing relay socket installations.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 8690610000 be used as a direct replacement for the MT321024 in existing applications?

A: Yes. The Weidmüller 8690610000 meets all electrical and mechanical specifications of the MT321024. Both relays feature identical coil voltage, contact form, current rating, switching voltage, termination style, and operating characteristics. The socketable design and 11-pin octal configuration ensure direct compatibility in existing relay socket installations.

Q: What is the significance of the 0.5 mA difference in coil current between the two relays?

A: The coil current difference of 0.5 mA (MT321024 at 50 mA versus 8690610000 at 50.5 mA) is negligible for general purpose relay applications. Both values fall within standard tolerance ranges for relay coil specifications and do not affect circuit performance or compatibility.

Q: Are there any compliance or certification differences between the MT321024 and the Weidmüller 8690610000?

A: Both relays maintain equivalent environmental and regulatory compliance. The MT321024 is ROHS3 compliant while the Weidmüller 8690610000 is RoHS compliant. Both are REACH unaffected and share identical ECCN (EAR99) and HTSUS (8536.41.0050) classifications.

Q: Does the socketable mounting type ensure compatibility with existing relay bases?

A: Yes. Both the MT321024 and Weidmüller 8690610000 feature socketable mounting with 11-pin octal plug-in termination. This standardized configuration ensures mechanical and electrical compatibility with relay bases designed for octal socket mounting.

Q: What are the key parameters that determine substitution eligibility for this relay category?

A: Substitution eligibility is determined by matching coil voltage, contact form (3PDT), current rating (10A), switching voltage (400VAC maximum), mounting type (socketable), termination style (11-pin octal), coil current, must operate and release voltages, operating temperature range, contact material (Silver Nickel), and coil resistance (475 Ohms). All parameters must align for direct substitution.
