MT328230 General Purpose Relay 3PDT 10A 230VAC

Part Overview

The MT328230 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, featuring a 3PDT (3 Form C) contact configuration with a 230VAC coil. This socketable relay is designed for applications requiring 10A switching capacity at up to 400VAC. The MT328230 is classified as obsolete, necessitating identification of active substitute components that maintain electrical and mechanical compatibility for continued system operation and maintenance.

Engineering Selection Recommendations

The Weidmüller 8690580000 relay is a direct functional equivalent to the obsolete MT328230. Selection of this substitute is supported by the following factors:

Electrical Equivalence: All critical electrical parameters match exactly, including coil voltage, contact configuration, current rating, switching voltage, and timing characteristics. Coil resistance and operating voltage thresholds are identical.

Mechanical Compatibility: The socketable mounting type and 11-pin octal termination style enable direct installation into existing MT328230 sockets without modification.

Compliance Status: The Weidmüller 8690580000 is RoHS compliant and currently in active production, ensuring long-term availability and supply chain continuity. The MT328230 is obsolete and no longer manufactured.

Operating Temperature: The substitute component supports an extended operating temperature range (-40°C to 60°C) compared to the original part (-40°C to 50°C), providing enhanced thermal margin for demanding applications.

Functional Features: Both relays include lighted indicator and test button functionality, maintaining operational visibility and testing capability in the field.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 8690580000 be used as a direct replacement for the MT328230 in existing installations?

A: Yes. The 8690580000 is electrically and mechanically equivalent to the MT328230. It features identical coil voltage (230VAC), contact configuration (3PDT), current rating (10A), switching voltage (400VAC), and termination style (11-pin octal socketable). Direct installation into existing MT328230 sockets is supported without circuit modification.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by equivalence in coil voltage, contact form (3PDT), contact current rating (10A), switching voltage (400VAC maximum), mounting type (socketable), termination style (11-pin octal), coil type (non-latching), and contact material (Silver Nickel). All these parameters must match for functional equivalence.

Q: Why is the MT328230 being replaced?

A: The MT328230 is classified as obsolete and is no longer in active production. The Weidmüller 8690580000 provides equivalent functionality with the advantage of current manufacturing status and long-term availability.

Q: Are there any compliance differences between the two relays?

A: Both relays are RoHS compliant. The Weidmüller 8690580000 carries RoHS compliance certification and is REACH unaffected. Both components share the same ECCN (EAR99) and HTSUS classification.

Q: Does the operating temperature range difference affect substitution?

A: No. The Weidmüller 8690580000 supports an extended operating temperature range (-40°C to 60°C) compared to the MT328230 (-40°C to 50°C). This provides additional thermal margin and does not restrict substitution in applications designed for the original part's temperature range.

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

A: The Weidmüller 8690580000 is supplied in bulk packaging. Inventory availability is 823 pieces of new original stock.
