Key Parameters

Substitute Part Grouping Explanation

Substitution of the MT236115 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Contact Form: DPDT (2 Form C)
• Coil Voltage: 115VAC
• Contact Rating (Current): 10 A
• Switching Voltage (Max): 400VAC
• Termination Style: Plug In, 8 Pin (Octal)
• Mounting Type: Socketable
• Coil Type: Non Latching
• Operating Temperature Range: -40°C ~ 50°C
• Contact Material: Silver Nickel (AgNi)
• Coil Resistance: 2 kOhms

The Weidmüller part number 8690310000 satisfies all mandatory matching parameters, establishing it as a direct functional equivalent. Both relays operate identically within the specified electrical and mechanical constraints, with differences limited to operational voltage thresholds and coil current characteristics that remain within acceptable system tolerance ranges.

Engineering Selection Recommendations

The Weidmüller 8690310000 relay is the direct equivalent substitute for the obsolete MT236115. Selection of this substitute is supported by the following engineering criteria:

Product Status Alignment: The MT236115 is classified as obsolete, while the Weidmüller 8690310000 maintains active product status, ensuring continued availability and manufacturing support for procurement and replacement requirements.

Compliance Certification: Both relays maintain equivalent environmental and regulatory compliance. The MT236115 is ROHS3 compliant, and the Weidmüller 8690310000 is RoHS compliant. Both are classified under ECCN EAR99 and share identical HTSUS coding (8536.49.0075), confirming regulatory equivalence.

Electrical and Mechanical Compatibility: The substitute part maintains identical specifications across all critical functional parameters: DPDT contact form, 115VAC coil voltage, 10A contact rating, 400VAC maximum switching voltage, 8-pin octal socketable termination, and operating temperature range of -40°C to 50°C. Coil resistance remains at 2 kOhms with identical operate and release times of 15 ms and 10 ms respectively.

Operational Threshold Variation: The Weidmüller 8690310000 exhibits a lower must-release voltage of 34.5 VAC compared to the MT236115 at 46 VAC. This difference represents improved release sensitivity and does not compromise system functionality, as both relays maintain the identical must-operate voltage of 92 VAC. The lower release threshold provides operational margin within standard AC supply voltage variations.

Moisture and Environmental Protection: Both relays maintain MSL rating of 1 (Unlimited), confirming equivalent environmental protection and storage stability.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 8690310000 be used as a direct replacement for the MT236115 in existing systems?

A: Yes. The Weidmüller 8690310000 is a direct functional equivalent. Both relays share identical contact form (DPDT), coil voltage (115VAC), contact rating (10A), switching voltage (400VAC maximum), termination style (8-pin octal socketable), and operating temperature range (-40°C to 50°C). The relays are mechanically and electrically interchangeable within the same socket.

Q: What is the significance of the different must-release voltages between the two relays?

A: The MT236115 requires 46 VAC to release, while the Weidmüller 8690310000 releases at 34.5 VAC. Both maintain the same must-operate voltage of 92 VAC. The lower release threshold of the Weidmüller relay represents improved sensitivity and does not create compatibility issues. System performance remains equivalent across standard AC supply voltage ranges.

Q: Are there any packaging or inventory differences between these relays?

A: The MT236115 is packaged as individual units with 738 pieces in stock. The Weidmüller 8690310000 is supplied in bulk packaging with 694 pieces in stock. Both are socketable relays with 8-pin octal termination, requiring identical socket hardware for installation.

Q: Do both relays meet current environmental and regulatory requirements?

A: Yes. The MT236115 is ROHS3 compliant, and the Weidmüller 8690310000 is RoHS compliant. Both relays share identical ECCN classification (EAR99) and HTSUS code (8536.49.0075). Both maintain MSL rating of 1 (Unlimited), confirming equivalent environmental protection standards.

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

A: The Weidmüller 8690310000 specifies a coil current of 20.6 mA. The MT236115 coil current is not specified in the available documentation. Both relays maintain identical coil resistance of 2 kOhms and identical must-operate voltage of 92 VAC, ensuring equivalent power supply requirements and control circuit compatibility.

Q: Are the operate and release times identical between these relays?

A: Yes. Both the MT236115 and Weidmüller 8690310000 maintain identical operate time of 15 ms and release time of 10 ms, ensuring equivalent switching performance and timing characteristics in control applications.

Q: Can the Weidmüller relay be used in new designs as a replacement for the obsolete MT236115?

A: Yes. The Weidmüller 8690310000 is the recommended substitute for new designs requiring DPDT 10A 115VAC relay functionality. The active product status of the Weidmüller relay ensures long-term availability and manufacturing support, eliminating obsolescence risk associated with the MT236115.
