MT336115 General Purpose Relay 3PDT 10A 115VAC Equivalent & Substitute Parts

Part Overview

The MT336115 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, featuring a 3PDT (3 Form C) contact configuration with a 115VAC coil. This socketable relay is designed for applications requiring 10A switching capacity at up to 400VAC. The MT336115 is classified as obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and redesign applications. Substitute parts must maintain functional equivalence across coil voltage, contact configuration, current rating, and termination style to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MT336115 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Coil voltage: 115VAC (exact match required)
• Contact form: 3PDT (3 Form C) configuration (exact match required)
• Contact rating: 10A minimum (exact match required)
• Switching voltage: 400VAC maximum (exact match or higher required)
• Termination style: Plug In, 11 Pin (Octal) (exact match required)
• Mounting type: Socketable (exact match required)
• Coil type: Non Latching (exact match required)
• Contact material: Silver Nickel (AgNi) (exact match required)

The Weidmüller part number 8690550000 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both relays operate at identical coil voltage, contact configuration, current rating, and termination specifications. The substitute part maintains functional equivalence for socketable installation and switching performance.

Engineering Selection Recommendations

The Weidmüller 8690550000 relay is a direct functional equivalent to the obsolete MT336115. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The MT336115 is classified as obsolete, while the Weidmüller 8690550000 maintains active product status with current manufacturing and availability.

Compliance Alignment: Both parts maintain RoHS compliance. The MT336115 carries ROHS3 Compliant status, while the Weidmüller part is RoHS Compliant. Both parts are classified under ECCN EAR99 and share the same HTSUS code (8536.49.0075), confirming regulatory equivalence.

Electrical Performance: All critical electrical parameters match identically, including coil voltage, contact configuration, current rating, switching voltage, and timing specifications. The substitute part exhibits a lower must-release voltage (34.5 VAC versus 46 VAC), which represents an operational advantage in applications requiring faster release response.

Thermal Performance: The Weidmüller substitute extends the operating temperature range to -40°C ~ 60°C, compared to the original -40°C ~ 50°C specification, providing enhanced performance in elevated temperature environments.

Mechanical Compatibility: Both relays feature identical socketable mounting with 11-pin octal termination, ensuring direct physical and electrical compatibility in existing socket installations.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 8690550000 directly replace the MT336115 in existing applications?

A: Yes. The Weidmüller 8690550000 is a direct substitute. Both relays share identical coil voltage (115VAC), contact configuration (3PDT), current rating (10A), switching voltage (400VAC maximum), and 11-pin octal socketable termination. Physical and electrical compatibility is confirmed for direct socket replacement.

Q: What is the significance of the lower must-release voltage in the substitute part?

A: The Weidmüller 8690550000 specifies a must-release voltage of 34.5 VAC compared to 46 VAC for the MT336115. This lower threshold indicates the substitute part releases its contacts at a lower coil voltage, which can result in faster release response in applications where coil voltage is reduced. This represents an operational improvement and does not compromise compatibility.

Q: Are there any temperature-related differences between these relays?

A: The Weidmüller substitute extends the maximum operating temperature from 50°C to 60°C. The minimum operating temperature remains -40°C for both parts. This extended upper temperature range provides additional operational margin in applications subject to elevated ambient or internal heat conditions.

Q: Do both relays meet current regulatory compliance requirements?

A: Yes. Both the MT336115 and Weidmüller 8690550000 are RoHS compliant. The MT336115 carries ROHS3 Compliant designation, while the Weidmüller part is RoHS Compliant. Both parts share identical ECCN (EAR99) and HTSUS (8536.49.0075) classifications, confirming regulatory equivalence for procurement and deployment.

Q: What is the coil resistance specification for both relays?

A: Both relays specify 2 kOhms coil resistance, confirming identical electrical load characteristics for control circuits and power supply design.

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

A: Yes. Both relays specify 15 milliseconds operate time and 10 milliseconds release time, ensuring identical switching response characteristics in timing-sensitive applications.

Q: What contact material is used in both relays?

A: Both relays employ Silver Nickel (AgNi) contact material, providing identical electrical conductivity, arc resistance, and contact wear characteristics.

Q: Is the test button feature present on both relays?

A: Yes. Both the MT336115 and Weidmüller 8690550000 include a test button feature for manual relay actuation and functional verification.
