Honeywell 31NT92-2 Toggle Switch Equivalent & Substitute Parts

Part Overview

The Honeywell 31NT92-2 is an SPST (Single Pole Single Throw) panel mount toggle switch rated for 15A at 125V AC. This sealed, non-illuminated switch features a standard round actuator with solder lug termination and operates across a temperature range of -40°C to 71°C. The part is currently in active product status with 801 units available in inventory.

Identification of substitute parts becomes necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements permit operation with alternative specifications that maintain functional compatibility within the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Honeywell 31NT92-2 toggle switch is determined by alignment across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPST
• Voltage rating must equal or exceed 125V AC
• Current rating must equal or exceed 15A AC
• Switch function must be On-Off operation

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount
• Termination style must be Solder Lug
• Panel cutout dimensions must be Circular - 12.40mm Dia
• Bushing thread must be 15/32-32
• Actuator type must be Standard Round

Environmental Compatibility Requirements:

• Operating temperature range must encompass or exceed -40°C to 71°C
• Ingress protection rating should maintain sealed characteristics

The substitute part 11TS115-2 satisfies all electrical and mechanical compatibility criteria, with enhanced current rating (20A) and extended low-temperature operating range (-54°C).

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (31NT92-2): The Honeywell 31NT92-2 is the preferred selection for new designs and applications requiring current production status. This part maintains active product lifecycle status with established supply availability (801 units in stock). The part carries standard compliance certifications (EAR99, HTSUS 8536.50.9065) and MSL Level 1 rating.

Substitute Part Selection (11TS115-2): The Honeywell 11TS115-2 serves as a functional equivalent for applications where the primary part becomes unavailable. This substitute provides identical electrical and mechanical interface compatibility with the following distinctions:

• Current Rating Enhancement: 20A AC rating provides 33% additional current capacity beyond the 15A requirement of the primary part
• Temperature Range Extension: Operating range of -54°C to 71°C extends low-temperature capability by 14°C compared to the primary part
• Product Lifecycle Status: Classified as obsolete, indicating this part is no longer in active production

The substitute part carries RoHS Compliance certification and maintains identical ECCN and HTSUS classifications as the primary part.

Selection Criteria:

• Use 31NT92-2 for new designs and applications requiring active product status
• Use 11TS115-2 only when 31NT92-2 becomes unavailable and application requirements permit operation with a part in obsolete status
• Both parts are electrically and mechanically interchangeable within the specified parameter ranges

Frequently Asked Questions (FAQ)

Q: Can the 11TS115-2 directly replace the 31NT92-2 in existing applications?

A: Yes. Both parts share identical SPST circuit configuration, 125V AC voltage rating, panel mount mechanical interface (12.40mm circular cutout, 15/32-32 bushing thread), solder lug termination, and non-illuminated actuator design. The 11TS115-2 provides higher current rating (20A versus 15A) and extended low-temperature operation (-54°C versus -40°C), making it functionally compatible for direct substitution.

Q: What is the significance of the product status difference between these parts?

A: The 31NT92-2 maintains active product status, indicating ongoing manufacturing and supply availability. The 11TS115-2 is classified as obsolete, meaning it is no longer in active production. Active status parts are preferred for new designs. Obsolete parts should be considered only when the active part becomes unavailable.

Q: Are there mechanical installation differences between these parts?

A: No. Both parts use identical panel mount specifications: 12.40mm diameter circular cutout and 15/32-32 bushing thread. Actuator length differs by 0.51mm (17.02mm versus 16.51mm), which is negligible for standard panel mount applications and does not affect installation compatibility.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications. The 11TS115-2 additionally carries RoHS Compliance certification. Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the electrical difference between these parts?

A: The primary electrical difference is current rating. The 31NT92-2 is rated for 15A AC, while the 11TS115-2 is rated for 20A AC. Both operate at 125V AC with identical SPST on-off switching function. The higher current rating of the substitute part does not create compatibility issues in applications designed for 15A operation.

Q: Are there temperature operating range considerations for substitution?

A: The 11TS115-2 extends the low-temperature operating limit to -54°C compared to -40°C for the 31NT92-2. Both parts operate to 71°C maximum. Applications requiring operation below -40°C benefit from the substitute part's extended range. Applications within the -40°C to 71°C window operate identically with either part.

Q: What termination compatibility exists between these parts?

A: Both parts use solder lug termination, ensuring identical electrical connection methodology. No modifications to circuit board layouts or wiring harnesses are required when substituting between these parts.
