Equivalent & Substitute Parts for Honeywell 1TL11-1L Toggle Switch

Part Overview

The Honeywell 1TL11-1L is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 15A at 125V AC. This component features a locking lever actuator with environment-sealed ingress protection and screw terminal connections. The 1TL11-1L is classified as obsolete product status, necessitating identification of equivalent substitute components for ongoing procurement and system maintenance.

• Voltage rating: 125V AC

Mechanical Specifications:

• Mounting type: Panel Mount
• Actuator type: Locking Lever
• Actuator length: 26.67mm
• Panel cutout dimensions: Circular - 12.40mm Dia
• Bushing thread: 15/32-32
• Termination style: Screw Terminal

Environmental & Compliance:

• Ingress protection: Environment Sealed
• Operating temperature range: -65°C to 71°C
• RoHS compliance status

The substitute part 1TL1-1A meets all specified parameters and belongs to the same TL series, providing direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 1TL1-1A serves as the direct substitute for the obsolete 1TL11-1L. Both components are manufactured by Honeywell Sensing and Productivity Solutions and share identical electrical, mechanical, and environmental specifications. The primary distinction is product status: the 1TL11-1L is obsolete while the 1TL1-1A maintains active production status.

Selection of the 1TL1-1A is supported by:

• Complete parameter equivalence across all electrical ratings (15A, 125V AC, SPDT configuration)
• Identical mechanical interface specifications (panel cutout, bushing thread, actuator dimensions)
• Matching environmental sealing and operating temperature range
• Equivalent RoHS compliance and moisture sensitivity classification
• Active product status ensuring continued availability and supply chain support

Frequently Asked Questions (FAQ)

Q: Can the 1TL1-1A directly replace the 1TL11-1L in existing installations?

A: Yes. The 1TL1-1A provides complete functional and mechanical compatibility. All electrical parameters, panel mounting dimensions, and environmental specifications are identical. No circuit modifications or mechanical adaptations are required.

Q: What is the difference between the 1TL11-1L and 1TL1-1A?

A: The components are electrically and mechanically equivalent. The primary difference is product status: 1TL11-1L is obsolete, while 1TL1-1A is active production. The 1TL1-1A may be supplied in bulk packaging.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical RoHS compliance status and moisture sensitivity classification (MSL 1). Both are rated for the same operating temperature range (-65°C to 71°C) and environmental sealing specifications.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: circuit configuration (SPDT), switch function (On-Off-On), current rating (15A AC), voltage rating (125V AC), mounting type (panel mount), actuator type and length (locking lever, 26.67mm), panel cutout dimensions (12.40mm circular), bushing thread (15/32-32), and termination style (screw terminal).

Q: Is the 1TL1-1A available in the same packaging as the 1TL11-1L?

A: The 1TL1-1A is supplied in bulk packaging, whereas the 1TL11-1L packaging specification was not provided. Verify packaging requirements for your procurement process.
