Honeywell 102TL2-50K Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The Honeywell 102TL2-50K is a panel-mount toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 7.5A at 115V AC and 30V DC. This component features a locking lever actuator with environment-sealed ingress protection and is classified as obsolete. Due to its obsolete product status, identification of equivalent substitute parts is necessary for ongoing system maintenance and new design implementations where DPDT toggle switch functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 102TL2-50K is determined by the following critical parameters that must remain compatible:

Mandatory Compatibility Parameters:

• Circuit configuration: DPDT
• Switch function: On-On-Mom
• Mounting type: Panel Mount
• Actuator type: Locking Lever
• Actuator length: 26.67mm
• Panel cutout diameter: 12.40mm
• Bushing thread: 15/32-32
• Ingress protection: Environment Sealed
• Operating temperature range: -65°C to 71°C
• RoHS compliance status

Electrical Parameters Subject to Substitution:

• Current rating may be equal to or greater than 7.5A
• Voltage ratings may be equal to or greater than the original specifications
• Termination style may differ if mechanical and electrical interfaces remain compatible

The substitute part 2TL1-50K meets all mandatory compatibility parameters while providing enhanced electrical ratings (10A AC at 125V) and active product status.

Parameter Comparison

Engineering Selection Recommendations

For 102TL2-50K Replacement:

The Honeywell 2TL1-50K is a direct functional substitute for the obsolete 102TL2-50K. Both components share identical mechanical interfaces, circuit topology, and environmental specifications. The 2TL1-50K provides superior electrical ratings (10A AC at 125V versus 7.5A at 115V AC), ensuring compatibility with the original application while offering enhanced performance margin.

Product Status Consideration:

The 102TL2-50K is classified as obsolete, making the active-status 2TL1-50K the appropriate selection for new designs and ongoing production requirements. Both parts maintain RoHS compliance and identical operating temperature ranges (-65°C to 71°C).

Termination Difference:

The primary difference between these parts is the termination style: the 102TL2-50K uses IWTS (Insulated Wire Terminal Strip) termination, while the 2TL1-50K uses Screw Terminal termination. This difference requires evaluation of the specific circuit board or wiring harness design to ensure compatibility with the target application.

Frequently Asked Questions (FAQ)

Q: Can the 2TL1-50K directly replace the 102TL2-50K in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for all critical parameters. However, the termination style difference (IWTS versus Screw Terminal) must be evaluated against the specific wiring or PCB interface design. If the original assembly uses IWTS connectors, a termination adapter or rewiring may be required.

Q: What is the significance of the higher current rating on the 2TL1-50K?

A: The 2TL1-50K is rated for 10A AC at 125V, compared to the 102TL2-50K's 7.5A at 115V AC. This higher rating provides additional electrical capacity and is fully backward-compatible with applications originally designed for the lower-rated component. No circuit modifications are necessary.

Q: Are both parts RoHS compliant?

A: Yes. Both the 102TL2-50K and 2TL1-50K are RoHS Compliant, meeting environmental and regulatory requirements for electronic component manufacturing and deployment.

Q: What is the operational temperature range for both parts?

A: Both components operate across the identical temperature range of -65°C to 71°C, ensuring consistent thermal performance in equivalent applications.

Q: Why is the 102TL2-50K listed as obsolete?

A: The 102TL2-50K has reached end-of-life status in Honeywell's product portfolio. The 2TL1-50K represents the active-status equivalent, ensuring long-term availability and supply chain continuity for DPDT toggle switch applications.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a circular panel cutout of 12.40mm diameter and use the same 15/32-32 bushing thread, confirming mechanical interchangeability in panel-mount installations.
