Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2TL11-50K is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Current rating (11A AC / 18A DC), voltage rating (125V AC / 28V DC), and circuit configuration (DPDT) must be identical.

Mechanical Parameters: Mounting type (panel mount), actuator type (locking lever), actuator length (26.67mm), termination style (screw terminal), panel cutout dimensions (circular 12.40mm diameter), and bushing thread (15/32-32) must match exactly.

Environmental & Compliance Parameters: Ingress protection (environment sealed), operating temperature range (-65°C to 71°C), and RoHS compliance status must be maintained.

Switch Function: The On-On-Mom function must be preserved.

The substitute part 2TL11-50E meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 2TL11-50E is a direct substitute for the 2TL11-50K. Both parts are manufactured by Honeywell Sensing and Productivity Solutions and share identical electrical, mechanical, and environmental specifications. The primary distinction is product status: the 2TL11-50K is obsolete while the 2TL11-50E maintains active status.

For new designs or component replenishment, the 2TL11-50E is the appropriate selection. Both parts maintain RoHS compliance and identical MSL ratings, ensuring regulatory and manufacturing process compatibility. The 2TL11-50E is available in bulk packaging with higher inventory levels (1012 pieces in stock versus 631 pieces for the 2TL11-50K).

Frequently Asked Questions (FAQ)

Q: Can the 2TL11-50E replace the 2TL11-50K in existing applications?
