Honeywell 27ET2-6-P Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The Honeywell 27ET2-6-P is a panel-mount toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 7A DC at 28V. This switch features a locking lever actuator with magnetic hold functionality and is designed for environment-sealed applications. The part is classified as obsolete, making identification of equivalent active alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 27ET2-6-P is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Circuit configuration (DPDT), switch function (Mom-On-Mom), current rating (7A DC), and voltage rating (28V DC) must be identical.

Mechanical Specifications: Mounting type (Panel Mount), actuator type (Locking Lever), actuator length (26.92mm), panel cutout dimensions (12.40mm circular), and bushing thread (15/32-32) must match exactly.

Environmental & Operational: Ingress protection (Environment Sealed), magnetic hold feature, and operating temperature range (-65°C to 71°C) must be maintained.

Compliance: RoHS compliance and MSL rating must be equivalent or superior.

The 27ET2-6-E meets all substitution criteria and is classified as an active product, providing continuity for applications currently using the obsolete 27ET2-6-P.

Parameter Comparison

Engineering Selection Recommendations

The 27ET2-6-E is the direct equivalent for the obsolete 27ET2-6-P. 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 The primary distinction is product status: the 27ET2-6-P is obsolete while the 27ET2-6-E is active.

For new designs and ongoing system support, the 27ET2-6-E should be specified. Both parts maintain RoHS compliance and MSL Level 1 rating, ensuring regulatory and environmental compatibility. The difference in packaging (standard versus bulk) does not affect functional or mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 27ET2-6-E directly replace the 27ET2-6-P in existing applications?

A: Yes. The 27ET2-6-E is electrically and mechanically identical to the 27ET2-6-P. All electrical ratings, mechanical dimensions, mounting specifications, and environmental sealing are equivalent. Direct substitution is supported without circuit or mechanical modifications.

Q: What is the difference between the 27ET2-6-P and 27ET2-6-E?

A: The primary difference is product status. The 27ET2-6-P is classified as obsolete, while the 27ET2-6-E is an active product. Packaging differs (standard versus bulk), but this does not affect electrical or mechanical performance. All functional parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the 27ET2-6-P and 27ET2-6-E are RoHS compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What does the DPDT Mom-On-Mom configuration mean?

A: DPDT (Double Pole Double Throw) indicates the switch controls two independent circuits simultaneously. Mom-On-Mom (Momentary-On-Momentary) means the switch returns to a neutral position when released, requiring continuous actuation to maintain contact.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a 12.40mm circular panel cutout with a 15/32-32 bushing thread, ensuring mechanical interchangeability in panel-mount applications.

Q: What is the magnetic hold feature?

A: Magnetic hold provides detent positioning, allowing the switch actuator to remain in a selected position without continuous manual pressure. This feature is present in both the 27ET2-6-P and 27ET2-6-E.
