Honeywell 5HM11 SPDT Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The Honeywell 5HM11 is an SPDT (Single Pole Double Throw) snap action switch with chassis mount configuration, rated for 2.5A AC at 115V and 4A DC at 28V. This switch features a straight lever actuator and solder lug termination, designed for On-Momentary operation. The part is currently Active in production status with 789 units in stock inventory.

Substitute parts become necessary when the 5HM11 reaches end-of-life, when alternative sourcing is required for supply chain continuity, or when application requirements permit operation within the electrical and mechanical parameter ranges of equivalent alternatives. The substitute parts listed below maintain SPDT circuit configuration and chassis mount design while offering different current and voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Honeywell 5HM11 is determined by the following criteria:

Circuit Configuration: All substitute parts must maintain SPDT circuit topology to preserve switching logic in the application.

Mounting Type: All substitutes must be chassis mount to ensure mechanical compatibility with existing enclosure designs.

Termination Style: All substitutes must use solder lug termination for compatibility with existing PCB or wiring harness connections.

Actuator Type: All substitutes must feature a straight lever actuator to maintain consistent operator interface and actuation geometry.

Switch Function: All substitutes must operate in On-Momentary mode to match the original switching behavior.

Electrical Ratings: Substitute parts may have different current and voltage ratings. An application may use a substitute if the substitute's ratings equal or exceed the application's actual operating requirements. The substitute must not be operated below its minimum rated values or above its maximum rated values.

Environmental Compliance: All substitute parts must maintain RoHS compliance status and MSL rating of 1 (Unlimited) to ensure regulatory and reliability equivalence.

The three substitute parts listed below satisfy all mandatory criteria and are grouped as direct functional equivalents to the 5HM11.

Parameter Comparison

Engineering Selection Recommendations

DB1C-A1LB (ZF Electronics): This substitute is suitable for applications where AC current requirements do not exceed 5A at 125V or DC current does not exceed 1A at 48V. The DB1C-A1LB offers higher AC voltage rating (125V vs. 115V) and higher DC voltage rating (48V vs. 28V) compared to the 5HM11. Operating force is significantly lower at 60gf. This part is ROHS3 compliant and maintains MSL 1 rating. Inventory availability is high at 22,513 units.

DC2C-A1LB (ZF Electronics): This substitute is suitable for applications where AC current requirements do not exceed 10A at 125V. The DC2C-A1LB provides the highest AC current rating among the three substitutes. DC voltage and current ratings are not specified for this part. Operating force is 153gf, closer to the 5HM11 specification. This part is ROHS3 compliant and maintains MSL 1 rating. Inventory availability is 989 units. Ingress protection rating is IP67 (Dust Tight, Waterproof).

DC3C-A1LB (ZF Electronics): This substitute is suitable for applications where AC current requirements do not exceed 100mA at 125V. The DC3C-A1LB has the lowest current rating and is appropriate only for low-power signal switching applications. Operating force is 82gf. This part is ROHS3 compliant and maintains MSL 1 rating. Inventory availability is high at 14,397 units. Ingress protection rating is IP67 (Dust Tight, Waterproof).

All three substitutes are Active products with current production status and maintain regulatory compliance equivalent to the 5HM11.

Frequently Asked Questions (FAQ)

Q: Can the DB1C-A1LB replace the 5HM11 in all applications?

A: The DB1C-A1LB is a functional substitute only if the application's actual AC current requirement does not exceed 5A and actual DC current does not exceed 1A. The DB1C-A1LB has higher voltage ratings (125V AC, 48V DC) than the 5HM11 (115V AC, 28V DC), making it suitable for higher-voltage circuits. The lower operating force (60gf vs. 198gf) means the actuator requires less force to engage.

Q: What is the difference between the three ZF Electronics substitutes?

A: The three ZF Electronics substitutes differ primarily in current rating capacity. The DB1C-A1LB is rated for 5A AC and 1A DC. The DC2C-A1LB is rated for 10A AC with no DC rating specified. The DC3C-A1LB is rated for only 100mA AC and is intended for low-power applications. All three maintain SPDT configuration, On-Momentary function, and chassis mount design.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: Yes. The 5HM11 has an operating position of 0.330" (8.4mm), while all three ZF Electronics substitutes have an operating position of 0.420" (10.7mm). This difference in actuator travel distance may affect mechanical fit within the enclosure or control panel. Verify that the larger operating position does not interfere with the mechanical design of the application.

Q: Do the substitute parts have different ingress protection ratings?

A: Yes. The 5HM11 does not specify an ingress protection rating. The DB1C-A1LB is rated IP50 (Dust Protected). The DC2C-A1LB and DC3C-A1LB are both rated IP67 (Dust Tight, Waterproof). Higher ingress protection ratings provide better environmental sealing and may be beneficial in harsh operating conditions.

Q: What is the operating temperature range difference?

A: The 5HM11 operates from -184°C to 164°C, providing an exceptionally wide temperature range. All three ZF Electronics substitutes operate from -40°C to 120°C, a narrower range. If the application requires operation outside the -40°C to 120°C window, the 5HM11 must be used and substitution is not possible.

Q: Are all substitutes RoHS compliant?

A: Yes. The 5HM11 is RoHS Compliant. All three substitutes are ROHS3 Compliant. Both compliance levels are acceptable for regulatory purposes. All parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute has the best inventory availability?

A: The DB1C-A1LB has the highest inventory with 22,513 units in stock. The DC3C-A1LB has 14,397 units. The DC2C-A1LB has the lowest availability at 989 units. The original 5HM11 has 789 units in stock.
