SL1-HK Equivalent & Substitute Parts Reference

Part Overview

The SL1-HK is an active snap-action switch manufactured by Honeywell Sensing and Productivity Solutions. This SPDT (Single Pole Double Throw) switch is designed for chassis mount applications with connector termination and IP67 ingress protection. The component operates at 125V AC / 30V DC with a 100mA current rating and is classified as Active product status. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component procurement flexibility while maintaining circuit performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL1-HK is determined by strict alignment of the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Mom (On-Momentary)
• Voltage ratings must support minimum 125V AC and 30V DC operation
• Current rating must equal or exceed 100mA

Mechanical Compatibility Requirements:

• Actuator type must be Round (Pin Plunger)
• Mounting type must be Chassis Mount
• Ingress protection must maintain IP67 classification
• Operating force and release force must be within specified tolerances (1200gf operating / 500gf release)

Environmental & Compliance Requirements:

• Operating temperature range must encompass -10°C to 70°C minimum
• RoHS compliance status must be active (RoHS Compliant or ROHS3 Compliant)
• Moisture sensitivity level must be 1 (Unlimited)

The ZC-D55 manufactured by Omron Automation and Safety meets all critical electrical and mechanical parameters for substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

SL1-HK Selection Criteria: The SL1-HK remains the primary component choice when connector termination is required and current requirements are limited to 100mA maximum. This part maintains Active product status with RoHS Compliant certification and is available in inventory (941 Pcs). The connector termination style differentiates this component for applications requiring quick-disconnect capabilities.

ZC-D55 Selection Criteria: The ZC-D55 qualifies as an equivalent substitute when higher current capacity (10A AC / 6A DC) is required within the same electrical and mechanical parameter envelope. This component features screw terminal termination instead of connector termination. The ZC-D55 maintains ROHS3 Compliant status, extended operating temperature range (-10°C to 80°C), and documented electrical life (500,000 cycles) and mechanical life (10,000,000 cycles) specifications. Inventory availability is 715 Pcs.

Termination Style Consideration: The primary distinction between these components is termination method. The SL1-HK uses connector termination; the ZC-D55 uses screw terminal termination. This difference requires mechanical interface verification during component selection.

Frequently Asked Questions (FAQ)

Q: Can the ZC-D55 directly replace the SL1-HK in all applications?

A: The ZC-D55 is electrically and mechanically compatible with the SL1-HK based on circuit configuration, voltage ratings, current capacity, actuator type, mounting type, and ingress protection. However, termination style differs: SL1-HK uses connector termination while ZC-D55 uses screw terminal termination. Verify that your circuit board or wiring harness accommodates screw terminal connection before substitution.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility requires: SPDT circuit configuration, On-Mom switch function, minimum 125V AC / 30V DC voltage support, and current rating equal to or exceeding 100mA. The ZC-D55 meets all these requirements with higher current capacity (10A AC / 6A DC).

Q: Are there differences in mechanical performance between these components?

A: Both components share identical operating force (1200gf) and release force (500gf). Operating position differs: SL1-HK operates at 1.000" (25.4mm) while ZC-D55 operates at 1.276" (32.4mm). Pretravel is identical at 0.060" (1.5mm). Differential travel and overtravel show minor variations. These mechanical differences may affect mechanical interface design.

Q: What compliance certifications apply to each component?

A: The SL1-HK holds RoHS Compliant certification. The ZC-D55 holds ROHS3 Compliant certification and is REACH Affected. Both components have Moisture Sensitivity Level 1 (Unlimited) and ECCN EAR99 classification.

Q: Which component should be selected for new designs?

A: Component selection depends on termination requirements and current specifications. For connector termination applications with 100mA current requirements, select SL1-HK. For screw terminal applications or higher current requirements (up to 10A AC / 6A DC), select ZC-D55. Both components are Active status with current inventory availability.
