Omron Z-01H SPDT Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The Omron Z-01H is an SPDT (Single Pole Double Throw) snap action switch designed for chassis mount applications with solder lug termination. This switch operates at 125V AC / 30V DC with a current rating of 100mA and features a round pin plunger actuator. The Z-01H maintains active product status and is RoHS compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when addressing application requirements for higher current ratings, extended temperature ranges, or alternative termination styles while maintaining core SPDT functionality and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Z-01H is determined by the following core parameters:

• Circuit Configuration: All substitutes must maintain SPDT topology
• Switch Function: All substitutes must operate as On-Momentary
• Actuator Type: All substitutes must use round pin plunger actuation
• Mounting Type: All substitutes must support chassis mount installation
• Mechanical Compatibility: Operating position and travel specifications must align with mechanical envelope requirements
• Compliance: All substitutes must maintain RoHS compliance and MSL 1 rating

The three substitute parts listed below meet these criteria while offering variations in current rating capacity, voltage handling, termination style, and operating temperature range. These variations allow selection based on specific application demands while preserving functional interchangeability within the SPDT snap action switch category.

Engineering Selection Recommendations

Z-01H (Primary Selection) The Z-01H remains the recommended choice for new designs. Active product status ensures long-term availability and supply chain stability. Solder lug termination provides direct PCB integration. The 100mA current rating and 30V DC voltage specification suit low-signal switching applications. Operating temperature range of -25°C to 80°C covers standard industrial environments.

BZ-3R (Preferred Substitute) The BZ-3R offers the closest functional alignment with the Z-01H while providing enhanced specifications. Active product status matches the primary part. Solder lug termination maintains installation compatibility. The 15A AC / 500mA DC current capacity accommodates higher-load applications. Extended DC voltage rating (125V) and operating temperature range (-55°C to 85°C) support broader environmental conditions. Mechanical life specification (20,000,000 cycles) matches the Z-01H.

BE-2R2425 and BM-1R369-A41 (Limited Substitution) Both Honeywell parts carry obsolete product status, limiting their suitability for new applications. Screw terminal termination requires circuit board redesign compared to solder lug configuration. BE-2R2425 provides 25A AC capacity with extended temperature range (-55°C to 121°C). BM-1R369-A41 offers 22A AC capacity with operating position matching the Z-01H (0.625"). These parts remain viable only for legacy system maintenance or replacement scenarios where supply exists.

Frequently Asked Questions (FAQ)

Q: Can the BZ-3R directly replace the Z-01H in existing designs? A: Mechanical and electrical compatibility exists for SPDT snap action switching function. Verify that the application does not depend on the Z-01H's specific 30V DC maximum rating, as the BZ-3R supports 125V DC. Solder lug termination on both parts ensures installation compatibility without circuit board modification.

Q: Why do the Honeywell substitutes use screw terminals instead of solder lugs? A: Screw terminal design reflects Honeywell's product architecture for the BE and BM series. Circuit board integration requires terminal pad redesign. Solder lug termination (Z-01H, BZ-3R) provides direct through-hole mounting without additional hardware.

Q: What is the significance of product status (Active vs. Obsolete)? A: Active status indicates ongoing manufacturing and supply chain support. Obsolete status signals end-of-life production, with availability limited to existing inventory. New designs should prioritize active parts (Z-01H, BZ-3R) to ensure long-term component availability and support.

Q: Are all substitute parts RoHS compliant? A: Yes. The Z-01H, BE-2R2425, BM-1R369-A41, and BZ-3R all carry RoHS compliance certification with MSL 1 (unlimited moisture sensitivity level), meeting environmental and regulatory requirements for industrial applications.

Q: How do current ratings affect substitution decisions? A: The Z-01H operates at 100mA, suitable for low-current signal switching. Substitutes offer higher current capacity (BZ-3R: 15A AC / 500mA DC; BE-2R2425: 25A AC; BM-1R369-A41: 22A AC). Select based on actual circuit current requirements. Oversizing current capacity does not degrade performance in lower-current applications.

Q: What mechanical differences exist between these parts? A: Operating position varies slightly (Z-01H, BM-1R369-A41, BZ-3R: 0.625"; BE-2R2425: 0.640"). All parts maintain 20,000,000 mechanical life cycles. Pretravel and differential travel specifications differ across models. Verify mechanical envelope compatibility within the specific application chassis.
