Equivalent & Substitute Parts for ZX40E50E01

Part Overview

The ZX40E50E01 is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions. This through-hole, right-angle mounted switch is rated for 3A at 125V AC with a lever-actuated simulated roller mechanism. The product is classified as obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZX40E50E01 requires strict alignment of electrical and mechanical parameters. The primary criteria for determining substitute compatibility are:

Electrical Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Current and voltage ratings
• Operating temperature range

Mechanical Parameters:

• Actuator type (Lever-based)
• Mounting configuration (Through Hole, Right Angle)
• Termination style (PC Pin)
• Physical dimensions and travel specifications

The identified substitute part DG23-B3RA from ZF Electronics shares the same circuit topology (SPDT), switch function (On-Momentary), mounting type (Through Hole, Right Angle), and termination style (PC Pin). However, this substitute operates at significantly reduced electrical ratings (50mA DC at 30V) compared to the original specification (3A AC at 125V AC), making it suitable only for applications with lower power requirements.

Parameter Comparison

Engineering Selection Recommendations

The ZX40E50E01 and DG23-B3RA are both classified as obsolete products. Both components maintain RoHS compliance (RoHS and ROHS3 respectively) and share identical mechanical mounting characteristics and circuit topology.

Selection between these parts must be based on application electrical requirements. The ZX40E50E01 is specified for high-current AC applications (3A at 125V AC), while the DG23-B3RA is rated for low-current DC applications (50mA at 30V DC). These electrical specifications are not interchangeable.

The DG23-B3RA provides extended electrical life (200,000 cycles versus 10,000 cycles) but operates within a narrower temperature range (-25°C to 85°C versus -40°C to 120°C). Physical dimensions differ slightly, with the DG23-B3RA operating position at 0.488" (12.4mm) compared to 0.437" (11.1mm) for the ZX40E50E01.

Both components feature PC pin termination suitable for through-hole PCB mounting in right-angle configuration. The DG23-B3RA includes IP40 ingress protection, whereas the ZX40E50E01 does not specify this parameter.

Frequently Asked Questions (FAQ)

Q: Can the DG23-B3RA directly replace the ZX40E50E01 in all applications?

A: No. The DG23-B3RA operates at significantly lower electrical ratings (50mA DC at 30V DC) compared to the ZX40E50E01 (3A AC at 125V AC). Substitution is only valid for applications with electrical requirements that fall within the DG23-B3RA specifications.

Q: What are the key mechanical compatibility factors between these parts?

A: Both parts share identical mounting type (Through Hole, Right Angle), termination style (PC Pin), and circuit configuration (SPDT). Operating position differs by approximately 0.051" (1.3mm), and operating force differs by 5gf. These mechanical differences may affect mechanical fit and actuation feel in the application.

Q: How do the temperature operating ranges compare?

A: The ZX40E50E01 operates from -40°C to 120°C, while the DG23-B3RA operates from -25°C to 85°C. The ZX40E50E01 provides a wider temperature envelope, particularly at low temperatures. Applications requiring operation below -25°C or above 85°C cannot use the DG23-B3RA as a substitute.

Q: What is the significance of the electrical life difference?

A: The ZX40E50E01 is rated for 10,000 electrical cycles, while the DG23-B3RA is rated for 200,000 electrical cycles. This difference reflects the different electrical load classes. The DG23-B3RA's higher cycle rating is appropriate for low-current switching, while the ZX40E50E01's lower rating reflects its higher current capacity.

Q: Are both parts RoHS compliant?

A: Yes. The ZX40E50E01 is RoHS Compliant, and the DG23-B3RA is ROHS3 Compliant. Both meet current environmental compliance requirements for electronic components.

Q: What does the IP40 ingress protection rating on the DG23-B3RA indicate?

A: IP40 protection indicates the part is protected against solid objects larger than 1mm and provides no protection against liquid ingress. The ZX40E50E01 does not specify an ingress protection rating. Applications requiring sealed or liquid-resistant switches should evaluate this parameter.
