TL37P000000 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The TL37P000000 is an APEM Inc. toggle switch featuring SPDT (Single Pole Double Throw) circuitry with momentary-off-momentary switching function. Rated for 0.4VA at 20V AC/DC, this through-hole mounted component is designed for applications requiring reliable electromechanical switching with epoxy sealed terminals. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Alternative models become necessary when addressing specific application requirements such as enhanced ingress protection, packaging format preferences, or supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL37P000000 is determined by strict equivalence across the following critical parameters:

Circuit configuration must remain SPDT with Mom-Off-Mom switching function. Current and voltage ratings must match at 0.4VA and 20V AC/DC respectively. Mounting type, actuator type, termination style, and operating temperature range must be identical. Electrical life specification of 30,000 cycles is mandatory. RoHS3 compliance and MSL rating of 1 (Unlimited) are required for regulatory and environmental compatibility.

The ET05MD1CBE from C&K meets all substitution criteria while introducing enhanced ingress protection (IP57) and alternative packaging format (Tray versus Bulk).

Parameter Comparison

Engineering Selection Recommendations

Both TL37P000000 and ET05MD1CBE maintain Active product status with full RoHS3 compliance, ensuring regulatory alignment for current and future applications. The TL37P000000 is suitable for standard environmental conditions with baseline epoxy sealed terminal protection. The ET05MD1CBE provides enhanced environmental protection through IP57 ingress rating, making it appropriate for applications with exposure to dust or moisture. Actuator length difference (5.30mm versus 6.10mm) must be evaluated against panel thickness and mechanical clearance requirements. Packaging format selection (Bulk versus Tray) depends on inventory management and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can ET05MD1CBE replace TL37P000000 in all applications? A: Electrical and functional compatibility is complete. Physical compatibility requires verification of actuator length (6.10mm versus 5.30mm) against panel cutout and mounting depth specifications.

Q: What is the significance of the IP57 rating on the ET05MD1CBE? A: IP57 classification indicates dust protection and waterproof operation. This specification is absent on the TL37P000000. Selection depends on environmental exposure requirements of the application.

Q: Are there compliance differences between these parts? A: Both parts are ROHS3 compliant. The ET05MD1CBE carries REACH Affected status while the TL37P000000 is REACH Unaffected. Application location and regulatory jurisdiction determine relevance of this distinction.

Q: How do packaging formats affect component selection? A: TL37P000000 is supplied in Bulk format; ET05MD1CBE in Tray format. Packaging choice impacts receiving inspection procedures, storage requirements, and assembly line integration but does not affect electrical performance.

Q: Are the electrical specifications identical? A: Yes. Both parts are rated 0.4VA at 20V AC/DC with SPDT Mom-Off-Mom configuration, 30,000 cycle electrical life, and -30°C to 85°C operating range.
