TL46P000000 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The TL46P000000 is an APEM Inc. toggle switch featuring DPDT (Double Pole Double Throw) circuitry with On-On 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.

Substitute parts become necessary when addressing supply chain constraints, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility within defined parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL46P000000 is determined by strict equivalence across the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must be 20V AC and 20V DC minimum
• Mounting type must be Through Hole
• Termination style must be PC Pin
• Actuator type must be Standard Round
• Operating temperature range must encompass -30°C ~ 85°C
• RoHS3 compliance is required

The following parts meet these substitution criteria: 200MDP1T2B2M2RE (E-Switch) and ET21MD1CBE (C&K).

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, qualifying them for equivalent substitution in applications meeting the specified electrical parameters.

The TL46P000000 and ET21MD1CBE both provide 60,000 electrical life cycles, suitable for high-cycle applications. The 200MDP1T2B2M2RE offers 30,000 cycles, appropriate for moderate-duty switching applications.

Actuator length variation (5.30mm, 5.33mm, 6.10mm) requires mechanical clearance verification within the target assembly. The ET21MD1CBE provides IP57 ingress protection, offering enhanced environmental sealing for applications requiring dust and moisture resistance.

REACH compliance status differs: TL46P000000 and 200MDP1T2B2M2RE are REACH Unaffected, while ET21MD1CBE is REACH Affected. Regulatory requirements for the end application determine applicability.

Frequently Asked Questions (FAQ)

Q: Can 200MDP1T2B2M2RE replace TL46P000000 in all applications?

A: Electrical substitution is valid. The 200MDP1T2B2M2RE meets all core electrical parameters (DPDT, 0.4VA, 20V AC/DC, On-On function). However, the reduced electrical life (30,000 vs. 60,000 cycles) requires assessment against application duty cycle requirements. Actuator length tolerance (5.33mm vs. 5.30mm) must be verified for mechanical fit.

Q: What is the significance of the actuator length differences?

A: Actuator length affects panel engagement depth and mechanical clearance. The TL46P000000 (5.30mm) and 200MDP1T2B2M2RE (5.33mm) are mechanically similar with negligible difference. The ET21MD1CBE (6.10mm) requires verification that panel cutout and surrounding components accommodate the longer actuator without interference.

Q: Does ET21MD1CBE's IP57 rating affect electrical compatibility?

A: No. IP57 classification indicates enhanced environmental sealing and does not alter electrical switching characteristics. This feature is beneficial for applications exposed to dust or moisture but is not required for standard indoor switching applications.

Q: Are packaging differences significant for procurement?

A: Packaging format (Bulk vs. Tray) affects handling, storage, and logistics but does not impact electrical or mechanical performance. Selection depends on assembly process requirements and inventory management practices.

Q: How do material differences in actuator plating affect performance?

A: Nickel plating (TL46P000000) and chrome plating (200MDP1T2B2M2RE, ET21MD1CBE) both provide corrosion resistance and durability. Selection depends on environmental exposure and specific application corrosion requirements.
