TL37P005000 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The TL37P005000 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 specific packaging requirements, ingress protection specifications, or supply chain considerations necessitate component substitution while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL37P005000 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT only
• Switch function: Mom-Off-Mom operation
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC minimum
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C minimum
• Electrical life: 30,000 cycles minimum
• RoHS3 compliance requirement

The ET05MD1CBE from C&K meets all mandatory electrical and mechanical criteria for direct substitution. Variations in actuator length, material composition, ingress protection rating, and packaging format do not affect core switching functionality within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the TL37P005000 and ET05MD1CBE maintain Active product status with full RoHS3 compliance and EAR99 export classification. Selection between these components should be based on:

• Packaging format requirements: TL37P005000 is supplied in Bulk packaging; ET05MD1CBE is supplied in Tray packaging
• Ingress protection specification: ET05MD1CBE provides IP57 rating (dust protected, waterproof); TL37P005000 has no specified ingress protection
• Actuator length tolerance: TL37P005000 features 5.30mm actuator length; ET05MD1CBE features 6.10mm actuator length
• Material specification: TL37P005000 uses brass with nickel plating; ET05MD1CBE uses brass with chrome plating
• Supply chain availability: Both components are in active stock

Frequently Asked Questions (FAQ)

Q: Can ET05MD1CBE replace TL37P005000 in all applications?

A: Yes, within the specified electrical and mechanical parameter envelope. The ET05MD1CBE meets all mandatory criteria: SPDT circuit, Mom-Off-Mom function, 0.4VA rating at 20V AC/DC, through-hole mounting with PC pin termination, -30°C to 85°C operating range, and 30,000 cycle electrical life. Physical differences in actuator length and material composition do not affect switching performance.

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

A: The TL37P005000 has a 5.30mm actuator length while ET05MD1CBE has a 6.10mm actuator length. This 0.80mm difference may impact panel cutout clearance and user interface ergonomics. Verify mechanical fit within your specific enclosure design before substitution.

Q: Does the ingress protection rating affect substitution eligibility?

A: The ET05MD1CBE provides IP57 ingress protection (dust protected, waterproof) while TL37P005000 has no specified ingress protection. If your application requires environmental sealing, ET05MD1CBE offers enhanced protection. If ingress protection is not required, this difference does not prevent substitution.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS3 compliant with EAR99 export classification and identical HTSUS coding (8536.50.9065). The ET05MD1CBE is REACH Affected while TL37P005000 is REACH Unaffected. Verify REACH compliance requirements for your specific application and end-use region.

Q: What packaging considerations apply to substitution?

A: TL37P005000 is supplied in Bulk packaging while ET05MD1CBE is supplied in Tray packaging. Confirm that your procurement and assembly processes accommodate the different packaging format before implementing substitution.
