SW237CD13 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The SW237CD13 is an APEM Inc. toggle switch featuring Single Pole Double Throw (SPDT) circuitry with momentary-off-momentary (Mom-Off-Mom) switching function. This through-hole, right-angle mounted component is rated for 0.4VA at 20V AC/DC operation and is designed for applications requiring sealed, non-illuminated toggle actuation. The part is currently active in production with 797 units in stock. Substitute parts are identified when equivalent electrical ratings, circuit configurations, and mechanical mounting specifications align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SW237CD13 are qualified based on the following critical parameters that must match or exceed the original specification:

Mandatory Matching Parameters:

• Circuit Configuration: SPDT
• Switch Function: Mom-Off-Mom
• Current Rating: 0.4VA (AC/DC)
• Voltage Rating - AC: 20V minimum
• Voltage Rating - DC: 20V minimum
• Mounting Type: Through Hole, Right Angle
• Termination Style: PC Pin
• Actuator Type: Standard Round
• Non-Illuminated configuration

Allowable Variations:

• Actuator Length: Variations permitted within mechanical envelope constraints
• Operating Temperature Range: Substitute may exceed original range
• Electrical Life Cycles: Substitute may exceed original rating
• Ingress Protection: Substitute may provide enhanced protection
• Actuator Material: Variations permitted if electrical performance maintained
• Sealing Features: Substitute may provide enhanced sealing

The identified substitutes (100AWSP4T2B4M6RE and 7105SD9ABE) satisfy all mandatory parameters while offering comparable or enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

SW237CD13 (APEM Inc.) - Primary specification. ROHS3 compliant, active production status, 50,000 cycle electrical life rating. Suitable for standard industrial applications within specified temperature and voltage parameters.

100AWSP4T2B4M6RE (E-Switch) - Direct functional equivalent with extended operating temperature range (-30°C to 85°C) and IP67 ingress protection rating. Electrical life rated at 30,000 cycles. Shorter actuator length (7.62mm) requires mechanical envelope verification. ROHS3 compliant, active production status. Recommended for applications requiring enhanced environmental sealing.

7105SD9ABE (C&K) - Direct functional equivalent with extended operating temperature range (-30°C to 85°C) and 40,000 cycle electrical life rating. Actuator length (12.45mm) closely matches original specification. ROHS3 compliant, active production status. REACH affected status noted. Recommended for applications requiring extended temperature operation.

Selection between substitutes depends on specific mechanical envelope constraints (actuator length), environmental protection requirements (IP67 rating), and regulatory compliance needs (REACH status).

Frequently Asked Questions (FAQ)

Q: Can 100AWSP4T2B4M6RE replace SW237CD13 in all applications?

A: Electrical and circuit specifications are equivalent. The 7.62mm actuator length differs from the original 13.30mm specification. Mechanical envelope compatibility must be verified for the specific application before substitution.

Q: What is the significance of the IP67 rating on the E-Switch substitute?

A: IP67 designation indicates dust-tight and waterproof protection. The original SW237CD13 does not specify ingress protection. The E-Switch substitute provides enhanced environmental sealing suitable for applications exposed to moisture or particulate contamination.

Q: Are all three parts ROHS3 compliant?

A: Yes. SW237CD13, 100AWSP4T2B4M6RE, and 7105SD9ABE are all ROHS3 compliant. The C&K part (7105SD9ABE) carries REACH affected status, which may impact supply chain considerations in certain regulatory jurisdictions.

Q: How do electrical life ratings compare?

A: SW237CD13 is rated for 50,000 cycles, 7105SD9ABE for 40,000 cycles, and 100AWSP4T2B4M6RE for 30,000 cycles. Application duty cycle requirements determine whether lower-rated substitutes are acceptable.

Q: Are the operating temperature ranges interchangeable?

A: The original SW237CD13 operates from -20°C to 85°C. Both substitutes extend the lower temperature limit to -30°C. If the application operates only within the original -20°C to 85°C range, all three parts are functionally equivalent in this parameter.

Q: What packaging format is available for these parts?

A: All three parts are supplied in bulk packaging. SW237CD13 has 797 units in stock, 100AWSP4T2B4M6RE has 1221 units, and 7105SD9ABE has 749 units available.
