TS03CQE Slide Switch SPDT Equivalent & Substitute Parts

Part Overview

The TS03CQE is an active-status slide switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuit configuration with On-Off-On switching function. This component is designed for through-hole mounting applications requiring 1A at 120V AC or 28V DC operation. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or application requirements align with alternative electrical and mechanical specifications within the allowed parameter range for SPDT slide switches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS03CQE is determined by the following critical parameters:

Circuit Configuration: All substitutes must maintain SPDT topology with On-Off-On switching function to preserve circuit-level compatibility.

Mounting and Termination: Through-hole mounting with PC pin termination is required for PCB integration compatibility.

Voltage and Current Ratings: Substitute parts must support the application's voltage and current requirements. The TS03CQE operates at 1A/120V AC or 28V DC. Substitutes with lower current ratings (0.4VA) are acceptable only when the application does not exceed 0.4VA power handling. Voltage ratings must meet or exceed the application requirement.

Environmental Compliance: All substitutes must maintain ROHS3 compliance and operate within the specified temperature range (-30°C to 85°C minimum).

Contact Material and Finish: Silver or equivalent noble metal contacts ensure reliable signal transmission and corrosion resistance.

The three identified substitutes (1571982-4, AS13AP, AS13CP) meet these core criteria while offering alternative mechanical and electrical life specifications.

Parameter Comparison

Engineering Selection Recommendations

TS03CQE (Primary Part): Remains the preferred selection for applications requiring 1A at 120V AC operation. Active product status and full compliance certifications (ROHS3, REACH Unaffected) support continued use where inventory is available.

1571982-4 (TE Connectivity ALCOSWITCH): Suitable for applications operating at 20V or lower with current requirements not exceeding 0.4VA. This substitute offers extended electrical life (60,000 cycles) and active product status. Temperature range limitation (-20°C to 80°C) restricts use in applications requiring -30°C operation. ROHS3 compliance is confirmed; REACH status is vendor-undefined.

AS13AP (NKK Switches): Applicable for 28V DC applications with 0.4VA maximum current. Maintains full temperature range compatibility (-30°C to 85°C) and REACH compliance. Electrical life of 50,000 cycles and active product status support long-term reliability. Actuator length of 2.50mm differs from the primary part.

AS13CP (NKK Switches): Functionally equivalent to AS13AP with identical electrical specifications and compliance certifications. Distinguishing feature is the extended actuator length of 3.80mm, which may be required for specific mechanical envelope constraints. Active product status and full environmental compliance are maintained.

Frequently Asked Questions (FAQ)

Q: Can 1571982-4 replace TS03CQE in all applications?

A: No. The 1571982-4 is limited to 20V maximum and 0.4VA current rating. It is suitable only for applications operating at or below these levels. Applications requiring 120V AC operation must use the TS03CQE or equivalent 1A-rated alternatives. Additionally, the temperature range is restricted to -20°C to 80°C, excluding -30°C operation.

Q: What is the difference between AS13AP and AS13CP?

A: Both parts are electrically and functionally identical SPDT switches with 0.4VA at 28V DC/AC rating, 50,000-cycle electrical life, and full compliance certifications. The primary difference is actuator length: AS13AP features 2.50mm actuator length, while AS13CP provides 3.80mm actuator length. Selection depends on mechanical envelope and switch travel requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. TS03CQE, 1571982-4, AS13AP, and AS13CP all carry ROHS3 compliance certification, meeting regulatory requirements for hazardous substance restrictions.

Q: Can substitutes be used interchangeably in high-current applications?

A: No. The TS03CQE is rated for 1A operation, while all three substitutes are limited to 0.4VA. High-current applications (above 0.4VA) must use the TS03CQE or other 1A-rated SPDT switches. Using lower-rated substitutes in high-current applications will result in contact degradation and premature failure.

Q: What packaging differences exist among these parts?

A: TS03CQE is supplied in bulk packaging. 1571982-4 is supplied in bulk packaging. AS13AP and AS13CP are supplied in tray packaging. Packaging selection may affect procurement logistics and handling procedures but does not impact electrical or mechanical performance.

Q: Which substitute offers the longest operational life?

A: 1571982-4 provides the highest electrical life rating at 60,000 cycles, compared to 30,000 cycles for TS03CQE and 50,000 cycles for both AS13AP and AS13CP. However, this advantage applies only to applications within the 20V/0.4VA operating envelope.
