TS01AKE Slide Switch SPDT Equivalent & Substitute Parts

Part Overview

The TS01AKE is a slide switch manufactured by C&K with SPDT (Single Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This component features through-hole, right-angle mounting with gold-plated copper alloy contacts and epoxy-sealed terminals. The part is currently obsolete, with 676 units in stock. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to ensure design continuity and long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on electrical parameter compatibility with the TS01AKE:

Direct Electrical Equivalents (0.4VA @ 20V): Parts matching the exact current and voltage ratings with identical circuit configuration, mounting type, and termination style. These parts maintain full functional compatibility without circuit redesign.

Higher-Rated Alternatives (3A @ 120-125V): Parts with superior current and voltage ratings that operate within the TS01AKE's electrical envelope. These parts are suitable for applications where the original specifications are not fully utilized and higher performance margins are acceptable.

Key Parameters for Substitution Compatibility:

SPDT circuit configuration (mandatory)
Through-hole, right-angle mounting (mandatory)
PC pin termination (mandatory)
Current rating ≥ 0.4VA
Voltage rating ≥ 20V AC/DC
Operating temperature range overlap with -30°C to 85°C

Engineering Selection Recommendations

Primary Recommendation - TS01APE (C&K): This part is the direct active equivalent from the original manufacturer. It maintains identical electrical specifications, mechanical dimensions, and operating temperature range as the TS01AKE. Active product status ensures long-term availability and supply chain continuity.

Secondary Recommendation - 500ASSP1M6RE (E-Switch): Provides direct electrical equivalence with 0.4VA @ 20V rating and identical mechanical mounting. Active status and high inventory (7,517 units) support reliable sourcing. Electrical life of 30,000 cycles is lower than the original specification but remains suitable for most applications.

Alternative - AS12AH (NKK Switches): Offers higher voltage rating (28V) with identical current capacity and gold-plated contacts. Suitable for applications requiring enhanced voltage margin. Mechanical dimensions differ slightly (2.50mm actuator length vs. 3.10mm), requiring PCB layout verification.

Higher-Performance Options - 48BFSP1M6QT or 500ASSP1M6QE: These 3A-rated parts provide significant performance headroom for applications where higher current capacity is beneficial. Both maintain identical mechanical mounting and operating temperature range. Silver contact finish differs from the original gold finish; verify compatibility with circuit requirements.

Compliance Consideration: All recommended substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can TS01APE directly replace TS01AKE without PCB modification? A: Yes. TS01APE maintains identical electrical ratings (0.4VA @ 20V), mechanical dimensions (3.10mm actuator, 3.05mm travel), and mounting configuration (through-hole, right-angle, PC pin termination). No circuit or layout changes are required.

Q: What is the primary difference between direct equivalents and higher-rated alternatives? A: Direct equivalents (TS01APE, 500ASSP1M6RE, AS12AH) match the 0.4VA @ 20V specification exactly. Higher-rated alternatives (48BFSP1M6QT, 500ASSP1M6QE) provide 3A @ 120-125V capacity, suitable only if the application can tolerate different contact finish (silver vs. gold) and lower electrical life cycles.

Q: Does actuator length variation affect compatibility? A: Actuator length differences (2.50mm to 3.80mm) may impact mechanical clearance and user interface feel. Verify PCB layout and enclosure design accommodate the selected actuator length. Parts with identical 3.10mm length (TS01APE, 48BFSP1M6QT, 500ASSP1M6QE) provide drop-in compatibility.

Q: Are there packaging differences between substitutes? A: Yes. TS01AKE and TS01APE use standard packaging. E-Switch 500RSP1S1M6RE ships in trays; NKK AS12AH and AS12CH ship in trays. Verify packaging compatibility with assembly processes and inventory management systems.

Q: Why do some substitutes have lower electrical life ratings? A: Grayhill 48B series and E-Switch 500A series specify 30,000 cycles versus the original 60,000 cycles. This reflects different design approaches and contact material selection. For applications with moderate switching frequency, 30,000 cycles remains adequate for typical product lifespans.

Q: Can AS12AH replace TS01AKE if voltage rating is higher? A: AS12AH operates at 28V AC/DC versus TS01AKE's 20V, providing voltage margin. However, actuator length is 2.50mm (vs. 3.10mm) and switch travel is 2.50mm (vs. 3.05mm). Mechanical compatibility must be verified before selection.

Q: What compliance certifications apply to all substitutes? A: All recommended parts maintain ROHS3 compliance and MSL 1 (unlimited moisture sensitivity level) rating. REACH status is unaffected for all parts. ECCN classification is EAR99 across all options.
