TS01CGF Slide Switch SPDT Equivalent & Substitute Parts

Part Overview

The TS01CGF is a slide switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) configuration with 3A current rating at 120V AC and 28V DC. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The switch is designed for through-hole mounting with PC pin termination, suitable for applications requiring reliable on-on switching functionality.

Substitute Part Grouping Explanation

Substitution of the TS01CGF is determined by the following critical parameters:

Primary Substitution Criteria:

Circuit configuration (SPDT required)
Switch function (On-On operation)
Mounting type (Through Hole)
Termination style (PC Pin)
Operating temperature range (-30°C to 85°C minimum)
RoHS3 compliance

Secondary Compatibility Factors:

Current rating (3A AC/DC preferred for direct replacement)
Voltage rating (120V AC / 28V DC preferred)
Actuator length (3.10mm nominal)
Contact material and finish (Silver/Gold preferred)

Substitute parts are grouped into two categories based on electrical ratings:

Group 1 - High Current Substitutes (3A Rating): Parts meeting the full 3A AC/DC specification with 120V AC / 28V DC ratings. These provide direct functional equivalence.

Group 2 - Lower Current Substitutes (0.4VA Rating): Parts with reduced current and voltage specifications. These are suitable only when application requirements permit lower electrical ratings.

Engineering Selection Recommendations

Direct Replacement (Preferred):

The 500ASSP1M2QE (E-Switch) and 48BFSP1M2QT (Grayhill Inc.) are the primary substitutes for the TS01CGF. Both maintain the 3A AC/DC current rating, 120V/125V AC specification, and 28V DC rating. Both are active products with ROHS3 compliance and identical operating temperature ranges. The 500ASSP1M2QE provides the closest electrical specification match with 120V AC rating identical to the original part.

Secondary Substitutes (Reduced Electrical Rating):

Parts including 48BFSP1M2RT, 4S1-FSP1-M2RE, 500RSP1S1M2RE, AS12AP, and AS12CP are suitable only when application requirements permit operation at 0.4VA with 20V to 28V specifications. These parts maintain SPDT configuration, through-hole mounting, and PC pin termination but operate at significantly lower current and voltage levels.

Limited Substitutes (Restricted Application):

SS12SBP2, SS12SBP4, and SS12SDP2 have reduced operating temperature ranges (-15°C to 60°C) and lower electrical life ratings (10,000 cycles). These parts are suitable only for applications with less demanding environmental and cycle life requirements.

All substitute parts listed maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and moisture sensitivity compatibility with the original TS01CGF specification.

Frequently Asked Questions (FAQ)

Q: Can the 500ASSP1M2QE directly replace the TS01CGF in all applications?

A: The 500ASSP1M2QE maintains equivalent SPDT configuration, 3A AC/DC current rating, 120V AC / 28V DC voltage specification, and identical operating temperature range. Mechanical compatibility requires verification of actuator length (both 3.10mm) and PC pin termination compatibility with the PCB layout.

Q: What is the primary difference between Group 1 and Group 2 substitutes?

A: Group 1 substitutes (48BFSP1M2QT and 500ASSP1M2QE) maintain the 3A AC/DC current rating and 120V AC specification of the original part. Group 2 substitutes operate at 0.4VA with reduced voltage ratings (20V to 28V). Selection depends on whether the application circuit requires the full 3A capacity or can operate within lower electrical specifications.

Q: Are the NKK Switches SS series parts suitable for high-current applications?

A: No. The SS12SBP2, SS12SBP4, and SS12SDP2 are rated for 100mA to 0.4VA maximum, significantly below the TS01CGF 3A specification. These parts are suitable only for low-signal switching applications. Additionally, their operating temperature range (-15°C to 60°C) is narrower than the original part.

Q: What packaging considerations apply to these substitutes?

A: The TS01CGF is supplied in bulk packaging. Substitute parts are available in bulk (Grayhill, Carling Technologies) or tray packaging (E-Switch, NKK Switches). Procurement and assembly processes may require adjustment based on packaging format.

Q: Do all substitutes maintain the same electrical life rating?

A: No. The TS01CGF specifies 60,000 electrical cycles. Most active substitutes provide 30,000 to 50,000 cycles. The SS series parts provide only 10,000 cycles. Application requirements for cycle life must be evaluated against each substitute specification.

Q: Is contact material compatibility a concern when substituting?

A: The TS01CGF uses silver contact material with gold finish. Substitutes employ copper alloy, phosphor bronze, or gold contact materials. Contact material differences may affect performance in specific circuit environments. Verification with application requirements is recommended when switching contact materials.
