TL58WF100Q Equivalent & Substitute Parts

Part Overview

The TL58WF100Q is a tactile switch manufactured by E-Switch, featuring SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration with side actuation and through-hole, right-angle mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity. The switch is rated for 0.05A at 12VDC with an operating force of 100gf and mechanical life of 100,000 cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TL58WF100Q is determined by the following critical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Switch Function: Off-Mom (momentary) operation required
• Mounting Type: Through hole, right-angle configuration
• Actuator Orientation: Side actuation
• Mechanical Compatibility: Switch travel (0.25mm) and mechanical life (100,000 cycles)
• Operating Temperature: -20°C ~ 70°C range
• Electrical Ratings: Contact rating and voltage compatibility
• Compliance: RoHS and REACH status

The substitute parts identified (EVQ-PC205K and EVQ-PC405K) maintain the core SPST-NO circuit topology, side-actuated through-hole right-angle mounting, identical switch travel, and equivalent mechanical life. Both substitutes operate within the specified temperature range and meet RoHS compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both EVQ-PC205K and EVQ-PC405K are functionally equivalent substitutes for the TL58WF100Q based on circuit topology, mounting configuration, and mechanical specifications. Selection between the two Panasonic alternatives depends on application-specific operating force requirements:

EVQ-PC405K is the primary substitute when operating force of 100gf is required, matching the original TL58WF100Q specification exactly.

EVQ-PC205K is suitable for applications where higher operating force (160gf) is acceptable or beneficial for improved tactile feedback and reduced accidental actuation.

Both substitutes are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity level), ensuring compatibility with standard PCB assembly and storage conditions. The increased actuator length (4.75mm versus 3.15mm) must be evaluated for mechanical clearance in the target application. All three parts share identical switch travel (0.25mm), mechanical life (100,000 cycles), and operating temperature range (-20°C ~ 70°C).

Frequently Asked Questions (FAQ)

Q: Can EVQ-PC205K and EVQ-PC405K be used interchangeably with TL58WF100Q?

A: Both Panasonic parts maintain the same SPST-NO circuit topology, side-actuated through-hole right-angle mounting, switch travel, and mechanical life. The primary differences are operating force (160gf for EVQ-PC205K versus 100gf for EVQ-PC405K and TL58WF100Q) and actuator length (4.75mm versus 3.15mm). Interchangeability depends on whether the application can accommodate the increased actuator length and whether the different operating force is acceptable.

Q: What is the impact of the different contact ratings (0.05A @ 12VDC versus 0.02A @ 15VDC)?

A: The TL58WF100Q is rated for higher current (0.05A) at lower voltage (12VDC), while both Panasonic substitutes are rated for lower current (0.02A) at higher voltage (15VDC). Applications must operate within the electrical ratings of the selected substitute. If the circuit requires 0.05A at 12VDC, the Panasonic parts may not be suitable.

Q: Does the 1.6mm difference in actuator length affect PCB design?

A: Yes. The EVQ-PC205K and EVQ-PC405K have actuator lengths of 4.75mm compared to 3.15mm for the TL58WF100Q. Mechanical clearance must be verified in the target enclosure and PCB layout. This difference may require design modifications to accommodate the longer actuator.

Q: Are all three parts RoHS compliant?

A: Yes. The TL58WF100Q is ROHS3 compliant, while both EVQ-PC205K and EVQ-PC405K are RoHS compliant. All three parts meet RoHS requirements and are suitable for applications requiring RoHS compliance.

Q: What is the packaging format for these substitutes?

A: The TL58WF100Q is supplied in standard packaging. Both EVQ-PC205K and EVQ-PC405K are supplied in Cut Tape (CT) format, which is standard for high-volume production and automated assembly processes.
