TL58VF160Q Equivalent & Substitute Parts

Part Overview

The TL58VF160Q is a tactile switch manufactured by E-Switch, classified as SPST-NO (Single Pole Single Throw - Normally Open) with side actuation and through-hole, right-angle mounting. This component is rated for 0.05A at 12VDC and features a 160gf operating force with 0.25mm switch travel. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL58VF160Q is determined by strict alignment of the following critical parameters:

• Circuit Configuration: Must be SPST-NO
• Switch Function: Must be Off-Mom (Momentary)
• Mounting Type: Must be Through Hole, Right Angle
• Actuator Orientation: Must be Side Actuated
• Operating Force: Must be 160gf
• Switch Travel: Must be 0.25mm
• Termination Style: Must be PC Pin
• Mechanical Life: Must be 100,000 Cycles
• Operating Temperature Range: Must support -20°C ~ 70°C

The EVQ-PC205K from Panasonic Electronic Components meets all substitution criteria. While the contact rating differs (0.02A @ 15VDC versus 0.05A @ 12VDC), this represents a higher voltage and lower current specification, which is acceptable for applications within the original part's electrical envelope. The actuator length differs (4.75mm versus 3.85mm), requiring verification of mechanical clearance in the target application.

Parameter Comparison

Engineering Selection Recommendations

The EVQ-PC205K is the manufacturer-recommended substitute for the TL58VF160Q. Both components are obsolete, requiring sourcing from inventory stock. The EVQ-PC205K carries RoHS Compliance certification, while the original part is ROHS3 Compliant; both meet modern environmental and regulatory standards.

Selection of the EVQ-PC205K requires confirmation that:

1. The increased actuator length (4.75mm versus 3.85mm) does not create mechanical interference within the target PCB assembly
2. The application's electrical load does not exceed 0.02A at 15VDC, which represents the substitute part's contact rating
3. PCB layout accommodates the slightly larger outline dimensions (7.50mm x 6.95mm versus 7.40mm x 6.65mm)

Both components share identical mechanical life (100,000 cycles), operating force (160gf), switch travel (0.25mm), and temperature operating range, ensuring functional equivalence for momentary switching applications.

Frequently Asked Questions (FAQ)

Q: Can the EVQ-PC205K directly replace the TL58VF160Q without PCB modification?

A: Direct replacement is possible if PCB layout accommodates the larger actuator length (4.75mm) and outline dimensions. Physical clearance verification is required before substitution.

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

A: The EVQ-PC205K has a lower current rating but higher voltage rating. Applications must operate within 0.02A maximum current and 15VDC maximum voltage. If the original application requires 0.05A at 12VDC, the substitute may not be suitable.

Q: Are both parts RoHS compliant?

A: Yes. The TL58VF160Q is ROHS3 Compliant, and the EVQ-PC205K is RoHS Compliant. Both meet environmental regulatory requirements.

Q: What is the packaging format for the EVQ-PC205K?

A: The EVQ-PC205K is supplied in Cut Tape (CT) packaging format.

Q: Do both parts have the same mechanical life expectancy?

A: Yes. Both the TL58VF160Q and EVQ-PC205K are rated for 100,000 mechanical cycles, ensuring equivalent durability for momentary switching applications.

Q: What is the moisture sensitivity level for both parts?

A: Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
