TL58WF160Q Equivalent & Substitute Parts

Part Overview

The TL58WF160Q is an E-Switch tactile switch with SPST-NO circuit configuration, rated for 0.05A at 12VDC. This through-hole, right-angle mounted component features a 160gf operating force and is designed for applications requiring reliable momentary switching with a 0.25mm switch travel distance. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design requirements allow for alternative electrical ratings within compatible mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL58WF160Q is determined by 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
• Switch Travel: Must be 0.25mm
• Mechanical Life: Must be 100,000 Cycles minimum
• Operating Temperature Range: Must encompass -20°C ~ 70°C
• Termination Style: Must be PC Pin

The following parameters allow variation within substitute parts:

• Contact Rating: Voltage and current ratings may differ if the application circuit can accommodate the alternative specification
• Actuator Length: Minor variations acceptable if mechanical clearance permits
• Operating Force: Variations acceptable if user actuation requirements are met
• Outline Dimensions: Minor variations acceptable within PCB layout constraints

Two substitute parts meet these criteria: EVQ-PC205K and EVQ-PC405K, both manufactured by Panasonic Electronic Components.

Parameter Comparison

Engineering Selection Recommendations

EVQ-PC205K maintains the 160gf operating force specification matching the TL58WF160Q. Both substitute parts are RoHS compliant and operate within the required temperature range. However, both EVQ-PC205K and EVQ-PC405K are classified as obsolete products, indicating limited future availability. The contact rating differs from the main part (0.02A @ 15VDC versus 0.05A @ 12VDC), requiring circuit-level verification that the application can operate within the lower current specification.

EVQ-PC405K features a reduced 100gf operating force compared to the 160gf specification of the TL58WF160Q. This difference affects user actuation feel and may impact applications with specific tactile feedback requirements.

Both substitute parts have slightly larger outline dimensions (7.50mm x 6.95mm versus 7.40mm x 6.65mm) and longer actuator length (4.75mm versus 3.15mm). PCB layout verification is necessary to confirm mechanical clearance compatibility.

The TL58WF160Q remains the preferred selection due to active product status and higher contact current rating. Substitution should be considered only when primary component availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can EVQ-PC205K and EVQ-PC405K be used interchangeably with TL58WF160Q?

A: Both parts share identical circuit configuration (SPST-NO), switch function (Off-Mom), mounting type (Through Hole, Right Angle), and mechanical life (100,000 cycles). However, they differ in operating force and contact rating. EVQ-PC205K maintains the 160gf operating force, while EVQ-PC405K reduces this to 100gf. Both are rated for 0.02A @ 15VDC compared to the main part's 0.05A @ 12VDC. Circuit-level compatibility must be verified before substitution.

Q: What are the key differences between EVQ-PC205K and EVQ-PC405K?

A: The primary difference is operating force: EVQ-PC205K specifies 160gf (matching TL58WF160Q), while EVQ-PC405K specifies 100gf. All other electrical and mechanical parameters are identical between these two Panasonic parts.

Q: Are there mechanical compatibility concerns with the substitute parts?

A: Yes. Both EVQ-PC205K and EVQ-PC405K have larger outline dimensions (7.50mm x 6.95mm versus 7.40mm x 6.65mm) and longer actuator length (4.75mm versus 3.15mm). PCB layout must be verified to confirm adequate clearance for the longer actuator and slightly larger footprint.

Q: What is the significance of the obsolete product status for the substitute parts?

A: Both Panasonic substitutes are classified as obsolete, indicating they are no longer in active production. This status may result in limited inventory availability and potential supply discontinuation. The TL58WF160Q, being active, offers superior long-term availability.

Q: Can the contact rating difference affect circuit operation?

A: Yes. The substitute parts are rated for 0.02A @ 15VDC, while the main part is rated for 0.05A @ 12VDC. Applications requiring the higher current specification of the TL58WF160Q cannot use these substitutes without circuit redesign. Verify that your application operates within the 0.02A maximum current limit of the substitute parts.

Q: Are there compliance differences between the main part and substitutes?

A: The TL58WF160Q is RoHS3 compliant, while both substitute parts are RoHS compliant. Both meet the required environmental standards. All three parts are rated MSL 1 (Unlimited) and share the same ECCN and HTSUS classifications.
