EVQ-PC705K Equivalent & Substitute Parts

Part Overview

The EVQ-PC705K is a tactile switch manufactured by Panasonic Electronic Components, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.02A at 15VDC. This component features side actuation, through-hole right-angle mounting, and PC pin termination. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVQ-PC705K is determined by the following critical parameters:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary operation)
• Mounting type must be Through Hole, Right Angle
• Actuator orientation must be Side Actuated
• Termination style must be PC Pin
• Operating temperature range must encompass -20°C ~ 70°C
• Switch travel must be 0.25mm

The substitute parts identified meet these core functional and mechanical requirements. Contact rating differences (0.02A vs. 0.05A) and operating force variations are acceptable within the scope of equivalent substitution, as the substitute parts maintain electrical compatibility with the original circuit topology and mechanical interface.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are manufactured by E-Switch and maintain active product status, ensuring long-term availability and supply chain continuity compared to the obsolete EVQ-PC705K.

TL58XF160Q is the primary substitute candidate. It matches the EVQ-PC705K in actuator length (4.75mm), operates at identical switch travel (0.25mm), and maintains the same through-hole right-angle mounting configuration. The operating force of 160gf differs from the original 260gf but remains within acceptable tactile feedback parameters for standard applications. This part is available in Cut Tape packaging and carries ROHS3 compliance with REACH Unaffected status.

TL1105MF160Q94VO provides an alternative with identical operating force (160gf) to the TL58XF160Q but features a longer actuator length of 6.85mm. This variant is suitable for applications requiring extended actuator reach. Mechanical life rating of 100,000 cycles exceeds the original specification.

LL1105XF065Q offers the lowest operating force (65gf) among the substitutes, making it appropriate for applications requiring minimal actuation pressure. Mechanical life rating of 5,000,000 cycles significantly exceeds all other options. The actuator length of 5.85mm represents a mid-range option between the other substitutes.

All substitute parts comply with current environmental regulations and maintain unlimited moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can TL58XF160Q directly replace EVQ-PC705K in existing PCB designs?

A: Yes, TL58XF160Q is mechanically and electrically compatible. Both parts feature identical actuator length (4.75mm), switch travel (0.25mm), through-hole right-angle mounting, side actuation, and PC pin termination. The contact rating upgrade from 0.02A @ 15VDC to 0.05A @ 12VDC provides enhanced electrical capability without requiring circuit modifications.

Q: What is the significance of the operating force difference between EVQ-PC705K (260gf) and the substitute parts (65-160gf)?

A: Operating force determines the tactile feedback and pressure required to actuate the switch. The EVQ-PC705K requires 260gf, while substitutes range from 65gf to 160gf. Selection depends on the intended user interface experience. Lower operating force (65gf) reduces finger fatigue for frequent actuation; higher force (160gf) provides more deliberate actuation feedback. Verify application requirements before selection.

Q: Are there packaging differences between the substitute parts?

A: TL58XF160Q is supplied in Cut Tape (CT) packaging, matching the original EVQ-PC705K format. TL1105MF160Q94VO and LL1105XF065Q packaging specifications are not detailed in the provided data. Confirm packaging requirements with your procurement process.

Q: How do the mechanical life ratings compare?

A: EVQ-PC705K is rated for 50,000 cycles. TL58XF160Q and TL1105MF160Q94VO are rated for 100,000 cycles. LL1105XF065Q is rated for 5,000,000 cycles. Higher cycle ratings indicate extended operational lifespan and are beneficial for high-frequency switching applications.

Q: What compliance certifications apply to the substitute parts?

A: All substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. MSL ratings of 1 (Unlimited) indicate no moisture sensitivity restrictions during storage and handling.

Q: Can I use LL1105XF065Q if my application requires lower actuation force?

A: Yes, LL1105XF065Q is electrically and mechanically compatible with the EVQ-PC705K circuit topology. The 65gf operating force is suitable for applications where minimal actuation pressure is desired. Verify that the 5.85mm actuator length accommodates your mechanical design constraints.
