EVQ-PC505K Equivalent & Substitute Parts

Part Overview

The EVQ-PC505K is a tactile switch manufactured by Panasonic Electronic Components, classified as a light touch switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration. This component features side actuation, through-hole right-angle mounting, and is designed for applications requiring momentary contact switching at low voltage levels (0.02A @ 15VDC). The part is currently listed as obsolete, making identification of compatible substitute components essential for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVQ-PC505K is determined by strict alignment of the following critical parameters:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary contact)
• Mounting type must be through-hole with right-angle orientation
• Actuator must be side-actuated with 4.75mm length
• Switch travel must be 0.25mm
• Mechanical life must meet or exceed 100,000 cycles
• Operating temperature range must encompass -20°C to 70°C
• Termination style must be PC Pin
• Outline dimensions must be compatible with PCB layout constraints

The TL58XF160Q from E-Switch meets all substitution criteria. While the contact rating differs (0.05A @ 12VDC versus 0.02A @ 15VDC), this represents a higher current capacity at a lower voltage, making it suitable for applications within the original part's electrical envelope. The substitute maintains identical mechanical specifications, termination style, and environmental operating range.

Parameter Comparison

Engineering Selection Recommendations

The TL58XF160Q is the qualified substitute for the obsolete EVQ-PC505K. Selection is based on the following engineering factors:

The EVQ-PC505K is no longer in active production status, necessitating component substitution for new designs and production continuity. The TL58XF160Q maintains active product status with E-Switch, ensuring long-term availability and supply chain stability.

Both components are RoHS compliant, with the TL58XF160Q meeting ROHS3 specifications. Both achieve MSL 1 (Unlimited) moisture sensitivity rating, indicating no special handling requirements during storage or assembly.

Mechanical and functional specifications are identical across all critical parameters: SPST-NO circuit, momentary switch function, side-actuated right-angle mounting, 4.75mm actuator length, 0.25mm switch travel, 100,000-cycle mechanical life, and -20°C to 70°C operating temperature range.

The contact rating difference (0.05A @ 12VDC for TL58XF160Q versus 0.02A @ 15VDC for EVQ-PC505K) indicates the substitute has higher current capacity at a lower voltage specification. This relationship is compatible with the original part's electrical requirements for low-voltage, low-current switching applications.

Outline dimensions show minor variation (7.40mm x 6.65mm for TL58XF160Q versus 7.50mm x 6.95mm for EVQ-PC505K), which remains within typical PCB layout tolerances for through-hole component placement.

Frequently Asked Questions (FAQ)

Q: Can the TL58XF160Q directly replace the EVQ-PC505K in existing PCB designs?

A: Yes. Both components share identical mounting type (through-hole right-angle), termination style (PC Pin), and actuator specifications (4.75mm side-actuated length, 0.25mm travel). The minor outline dimension differences (0.1mm and 0.3mm) fall within standard PCB layout tolerances. Pin configuration and electrical function are equivalent.

Q: What is the significance of the different contact ratings?

A: The EVQ-PC505K is rated 0.02A @ 15VDC, while the TL58XF160Q is rated 0.05A @ 12VDC. The substitute has higher current capacity at a lower voltage. For applications using the original part's electrical specifications, the TL58XF160Q provides adequate performance with additional current margin.

Q: Are there compliance or certification differences between these parts?

A: Both components are RoHS compliant. The TL58XF160Q meets ROHS3 specifications, representing a more recent compliance standard. Both achieve MSL 1 (Unlimited) moisture sensitivity rating. The TL58XF160Q includes REACH Unaffected status. These differences represent improvements in regulatory compliance for the substitute.

Q: What is the mechanical life expectancy for both components?

A: Both the EVQ-PC505K and TL58XF160Q are rated for 100,000 mechanical cycles, indicating equivalent durability and expected operational lifespan in momentary switch applications.

Q: Are there packaging differences between the main part and substitute?

A: The EVQ-PC505K is listed with standard packaging notation (-), while the TL58XF160Q is supplied in Cut Tape (CT) packaging. Cut Tape packaging is standard for automated assembly processes and is compatible with standard component handling equipment.

Q: Do both components operate across the same temperature range?

A: Yes. Both the EVQ-PC505K and TL58XF160Q operate across -20°C to 70°C, ensuring equivalent thermal performance in industrial and commercial applications.
