EVQ-PSD02K Equivalent & Substitute Parts

Part Overview

The EVQ-PSD02K is a tactile switch manufactured by Panasonic Electronic Components, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.05A at 12VDC. This component features side actuation, surface mount right-angle mounting, and is designed for applications requiring momentary switching functionality. The product is currently listed as obsolete, making identification of equivalent substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EVQ-PSD02K are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain within acceptable tolerances for substitution:

Critical Matching Parameters:

• Circuit configuration: SPST-NO
• Contact rating: 0.05A @ 12VDC
• Switch function: Off-Mom (Momentary)
• Mounting type: Surface Mount, Right Angle
• Actuator orientation: Side Actuated
• Illumination: Non-Illuminated

Allowable Variation Parameters:

• Operating temperature range: Substitute must meet or exceed the original range
• Operating force: Minor variations acceptable within standard tactile switch tolerances
• Switch travel: Variations within 0.10mm acceptable for equivalent functionality
• Mechanical life: Substitute must meet or exceed original specification
• Outline dimensions: Variations acceptable if PCB footprint compatibility is maintained
• Termination style: Gull Wing acceptable as equivalent to J Lead for surface mount applications

The identified substitute parts (223DM1SAARB and TL3901AGQF180) satisfy all critical matching parameters and represent active product alternatives from established manufacturers.

Parameter Comparison

Engineering Selection Recommendations

Both identified substitute parts represent active product alternatives suitable for replacing the obsolete EVQ-PSD02K in new designs and ongoing production.

223DM1SAARB (CTS Electrocomponents): This substitute maintains electrical equivalence with identical contact rating and circuit configuration. The extended operating temperature range (-40°C ~ 85°C) provides broader environmental capability compared to the original specification. The slightly increased operating force (180gf versus 160gf) and reduced switch travel (0.20mm versus 0.30mm) represent minor mechanical variations within standard tactile switch tolerances. This part carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Mechanical life specification of 50,000 cycles is lower than the original 100,000 cycles.

TL3901AGQF180 (E-Switch): This substitute provides identical electrical specifications and maintains the original switch travel specification of 0.30mm. The extended operating temperature range (-40°C ~ 85°C) exceeds the original capability. Operating force matches the CTS alternative at 180gf. This part also carries ROHS3 compliance and REACH unaffected status. Mechanical life specification of 50,000 cycles matches the CTS alternative. Higher inventory availability (57,340 pieces) compared to the CTS alternative (1,116 pieces) may provide supply chain advantages.

Both substitutes are electrically and mechanically compatible with the EVQ-PSD02K. Selection between them should consider PCB footprint requirements, mechanical life expectations, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 223DM1SAARB or TL3901AGQF180 be used as direct replacements for the EVQ-PSD02K?

A: Both parts satisfy the critical electrical and mechanical compatibility criteria for substitution. The SPST-NO circuit configuration, 0.05A @ 12VDC contact rating, momentary switch function, and side-actuated surface mount right-angle mounting are identical. PCB footprint differences must be evaluated during design integration, as outline dimensions vary (EVQ-PSD02K: 4.60mm x 6.10mm; substitutes: 6.00mm x 5.40mm).

Q: What are the key differences between the two substitute parts?

A: The primary difference is switch travel specification. The TL3901AGQF180 maintains the original 0.30mm travel, while the 223DM1SAARB specifies 0.20mm travel. Both operate at 180gf force compared to the original 160gf. Mechanical life for both substitutes is 50,000 cycles, lower than the original 100,000 cycles. The TL3901AGQF180 offers significantly higher inventory availability.

Q: Are there compliance or regulatory differences between the original part and substitutes?

A: The EVQ-PSD02K product status is listed as obsolete with unspecified RoHS and REACH compliance. Both substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and production.

Q: How do the operating temperature ranges compare?

A: The original EVQ-PSD02K operates from -20°C to 70°C. Both substitute parts extend this range to -40°C to 85°C, providing broader environmental capability suitable for applications requiring extended temperature performance.

Q: What should be considered when selecting between the two substitutes?

A: Evaluate mechanical life requirements (both substitutes specify 50,000 cycles versus the original 100,000 cycles), switch travel preference (TL3901AGQF180 matches original 0.30mm; 223DM1SAARB specifies 0.20mm), PCB layout constraints, and supply chain availability (TL3901AGQF180 has significantly higher stock levels).

Q: Are the termination styles compatible with the original PCB design?

A: The EVQ-PSD02K uses J Lead termination, while both substitutes use Gull Wing termination. Both are surface mount technologies suitable for automated assembly. PCB footprint redesign may be required to accommodate the different termination style and outline dimensions.
