EVQ-PLBA08 Equivalent & Substitute Parts

Part Overview

The EVQ-PLBA08 is a tactile switch manufactured by Panasonic Electronic Components, designed for surface mount applications with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration. This component operates at 0.02A @ 15VDC and features a 0.80mm actuator height with top actuation. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVQ-PLBA08 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO
• Contact rating: 0.02A @ 15VDC
• Mounting type: Surface Mount
• Actuator orientation: Top Actuated
• Termination style: J Lead
• Switch travel: 0.25mm
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Outline dimensions: ±0.10mm tolerance acceptable for PCB footprint compatibility
• Actuator height: ±0.10mm tolerance acceptable
• Operating force: Variation permitted within mechanical design constraints
• Operating temperature range: Extended range acceptable (substitute may exceed original specification)
• Mechanical life: Equal or greater cycle rating acceptable
• Product status: Active status preferred for long-term availability
• RoHS compliance: ROHS3 acceptable as equivalent or superior to RoHS Compliant

The Würth Elektronik 431183008816 meets all mandatory matching parameters and demonstrates acceptable variation in allowable parameters, qualifying it as a functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 431183008816 is a qualified substitute for the obsolete Panasonic EVQ-PLBA08 based on the following engineering criteria:

Functional Equivalence: All critical electrical and mechanical parameters match or exceed the original specification. The SPST-NO circuit configuration, contact rating, actuator geometry, and switch travel are identical.

Compliance Status: The 431183008816 maintains ROHS3 compliance, which is equivalent to and supersedes the RoHS Compliant status of the original part. Both components carry MSL 1 (Unlimited) moisture sensitivity rating.

Availability Advantage: The substitute part maintains active product status with Würth Elektronik, ensuring long-term supply chain continuity compared to the obsolete EVQ-PLBA08.

Performance Enhancement: The substitute demonstrates superior mechanical life rating (1,000,000 cycles versus 500,000 cycles) and extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C), providing design margin for demanding applications.

Dimensional Compatibility: The 5.00mm x 5.00mm outline of the substitute represents a 0.10mm increase from the original 4.90mm x 4.90mm specification. This variation is within standard PCB footprint tolerance and does not compromise mechanical or electrical function.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 431183008816 be used as a direct replacement for the EVQ-PLBA08 in existing designs?

A: Yes. The substitute meets all mandatory electrical and mechanical parameters. PCB footprints designed for the EVQ-PLBA08 will accommodate the 431183008816 within standard manufacturing tolerances. Verify footprint dimensions with your PCB design tool to confirm clearance for the 5.00mm x 5.00mm outline.

Q: What is the significance of the different operating force ratings (102gf versus 160gf)?

A: Operating force represents the pressure required to actuate the switch. The 431183008816 requires 160gf compared to 102gf for the EVQ-PLBA08. This difference is within acceptable mechanical tolerance for tactile switch applications and does not affect electrical function. User interface feel may be slightly different; evaluate in your specific application context.

Q: Does the extended operating temperature range of the substitute affect compatibility?

A: No. The 431183008816 operates across -40°C ~ 85°C, which encompasses the original -20°C ~ 70°C range. Extended temperature capability provides additional design margin and does not compromise performance within the original specification window.

Q: Are there packaging considerations when switching from Cut Tape to Tape & Reel format?

A: Yes. The EVQ-PLBA08 is supplied in Cut Tape (CT) format, while the 431183008816 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production and offers cost advantages. Verify that your assembly equipment supports TR format or confirm availability of the substitute in alternative packaging if required.

Q: What is the impact of the grounding pin feature on the Würth Elektronik part?

A: The 431183008816 includes a grounding pin feature not present in the EVQ-PLBA08. This feature provides additional electrical stability and is compatible with designs that do not utilize it. If your PCB footprint does not include a grounding pin connection, the substitute will function normally without connection to this feature.

Q: How do the RoHS compliance statuses compare?

A: Both parts are RoHS compliant. The EVQ-PLBA08 carries RoHS Compliant status, while the 431183008816 carries ROHS3 Compliant status. ROHS3 represents the current regulatory standard and is fully compatible with RoHS Compliant requirements. No design changes are necessary from a compliance perspective.
