EVQ-PBC05R Equivalent & Substitute Parts

Part Overview

The EVQ-PBC05R is a tactile switch manufactured by Panasonic Electronic Components, classified as SPST-NO (Single Pole Single Throw - Normally Open) with top actuation and through-hole mounting. This component is rated for 0.02A at 15VDC and features a 6.00mm x 6.00mm outline with a 5.00mm actuator height. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVQ-PBC05R is determined by the following critical parameters:

Electrical Compatibility: The substitute must maintain SPST-NO circuit configuration and support the application's voltage and current requirements. The EVQ-PBC05R operates at 0.02A @ 15VDC; substitutes must equal or exceed these ratings.

Mechanical Compatibility: The substitute must feature top actuation, through-hole mounting, and a 6.00mm x 6.00mm outline to ensure PCB footprint compatibility. The 5.00mm actuator height must be maintained for mechanical clearance.

Functional Equivalence: Both the main part and substitute must provide momentary (Off-Mom) switch function with a grounding pin feature.

Reliability Standards: Mechanical life of 100,000 cycles is the baseline requirement. Operating temperature range and RoHS compliance status are secondary considerations based on application environment.

The PTS645TL50-2 LFS meets these substitution criteria through matching circuit configuration, mounting type, outline dimensions, and actuator height, while providing enhanced electrical ratings and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The PTS645TL50-2 LFS is a direct functional substitute for the obsolete EVQ-PBC05R. Both components share identical mechanical footprints, circuit configurations, and mounting characteristics, ensuring PCB compatibility without layout modifications.

The substitute provides superior electrical ratings (0.05A @ 12VDC versus 0.02A @ 15VDC) and an extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C), making it suitable for applications requiring broader environmental tolerance. Both parts maintain equivalent mechanical life specifications and MSL ratings.

The PTS645TL50-2 LFS carries active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory alignment. The substitute is available in bulk packaging with 4479 pieces in stock, supporting production requirements.

Frequently Asked Questions (FAQ)

Q: Can the PTS645TL50-2 LFS be used as a direct replacement for the EVQ-PBC05R without PCB modifications?

A: Yes. Both components feature identical 6.00mm x 6.00mm outlines, 5.00mm actuator heights, and PC pin termination styles. No PCB layout changes are required for mechanical compatibility.

Q: What are the key electrical differences between these parts?

A: The EVQ-PBC05R is rated 0.02A @ 15VDC, while the PTS645TL50-2 LFS is rated 0.05A @ 12VDC. The substitute provides higher current capacity. Applications operating below these ratings are compatible with the substitute.

Q: Does the operating force difference affect functionality?

A: The PTS645TL50-2 LFS has a 130gf operating force compared to the EVQ-PBC05R's 100gf. This represents a 30% increase in actuation force. Applications sensitive to actuation force should evaluate this parameter against user interface requirements.

Q: Are both parts RoHS compliant?

A: Yes. The EVQ-PBC05R is RoHS Compliant, and the PTS645TL50-2 LFS is ROHS3 Compliant. Both meet current regulatory requirements.

Q: What is the availability status of each part?

A: The EVQ-PBC05R is obsolete with 924 pieces in stock. The PTS645TL50-2 LFS is active with 4479 pieces in stock, providing superior long-term availability for production continuity.

Q: Are there any packaging differences?

A: The EVQ-PBC05R is supplied with standard packaging, while the PTS645TL50-2 LFS is supplied in bulk packaging. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.
