EVQ-P6UB55 Equivalent & Substitute Parts

Part Overview

The EVQ-P6UB55 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 surface mount component features top actuation, dust proof ingress protection, and a compact 4.10mm x 4.10mm outline suitable for space-constrained applications.

The EVQ-P6UB55 is currently listed as Obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The EVQP6 series provides direct alternatives that maintain functional compatibility while offering improved availability and compliance status.

Substitute Part Grouping Explanation

The EVQ-P6YB55 qualifies as a direct substitute for the EVQ-P6UB55 based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Circuit configuration: SPST-NO
• Contact rating: 0.02A @ 15VDC
• Mounting type: Surface Mount
• Actuator height: 0.58mm
• Outline dimensions: 4.10mm x 4.10mm
• Operating force: 240gf
• Mechanical life: 500,000 Cycles
• Operating temperature range: -20°C ~ 70°C
• Ingress protection: Dust Proof
• Termination style: J Lead
• Moisture sensitivity level: MSL 1 (Unlimited)

Variance:

• Switch travel: 0.20mm (EVQ-P6YB55) vs. 0.25mm (EVQ-P6UB55)

The EVQ-P6YB55 maintains functional equivalence across all critical electrical and mechanical parameters. The minor difference in switch travel (0.20mm vs. 0.25mm) falls within acceptable tolerance for tactile switch applications in this category.

Parameter Comparison

Engineering Selection Recommendations

The EVQ-P6YB55 is the appropriate substitute for the obsolete EVQ-P6UB55 based on the following factors:

Product Status: The EVQ-P6UB55 is classified as Obsolete, while the EVQ-P6YB55 is designated Last Time Buy, providing a defined procurement window for transition planning.

Compliance & Certifications: The EVQ-P6YB55 carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic components in most jurisdictions.

Functional Equivalence: All critical electrical parameters (circuit configuration, contact rating, operating force, mechanical life) and mechanical parameters (mounting type, outline dimensions, actuator height, ingress protection) are identical between the two parts.

Packaging Consideration: The EVQ-P6YB55 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. The EVQ-P6UB55 was supplied in bulk packaging. This packaging difference does not affect component functionality but may require adjustment to procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the EVQ-P6YB55 be used as a direct replacement for the EVQ-P6UB55 in existing designs?

A: Yes. The EVQ-P6YB55 maintains identical electrical ratings (0.02A @ 15VDC), circuit configuration (SPST-NO), mechanical specifications (4.10mm x 4.10mm outline, 0.58mm actuator height), and operating characteristics (240gf operating force, 500,000 cycle mechanical life). The minor difference in switch travel (0.20mm vs. 0.25mm) does not affect functional compatibility for standard tactile switch applications.

Q: What is the significance of the switch travel difference between these parts?

A: Switch travel refers to the distance the actuator moves from rest to full depression. The EVQ-P6YB55 has 0.20mm travel compared to 0.25mm for the EVQ-P6UB55. This 0.05mm difference is within normal manufacturing tolerance for tactile switches and does not impact electrical performance or user interface feel in typical applications.

Q: Why is the EVQ-P6YB55 supplied in Tape & Reel format while the EVQ-P6UB55 was bulk packaged?

A: Tape & Reel (TR) packaging is the industry standard for surface mount components in automated assembly environments. This format improves handling efficiency, reduces component damage during assembly, and is compatible with pick-and-place equipment. Bulk packaging was common for legacy components but has been superseded by standardized tape and reel formats.

Q: Are there any compliance differences between the EVQ-P6UB55 and EVQ-P6YB55?

A: The EVQ-P6YB55 is certified ROHS3 Compliant and REACH Unaffected. The EVQ-P6UB55 compliance status is not specified in available documentation. Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications. The EVQ-P6YB55 meets current regulatory requirements for electronic component distribution in regulated markets.

Q: What is the procurement timeline for the EVQ-P6YB55?

A: The EVQ-P6YB55 is designated Last Time Buy, indicating a defined end-of-life window. Procurement planning should account for this status. Current inventory availability is 23,507 pieces in stock. For long-term production requirements, alternative component families within the EVQP6 series or other tactile switch manufacturers should be evaluated in parallel.
