EVQ-QXT02W Equivalent & Substitute Parts

Part Overview

The EVQ-QXT02W 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 with a 2.50mm actuator height and is designed for applications requiring momentary switching functionality.

The EVQ-QXT02W is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVQ-QXT02W is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Switch function (Off-Mom momentary operation)
• Contact rating (0.02A @ 15VDC minimum)
• Mounting type (Surface Mount)
• Actuator height (2.50mm)
• Actuator orientation (Top Actuated)
• Termination style (J Lead)
• Operating force (260gf)
• Switch travel (0.25mm)

The EVQ-Q2U02W meets all substitution criteria. While this part exhibits enhanced mechanical life (200,000 cycles versus 100,000 cycles) and an extended operating temperature range (-40°C to 85°C versus -20°C to 70°C), these represent improvements that do not compromise compatibility. The outline dimensions differ slightly (6.50mm x 6.00mm versus 6.20mm x 6.20mm), requiring PCB layout verification for space-constrained applications.

Parameter Comparison

Engineering Selection Recommendations

The EVQ-Q2U02W is the qualified substitute for the obsolete EVQ-QXT02W. Selection of this substitute is supported by the following factors:

• Functional equivalence across all critical electrical and mechanical parameters
• Active product status with confirmed supply availability
• ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Enhanced mechanical life rating (200,000 cycles) provides extended operational reliability
• Extended operating temperature range (-40°C to 85°C) accommodates broader environmental conditions
• Identical contact rating, actuator specifications, and termination style ensure direct functional replacement

PCB layout verification is required to accommodate the outline dimension variance (6.50mm x 6.00mm versus 6.20mm x 6.20mm). In space-constrained designs, this dimensional difference may necessitate minor layout adjustments.

Frequently Asked Questions (FAQ)

Q: Can the EVQ-Q2U02W be used as a direct replacement for the EVQ-QXT02W?

A: Yes. The EVQ-Q2U02W meets all functional and electrical requirements for substitution. Both parts share identical circuit configuration, contact rating, actuator specifications, and termination style. PCB layout verification is required due to outline dimension differences.

Q: What are the key differences between these parts?

A: The primary differences are outline dimensions (6.50mm x 6.00mm versus 6.20mm x 6.20mm), mechanical life rating (200,000 cycles versus 100,000 cycles), and operating temperature range (-40°C to 85°C versus -20°C to 70°C). The EVQ-Q2U02W offers enhanced performance specifications.

Q: Is the EVQ-Q2U02W available in the same packaging as the EVQ-QXT02W?

A: The EVQ-Q2U02W is supplied in Tape & Reel (TR) packaging. Packaging format compatibility should be verified against assembly process requirements.

Q: Are there compliance differences between these parts?

A: The EVQ-Q2U02W carries ROHS3 compliance and REACH unaffected status. Compliance documentation for the obsolete EVQ-QXT02W was not provided. Current regulatory requirements favor the EVQ-Q2U02W.

Q: Will the outline dimension difference affect PCB assembly?

A: The outline dimension variance requires PCB layout verification. In designs with tight component spacing, minor layout adjustments may be necessary. Footprint compatibility should be confirmed before implementation.
