Substitute Part Grouping Explanation

The EVQ-Q2W03W qualifies as a direct substitute for the EVQ-QXK03W based on the following critical parameters:

Electrical Compatibility: Both parts maintain identical circuit configuration (SPST-NO) and contact rating (0.02A @ 15VDC), ensuring functional equivalence in electrical performance.

Mechanical Compatibility: Both parts share the same actuator height (3.10mm), actuator orientation (top actuated), operating force (260gf), and switch travel (0.25mm), confirming mechanical interchangeability in PCB layouts and user interface applications.

Termination & Mounting: Both parts utilize J Lead termination and surface mount technology, supporting identical assembly processes and soldering procedures.

Environmental Ratings: Both parts carry MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent reliability in standard storage and handling conditions.

Distinguishing Factors: The EVQ-Q2W03W offers extended mechanical life (200,000 cycles versus 100,000 cycles) and an expanded operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C), along with active product status and RoHS3 compliance, making it a superior alternative for new designs.

Parameter Comparison

Engineering Selection Recommendations

The EVQ-Q2W03W is the appropriate substitute for the obsolete EVQ-QXK03W in all applications where the original part was specified.

RoHS3 compliance of the substitute aligns with current regulatory requirements for electronic components in most markets. Both parts carry identical ECCN (EAR99) and HTSUS classifications, confirming equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the EVQ-Q2W03W be used as a direct replacement for the EVQ-QXK03W in existing designs?

A: Yes. Both parts share identical electrical specifications (SPST-NO, 0.02A @ 15VDC), mechanical dimensions (3.10mm actuator height, 260gf operating force, 0.25mm travel), and termination style (J Lead surface mount). PCB layouts and assembly processes require no modification.

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

A: The EVQ-Q2W03W offers extended mechanical life (200,000 cycles versus 100,000 cycles), expanded operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C), active product status, and RoHS3 compliance. The outline dimensions differ slightly (6.50mm x 6.00mm versus 6.20mm x 6.20mm), and packaging format differs (Tape & Reel versus Cut Tape & Digi-Reel).

Q: Are there any packaging considerations when switching from EVQ-QXK03W to EVQ-Q2W03W?

A: The EVQ-QXK03W is supplied in Cut Tape (CT) & Digi-Reel format, while the EVQ-Q2W03W is supplied in Tape & Reel (TR) format. This affects procurement and assembly line handling but does not impact component performance or compatibility.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity classification and identical ECCN (EAR99) and HTSUS codes. The EVQ-Q2W03W additionally carries RoHS3 compliance certification, providing enhanced regulatory alignment for current market requirements.

Q: Is the slight difference in outline dimensions (6.20mm x 6.20mm versus 6.50mm x 6.00mm) a concern for PCB layout?

A: The actuator height remains identical at 3.10mm, and both parts use J Lead termination on surface mount footprints. Verify PCB footprint dimensions against both datasheets to confirm compatibility with your specific layout, particularly if space constraints are critical.
