Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVQ-QXM02W is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO to maintain identical electrical behavior
• Contact Rating: Must support 0.02A @ 15VDC minimum
• Mounting Type: Must be Surface Mount for PCB compatibility
• Actuator Height: Must be 2.50mm to ensure mechanical fit within enclosure constraints
• Actuator Orientation: Must be Top Actuated for user interface consistency
• Operating Force: Must be 130gf for tactile feedback consistency
• Switch Travel: Must be 0.25mm for actuation consistency
• Mechanical Life: Must meet or exceed 1,000,000 cycles
• Termination Style: Must be J Lead for solder joint compatibility
• Features: Must include Grounding Pin for circuit design requirements

The EVQ-Q2M02W meets all substitution criteria while offering improved product status (Active) and extended operating temperature range (-40°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

The EVQ-Q2M02W is the direct substitute for the obsolete EVQ-QXM02W. Both components share identical electrical specifications (SPST-NO, 0.02A @ 15VDC) and mechanical characteristics (2.50mm actuator height, 130gf operating force, 0.25mm switch travel, 1,000,000 cycle mechanical life).

The EVQ-Q2M02W offers two advantages over the main part:

• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain continuity
• Extended Operating Temperature Range: The substitute operates from -40°C to 85°C compared to the main part's -20°C to 70°C range, providing broader environmental compatibility
• RoHS3 Compliance: The substitute meets ROHS3 environmental standards

Outline dimensions differ slightly (6.50mm x 6.00mm versus 6.20mm x 6.20mm), requiring verification of PCB layout constraints. Both components use identical J Lead termination and include grounding pins.

Frequently Asked Questions (FAQ)

Q: Can the EVQ-Q2M02W replace the EVQ-QXM02W in existing designs?

A: Yes, provided that PCB layout accommodates the outline dimension difference (6.50mm x 6.00mm versus 6.20mm x 6.20mm). All electrical and mechanical specifications are equivalent.

Q: What is the primary reason for substitution?

A: The EVQ-QXM02W is obsolete. The EVQ-Q2M02W is the active equivalent from the same manufacturer with identical functional specifications.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified in available data. The substitute is supplied in Tape & Reel (TR) packaging, which is standard for surface mount production environments.

Q: Does the extended temperature range of the EVQ-Q2M02W affect compatibility?

A: No. The extended range (-40°C to 85°C versus -20°C to 70°C) is a superset of the original specification and does not impact compatibility. Applications operating within the original temperature range remain fully compatible.

Q: Are both parts RoHS compliant?

A: The EVQ-Q2M02W is ROHS3 compliant. RoHS status for the EVQ-QXM02W is not specified in available documentation.

Q: What is the significance of the grounding pin feature?

A: Both components include a grounding pin, which provides circuit design flexibility for noise reduction and signal integrity in sensitive applications. This feature is maintained in the substitute.
