Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVQ-PQHB55 is determined by strict alignment of the following critical parameters:

• Circuit Configuration: Must be SPST-NO to maintain identical electrical switching behavior
• Contact Rating: Substitute must support minimum 0.02A @ 15VDC; higher ratings are acceptable as they provide design margin
• Mounting Type: Surface mount requirement is mandatory for PCB compatibility
• Actuator Type & Orientation: Snap dome, top actuated configuration ensures mechanical and functional equivalence
• Actuator Height & Travel: 0.55mm height and 0.20mm travel must be maintained for mechanical fit and tactile response
• Outline Dimensions: 4.50mm x 4.50mm footprint is required for PCB layout compatibility
• Operating Force: 160gf operating force ensures consistent user interface behavior
• Operating Temperature Range: Minimum -20°C ~ 70°C coverage required
• Moisture Sensitivity Level: MSL 1 (Unlimited) is acceptable

The TL3315NF160Q from E-Switch meets all substitution criteria and is classified as an equivalent part.

Engineering Selection Recommendations

The TL3315NF160Q is a direct functional equivalent to the EVQ-PQHB55 and is recommended as the primary substitute component. Key advantages of this substitution include:

• Product Status: The TL3315NF160Q is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete EVQ-PQHB55
• Enhanced Electrical Performance: Contact rating of 0.05A @ 15VDC exceeds the original 0.02A requirement, providing additional design margin
• Improved Mechanical Durability: Mechanical life specification of 500,000 cycles surpasses the original 200,000 cycles, extending component service life
• Compliance Certifications: TL3315NF160Q is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements
• Identical Mechanical Interface: All critical mechanical parameters including actuator height, travel distance, operating force, and footprint dimensions are identical, ensuring direct PCB compatibility without layout modifications

The substitute part requires no design changes and can be implemented as a direct replacement in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the TL3315NF160Q be used as a direct replacement for the EVQ-PQHB55 without PCB modifications?

A: Yes. The TL3315NF160Q is mechanically and electrically compatible with the EVQ-PQHB55. All critical parameters including footprint dimensions (4.50mm x 4.50mm), actuator height (0.55mm), operating force (160gf), and switch travel (0.20mm) are identical. No PCB layout changes are required.

Q: What is the difference in contact rating between these two parts?

A: The EVQ-PQHB55 is rated for 0.02A @ 15VDC, while the TL3315NF160Q is rated for 0.05A @ 15VDC. The substitute part has a higher contact rating, which provides additional electrical design margin and is fully compatible with applications designed for the lower rating.

Q: Are there packaging differences between these components?

A: Yes. The EVQ-PQHB55 is supplied in Tape & Reel (TR) packaging, while the TL3315NF160Q is available in Cut Tape (CT) and Digi-Reel® packaging. Both packaging formats are standard for surface mount components and do not affect component functionality or PCB assembly compatibility.

Q: What is the significance of the mechanical life difference?

A: The EVQ-PQHB55 specifies 200,000 mechanical cycles, while the TL3315NF160Q specifies 500,000 mechanical cycles. The substitute part offers extended operational life, which is beneficial for applications requiring high cycle counts or extended service intervals.

Q: Why is the EVQ-PQHB55 listed as obsolete?

A: The EVQ-PQHB55 is no longer in active production by Panasonic Electronic Components. The TL3315NF160Q from E-Switch is an active product that fulfills the same functional requirements and is recommended for new designs and ongoing production support.

Q: Are there any compliance or certification differences?

A: The TL3315NF160Q carries RoHS3 Compliance and REACH Unaffected certifications, meeting current environmental and regulatory standards. These certifications ensure compliance with modern manufacturing and disposal requirements.
