TL53DF160Q Equivalent & Substitute Parts

Part Overview

The TL53DF160Q is a tactile switch manufactured by E-Switch, configured as SPST x 2 (Single Pole Single Throw, dual switch) with side actuation and through-hole, right-angle mounting. This component is rated for 0.05A at 12VDC and features an operating force of 160gf with a mechanical life of 100,000 cycles. The TL53DF160Q is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

The TL53EF160Q qualifies as a direct substitute for the TL53DF160Q based on the following critical parameters:

• Circuit Configuration: Both parts maintain SPST x 2 dual-switch architecture
• Contact Rating: Identical electrical specification of 0.05A @ 12VDC
• Switch Function: Both operate as Off-Mom (momentary) switches
• Actuator Type & Orientation: Dual side-actuated configuration preserved
• Mounting Type: Through-hole, right-angle mounting maintained
• Operating Force: 160gf specification identical
• Switch Travel: 0.25mm travel distance consistent
• Mechanical Life: 100,000 cycles specification matched
• Operating Temperature Range: -20°C ~ 70°C range identical
• Compliance: Both ROHS3 compliant with MSL 1 rating

The primary difference is the actuator length (6.85mm vs. 7.35mm) and product status transition from obsolete to active, with improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The TL53EF160Q is the direct equivalent for the obsolete TL53DF160Q. Selection of the TL53EF160Q is supported by:

• Product Status: The substitute transitions from obsolete to active status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements
• Electrical & Mechanical Specifications: All critical functional parameters remain unchanged, including contact rating, circuit configuration, operating force, and mechanical life
• Physical Compatibility: The outline dimensions (8.40mm x 10.50mm) are identical; the actuator length difference (0.5mm) must be evaluated within the specific application's mechanical constraints

Frequently Asked Questions (FAQ)

Q: Can TL53EF160Q directly replace TL53DF160Q in existing designs?

A: Yes, the TL53EF160Q maintains identical electrical specifications (0.05A @ 12VDC), circuit configuration (SPST x 2), operating force (160gf), and mechanical life (100,000 cycles). The 0.5mm difference in actuator length (6.85mm vs. 7.35mm) must be evaluated for mechanical clearance in your specific PCB assembly.

Q: What is the primary reason for substitution?

A: The TL53DF160Q is classified as obsolete. The TL53EF160Q is the active equivalent from the same manufacturer and series, providing assured supply availability and continued manufacturing support.

Q: Are compliance certifications maintained?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited) rating and REACH unaffected status. No compliance changes occur with substitution.

Q: What is the difference in packaging?

A: The TL53DF160Q is supplied without specified packaging, while the TL53EF160Q is supplied in Tray packaging. This does not affect component functionality or electrical performance.

Q: Are there inventory considerations?

A: The TL53EF160Q has significantly higher inventory availability (2774 Pcs) compared to the obsolete TL53DF160Q (828 Pcs), supporting procurement reliability for new production runs.
