• Switch function: Off-Mom
• Actuator type: Dual
• Mounting type: Through Hole, Right Angle
• Actuator orientation: Side Actuated
• Operating force: 160gf
• Switch travel: 0.25mm
• Mechanical life: 100,000 Cycles
• Operating temperature range: -20°C ~ 70°C
• Termination style: PC Pin
• Outline dimensions: 8.40mm x 10.50mm

The TL53BF160Q qualifies as a direct substitute, maintaining all critical electrical and mechanical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The TL53BF160Q is the qualified substitute for the obsolete TL53AF160Q. Both components maintain identical electrical specifications, mechanical characteristics, and compliance certifications. The TL53BF160Q offers the advantage of active product status, ensuring continued availability and supply chain support. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The primary difference is the actuator length (3.85mm for TL53AF160Q versus 5.85mm for TL53BF160Q), which may require mechanical design verification in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the TL53BF160Q be used as a direct replacement for the TL53AF160Q?

A: Yes. Both components share identical electrical ratings (0.05A @ 12VDC), circuit configuration (SPST x 2), switch function (Off-Mom), operating force (160gf), and mechanical life (100,000 cycles). The primary design consideration is the actuator length difference: 3.85mm (TL53AF160Q) versus 5.85mm (TL53BF160Q).

Q: What is the significance of the actuator length difference?

A: The actuator length affects the physical reach of the switch button from the PCB surface. The TL53BF160Q has a 2.0mm longer actuator. This difference must be evaluated against available space in the enclosure or mechanical assembly to ensure proper switch accessibility and clearance.

Q: Are there compliance or certification differences between these parts?

A: No. Both the TL53AF160Q and TL53BF160Q are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Both are suitable for applications with equivalent regulatory requirements.

Q: Why is the TL53AF160Q classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The TL53BF160Q remains in active production, providing a viable path for design continuity.

Q: Does packaging differ between these parts?

A: The TL53AF160Q packaging is listed as unspecified, while the TL53BF160Q is supplied in Tray packaging. This affects handling and storage but does not impact electrical or mechanical performance.
