TL1105MF250Q Equivalent & Substitute Parts

Part Overview

The TL1105MF250Q is a tactile switch manufactured by E-Switch, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.05A at 12VDC. This component features side actuation, through-hole right-angle mounting, and a 250gf operating force. The product is currently obsolete, making identification of suitable substitute components essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TL1105MF250Q is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO topology must remain unchanged
• Contact Rating: 0.05A @ 12VDC electrical specification must be maintained
• Mounting Type: Through hole, right-angle configuration required for PCB compatibility
• Actuator Orientation: Side actuation must be preserved
• Switch Travel: 0.25mm travel distance must match
• Mechanical Life: 100,000 cycle rating must be met or exceeded
• Operating Temperature Range: -20°C ~ 70°C specification must be supported
• Termination Style: PC pin termination required
• Outline Dimensions: 7.10mm x 6.55mm footprint must be maintained

The TL1105MF160Q qualifies as a direct substitute based on equivalence across all critical parameters. The primary difference is the operating force specification (160gf versus 250gf), which represents a functional variation within the same product family rather than an incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The TL1105MF160Q is the manufacturer-recommended substitute for the obsolete TL1105MF250Q. Both components maintain identical electrical specifications (0.05A @ 12VDC), mechanical footprint (7.10mm x 6.55mm), and mounting configuration (through-hole, right-angle, side-actuated). Both are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

The TL1105MF160Q is currently in active production status with substantial inventory availability (8207 pcs), whereas the TL1105MF250Q is obsolete. The primary functional difference is the operating force: 160gf for the substitute versus 250gf for the original. This difference must be evaluated against application-specific actuation requirements. Both components support identical mechanical life (100,000 cycles) and operating temperature range (-20°C ~ 70°C).

Frequently Asked Questions (FAQ)

Q: Can the TL1105MF160Q be used as a direct replacement for the TL1105MF250Q?

A: The TL1105MF160Q is electrically and mechanically compatible with the TL1105MF250Q across all critical parameters including circuit configuration, contact rating, mounting type, footprint, and termination style. The operating force difference (160gf versus 250gf) must be evaluated for your specific application requirements.

Q: What is the significance of the operating force difference between these two parts?

A: Operating force specifies the pressure required to actuate the switch. The TL1105MF160Q requires 160gf of force, while the TL1105MF250Q requires 250gf. Applications with tactile feedback requirements or specific actuation force specifications must account for this difference.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the TL1105MF250Q and TL1105MF160Q are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the packaging difference between these parts?

A: The TL1105MF250Q is supplied in standard packaging, while the TL1105MF160Q is supplied in bulk packaging. Both maintain identical component specifications and performance characteristics.

Q: Why is the TL1105MF250Q listed as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production. The TL1105MF160Q remains in active production and serves as the current equivalent within the TL1105 series.
