TL1105RF100Q Equivalent & Substitute Parts

Part Overview

The TL1105RF100Q 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 100gf operating force. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL1105RF100Q is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 12VDC)
• Mounting type (Through Hole, Right Angle)
• Actuator orientation (Side Actuated)
• Outline dimensions (7.10mm x 6.55mm)
• Actuator length (6.15mm)
• Switch travel (0.25mm)
• Mechanical life (100,000 Cycles)
• Operating temperature range (-20°C ~ 70°C)
• Termination style (PC Pin)
• Actuator material (Polyamide/Nylon)

The operating force parameter (100gf) is not a substitution barrier within the TL1105 series, as variants with different force ratings maintain identical electrical and mechanical interfaces. The TL1105RF160Q meets all critical substitution criteria while offering an alternative operating force specification.

Parameter Comparison

Engineering Selection Recommendations

The TL1105RF160Q is the direct substitute for the obsolete TL1105RF100Q. Both components are manufactured by E-Switch within the same TL1105 series and maintain identical electrical specifications, mechanical interfaces, and compliance certifications.

The TL1105RF160Q is currently in active production status, ensuring supply chain availability and long-term support. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

The primary distinction between these components is the operating force specification: 100gf for the TL1105RF100Q versus 160gf for the TL1105RF160Q. This difference affects actuator tactile feedback and activation resistance but does not impact electrical performance, mounting compatibility, or dimensional fit within PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the TL1105RF160Q be used as a direct replacement for the TL1105RF100Q?

A: Yes. The TL1105RF160Q meets all critical substitution criteria including circuit configuration, contact rating, mounting type, actuator orientation, outline dimensions, and termination style. The components are mechanically and electrically compatible.

Q: What is the difference between the 100gf and 160gf operating force ratings?

A: Operating force refers to the pressure required to actuate the switch. The TL1105RF160Q requires 160 grams-force compared to 100 grams-force for the TL1105RF100Q. This affects tactile feedback and activation resistance but does not alter electrical performance or physical fit.

Q: Are there packaging differences between these parts?

A: The TL1105RF100Q was supplied in standard packaging, while the TL1105RF160Q is available in bulk packaging. Both use identical PC Pin termination and are suitable for automated assembly processes.

Q: Do both parts meet current compliance standards?

A: Yes. Both the TL1105RF100Q and TL1105RF160Q are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated industries.

Q: Why is the TL1105RF100Q listed as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions. The TL1105RF160Q remains in active production and serves as the recommended substitute for ongoing designs and production requirements.
