TL1105KF100Q Equivalent & Substitute Parts

Part Overview

The TL1105KF100Q 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 through-hole mounted switch features a top-actuated design with a 100gf operating force and is currently listed as obsolete. Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TL1105KF100Q is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 12VDC)
• Mounting type (Through Hole)
• Actuator height (14.60mm vertical)
• Outline dimensions (6.00mm x 6.00mm)
• Switch travel (0.25mm)
• Operating temperature range (-20°C ~ 70°C)
• Mechanical life (100,000 Cycles)
• Termination style (PC Pin)
• Actuator orientation (Top Actuated)

The TL1105KF160Q is identified as a manufacturer-recommended substitute. While this part maintains identical electrical specifications, mounting characteristics, and mechanical life, it differs in operating force (160gf versus 100gf). This parameter variation must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TL1105KF160Q is the manufacturer-recommended substitute for the obsolete TL1105KF100Q. Both parts maintain identical electrical and mechanical specifications with the exception of operating force. The substitute part is currently in active production status with significantly higher inventory availability (6905 pcs versus 645 pcs), ensuring supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production applications. The transition from obsolete to active product status supports long-term component sourcing reliability.

The primary design consideration is the 60gf increase in operating force (from 100gf to 160gf). This parameter affects tactile feedback and actuation effort. Component selection must account for application-specific requirements regarding user interface feel and mechanical design constraints.

Frequently Asked Questions (FAQ)

Q: Can TL1105KF160Q be used as a direct replacement for TL1105KF100Q?

A: The TL1105KF160Q is electrically and mechanically compatible with identical circuit configuration, contact rating, mounting type, and physical dimensions. The operating force difference (160gf versus 100gf) must be evaluated against application requirements. If the original design specifies 100gf actuation force, the increased force of the substitute may affect user interface performance.

Q: What is the significance of the operating force difference?

A: Operating force determines the mechanical effort required to actuate the switch. The TL1105KF160Q requires 60gf additional force compared to the TL1105KF100Q. Applications sensitive to tactile feedback or requiring minimal actuation effort should account for this parameter variation.

Q: Why is TL1105KF100Q listed as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The TL1105KF160Q, as an active product within the same series, provides continued access to functionally equivalent switching technology.

Q: Are there packaging differences between these parts?

A: The main part (TL1105KF100Q) is specified with dash packaging notation, while the substitute (TL1105KF160Q) is supplied in bulk packaging. Both parts use identical PC Pin termination and through-hole mounting configuration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TL1105KF100Q and TL1105KF160Q are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8536.50.9031) codes.
