TL1105MF100Q Equivalent & Substitute Parts

Part Overview

The TL1105MF100Q 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 substitutes necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL1105MF100Q 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)
• Actuator length (6.85mm)
• Switch travel (0.25mm)
• Mechanical life (100,000 Cycles)
• Operating temperature range (-20°C ~ 70°C)
• Termination style (PC Pin)
• Outline dimensions (7.10mm x 6.55mm)

The TL1105MF160Q qualifies as a substitute based on these parameters. The primary difference is the operating force specification (160gf versus 100gf), which represents a variation within the TL1105 series design envelope and does not affect electrical or mechanical compatibility in applications where the switch function is identical.

Parameter Comparison

Engineering Selection Recommendations

The TL1105MF160Q is the active production substitute for the obsolete TL1105MF100Q. Both parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications (ROHS3 Compliant, REACH Unaffected). The TL1105MF160Q is currently in active production status with significantly higher inventory availability (8207 pcs versus 918 pcs for the original part).

Selection of the TL1105MF160Q is supported by:

• Identical circuit configuration and contact rating
• Identical mounting geometry and actuator dimensions
• Identical switch travel and mechanical life rating
• Equivalent operating temperature range
• Matching RoHS3 and REACH compliance status
• Active production status ensuring long-term availability

Frequently Asked Questions (FAQ)

Q: Can the TL1105MF160Q directly replace the TL1105MF100Q in existing designs?

A: Yes. Both parts share identical electrical ratings, mounting configurations, and mechanical dimensions. The difference in operating force (160gf versus 100gf) reflects a variation within the TL1105 series and does not affect circuit compatibility or PCB layout.

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

A: Operating force specifies the pressure required to actuate the switch. The TL1105MF160Q requires 60gf additional force compared to the TL1105MF100Q. This affects tactile feedback and user interaction but does not alter electrical performance or mechanical compatibility.

Q: Why is the TL1105MF100Q listed as obsolete?

A: Product obsolescence is determined by manufacturer production decisions. The TL1105MF160Q remains in active production and serves as the current equivalent within the TL1105 series.

Q: Are there packaging differences between these parts?

A: The TL1105MF100Q is specified with "-" packaging notation, while the TL1105MF160Q is supplied in Bulk packaging. Both use identical PC Pin termination and are suitable for automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TL1105MF100Q and TL1105MF160Q are ROHS3 Compliant, REACH Unaffected, with Moisture Sensitivity Level 1 (Unlimited), and carry identical ECCN and HTSUS classifications.
