TL1105BF100R Equivalent & Substitute Parts

Part Overview

The TL1105BF100R is an E-Switch tactile switch with SPST-NO circuit configuration, rated for 0.05A at 50VDC. This component features top actuation, through-hole mounting, and a 9.50mm actuator height. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL1105BF100R is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (maintained across all substitutes)
• Contact Rating: 0.05A minimum current capacity (all substitutes meet or exceed this specification)
• Actuator Orientation: Top Actuated (primary substitutes maintain this orientation)
• Mounting Type: Through Hole (all substitutes use through-hole termination)
• Actuator Height: 9.50mm vertical height (maintained in primary substitutes)
• Switch Travel: 0.25mm (consistent across all alternatives)
• Termination Style: PC Pin (maintained across all substitutes)
• Compliance: ROHS3 Compliant (all substitutes meet regulatory requirements)

The substitute parts are grouped into two categories: direct E-Switch alternatives within the TL1105 series and manufacturer-recommended Grayhill Inc. 95C series alternatives. All substitutes maintain the same circuit topology, actuator travel, and termination style. Voltage ratings vary among substitutes (12VDC vs. 50VDC), and operating force specifications differ, requiring application-level verification of compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TL1105VF100Q (E-Switch)

The TL1105VF100Q maintains the same series lineage and is currently in active production status. This part preserves SPST-NO circuit configuration, identical switch travel (0.25mm), matching operating force (100gf), and equivalent temperature range. The primary difference is actuator orientation (side actuated vs. top actuated) and voltage rating (12VDC vs. 50VDC). This substitute is suitable for applications where the lower voltage rating is acceptable and side actuation does not conflict with PCB layout constraints.

Secondary Substitutes: 95C06D2T, 95C06D3T, 95C06D5T, 95C06D6T (Grayhill Inc.)

The Grayhill 95C series provides manufacturer-recommended alternatives with active product status and extended mechanical life ratings. All four variants maintain top actuation orientation, matching the original TL1105BF100R geometry. Key differentiators include:

• 95C06D2T: Identical 100gf operating force; 1,000,000 cycle mechanical life (10x improvement)
• 95C06D3T: 160gf operating force; 1,000,000 cycle mechanical life
• 95C06D5T: 320gf operating force; 300,000 cycle mechanical life
• 95C06D6T: 520gf operating force; 300,000 cycle mechanical life

All Grayhill substitutes operate at 12VDC and feature extended temperature range (-25°C to 70°C). Selection among these variants depends on required operating force and mechanical life specifications for the target application. All substitutes maintain ROHS3 compliance and PC pin termination.

Frequently Asked Questions (FAQ)

Q: Can TL1105VF100Q be used as a direct replacement for TL1105BF100R?

A: TL1105VF100Q shares the same series designation and maintains SPST-NO circuit configuration, identical switch travel, and matching operating force. However, it features side actuation instead of top actuation and operates at 12VDC instead of 50VDC. Substitution is viable only if PCB layout accommodates side actuation and the application voltage requirement does not exceed 12VDC.

Q: What is the primary difference between the Grayhill 95C series substitutes?

A: The 95C series variants differ in operating force specification and mechanical life rating. 95C06D2T matches the original 100gf force with extended 1,000,000 cycle life. 95C06D3T, 95C06D5T, and 95C06D6T provide progressively higher operating forces (160gf, 320gf, and 520gf respectively) for applications requiring increased actuation resistance. Mechanical life varies between 300,000 and 1,000,000 cycles depending on the variant.

Q: Are all substitute parts RoHS compliant?

A: Yes. TL1105VF100Q, 95C06D2T, 95C06D3T, and 95C06D6T are ROHS3 Compliant. 95C06D5T is RoHS Compliant. All substitutes meet regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q: What is the impact of voltage rating differences between substitutes?

A: The original TL1105BF100R is rated for 50VDC, while all substitute parts operate at 12VDC maximum. Substitution is appropriate only for applications where the circuit voltage does not exceed 12VDC. For higher voltage applications, alternative component families must be evaluated.

Q: How do outline dimensions affect PCB layout compatibility?

A: TL1105BF100R has 6.00mm x 6.00mm outline. TL1105VF100Q measures 7.10mm x 6.55mm, and all Grayhill 95C variants measure 6.20mm x 6.20mm. These dimensional variations require verification against PCB footprint specifications and available board space. Actuator height remains consistent at 9.50mm across primary substitutes, supporting mechanical clearance compatibility.

Q: Which substitute offers the best mechanical longevity?

A: 95C06D2T and 95C06D3T both provide 1,000,000 cycle mechanical life, representing a 10-fold improvement over the original TL1105BF100R specification of 100,000 cycles. These variants are recommended for high-cycle applications requiring extended component reliability.
