TL1105VF100R Equivalent & Substitute Parts

Part Overview

The TL1105VF100R 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 50VDC. This component features side actuation, through-hole right-angle mounting, and a polyamide actuator with 100gf operating force. The product is currently obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL1105VF100R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series: TL1105
• Circuit Configuration: SPST-NO
• Switch Function: Off-Mom (Momentary)
• Mounting Type: Through Hole, Right Angle
• Actuator Orientation: Side Actuated
• Actuator Length: 3.85mm
• Outline Dimensions: 7.10mm x 6.55mm
• Operating Force: 100gf
• Switch Travel: 0.25mm
• Mechanical Life: 100,000 Cycles
• Actuator Material: Polyamide (PA), Nylon
• Termination Style: PC Pin
• Operating Temperature Range: -20°C ~ 70°C

Voltage Tolerance Parameter: The contact rating voltage may differ between the main part (50VDC) and substitute parts, provided the substitute operates at equal or lower voltage ratings. A substitute rated at 12VDC is acceptable for applications where the circuit voltage does not exceed 12VDC.

Parameter Comparison

Engineering Selection Recommendations

The TL1105VF100Q serves as a direct substitute for the obsolete TL1105VF100R across all mechanical and functional parameters. Both components are manufactured by E-Switch within the TL1105 series and maintain identical physical dimensions, actuator specifications, and electrical current ratings.

The primary distinction is the contact voltage rating: the TL1105VF100R is rated at 50VDC, while the TL1105VF100Q is rated at 12VDC. Selection between these parts depends on the circuit voltage requirement. For applications operating at 12VDC or lower, the TL1105VF100Q is suitable. For applications requiring 50VDC operation, the TL1105VF100Q is not appropriate.

Both components maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. The TL1105VF100Q is currently in active production with substantial inventory availability, whereas the TL1105VF100R is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the TL1105VF100Q replace the TL1105VF100R in all applications?

A: The TL1105VF100Q is mechanically and functionally equivalent to the TL1105VF100R. However, the voltage rating differs: TL1105VF100Q is rated at 12VDC, while TL1105VF100R is rated at 50VDC. Substitution is valid only for circuits operating at 12VDC or lower.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by matching series designation, circuit configuration (SPST-NO), switch function (Off-Mom), mounting type (Through Hole, Right Angle), actuator orientation (Side Actuated), physical dimensions (7.10mm x 6.55mm), actuator length (3.85mm), operating force (100gf), switch travel (0.25mm), mechanical life (100,000 cycles), and operating temperature range (-20°C ~ 70°C).

Q: Are there packaging differences between these parts?

A: The TL1105VF100R packaging information is not specified in the available data. The TL1105VF100Q is supplied in Bulk packaging. Confirm packaging requirements with the supplier for the obsolete part number if specific packaging is required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TL1105VF100R and TL1105VF100Q are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) rating. Both are classified under ECCN EAR99 and HTSUS 8536.50.9031.

Q: Why is the TL1105VF100R obsolete?

A: Product obsolescence is determined by the manufacturer. The TL1105VF100Q remains in active production and is the recommended source for new designs and production continuity.
