TL1105AF160R Equivalent & Substitute Parts

Part Overview

The TL1105AF160R is a tactile switch manufactured by E-Switch, classified as SPST-NO (Single Pole Single Throw - Normally Open) with top actuation and through-hole mounting. This component is rated for 0.05A at 50VDC with an operating force of 160gf and is currently listed as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity, production support, and system maintenance. The TL1105AF160Q serves as the manufacturer-recommended substitute, offering compatible mechanical and electrical characteristics within the TL1105 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL1105AF160R is determined by strict adherence to the following critical parameters:

Mechanical Compatibility:

• Series designation (TL1105)
• Mounting type (Through Hole)
• Outline dimensions (6.00mm x 6.00mm)
• Actuator height off PCB (5.00mm)
• Actuator orientation (Top Actuated)
• Termination style (PC Pin)
• Operating force (160gf)
• Switch travel (0.25mm)

Electrical Compatibility:

• Circuit configuration (SPST-NO)
• Switch function (Off-Mom)
• Contact current rating (0.05A)
• Operating temperature range (-20°C ~ 70°C)
• Mechanical life (100,000 Cycles)

Regulatory Compliance:

• RoHS3 Compliant
• Moisture Sensitivity Level 1

The TL1105AF160Q is classified as a manufacturer-recommended substitute because it maintains identical mechanical dimensions, actuator specifications, circuit configuration, switch function, operating force, and regulatory compliance. The primary difference is the voltage rating (12VDC versus 50VDC), which represents a derating scenario where the substitute part operates at a lower maximum voltage while maintaining all other functional parameters.

Parameter Comparison

Engineering Selection Recommendations

The TL1105AF160Q is the manufacturer-recommended substitute for the obsolete TL1105AF160R. Selection of this substitute is supported by the following engineering criteria:

Product Status: The TL1105AF160Q maintains active product status with 20,621 units in stock, ensuring availability for new designs and production support. The original TL1105AF160R is obsolete with limited inventory (794 units).

Regulatory Compliance: Both parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with current environmental and regulatory requirements.

Mechanical and Electrical Equivalence: The substitute part maintains identical mechanical dimensions, actuator specifications, circuit configuration, and switch function. The contact current rating (0.05A) and mechanical life (100,000 cycles) are preserved.

Voltage Derating Consideration: The TL1105AF160Q operates at 12VDC maximum versus the original 50VDC rating. This represents a voltage derating scenario. Selection of this substitute is appropriate for applications where the circuit voltage does not exceed 12VDC. For applications requiring operation above 12VDC, alternative parts within the TL1105 series with higher voltage ratings must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the TL1105AF160Q be used as a direct replacement for the TL1105AF160R in all applications?

A: The TL1105AF160Q is mechanically and functionally equivalent to the TL1105AF160R. However, the voltage rating differs (12VDC versus 50VDC). Direct substitution is appropriate only for applications where the circuit voltage does not exceed 12VDC. For higher voltage applications, alternative parts must be selected.

Q: What are the critical parameters that define substitution eligibility for the TL1105AF160R?

A: Substitution eligibility is determined by: series designation (TL1105), mounting type (Through Hole), outline dimensions (6.00mm x 6.00mm), actuator height (5.00mm), circuit configuration (SPST-NO), switch function (Off-Mom), contact current rating (0.05A), operating force (160gf), switch travel (0.25mm), mechanical life (100,000 cycles), operating temperature range (-20°C ~ 70°C), and regulatory compliance (ROHS3, MSL 1).

Q: Are there packaging differences between the main part and substitute?

A: The TL1105AF160R is supplied in standard packaging, while the TL1105AF160Q is supplied in bulk packaging. Both parts use identical PC Pin termination and are suitable for automated assembly processes.

Q: What is the significance of the obsolete status of the TL1105AF160R?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this part number. The TL1105AF160Q, with active product status, is the recommended alternative to ensure long-term availability and continued manufacturer support.

Q: Are both parts RoHS compliant?

A: Yes, both the TL1105AF160R and TL1105AF160Q are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and regulatory requirements.
