TL1105F160R Equivalent & Substitute Parts

Part Overview

The TL1105F160R 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 compatible substitute parts is essential for ongoing design support, maintenance, and production continuity. The TL1105 series provides direct alternatives that maintain functional equivalence while offering improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL1105F160R is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must remain SPST-NO
• Switch Function: Must remain Off-Mom (momentary operation)
• Operating Force: Must match 160gf
• Mounting Type: Must remain Through Hole
• Actuator Height: Must match 4.30mm vertical dimension
• Outline Dimensions: Must match 6.00mm x 6.00mm footprint
• Termination Style: Must remain PC Pin
• Switch Travel: Must match 0.25mm
• Mechanical Life: Must match 100,000 cycles minimum
• Operating Temperature Range: Must match -20°C ~ 70°C
• RoHS Compliance: Must maintain ROHS3 Compliant status

The TL1105F160Q qualifies as a direct substitute based on full alignment with these parameters. The voltage rating difference (50VDC vs. 12VDC) does not disqualify substitution, as the lower voltage rating of the substitute part remains compatible with applications designed for the original 50VDC specification.

Parameter Comparison

Engineering Selection Recommendations

The TL1105F160Q is the qualified substitute for the obsolete TL1105F160R. Selection is based on the following engineering criteria:

Product Status: The TL1105F160Q maintains active product status with current manufacturing support, whereas the TL1105F160R is obsolete. This transition ensures long-term supply chain continuity and access to technical support.

Compliance Certifications: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity ratings. No compliance degradation occurs with substitution.

Functional Equivalence: All mechanical, electrical, and operational parameters remain identical, including circuit configuration, switch function, operating force, mechanical life, and temperature range. The parts are pin-compatible and footprint-compatible.

Voltage Rating Consideration: The substitute part is rated for 12VDC versus the original 50VDC. In applications operating at or below 12VDC, the substitute provides equivalent performance. In applications requiring operation above 12VDC, the original specification must be verified before substitution.

Frequently Asked Questions (FAQ)

Q: Can TL1105F160Q replace TL1105F160R in all applications?

A: TL1105F160Q is mechanically and functionally equivalent to TL1105F160R across all parameters except voltage rating. Substitution is valid for applications operating at 12VDC or below. Applications requiring operation above 12VDC require verification of the substitute part's voltage capability against circuit requirements.

Q: What is the difference between the two part numbers?

A: The primary difference is the contact voltage rating: TL1105F160R is rated for 50VDC, while TL1105F160Q is rated for 12VDC. All other specifications—circuit configuration, operating force, mechanical life, dimensions, and temperature range—are identical.

Q: Are the parts physically interchangeable?

A: Yes. Both parts share identical outline dimensions (6.00mm x 6.00mm), actuator height (4.30mm), termination style (PC Pin), and mounting type (Through Hole). They are direct drop-in replacements from a PCB layout perspective.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by the manufacturer. The TL1105F160Q remains in active production and serves as the current equivalent within the TL1105 series.

Q: What packaging is available for the substitute part?

A: TL1105F160Q is available in Bulk packaging, with 1790 pieces currently in stock.

Q: Are there any compliance concerns with substitution?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 ratings. Substitution does not introduce compliance risks.
