TLE1105SPF160R1RWHT Equivalent & Substitute Parts

Part Overview

The TLE1105SPF160R1RWHT 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 through-hole mounted switch features a square button actuator with 13.40mm height and white cap, designed for applications requiring momentary contact operation. The product is currently obsolete, making identification of equivalent and substitute parts essential for design continuity and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE1105SPF160R1RWHT is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Contact rating: Minimum 0.05A at operating voltage
• Mounting type: Through Hole
• Outline dimensions: 6.00mm x 6.00mm
• Operating force: 160gf
• Mechanical life: 100,000 cycles minimum
• RoHS3 compliance

Allowable Variations:

• Actuator height (vertical clearance dependent on application)
• Operating voltage rating (must meet or exceed 50VDC requirement)
• Operating temperature range (may differ based on application environment)
• Actuator material composition
• Switch travel distance (within functional tolerance)
• Packaging format

The identified substitutes TLE1105AF160Q and 1825955-6 maintain core electrical and mechanical compatibility while differing in voltage rating, actuator height, and material specifications.

Parameter Comparison

Engineering Selection Recommendations

TLE1105AF160Q (E-Switch, Active Status)

This substitute maintains the same series lineage (TL1105) and identical mechanical specifications including 160gf operating force and 0.25mm switch travel. Both parts share polyamide actuator material and identical outline dimensions. The primary difference is the reduced voltage rating (12VDC versus 50VDC) and lower actuator height (5.00mm versus 13.40mm). Selection of this part is appropriate for applications operating at 12VDC or lower where the reduced actuator height does not create mechanical interference. Active product status ensures ongoing availability and supply chain stability.

1825955-6 (TE Connectivity ALCOSWITCH Switches, Active Status)

This substitute provides SPST-NO momentary operation with identical outline dimensions and 160gf operating force. The contact rating of 0.05A @ 24VDC accommodates mid-range voltage applications. Notable differences include reduced switch travel (0.10mm versus 0.25mm), polybutylene terephthalate actuator material, and extended operating temperature range (-35°C ~ 85°C). The 5.00mm actuator height matches TLE1105AF160Q. This part is suitable for applications requiring higher temperature operation or where the reduced switch travel is functionally acceptable. Active product status provides reliable sourcing.

Both substitutes are ROHS3 compliant and maintain the core SPST-NO momentary switching function required by the original design.

Frequently Asked Questions (FAQ)

Q: Can TLE1105AF160Q be used as a direct replacement for TLE1105SPF160R1RWHT in a 50VDC circuit?

A: No. TLE1105AF160Q is rated for 12VDC maximum. Using it in a 50VDC circuit exceeds the contact rating and creates electrical safety and reliability risks. The voltage rating must match or exceed the circuit operating voltage.

Q: What is the primary difference between the two substitute parts?

A: TLE1105AF160Q operates at 12VDC with 0.25mm switch travel, while 1825955-6 operates at 24VDC with 0.10mm switch travel. Both have 5.00mm actuator height compared to the original 13.40mm. Selection depends on circuit voltage requirements and whether the reduced switch travel is acceptable for the application.

Q: Does the reduced actuator height of the substitutes affect PCB layout compatibility?

A: Yes. The original part has 13.40mm actuator height while both substitutes have 5.00mm height. This difference may affect mechanical clearance, user interface feel, and panel cutout dimensions. PCB layout and mechanical design must be evaluated for compatibility.

Q: Are both substitute parts suitable for high-temperature applications?

A: TLE1105AF160Q operates within -20°C ~ 70°C, matching the original specification. 1825955-6 extends to -35°C ~ 85°C, providing wider temperature range capability. Selection depends on application environment requirements.

Q: What is the significance of the different actuator materials?

A: The original and TLE1105AF160Q use polyamide (PA/Nylon), while 1825955-6 uses polybutylene terephthalate (PBT). Both materials are suitable for tactile switch applications. Material selection may affect durability in specific chemical or thermal environments, but both are ROHS3 compliant.

Q: Can these parts be used interchangeably in the same design?

A: No. Each substitute has distinct voltage ratings, actuator heights, and switch travel specifications. Design selection must be based on specific circuit voltage requirements, mechanical clearance constraints, and operational characteristics needed for the application.
