TL59DF160Q Equivalent & Substitute Parts

Part Overview

The TL59DF160Q is an active E-Switch tactile switch designed for through-hole mounting applications requiring low-force actuation. This SPST-NO (Single Pole Single Throw - Normally Open) switch operates at 0.05A @ 12VDC with a 160gf operating force and is suitable for applications demanding reliable momentary contact switching. The part is ROHS3 compliant and carries MSL Level 1 rating, indicating no moisture sensitivity restrictions. Finding equivalent or substitute parts may be necessary due to inventory constraints, packaging format requirements, or specific operating force specifications for particular application needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL59DF160Q is determined by strict adherence to the following critical parameters:

Fixed Parameters (Must Match Exactly):

• Circuit configuration: SPST-NO
• Contact rating: 0.05A @ 12VDC
• Mounting type: Through Hole
• Actuator height (vertical): 13.00mm
• Outline dimensions: 6.20mm x 6.20mm
• Switch travel: 0.25mm
• Mechanical life: 100,000 Cycles
• Operating temperature range: -20°C ~ 70°C
• Termination style: PC Pin
• Actuator orientation: Top Actuated
• Actuator material: Polybutylene Terephthalate (PBT)

Variable Parameter (Allowed Variance):

• Operating force: The TL59DF160Q specifies 160gf. Substitute parts within the TL59 series may feature different operating force ratings (e.g., 260gf) while maintaining all other electrical and mechanical specifications.

The TL59DF260Q qualifies as a substitute based on this framework, differing only in operating force specification while maintaining identical electrical performance, mechanical dimensions, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the TL59DF160Q and TL59DF260Q are active products from E-Switch with identical ROHS3 compliance and MSL Level 1 certification. Selection between these parts depends on application-specific operating force requirements:

• TL59DF160Q is appropriate for applications requiring 160gf actuation force.
• TL59DF260Q is appropriate for applications requiring 260gf actuation force.

Both parts maintain identical electrical ratings (0.05A @ 12VDC), mechanical dimensions (6.20mm x 6.20mm outline, 13.00mm actuator height), and environmental specifications (-20°C ~ 70°C operating range). Packaging format differs between the two parts (Tape & Box for TL59DF160Q versus Cut Tape for TL59DF260Q), which may influence procurement and assembly considerations but does not affect functional compatibility in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can TL59DF260Q replace TL59DF160Q in my circuit?

A: Electrical and mechanical compatibility is maintained. The TL59DF260Q features identical contact rating (0.05A @ 12VDC), circuit configuration (SPST-NO), mounting type (Through Hole), and physical dimensions. The difference is operating force: 260gf versus 160gf. Substitution is valid only if the application can accommodate the higher actuation force requirement.

Q: What is the significance of the operating force difference?

A: Operating force (measured in grams-force) determines the physical pressure required to actuate the switch. The TL59DF160Q requires 160gf of force, while the TL59DF260Q requires 260gf. Applications with tactile feedback requirements or specific user interface specifications must account for this difference.

Q: Are there packaging differences between these parts?

A: Yes. The TL59DF160Q is supplied in Tape & Box (TB) packaging, while the TL59DF260Q is supplied in Cut Tape (CT) packaging. Both formats are standard for through-hole components and do not affect circuit performance. Packaging selection may influence procurement lead times and assembly line compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TL59DF160Q and TL59DF260Q are ROHS3 compliant, carry MSL Level 1 rating (no moisture sensitivity restrictions), and share identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications.

Q: What is the mechanical life expectancy for both parts?

A: Both parts are rated for 100,000 mechanical cycles, indicating equivalent durability and reliability across the specified operating temperature range of -20°C to 70°C.
