TL59BF260Q Equivalent & Substitute Parts

Part Overview

The TL59BF260Q 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 12VDC. This through-hole mounted switch features a 260gf operating force and is designed for applications requiring momentary contact actuation. The TL59BF260Q is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL59BF260Q is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPST-NO
• Contact rating must be 0.05A @ 12VDC
• Switch function must be Off-Mom (momentary)
• Mounting type must be Through Hole
• Termination style must be PC Pin
• RoHS3 compliance required

Secondary Compatibility Considerations:

• Actuator height, outline dimensions, and operating force variations are acceptable within mechanical design tolerances
• Switch travel and mechanical life may vary based on application requirements
• Operating temperature range extensions are acceptable for broader environmental compatibility

The substitute parts identified (TL59BF100Q, EVQ-PVA05K, EVQ-PVF05K, EVQ-PVG05K, EVQ-PVW05K) meet all primary criteria. Variations in operating force (100gf to 350gf), actuator height (5.00mm to 9.50mm), and switch travel (0.25mm to 1.30mm) reflect different tactile feedback profiles and mechanical characteristics available within the SPST-NO 0.05A @ 12VDC category.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TL59BF100Q

The TL59BF100Q is the direct E-Switch equivalent within the same TL59 series. It maintains identical mechanical dimensions (9.50mm actuator height, 6.20mm x 6.20mm outline), identical switch travel (0.25mm), and identical mechanical life (100,000 cycles). The primary difference is reduced operating force (100gf versus 260gf), which provides lighter tactile feedback. This part is currently active in production with substantial inventory availability (17,862 pcs), ensuring long-term supply continuity.

Alternative Recommendations: Panasonic EVQ-PV Series

The Panasonic EVQ-PVA05K, EVQ-PVF05K, EVQ-PVG05K, and EVQ-PVW05K switches are cross-manufacturer alternatives that maintain electrical equivalence (SPST-NO, 0.05A @ 12VDC, momentary function). These parts feature reduced actuator height (5.00mm versus 9.50mm) and extended operating temperature range (-30°C ~ 85°C versus -20°C ~ 70°C). Operating force options range from 200gf to 350gf, accommodating different tactile requirements.

Selection Criteria:

• For designs requiring identical mechanical profile and lighter actuation: TL59BF100Q
• For designs tolerating reduced actuator height with extended temperature range: EVQ-PVA05K (220gf), EVQ-PVF05K (250gf closest to original 260gf), or EVQ-PVG05K (200gf)
• For designs requiring maximum operating force: EVQ-PVW05K (350gf), noting reduced mechanical life (30,000 cycles)

All substitute parts maintain ROHS3 compliance and are currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can TL59BF100Q directly replace TL59BF260Q in existing PCB designs?

A: Yes, mechanically and electrically. Both parts share identical through-hole PC pin termination, outline dimensions (6.20mm x 6.20mm), actuator height (9.50mm), and switch travel (0.25mm). The primary difference is operating force (100gf versus 260gf), which affects tactile feedback intensity but not electrical function.

Q: What is the key difference between E-Switch TL59 series and Panasonic EVQ-PV series substitutes?

A: The primary mechanical difference is actuator height: TL59 series maintains 9.50mm height, while EVQ-PV series uses 5.00mm height. This affects PCB clearance requirements and tactile profile. Panasonic parts also offer extended operating temperature range (-30°C ~ 85°C versus -20°C ~ 70°C). Electrical specifications (SPST-NO, 0.05A @ 12VDC) remain identical.

Q: Which substitute part most closely matches the original 260gf operating force?

A: EVQ-PVF05K (250gf) provides the closest operating force match to the original TL59BF260Q (260gf). EVQ-PVW05K offers higher force (350gf) but with reduced mechanical life (30,000 cycles versus 100,000 cycles).

Q: Are all substitute parts available in Cut Tape packaging?

A: Yes. TL59BF100Q is available in Cut Tape (CT) packaging. All Panasonic EVQ-PV alternatives (EVQ-PVA05K, EVQ-PVF05K, EVQ-PVG05K, EVQ-PVW05K) are supplied in Cut Tape packaging.

Q: What is the impact of reduced switch travel in TL59BF100Q (0.25mm) compared to Panasonic alternatives (1.00mm to 1.30mm)?

A: Switch travel defines the distance the actuator moves before electrical contact occurs. Shorter travel (0.25mm) provides faster response and reduced tactile feedback distance. Longer travel (1.00mm to 1.30mm) provides more pronounced tactile feedback and greater mechanical tolerance. Selection depends on application requirements for response speed and user feedback.

Q: Is EVQ-PVW05K suitable for high-cycle applications?

A: EVQ-PVW05K is not recommended for high-cycle applications. It specifies 30,000 mechanical cycles compared to 100,000 cycles for other alternatives. Use EVQ-PVW05K only when maximum operating force (350gf) is required and cycle count remains below 30,000.
