TL3240F260B Equivalent & Substitute Parts

Part Overview

The TL3240F260B 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 illuminated surface mount switch features a top-actuated plunger design with blue LED illumination and is designed for applications requiring momentary switching functionality. The TL3240F260B is currently listed as obsolete, making identification of compatible substitute parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL3240F260B is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPST-NO), switch function (Off-Mom), contact rating (0.05A @ 12VDC), illumination type (LED, Blue), and illumination voltage (3.2 VDC) must remain identical.

Mechanical Parameters: Mounting type (Surface Mount), outline dimensions (6.10mm x 6.10mm), actuator height (7.80mm), actuator orientation (Top Actuated), termination style (Gull Wing), operating force (260gf), and switch travel (0.20mm) must be preserved.

Environmental & Compliance Parameters: Operating temperature range (-25°C ~ 70°C), mechanical life (200,000 Cycles), and RoHS3 compliance must be maintained.

The primary distinction between the main part and its substitute relates to packaging format and product status, not functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TL3240F260BT is the manufacturer-recommended substitute for the obsolete TL3240F260B. Both parts maintain identical electrical and mechanical specifications, ensuring direct functional compatibility in circuit designs and PCB layouts.

The TL3240F260BT offers the advantage of active product status, ensuring continued availability and supply chain reliability. The packaging difference (Tape & Reel versus Cut Tape & Digi-Reel) accommodates different assembly processes without affecting component performance.

The improved Moisture Sensitivity Level (MSL 1 with unlimited shelf life versus MSL 2 with 1-year shelf life) on the TL3240F260BT provides enhanced storage stability and reduced risk of moisture-related failures during extended warehousing.

Both parts maintain ROHS3 compliance and identical environmental operating parameters, supporting applications across the specified temperature range of -25°C to 70°C.

Frequently Asked Questions (FAQ)

Q: Can the TL3240F260BT be used as a direct replacement for the TL3240F260B?

A: Yes. The TL3240F260BT is electrically and mechanically identical to the TL3240F260B. All functional parameters, including circuit configuration, contact rating, mechanical life, and operating specifications, are equivalent. The parts are interchangeable at the circuit and PCB layout level.

Q: What is the difference between Cut Tape (CT) & Digi-Reel and Tape & Reel (TR) packaging?

A: Cut Tape packaging is supplied in smaller quantities on individual tape segments, suitable for manual assembly or low-volume production. Tape & Reel packaging provides components on continuous reels, optimized for automated pick-and-place assembly equipment. Both packaging formats contain identical components with no functional differences.

Q: Why is the TL3240F260B listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions based on market demand and product lifecycle management. The TL3240F260BT remains in active production as the current equivalent offering from E-Switch.

Q: Does the improved Moisture Sensitivity Level (MSL) on the TL3240F260BT affect compatibility?

A: No. The MSL rating affects storage and handling requirements, not electrical or mechanical performance. The improved MSL 1 rating on the TL3240F260BT provides extended shelf life (unlimited versus 1 year) and reduces moisture absorption risk, but does not impact functional compatibility or circuit operation.

Q: Are there any design considerations when transitioning from TL3240F260B to TL3240F260BT?

A: No design changes are required. Identical outline dimensions (6.10mm x 6.10mm), actuator height (7.80mm), termination style (Gull Wing), and all electrical specifications ensure drop-in compatibility. Existing PCB layouts, schematics, and assembly processes require no modification.
