Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL3240F100B is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 12VDC)
• Mounting type (Surface Mount)
• Physical outline (6.10mm x 6.10mm)
• Actuator height (7.80mm)
• Actuator orientation (Top Actuated)
• Illumination type and color (LED, Blue)
• Illumination voltage (3.2VDC nominal)
• Operating force (100gf)
• Switch travel (0.20mm)
• Mechanical life (200,000 Cycles)
• Operating temperature range (-25°C to 70°C)
• Termination style (Gull Wing)
• RoHS compliance (ROHS3)

The substitute part TL3240F100BT meets all these criteria and is manufactured by the same supplier within the same product series.

Parameter Comparison

Engineering Selection Recommendations

The TL3240F100BT is the direct substitute for the obsolete TL3240F100B. Both components are manufactured by E-Switch and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and moisture sensitivity level. The TL3240F100BT is currently in active production status, ensuring ongoing availability and supply chain reliability. The TL3240F100BT also features improved moisture sensitivity characteristics (MSL 1 with unlimited shelf life) compared to the TL3240F100B (MSL 2 with 1-year shelf life), providing enhanced storage flexibility and reduced risk of moisture-related degradation.

Both components maintain ROHS3 compliance and identical electrical performance specifications, making the TL3240F100BT a direct functional replacement suitable for new designs and legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can TL3240F100BT be used as a direct replacement for TL3240F100B in existing designs?

A: Yes. The TL3240F100BT is electrically and mechanically equivalent to the TL3240F100B across all functional parameters, including circuit configuration, contact rating, physical dimensions, actuator specifications, and illumination characteristics. No design modifications are required.

Q: What is the significance of the different MSL ratings between these parts?

A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture absorption during storage. The TL3240F100BT has MSL 1 with unlimited shelf life, while the TL3240F100B has MSL 2 with a 1-year shelf life. This means the TL3240F100BT can be stored longer without requiring baking before reflow soldering, reducing inventory management complexity.

Q: Are both parts available in the same packaging format?

A: Yes. Both the TL3240F100B and TL3240F100BT are supplied in Tape & Reel (TR) packaging, ensuring compatibility with automated assembly processes and identical handling requirements.

Q: Why is the TL3240F100B classified as obsolete?

A: The TL3240F100B has been superseded by the TL3240F100BT in the manufacturer's product line. The TL3240F100BT offers improved moisture sensitivity characteristics and active production status while maintaining complete functional equivalence.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components maintain identical RoHS3 compliance status and equivalent regulatory certifications. The ECCN and HTSUS classifications are identical for both parts.
