Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL3240F100R is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 12VDC)
• Surface mount termination style (Gull Wing)
• Physical outline (6.10mm x 6.10mm)
• Actuator height (7.80mm vertical)
• Illumination type and voltage (LED, Red @ 1.8VDC)
• Operating force (100gf)
• Switch travel (0.20mm)
• Mechanical life rating (200,000 Cycles)
• Operating temperature range (-25°C ~ 70°C)
• RoHS3 compliance

Substitute parts must maintain identical electrical performance and mechanical compatibility. Variations in product status, inventory availability, or moisture sensitivity classification do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

TL3240F100RT is the primary substitute for TL3240F100R. This part maintains complete electrical and mechanical equivalence across all critical parameters. The TL3240F100RT carries Active product status, ensuring long-term availability and supply chain stability. The improved moisture sensitivity classification (MSL 1 vs. MSL 2) provides extended shelf life without affecting functional performance in equivalent applications.

TL3240F160R is not a direct substitute. While this part shares identical circuit configuration, mounting type, outline dimensions, and illumination specifications, the operating force specification differs at 160gf compared to the 100gf requirement of TL3240F100R. This parameter variation affects actuator response characteristics and is not interchangeable for applications requiring the specified 100gf actuation force.

Selection should prioritize TL3240F100RT for new designs and procurement activities due to its active status and superior moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can TL3240F160R replace TL3240F100R in existing designs?

A: No. The TL3240F160R operates at 160gf actuating force, whereas the TL3240F100R requires 100gf. This difference affects user interface feel and may cause functional incompatibility in applications with specific actuation force requirements.

Q: What is the primary difference between TL3240F100R and TL3240F100RT?

A: Both parts are electrically and mechanically equivalent. The primary differences are product status (Obsolete vs. Active) and moisture sensitivity level (MSL 2 vs. MSL 1). TL3240F100RT is recommended for new applications due to active availability and extended shelf life capability.

Q: Are all TL3240 series switches pin-compatible?

A: All listed parts share identical surface mount gull wing termination and 6.10mm x 6.10mm outline dimensions, ensuring PCB footprint compatibility. However, operating force variations between part numbers may affect circuit behavior and user interaction characteristics.

Q: What does MSL 2 (1 Year) mean compared to MSL 1 (Unlimited)?

A: Moisture Sensitivity Level (MSL) indicates the maximum shelf life under specified storage conditions. MSL 2 allows one year of storage before component reflow, while MSL 1 permits unlimited storage duration. Both classifications are suitable for standard manufacturing environments.

Q: Are these parts RoHS compliant?

A: Yes. All listed parts carry ROHS3 Compliant certification, meeting current environmental and hazardous substance restrictions.
