Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 3FTL620 is based on electrical and mechanical parameter equivalence within the Multimec® 3 series. The substitute part must maintain identical specifications across the following critical parameters:

• Circuit configuration: SPST-NO
• Contact rating: 0.05A @ 24VDC
• Actuator type: Plunger for Cap
• Mounting type: Through Hole
• Actuator height: 10.40mm
• Actuator orientation: Top Actuated
• Outline dimensions: 10.10mm x 10.10mm
• Illumination: LED, Green at 2.1 VDC
• Operating force: 300gf
• Ingress protection: IP67
• Switch travel: 1.00mm
• Mechanical life: 10,000,000 Cycles
• Termination style: PC Pin

The 3FTH920 meets all these electrical and mechanical requirements and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 3FTH920 is the direct active substitute for the obsolete 3FTL620. Both parts are ROHS3 compliant and maintain identical electrical and mechanical specifications across all critical parameters. The 3FTH920 offers an extended operating temperature range to 160°C compared to the 3FTL620's 115°C upper limit, providing enhanced thermal performance in demanding applications. The substitute part is available in tube packaging rather than bulk format. Both parts carry identical REACH and ECCN classifications, ensuring regulatory compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 3FTH920 be used as a direct replacement for the 3FTL620 in existing designs?

A: Yes. The 3FTH920 maintains identical electrical ratings, circuit configuration, actuator specifications, and mechanical dimensions. PCB layouts and component footprints require no modification.

Q: What is the difference between the 3FTL620 and 3FTH920?

A: The primary differences are product status and operating temperature range. The 3FTL620 is obsolete with a maximum operating temperature of 115°C. The 3FTH920 is an active product with an extended maximum operating temperature of 160°C. Packaging differs: 3FTL620 is supplied in bulk format, while 3FTH920 is supplied in tube packaging.

Q: Are there any compatibility concerns with the packaging change from bulk to tube?

A: No electrical or mechanical compatibility concerns exist. The packaging change affects only handling, storage, and logistics. Component specifications and performance remain identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 3FTL620 and 3FTH920 are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications.

Q: What is the inventory status of the substitute part?

A: The 3FTH920 has 4,976 pieces in stock as new original inventory, ensuring availability for production and replacement applications.
