MEC Switches 3FTL6 Equivalent & Substitute Parts

Part Overview

The MEC Switches 3FTL6 is a tactile switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration, rated for 0.05A at 24VDC. This component features top actuation, through-hole mounting, and sealed construction with IP67 ingress protection. The 3FTL6 is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3FTL6 is determined by strict equivalence across the following critical parameters:

Circuit configuration (SPST-NO), contact rating (0.05A @ 24VDC), mounting type (through hole), actuator type (plunger for cap), actuator height (10.40mm), outline dimensions (10.10mm x 10.10mm), operating force (300gf), switch travel (1.00mm), and ingress protection rating (IP67). The substitute part must maintain identical electrical performance, mechanical dimensions, and environmental sealing characteristics to ensure direct compatibility in existing designs.

The 3FTH9 meets all these criteria and is classified as an active product, providing long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

The 3FTH9 is the direct substitute for the obsolete 3FTL6. Both components are manufactured by MEC Switches within the Multimec® 3 series and share identical electrical specifications, mechanical dimensions, and environmental ratings. The 3FTH9 maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

The 3FTH9 offers an extended operating temperature range (-40°C ~ 160°C versus -40°C ~ 115°C), providing additional thermal margin in applications requiring higher temperature tolerance. The 3FTH9 is classified as an active product with substantial inventory availability, ensuring reliable long-term procurement and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can the 3FTH9 be used as a direct replacement for the 3FTL6 in existing designs?

A: Yes. The 3FTH9 is electrically and mechanically equivalent to the 3FTL6 across all critical parameters: circuit configuration, contact rating, mounting type, actuator dimensions, operating force, switch travel, and ingress protection rating. No design modifications are required.

Q: What is the difference between the 3FTL6 and 3FTH9?

A: The primary differences are product status and operating temperature range. The 3FTL6 is obsolete with a -40°C ~ 115°C operating range, while the 3FTH9 is active with a -40°C ~ 160°C operating range. All other electrical and mechanical specifications are identical.

Q: Why is the 3FTL6 listed as obsolete?

A: The 3FTL6 has been discontinued by MEC Switches. The 3FTH9 serves as the active replacement within the Multimec® 3 series.

Q: Are there packaging differences between these parts?

A: The 3FTL6 packaging information is not specified in the available data. The 3FTH9 is supplied in tube packaging. Confirm packaging requirements with your procurement department.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 3FTL6 and 3FTH9 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.50.9031.
