3FTL680 Equivalent & Substitute Parts

Part Overview

The 3FTL680 is a tactile switch manufactured by MEC Switches, part of the Multimec® 3 series. It is a SPST-NO (Single Pole Single Throw - Normally Open) momentary switch with illuminated LED indication in red. The switch is rated for 0.05A at 24VDC and features IP67 ingress protection with sealed construction for flux protection. The 3FTL680 is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

The 3FTH980 qualifies as a direct substitute for the 3FTL680 based on the following critical parameters that determine functional compatibility:

Electrical Parameters: Both parts maintain identical circuit configuration (SPST-NO), switch function (Off-Mom), and contact rating (0.05A @ 24VDC). The illumination specifications are identical: LED red indicator at 2 VDC nominal.

Mechanical Parameters: Both switches share the same actuator type (plunger for cap), mounting method (through hole), actuator height (10.40mm), actuator orientation (top actuated), termination style (PC pin), outline dimensions (10.10mm x 10.10mm), operating force (300gf), switch travel (1.00mm), and mechanical life rating (10,000,000 cycles).

Environmental & Protection: Both parts feature identical ingress protection (IP67), sealed construction with flux protection, and actuator material (PBT).

Regulatory Compliance: Both parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status.

Key Difference: The 3FTH980 is an active product with an extended operating temperature range (-40°C ~ 160°C) compared to the 3FTL680 (-40°C ~ 115°C), and is available in bulk packaging with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The 3FTH980 is the direct substitute for the obsolete 3FTL680. Selection of the 3FTH980 is supported by the following engineering factors:

Product Status: The 3FTH980 is an active product with current manufacturing support, ensuring long-term availability and supply chain continuity. The 3FTL680 is obsolete and subject to inventory depletion.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance status and REACH unaffected designation, ensuring regulatory requirements are met in either configuration.

Functional Equivalence: All electrical, mechanical, and environmental specifications are identical between the two parts. The 3FTH980 provides an extended operating temperature range (-40°C ~ 160°C versus -40°C ~ 115°C), which represents an enhancement rather than a limitation for applications within the original 3FTL680 temperature specification.

Certification & Quality: Both parts carry identical moisture sensitivity level (MSL 1) and mechanical life ratings (10,000,000 cycles), confirming equivalent reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 3FTH980 be used as a direct replacement for the 3FTL680 in existing designs?

A: Yes. The 3FTH980 is electrically and mechanically equivalent to the 3FTL680. All critical parameters including circuit configuration, contact rating, actuator specifications, dimensions, and environmental protection are identical. The 3FTH980 can be substituted without circuit or PCB modifications.

Q: What is the difference between the 3FTL680 and 3FTH980?

A: The primary differences are product status and operating temperature range. The 3FTL680 is obsolete with a -40°C ~ 115°C operating range, while the 3FTH980 is an active product with an extended -40°C ~ 160°C operating range. The 3FTH980 is also available in bulk packaging with higher inventory levels.

Q: Are the packaging specifications different between these parts?

A: Yes. The 3FTL680 is specified with a dash (-) packaging designation, while the 3FTH980 is supplied in bulk packaging. Both parts use identical PC pin termination and through-hole mounting, so packaging differences do not affect functional compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 3FTL680 and 3FTH980 are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1) ratings. They meet equivalent regulatory and environmental standards.

Q: Is the extended temperature range of the 3FTH980 a concern for applications designed for the 3FTL680?

A: No. The extended operating temperature range of the 3FTH980 (-40°C ~ 160°C) encompasses the original 3FTL680 specification (-40°C ~ 115°C). Applications operating within the original temperature range will function identically with either part.

Q: What is the mechanical life expectancy for both switches?

A: Both the 3FTL680 and 3FTH980 are rated for 10,000,000 mechanical cycles, providing equivalent durability and service life.
