Substitute Part Grouping Explanation

Substitution of the 3FTL6RAS is determined by strict equivalence across the following critical parameters:

  • Circuit configuration: SPST-NO
  • Switch function: Off-Mom (Momentary)
  • Contact rating: 0.05A @ 24VDC
  • Actuator type: Plunger for Cap
  • Mounting type: Through Hole, Right Angle
  • Actuator orientation: Side Actuated
  • Termination style: PC Pin
  • Outline dimensions: 10.10mm x 10.10mm
  • Operating force: 300gf
  • Ingress protection: IP67
  • Sealed construction with flux protection
  • Actuator material: Polybutylene Terephthalate (PBT)
  • Switch travel: 1.00mm
  • Mechanical life: 10,000,000 Cycles

The 3FTH9RAS meets all these criteria and qualifies as a direct substitute. The primary distinction is product status and operating temperature range.

Engineering Selection Recommendations

The 3FTH9RAS is a direct functional equivalent to the 3FTL6RAS. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The 3FTH9RAS carries active product status with significantly higher inventory availability (121,710 pieces versus 821 pieces), ensuring supply chain continuity. The extended operating temperature range of the 3FTH9RAS (-40°C ~ 160°C versus -40°C ~ 115°C) provides additional thermal margin for applications operating at elevated temperatures. All electrical, mechanical, and dimensional specifications remain identical between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the 3FTH9RAS be used as a direct replacement for the 3FTL6RAS in existing designs?

A: Yes. The 3FTH9RAS is electrically and mechanically equivalent to the 3FTL6RAS. All critical parameters including circuit configuration, contact rating, mounting type, dimensions, and operating force are identical. PCB layout and component placement require no modification.

Q: What is the primary difference between these two parts?

A: The 3FTL6RAS is obsolete, while the 3FTH9RAS is an active product. The 3FTH9RAS also features an extended operating temperature range (-40°C ~ 160°C versus -40°C ~ 115°C). Both parts are otherwise functionally identical.

Q: Are there packaging differences between the 3FTL6RAS and 3FTH9RAS?

A: The 3FTL6RAS is supplied in standard packaging, while the 3FTH9RAS is supplied in bulk packaging. This distinction affects procurement and handling but does not impact component performance or compatibility.

Q: Do both parts meet current compliance standards?

A: Yes. Both the 3FTL6RAS and 3FTH9RAS are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

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

A: Both parts are rated for 10,000,000 mechanical cycles, providing equivalent durability and reliability for momentary switch applications.
