Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSL0V511LFT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (Momentary)
• Contact rating: 0.05A @ 32VDC
• Mounting type: Through Hole, Right Angle
• Actuator orientation: Side Actuated
• Outline dimensions: 8.00mm x 8.00mm
• Actuator length (right angle): 8.53mm
• Operating force: 500gf
• Ingress protection: IP60 - Dust Tight
• Termination style: PC Pin
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The substitute part KSL0V511 LFTR meets all mandatory matching parameters and is manufactured by the same supplier (C&K) within the same product series (KSL). This part maintains functional and mechanical compatibility with the discontinued KSL0V511LFT.

Parameter Comparison

Engineering Selection Recommendations

The KSL0V511 LFTR is a direct functional equivalent to the discontinued KSL0V511LFT. Both parts are manufactured by C&K within the KSL series and share identical electrical and mechanical specifications across all critical parameters.

The substitute part offers the following advantages:

• Active product status with confirmed inventory availability (10,033 pcs in stock)
• Identical circuit configuration, contact rating, and mounting specifications
• Identical RoHS3 compliance and REACH unaffected status
• Documented mechanical life specification (100,000 cycles) and switch travel (0.70mm)

The operating temperature range of the substitute part (-40°C to 85°C) is narrower than the main part (-40°C to 90°C) by 5°C at the upper limit. This difference is applicable only in applications requiring operation above 85°C.

For applications operating within the -40°C to 85°C range, the KSL0V511 LFTR provides full functional and mechanical compatibility with identical electrical performance and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can KSL0V511 LFTR be used as a direct replacement for KSL0V511LFT?

A: Yes, for applications operating within -40°C to 85°C. Both parts share identical circuit configuration (SPST-NO), contact rating (0.05A @ 32VDC), mounting type (through-hole right angle), outline dimensions (8.00mm x 8.00mm), and all other critical electrical and mechanical parameters. The substitute part is currently in active production.

Q: What is the difference in operating temperature range?

A: The KSL0V511LFT operates from -40°C to 90°C, while the KSL0V511 LFTR operates from -40°C to 85°C. The substitute part has a 5°C lower maximum operating temperature. If your application requires operation above 85°C, the original part specification must be maintained.

Q: Are there packaging differences between these parts?

A: The KSL0V511LFT packaging is listed as "-" (not specified), while the KSL0V511 LFTR is supplied in Bulk packaging. Both parts use identical PC Pin termination and are suitable for through-hole PCB assembly.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the KSL0V511LFT and KSL0V511 LFTR are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited) and ingress protection rating (IP60 - Dust Tight).

Q: What mechanical life specification applies to the substitute part?

A: The KSL0V511 LFTR is rated for 100,000 mechanical cycles. The original KSL0V511LFT does not specify a mechanical life value in the available documentation.
