D6C50 LFS Equivalent & Substitute Parts

Part Overview

The D6C50 LFS is a pushbutton switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a keyswitch design for through-hole mounting. This component is rated for 0.1A at 32V DC and features tactile feedback with a green square button actuator. The D6C50 LFS is currently listed as obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this legacy component is specified.

Substitute Part Grouping Explanation

The D6C50 LFS has one direct substitute within the C&K D6 series: the D6C50 F1 LFS. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Current rating: 100mA DC
• Voltage rating: 32V DC
• Mounting type: Through Hole
• Keyswitch type with square button actuator
• Green actuator color
• PC Pin termination
• Tactile feedback feature
• Operating temperature range: -20°C to 85°C
• Electrical life: 250,000 cycles
• Environmental compliance: RoHS and REACH status

The D6C50 F1 LFS maintains identical electrical and mechanical specifications to the D6C50 LFS, with the primary distinction being active product status and packaging format (Tray versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The D6C50 F1 LFS is the direct substitute for the obsolete D6C50 LFS. Both components are fully equivalent in electrical performance and mechanical form factor. The D6C50 F1 LFS offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts meet RoHS and REACH compliance requirements, with the D6C50 F1 LFS carrying ROHS3 certification. The packaging difference (Tray for the substitute) does not affect functional compatibility. Selection of the D6C50 F1 LFS is appropriate for all applications previously specified with the D6C50 LFS.

Frequently Asked Questions (FAQ)

Q: Are the D6C50 LFS and D6C50 F1 LFS electrically identical?

A: Yes. Both components share identical electrical specifications: SPST-NO circuit configuration, 100mA DC current rating, 32V DC voltage rating, and 250,000 cycle electrical life.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The D6C50 LFS is obsolete, while the D6C50 F1 LFS is active. The D6C50 F1 LFS is supplied in Tray packaging. All electrical and mechanical parameters are identical.

Q: Can the D6C50 F1 LFS be used as a direct replacement in existing designs?

A: Yes. The D6C50 F1 LFS is a direct substitute with no design modifications required. Through-hole mounting, pin configuration, actuator dimensions, and electrical ratings are identical.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS and REACH compliant. The D6C50 F1 LFS carries ROHS3 certification, representing the current RoHS standard. Both maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: Does packaging affect component performance?

A: No. Packaging format (Tray versus standard) does not affect electrical performance or mechanical compatibility. It impacts only logistics and handling procedures.
