D6C80 LFS Equivalent & Substitute Parts

Part Overview

The D6C80 LFS is a pushbutton switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a keyswitch type actuator. This component is rated for 0.1A at 32V DC and features tactile feedback with an ivory-colored square button actuator. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The D6C50 F1 LFS qualifies as a direct substitute for the D6C80 LFS based on the following critical parameters:

• Identical electrical specifications: Both parts maintain 100mA DC current rating and 32V DC voltage rating
• Matching circuit topology: Both are SPST-NO configuration with Off-Mom switch function
• Compatible mechanical interface: Both feature through-hole mounting with PC pin termination and square button actuator type
• Equivalent operational characteristics: Both provide 250,000 cycles electrical life and tactile feedback
• Same environmental compliance: Both operate across -20°C to 85°C temperature range with RoHS and REACH compliance

The primary differences are actuator color (ivory vs. green) and packaging format (bulk vs. tray), neither of which affects functional substitution. The D6C50 F1 LFS carries active product status, ensuring continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The D6C50 F1 LFS is the appropriate substitute for the obsolete D6C80 LFS. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The substitute carries active product status with confirmed inventory availability (9556 units), ensuring reliable procurement for new designs and production support.

The D6C50 F1 LFS meets ROHS3 compliance, representing an updated regulatory classification compared to the original RoHS designation. Both parts maintain REACH unaffected status. The actuator color difference (green vs. ivory) is a cosmetic variation that does not impact electrical function or mechanical compatibility in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can D6C50 F1 LFS directly replace D6C80 LFS in existing designs?

A: Yes. Both parts share identical electrical ratings (100mA, 32V DC), circuit configuration (SPST-NO), switch function (Off-Mom), and mechanical interface (through-hole PC pin termination). No circuit modifications are required.

Q: What is the difference between the two parts?

A: The primary differences are actuator color (ivory on D6C80 LFS vs. green on D6C50 F1 LFS) and packaging format (bulk vs. tray). These differences do not affect electrical performance or mechanical compatibility.

Q: Why is the D6C80 LFS listed as obsolete?

A: The D6C80 LFS has reached end-of-life status. The D6C50 F1 LFS remains in active production and is the recommended alternative for new designs and ongoing production requirements.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant and REACH unaffected. The D6C50 F1 LFS carries ROHS3 classification, representing a current regulatory standard. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the electrical life expectancy for both parts?

A: Both the D6C80 LFS and D6C50 F1 LFS are rated for 250,000 cycles electrical life with tactile feedback operation across the -20°C to 85°C temperature range.

Q: Is packaging format a consideration for substitution?

A: Packaging format (tray vs. bulk) affects logistics and handling but does not impact component function or electrical performance. Select based on production volume and assembly requirements.
