D6R50 LFS Equivalent & Substitute Parts

Part Overview

The D6R50 LFS is a pushbutton switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with keyswitch functionality. This through-hole mounted component is rated for 0.1A at 32V DC and features tactile feedback with a green round button actuator. The D6R50 LFS is currently listed as obsolete product status, making identification of suitable substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D6R50 LFS is determined by strict alignment with the following critical parameters:

• Circuit configuration (SPST-NO)
• Switch function (Off-Mom momentary operation)
• Current and voltage ratings (100mA DC, 32V DC)
• Mounting type (Through Hole)
• Keyswitch type classification
• Actuator characteristics (Round, Button, Green color)
• Termination style (PC Pin)
• Operating temperature range (-20°C to 85°C)
• Electrical life rating (250,000 Cycles)
• Tactile feedback feature

The D6R50 F1 LFS qualifies as a direct substitute based on identical alignment across all these parameters. The primary distinction is product status: the substitute part is active and available, whereas the original is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The D6R50 F1 LFS is a direct functional equivalent to the D6R50 LFS. Both components share identical electrical specifications, mechanical characteristics, and operational parameters. The substitute part carries ROHS3 compliance, which represents an enhanced RoHS standard relative to the original RoHS Compliant designation. Both parts maintain REACH Unaffected status and identical moisture sensitivity classification.

The primary advantage of selecting the D6R50 F1 LFS is active product status with confirmed inventory availability (4,777 pieces in stock versus 722 pieces for the obsolete original). This ensures long-term component availability and supply chain continuity for new designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can the D6R50 F1 LFS be used as a direct replacement for the D6R50 LFS in existing designs?

A: Yes. The D6R50 F1 LFS is electrically and mechanically identical to the D6R50 LFS across all specified parameters. No circuit modifications or design changes are required for substitution.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents the third iteration of RoHS compliance standards with updated substance restrictions. Both designations indicate compliance with hazardous substance reduction requirements. The substitute part meets the more current standard.

Q: Are there packaging differences between the main part and substitute?

A: The D6R50 LFS is supplied without specified packaging, while the D6R50 F1 LFS is packaged in trays. This difference does not affect electrical or mechanical compatibility and may provide improved handling and storage benefits.

Q: What parameters must remain identical for substitution eligibility?

A: Circuit configuration (SPST-NO), switch function (Off-Mom), current rating (100mA DC), voltage rating (32V DC), mounting type (Through Hole), keyswitch type, actuator characteristics (Round, Button, Green), termination style (PC Pin), operating temperature range (-20°C to 85°C), and electrical life (250,000 Cycles) must all match exactly.

Q: Is the D6R50 F1 LFS suitable for applications requiring the same electrical performance as the original?

A: Yes. Identical current and voltage ratings, electrical life specifications, and operating temperature ranges ensure equivalent performance in all applications where the D6R50 LFS was originally specified.
