Key Parameters

Substitute Part Grouping Explanation

The D6R50 F1 LFS qualifies as a direct substitute for the D6R80 LFS based on the following critical parameters:

• Circuit Configuration: Both parts are SPST-NO with identical Off-Mom switch function
• Electrical Ratings: Both rated for 100mA DC at 32V
• Mechanical Interface: Both feature through-hole mounting with PC pin termination and round button keyswitch actuators
• Operating Conditions: Identical operating temperature range (-20°C to 85°C) and electrical life (250,000 cycles)
• Compliance: Both are RoHS compliant and REACH unaffected with MSL 1 rating

The primary differences are product status (D6R50 F1 LFS is active versus obsolete) and actuator color (green versus ivory). These differences do not affect functional compatibility in applications where the D6R80 LFS was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The D6R50 F1 LFS is the appropriate substitute for the obsolete D6R80 LFS. The substitute part maintains all critical electrical and mechanical specifications required for functional equivalence. The D6R50 F1 LFS carries active product status with current manufacturing support, ensuring availability for production and field replacement applications. Both parts meet identical compliance requirements including RoHS and REACH standards, with the substitute offering enhanced RoHS3 compliance. The MSL 1 rating on both parts indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the D6R50 F1 LFS be used as a direct replacement for the D6R80 LFS in existing designs?

A: Yes. Both parts share identical electrical ratings (100mA at 32V DC), circuit configuration (SPST-NO), switch function (Off-Mom), and mechanical interface (through-hole PC pin termination). The parts are functionally equivalent for all applications where the D6R80 LFS was originally specified.

Q: What is the difference between the D6R80 LFS and D6R50 F1 LFS?

A: The primary differences are product status and actuator color. The D6R80 LFS is obsolete with an ivory actuator, while the D6R50 F1 LFS is an active product with a green actuator. All electrical, mechanical, and compliance specifications are identical.

Q: Are there packaging differences between these parts?

A: Yes. The D6R80 LFS is supplied in standard packaging, while the D6R50 F1 LFS is supplied in tray packaging. This difference affects handling and storage but does not impact component functionality or performance.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and REACH unaffected. The D6R50 F1 LFS additionally carries ROHS3 compliance certification. Both parts have MSL 1 rating with unlimited moisture sensitivity protection.

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

A: Both the D6R80 LFS and D6R50 F1 LFS are rated for 250,000 electrical cycles, providing equivalent operational longevity in momentary switch applications.
