Substitute Part Grouping Explanation

The D6L90 F1 LFS qualifies as a direct substitute based on the following criteria:

Electrical Compatibility: Both parts maintain identical circuit configuration (SPST-NO), current rating (100mA DC), and voltage rating (32V DC), ensuring functional equivalence in switching applications.

Mechanical Compatibility: Both parts share the same actuator type (plunger for cap), mounting method (through hole), and termination style (PC pin), confirming physical interchangeability in existing designs.

Environmental & Compliance Alignment: Both parts operate within the same temperature range (-20°C to 85°C), maintain identical electrical life (250,000 cycles), and meet equivalent RoHS and REACH compliance standards.

Key Differentiator: The D6L90 F1 LFS is the active production variant of the D6L90 series, with identical electrical and mechanical specifications but enhanced availability and current manufacturing status.

Engineering Selection Recommendations

The D6L90 F1 LFS is the recommended active equivalent for the obsolete D6L90. Selection is based on:

Product Status: The D6L90 F1 LFS maintains active production status with substantial inventory availability (266,433 pcs), ensuring long-term supply chain reliability compared to the obsolete D6L90.

Compliance Certification: The D6L90 F1 LFS meets ROHS3 compliance, representing current regulatory standards. Both parts maintain REACH Unaffected status and equivalent environmental classifications.

Functional Equivalence: Electrical and mechanical parameters are identical across both parts, confirming direct substitution without design modification. The switch function (Off-Mom), circuit topology (SPST-NO), and performance characteristics remain unchanged.

Packaging Consideration: The D6L90 F1 LFS is supplied in tray packaging, which may differ from original bulk packaging. Procurement and assembly processes should account for this packaging format change.

Frequently Asked Questions (FAQ)

Q: Can the D6L90 F1 LFS be used as a direct replacement for the D6L90?

A: Yes. Both parts are electrically and mechanically identical. The D6L90 F1 LFS is the active production variant with identical SPST-NO circuit configuration, 100mA/32V ratings, plunger actuator, through-hole mounting, and PC pin termination. No design changes are required.

Q: What is the primary reason for substitution?

A: The D6L90 is obsolete. The D6L90 F1 LFS is the active equivalent with current manufacturing support and reliable supply availability.

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

A: Both parts are RoHS compliant and REACH Unaffected. The D6L90 F1 LFS meets ROHS3 standards, representing current regulatory requirements. This upgrade does not affect functional performance.

Q: Does packaging format affect compatibility?

A: Packaging format (bulk vs. tray) does not affect electrical or mechanical compatibility. The D6L90 F1 LFS is supplied in tray packaging. Assembly and procurement workflows may require adjustment to accommodate this packaging change, but component performance remains identical.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate within -20°C to 85°C and maintain 250,000 electrical life cycles under identical conditions.

Q: What is the inventory status of each part?

A: The D6L90 (obsolete) has 919 pcs available. The D6L90 F1 LFS (active) has 266,433 pcs in stock, providing significantly greater procurement flexibility and supply continuity.
