Substitute Part Grouping Explanation

Substitution of the LW1A-F-R is determined by strict alignment of the following parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility within the LW series ecosystem)
• Category: Configurable Switch Components (functional classification must remain identical)
• Color: Red (optical output specification must match)
• Shape: Round (mechanical form factor must be compatible)
• Compatible Series: IDEC, LW (ensures mechanical and electrical fit within the same switch family)
• Moisture Sensitivity Level (MSL): Not Applicable (environmental specification remains consistent)

Substitute parts must satisfy all of these parameters to ensure direct functional and mechanical compatibility without design modification or system reconfiguration.

Parameter Comparison

Engineering Selection Recommendations

The LW1A-FR-K is the manufacturer-recommended substitute for the obsolete LW1A-F-R. Both parts satisfy identical electrical and mechanical parameters across all specified categories. The primary distinction is product status: the LW1A-F-R is Obsolete, while the LW1A-FR-K maintains Active status, indicating ongoing manufacturing support and availability assurance.

For new designs and system replacements, the LW1A-FR-K is the appropriate selection. For existing installations currently utilizing the LW1A-F-R, the LW1A-FR-K provides direct functional equivalence without requiring system modification or recalibration.

Frequently Asked Questions (FAQ)

Q: Can the LW1A-FR-K be used as a direct replacement for the LW1A-F-R?

A: Yes. Both parts are manufactured by IDEC, share identical color (Red) and shape (Round) specifications, are classified within the same Configurable Switch Components category, and are compatible with the IDEC LW series. The LW1A-FR-K is the manufacturer-recommended substitute.

Q: What is the primary reason for substitution?

A: The LW1A-F-R carries Obsolete product status, indicating discontinued production. The LW1A-FR-K maintains Active status and ensures continued availability and manufacturing support.

Q: Are there any environmental or compliance differences between these parts?

A: No. Both parts specify Moisture Sensitivity Level (MSL) as Not Applicable, indicating identical environmental classification and handling requirements.

Q: Will the LW1A-FR-K fit existing LW series switch assemblies designed for the LW1A-F-R?

A: Yes. Both parts are compatible with the IDEC LW series and share identical mechanical form factors (Round shape) and color specification (Red), ensuring mechanical and optical compatibility within the same switch family.

Q: Is inventory availability a consideration in the substitution decision?

A: Both parts maintain current inventory stock. The LW1A-F-R has 1074 units available, and the LW1A-FR-K has 988 units available. Selection should prioritize the LW1A-FR-K due to its Active product status and manufacturer recommendation.
