Parameter Comparison

Engineering Selection Recommendations

The Dialight 5855456F is the direct substitute for the obsolete 5855456. Both components share identical electrical specifications (120VAC, 585nm, 220mcd) and mechanical form factors (T-3 1/4 bayonet base). The primary distinction is product status and compliance: 5855456F is an active component with ROHS3 compliance, whereas the original 5855456 is obsolete and RoHS non-compliant. For new designs or system replacements, 5855456F is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can 5855456F directly replace 5855456 in existing applications?

A: Yes. Both components are electrically and mechanically identical, with matching wavelength (585nm), voltage rating (120VAC), base type (bayonet), form factor (T-3 1/4), and luminous intensity (220mcd). The substitute is suitable for direct socket replacement.

Q: What is the significance of the product status difference?

A: The original 5855456 is obsolete and no longer manufactured. The 5855456F is an active product with current manufacturing support and improved compliance certifications (ROHS3).

Q: Are there packaging differences between these parts?

A: The original 5855456 has unspecified packaging (-), while 5855456F is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet current regulatory requirements?

A: The 5855456F meets ROHS3 compliance standards. The original 5855456 is RoHS non-compliant. Both maintain REACH Unaffected status. For applications requiring RoHS compliance, 5855456F is the appropriate selection.

Q: What applications are these components suitable for?

A: Both parts are designed for incandescent lamp replacement and indicator light applications requiring 120VAC yellow LED illumination with bayonet base mounting.
