• Voltage - Forward (Vf) (Typ): 37.5V
• Configuration: Single
• Applications: General Purpose Lighting

The substitute part 5855227F maintains identical electrical and mechanical specifications while offering active product status and improved compliance certification. Both parts belong to the Dialight 585 series and are functionally interchangeable within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5855227F serves as the direct substitute for the obsolete 5855227. Selection between these parts should be based on the following criteria:

For new designs or systems requiring regulatory compliance, the 5855227F is the appropriate choice due to its active product status and ROHS3 compliance certification. The 5855227F maintains full electrical and mechanical compatibility while offering improved environmental compliance.

For legacy system maintenance where existing inventory of 5855227 is available, continued use is permissible provided the application does not impose new RoHS or environmental compliance requirements.

Both parts carry identical REACH Unaffected and EAR99 ECCN classifications, with Moisture Sensitivity Level 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can 5855227F directly replace 5855227 in existing applications?

A: Yes. The 5855227F maintains identical electrical specifications (37.5V forward voltage), mechanical form factor (T-3 1/4), base type (BA9S miniature bayonet), and color (red). Direct substitution is supported without circuit modification.

Q: What is the primary difference between 5855227 and 5855227F?

A: The 5855227F is the active production variant with ROHS3 compliance, while the 5855227 is obsolete and RoHS non-compliant. Both are functionally equivalent for electrical and mechanical purposes.
