Key Parameters

Substitute Part Grouping Explanation

Substitution of the BP202-NFB28H is determined by the following critical parameters that must remain consistent across equivalent parts:

Mechanical Compatibility Parameters:

• Form factor: T-1 3/4
• Base type: Bi-Pin
• Configuration: Single

Optical Parameters:

• Color: Blue
• Wavelength: 465nm
• Millicandela rating: 168mcd

Electrical Parameters:

• Forward voltage (Vf): Determines circuit compatibility and must be matched to the application circuit design

Compliance Parameters:

• RoHS3 compliance status
• ECCN and HTSUS classifications

The BP202-NFB24H substitute part maintains identical mechanical, optical, and compliance characteristics. The primary difference is the forward voltage specification (24V versus 28V), which requires circuit-level evaluation for substitution feasibility.

Parameter Comparison

Engineering Selection Recommendations

The BP202-NFB24H is an active substitute for the obsolete BP202-NFB28H. Both parts share identical mechanical form factors, optical characteristics, and regulatory compliance status. The substitute part maintains ROHS3 compliance and identical ECCN/HTSUS classifications, ensuring regulatory continuity.

The primary technical distinction is the forward voltage specification: 24V for the substitute versus 28V for the original part. Selection of the BP202-NFB24H requires confirmation that the application circuit can operate at the reduced forward voltage without compromising system performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can the BP202-NFB24H directly replace the BP202-NFB28H in all applications?

A: Direct mechanical and optical replacement is possible due to identical form factor, base type, and light output characteristics. However, the 4V forward voltage difference requires circuit-level evaluation. The application must be designed to operate at 24V forward voltage for the substitute part.

Q: Are the mechanical dimensions identical between these parts?

A: Yes. Both parts use the T-1 3/4 form factor with bi-pin base configuration, ensuring identical mechanical fit and mounting compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the BP202-NFB28H and BP202-NFB24H are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

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

A: The BP202-NFB28H is classified as obsolete, indicating discontinued production. The BP202-NFB24H is active, ensuring ongoing availability for procurement and future applications.

Q: Are the optical characteristics identical?

A: Yes. Both parts produce blue light at 465nm wavelength with 168mcd millicandela rating, ensuring identical light output and color characteristics.

Q: What packaging options are available?

A: The BP202-NFB28H is available in standard packaging. The BP202-NFB24H is available in bulk packaging configuration.
