Mechanical Parameters:

• Panel cutout shape: Round
• Panel cutout dimensions: 0.29" (7.37mm)
• Lens size: 8.50mm diameter
• Lens style: Round with flat top
• Termination style: PC pin

Optical Parameters:

• Lamp color: Green
• Lens color: Green
• Lens transparency: Clear
• Viewing angle: 24°
• Millicandela rating: 70mcd

Compliance Parameters:

• RoHS3 compliance
• ECCN classification: EAR99

The substitute part 91-BCG28H-CGO meets all these criteria and is classified as active, providing direct functional and mechanical compatibility with the obsolete C91-BCG28H-CGO.

Parameter Comparison

Engineering Selection Recommendations

The 91-BCG28H-CGO is the direct active equivalent for the obsolete C91-BCG28H-CGO. All electrical, mechanical, and optical parameters are identical. The substitute part maintains ROHS3 compliance and carries the same ECCN and HTSUS classifications, ensuring regulatory and trade compliance equivalence.

The primary distinction is product status: the C91-BCG28H-CGO is obsolete while the 91-BCG28H-CGO is active. This substitution is appropriate for both replacement applications in existing systems and for new designs requiring this LED panel indicator specification.

Frequently Asked Questions (FAQ)

Q: Can the 91-BCG28H-CGO directly replace the C91-BCG28H-CGO in existing assemblies?

A: Yes. The 91-BCG28H-CGO is a parametric equivalent with identical electrical ratings (28V, 16.5mA), mechanical dimensions (0.29" round cutout, 8.50mm lens diameter), optical characteristics (70mcd, 569nm peak wavelength, 24° viewing angle), and termination style (PC pin). No circuit modifications or panel redesign are required.

Q: What is the difference between C91-BCG28H-CGO and 91-BCG28H-CGO?

A: The parts are electrically and mechanically identical. The primary difference is product status: C91-BCG28H-CGO is obsolete, while 91-BCG28H-CGO is active. The packaging differs (C91 variant uses standard packaging; 91 variant uses bulk packaging), but functional performance is equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both C91-BCG28H-CGO and 91-BCG28H-CGO are ROHS3 compliant, meeting environmental and regulatory requirements for electronic components.

Q: What panel cutout dimensions are required for installation?

A: Both parts require a 0.29" (7.37mm) round panel cutout. The lens diameter is 8.50mm with a round flat-top style. Panel thickness and mounting tolerance specifications should be verified against the mechanical drawing for your specific application.

Q: Can these parts be used in new designs?

A: The 91-BCG28H-CGO is the appropriate choice for new designs, as it carries active product status. The C91-BCG28H-CGO is obsolete and should not be specified for new applications.

Q: What is the viewing angle specification?

A: Both parts have a 24° viewing angle, defining the cone of light emission from the LED indicator. This parameter is critical for applications requiring specific directional visibility.

Q: Are there any differences in brightness between the two parts?

A: No. Both parts have identical millicandela ratings of 70mcd at the specified operating current of 16.5mA maximum, ensuring equivalent optical output.
