Equivalent & Substitute Parts for 405-BG12H-O

Part Overview

The 405-BG12H-O is a panel-mount LED indicator manufactured by Visual Communications Company (VCC). This component is a green LED designed for 12V DC applications with a 0.25" (6.35mm) round panel cutout and PC pin termination. The product is classified as obsolete, making identification of suitable substitute components necessary for ongoing maintenance, repair, and new design applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 405-BG12H-O is determined by the following critical parameters:

Electrical Compatibility:

• Voltage rating of 12V (DC or AC/DC rated)
• Current rating of 20mA maximum
• Green lamp color with peak wavelength in the 565nm range

Mechanical Compatibility:

• Round panel cutout configuration
• PC pin termination style for direct circuit board connection
• Physical dimensions permitting installation in 0.25" (6.35mm) cutout apertures

Regulatory Compliance:

• ROHS3 compliance requirement
• EAR99 export classification
• HTSUS code 8541.41.0000

The substitute part FL1M-8SJ-3-G12V meets the electrical and regulatory requirements. However, mechanical differences exist in panel cutout dimensions (0.31" versus 0.25") and viewing angle (180° versus 60°), which must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Electrical Compatibility: The FL1M-8SJ-3-G12V substitute operates at the same 12V rating and 20mA current specification as the 405-BG12H-O. Both components are ROHS3 compliant and share identical export classification (EAR99) and tariff codes, confirming regulatory alignment.

Mechanical Considerations: The substitute part requires a larger panel cutout (0.31" versus 0.25"). Panel modifications or adapter hardware may be necessary for direct installation in existing 0.25" apertures. The 180° viewing angle of the substitute provides wider light distribution compared to the 60° angle of the original part, which may alter visual indication characteristics in the application.

Product Status: The FL1M-8SJ-3-G12V is an active product with confirmed inventory availability (720 units), whereas the 405-BG12H-O is obsolete. Selection of the active substitute ensures long-term supply chain continuity and support.

Brightness Consideration: The substitute part exhibits significantly higher millicandela output (8000-10000mcd versus 10mcd), indicating substantially greater luminous intensity. This difference may require circuit-level current limiting adjustments to match the original visual indication intensity.

Frequently Asked Questions (FAQ)

Q: Can the FL1M-8SJ-3-G12V directly replace the 405-BG12H-O without panel modification?

A: Direct replacement without panel modification is not possible. The substitute requires a 0.31" (8.00mm) cutout versus the original 0.25" (6.35mm) specification. Panel drilling or enlargement is required, or an adapter bezel may be used.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both components operate at 12V with a 20mA maximum current rating and are designed for DC applications. The substitute additionally supports AC/DC operation.

Q: What is the significance of the viewing angle difference?

A: The 405-BG12H-O provides a 60° viewing angle, while the FL1M-8SJ-3-G12V provides 180°. The wider angle of the substitute allows visibility from a broader range of positions. Applications requiring narrow-angle indication may experience unintended visibility changes.

Q: Why is the millicandela rating so different?

A: The 405-BG12H-O is rated at 10mcd, while the FL1M-8SJ-3-G12V ranges from 8000-10000mcd. This represents a 800-1000x increase in luminous intensity. Circuit current limiting may be necessary to achieve equivalent visual brightness in the application.

Q: Are both parts RoHS compliant?

A: Yes. Both the 405-BG12H-O and FL1M-8SJ-3-G12V are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the IP65 rating on the substitute part?

A: IP65 indicates ingress protection against dust and water jets. The original part specification does not include an ingress protection rating. The substitute provides enhanced environmental protection suitable for applications requiring moisture or dust resistance.

Q: Can I use the FL1M-8SJ-3-G12V in new designs?

A: Yes. The FL1M-8SJ-3-G12V is an active product with confirmed availability. It is suitable for new designs requiring 12V green LED panel indicators with PC pin termination, provided mechanical panel cutout dimensions and viewing angle requirements are compatible with the 0.31" (8.00mm) specification and 180° angle.
