Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the MB403 series are determined by the following criteria:

Fixed Parameters (Must Match for Substitution):

• Base Type: Miniature Bayonet (BA9S)
• Size / Dimension: T - 3 1/4
• Color: Amber
• Wavelength: 592nm
• Millicandela Rating: 2180mcd
• Configuration: Single
• Series: MB403
• Manufacturer: Visual Communications Company (VCC)
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameter (Defines Substitution Grouping):

• Voltage - Forward (Vf) (Typ): 24V, 28V, or 48V

The MB403-A48-CW-BP operates at 48V. Substitute parts MB403-A24-CA and MB403-A28-CA provide equivalent functionality at reduced voltage ratings (24V and 28V respectively) for applications with different power supply requirements. All three parts maintain identical mechanical compatibility, optical output, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

MB403-A48-CW-BP Selection Criteria: Select this part for applications requiring 48V forward voltage operation. All three parts in this substitution group maintain Active product status and ROHS3 compliance, ensuring regulatory alignment and long-term availability.

MB403-A24-CA Selection Criteria: Select this part for applications requiring 24V forward voltage operation. This substitute maintains identical mechanical fit, optical output, and regulatory compliance as the main part.

MB403-A28-CA Selection Criteria: Select this part for applications requiring 28V forward voltage operation. This substitute maintains identical mechanical fit, optical output, and regulatory compliance as the main part.

Compliance Assurance: All parts in this substitution group are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component deployment in restricted substance environments.

Frequently Asked Questions (FAQ)

Q: Can MB403-A24-CA replace MB403-A48-CW-BP in my application?

A: MB403-A24-CA is a direct mechanical and optical substitute only if your application circuit operates at 24V. The parts are identical in all parameters except forward voltage rating. Direct substitution requires matching the voltage supply to the lamp's rated forward voltage.

Q: What is the primary difference between these substitute parts?

A: The only difference is the Voltage - Forward (Vf) rating: MB403-A48-CW-BP operates at 48V, MB403-A28-CA at 28V, and MB403-A24-CA at 24V. All other electrical, optical, and mechanical specifications are identical.

Q: Are all parts in this group mechanically interchangeable?

A: Yes. All parts share the same Miniature Bayonet (BA9S) base type and T - 3 1/4 physical dimension, ensuring mechanical compatibility with any socket designed for this form factor.

Q: Do these parts have identical optical output?

A: Yes. All parts deliver 2180 millicandela at 592nm wavelength (amber color), providing identical brightness and color characteristics.

Q: Are there any packaging differences between these parts?

A: No. All parts are supplied in Bulk packaging.

Q: Which part should I select for a new design?

A: Select the part whose forward voltage rating matches your application's power supply voltage. MB403-A48-CW-BP for 48V systems, MB403-A28-CA for 28V systems, or MB403-A24-CA for 24V systems.

Q: Are all parts ROHS3 compliant?

A: Yes. All parts in this substitution group are ROHS3 compliant and REACH unaffected.
