Key Parameters

Substitute Part Grouping Explanation

Substitution within the MB403 series is determined by the following parameters that must remain constant across all equivalent parts:

Fixed Parameters (Must Match):

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

Variable Parameter (Substitution Basis):

• Voltage - Forward (Vf) Typical: 24V, 28V, or 60V

The MB403-A60-CW-BP can be substituted with MB403-A24-CA or MB403-A28-CA when the circuit voltage requirement differs from 60V. Each substitute maintains identical mechanical fit, optical output, and regulatory compliance while operating at alternative voltage levels.

Parameter Comparison

Engineering Selection Recommendations

Selection between MB403-A60-CW-BP, MB403-A24-CA, and MB403-A28-CA is determined solely by the circuit voltage requirement:

MB403-A60-CW-BP: Select this part for circuits operating at 60V forward voltage. All three parts are active products with full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance across all voltage variants.

MB403-A24-CA: Select this part for circuits operating at 24V forward voltage. This variant maintains identical mechanical and optical specifications with 936 units currently in stock.

MB403-A28-CA: Select this part for circuits operating at 28V forward voltage. This variant maintains identical mechanical and optical specifications with 604 units currently in stock.

All three parts share identical base type (BA9S), form factor (T-3 1/4), color (Amber), wavelength (592nm), and luminous intensity (2180mcd). Substitution is valid only when the replacement part voltage rating matches the circuit design voltage.

Frequently Asked Questions (FAQ)

Q: Can MB403-A24-CA be used in place of MB403-A60-CW-BP?

A: No. The MB403-A24-CA operates at 24V forward voltage, while MB403-A60-CW-BP operates at 60V. Direct substitution without circuit modification will result in incorrect lamp operation. The replacement part must match the circuit voltage specification.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical base type (Miniature Bayonet BA9S), form factor (T-3 1/4), and mounting characteristics. Mechanical interchangeability is confirmed. Electrical compatibility depends on circuit voltage matching.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. MB403-A60-CW-BP, MB403-A24-CA, and MB403-A28-CA are all ROHS3 compliant and REACH unaffected. All parts carry identical regulatory status.

Q: What is the optical output difference between these parts?

A: There is no optical output difference. All three parts deliver 2180 millicandela at 592nm wavelength (amber color). Optical performance is identical across all voltage variants.

Q: Which substitute part has the best availability?

A: MB403-A60-CW-BP has the highest inventory with 941 units in stock, followed by MB403-A24-CA with 936 units, and MB403-A28-CA with 604 units. All parts are currently in stock.

Q: Can these parts be used interchangeably in the same circuit?

A: No. Each part is designed for a specific voltage level. Using a part rated for a different voltage than the circuit design will cause malfunction. Voltage matching is mandatory for proper operation.

Q: Are there any packaging differences between the substitute parts?

A: No. All three parts are supplied in bulk packaging. Packaging format is identical across all variants.
