Substitute Part Grouping Explanation

Substitute parts for the MB403-G48-CW-BP are identified based on strict parameter equivalence within the MB403 series. The substitution logic is governed by the following criteria:

Fixed Parameters (Must Match Exactly):

• Base Type: Miniature Bayonet (BA9S)
• Size / Dimension: T-3 1/4
• Color: Green
• Wavelength: 520nm
• Millicandela Rating: 2400mcd
• Configuration: Single
• Series: MB403
• Manufacturer: Visual Communications Company (VCC)
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameter (Substitution Basis):

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

The MB403-G48-CW-BP operates at 48V. Substitute parts MB403-G24-CG and MB403-G28-CG provide equivalent functionality at reduced voltage levels (24V and 28V respectively) while maintaining all other electrical and optical specifications. Selection of substitute parts depends solely on the voltage requirement of the target application circuit.

Parameter Comparison

Engineering Selection Recommendations

Selection between MB403-G48-CW-BP and its substitute parts is determined by application voltage requirements:

MB403-G48-CW-BP Selection Criteria: Use this part in circuits designed for 48V forward voltage operation. Product status is active with full inventory availability (887 units). ROHS3 compliance and REACH unaffected status confirm regulatory alignment for industrial and commercial applications.

MB403-G24-CG Selection Criteria: Use this part in circuits designed for 24V forward voltage operation. Product status is active with 851 units in stock. Identical compliance certifications (ROHS3 Compliant, REACH Unaffected) ensure equivalent regulatory standing.

MB403-G28-CG Selection Criteria: Use this part in circuits designed for 28V forward voltage operation. Product status is active with highest inventory availability (1049 units). Compliance certifications match the main part and other substitutes.

All three parts maintain identical optical output (2400mcd at 520nm green wavelength), mechanical form factor (T-3 1/4 miniature bayonet), and regulatory compliance. Selection is based exclusively on the target circuit voltage specification.

Frequently Asked Questions (FAQ)

Q: Can MB403-G24-CG be used in place of MB403-G48-CW-BP?

A: No. The MB403-G24-CG operates at 24V forward voltage, while MB403-G48-CW-BP requires 48V. Direct substitution without circuit voltage modification will result in component failure or non-operation. Use MB403-G24-CG only in applications designed for 24V operation.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical mechanical specifications: T-3 1/4 form factor and miniature bayonet (BA9S) base type. Physical installation in the same socket is possible. However, electrical compatibility with the circuit voltage is mandatory.

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

A: There is no optical output difference. All three parts deliver 2400mcd at 520nm green wavelength. Brightness and color characteristics are identical across all voltage variants.

Q: Are these parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for industrial component use.

Q: Which part has the best inventory availability?

A: MB403-G28-CG has the highest inventory with 1049 units in stock, followed by MB403-G48-CW-BP with 887 units, and MB403-G24-CG with 851 units. All parts are available as new original stock.

Q: Can I use MB403-G28-CG as a substitute for MB403-G48-CW-BP?

A: No. The MB403-G28-CG operates at 28V forward voltage. It is not electrically compatible with a 48V circuit. Use only the voltage-matched part for your application.

Q: What applications are these parts designed for?

A: All three parts are rated for general purpose lighting applications requiring miniature bayonet lamp replacements. Specific application compatibility depends on the circuit voltage specification.
