Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the MB403 series are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Base Type: Miniature Bayonet (BA9S)
• Size / Dimension: T-3 1/4
• Voltage - Forward (Vf): 120VAC
• Color: Red
• Wavelength: 634nm
• Millicandela Rating: 2180mcd
• Configuration: Single
• Series: MB403

All substitute parts must match these parameters exactly to ensure direct compatibility in existing socket installations and circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MB403-R120-CW-BP and MB403-R120-CR are active-status products manufactured by VCC within the same MB403 series. Both parts meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications.

Selection between these parts is based on inventory availability and packaging requirements. The MB403-R120-CW-BP is available in bulk packaging with 1119 pieces in stock. The MB403-R120-CR is also available in bulk packaging with 831 pieces in stock.

Both parts are electrically and mechanically identical across all specified parameters, including 120VAC operation, BA9S miniature bayonet base, T-3 1/4 form factor, red color at 634nm wavelength, and 2180mcd brightness rating.

Frequently Asked Questions (FAQ)

Q: Can MB403-R120-CR replace MB403-R120-CW-BP in existing installations?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. They share identical base type (BA9S), voltage rating (120VAC), form factor (T-3 1/4), color (red), wavelength (634nm), and brightness rating (2180mcd).

Q: What determines compatibility between these substitute parts?

A: Compatibility is determined by matching the following parameters: miniature bayonet base type, T-3 1/4 physical dimension, 120VAC voltage rating, red color specification, 634nm wavelength, and 2180mcd millicandela rating. Both parts meet these criteria.

Q: Are there compliance differences between MB403-R120-CW-BP and MB403-R120-CR?

A: No. Both parts carry identical compliance certifications: ROHS3 compliant and REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS code 8541.41.0000.

Q: What is the difference between these two part numbers?

A: The parts are functionally equivalent. Differences exist only in part number designation and packaging reference. Both are active-status products from the same MB403 series with identical electrical and mechanical specifications.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and internal part number standardization practices. Both parts provide identical performance and compliance characteristics.
