Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VAOS-C301G9-BW/40 is determined by strict alignment with the following core parameters:

Critical Matching Parameters:

• Display Type: 7-Segment LED
• Number of Characters: 1
• Digit Height: 0.30" (7.62mm)
• Common Pin Configuration: Common Cathode
• Color: Green
• Package Type: 14-DIP (0.300", 7.62mm)
• Wavelength - Peak: 565nm

Allowable Variation Parameters:

• Forward Voltage (Vf): Within ±0.2V tolerance
• Test Current: 20mA standard
• Power Dissipation: Variation acceptable if within device thermal limits
• Millicandela Rating: Higher brightness acceptable for direct substitution
• Physical Dimensions: Tolerance within ±0.010" for height and width; ±0.025" for depth

The SC03-12GWA manufactured by Kingbright meets all critical matching parameters and falls within allowable variation ranges for electrical characteristics.

Engineering Selection Recommendations

Primary Substitute: SC03-12GWA (Kingbright)

The SC03-12GWA is the qualified equivalent for the obsolete VAOS-C301G9-BW/40. Selection is based on the following engineering criteria:

Product Status Consideration: The VAOS-C301G9-BW/40 carries an obsolete product status, necessitating transition to an active production component. The SC03-12GWA maintains active product status with confirmed inventory availability (1053 pieces in stock), ensuring supply chain continuity.

Compliance and Certification Alignment: Both components maintain identical regulatory compliance profiles:

• ROHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8541.41.0000

Electrical Parameter Compatibility: The SC03-12GWA operates within acceptable electrical parameters for direct substitution. The forward voltage differential of +0.1V (2.2V vs. 2.1V) remains within standard circuit design tolerances. The increased millicandela rating (11mcd vs. 3.5mcd) provides enhanced brightness without requiring circuit modification. Power dissipation is lower (62.5mW vs. 70mW), reducing thermal load on the host circuit.

Mechanical Compatibility: Physical dimensions align within standard manufacturing tolerances. The 14-DIP package footprint is identical, enabling direct PCB mounting without layout revision.

Frequently Asked Questions (FAQ)

Q: Can the SC03-12GWA be used as a direct replacement for the VAOS-C301G9-BW/40 without circuit modification?

A: Yes. The SC03-12GWA is electrically and mechanically compatible for direct substitution. The forward voltage increase of 0.1V falls within standard circuit design margins. No resistor value recalculation is required for typical LED current-limiting applications.

Q: What is the significance of the higher millicandela rating in the SC03-12GWA?

A: The SC03-12GWA provides 11mcd brightness compared to 3.5mcd in the original part. This represents increased light output without additional current draw. In applications where brightness is critical, this substitution improves display visibility. In applications with brightness-sensitive design constraints, the higher output does not create incompatibility; it simply exceeds the minimum requirement.

Q: Are there any packaging differences between these components?

A: Both components use 14-DIP (0.300", 7.62mm) packaging. Physical dimensions are within standard manufacturing tolerances. The SC03-12GWA is supplied in tube packaging, while the original part was supplied in standard packaging. This does not affect functional compatibility or PCB mounting.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the VAOS-C301G9-BW/40 and SC03-12GWA are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings. They share the same ECCN and HTSUS classifications, ensuring equivalent regulatory treatment in procurement and supply chain documentation.

Q: What is the wavelength specification, and does it differ between parts?

A: Both components specify 565nm peak wavelength, which corresponds to green light emission. This wavelength is identical across both parts, ensuring consistent color appearance in display applications.

Q: Is the SC03-12GWA available for immediate procurement?

A: The SC03-12GWA is classified as active product status with 1053 pieces confirmed in stock, indicating immediate availability for procurement and production use.
