Substitute Part Grouping Explanation

Substitution eligibility for the 383-2UBGC/S400-A6 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Mounting Type: Through Hole (radial configuration)
• Lens Size: 5mm nominal diameter
• Voltage - Forward (Vf): 3.5V ±0.3V tolerance range
• Current - Test: 20mA standard test condition
• Wavelength - Dominant: 505nm ±10nm acceptable range
• Lens Transparency: Clear
• Package / Case: Radial

Secondary Compatibility Criteria:

• Height (Max): 8.85mm to 8.91mm acceptable range
• Viewing Angle: 6° to 30° acceptable for indication applications
• Millicandela Rating: 7000mcd to 23000mcd acceptable range

The identified substitute parts meet these criteria while maintaining active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

OVLGC0C6B9 (TT Electronics/Optek Technology): This substitute maintains identical wavelength (505nm) and test current (20mA) specifications. Forward voltage is 3.2V, which is within acceptable tolerance for 3.5V nominal applications. The component is ROHS3 compliant and carries active product status with unlimited moisture sensitivity rating. Millicandela rating of 23000mcd exceeds the original specification, providing increased luminous intensity. Viewing angle of 15° is wider than the original 6°, suitable for applications requiring broader light distribution. Height and lens size remain within acceptable mechanical envelope.

VAOL-5GSBY4 (Visual Communications Company - VCC): This substitute maintains identical forward voltage (3.5V) and test current (20mA). Wavelength is 470nm, representing a shift from the original 505nm blue to a shorter-wavelength blue spectrum. Millicandela rating of 7000mcd is comparable to the original 8000mcd specification. Viewing angle of 30° provides significantly wider light distribution. Lens diameter is 4.80mm, slightly smaller than the original 5.00mm. The component is ROHS3 compliant and carries active product status. Moisture sensitivity level is MSL 2 (1 Year), requiring controlled storage conditions compared to the original MSL 1 (Unlimited).

Both substitutes are suitable for direct replacement in through-hole PCB applications where the specified electrical and mechanical parameters are compatible with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can OVLGC0C6B9 be used as a direct replacement for 383-2UBGC/S400-A6?

A: Yes. Both components operate at 20mA test current with identical 505nm dominant wavelength. Forward voltage difference (3.2V vs 3.5V) is within acceptable tolerance for LED indication circuits. Physical dimensions are compatible within the 5mm through-hole package envelope. The higher millicandela rating (23000mcd vs 8000mcd) provides increased brightness without affecting circuit compatibility.

Q: What is the primary difference between OVLGC0C6B9 and VAOL-5GSBY4?

A: The primary difference is wavelength specification. OVLGC0C6B9 maintains the original 505nm blue wavelength, while VAOL-5GSBY4 operates at 470nm, a shorter-wavelength blue. OVLGC0C6B9 has a narrower viewing angle (15° vs 30°), making it more suitable for directional indication applications. VAOL-5GSBY4 has a slightly smaller lens diameter (4.80mm vs 5.00mm) and requires MSL 2 storage conditions.

Q: Are there mechanical compatibility concerns with these substitutes?

A: No. All three components use through-hole radial mounting with 5mm nominal lens sizes and heights within 8.85mm to 8.91mm range. PCB footprints and lead spacing are compatible. Lens transparency (clear) and configuration (round with domed top) are identical across all parts.

Q: What compliance certifications apply to the substitute parts?

A: Both OVLGC0C6B9 and VAOL-5GSBY4 are ROHS3 compliant and REACH unaffected. The original 383-2UBGC/S400-A6 is REACH unaffected with no RoHS specification provided. All three components carry EAR99 ECCN classification and 8541.41.0000 HTSUS code.

Q: Does the viewing angle difference affect circuit performance?

A: Viewing angle affects light distribution characteristics but not electrical circuit performance. The original 6° narrow angle is suitable for focused indication. OVLGC0C6B9 at 15° provides moderate distribution, while VAOL-5GSBY4 at 30° provides wide distribution. Selection depends on application-specific optical requirements, not electrical compatibility.

Q: What is the impact of millicandela rating differences?

A: Millicandela rating indicates luminous intensity. OVLGC0C6B9 at 23000mcd is significantly brighter than the original 8000mcd, while VAOL-5GSBY4 at 7000mcd is slightly dimmer. Circuit current limiting resistor values may require adjustment to maintain consistent brightness levels in the application. Electrical circuit compatibility remains unchanged.

Q: Are there storage or handling differences between these parts?

A: OVLGC0C6B9 and the original 383-2UBGC/S400-A6 both have MSL 1 (Unlimited) rating, allowing indefinite storage without moisture control. VAOL-5GSBY4 has MSL 2 (1 Year) rating, requiring controlled storage conditions and baking procedures if storage exceeds one year or if moisture exposure occurs.
