Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5381H5LC requires evaluation of the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Green wavelength emission (565nm peak for 5381H5LC; 527nm dominant for CreeLED alternatives)
• Lens Configuration: Round with domed top geometry and 5mm diameter
• Mounting Type: Through-hole radial termination
• Electrical Ratings: Forward voltage (Vf) and test current specifications
• Optical Output: Millicandela rating for brightness level
• Compliance: RoHS3 compliance and MSL rating

Substitution Logic:

The 5381H5LC operates at 1.8V/7mA with 2.3mcd output. Direct electrical equivalents are not available among the provided substitute parts. The CreeLED C503B series parts operate at 3.2V/20mA with significantly higher brightness (14,680mcd to 15,850mcd), requiring circuit redesign for voltage and current compatibility. The Dialight 6052211110F operates at 2V/15mA, also requiring circuit modification.

Substitutes are grouped by:

1. CreeLED C503B variants (primary substitutes): Multiple configurations with different lens heights (10.30mm vs 12.70mm) and packaging options
2. Dialight 6052211110F (alternative substitute): Panel indicator configuration with different electrical characteristics

All substitutes maintain green color, 5mm round domed lens geometry, through-hole mounting, RoHS3 compliance, and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Status Considerations:

All substitute parts maintain RoHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching the original 5381H5LC specifications. All substitutes are currently active products, ensuring long-term availability and supply chain stability compared to the obsolete original component.

Electrical Compatibility Requirements:

Direct pin-for-pin substitution is not possible due to voltage and current differences. The 5381H5LC operates at 1.8V/7mA, while all active substitutes require higher voltage and current:

• Dialight 6052211110F: 2V/15mA
• CreeLED C503B series: 3.2V/20mA

Circuit redesign is mandatory for any substitute implementation, including series resistor recalculation and voltage supply verification.

Mechanical Compatibility:

CreeLED C503B parts maintain 5mm round domed lens geometry matching the original. Two height variants are available:

• 10.30mm maximum height (C503B-GCN variants)
• 12.70mm maximum height (C503B-GCS variants)

Height selection depends on available PCB clearance. The Dialight 6052211110F features a flat-top lens and larger 6.35mm panel cutout, requiring mechanical redesign for board-level integration.

Brightness Considerations:

The 5381H5LC provides 2.3mcd output. CreeLED substitutes deliver 14,680mcd to 15,850mcd, representing approximately 6,400 to 6,900 times greater brightness. Dialight 6052211110F provides 72mcd, approximately 31 times greater brightness. Optical filtering or current limiting may be required to match original visual intensity in applications where brightness consistency is critical.

Recommended Substitution Priority:

1. Primary: CreeLED C503B-GCN or C503B-GCS series (height-dependent selection)
2. Secondary: Dialight 6052211110F (if panel mount configuration is acceptable)

Frequently Asked Questions (FAQ)

Q: Can the 5381H5LC be directly replaced without circuit modification?

A: No. The 5381H5LC operates at 1.8V/7mA, while all active substitutes require higher voltage (2V to 3.2V) and current (15mA to 20mA). Series resistor values and voltage supply specifications must be recalculated for each substitute part.

Q: What is the difference between CreeLED C503B-GCN and C503B-GCS variants?

A: The primary difference is maximum height: C503B-GCN variants have 10.30mm maximum height, while C503B-GCS variants have 12.70mm maximum height. Both maintain identical electrical specifications (3.2V/20mA), lens geometry (5mm round domed top), and optical output (14,680mcd or 15,850mcd depending on specific part number). Selection depends on available PCB clearance and component placement constraints.

Q: Are there packaging differences among the CreeLED substitutes?

A: Yes. CreeLED C503B parts are available in two packaging options: Bulk and Tape & Box (TB). Bulk packaging is suitable for standard component storage and manual assembly. Tape & Box packaging is designed for automated pick-and-place equipment. Electrical and optical specifications are identical between packaging variants.

Q: Why is the CreeLED C503B series significantly brighter than the original 5381H5LC?

A: The 5381H5LC provides 2.3mcd output, while CreeLED C503B parts deliver 14,680mcd to 15,850mcd. This brightness difference reflects advances in LED technology and different design objectives. The original VCC component was optimized for low-power indicator applications, while CreeLED parts are designed for higher-visibility applications. Circuit design must account for this brightness differential through appropriate current limiting or optical filtering.

Q: Is the Dialight 6052211110F a suitable substitute for through-hole PCB mounting?

A: The Dialight 6052211110F is configured as a panel indicator with a round flat-top lens and 6.35mm panel cutout. While it maintains green color, through-hole mounting capability, and RoHS3 compliance, it requires mechanical redesign for board-level integration. This part is recommended only if panel mount configuration is acceptable for the application.

Q: Do all substitutes maintain the same wavelength as the original 5381H5LC?

A: No. The 5381H5LC has a peak wavelength of 565nm. CreeLED C503B substitutes have a dominant wavelength of 527nm, representing a shift toward shorter wavelengths within the green spectrum. This wavelength difference may be perceptible in applications where color consistency is critical. The Dialight 6052211110F wavelength is not specified in available documentation.

Q: Are all substitutes RoHS3 compliant?

A: Yes. The 5381H5LC and all listed substitutes (Dialight 6052211110F and CreeLED C503B series) are RoHS3 compliant. All parts maintain MSL 1 (unlimited) moisture sensitivity rating, ensuring compatibility with standard storage and handling procedures.

Q: What is the viewing angle specification for the substitutes?

A: The original 5381H5LC viewing angle is not specified. CreeLED C503B substitutes specify 30° viewing angle. The Dialight 6052211110F viewing angle is not specified. Viewing angle should be verified against application requirements for indicator visibility in the intended mounting orientation.

Q: Can multiple CreeLED C503B part numbers be used interchangeably in the same application?

A: CreeLED C503B parts with identical electrical specifications (voltage, current) and optical output (millicandela rating) can be used interchangeably, provided height constraints are satisfied. Parts with different millicandela ratings (14,680mcd vs 15,850mcd) will produce different brightness levels and should not be mixed in applications requiring uniform visual indication across multiple indicators.
