Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HLMP-ED33-SVTDD are selected based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Red color LED indication function
• Through-hole radial mounting configuration
• Clear lens transparency
• Round domed lens style
• Forward voltage range: 2.1V to 2.4V
• Test current: 20mA
• Wavelength range: 625nm to 660nm (red spectrum)
• Viewing angle: 30° to 34°
• MSL rating: 1 (Unlimited)
• REACH and ECCN compliance maintained

Substitute Categories:

Category 1 - Direct Form Factor Match (5mm T-1 3/4):

• HLMP-EG3A-WX0DD (Broadcom Limited) - Active product status, higher brightness (7400mcd), lower forward voltage (2.1V), compatible wavelength (626nm)

Category 2 - Alternative Form Factor (5mm T-5MM):

• SSL-LX5093SRC39240 (Lumex Opto/Components Inc.) - Active product status, 660nm wavelength, bulk packaging

Category 3 - Reduced Form Factor (3mm T-1):

• WP710A10SECK/J3 (Kingbright) - Active product status, smaller lens size (3mm T-1), lower brightness (1600mcd), compatible wavelength (625nm), higher viewing angle (34°)

Engineering Selection Recommendations

HLMP-EG3A-WX0DD (Broadcom Limited) - Recommended Primary Substitute

This part provides the closest form factor match with identical 5mm T-1 3/4 lens size and through-hole radial mounting. The HLMP-EG3A-WX0DD maintains active product status with ROHS3 compliance and REACH unaffected designation. The forward voltage of 2.1V is lower than the original 2.4V, requiring circuit verification for current-limiting resistor adjustment. The brightness rating of 7400mcd exceeds the original 3700mcd specification. The wavelength of 626nm remains within the red spectrum range. Cut tape packaging provides standard component handling.

SSL-LX5093SRC39240 (Lumex Opto/Components Inc.) - Alternative Substitute

This part maintains active product status with ROHS3 compliance and REACH unaffected designation. The 5mm T-5MM form factor provides compatibility with standard 5mm LED mounting holes. The 660nm wavelength is at the longer end of the red spectrum. Bulk packaging is suitable for high-volume applications. Specific forward voltage and brightness ratings are not provided in available documentation.

WP710A10SECK/J3 (Kingbright) - Reduced Form Factor Substitute

This part is suitable for applications where a smaller 3mm T-1 lens size is acceptable. The component maintains active product status with ROHS3 compliance and REACH unaffected designation. The forward voltage of 2.2V is compatible with standard LED circuit designs. The brightness rating of 1600mcd is lower than the original specification, suitable for applications with reduced brightness requirements. The 34° viewing angle provides a wider field of view compared to the original 30°. Bulk packaging supports high-volume procurement.

Frequently Asked Questions (FAQ)

Q: Can HLMP-EG3A-WX0DD be used as a direct replacement for HLMP-ED33-SVTDD?

A: Yes, the HLMP-EG3A-WX0DD is a direct form factor replacement with identical 5mm T-1 3/4 lens size and through-hole radial mounting. The lower forward voltage (2.1V vs. 2.4V) requires verification of the current-limiting resistor value in the circuit design. The higher brightness (7400mcd vs. 3700mcd) may require optical diffusion consideration depending on application requirements.

Q: What are the key differences between the substitute parts?

A: HLMP-EG3A-WX0DD maintains identical form factor with improved brightness and lower forward voltage. SSL-LX5093SRC39240 offers alternative 5mm form factor with longer wavelength (660nm). WP710A10SECK/J3 provides a smaller 3mm lens size with reduced brightness and wider viewing angle. Selection depends on specific application requirements for lens size, brightness, and wavelength.

Q: Are all substitute parts RoHS compliant?

A: HLMP-EG3A-WX0DD, SSL-LX5093SRC39240, and WP710A10SECK/J3 are all ROHS3 compliant. All parts maintain REACH unaffected status and EAR99 ECCN classification.

Q: What is the impact of forward voltage differences on circuit design?

A: The HLMP-ED33-SVTDD operates at 2.4V, while HLMP-EG3A-WX0DD operates at 2.1V and WP710A10SECK/J3 at 2.2V. These differences affect the current-limiting resistor calculation. For a given supply voltage and target current of 20mA, lower forward voltage results in higher resistor values. Circuit verification is required before substitution.

Q: Can WP710A10SECK/J3 be used in applications requiring 3700mcd brightness?

A: No. The WP710A10SECK/J3 has a brightness rating of 1600mcd, significantly lower than the original 3700mcd. This part is suitable only for applications with reduced brightness requirements or where the smaller 3mm lens size is a design priority.

Q: What packaging options are available for these substitute parts?

A: HLMP-EG3A-WX0DD is available in cut tape (CT) packaging. SSL-LX5093SRC39240 and WP710A10SECK/J3 are available in bulk packaging. Packaging selection affects component handling, storage, and automated assembly compatibility.

Q: Are there wavelength considerations when substituting these parts?

A: All substitute parts maintain red spectrum wavelengths within the 625nm to 660nm range. The original HLMP-ED33-SVTDD operates at 630nm dominant wavelength. HLMP-EG3A-WX0DD (626nm) and WP710A10SECK/J3 (625nm) provide closest wavelength match. SSL-LX5093SRC39240 (660nm) represents the longer wavelength option. Wavelength selection affects perceived color intensity and optical filtering compatibility.
