DF3GD LED Indicator Bar - Equivalent & Substitute Parts

Part Overview

The DF3GD is an active green LED circuit board indicator bar manufactured by Kingbright. This through-hole mounted component features a diffused, tinted lens with a rectangular flat-top design measuring 19.90mm x 6.80mm. The device operates at 2.2V with a 25mA current rating and delivers 34mcd brightness output at a peak wavelength of 565nm. The DF3GD is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial applications. Equivalent substitute parts are identified based on matching electrical specifications, mechanical compatibility, and regulatory compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF3GD are identified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Compatibility Criteria:

• Voltage Rating: 2.2V (exact match required)
• Peak Wavelength: 565nm (green spectrum, exact match required)
• Color: Green (exact match required)
• Mounting Type: Through Hole (exact match required)

Mechanical Compatibility Criteria:

• Lens Style: Rectangle with Flat Top (exact match required)
• Configuration: Bar - Single format (exact match required)

Regulatory & Environmental Criteria:

• RoHS3 Compliance (required)
• MSL Rating: 1 (Unlimited) (required)
• Product Status: Active (required)

The HLMP-2550 qualifies as a substitute part because it matches all critical electrical parameters (2.2V, 565nm green wavelength), maintains the same through-hole mounting type, preserves the rectangular flat-top lens style, and meets all regulatory requirements. Variations in current rating (30mA vs 25mA), millicandela output (50mcd vs 34mcd), lens dimensions, and configuration subtype (SIP vs DIP) are within acceptable substitution parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the DF3GD and HLMP-2550 are active products with ROHS3 compliance and unlimited moisture sensitivity ratings, confirming their suitability for current production and long-term availability. The HLMP-2550 operates at a higher current specification (30mA vs 25mA) and delivers increased brightness output (50mcd vs 34mcd) while maintaining identical voltage and wavelength characteristics. Circuit design must accommodate the higher current draw of the HLMP-2550 if selected as a substitute. Both components share identical through-hole mounting requirements and rectangular flat-top lens geometry, ensuring mechanical compatibility in standard PCB layouts. The HLMP-2550 is available in tube packaging with 1443 units in stock, compared to the DF3GD's 1004 units. Selection between these parts should be based on circuit current capacity, desired brightness level, and packaging requirements.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-2550 directly replace the DF3GD in existing circuit designs?

A: The HLMP-2550 is electrically compatible at the 2.2V operating voltage and 565nm wavelength. However, the higher current specification (30mA vs 25mA) requires verification that the circuit's current-limiting resistor and power supply can accommodate the increased draw. Mechanical compatibility is confirmed through identical mounting type and lens geometry.

Q: What are the key differences between the DF3GD and HLMP-2550?

A: The primary differences are configuration type (DIP vs SIP), current rating (25mA vs 30mA), brightness output (34mcd vs 50mcd), and lens dimensions (19.90mm x 6.80mm vs 19.05mm x 3.81mm). All other critical parameters including voltage, wavelength, color, and mounting type are identical.

Q: Are both parts compliant with current regulatory standards?

A: Both the DF3GD and HLMP-2550 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) ratings. Both maintain active product status with manufacturers.

Q: What packaging options are available for these parts?

A: The DF3GD is supplied in standard packaging format. The HLMP-2550 is supplied in tube packaging. Verify packaging requirements for your assembly process before selection.

Q: Can I use the HLMP-2550 if my circuit is designed for lower brightness output?

A: The HLMP-2550 delivers 50mcd compared to the DF3GD's 34mcd. If lower brightness is required, the DF3GD should be retained. If higher brightness is acceptable or beneficial, the HLMP-2550 is suitable.

Q: Are there any mechanical compatibility concerns with lens dimensions?

A: The HLMP-2550 has smaller lens dimensions (19.05mm x 3.81mm vs 19.90mm x 6.80mm). Verify that the PCB layout and mechanical housing accommodate the different lens size before substitution.
