HLMP-ED31-RUT00 Equivalent & Substitute Parts

Part Overview

The HLMP-ED31-RUT00 is a red LED indication component manufactured by Broadcom Limited, featuring a 5mm T-1 3/4 through-hole package with 630nm dominant wavelength and 2850mcd brightness rating. This part is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility for red LED indication applications. Substitute parts must preserve the core electrical characteristics (forward voltage, test current, viewing angle) and mechanical compatibility (through-hole mounting, 5mm lens size, radial package configuration).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HLMP-ED31-RUT00 are selected based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Red
• Mounting Type: Through Hole
• Package Configuration: Radial
• Lens Size: 5mm or compatible T-1 form factor
• Voltage - Forward (Vf): Range 2.0V to 2.4V
• Current - Test: 20mA
• Viewing Angle: 30° or greater
• Wavelength - Dominant: Red spectrum (620nm to 640nm)

Regulatory & Environmental Criteria:

• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• RoHS Compliance: ROHS3 Compliant (preferred for active parts)

The three substitute parts listed (OVLFR3C7, SSL-LX5093SRC39240, WP710A10SECK/J3) meet these core criteria with variations in brightness rating and exact wavelength, which are acceptable within the red LED indication category.

Parameter Comparison

Engineering Selection Recommendations

OVLFR3C7 (TT Electronics/Optek Technology)

• Active product status with ROHS3 compliance
• Identical lens size (5mm, T-1 3/4) and viewing angle (30°) to original part
• Forward voltage 2.0V is within acceptable range for 2.4V design
• Higher brightness rating (7400mcd vs 2850mcd) provides increased luminous intensity
• Wavelength 623nm maintains red spectrum compatibility
• Recommended for direct replacement in applications where increased brightness is acceptable

SSL-LX5093SRC39240 (Lumex Opto/Components Inc.)

• Active product status with ROHS3 compliance
• 5mm lens size compatible with original package
• Wavelength 660nm at upper end of red spectrum
• Limited parameter specification; verify compatibility with specific application requirements

WP710A10SECK/J3 (Kingbright)

• Active product status with ROHS3 compliance
• Smaller lens size (3mm, T-1) and reduced height (5.90mm vs 8.91mm) may require PCB layout verification
• Forward voltage 2.2V is within acceptable range
• Lower brightness rating (1600mcd) compared to original part
• Wider viewing angle (34° vs 30°) provides enhanced visibility
• Suitable for space-constrained applications where reduced package size is beneficial

Frequently Asked Questions (FAQ)

Q: Can OVLFR3C7 be used as a direct replacement for HLMP-ED31-RUT00? A: Yes. OVLFR3C7 maintains identical lens size (5mm, T-1 3/4), viewing angle (30°), and mounting configuration. Forward voltage (2.0V) is compatible with circuits designed for 2.4V operation. The higher brightness rating (7400mcd) does not prevent substitution but should be verified against application requirements.

Q: What is the primary difference between WP710A10SECK/J3 and the original part? A: WP710A10SECK/J3 uses a smaller 3mm T-1 lens package with reduced overall height (5.90mm vs 8.91mm). This requires verification that PCB mounting holes and circuit board layout accommodate the different physical dimensions. Brightness is lower (1600mcd vs 2850mcd).

Q: Are all substitute parts RoHS compliant? A: Yes. All three substitute parts carry ROHS3 Compliant certification. The original HLMP-ED31-RUT00 does not specify RoHS status.

Q: Do wavelength differences affect substitution? A: Wavelength variations (623nm, 625nm, 660nm vs 630nm) remain within the red LED spectrum and are acceptable for indication applications. Visual color perception differences are minimal across this range.

Q: What is the impact of forward voltage differences? A: Forward voltage ranges from 2.0V to 2.4V across all parts. Circuits designed for 2.4V operation will function with lower forward voltage parts; however, current-limiting resistor values may require recalculation to maintain 20mA test current.

Q: Which substitute offers the best brightness match? A: WP710A10SECK/J3 (1600mcd) is closest to the original 2850mcd rating. OVLFR3C7 (7400mcd) provides significantly higher brightness. SSL-LX5093SRC39240 brightness is not specified.
