HLMP1320 Equivalent & Substitute Parts Reference

Part Overview

The HLMP1320 is an active red LED indication component manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This 3mm T-1 form factor LED operates at 2V forward voltage and delivers 12mcd luminous intensity with a clear lens and 45° viewing angle. The component is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and consumer electronics applications. Substitute parts are identified to address inventory availability, lead time constraints, or specific performance requirements while maintaining electrical and mechanical compatibility within the allowed parameter ranges for this LED category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP1320 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Color: Red
• Lens Transparency: Clear
• Lens Size: 3mm, T-1 form factor
• Voltage - Forward (Vf) Typical: 2V
• Mounting Type: Through Hole
• Lens Style: Round with Domed Top
• Package / Case: Radial configuration
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Millicandela Rating: Substitutes may exceed the 12mcd specification
• Current - Test: Substitutes operating at lower test current (10mA vs 20mA) are acceptable
• Wavelength - Peak: Substitutes within the red spectrum range (623nm to 635nm) are acceptable
• Height (Max): Minor dimensional variations within mechanical tolerance (5.85mm to 6.30mm) are acceptable
• Moisture Sensitivity Level: MSL 1 rating maintained across all substitutes

The LTL-4222N from Lite-On Inc. qualifies as a direct substitute based on these criteria. All parameters match mandatory requirements, while allowable variations remain within acceptable engineering tolerances for red LED indication applications.

Engineering Selection Recommendations

HLMP1320 (Everlight Electronics Co Ltd): Use as primary selection when Everlight inventory is available. Active product status with 647 units in stock. ROHS3 compliant with unlimited MSL rating. Operates at specified 20mA test current with 12mcd luminous intensity.

LTL-4222N (Lite-On Inc.): Use as substitute when HLMP1320 availability is constrained. Active product status with 51,200 units in stock, providing superior lead time assurance. ROHS3 compliant with REACH affected status. Delivers higher luminous intensity (29mcd) at lower test current (10mA), reducing power consumption in equivalent circuit designs. Mechanical height is 0.45mm shorter, remaining within standard PCB layout tolerances for 3mm T-1 through-hole components.

Both parts maintain identical electrical operating parameters (2V forward voltage), optical characteristics (red color, clear lens, 45° viewing angle, 635nm peak wavelength), and mechanical form factor (3mm T-1 radial package). Selection between these parts should be based on inventory availability, supplier lead times, and power budget requirements rather than functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can LTL-4222N replace HLMP1320 in existing PCB designs without modification?

A: Yes. Both components share identical lens size (3mm T-1), mounting type (through-hole radial), forward voltage (2V), and viewing angle (45°). The LTL-4222N height of 5.85mm is 0.45mm shorter than the HLMP1320 at 6.30mm, which remains within standard mechanical tolerances for through-hole LED mounting. No PCB layout changes are required.

Q: What is the difference in brightness between these two parts?

A: The LTL-4222N delivers 29mcd compared to the HLMP1320 at 12mcd. This represents a higher luminous intensity output. Both parts operate at the same 2V forward voltage. The LTL-4222N achieves this higher intensity at a lower test current (10mA vs 20mA), resulting in reduced power consumption.

Q: Are both parts RoHS compliant?

A: Yes. Both HLMP1320 and LTL-4222N are ROHS3 compliant. The LTL-4222N additionally carries REACH affected status, which may be relevant for specific regulatory requirements in certain markets.

Q: What is the wavelength specification for these red LEDs?

A: Both parts specify a peak wavelength of 635nm, which is within the standard red LED spectrum. The LTL-4222N also lists a dominant wavelength of 623nm. Both wavelengths are acceptable for red indication applications and are visually indistinguishable in standard lighting conditions.

Q: Can I use these parts interchangeably in high-volume production?

A: Yes, provided your circuit design accommodates the allowable parameter variations. The LTL-4222N's higher luminous intensity (29mcd) and lower test current (10mA) may require circuit verification if brightness or power consumption are critical specifications. Both parts maintain identical forward voltage (2V) and form factor, supporting direct substitution at the component level.

Q: What is the moisture sensitivity rating for these components?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly processes.
