HLMP3315 Equivalent & Substitute Parts

Part Overview

The HLMP3315 is a red diffused T-1 3/4 through-hole LED manufactured by onsemi, designed for red indication applications. It features a 5mm lens with diffused optics, forward voltage of 2.2V at 10mA test current, and a peak wavelength of 635nm. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HLMP3315 is determined by the following critical parameters:

• Lens Size & Type: 5mm T-1 3/4 through-hole radial package
• Color & Optics: Red diffused lens
• Electrical Characteristics: Forward voltage range 2.0V–2.2V, test current 10mA–20mA
• Optical Performance: Peak wavelength 623nm–635nm, millicandela rating 18mcd–25mcd, viewing angle 30°–36°
• Compliance & Status: Active product status preferred; RoHS3 compliance and REACH compliance status

Substitute parts are grouped into two categories:

Parametric Equivalents (Diffused Lens): Parts with diffused lens transparency matching the original specification—LTL-4223. These provide the closest functional replacement.

Functional Alternatives (Clear Lens): Parts with clear lens transparency—4302H1-5V, 4302H1-12V, LTL-4214, SSL-LX5093HT, WP7113IT. These maintain the same mounting, color, and wavelength range but differ in lens transparency and optical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LTL-4223 (Lite-On Inc.) is the recommended parametric equivalent. It maintains diffused lens transparency, operates at 2V forward voltage with 10mA test current, and delivers 19mcd brightness at 635nm peak wavelength. The part is active, RoHS3 compliant, and dimensionally compatible at 8.60mm height.

Voltage-Dependent Alternatives: 4302H1-5V and 4302H1-12V are suitable only when circuit design requires 5V or 12V operation respectively. Both are active, RoHS3 compliant, but deliver lower brightness (8mcd) and wider viewing angle (60°) compared to the original specification.

Clear Lens Alternatives: LTL-4214, SSL-LX5093HT, and WP7113IT are functional alternatives when lens transparency change is acceptable. All are active and RoHS3 compliant. SSL-LX5093HT and WP7113IT offer higher brightness (25mcd and 100mcd respectively) but require higher test current (20mA). LTL-4214 maintains 10mA operation but features narrower viewing angle (16°).

Compliance Considerations: All recommended substitutes are RoHS3 compliant and REACH unaffected, suitable for applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can LTL-4223 directly replace HLMP3315 in existing designs?

A: Yes. LTL-4223 is a parametric equivalent with matching lens transparency (diffused), compatible forward voltage (2V vs. 2.2V), identical test current (10mA), and equivalent brightness (19mcd vs. 18mcd). The 0.29mm height difference (8.60mm vs. 8.89mm) is within typical PCB tolerance. No circuit modification is required.

Q: What is the difference between diffused and clear lens options?

A: Diffused lenses scatter light over a wider area with softer appearance, while clear lenses produce more focused, brighter output. The HLMP3315 uses diffused optics. LTL-4223 maintains this characteristic. Clear lens alternatives (LTL-4214, SSL-LX5093HT, WP7113IT) produce sharper light patterns and higher brightness but alter the visual appearance of the indication.

Q: Why do 4302H1-5V and 4302H1-12V have lower brightness ratings?

A: These parts are designed for direct connection to 5V and 12V supplies without series resistors, requiring internal current-limiting structures that reduce light output. They are suitable only when circuit topology requires higher supply voltages.

Q: Are all substitutes through-hole radial packages?

A: Yes. All listed substitutes maintain the T-1 3/4 (5mm) through-hole radial package configuration, ensuring mechanical compatibility with existing PCB layouts.

Q: What compliance certifications apply to these substitutes?

A: All active substitutes are RoHS3 compliant and REACH unaffected. LTL-4223 is REACH affected; verify compliance requirements for your application.
