HLMP3315 Equivalent & Substitute Parts Reference

Part Overview

The HLMP3315 is an active-status red LED indicator designed for through-hole mounting applications. Manufactured by Everlight Electronics Co Ltd, this T-1 3/4 (5mm) diffused lens component operates at 2.2V forward voltage with a 10mA test current. The component delivers 18mcd luminous intensity with a 35° viewing angle and peak wavelength of 635nm. ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1) support broad industrial and commercial deployment. Substitute parts are identified to address inventory availability, voltage requirement variations, or specific application constraints while maintaining functional equivalence within the red LED indicator category.

Substitute Part Grouping Explanation

Substitute parts for the HLMP3315 are classified into two categories based on substitution criteria:

Direct Parametric Equivalents: Parts that maintain identical or near-identical electrical and mechanical parameters, enabling direct replacement without circuit modification.

Voltage-Variant Substitutes: Parts that share the same physical form factor (T-1 3/4, 5mm, through-hole, radial package) and optical characteristics (red diffused lens, 635nm peak wavelength) but operate at different forward voltages (5V or 12V). These require circuit design consideration for voltage compatibility.

Substitution Logic:

• All substitute parts maintain T-1 3/4 (5mm) lens size and through-hole radial mounting
• All substitute parts feature red diffused lens with 635nm peak wavelength
• All substitute parts are ROHS3 compliant with MSL 1 rating
• Substitution validity depends on circuit voltage supply and current-limiting design
• Millicandela rating and viewing angle variations are acceptable within the red LED indicator category when application brightness and viewing geometry permit

Engineering Selection Recommendations

HLMP3315 Primary Application: Select when circuit design specifies 2.2V forward voltage operation with 10mA test current and requires 18mcd luminous intensity at 35° viewing angle.

LTL-4223 (Lite-On Inc.) - Parametric Equivalent: This part provides the closest parametric match to HLMP3315. Forward voltage of 2V is within the low-voltage LED category, test current remains 10mA, and millicandela rating of 19mcd exceeds the main part specification. Viewing angle of 36° is functionally equivalent to 35°. Height of 8.60mm is compatible with HLMP3315 at 8.89mm. LTL-4223 carries REACH Affected status; verify compliance requirements for end application. Select when HLMP3315 inventory is unavailable and 2V operation is acceptable within circuit tolerance.

4302H1-5V (Visual Communications Company - VCC): Select for 5V circuit designs requiring red diffused T-1 3/4 through-hole LED. Test current of 10mA matches HLMP3315. Millicandela rating of 8mcd is lower; verify application brightness requirements. Viewing angle of 60° provides wider light distribution than HLMP3315. Height of 10.08mm exceeds HLMP3315; confirm PCB clearance. ROHS3 compliant with unlimited MSL. Active product status supports long-term availability.

4302H1-12V (Visual Communications Company - VCC): Select for 12V circuit designs requiring red diffused T-1 3/4 through-hole LED. Test current of 13mA exceeds HLMP3315 specification; verify current-limiting resistor design. Millicandela rating of 8mcd is lower; verify application brightness requirements. Viewing angle of 60° provides wider light distribution. Height of 10.08mm exceeds HLMP3315; confirm PCB clearance. ROHS3 compliant with unlimited MSL and REACH Unaffected status. Active product status supports long-term availability.

All substitute parts maintain active product status and ROHS3 compliance, supporting regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can HLMP3315 be directly replaced with 4302H1-5V or 4302H1-12V without circuit modification?

A: No. HLMP3315 operates at 2.2V forward voltage, while 4302H1-5V requires 5V and 4302H1-12V requires 12V. Direct substitution requires circuit redesign of the current-limiting resistor to accommodate the different forward voltage. The LED itself will not function correctly if connected to a circuit designed for 2.2V operation.

Q: What is the difference between HLMP3315 and LTL-4223?

A: Both are low-voltage red diffused T-1 3/4 through-hole LEDs with similar operating parameters. HLMP3315 operates at 2.2V with 18mcd brightness; LTL-4223 operates at 2V with 19mcd brightness. Viewing angles are 35° and 36° respectively. Physical heights differ slightly (8.89mm vs 8.60mm). LTL-4223 carries REACH Affected status. Both are suitable for direct substitution in low-voltage indicator applications where 2V operation is acceptable.

Q: Are all substitute parts physically compatible with HLMP3315 PCB footprints?

A: All substitute parts share the same T-1 3/4 (5mm) lens size, through-hole radial package configuration, and standard LED lead spacing. Physical compatibility is confirmed for PCB footprints designed for 5mm through-hole radial LEDs. Height variations (8.60mm to 10.08mm) are within standard through-hole component tolerances and do not affect footprint compatibility. Verify PCB clearance above the component if height-constrained applications exist.

Q: Which substitute part has the highest brightness?

A: LTL-4223 delivers 19mcd, which exceeds HLMP3315 at 18mcd. Both 4302H1-5V and 4302H1-12V deliver 8mcd, which is lower. Select LTL-4223 for applications requiring maximum brightness within the low-voltage red LED category.

Q: What is the viewing angle difference between HLMP3315 and substitute parts?

A: HLMP3315 provides 35° viewing angle. LTL-4223 provides 36°, which is functionally equivalent. Both 4302H1-5V and 4302H1-12V provide 60° viewing angle, offering wider light distribution. Select 60° viewing angle parts when broader light spread is required; select 35-36° parts for more focused indication.

Q: Are all parts RoHS3 compliant?

A: Yes. HLMP3315, 4302H1-5V, 4302H1-12V, and LTL-4223 are all ROHS3 compliant. All carry MSL 1 (Unlimited) moisture sensitivity rating, supporting standard storage and handling conditions.

Q: What is the REACH status difference?

A: HLMP3315 and LTL-4223 do not specify REACH status in provided data. 4302H1-5V and 4302H1-12V are REACH Unaffected. Verify REACH compliance requirements for your specific end application and regulatory jurisdiction.

Q: Can I use 4302H1-5V in a 2.2V circuit?

A: No. 4302H1-5V is designed for 5V operation. Applying 2.2V will result in insufficient forward voltage and the LED will not illuminate or will operate at very low brightness. Conversely, applying 5V to an HLMP3315 designed for 2.2V will cause excessive current and component failure.
