HLMP2350 Equivalent & Substitute Parts

Part Overview

The HLMP2350 is a red LED circuit board indicator bar manufactured by Everlight Electronics Co Ltd. This component features a single SIP configuration with a rectangle flat-top lens design, rated for 2V operation at 90mA with a peak wavelength of 635nm and 45mcd brightness output. The part is classified as obsolete, necessitating identification of active equivalent components for new designs or replacement applications. Substitute parts must maintain functional compatibility through matching electrical characteristics, mechanical form factors, and mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HLMP2350 is determined by the following critical parameters:

Electrical Compatibility: Voltage rating and current specifications must support circuit integration without requiring redesign of current-limiting resistors or power supply modifications.

Optical Characteristics: Color and wavelength peak must match the original specification to maintain visual consistency and system functionality.

Mechanical Compatibility: Configuration type (SIP or DIP), lens style (rectangle with flat top), and mounting type (through hole) must align with PCB layout and assembly processes.

Regulatory Compliance: RoHS3 compliance and moisture sensitivity level ensure environmental and manufacturing process compatibility.

The identified substitute parts maintain these core parameters while offering active product status and improved availability compared to the obsolete HLMP2350.

Parameter Comparison

Engineering Selection Recommendations

HLCP-B100 (Broadcom Limited): This substitute maintains SIP configuration and through-hole mounting identical to the HLMP2350. The component is active and ROHS3 compliant with MSL 1 rating. The wavelength peak of 645nm represents a 10nm shift from the original 635nm specification. Electrical operation differs significantly: 1.8V at 20mA versus the original 2V at 90mA. This lower current requirement reduces power dissipation and may require circuit redesign for current-limiting resistor values. Brightness output of 15mcd is reduced from the original 45mcd. Selection of this substitute is appropriate for applications where lower brightness and reduced power consumption are acceptable.

LTL-2350HR (Lite-On Inc.): This substitute maintains the original 2V voltage rating and 635nm wavelength peak, providing direct optical compatibility. The component is active and ROHS3 compliant. Configuration differs from the original: DIP format instead of SIP, which affects PCB footprint and assembly compatibility. Current rating of 20mA is substantially lower than the original 90mA specification, requiring circuit redesign. Brightness output of 8mcd is significantly reduced from 45mcd. Selection of this substitute is appropriate for applications where the DIP footprint can be accommodated and lower brightness levels are acceptable.

Both substitutes are active products with current manufacturing support and regulatory compliance. Selection between them depends on specific circuit requirements regarding voltage, current, brightness output, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the HLCP-B100 be used as a direct replacement for the HLMP2350 without circuit modifications?

A: No. The HLCP-B100 operates at 1.8V and 20mA compared to the HLMP2350's 2V and 90mA specification. Current-limiting resistor values must be recalculated for the lower current requirement. The reduced brightness output of 15mcd versus 45mcd may affect visibility in the application.

Q: What is the primary difference between the HLCP-B100 and LTL-2350HR substitutes?

A: The HLCP-B100 maintains SIP configuration matching the original HLMP2350, while the LTL-2350HR uses DIP configuration. The LTL-2350HR preserves the original 2V voltage rating and 635nm wavelength, whereas the HLCP-B100 operates at 1.8V with a 645nm wavelength. Both have significantly reduced current ratings and brightness compared to the original.

Q: Does the wavelength difference between HLMP2350 (635nm) and HLCP-B100 (645nm) affect visual appearance?

A: The 10nm wavelength difference represents a shift toward the orange end of the red spectrum. Both wavelengths are within the red LED range, but the HLCP-B100 may appear slightly more orange-tinted compared to the original component.

Q: Are both substitute parts available in the same packaging as the HLMP2350?

A: The HLMP2350 packaging is not specified in the available data. Both HLCP-B100 and LTL-2350HR are supplied in tube packaging. Verify packaging compatibility with your assembly process requirements.

Q: Which substitute part is recommended for applications requiring maximum brightness?

A: Neither substitute achieves the original HLMP2350 brightness of 45mcd. The HLCP-B100 provides 15mcd and the LTL-2350HR provides 8mcd. For applications requiring high brightness output, alternative components outside this substitute list may be necessary.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both HLCP-B100 and LTL-2350HR are ROHS3 compliant, matching the environmental compliance of the original HLMP2350.

Q: What is the moisture sensitivity level of the LTL-2350HR?

A: The moisture sensitivity level for the LTL-2350HR is not specified in the available technical data. Contact the manufacturer for this specification if MSL rating is required for your manufacturing process.
