MR30519MP5 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The MR30519MP5 is a 5mm red diffused LED circuit board indicator manufactured by onsemi, rated for 12V operation at 13mA with a 2mcd brightness rating. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

The MR30519MP5 features a through-hole T-1 3/4 form factor with a round domed top lens, designed for standard circuit board indicator applications. Due to its obsolete status, active equivalent parts from current manufacturers are required to maintain design continuity and ensure long-term component availability.

Substitute Part Grouping Explanation

Substitution for the MR30519MP5 is determined by the following critical parameters:

Primary Matching Criteria:

Color: Red
Lens Type: Diffused, Tinted
Lens Style: Round with Domed Top
Lens Size: 5mm, T-1 3/4
Mounting Type: Through Hole
Configuration: Single

Secondary Compatibility Factors:

Voltage Rating: The MR30519MP5 operates at 12V. Substitute parts with different forward voltage ratings (1.9V, 5V) require circuit design adjustment through series resistor modification
Current Rating: Test current of 10mA for substitute parts is compatible with the 13mA original specification
Millicandela Rating: Brightness variations (2.1mcd to 6.3mcd) are acceptable within indicator applications, provided circuit design accommodates the forward voltage difference

Active Substitute Parts: All substitute parts listed are from active manufacturers (Dialight, Broadcom Limited) with ROHS3 compliance and current production status, addressing the obsolescence of the original MR30519MP5.

Engineering Selection Recommendations

For RoHS3 Compliant Designs: HLMP-3301-D0000, HLMP-3301-D0001, HLMP-3301-D0002, and HLMP-3600 are all ROHS3 compliant active parts suitable for new designs requiring environmental compliance. These parts replace the non-compliant MR30519MP5.

For Brightness-Matched Substitution: HLMP-3301-D0000 and HLMP-3600 provide the closest millicandela match (2.1mcd) to the original MR30519MP5 (2mcd), minimizing visual brightness differences in indicator applications.

For Voltage Compatibility:

HLMP-3600 operates at 5V forward voltage and is suitable for 5V circuit designs
HLMP-3301 series parts operate at 1.9V forward voltage and require series resistor adjustment for 12V applications
5219240F voltage rating is not specified; forward voltage must be verified before circuit integration

For Packaging Flexibility: Broadcom HLMP-3301 variants are available in multiple packaging options (Bulk, Tape & Reel, Cut Tape), providing procurement flexibility. Dialight 5219240F is available in Bulk packaging.

For High-Volume Procurement: HLMP-3301-F00DD offers the highest inventory availability (43,381 pcs) with 5.4mcd brightness and active product status, supporting sustained production requirements.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3301 series parts directly replace MR30519MP5 without circuit modification?

A: No. The HLMP-3301 series operates at 1.9V forward voltage compared to the MR30519MP5's 12V rating. Circuit design must be modified to accommodate the lower forward voltage through series resistor adjustment. The mechanical form factor (5mm T-1 3/4 through-hole) is compatible.

Q: What is the brightness difference between MR30519MP5 and substitute parts?

A: HLMP-3301-D0000 and HLMP-3600 provide 2.1mcd, closely matching the original 2mcd. HLMP-3301 and HLMP-3301-F0002 provide 5.4mcd (2.7x brighter), and 5219240F provides 6.3mcd (3.15x brighter). Brightness selection depends on application requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original MR30519MP5 is RoHS non-compliant, making these substitutes necessary for designs requiring environmental compliance.

Q: What packaging options are available for the HLMP-3301 series?

A: HLMP-3301 variants are available in Bulk, Tape & Reel (TR), and Cut Tape (CT) packaging. Packaging selection depends on assembly process requirements and procurement volume.

Q: Can 5219240F be used as a direct mechanical replacement?

A: Yes. The 5219240F shares the same 5mm T-1 3/4 through-hole form factor and diffused red lens style. However, forward voltage is not specified in available data; verification is required before circuit integration.

Q: Which substitute part has the best long-term availability?

A: HLMP-3301-F00DD (Broadcom Limited) has the highest current inventory (43,381 pcs) and active product status, supporting sustained procurement and long-term design support.
