Part Overview

The HLMP47199MP5 is a 5mm yellow circuit board indicator LED manufactured by onsemi, designed for through-hole mounting applications. This part operates at 1.9V with a 2mA test current and delivers 2.1 millicandela of luminous intensity with a 50° viewing angle. The component features a diffused, tinted lens with a round domed top in the standard T-1 3/4 package format.

The HLMP47199MP5 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems or new designs requiring compatible yellow LED indicators.

Substitute Part Grouping Explanation

Substitution compatibility for the HLMP47199MP5 is determined by the following critical parameters:

Primary Matching Criteria:

Color: Yellow
Lens Size: 5mm, T-1 3/4 package format
Mounting Type: Through Hole
Voltage Rating: 1.9V nominal
Current Rating: 2mA test current
Lens Type: Diffused, Tinted
Viewing Angle: 50°

Secondary Compatibility Factors:

Wavelength - Peak: 565nm (yellow spectrum)
Millicandela Rating: Approximately 1.8–2.1mcd
Lens Style: Round with Domed Top
Moisture Sensitivity Level: 1 (Unlimited)
RoHS Compliance: ROHS3 Compliant

Substitute parts are grouped based on matching these electrical and mechanical parameters. Parts that deviate significantly in voltage rating, current requirements, lens size, or wavelength are classified as non-equivalent and are excluded from direct substitution.

Engineering Selection Recommendations

5219321F (Dialight) provides the closest electrical match to the HLMP47199MP5. This part maintains identical voltage (1.9V) and current (2mA) specifications with equivalent millicandela output (1.8mcd vs. 2.1mcd). The 50° viewing angle matches the original specification. This part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. The primary consideration is lens diameter (4.83mm vs. 5mm nominal), which may require mechanical verification for PCB mounting hole compatibility.

HLMP-3401-E00B2 (Broadcom Limited) offers compatibility with the same 5mm T-1 3/4 package format and diffused, tinted lens type. Forward voltage is slightly elevated at 2V versus 1.9V, and test current is specified at 10mA versus 2mA. Millicandela output is higher at 5.7mcd. This part features right-angle mounting configuration, which differs from the original straight through-hole design. Active product status and ROHS3 compliance are confirmed.

HLMP-3650-C00B2 (Broadcom Limited) maintains the 5mm T-1 3/4 package and diffused, tinted lens characteristics. Forward voltage is rated at 5V with 10mA test current, representing a significant departure from the original 1.9V/2mA specification. Millicandela output is 2.2mcd, closely matching the original. Right-angle mounting configuration applies. This part is suitable only for applications where circuit design accommodates the higher voltage requirement.

All recommended substitutes carry active product status, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility with the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can 5219321F directly replace HLMP47199MP5 in existing PCB designs?

A: 5219321F is electrically compatible with matching 1.9V and 2mA specifications. The lens diameter difference (4.83mm vs. 5mm) requires verification that existing PCB mounting holes accommodate the substitute part. Mechanical fit must be confirmed before production implementation.

Q: What is the primary difference between HLMP-3401-E00B2 and HLMP-3650-C00B2?

A: The primary difference is forward voltage specification. HLMP-3401-E00B2 operates at 2V with 10mA test current, while HLMP-3650-C00B2 requires 5V with 10mA test current. Both feature right-angle mounting and higher millicandela output than the original part. Circuit design must accommodate the voltage and current requirements of the selected substitute.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the regulatory status of the original HLMP47199MP5.

Q: What does "Right Angle" mounting mean for HLMP-3401-E00B2 and HLMP-3650-C00B2?

A: Right-angle mounting indicates the LED leads are configured perpendicular to the lens axis, allowing the LED to mount parallel to the PCB surface rather than perpendicular. This configuration requires different PCB layout and hole positioning compared to standard through-hole straight mounting.

Q: Can I use HLMP-3650-C00B2 as a direct substitute if my circuit operates at 5V?

A: Yes, if your circuit design operates at 5V and can accommodate 10mA current draw, HLMP-3650-C00B2 is electrically compatible. The right-angle mounting configuration and higher millicandela output (2.2mcd) must be verified for mechanical and optical compatibility with the original application.

Q: What is the moisture sensitivity level, and why does it matter?

A: Moisture Sensitivity Level (MSL) 1 indicates unlimited moisture exposure tolerance. All substitute parts carry MSL 1 rating, meaning they do not require special moisture-controlled storage or handling procedures, matching the original part's environmental requirements.
