Substitute Part Grouping Explanation

Substitute parts for the HLMP3301NL are identified through parametric equivalence based on the following critical specifications:

Electrical Parameters: Forward voltage (2.2V typical), test current (10mA), and millicandela rating (7mcd) must match exactly to ensure proper circuit operation and brightness consistency.

Optical Parameters: Color (red), lens transparency (diffused), wavelength peak (635nm), and viewing angle (65°) determine functional interchangeability in indication applications.

Mechanical Parameters: Lens size (5mm T-1 3/4), mounting type (through hole), package configuration (radial), and maximum height (8.89mm) ensure physical compatibility with PCB layouts and mechanical assemblies.

Compliance Parameters: RoHS3 compliance and MSL Level 1 rating are maintained across all substitute parts to preserve regulatory and environmental specifications.

The HLMP3301 from onsemi is identified as a parametric equivalent based on matching all electrical, optical, and mechanical parameters, despite its obsolete product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The HLMP3301NL from Everlight Electronics Co Ltd is the recommended primary choice. This part maintains active product status, ensuring long-term availability and supply chain stability. It carries ROHS3 compliance certification and MSL Level 1 rating, meeting current regulatory requirements for industrial and consumer applications.

Substitute Selection: The HLMP3301 from onsemi is a parametric equivalent with identical electrical, optical, and mechanical specifications. However, this part carries obsolete product status, indicating discontinued manufacturing and limited inventory availability (787 units). Selection of this substitute should be limited to applications where existing inventory can be confirmed and long-term supply is not required.

Compliance Consideration: Both parts maintain equivalent environmental and regulatory compliance through ROHS3 and MSL Level 1 certifications, ensuring interchangeability from a compliance perspective.

Inventory Availability: The HLMP3301NL offers superior supply chain reliability with 1080 units in new original stock compared to the onsemi substitute with 787 units.

Frequently Asked Questions (FAQ)

Q: What parameters determine if a part can substitute for the HLMP3301NL?

A: Substitution is determined by matching forward voltage (2.2V), test current (10mA), millicandela rating (7mcd), color (red), lens transparency (diffused), wavelength peak (635nm), viewing angle (65°), lens size (5mm T-1 3/4), mounting type (through hole), package configuration (radial), and maximum height (8.89mm). All parameters must match exactly for functional equivalence.

Q: Why is the onsemi HLMP3301 listed as obsolete?

A: The onsemi HLMP3301 carries obsolete product status, indicating the manufacturer has discontinued production. This designation reflects the part's position in its product lifecycle and does not affect its electrical or mechanical compatibility with the HLMP3301NL.

Q: Are there mechanical compatibility concerns when substituting the HLMP3301?

A: No. Both the HLMP3301NL and HLMP3301 share identical mechanical specifications: 5mm T-1 3/4 lens size, radial package configuration, through-hole mounting type, and 8.89mm maximum height. PCB layouts and mechanical assemblies designed for the HLMP3301NL will accommodate the substitute without modification.

Q: Do compliance certifications differ between the main part and substitute?

A: Both parts maintain equivalent compliance status. The HLMP3301NL carries ROHS3 compliance, while the onsemi HLMP3301 is REACH unaffected. Both maintain MSL Level 1 rating, indicating no moisture sensitivity constraints during storage or handling.

Q: What is the viewing angle specification and how does it affect application selection?

A: Both parts specify a 65° viewing angle, defining the cone of visibility for the red indication light. This parameter is identical across the main part and substitute, ensuring consistent optical performance in indication applications.

Q: Should supply chain considerations influence part selection?

A: Yes. The HLMP3301NL from Everlight maintains active product status with higher inventory availability (1080 units), providing superior long-term supply chain reliability compared to the obsolete onsemi substitute (787 units). For applications requiring sustained production or future component replenishment, the HLMP3301NL is the preferred selection.
