Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMPD1019MP6 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Color: Red
• Configuration: Single
• Current Rating: 20mA
• Mounting Type: Through Hole, Right Angle
• Lens Type: Diffused
• Lens Size: 5mm form factor

Allowable Variation Parameters:

• Voltage Rating: Forward voltage may vary within typical LED operating ranges
• Millicandela Rating: Brightness output may differ based on lens design and material composition
• Viewing Angle: Optical characteristics may vary with lens geometry
• Product Status: Active parts are preferred for long-term availability

The substitute part 5505105F from Dialight meets all mandatory matching criteria while maintaining functional equivalence in circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

The 5505105F from Dialight is a functional equivalent for the obsolete HLMPD1019MP6. Both components share identical mounting configuration, current rating, and color specification. The Dialight part offers the advantage of active product status, ensuring continued availability and supply chain support.

The 5505105F carries ROHS3 compliance certification, providing environmental regulatory alignment for new designs. Both parts maintain REACH Unaffected status and EAR99 export classification.

Forward voltage differs by 0.3V (1.8V vs. 2.1V), requiring circuit verification to confirm compatibility with existing current-limiting resistor networks. Brightness output of the substitute is lower at 34mcd compared to 70mcd, and viewing angle is reduced from 65° to 50°. These optical differences must be evaluated against application requirements for indicator visibility and angular coverage.

Frequently Asked Questions (FAQ)

Q: Can the 5505105F directly replace the HLMPD1019MP6 without circuit modification?

A: Both parts share identical mounting type, current rating, and color specification. However, the forward voltage difference (1.8V vs. 2.1V) requires verification of the current-limiting resistor value to ensure proper LED operation and brightness.

Q: What are the key differences between these two parts?

A: The primary differences are forward voltage (0.3V higher for the substitute), brightness output (34mcd vs. 70mcd), and viewing angle (50° vs. 65°). The substitute offers active product status and ROHS3 compliance.

Q: Is the lower brightness of the 5505105F acceptable?

A: Acceptability depends on application requirements. The 34mcd output of the substitute must be evaluated against the original 70mcd specification for the specific indicator function and visibility requirements.

Q: Are there any compliance or regulatory concerns with substitution?

A: Both parts maintain REACH Unaffected status and EAR99 classification. The substitute provides ROHS3 compliance, which may be advantageous for new designs subject to environmental regulations.

Q: What is the impact of the reduced viewing angle?

A: The substitute provides a 50° viewing angle compared to the original 65°. This narrower angle may affect indicator visibility from off-axis positions and should be evaluated for the specific mounting orientation and viewing requirements of the application.
