Key Parameters

Substitute Part Grouping Explanation

Substitution for the HLMPM201 is determined by strict alignment of the following critical parameters:

• Red color specification (wavelength peak 635nm)
• Forward voltage of 2.2V at 20mA test current
• 4mm round lens configuration with flat top geometry
• 3.99mm lens diameter
• Through-hole radial mounting package
• 7 millicandela brightness rating
• 135° viewing angle
• Maximum height of 6.24mm

Only components matching all specified electrical and mechanical parameters qualify as direct substitutes. The obsolete status of the HLMPM201 necessitates identification of functionally equivalent alternatives that maintain identical performance characteristics within the stated tolerances.

Parameter Comparison

Engineering Selection Recommendations

The HLMPM201 is classified as obsolete. Selection of equivalent components must prioritize:

• Compliance with REACH regulations (REACH Unaffected status maintained)
• Moisture sensitivity level MSL 1 (Unlimited) for unrestricted storage and handling
• Electrical classification under ECCN EAR99 for export compliance
• HTSUS code 8541.41.0000 for tariff and trade documentation

Direct parametric equivalents maintain identical electrical performance, mechanical fit, and regulatory compliance. Component selection should verify current inventory availability and lead time requirements for production planning.

Frequently Asked Questions (FAQ)

Q: What makes a component a valid substitute for the HLMPM201?

A: A substitute must match all specified parameters: red color, 2.2V forward voltage, 20mA test current, 7mcd brightness, 135° viewing angle, 635nm peak wavelength, 4mm round flat-top lens, 3.99mm lens diameter, through-hole radial mounting, and 6.24mm maximum height.

Q: Why is the HLMPM201 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Equivalent alternatives must be sourced to maintain design continuity and production support.

Q: Can I substitute this LED with a different brightness level?

A: No. The 7 millicandela rating is a critical parameter. Substitutes must maintain this exact brightness specification to ensure proper circuit operation and visual indication performance.

Q: Are there mechanical compatibility concerns with through-hole mounting?

A: The radial package with 6.24mm maximum height and 3.99mm lens diameter are fixed mechanical constraints. Any substitute must maintain these dimensions for PCB footprint compatibility and mechanical clearance.

Q: What compliance certifications apply to this component?

A: The HLMPM201 maintains REACH Unaffected status and is classified under ECCN EAR99. Equivalent substitutes must preserve these regulatory designations.

Q: How does the 135° viewing angle affect substitution?

A: The 135° viewing angle defines the light distribution pattern. Substitutes must maintain this specification to ensure consistent visibility across the intended application range.
