Substitute Part Grouping Explanation

Substitution of the HLMP47409MP7 is determined by the following critical parameters:

Primary Compatibility Criteria:

Color: Green (565nm peak wavelength)
Lens Type: Diffused, Tinted
Lens Size: 5mm, T-1 3/4
Mounting Type: Through Hole, Right Angle
Voltage Rating: 1.9V to 2.1V (low-voltage operation)
Current Rating: 2mA to 10mA (low-power indicator range)

Substitution Logic: Substitute parts must maintain the same physical form factor (5mm T-1 3/4 through-hole right-angle configuration) and operate within compatible voltage and current ranges. The HLMP47409MP7 operates at the lowest voltage tier (1.9V, 2mA), making it suitable for replacement by parts rated at 2.1V with 10mA test current, as these represent the same product family with enhanced specifications. Parts operating at significantly higher voltages (5V, 12V) or with substantially different current ratings require circuit-level design changes and are listed for reference only.

Engineering Selection Recommendations

Tier 1 - Direct Substitutes (Recommended): HLMP-3507-D00B2 and HLMP-3507-D00B1 are the primary substitutes for the HLMP47409MP7. Both maintain the right-angle through-hole mounting configuration, operate at 2.1V (compatible with 1.9V circuits with minor voltage tolerance), and deliver 4.2mcd brightness. These parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating. The HLMP-3507-D00B2 is available in bulk packaging with 1460 units in stock, while HLMP-3507-D00B1 offers 1225 units. Both are suitable for direct PCB replacement without circuit modification.

Tier 2 - Compatible Substitutes (Voltage Dependent): HLMP-3507, HLMP-3507-D0001, and HLMP-3507-D0002 are functionally equivalent but feature standard radial mounting rather than right-angle configuration. These require PCB layout modification. HLMP-3507-EF000 is obsolete and not recommended for new designs. HLMP-3680 operates at 5V and requires circuit redesign for voltage compatibility.

Tier 3 - Alternative Manufacturers: 151051VS04000 (Würth Elektronik) and 4302H5-5V (VCC) provide green LED indicators with similar form factors but different electrical specifications. The Würth part operates at 2.1V with 20mA test current and delivers significantly higher brightness (140mcd), suitable for applications requiring enhanced visibility. The VCC 4302H5-5V operates at 5V and requires circuit modification. The 4302H5-12V is not recommended due to incompatible voltage rating.

Compliance & Availability: All recommended substitutes maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory continuity. Active product status ensures long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3507-D00B2 be used as a direct replacement for HLMP47409MP7? A: Yes. Both parts feature right-angle through-hole mounting, green diffused lenses at 5mm T-1 3/4 form factor, and operate within compatible voltage ranges (1.9V vs. 2.1V). The HLMP-3507-D00B2 delivers higher brightness (4.2mcd vs. 2.3mcd) and operates at 10mA vs. 2mA, but these represent enhanced specifications within the same product family. No circuit modification is required.

Q: What is the difference between HLMP-3507-D00B1 and HLMP-3507-D00B2? A: Both are right-angle mounted green LEDs at 2.1V, 10mA with 4.2mcd brightness. HLMP-3507-D00B1 specifies diffused, tinted lens type with 60° viewing angle, while HLMP-3507-D00B2 specifies diffused lens type without viewing angle specification. Both are suitable substitutes; selection depends on lens tint preference and viewing angle requirements.

Q: Why are HLMP-3507 variants listed if they use radial mounting instead of right-angle? A: HLMP-3507 variants (standard, D0001, D0002, EF000) are electrically equivalent but require PCB layout modification due to radial mounting orientation. They are listed as secondary options for designs where PCB redesign is feasible. For direct replacement without layout changes, use HLMP-3507-D00B2 or HLMP-3507-D00B1.

Q: Can 151051VS04000 from Würth Elektronik replace HLMP47409MP7? A: Functionally yes, with design considerations. The Würth part operates at 2.1V (compatible) but features 20mA test current and 140mcd brightness—significantly higher than the original 2mA, 2.3mcd specification. This part is suitable for applications requiring enhanced brightness but may require current-limiting resistor adjustment in the circuit.

Q: What is the voltage compatibility between 1.9V and 2.1V rated LEDs? A: The 0.2V difference is within typical circuit tolerance for indicator LED applications. Circuits designed for 1.9V operation will function with 2.1V rated parts. However, verify that the power supply and current-limiting resistor design accommodate the slightly higher forward voltage without exceeding maximum circuit current limits.

Q: Are 4302H5-5V and 4302H5-12V suitable substitutes? A: 4302H5-5V requires circuit redesign due to 5V operation versus the original 1.9V specification. 4302H5-12V is not suitable due to incompatible 12V rating. Both are listed for reference in applications where voltage conversion is implemented, but they are not direct replacements.

Q: What packaging options are available for substitute parts? A: HLMP-3507-D00B2 and HLMP-3507-D00B1 are supplied in bulk packaging. HLMP-3507-D0001 is available in tape & reel format (952 units), and HLMP-3507-D0002 is supplied in cut tape format (1275 units). Packaging selection depends on production volume and assembly equipment compatibility.

Q: Do all substitute parts maintain RoHS3 compliance? A: Yes. All listed substitute parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), ensuring regulatory continuity and environmental compliance equivalent to the original HLMP47409MP7.
