Substitute Part Grouping Explanation
Substitution compatibility for the 4300H5LC is determined by the following critical parameters:
Primary Compatibility Criteria:
- Lens size and form factor (5mm, T-1 3/4 round with domed top)
- Mounting type (through-hole radial configuration)
- Color specification (green diffused lens)
- Forward voltage range (1.8V to 2.1V acceptable for most circuit designs)
- Wavelength range (565nm to 575nm maintains green color perception)
Secondary Compatibility Factors:
- Millicandela rating (brightness level; 2.3mcd to 200mcd range accommodates various indication applications)
- Viewing angle (50° to 90° provides flexibility in circuit board placement)
- Current rating (2mA to 20mA test current; circuit design determines actual requirement)
- Package format (bulk, tape & reel, or cut tape; does not affect electrical function)
- RoHS3 compliance and MSL rating (environmental and handling requirements)
Substitute parts are grouped into two categories: Direct Form Factor Matches (identical T-1 3/4 package) and Functional Equivalents (5mm round diffused green LEDs with compatible electrical parameters). Parts with "Active" product status are prioritized for new applications, while "Obsolete" status parts are suitable only for legacy system maintenance.

Engineering Selection Recommendations
Tier 1 - Direct Form Factor Equivalents (Recommended for New Designs):
The Broadcom HLMP-3507 series parts (HLMP-3507, HLMP-3507-D0001, HLMP-3507-D0002) provide the closest electrical and mechanical match to the 4300H5LC. These components maintain identical T-1 3/4 form factor, green diffused lens configuration, and 565nm peak wavelength. Forward voltage increases from 1.8V to 2.1V, requiring circuit design verification for current-limiting resistor adjustment. All variants carry Active product status and ROHS3 compliance. Packaging options (bulk, tape & reel, cut tape) accommodate different manufacturing workflows.
Tier 2 - Functional Equivalents with Compatible Parameters (Suitable for Maintenance):
The Würth Elektronik 151051VS04000 (WL-TMRC series) and Everlight Electronics 1383SYGD/S530-E2 provide green or yellow-green diffused 5mm round LEDs with through-hole radial mounting. These parts operate at 2V to 2.1V forward voltage and deliver higher brightness ratings (140mcd to 200mcd) compared to the original 2.3mcd specification. Wavelength ranges from 572nm to 575nm, maintaining green color perception within acceptable tolerance. These options are suitable for applications where increased brightness or wider viewing angles improve system visibility.
Tier 3 - Specialized Configurations (Application-Specific):
The Broadcom HLMP-3507-D00B1 and HLMP-3507-D00B2 variants feature right-angle mounting configuration, suitable for circuit board indicator applications where vertical LED orientation is required. The Everlight 323-2SYGD/S530-E2 offers reduced height (6.30mm maximum) for space-constrained designs. The Everlight 336SYGSYGD/S530-E2 provides 90° viewing angle for applications requiring wide-angle visibility.
Compliance and Supply Chain Considerations:
All recommended substitute parts maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity) ratings, ensuring compatibility with standard manufacturing and storage environments. Active product status parts (Broadcom HLMP-3507 series, Würth 151051VS04000, Everlight active variants) are preferred for new production to ensure long-term supply availability. The Broadcom HLMP-3507-EF000 (Obsolete status) is suitable only for legacy system maintenance where exact electrical characteristics are critical.
Frequently Asked Questions (FAQ)
Q1: Can I directly replace the 4300H5LC with any of the listed substitute parts without circuit modification?
A: Direct replacement without modification is not recommended. The primary difference is forward voltage: the 4300H5LC operates at 1.8V, while most substitutes operate at 2.0V to 2.1V. This voltage increase requires recalculation of the current-limiting resistor in the LED circuit. The formula adjustment is: R_new = (V_supply - V_new) / I_desired. Verify your circuit design can accommodate the higher forward voltage before substitution.
Q2: What is the difference between the Broadcom HLMP-3507 variants (standard, D0001, D0002, D00B1, D00B2)?
A: All HLMP-3507 variants share identical electrical specifications (2.1V, 10mA test current, 4.2mcd, 565nm peak wavelength). Differences are in packaging and mounting configuration: standard HLMP-3507 is bulk radial; HLMP-3507-D0001 is tape & reel radial; HLMP-3507-D0002 is cut tape radial; HLMP-3507-D00B1 and D00B2 are bulk right-angle mounting. Select based on your manufacturing process (manual assembly, pick-and-place, or reel-fed equipment) and circuit board layout requirements.
Q3: Why do some substitute parts have higher millicandela ratings (140mcd to 200mcd) compared to the original 2.3mcd?
A: Millicandela rating indicates brightness intensity. Higher ratings (Würth 151051VS04000 at 140mcd, Everlight 1383SYGD/S530-E2 at 200mcd) provide increased visibility for indicator applications. These parts are suitable if your application requires brighter indication. If your circuit design relies on the original low brightness to avoid excessive power consumption or visual glare, select lower-brightness alternatives like the Broadcom HLMP-3507 series (4.2mcd) or Everlight 336SYGSYGD/S530-E2 (16mcd).
Q4: What is the significance of "Diffused" versus other lens transparency options?
A: Diffused lenses scatter light across a wider viewing angle, reducing brightness intensity in any single direction but improving visibility from off-axis positions. All listed substitutes maintain diffused lens transparency, ensuring consistent light distribution characteristics. The 4300H5LC specifies 50° viewing angle; substitutes range from 25° to 90°. Narrower angles (25° to 40°) concentrate light for direct viewing; wider angles (60° to 90°) improve visibility from multiple positions.
Q5: Are yellow-green LEDs (Everlight 1383SYGD/S530-E2, 323-2SYGD/S530-E2, 336SYGSYGD/S530-E2) acceptable replacements for green LEDs?
A: Yellow-green LEDs operate at 573nm to 575nm wavelength, compared to the 4300H5LC green at 565nm. While both appear green to human perception, yellow-green has slightly longer wavelength and may appear slightly more yellow-tinted under certain lighting conditions. These parts are acceptable if your application does not require strict color matching (e.g., generic indicator lights). If precise green color is critical (e.g., standardized status indication), select pure green alternatives like the Broadcom HLMP-3507 series (565nm) or Würth 151051VS04000 (572nm).
Q6: What does "Product Status: Not For New Designs" mean for the 4300H5LC?
A: This designation indicates the part has reached end-of-life and is no longer recommended for new product development. Manufacturers typically apply this status when transitioning to newer component generations or discontinuing product lines. The 4300H5LC remains available in limited inventory (1250 pcs) for maintenance and legacy system support. For new designs, select Active status parts such as the Broadcom HLMP-3507 series, Würth 151051VS04000, or Everlight alternatives to ensure long-term supply chain stability.
Q7: How do I determine which substitute part is best for my specific application?
A: Follow this selection process: (1) Confirm your circuit board layout accommodates the mounting type (radial standard or right-angle); (2) Verify your power supply voltage and calculate the required current-limiting resistor for the substitute's forward voltage; (3) Determine brightness requirements (compare millicandela ratings); (4) Confirm color specification (pure green vs. yellow-green); (5) Verify viewing angle matches your circuit board placement and visibility requirements; (6) Select Active status parts for new designs, Obsolete parts only for legacy maintenance.
Q8: Are all substitute parts RoHS3 compliant?
A: Yes, all listed substitute parts carry ROHS3 Compliant status, matching the 4300H5LC compliance level. This ensures compatibility with modern manufacturing standards and environmental regulations. All parts also maintain MSL Level 1 (Unlimited) moisture sensitivity rating, requiring standard storage and handling practices without special desiccant or controlled-humidity requirements.
