Substitute Part Grouping Explanation
Substitution of the SSL-LX3044SRC/D is determined by the following critical parameters:
Primary Substitution Criteria:
- Red color specification
- Clear lens transparency
- Through-hole radial mounting configuration
- T-1 form factor (3mm lens size)
- Forward voltage compatibility (1.8V nominal)
- Test current of 20mA
- ROHS3 compliance and MSL 1 rating
Secondary Compatibility Factors:
- Millicandela rating (brightness level tolerance)
- Peak wavelength (660nm reference)
- Viewing angle (30° baseline)
- Physical height constraints
- Package format (bulk, tape & reel, or cut tape)
Substitute parts are grouped into two categories based on electrical and mechanical alignment:
Category A - Direct Electrical Equivalents (1.8V Forward Voltage): Parts matching the 1.8V forward voltage specification with clear lens and T-1 form factor. These include Bivar 3SURC-F and Broadcom HLMP-K105 series, which maintain the same operating voltage and test current parameters.
Category B - Functional Alternatives (2.0V Forward Voltage): Parts operating at 2.0V forward voltage with clear lens and T-1 form factor. These include Everlight 1224-10SURC/S530-A3 and Broadcom HLMP-Y601-J0000, which provide functional equivalence with minor voltage adjustment in circuit design.
Category C - Specialized Variants: Parts with diffused lens or reduced brightness specifications, such as Würth Elektronik 151031SS04000, which provide alternative optical characteristics while maintaining through-hole radial configuration.

Engineering Selection Recommendations
Primary Recommendation - Category A (1.8V Direct Equivalents):
The Bivar 3SURC-F provides the closest electrical match to the SSL-LX3044SRC/D, operating at identical 1.8V forward voltage with 20mA test current. This part is active, ROHS3 compliant, and maintains the T-1 form factor with clear lens specification. The 200mcd brightness rating represents a reduction from the original 600mcd specification; circuit design must accommodate this brightness differential. The 20° viewing angle is narrower than the original 30°, requiring verification of application requirements.
The Broadcom HLMP-K105 and HLMP-K105-J0002 also operate at 1.8V with matching test current. These parts are active and ROHS3 compliant. The HLMP-K105-J0002 variant in cut tape packaging offers higher inventory availability (20,739 pcs) compared to bulk packaging. Both variants feature 65mcd brightness and 45° viewing angle, with maximum height of 6.35mm. The reduced brightness requires circuit evaluation.
Secondary Recommendation - Category B (2.0V Functional Alternatives):
The Broadcom HLMP-Y601-J0000 operates at 2.0V forward voltage with 20mA test current, providing 680mcd brightness that exceeds the original specification. This part is active, ROHS3 compliant, and maintains T-1 form factor with clear lens. Circuit design must accommodate the 0.2V voltage increase. The 45° viewing angle provides wider light distribution than the original 30°.
The Broadcom HLMP-Y651-G0000 operates at 2.0V with 300mcd brightness and 45° viewing angle. This part is active and ROHS3 compliant, suitable for applications where moderate brightness increase and wider viewing angle are acceptable.
The Everlight 1224-10SURC/S530-A3 operates at 2.0V with 400mcd brightness and 20° viewing angle. This part is active and available in tape & reel packaging. RoHS status is not specified in the provided data.
Specialized Alternative - Category C (Diffused Lens):
The Würth Elektronik 151031SS04000 features a diffused red lens with 160mcd brightness, operating at 2.0V with 20mA test current. This part is active and ROHS3 compliant. The diffused lens provides different optical characteristics suitable for applications requiring light diffusion rather than focused indication. The 40° viewing angle and 5.55mm height are within acceptable mechanical constraints.
Brightness Consideration:
The SSL-LX3044SRC/D operates at 600mcd. Direct electrical equivalents (3SURC-F, HLMP-K105) provide significantly reduced brightness (200mcd and 65mcd respectively). Applications sensitive to brightness levels require either acceptance of reduced output or selection of higher-brightness alternatives (HLMP-Y601-J0000 at 680mcd or HLMP-Y651-G0000 at 300mcd), which operate at 2.0V and require circuit modification.
Compliance and Availability:
All recommended substitutes are ROHS3 compliant with MSL 1 rating, matching the original part's environmental specifications. Broadcom parts demonstrate highest inventory availability, with HLMP-K105-J0002 offering 20,739 pcs in cut tape format.
Frequently Asked Questions (FAQ)
Q: Can the 3SURC-F directly replace the SSL-LX3044SRC/D without circuit modification?
A: The 3SURC-F matches the 1.8V forward voltage and 20mA test current, enabling direct electrical substitution. However, the brightness reduction from 600mcd to 200mcd requires verification that the application tolerates this output level. Physical height increases from 4.60mm to 5.30mm; verify PCB layout clearance.
Q: What is the primary difference between HLMP-K105 and HLMP-K105-J0002?
A: Both parts are electrically and mechanically identical, operating at 1.8V with 65mcd brightness and 45° viewing angle. The difference is packaging format: HLMP-K105 is supplied in bulk, while HLMP-K105-J0002 is supplied in cut tape (CT). The cut tape variant offers significantly higher inventory availability (20,739 pcs vs. 2,300 pcs).
Q: Why do some substitutes operate at 2.0V instead of 1.8V?
A: The HLMP-Y601-J0000, HLMP-Y651-G0000, Everlight 1224-10SURC/S530-A3, and Würth Elektronik 151031SS04000 are designed with higher forward voltage specifications. These parts require circuit modification to accommodate the 0.2V voltage increase. This is acceptable in many applications but must be evaluated for each specific design.
Q: Is the Würth Elektronik 151031SS04000 suitable as a direct replacement?
A: The 151031SS04000 features a diffused red lens rather than clear lens, fundamentally altering the optical output characteristics. This part is suitable only for applications where diffused light output is acceptable or preferred. The 2.0V forward voltage requires circuit modification.
Q: What is the significance of the 30° viewing angle in the original part?
A: The SSL-LX3044SRC/D specifies 30° viewing angle, defining the cone of light distribution. Most substitute parts offer 45° viewing angle (wider distribution) or 20° viewing angle (narrower distribution). Applications requiring specific viewing angle characteristics must verify compatibility with the selected substitute.
Q: Can HLMP-K155 or HLMP-K155-D0002 replace the SSL-LX3044SRC/D?
A: These parts operate at 1.7V forward voltage with only 1mA test current and 3mcd brightness. While electrically similar, the dramatically reduced brightness (3mcd vs. 600mcd) and test current make these parts unsuitable for direct replacement in standard indication applications. These parts are designed for low-power indicator applications only.
Q: What packaging options are available for substitute parts?
A: Substitute parts are available in multiple packaging formats: bulk (loose components), tape & reel (TR) for automated assembly, and cut tape (CT) for semi-automated or manual assembly. Selection depends on manufacturing process requirements. Broadcom HLMP-K105-J0002 in cut tape format offers the highest inventory availability.
Q: Are all substitute parts ROHS3 compliant?
A: All recommended substitutes except the Everlight 1224-10SURC/S530-A3 explicitly specify ROHS3 compliance. The Everlight part's RoHS status is not provided in the available data. Verify compliance requirements for your specific application before selection.
Q: What is the impact of height differences on PCB layout?
A: The SSL-LX3044SRC/D has maximum height of 4.60mm. Substitute parts range from 5.20mm to 6.35mm. These differences may affect PCB clearance, component spacing, and mechanical assembly. Verify that selected substitutes fit within existing mechanical constraints.
Q: Which substitute offers the closest brightness match to the original 600mcd?
A: The Broadcom HLMP-Y601-J0000 provides 680mcd brightness, the closest match to the original 600mcd specification. This part operates at 2.0V forward voltage and requires circuit modification. The Everlight 1224-10SURC/S530-A3 provides 400mcd at 2.0V as an intermediate option.
