Substitute Part Grouping Explanation

Substitute parts for the 5SRC are grouped into two categories based on parametric alignment with the original specification:

Parametric Equivalent (Highest Compatibility): The 5SRC-F from Bivar Inc. maintains identical electrical and optical characteristics: 1.7V forward voltage, 60mcd brightness, 35° viewing angle, 645nm peak wavelength, and clear lens in T-1 3/4 form factor. This part differs only in product status (Active vs. Obsolete) and packaging format (Bulk vs. original). Height specification is 8.60mm versus 8.50mm maximum, representing a negligible 0.10mm variance within typical manufacturing tolerances.

Similar Substitutes (Functional Alternatives): Additional substitutes from Bivar Inc., Everlight Electronics, and Broadcom Limited share the core red color, clear lens, T-1 3/4 form factor, and through-hole mounting. These alternatives differ in forward voltage (1.9V to 2.1V), brightness rating (2mcd to 18150mcd), and viewing angle (6° to 45°). Selection depends on circuit voltage tolerance and application brightness requirements.

Key Parameters Determining Substitution:

Color: Red (non-negotiable)
Lens Transparency: Clear (non-negotiable)
Lens Size: 5mm, T-1 3/4 (non-negotiable)
Mounting Type: Through Hole (non-negotiable)
Forward Voltage: 1.7V nominal (±0.2V acceptable range)

Engineering Selection Recommendations

First Priority: Bivar Inc. 5SRC-F

The 5SRC-F is the direct parametric equivalent to the obsolete 5SRC. It maintains identical electrical specifications (1.7V forward voltage), optical output (60mcd, 35° viewing angle, 645nm peak wavelength), and mechanical form factor (T-1 3/4 clear lens, through-hole radial package). The 5SRC-F carries Active product status and ROHS3 compliance certification. Height specification variance of 0.10mm is within standard manufacturing tolerance and does not affect PCB assembly compatibility. This part is recommended for direct substitution without circuit modification.

Second Priority: Broadcom Limited HLMP-EG08 Series

The HLMP-EG08 series (variants VY000, WZ000, WZ0DD, X1000, Y2000, YZ000) provides functional substitution with forward voltage of 1.9V, representing a 0.2V increase from the 5SRC specification. All variants maintain the T-1 3/4 clear lens form factor and through-hole mounting. These parts are Active status with ROHS3 compliance and REACH Unaffected designation. Brightness ratings range from 8100mcd to 18150mcd, significantly exceeding the 60mcd original specification. Viewing angle is 8° versus 35° original, indicating a narrower beam. Circuit voltage tolerance must accommodate 1.9V operation. Selection among HLMP-EG08 variants depends on brightness requirement: WZ000 and WZ0DD (10750mcd) provide moderate brightness increase; Y2000 and YZ000 (18150mcd and 12650mcd) provide higher brightness for applications requiring enhanced visibility.

Third Priority: Everlight Electronics 383-2SDRC/S530-A4 and 383-2SURC/S530-A6

Everlight parts provide functional alternatives with 2.0V forward voltage and clear lens in 5mm form factor. The 383-2SDRC/S530-A4 delivers 2780mcd brightness with 6° viewing angle; the 383-2SURC/S530-A6 delivers 6300mcd with 6° viewing angle. Both are Active status. Forward voltage increase to 2.0V requires circuit verification. Narrow 6° viewing angle differs significantly from 35° original specification and may not suit applications requiring wide visibility range.

Alternative: Bivar Inc. 5RD

The 5RD is an Active product from the same manufacturer with identical mechanical form factor. However, it features diffused lens (not clear), 2.1V forward voltage, and only 2mcd brightness. This part is suitable only for applications where diffused appearance is acceptable and brightness reduction is tolerable.

Frequently Asked Questions (FAQ)

Q: Can the 5SRC-F directly replace the obsolete 5SRC without any circuit changes?

A: Yes. The 5SRC-F maintains identical forward voltage (1.7V), brightness (60mcd), viewing angle (35°), and wavelength (645nm) specifications. The 0.10mm height difference (8.60mm vs. 8.50mm) is within standard manufacturing tolerance and does not affect PCB assembly. No circuit modification is required.

Q: What is the voltage tolerance when substituting with HLMP-EG08 series parts?

A: HLMP-EG08 variants operate at 1.9V forward voltage, which is 0.2V higher than the 5SRC specification of 1.7V. The circuit must be designed to tolerate this voltage increase. If the original circuit was designed with tight voltage margins, verification testing is necessary to confirm proper operation at 1.9V.

Q: Why do some substitutes have significantly higher brightness ratings than the original 5SRC?

A: The 5SRC operates at 60mcd brightness. Broadcom HLMP-EG08 variants range from 8100mcd to 18150mcd. Higher brightness results from improved LED chip efficiency and different optical design. If the application requires the original 60mcd brightness level, the higher-brightness alternatives may cause excessive illumination. Circuit design must account for brightness differences through resistor adjustment or PWM dimming if necessary.

Q: What is the difference between HLMP-EG08-WZ000 and HLMP-EG08-WZ0DD?

A: Both parts are electrically and optically identical (1.9V, 10750mcd, 8° viewing angle, 635nm wavelength). The difference is packaging: WZ000 is supplied in Bulk format, while WZ0DD is supplied in Tape & Box (TB) format. Selection depends on assembly process requirements. Bulk packaging is suitable for manual or loose component handling; Tape & Box format is optimized for automated pick-and-place assembly equipment.

Q: Can the 5RD (diffused red lens) be used as a substitute for the 5SRC (clear lens)?

A: The 5RD is mechanically compatible but functionally different. It features a diffused red lens instead of clear lens, resulting in different light transmission and appearance characteristics. The 5RD also operates at 2.1V forward voltage and delivers only 2mcd brightness compared to 60mcd. Substitution is only appropriate if the application specifically requires diffused appearance and can tolerate the lower brightness and higher voltage.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts can be stored at room temperature and humidity without special desiccant packaging or time-limited shelf life constraints. This applies to all listed substitutes and the original 5SRC.

Q: Are all substitute parts RoHS3 compliant?

A: The 5SRC-F and all Broadcom HLMP-EG08 variants carry explicit ROHS3 Compliant certification. The Everlight 383-2SDRC/S530-A4 and 383-2SURC/S530-A6 parts do not list RoHS status in the provided specifications. The original 5SRC does not list RoHS status. If RoHS3 compliance is a requirement, the 5SRC-F or Broadcom HLMP-EG08 series are confirmed compliant options.

Q: What is the viewing angle significance when selecting a substitute?

A: Viewing angle determines the cone of light visibility. The 5SRC has a 35° viewing angle, providing wide visibility across a broad area. Broadcom HLMP-EG08 variants have 8° viewing angle, creating a narrow, focused beam. Everlight parts have 6° viewing angle. If the application requires wide-angle visibility (such as panel-mounted indicators visible from multiple angles), the narrow-angle substitutes may not be suitable. If the application requires focused, directional indication, narrow-angle parts are preferable.

Q: Can I use the Everlight 383-2SURC/S530-A6 in place of the 5SRC?

A: Mechanical compatibility exists (5mm T-1 3/4 clear lens, through-hole mounting). However, electrical and optical differences must be evaluated: forward voltage increases from 1.7V to 2.0V, brightness increases from 60mcd to 6300mcd, and viewing angle narrows from 35° to 6°. Circuit voltage tolerance and brightness requirements must be verified before substitution.
