LED ORANGE CLEAR T-1 3/4 T/H 5UOC Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 5UOC is an orange LED indication component featuring a clear lens with 2000mcd brightness rating, designed for through-hole mounting in T-1 3/4 (5mm) form factor. This discrete radial LED operates at 1.8V forward voltage with 20mA test current and provides a 20° viewing angle. The product is classified as obsolete, necessitating identification of functionally equivalent active alternatives that maintain compatibility with existing circuit designs and mechanical mounting requirements.

Substitute Part Grouping Explanation

Substitution logic for the 5UOC is based on the following critical parameters:

Primary Matching Criteria:

Color: Orange (visual indication function)
Lens Transparency: Clear (optical transmission)
Lens Size: 5mm, T-1 3/4 (mechanical form factor)
Mounting Type: Through Hole (assembly compatibility)
Package / Case: Radial (lead configuration)

Secondary Compatibility Parameters:

Voltage - Forward (Vf): 1.8V nominal; substitutes within 1.98V–2.1V range remain compatible with standard current-limiting resistor designs
Current - Test: 20mA standard operating point
Wavelength - Peak: 605nm–625nm range defines orange spectral band
Height (Max): 8.50mm–8.91mm acceptable for mechanical clearance

Brightness Consideration: The 5UOC operates at 2000mcd. Substitute parts range from 1290mcd to 10750mcd. Selection depends on application visibility requirements; higher brightness substitutes (HLMP-EJ08-WZ000 at 10750mcd) provide enhanced visibility, while lower brightness options (HLMP-EJ30-NR0DD at 1290mcd) maintain similar light output.

Product Status Priority: Active status substitutes are preferred for long-term availability. Obsolete alternatives are listed for reference only.

Engineering Selection Recommendations

Primary Substitute: HLMP-EJ30-NR0DD (Broadcom Limited)

This component is the recommended substitute based on the following factors:

Product Status: Active with 19,741 pieces in stock, ensuring long-term availability
Compliance: RoHS3 compliant and REACH unaffected
Form Factor Compatibility: Identical T-1 3/4 (5mm) lens size and radial through-hole mounting
Electrical Compatibility: 1.98V forward voltage is within acceptable tolerance of the 5UOC's 1.8V specification; standard current-limiting resistor designs accommodate this 0.18V difference
Optical Characteristics: 1290mcd brightness and 30° viewing angle provide comparable light output and beam spread to the original 2000mcd/20° specification
Mechanical Fit: 8.91mm maximum height is acceptable for standard PCB clearance applications

Secondary Substitute: HLMP-EJ08-WZ000 (Broadcom Limited)

This alternative is suitable for applications requiring enhanced brightness:

Product Status: Active with 1,056 pieces in stock
Compliance: RoHS3 compliant and REACH unaffected
Brightness Enhancement: 10750mcd output provides significantly higher visibility compared to the original 2000mcd
Narrow Beam: 8° viewing angle concentrates light output; appropriate for directional indication applications
Electrical Compatibility: 1.98V forward voltage matches HLMP-EJ30-NR0DD

Tertiary Substitute: HLMP-EJ30-NR000 (Broadcom Limited)

This option provides identical electrical and optical specifications to HLMP-EJ30-NR0DD with bulk packaging:

Product Status: Active with 926 pieces in stock
Compliance: RoHS3 compliant and REACH unaffected
Specification Match: Identical 1290mcd, 30° viewing angle, and 1.98V forward voltage
Packaging Difference: Supplied in bulk packaging rather than cut tape

Frequently Asked Questions (FAQ)

Q: Can the HLMP-EJ30-NR0DD directly replace the 5UOC without circuit modification?

A: Yes. The 1.98V forward voltage of the HLMP-EJ30-NR0DD is compatible with standard LED current-limiting resistor designs. The 0.18V difference from the original 1.8V specification does not require resistor recalculation for typical 5V or 12V supply circuits. Verify the existing resistor value accommodates the 20mA test current specification.

Q: What is the difference between HLMP-EJ30-NR0DD and HLMP-EJ30-NR000?

A: Both parts are electrically and optically identical. The primary difference is packaging: HLMP-EJ30-NR0DD is supplied in cut tape (CT) format with 19,741 pieces available, while HLMP-EJ30-NR000 is supplied in bulk packaging with 926 pieces available. Select based on assembly process requirements.

Q: Why does the HLMP-EJ08-WZ000 have a different viewing angle (8° vs. 20°)?

A: The HLMP-EJ08-WZ000 features a narrower 8° viewing angle compared to the original 5UOC's 20° angle. This concentrates the 10750mcd output into a tighter beam pattern, suitable for applications requiring directional indication. The original 20° viewing angle is better matched by HLMP-EJ30-NR0DD at 30°.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended Broadcom Limited substitutes (HLMP-EJ30-NR0DD, HLMP-EJ08-WZ000, HLMP-EJ30-NR000) are RoHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the maximum height clearance for PCB assembly?

A: The original 5UOC specifies 8.50mm maximum height. Substitute parts HLMP-EJ30-NR0DD, HLMP-EJ08-WZ000, and HLMP-EJ30-NR000 specify 8.91mm maximum height. This 0.41mm difference is acceptable for standard PCB designs with typical component clearance specifications of 10mm or greater.

Q: Can I use a substitute with different brightness (mcd rating)?

A: Brightness selection depends on application requirements. The original 5UOC operates at 2000mcd. HLMP-EJ30-NR0DD provides 1290mcd (lower brightness), while HLMP-EJ08-WZ000 provides 10750mcd (higher brightness). Verify the application's visibility requirements before selecting a substitute with significantly different brightness.

Q: Is the 5AD (Amber) a suitable substitute?

A: No. The 5AD is amber-colored (605nm peak wavelength) rather than orange (625nm peak wavelength). Color substitution changes the visual indication function and is not recommended unless the application specifically permits amber indication instead of orange.
