Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5SURC are evaluated based on the following electrical and mechanical compatibility criteria:

Primary Substitution Parameters:

• Lens size: 5mm, T-1 3/4 package
• Mounting type: Through Hole, Radial configuration
• Color: Red
• Operating current: 20mA test condition
• Forward voltage range: 1.7V to 2.2V (acceptable operational window)
• Lens transparency: Clear (with limited tolerance for diffused variants in non-critical applications)

Compatible Substitutes by Compatibility Level:

Parts meeting all primary electrical and mechanical parameters: MV8102 (onsemi), MV8141 (Fairchild Semiconductor), and OVLLR8C7 (TT Electronics/Optek Technology).

Parts with modified lens transparency but equivalent electrical characteristics: 5RD (Bivar Inc.).

Parts with adjusted brightness specifications: MV3750 (onsemi).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MV8141 (Fairchild Semiconductor)

The MV8141 provides direct electrical compatibility with the 5SURC, matching the 1.7V forward voltage and 370mcd brightness specification. This part carries active product status and RoHS3 compliance, ensuring continued availability and regulatory conformance. With 6,805 units in stock, supply continuity is established. The 40° viewing angle approximates the original 35° specification, making this the preferred drop-in replacement for most applications.

Secondary Recommendation: MV8102 (onsemi)

The MV8102 offers identical electrical characteristics to the 5SURC with 1.7V forward voltage and 370mcd rating. This part meets REACH unaffected status but carries obsolete product designation. Inventory availability is 1,077 units, supporting near-term production requirements.

Alternative for Wide-Angle Applications: OVLLR8C7 (TT Electronics/Optek Technology)

The OVLLR8C7 is suitable for applications requiring increased viewing angle and brightness. With 900mcd and 100° viewing angle, this part is recommended only when application requirements allow higher luminous intensity and wider angular distribution. Active product status and RoHS3 compliance support long-term use. Exceptionally large inventory (90,624 units) ensures sustained availability.

Alternative for Same-Manufacturer Continuity: 5RD (Bivar Inc.)

The 5RD maintains Bivar Inc. manufacturing lineage with active product status. The diffused lens transparency and reduced 2mcd brightness make this suitable only for applications where brightness reduction is acceptable. This option preserves design continuity within the Bivar product family.

Frequently Asked Questions (FAQ)

Q: Can MV8141 be used as a direct replacement for 5SURC?

A: Yes. Both parts operate at 1.7V forward voltage with 370mcd brightness in T-1 3/4 through-hole packages. Mechanical and electrical compatibility is established. MV8141 carries active product status, whereas 5SURC is obsolete, making MV8141 the recommended choice for new designs.

Q: What is the brightness difference between the substitutes?

A: The 5SURC operates at 500mcd. MV8141 and MV8102 both provide 370mcd (74% of original). OVLLR8C7 provides 900mcd (180% of original). 5RD provides only 2mcd (0.4% of original). Selection depends on application brightness requirements.

Q: How do forward voltage differences affect circuit design?

A: All substitutes operate between 1.7V and 2.2V, within a 0.5V window. Series resistor values may require adjustment for circuits with fixed voltage supplies. The maximum variance is 0.4V difference between the lowest (MV8102 at 1.7V) and highest (MV3750 at 2.2V) forward voltage specifications.

Q: Are all substitutes RoHS compliant?

A: MV8141 and OVLLR8C7 carry RoHS3 compliance certification. MV8102 and MV3750 do not list RoHS status in provided specifications. 5RD is RoHS3 compliant. Verify RoHS requirements for your application before component selection.

Q: Which substitute has the longest available product lifecycle?

A: MV8141 (Fairchild Semiconductor) and OVLLR8C7 (TT Electronics/Optek Technology) both carry active product status, indicating continued manufacturer support. Obsolete parts (5SURC, MV8102, MV3750) should not be selected for new designs requiring long-term availability.

Q: What is the mechanical compatibility with PCB layouts?

A: All substitutes use T-1 3/4 5mm through-hole packages with radial lead configurations, maintaining standard PCB footprint compatibility. Height variations exist: 5SURC and 5RD at 8.50mm, MV8102 and MV3750 near 8.9mm, and OVLLR8C7 at 6.80mm. Verify mechanical clearance in applications with height constraints.
