Key Parameters

Substitute Part Grouping Explanation

Substitution for the OVLEW5CB6 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color: White
• Lens Color: Colorless
• Lens Transparency: Clear
• Lens Style: Round with Domed Top
• Lens Size: 5mm or T-1 3/4 (equivalent form factor)
• Mounting Type: Through Hole
• Package / Case: Radial
• Current - Test: 20mA
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8541.41.0000

Secondary Compatibility Parameters (allowable variance):

• Voltage - Forward (Vf): 2.8V to 3.6V range
• Millicandela Rating: 740mcd to 23000mcd range
• Viewing Angle: 15° to 50° range
• Height (Max): 8.60mm to 12.10mm range

All substitute parts listed below meet the primary criteria and fall within the secondary parameter ranges, ensuring functional compatibility with the original OVLEW5CB6 design specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status, providing supply continuity for the obsolete OVLEW5CB6. Selection among substitutes depends on specific application requirements within the allowable parameter ranges.

Lite-On LTW-2 Series (LTW-2L3DV5S, LTW-2R3D7, LTW-2S3D7, LTW-2S3D8): All variants are ROHS3 compliant and maintain REACH Unaffected status. These parts offer the broadest range of brightness options (4200mcd to 23000mcd) and forward voltage options (2.8V to 3.4V), accommodating diverse circuit designs. The LTW-2 base product number indicates a common platform with established supply chain availability.

Lumex SLX-LX5093UWC/C: Provides 3500mcd brightness at 3.4V forward voltage with 40° viewing angle, offering a mid-range brightness option with ROHS3 compliance and REACH Unaffected status.

Lumex SSL-LX5093UWC/A: Delivers the lowest brightness option at 740mcd with 3.6V forward voltage and 45° viewing angle. This part is suitable for applications requiring reduced light intensity while maintaining ROHS3 compliance and REACH Unaffected status.

All substitute parts maintain identical mounting type (through hole), package configuration (radial), lens characteristics (5mm clear domed), and test current (20mA) as the original OVLEW5CB6.

Frequently Asked Questions (FAQ)

Q: Can LTW-2S3D8 replace OVLEW5CB6 in all applications?

A: LTW-2S3D8 is electrically compatible as a substitute. It operates at 2.8V forward voltage (0.6V lower than OVLEW5CB6), provides significantly higher brightness (23000mcd vs. 1600mcd), and features a narrower viewing angle (15° vs. 50°). Circuit designs must accommodate the lower forward voltage. Applications requiring the original 50° viewing angle should consider LTW-2L3DV5S or SLX-LX5093UWC/C instead.

Q: What is the difference between T-1 3/4 and 5mm lens size designations?

A: T-1 3/4 and 5mm refer to the same physical form factor for through-hole LEDs. Both designations describe a 5mm diameter lens. The substitute parts use T-1 3/4 nomenclature while the original OVLEW5CB6 specifies 5.00mm Dia. These are mechanically equivalent for PCB mounting and hole spacing.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are ROHS3 compliant. The original OVLEW5CB6 does not specify RoHS status in the provided data. All substitutes meet current environmental compliance requirements.

Q: How do brightness differences affect circuit design?

A: Brightness (millicandela rating) is determined by the LED's internal efficiency and does not affect electrical circuit compatibility. Forward voltage (Vf) and test current (20mA) remain constant across all substitutes. Circuit designs based on the original OVLEW5CB6 specifications will function with any substitute part without modification, though perceived brightness will vary according to the millicandela rating of the selected substitute.

Q: Which substitute offers the closest match to OVLEW5CB6 specifications?

A: LTW-2R3D7 provides the closest electrical match with identical 3.4V forward voltage and 20mA test current. It offers 4200mcd brightness (2.6x the original) with a narrower 35° viewing angle compared to the original 50°. For applications requiring the original 50° viewing angle, LTW-2L3DV5S matches this specification exactly while operating at 3.3V forward voltage.

Q: What is the inventory status of substitute parts?

A: LTW-2S3D8 has the highest inventory availability at 40,200 pieces. LTW-2R3D7 has 23,179 pieces. LTW-2S3D7 has 16,640 pieces. SLX-LX5093UWC/C has 12,582 pieces. LTW-2L3DV5S has 922 pieces. SSL-LX5093UWC/A has the lowest availability at 1,033 pieces. All parts are listed as new original stock.
