Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OVLEW3CB6 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: White
• Lens Transparency: Clear
• Mounting Type: Through Hole
• Package / Case: Radial
• Lens Style: Round with Domed Top
• Current - Test: 20mA
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf): 2.8V to 3.4V range acceptable
• Millicandela Rating: 2100mcd minimum
• Viewing Angle: 15° to 50° range acceptable
• Lens Size: 5mm form factor (5.00mm Dia or T-1 3/4 equivalent)
• Height (Max): 8.65mm to 13.00mm range acceptable

All substitute parts listed maintain white color, clear lens transparency, through-hole radial mounting, and domed-top lens style. Variations in forward voltage, brightness, and viewing angle fall within acceptable operational ranges for LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status, providing long-term component availability compared to the obsolete OVLEW3CB6. Selection should be based on the following criteria:

For Direct Voltage and Brightness Match: LTW-2R3D7 operates at the same 3.4V forward voltage as the original part with comparable 4200mcd brightness. This part maintains the closest electrical characteristics and is ROHS3 compliant with active product status.

For Exact Viewing Angle Match (30°): 334-15/T1C3-7TVA provides identical 30° viewing angle with 3.2V forward voltage and higher 10700mcd brightness. This part is suitable for applications where viewing angle specification is critical.

For Maximum Brightness with Narrow Viewing Angle: LTW-2S3D8 delivers the highest brightness at 23000mcd with 2.8V forward voltage and 15° narrow viewing angle. This part is appropriate for applications requiring high luminous intensity with directional output.

For Warm White Color Option: 334-15/X1C2-1UWA provides warm white color variant at 3.2V with 13500mcd brightness and 20° viewing angle. This part is ROHS3 compliant and suitable for applications requiring warm white indication.

For Broader Viewing Angle: 334-15/F1C5-1RTA offers the widest 50° viewing angle with 3.2V forward voltage and 6750mcd brightness, suitable for applications requiring wide-angle visibility.

All substitute parts maintain through-hole radial mounting, clear lens transparency, round domed-top lens style, and MSL 1 moisture sensitivity rating. Forward voltage variations (2.8V to 3.4V) are within acceptable operating ranges for standard LED indication circuits.

Frequently Asked Questions (FAQ)

Q: Can OVLEW3CB6 be directly replaced with any of these substitute parts?

A: Yes, all listed parts are electrically and mechanically compatible substitutes. They maintain identical mounting type (through-hole radial), lens style (round domed-top), color (white), and lens transparency (clear). Forward voltage ranges from 2.8V to 3.4V, which is acceptable for standard LED indication applications. Verify your circuit design accommodates the forward voltage and brightness variations of your selected substitute.

Q: What is the difference between 5.00mm Dia and T-1 3/4 lens sizes?

A: Both designations refer to 5mm form factor LEDs. T-1 3/4 is an alternative industry designation for the same physical size. Parts with either designation are mechanically compatible in standard 5mm LED mounting positions.

Q: Which substitute part has the closest electrical match to OVLEW3CB6?

A: LTW-2R3D7 matches the original 3.4V forward voltage and provides comparable 4200mcd brightness. This part maintains the same electrical operating point as the obsolete OVLEW3CB6.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant, ensuring compliance with current environmental and regulatory standards. The original OVLEW3CB6 RoHS status was not specified.

Q: How do brightness ratings affect circuit design?

A: Brightness (mcd rating) is determined by the LED's luminous intensity at the specified test current (20mA for all parts listed). Higher mcd ratings produce brighter indication at the same current. Circuit design remains unchanged; brightness differences are inherent to the LED component and do not require circuit modifications.

Q: What viewing angle should I select?

A: Viewing angle determines the cone of light distribution. Narrow angles (15°-20°) provide directional indication, while wider angles (40°-50°) provide visibility across a broader range. Select based on your application's visibility requirements and mounting position.

Q: Can I use LTW-2S3D8 with lower forward voltage (2.8V) in existing circuits?

A: LTW-2S3D8 operates at 2.8V compared to OVLEW3CB6's 3.4V. This 0.6V difference reduces voltage drop across the LED, increasing voltage across the current-limiting resistor. Verify your circuit's resistor value accommodates this change to maintain proper 20mA test current operation.

Q: Is warm white color (334-15/X1C2-1UWA) compatible with white color applications?

A: Warm white is a color variant of white and is mechanically and electrically compatible. Use only if your application accepts warm white color appearance. For strict white color matching, select parts designated as white only.
