LTL42CB6N Equivalent & Substitute Parts

Part Overview

The LTL42CB6N is a blue 470nm LED indication component manufactured by Lite-On Inc., configured as a 3mm T-1 through-hole radial device. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The component operates at a forward voltage of 3.5V with a test current of 20mA and delivers 1900mcd luminous intensity with a 50° viewing angle.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTL42CB6N is determined by the following parameters:

• Color: Blue
• Wavelength - Dominant: 470nm
• Lens Size: 3mm or 3.00mm Dia
• Mounting Type: Through Hole
• Package / Case: Radial
• Current - Test: 20mA

The substitute parts listed maintain these core parameters while allowing variation in forward voltage (Vf), millicandela rating, and viewing angle within acceptable operational ranges for LED indication applications. All substitutes are active products with current manufacturing status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status and meet the core functional requirements of the obsolete LTL42CB6N. Selection among substitutes should be based on specific application requirements:

151033BS03000 (Würth Elektronik) offers the highest luminous intensity at 3800mcd with the lowest forward voltage at 2.8V, suitable for applications requiring maximum brightness efficiency. This part carries ROHS3 compliance and unlimited moisture sensitivity rating.

204-10SUBC/S400-A4 (Everlight Electronics Co Ltd) provides the narrowest viewing angle at 20° with moderate luminous intensity at 800mcd, appropriate for directional indication applications. Forward voltage is 3.4V, closely matching the original specification.

3294-15SUBC/S400-A6 (Everlight Electronics Co Ltd) delivers the widest viewing angle at 90° with the lowest luminous intensity at 320mcd, suitable for wide-angle indication requirements. This part has the lowest maximum height at 4.45mm and carries ROHS3 compliance.

OVLBB4C7 (TT Electronics / Optek Technology) provides luminous intensity of 1800mcd with a 45° viewing angle and 3.2V forward voltage, offering the closest performance match to the original LTL42CB6N. This part maintains T-1 package designation and carries ROHS3 compliance with unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitutes directly in place of the LTL42CB6N?

A: All four substitutes share the same core parameters: blue color, 470nm dominant wavelength, 3mm lens size, through-hole mounting, radial package, and 20mA test current. Direct substitution is mechanically and electrically feasible. However, forward voltage variations (2.8V to 3.4V) and luminous intensity differences (320mcd to 3800mcd) may affect circuit performance and require verification in your specific application.

Q: What is the primary difference between these substitutes?

A: The substitutes vary primarily in forward voltage, luminous intensity, and viewing angle. The 151033BS03000 offers highest brightness, the 3294-15SUBC/S400-A6 provides the widest viewing angle, and the OVLBB4C7 most closely matches the original electrical characteristics.

Q: Are all substitutes RoHS3 compliant?

A: Three of the four substitutes carry explicit ROHS3 compliance: 151033BS03000, 3294-15SUBC/S400-A6, and OVLBB4C7. The 204-10SUBC/S400-A4 does not specify RoHS status in the provided data.

Q: How do viewing angle differences affect application suitability?

A: Viewing angle determines the cone of light distribution. The 204-10SUBC/S400-A4 at 20° provides narrow directional indication, while the 3294-15SUBC/S400-A6 at 90° provides wide-angle visibility. The original LTL42CB6N at 50° and OVLBB4C7 at 45° offer intermediate coverage.

Q: What packaging options are available?

A: The 151033BS03000 and 3294-15SUBC/S400-A6 are supplied in Bulk packaging. The 204-10SUBC/S400-A4 is supplied in Tape & Reel format. The OVLBB4C7 is supplied in Bulk packaging.
