5BWC12V LED Blue Clear T-1 3/4 Through Hole

Part Overview

The 5BWC12V is a blue LED indication component manufactured by Bivar Inc., rated for 12V operation with a 5mm T-1 3/4 form factor. This product is classified as obsolete, necessitating evaluation of active substitute components to maintain system design continuity. The 5BWC12V features a clear, domed lens design with 30mcd brightness rating and is designed for through-hole mounting applications requiring discrete 12V LED indication.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 5BWC12V are classified based on electrical and mechanical compatibility parameters. The primary substitution criteria are: forward voltage rating (12V operation), lens form factor (5mm T-1 3/4 through-hole radial configuration), color specification (blue), lens transparency (clear), viewing angle (20°), and mounting methodology (through-hole radial).

Two substitute components meet these parameters:

1. 5BWC (Parametric Equivalent) - Bivar Inc. active component with identical form factor, lens specifications, and viewing angle, differing in forward voltage (4V) and test current (20mA)

2. LTH5MM12VFR4600 (Similar Equivalent) - Visual Communications Company (VCC) active component maintaining 12V forward voltage operation with identical form factor, lens design, and viewing angle specifications

Parameter Comparison

Engineering Selection Recommendations

5BWC (Bivar Inc.): This component maintains active product status and ROHS3 compliance. It retains identical mechanical and optical specifications to the 5BWC12V, including form factor, lens design, and viewing angle. The forward voltage difference (4V versus 12V) requires circuit redesign considerations and is applicable only in designs tolerating voltage variation. Current draw increases to 20mA at test conditions.

LTH5MM12VFR4600 (VCC): This component maintains 12V forward voltage compatibility with the original 5BWC12V, eliminating voltage-related circuit modifications. It preserves identical mechanical specifications and viewing angle. ROHS3 compliance and active product status support long-term supply continuity. Notable differences include significantly increased brightness (2000mcd versus 30mcd), wavelength shift (470nm peak versus 430nm), and increased mechanical height (9.95mm versus 8.50mm). The elevated brightness may require optical design or electrical network adjustments in layouts sensitive to light intensity.

Frequently Asked Questions (FAQ)

Q: Can the 5BWC12V be directly replaced by the 5BWC without circuit modification? A: No. The 5BWC operates at 4V forward voltage compared to the 5BWC12V at 12V. Direct substitution requires series resistor recalculation and verification of circuit voltage supply compatibility.

Q: Is the LTH5MM12VFR4600 a direct mechanical and electrical substitute? A: The LTH5MM12VFR4600 maintains 12V forward voltage and identical form factor (5mm T-1 3/4 through-hole radial). The maximum height difference (9.95mm versus 8.50mm) requires PCB layout clearance verification. The 2000mcd brightness is significantly higher than the original 30mcd rating and may necessitate optical or electrical network adjustments depending on design requirements.

Q: Why is the 5BWC12V classified as obsolete? A: Obsolescence indicates the manufacturer has discontinued production. Active substitute options are available from Bivar Inc. (5BWC) and VCC (LTH5MM12VFR4600) to support ongoing design requirements.

Q: What is the significance of the wavelength peak difference (430nm versus 470nm)? A: The 5BWC12V and 5BWC operate at 430nm peak wavelength, while the LTH5MM12VFR4600 operates at 470nm. This shift represents a change in the blue spectrum perception and may impact color matching in multi-color indicator applications.

Q: Are both substitute components RoHS compliant? A: Yes. Both the 5BWC and LTH5MM12VFR4600 carry ROHS3 compliance certification, meeting environmental and material restriction requirements for electronic component applications.

Q: What is the moisture sensitivity level difference between substitutes? A: The 5BWC carries MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The LTH5MM12VFR4600 carries MSL 2 (1 Year), requiring protective storage and handling protocols to maintain component reliability.
