H101CHDL

Part Overview

The H101CHDL is a Circuit Board Indicator LED manufactured by Bivar Inc., featuring a single red diffused 3mm T-1 through-hole configuration with right-angle mounting. This component is currently in active production status with 620 pieces in stock. Identification of equivalent substitute components is necessary to ensure design flexibility, manage supply chain continuity, and provide alternative sourcing options when the primary component becomes unavailable or when design specifications allow for functionally compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the H101CHDL is based on the following allowed electrical and mechanical parameters:

• Color: Red
• Configuration: Single LED
• Lens Type: Diffused
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole, Right Angle
• RoHS Compliance: ROHS3 Compliant

The substitute part 5502408F is classified as a functionally compatible alternative based on these parameters. Variances in lens size (5mm vs. 3mm), voltage rating (6.3V vs. 2V), current specification (20mA vs. unspecified), millicandela rating (6.3mcd vs. 3mcd), viewing angle (50° vs. 40°), and wavelength (650nm vs. 625nm) represent allowable deviations within the component category. These variations permit substitution in applications where the design electrical specifications accommodate the higher voltage and current requirements, and where the increased brightness and viewing angle do not create design conflicts.

Parameter Comparison

Engineering Selection Recommendations

Both the H101CHDL and 5502408F meet ROHS3 compliance and carry unlimited MSL ratings, ensuring regulatory and environmental storage compatibility. The primary selection criterion depends on circuit voltage and current availability. The H101CHDL operates at 2V with unspecified current, while the 5502408F requires 6.3V at 20mA. Selection of the 5502408F as a substitute is valid only when the circuit design provides 6.3V supply voltage and can deliver 20mA without exceeding current budget constraints. The 5mm lens size of the 5502408F versus the 3mm lens of the H101CHDL introduces a mechanical design consideration requiring verification of mounting hole spacing and clearance within the target application.

Frequently Asked Questions (FAQ)

Can I substitute the 5502408F for the H101CHDL in any circuit?

Substitution is valid only when the circuit provides 6.3V operating voltage and 20mA current capacity. The H101CHDL is rated at 2V, making direct substitution invalid in circuits designed for 2V operation without additional voltage regulation or current-limiting modifications.

What are the mechanical compatibility considerations?

The 5502408F has a 5mm lens diameter (T-1 3/4) compared to the H101CHDL's 3mm lens diameter (T-1). Both use right-angle through-hole mounting. Physical clearance and mounting hole alignment must be verified before substitution to ensure the larger lens does not interfere with adjacent components or circuit board layout.

Are both parts compliant with the same regulatory standards?

Both the H101CHDL and 5502408F are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent regulatory and environmental compliance. The H101CHDL carries ECCN EAR99 classification, and the 5502408F carries REACH Unaffected status in addition to ECCN EAR99.

What is the brightness difference between these two LEDs?

The 5502408F produces 6.3mcd at its rated 20mA current, while the H101CHDL produces 3mcd. This represents a 2.1× increase in brightness. Designs sensitive to illumination intensity must account for this brightness variance, as the substitute part may exceed visual output requirements.

How do the wavelengths differ?

The H101CHDL has a peak wavelength of 625nm (standard red), while the 5502408F is 650nm (deep red). This 25nm difference may produce perceptibly different color appearance under identical lighting conditions, which is relevant in applications where specific color matching is required.
