H101CRDL LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The H101CRDL is an LED Circuit Board Indicator manufactured by Bivar Inc., classified as a single red diffused light-emitting diode in a 3mm T-1 form factor with right-angle through-hole mounting. This component is in active product status and is ROHS3 compliant. Finding alternative models becomes necessary when the specific packaging format (tray), optical characteristics (2.1V forward voltage, 1mcd brightness), or mechanical configuration (3mm lens, domed top) must be adapted to match alternative sourcing, board space constraints, or supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

The part 5502408F from Dialight is listed as a substitute based on the following alignment criteria:

Common Parameters:

• Color: Red
• Configuration: Single
• Lens Type: Diffused
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole, Right Angle
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

Varying Parameters Affecting Substitution:

• Lens Size: 5mm T-1 3/4 (larger than 3mm T-1)
• Voltage Rating: 6.3V (higher than 2.1V)
• Current: 20mA (specified, whereas H101CRDL current is not specified)
• Millicandela Rating: 6.3mcd (higher than 1mcd)
• Viewing Angle: 50° (wider than 40°)
• Wavelength - Peak: 650nm (different from 700nm)
• Packaging: Bulk (different from Tray)

Substitution of 5502408F for H101CRDL is applicable only when the application permits the larger mechanical envelope (5mm vs. 3mm), higher voltage operation (6.3V vs. 2.1V), increased brightness (6.3mcd vs. 1mcd), and different spectral output (650nm vs. 700nm).

Parameter Comparison

Engineering Selection Recommendations

Both H101CRDL and 5502408F are active products with ROHS3 compliance and MSL 1 ratings, indicating continuous availability and environmental compliance with current regulations. The H101CRDL is suitable for low-voltage, low-brightness indicator applications, whereas 5502408F is designed for higher-voltage systems requiring greater optical output. Selection between these parts depends on the electrical operating parameters (2.1V vs. 6.3V), physical space allocation (3mm vs. 5mm lens diameter), and brightness requirements (1mcd vs. 6.3mcd) specified in the target application.

Frequently Asked Questions (FAQ)

Q: Can 5502408F be used directly as a replacement for H101CRDL?

A: Direct substitution is not recommended without circuit design review. The 5502408F requires 6.3V operation compared to H101CRDL's 2.1V rating, and the larger 5mm lens may not fit in designs intended for 3mm T-1 components. Board layout and electrical schematic modifications may be necessary.

Q: What are the primary differences in optical performance?

A: The H101CRDL produces 1mcd at a peak wavelength of 700nm with a 40° viewing angle, while 5502408F produces 6.3mcd at 650nm with a 50° viewing angle. These differences affect visibility distance, spectral color perception, and angular light distribution in the application circuit.

Q: Are both parts suitable for high-reliability applications?

A: Both H101CRDL and 5502408F are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), making them suitable for standard commercial and industrial environments. Both are in active product status with current manufacturing support.

Q: Why is packaging listed differently for these parts?

A: H101CRDL is supplied in tray packaging, while 5502408F is supplied in bulk packaging. Packaging format does not affect electrical or optical performance but may impact procurement quantities, cost per unit, and handling procedures in manufacturing environments.

Q: What mounting compatibility considerations apply?

A: Both parts feature through-hole, right-angle mounting, ensuring mechanical compatibility with standard PCB footprints for right-angle LED configurations. The mechanical fit depends on lens diameter (3mm vs. 5mm) and lead spacing, which must be verified against the target PCB design.
