H101CRD LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The H101CRD is an active production LED circuit board indicator manufactured by Bivar Inc. This component is a single red diffused LED with a 3mm T-1 through-hole right-angle configuration, designed for PCB mounting applications requiring visual status indication. The part operates at 2.1V with a peak wavelength of 700nm and delivers 2mcd brightness output. Finding equivalent substitute parts becomes necessary when managing inventory across multiple suppliers, accommodating design revisions, or addressing component availability constraints while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H101CRD are identified based on strict alignment with the following critical parameters: color (red), configuration (single), lens style (round with domed top), mounting type (through hole, right angle), and compliance certifications (ROHS3). The substitute parts listed maintain these core functional and mechanical characteristics while operating within acceptable electrical parameter ranges for LED circuit board indicator applications.

The two identified substitutes are:

5502408F (Dialight): Maintains red color, single configuration, diffused round domed lens, and through-hole right-angle mounting. Operates at higher voltage (6.3V) and current (20mA) with larger 5mm T-1 3/4 lens size and increased brightness (6.3mcd).

5510407F (Dialight): Maintains red color, single configuration, diffused tinted round domed lens, and through-hole right-angle mounting. Operates at comparable voltage (2V) and lower current (10mA) with matching 3mm T-1 lens size and higher brightness (10mcd).

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, confirming suitability for standard PCB assembly and storage conditions without special handling requirements.

5510407F Selection: This substitute is the closest functional equivalent to the H101CRD. Both parts share identical lens size (3mm T-1), mounting configuration (through hole, right angle), and comparable voltage ratings (2V vs. 2.1V). The 5510407F provides higher brightness output (10mcd vs. 2mcd) while maintaining the same mechanical footprint. This part is appropriate for direct substitution in applications where increased luminous intensity is acceptable or beneficial.

5502408F Selection: This substitute differs significantly in physical dimensions (5mm T-1 3/4 vs. 3mm T-1) and electrical requirements (6.3V, 20mA vs. 2.1V). The larger lens size and higher voltage rating require PCB layout modifications and circuit redesign. This part is suitable only when design constraints permit larger component footprints and higher operating voltages.

Frequently Asked Questions (FAQ)

Q: Can 5510407F directly replace H101CRD without PCB modifications?

A: Yes. Both parts use identical 3mm T-1 lens size and through-hole right-angle mounting. Voltage ratings are comparable (2V vs. 2.1V). No PCB layout changes are required. Circuit current-limiting resistor values may require adjustment due to brightness difference (10mcd vs. 2mcd).

Q: What are the mechanical compatibility constraints for 5502408F substitution?

A: The 5502408F uses a larger 5mm T-1 3/4 lens compared to the 3mm T-1 of the H101CRD. PCB hole spacing and component clearances must accommodate the larger diameter. Through-hole mounting remains compatible, but physical board layout modifications are necessary.

Q: How do wavelength differences affect visual appearance?

A: The H101CRD operates at 700nm (deep red), while both Dialight substitutes operate at 650nm (standard red). The 700nm wavelength produces a deeper red appearance. The 650nm wavelength appears as a brighter, more standard red. Color perception differences are visible under identical lighting conditions.

Q: Are all three parts suitable for high-temperature applications?

A: Temperature operating ranges are not provided in the available parameters. Thermal performance specifications must be obtained from manufacturer datasheets before selecting parts for temperature-critical applications.

Q: What packaging differences exist between these parts?

A: H101CRD is supplied in Tray packaging. Both Dialight substitutes (5502408F and 5510407F) are supplied in Bulk packaging. Packaging format affects inventory management, handling procedures, and component counting during assembly operations.

Q: Can brightness differences between parts affect circuit design?

A: Yes. The H101CRD delivers 2mcd, while 5510407F delivers 10mcd and 5502408F delivers 6.3mcd. Higher brightness requires lower current-limiting resistor values to maintain equivalent visual intensity. Circuit redesign is necessary to prevent over-driving the substitute parts and ensure consistent brightness across production units.
