H101CHD Equivalent & Substitute Parts

Part Overview

The H101CHD is an active LED circuit board indicator manufactured by Bivar Inc. This component is a single red diffused LED in a 3mm T-1 through-hole right-angle configuration, designed for applications requiring low-voltage indicator lighting. The H101CHD operates at 2V with a peak wavelength of 625nm and delivers 30 millicandela output with a 40° viewing angle.

Substitute parts are identified when equivalent functional performance can be achieved through alternative manufacturers while maintaining compatibility with the intended application's electrical and mechanical constraints. The H101CHD has one identified substitute part within the Dialight 550 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H101CHD is determined by the following critical parameters:

Functional Compatibility Criteria:

• Color: Red
• Configuration: Single
• Lens Type: Diffused
• Mounting Type: Through Hole, Right Angle
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Application-Dependent Criteria:

• Voltage Rating
• Current Rating
• Millicandela Output
• Viewing Angle
• Lens Size
• Wavelength - Peak

The substitute part 5502408F from Dialight shares the same functional classification (red diffused single LED with through-hole right-angle mounting) and compliance certifications. However, this substitute operates at different electrical parameters (6.3V versus 2V) and physical dimensions (5mm T-1 3/4 versus 3mm T-1), requiring circuit design verification for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

H101CHD (Bivar Inc.) is the primary component for applications requiring a 2V red LED indicator with 3mm form factor and 30mcd output intensity. This part maintains active product status and full ROHS3 compliance with unlimited moisture sensitivity rating.

5502408F (Dialight) serves as a substitute only in applications where the following conditions are met:

1. Circuit design accommodates 6.3V operating voltage instead of 2V
2. Physical board layout permits 5mm T-1 3/4 lens size instead of 3mm T-1
3. Application tolerates reduced millicandela output (6.3mcd versus 30mcd)
4. Increased viewing angle (50° versus 40°) is acceptable or beneficial

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and regulatory compliance. The substitute part is available in bulk packaging with higher inventory levels (2721 pieces) compared to the primary part (930 pieces in tray packaging).

Frequently Asked Questions (FAQ)

Q: Can the 5502408F directly replace the H101CHD in existing designs?

A: Direct replacement is not possible without circuit modification. The 5502408F requires 6.3V operation versus the H101CHD's 2V rating. Additionally, the 5mm lens size differs from the 3mm form factor, requiring PCB layout changes. The substitute part delivers significantly lower brightness (6.3mcd versus 30mcd).

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (2V versus 6.3V), lens size (3mm versus 5mm), millicandela output (30mcd versus 6.3mcd), and wavelength peak (625nm versus 650nm). Both share identical mounting type (through-hole right angle), lens style (diffused round with domed top), and compliance certifications.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the H101CHD and 5502408F are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), ensuring equivalent environmental compliance for regulated applications.

Q: What is the viewing angle difference between these parts?

A: The H101CHD provides a 40° viewing angle, while the 5502408F offers a 50° viewing angle. The wider viewing angle of the substitute may be advantageous in applications requiring broader light distribution.

Q: How do the packaging options differ?

A: The H101CHD is supplied in tray packaging with 930 pieces in stock. The 5502408F is supplied in bulk packaging with 2721 pieces available, offering higher volume availability for the substitute part.

Q: Can I use the 5502408F in a 2V circuit?

A: No. The 5502408F is rated for 6.3V operation. Using it in a 2V circuit will result in insufficient current and non-functional operation. Circuit redesign is required to accommodate the substitute part's voltage requirements.
