H101CSRD LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The H101CSRD is a 3mm red LED circuit board indicator manufactured by Bivar Inc., designed for through-hole, right-angle mounting applications. This component features a diffused lens with domed top, operating at 1.7V with a peak wavelength of 645nm and 40mcd brightness rating. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical performance parameters are required due to inventory constraints, design flexibility, or application-specific mounting requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the H101CSRD is based on the following allowed electrical and mechanical parameters:

Primary Compatibility Criteria:

• Color: Red (wavelength range 645nm–650nm acceptable)
• Configuration: Single LED
• Lens Type: Diffused
• Mounting Type: Through Hole, Right Angle
• RoHS Compliance: ROHS3 Compliant

Secondary Consideration Parameters:

• Lens Size: 3mm or 5mm (both T-1 series form factors)
• Voltage Rating: Operating voltage within circuit design tolerance
• Millicandela Rating: Brightness level suitable for indicator function

The substitute part 5502408F (Dialight 550 series) shares the core functional characteristics of red diffused LED with right-angle through-hole mounting and ROHS3 compliance. Physical differences in lens size (5mm vs. 3mm) and electrical parameters (voltage and current ratings) represent design trade-offs that may be accommodated depending on application requirements and PCB layout constraints.

Engineering Selection Recommendations

H101CSRD Selection Criteria:

• Applications requiring 3mm form factor with standard T-1 through-hole footprint
• Circuits designed for low-voltage operation (1.7V forward voltage)
• Designs requiring 40mcd brightness level with 40° viewing angle
• Bivar Inc. supply chain preference or existing qualification

5502408F Selection Criteria:

• Applications accommodating 5mm lens size (T-1 3/4 form factor)
• Circuits with higher voltage supply (6.3V operation)
• Designs benefiting from wider 50° viewing angle
• Dialight supply chain preference or existing qualification
• Applications where lower brightness (6.3mcd) is acceptable

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), meeting equivalent environmental and regulatory requirements. Selection between these parts depends on PCB layout constraints, circuit voltage design, and brightness requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can 5502408F directly replace H101CSRD in existing PCB designs?

A: Direct replacement requires verification of three factors: (1) PCB footprint accommodation for 5mm lens size versus 3mm, (2) circuit voltage compatibility with 6.3V forward voltage versus 1.7V, and (3) brightness level acceptance of 6.3mcd versus 40mcd. Physical and electrical modifications may be necessary.

Q: What is the primary difference between these two parts?

A: The H101CSRD is a compact 3mm indicator designed for low-voltage circuits (1.7V), while the 5502408F is a larger 5mm indicator for higher-voltage applications (6.3V). The H101CSRD provides higher brightness (40mcd), while the 5502408F offers a wider viewing angle (50° versus 40°).

Q: Are both parts RoHS compliant?

A: Yes, both H101CSRD and 5502408F are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity), meeting equivalent environmental standards.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements: choose H101CSRD for compact 3mm form factor with low-voltage operation, or 5502408F for larger 5mm form factor with higher-voltage circuits and wider viewing angle requirements.

Q: Do these parts have different packaging formats?

A: Yes, H101CSRD is supplied in Tray packaging, while 5502408F is supplied in Bulk packaging. Packaging format may affect inventory management and handling procedures.
