H101CHC

Part Overview

The H101CHC is a Circuit Board Indicator LED manufactured by Bivar Inc., featuring a single red clear lens in a 3mm T-1 package format. This part is rated at 2V and 20mA with a peak wavelength of 625nm and 50mcd brightness rating. The product status is Obsolete, necessitating identification of active substitute components for continued design compatibility and procurement availability.

Key Parameters

Substitute Part Grouping Explanation

The H101CHD is established as a substitute for the H101CHC based on shared core electrical and mechanical parameters within the H101C series. Both components maintain identical voltage rating (2V), lens size (3mm T-1), and round domed top lens style. Both are red LEDs with 625nm peak wavelength and share the same series designation, confirming manufacturing compatibility.

Substitution is appropriate where the following parameter variations are acceptable:

• Lens Type: Clear (H101CHC) to Diffused (H101CHD)
• Current Rating: 20mA (H101CHC) to unspecified (H101CHD)
• Millicandela Rating: 50mcd (H101CHC) to 30mcd (H101CHD)
• Viewing Angle: 30° (H101CHC) to 40° (H101CHD)
• Mounting Configuration: Unspecified for H101CHC versus Through Hole, Right Angle for H101CHD
• Product Status: Obsolete (H101CHC) to Active (H101CHD)

Parameter Comparison

Engineering Selection Recommendations

The H101CHD is currently available as an active product within the H101C series and is certified ROHS3 compliant. The H101CHC is obsolete, making the H101CHD the appropriate selection for new procurement and design implementation. Both components share identical voltage, lens size, and series designation.

Selection between these components requires consideration of application-specific performance requirements regarding brightness output (50mcd versus 30mcd), viewing angle characteristics (30° versus 40°), and lens optical properties (clear versus diffused). The H101CHD offers wider viewing angle and is specified for right-angle through-hole mounting, while the H101CHC clear lens provides higher brightness at a narrower viewing angle.

Frequently Asked Questions (FAQ)

Q: Can H101CHD directly replace H101CHC in existing designs? A: H101CHD shares the same voltage rating (2V), wavelength (625nm), lens size (3mm T-1), and series designation with H101CHC. Direct substitution is mechanically and electrically feasible where application requirements permit tolerance of reduced brightness (30mcd vs. 50mcd), wider viewing angle (40° vs. 30°), and diffused lens characteristics instead of clear lens performance.

Q: What are the primary differences between H101CHC and H101CHD? A: The main differences are lens type (clear versus diffused), brightness output (50mcd versus 30mcd), viewing angle (30° versus 40°), and product status (obsolete versus active). The H101CHD is specified with right-angle through-hole mounting configuration.

Q: Why is H101CHC listed as obsolete? A: Product obsolescence is determined by manufacturer discontinuation. The active substitute H101CHD within the same H101C series provides continuity for applications requiring red indicator LEDs in 3mm T-1 packages.

Q: Are there packaging considerations when switching from H101CHC to H101CHD? A: H101CHD is packaged in trays with specified through-hole, right-angle mounting. Verify that PCB layout and assembly processes accommodate right-angle lead configuration if transitioning from the original H101CHC design.

Q: Does MSL rating affect substitution decisions? A: Both H101CHC and H101CHD share identical MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage, handling, or shipping.
