PCH125-BR LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The PCH125-BR is a 3mm red LED circuit board indicator manufactured by Visual Communications Company (VCC). This component is a single red diffused LED with a round domed top, designed for through-hole right-angle mounting applications. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support, maintenance, and production continuity.

The PCH125-BR operates at 20mA with a peak wavelength of 635nm and delivers 14mcd brightness. Its 60° viewing angle and diffused lens provide wide-angle illumination suitable for status indication applications on circuit boards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCH125-BR is based on the following critical parameters that must align across equivalent parts:

Mandatory Matching Parameters:

• Color: Red (635nm peak wavelength)
• Lens Size: 3mm, T-1 form factor
• Lens Style: Round with Domed Top
• Lens Type: Diffused
• Mounting Type: Through Hole, Right Angle
• Configuration: Single LED
• RoHS Compliance: ROHS3 Compliant

Allowable Parameter Variations: Substitute parts may differ in current rating, millicandela output, and viewing angle within the constraints of the same physical package and optical characteristics. These variations are acceptable when the substitute part can be integrated into the same circuit board layout and mounting footprint.

The H100CHDL from Bivar Inc. meets all mandatory matching parameters and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The H100CHDL from Bivar Inc. is a suitable substitute for the obsolete PCH125-BR based on the following engineering criteria:

Physical Compatibility: Both parts share identical lens size (3mm, T-1), lens style (round with domed top), and mounting configuration (through-hole, right-angle). Circuit board layouts and mechanical mounting fixtures designed for the PCH125-BR will accommodate the H100CHDL without modification.

Optical Compatibility: Both parts emit red light at 635nm peak wavelength with diffused lens characteristics. The H100CHDL produces 6mcd compared to the PCH125-BR's 14mcd, representing a reduction in brightness output. The H100CHDL has a 45° viewing angle versus the PCH125-BR's 60° viewing angle, resulting in a narrower illumination cone.

Regulatory Compliance: Both parts meet ROHS3 compliance requirements, ensuring compatibility with current environmental and regulatory standards for electronic component manufacturing and assembly.

Product Status: The H100CHDL is classified as an active product with current manufacturing support from Bivar Inc., providing long-term availability and supply chain stability compared to the obsolete PCH125-BR.

Electrical Considerations: The H100CHDL operates at 1.8V with unspecified current rating. Circuit designs must be evaluated to confirm that the lower brightness output (6mcd versus 14mcd) and narrower viewing angle (45° versus 60°) are acceptable for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the H100CHDL be used as a direct replacement for the PCH125-BR without circuit modification?

A: The H100CHDL is mechanically and optically compatible with the PCH125-BR due to matching lens size, style, and mounting type. However, electrical circuit evaluation is required. The H100CHDL operates at 1.8V with unspecified current rating, while the PCH125-BR operates at 20mA. Circuit designs must be verified to confirm compatibility with the H100CHDL's electrical specifications.

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

A: The primary differences are brightness output (H100CHDL: 6mcd versus PCH125-BR: 14mcd) and viewing angle (H100CHDL: 45° versus PCH125-BR: 60°). Both parts share identical color (red, 635nm), lens size (3mm, T-1), lens style (round with domed top), and mounting type (through-hole, right-angle).

Q: Are both parts RoHS compliant?

A: Yes, both the PCH125-BR and H100CHDL are ROHS3 compliant, meeting current environmental standards for electronic component manufacturing.

Q: What is the packaging difference between these parts?

A: The PCH125-BR packaging is listed as standard through-hole format. The H100CHDL is supplied in tray packaging. Both parts use identical through-hole, right-angle mounting configuration.

Q: Why is the PCH125-BR classified as obsolete?

A: The PCH125-BR is an obsolete product from Visual Communications Company. The H100CHDL from Bivar Inc. is an active product with current manufacturing support, making it the recommended choice for new designs and ongoing production requirements.

Q: Can the narrower viewing angle of the H100CHDL affect application performance?

A: The H100CHDL has a 45° viewing angle compared to the PCH125-BR's 60° viewing angle. Applications requiring wide-angle illumination must evaluate whether the narrower cone of light is acceptable for the intended circuit board indicator function.
