Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H131CSRT-120 is determined by the following critical parameters that must align across candidate parts:

Mandatory Matching Parameters:

• Lens Size: 3mm, T-1 form factor
• Color: Red
• Configuration: Single LED
• Current Rating: 20mA
• Voltage Rating: 1.7V
• Wavelength - Peak: 645nm
• Millicandela Rating: 60mcd
• Viewing Angle: 30°
• Manufacturer: Bivar Inc.
• Series Compatibility: H131 base series

The H131CSRD-120 qualifies as a substitute part within the H131 series family. Both components share the same base product number (H131) and maintain electrical and optical specifications within the defined parameters. The substitute part is manufactured by the same supplier, ensuring consistency in design intent and performance characteristics.

Engineering Selection Recommendations

The H131CSRD-120 is the designated substitute for the obsolete H131CSRT-120. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The H131CSRD-120 maintains active production status with Bivar Inc., ensuring continued availability and supply chain reliability compared to the obsolete main part.

Compliance Certification: The substitute part carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Electrical and Optical Equivalence: Both parts maintain identical electrical specifications (20mA current, 1.7V voltage) and optical characteristics (645nm peak wavelength, 60mcd brightness, 30° viewing angle), ensuring functional interchangeability in circuit board indicator applications.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) classification, indicating equivalent moisture handling and storage requirements.

Trade Classification: Identical ECCN (EAR99) and HTSUS (8541.41.0000) codes confirm regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the H131CSRD-120 directly replace the H131CSRT-120 in existing designs?

A: Yes. Both parts share identical electrical ratings (20mA, 1.7V), optical specifications (645nm, 60mcd, 30° viewing angle), and physical form factor (3mm T-1). The substitute maintains functional equivalence for circuit board indicator applications.

Q: What is the primary reason for seeking a substitute?

A: The H131CSRT-120 is classified as obsolete. The H131CSRD-120 is an active production part from the same manufacturer, providing continued component availability and supply chain continuity.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified in available documentation. The substitute part is supplied in Tray packaging. Packaging format should be confirmed with the supplier for procurement and assembly requirements.

Q: Do both parts meet current environmental standards?

A: The H131CSRD-120 carries ROHS3 compliance certification. The main part's RoHS status is not specified. Both parts share MSL 1 (Unlimited) moisture sensitivity classification.

Q: Are there any export or tariff considerations?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, indicating equivalent regulatory treatment for export and tariff purposes.

Q: What are the critical parameters for confirming substitution compatibility?

A: Substitution is valid when the following parameters match: 3mm T-1 lens size, red color, single configuration, 20mA current, 1.7V voltage, 645nm wavelength, 60mcd brightness, and 30° viewing angle. All parameters align between the main part and substitute.
