Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete H131CSYD-160 is evaluated based on alignment of the following critical parameters:

• Color and Wavelength: Yellow emitting components (590nm peak wavelength) maintain optical equivalence
• Configuration: Single LED configuration
• Current Rating: Operational current specifications must support the 20mA original rating
• Viewing Angle: 40° viewing angle specification
• Lens Type: Diffused lens construction for uniform light distribution
• Voltage Rating: 2V nominal operating voltage
• Regulatory Compliance: ECCN EAR99 and HTSUS code 8541.41.0000 categorization

The substitute component XNK1LUY147D by SunLED fulfills these substitution criteria through electrical and optical parameter alignment within acceptable engineering tolerances for Circuit Board Indicator LED applications.

Parameter Comparison

Engineering Selection Recommendations

The XNK1LUY147D represents a functionally active substitute for the obsolete H131CSYD-160. Both components maintain equivalent color specifications (yellow, 590nm peak wavelength), viewing angle (40°), and regulatory classification (EAR99, HTSUS 8541.41.0000). The substitute achieves ROHS3 compliance, addressing modern manufacturing and environmental regulatory requirements.

Circuit design applications must account for the voltage rating differential (2V original versus 1.95V substitute) and current specification variance (20mA original versus 140mA maximum rating). The substitute exhibits lower brightness output (14mcd versus 30mcd), which requires evaluation within specific application luminance requirements. Physical form factor compatibility—including 2.90mm lens diameter versus 3mm T-1 original—necessitates mechanical fit assessment in board-level implementations.

Frequently Asked Questions (FAQ)

Q: Can XNK1LUY147D replace H131CSYD-160 in all applications? A: Substitution is based on electrical and optical parameter equivalence. The 1.95V versus 2V voltage rating and current specification differences require circuit design verification. The 2.90mm lens diameter versus 3mm T-1 form factor requires mechanical compatibility assessment.

Q: What are the key differences between the main part and substitute? A: Primary differences include product status (obsolete versus active), brightness output (30mcd versus 14mcd), current rating (20mA versus 140mA maximum), and physical lens diameter (3mm versus 2.90mm). Both share equivalent color emission (yellow, 590nm), viewing angle (40°), and regulatory classification.

Q: How do voltage ratings affect substitution? A: The H131CSYD-160 operates at 2V nominal, while the XNK1LUY147D is rated at 1.95V. This 0.05V differential must be evaluated within circuit design tolerance margins. Series resistor values or supply voltage specifications may require adjustment.

Q: What is the significance of the 40° viewing angle specification? A: Both components maintain a 40° viewing angle, indicating equivalent light distribution characteristics. This parameter is critical for applications where light spread uniformity is required for indicator visibility.

Q: Are there environmental or compliance differences? A: Both components carry identical Moisture Sensitivity Level (MSL 1, Unlimited) ratings. The XNK1LUY147D additionally specifies ROHS3 compliance and REACH unaffected status, aligning with current environmental and supply chain regulatory frameworks.
