Key Parameters

Substitute Part Grouping Explanation

Substitution of the IN-B101FCH is determined by the following critical parameters:

Configuration Requirements: The substitute must maintain common anode configuration to ensure direct pin compatibility with existing circuit designs.

Optical Specifications: Wavelength characteristics (dominant and peak wavelengths for red, green, and blue channels) must remain within acceptable ranges for color consistency. The IN-B101FCH operates at 621nm red, 531nm green, and 470nm blue dominant wavelengths.

Electrical Characteristics: Forward voltage (Vf) and test current specifications define the LED's operational envelope. The IN-B101FCH requires 2.4V red, 3.4V green, and 3.4V blue at 10mA test current per channel.

Package and Mechanical Compatibility: Surface mount package type, footprint dimensions (1.00mm x 1.00mm), and maximum height (0.75mm) must accommodate existing PCB layouts and assembly processes.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are mandatory for production continuity.

The identified substitute IN-S11TET5R2G2B meets these core substitution criteria while operating as an active product with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The IN-B101FCH is classified as obsolete, making the IN-S11TET5R2G2B the appropriate selection for new production and design implementations. The substitute maintains active product status with current manufacturing support from Inolux.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement across regulated markets.

Electrical Parameter Differences: The IN-S11TET5R2G2B operates at reduced forward voltages (1.6V red, 2.5V green, 2.6V blue) and lower test currents (5mA red, 2mA green, 2mA blue) compared to the IN-B101FCH. Circuit designs must accommodate these electrical differences through appropriate current-limiting resistor recalculation.

Luminous Intensity Variation: The substitute delivers approximately 48% of the red intensity, 44% of the green intensity, and 41% of the blue intensity relative to the main part. Applications requiring specific brightness levels must evaluate this reduction against functional requirements.

Mechanical Compatibility: The substitute footprint is 0.05mm smaller in each dimension (0.95mm versus 1.00mm), remaining within typical PCB layout tolerances for 1010 metric packages. Maximum height remains identical at 0.75mm.

Optical Characteristics: Dominant wavelengths remain within 1nm variance across all color channels, ensuring color consistency for RGB indication applications.

Frequently Asked Questions (FAQ)

Q: Can IN-S11TET5R2G2B directly replace IN-B101FCH without circuit modifications?

A: Pin configuration and common anode topology are identical, enabling direct PCB footprint compatibility. However, the reduced forward voltages and test currents require recalculation of current-limiting resistors in the driving circuit. Direct electrical substitution without resistor adjustment will result in reduced LED brightness.

Q: What is the impact of the 20nm viewing angle reduction from 140° to 120°?

A: The substitute provides a narrower viewing cone. Applications requiring wide-angle RGB indication across multiple viewing positions must evaluate whether 120° viewing angle satisfies functional requirements.

Q: Are the wavelength differences significant for color matching?

A: Dominant wavelength variations are minimal (1nm or less across all channels). Peak wavelengths remain identical. For standard RGB indication applications, color perception differences are negligible.

Q: What packaging differences exist between these parts?

A: The IN-B101FCH uses 0404 (1010 Metric) SMD packaging, while the IN-S11TET5R2G2B specifies 4-SMD, No Lead (1010) packaging. Both are surface mount 1010 metric packages with identical height. The 0.05mm footprint size difference is within standard PCB manufacturing tolerances.

Q: Is the reduced luminous intensity a concern for my application?

A: The substitute delivers approximately 40-48% of the original brightness across color channels. Applications requiring specific minimum brightness levels must evaluate whether this reduction meets functional specifications. Brightness perception depends on viewing distance, ambient lighting, and application context.

Q: What is the moisture sensitivity impact?

A: Both parts maintain identical MSL 2A (4 Weeks) ratings, requiring identical storage and handling procedures. No additional moisture control measures are necessary when substituting.

Q: Can I use IN-S11TET5R2G2B in existing inventory of IN-B101FCH applications?

A: Yes, provided circuit design accommodates the electrical parameter differences. Resistor values must be recalculated for the lower forward voltages and test currents. Brightness reduction must be acceptable for the application.
