Substitute Part Grouping Explanation

The HSMR-C110 is identified as a manufacturer-recommended substitute for the HSMB-C112. Substitution eligibility is determined by the following critical parameters:

• Package compatibility: Both parts use 2-SMD, No Lead surface mount configuration with identical mounting type (right angle)
• Physical dimensions: Both maintain 3.20mm length and 1.00mm maximum height, ensuring PCB layout compatibility
• Lens style and size: Both feature rectangle with domed top lens configuration at 2.00mm x 1.00mm
• Viewing angle: Both provide 130° viewing angle for equivalent light distribution
• Wavelength family: Both are blue LEDs within the 460-475nm dominant wavelength range
• Regulatory compliance: Both maintain REACH Unaffected status and EAR99 ECCN classification

The HSMR-C110 represents an active product with enhanced specifications including higher brightness (60mcd vs. 3.1mcd), lower forward voltage (3.4V vs. 4V), and diffused lens technology, making it suitable for applications where the HSMB-C112 is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The HSMR-C110 is the manufacturer-recommended substitute for the obsolete HSMB-C112. Selection of the HSMR-C110 is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• RoHS3 compliance certification providing regulatory assurance for new designs
• Identical package footprint and mounting configuration enabling direct PCB layout compatibility
• Equivalent MSL rating (2A, 4 Weeks) maintaining identical moisture handling requirements
• Maintained regulatory classifications (REACH Unaffected, EAR99) ensuring no compliance barriers

The HSMR-C110 operates at lower forward voltage (3.4V vs. 4V) and higher brightness (60mcd vs. 3.1mcd), requiring circuit design verification to confirm compatibility with existing current-limiting resistor values and brightness requirements. The diffused lens and white lens color of the HSMR-C110 produce different light distribution characteristics compared to the clear lens of the HSMB-C112.

Frequently Asked Questions (FAQ)

Q: Can the HSMR-C110 be used as a direct drop-in replacement for the HSMB-C112?

A: The HSMR-C110 shares identical package, mounting type, and physical dimensions with the HSMB-C112, enabling PCB-level compatibility. However, circuit design verification is required due to differences in forward voltage (3.4V vs. 4V) and brightness (60mcd vs. 3.1mcd). Existing current-limiting resistor values must be recalculated to maintain proper LED operation.

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

A: The primary differences are forward voltage (HSMR-C110 operates at 3.4V vs. HSMB-C112 at 4V), brightness rating (HSMR-C110 is 60mcd vs. HSMB-C112 at 3.1mcd), lens transparency (HSMR-C110 is diffused vs. HSMB-C112 is clear), and dominant wavelength (HSMR-C110 is 473nm vs. HSMB-C112 at 462nm). Both maintain 130° viewing angle and identical package configuration.

Q: Are there any compliance or regulatory differences?

A: Both parts maintain identical regulatory status: REACH Unaffected, EAR99 ECCN classification, and 2A MSL rating. The HSMR-C110 carries RoHS3 compliance certification, providing additional regulatory assurance for new product designs.

Q: What is the width difference between these parts?

A: The HSMB-C112 measures 3.20mm L x 1.00mm W, while the HSMR-C110 measures 3.20mm L x 1.50mm W. The 0.50mm width increase must be verified against PCB layout constraints to ensure no clearance conflicts with adjacent components.

Q: How do the lens characteristics affect application suitability?

A: The HSMB-C112 features a clear colorless lens providing direct light transmission at 462nm wavelength. The HSMR-C110 features a diffused white lens at 473nm wavelength, producing broader light distribution and different color perception. Application requirements for light intensity, color accuracy, and viewing angle distribution must be evaluated against these differences.
