Key Parameters

Substitute Part Grouping Explanation

The HSMR-C110 qualifies as a direct substitute based on the following alignment of critical parameters:

Mechanical Compatibility: Both parts share identical mounting type (Surface Mount, Right Angle), package configuration (2-SMD, No Lead), physical dimensions (3.20mm L x 1.50mm W), maximum height (1.00mm), and lens size (2.00mm x 1.00mm).

Optical Compatibility: Both parts feature diffused lens transparency, blue color, and identical viewing angle (130°).

Electrical Compatibility: Both parts operate at 20mA test current and share the same 2-SMD, No Lead package footprint, enabling direct PCB-level substitution.

Regulatory Alignment: Both parts carry identical REACH Status (REACH Unaffected) and ECCN classification (EAR99), with matching HTSUS codes (8541.41.0000).

Key Differences: The HSMR-C110 operates at a lower forward voltage (3.4V vs. 3.8V), features a higher millicandela rating (60mcd vs. 6.5mcd), and has an active product status with RoHS3 compliance and improved availability (20,400 pcs vs. 849 pcs).

Parameter Comparison

Engineering Selection Recommendations

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

Product Status: The HSMR-C110 maintains active product status with ongoing manufacturer support, whereas the HSMB-C110 is obsolete and subject to discontinuation.

Regulatory Compliance: The HSMR-C110 carries RoHS3 compliance certification, meeting current environmental and regulatory requirements. Both parts maintain identical REACH and ECCN classifications.

Packaging Options: The HSMR-C110 is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both manual and automated assembly processes.

Electrical Performance: The HSMR-C110 operates at a lower forward voltage (3.4V vs. 3.8V), reducing power consumption in indication circuits. The higher millicandela rating (60mcd vs. 6.5mcd) provides enhanced brightness for visual indication applications.

Frequently Asked Questions (FAQ)

Q: Can the HSMR-C110 be used as a direct replacement for the HSMB-C110 on existing PCBs?

A: Yes. Both parts share identical mechanical footprints (3.20mm L x 1.50mm W, 1.00mm height), package configuration (2-SMD, No Lead), and mounting type (Surface Mount, Right Angle). No PCB redesign is required.

Q: What are the differences in wavelength between these parts?

A: The HSMB-C110 has a dominant wavelength of 466nm, while the HSMR-C110 has a dominant wavelength of 473nm. Both are blue LEDs within the visible spectrum. The wavelength difference reflects different phosphor formulations but maintains visual blue color perception in indication applications.

Q: How does the forward voltage difference affect circuit design?

A: The HSMR-C110 operates at 3.4V compared to the HSMB-C110 at 3.8V. This 0.4V reduction lowers power dissipation in series resistor networks and may improve efficiency in battery-powered applications. Existing current-limiting resistor values remain compatible at the 20mA test current.

Q: What is the significance of the millicandela rating difference?

A: The HSMR-C110 provides 60mcd brightness compared to 6.5mcd for the HSMB-C110. This ninefold increase in luminous intensity results in brighter visual indication. Applications requiring specific brightness levels should account for this difference in circuit design.

Q: Are there packaging considerations for procurement?

A: The HSMR-C110 is available in Cut Tape (CT) and Digi-Reel® packaging, supporting both manual pick-and-place and automated assembly processes. The HSMB-C110 packaging format is not specified. Confirm packaging requirements with your assembly process before procurement.

Q: Does the RoHS3 compliance of the HSMR-C110 affect compatibility?

A: RoHS3 compliance of the HSMR-C110 indicates adherence to current environmental regulations and is compatible with modern manufacturing and end-use requirements. This represents an improvement over the obsolete HSMB-C110 and aligns with current industry standards.

Q: What is the moisture sensitivity level for both parts?

A: Both the HSMB-C110 and HSMR-C110 carry an MSL rating of 2A (4 Weeks), indicating identical moisture sensitivity handling requirements. Standard moisture control procedures during storage and assembly apply to both parts.
