HSMW-CL25 Equivalent & Substitute Parts

Part Overview

The HSMW-CL25 is a white diffused LED chip in 0603 (1608 Metric) surface mount package, designed for white LED indication applications. Specified at 2.85V forward voltage with 70mcd brightness and 120° viewing angle, this component is classified as obsolete. Due to its obsolete status and limited remaining inventory, identifying active equivalent parts is essential for design continuity and procurement reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMW-CL25 is determined by the following critical parameters:

• Package compatibility: 0603 (1608 Metric) surface mount form factor
• Color specification: White LED
• Mounting type: Surface mount
• Electrical operating range: Forward voltage and test current compatibility
• Physical dimensions: Matching footprint and height constraints
• Brightness and viewing angle: Application-dependent performance metrics

The ASMT-CW20 qualifies as a substitute based on identical package, mounting type, color, and physical dimensions. Electrical parameters differ within acceptable ranges for most applications, with higher brightness (180mcd vs. 70mcd) and wider viewing angle (150° vs. 120°) providing enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ASMT-CW20 is the active equivalent for the obsolete HSMW-CL25. Selection criteria are based on the following factors:

• Product status: ASMT-CW20 is active with 4100 units in stock, ensuring long-term availability compared to the obsolete HSMW-CL25 with limited inventory
• Compliance: Both parts maintain REACH Unaffected and EAR99 ECCN classifications
• RoHS status: ASMT-CW20 is ROHS3 Compliant, meeting current regulatory requirements
• Packaging: ASMT-CW20 is available in Cut Tape (CT) & Digi-Reel® format, supporting production workflows
• Electrical compatibility: Forward voltage difference of 0.15V (2.85V to 3V) is within typical LED circuit tolerance ranges
• Performance enhancement: Higher brightness (180mcd) and wider viewing angle (150°) provide improved optical performance without footprint changes

Frequently Asked Questions (FAQ)

Q: Can ASMT-CW20 be used as a direct replacement for HSMW-CL25 in existing designs?

A: Yes, for most applications. Both parts share identical package (0603), mounting type (surface mount), physical dimensions (1.60mm L x 0.80mm W x 0.30mm H), and color (white). Circuit designs must accommodate the 0.15V forward voltage difference and higher brightness output.

Q: What is the impact of the forward voltage difference between the two parts?

A: The ASMT-CW20 operates at 3V typical forward voltage compared to 2.85V for the HSMW-CL25. This 0.15V difference requires circuit verification to ensure proper current limiting and brightness control. Most LED indication circuits tolerate this variance.

Q: Why does ASMT-CW20 have higher brightness than HSMW-CL25?

A: The ASMT-CW20 is rated at 180mcd versus 70mcd for the HSMW-CL25. This represents improved LED die efficiency and is a performance enhancement. Applications requiring specific brightness levels must account for this difference in current limiting resistor calculations.

Q: Are there packaging differences between these parts?

A: HSMW-CL25 packaging format is not specified in available data. ASMT-CW20 is supplied in Cut Tape (CT) & Digi-Reel® format. Both parts use identical 0603 (1608 Metric) surface mount packages suitable for automated assembly.

Q: What is the moisture sensitivity difference?

A: HSMW-CL25 has MSL 3 (168 Hours) while ASMT-CW20 has MSL 2A (4 Weeks). ASMT-CW20 requires less stringent moisture control during storage and handling, reducing bake-out requirements before reflow soldering.

Q: Are both parts compliant with current regulations?

A: Both parts are REACH Unaffected and classified as EAR99 for export control. ASMT-CW20 is additionally ROHS3 Compliant, meeting current environmental and hazardous substance restrictions.
