Engineering Selection Recommendations

The SPMWHT541MH7WAWMSB is classified as obsolete and should be replaced with an active equivalent from the LM561B Plus series. All identified substitute parts maintain complete electrical, optical, and mechanical equivalence to the original component.

Selection Criteria Based on Product Status and Compliance:

All substitute parts are classified as Active products, ensuring ongoing availability and manufacturer support. All substitutes maintain RoHS Compliance and identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory equivalence.

Packaging Consideration:

The main part SPMWHT541MH7WAWMSB is supplied in bulk packaging format. All substitute parts are supplied in Tape & Reel (TR) format, which is the standard packaging for production environments. This packaging difference does not affect electrical or mechanical compatibility but may require adjustment to procurement and assembly processes.

Available Substitute Options:

SPMWHT541MP5WAS0S4: 25,612 units in stock
SPMWHT541MP5WAS0S5: 25,100 units in stock
SPMWHT541MP5WASKS4: 1,012 units in stock

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAS0S4 directly replace SPMWHT541MH7WAWMSB in existing designs?

A: Yes. SPMWHT541MP5WAS0S4 is a parametric equivalent with identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current), optical characteristics (white color, 120° viewing angle, CRI 80), and mechanical dimensions (5630 package, 5.00mm x 3.00mm, 0.80mm height). The only difference is packaging format (Tape & Reel vs. bulk), which does not affect circuit performance.

Q: What is the difference between the various substitute part numbers (WAS0S4, WASKS4, WASMS4, WASNS4)?

A: The provided data does not specify the technical meaning of these suffix variations. All parts maintain identical electrical, optical, and mechanical parameters. Differences may relate to manufacturing lot codes, date codes, or internal Samsung classification systems. For clarification on suffix designations, contact Samsung Semiconductor directly.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry RoHS Compliant status, matching the compliance level of the original SPMWHT541MH7WAWMSB component.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: The specified MSL is 2A (4 Weeks) for all parts where this parameter is documented. This indicates the component can be exposed to ambient conditions for up to 4 weeks before soldering without requiring baking.

Q: Can I use substitute parts with different packaging (Tape & Reel instead of bulk)?

A: Yes. Tape & Reel packaging is compatible with automated assembly equipment and is the standard format for production environments. The component itself is identical; only the delivery format differs. Ensure your assembly process supports Tape & Reel input.

Q: What is the thermal resistance specification?

A: All parts specify 15°C/W thermal resistance of package. This parameter determines heat dissipation characteristics and is identical across all equivalent parts.

Q: Are there any electrical parameter differences among the substitute options?

A: No. All substitute parts maintain identical electrical specifications: 2.95V typical forward voltage, 65mA test current, and 180mA maximum current rating.
