Substitute Part Grouping Explanation

Substitution eligibility for SPMWHT541MH7WATMSB is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Forward voltage (2.95V typical), test current (65mA), maximum current (180mA), and color rendering index (80) must remain constant across all substitute parts.

Optical Characteristics: White color output and 120° viewing angle are mandatory for functional equivalence.

Mechanical Specifications: All substitute parts maintain identical package configuration (4-SMD, Flat Leads), supplier device package designation (5630), physical dimensions (5.00mm x 3.00mm), and maximum seated height (0.80mm).

Thermal Properties: Thermal resistance of 15°C/W is preserved across all alternatives.

Compliance & Environmental: RoHS compliance, MSL rating (2A, 4 Weeks), ECCN (EAR99), and HTSUS code (8541.41.0000) are consistent across all listed substitutes.

The primary distinction among substitute parts is packaging format (Tape & Reel) and product status (Active vs. Obsolete), with no variation in electrical or mechanical performance parameters.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAS0S4 directly replace SPMWHT541MH7WATMSB in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The primary difference is packaging format (Tape & Reel vs. Bulk) and product status (Active vs. Obsolete). Circuit-level compatibility is complete.

Q: What is the significance of the different suffix codes (WAS0S4, WASKS4, WASMS4, WASNS4, etc.) in the substitute part numbers?

A: The suffix codes represent packaging and manufacturing variants within the LM561B Plus series. All variants listed maintain identical electrical and mechanical specifications. Suffix variations do not affect functional performance or compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry RoHS compliance status identical to the main part, with matching ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

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

A: The MSL rating is 2A (4 Weeks) for all parts where specified. This indicates the maximum time the component can be exposed to ambient conditions (30°C, 60% RH) before requiring baking prior to reflow soldering.

Q: Can I mix different substitute part numbers in the same production batch?

A: Yes. All substitute parts are parametrically equivalent and interchangeable. However, standard manufacturing practice recommends maintaining consistent part numbers within a single production lot for traceability and quality documentation purposes.

Q: What is the thermal resistance specification, and why is it important?

A: Thermal resistance is specified at 15°C/W for all parts. This parameter defines the temperature rise per unit of power dissipation and is critical for thermal management calculations in LED circuit design. All substitutes maintain identical thermal performance.

Q: Is the 120° viewing angle specification consistent across all substitute parts?

A: Yes. All substitute parts maintain 120° viewing angle specification, ensuring identical optical performance and light distribution characteristics in end-use applications.
