Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain complete parametric equivalence to SPMWHT541MH7WARMSB across electrical, mechanical, and compliance specifications. Selection among substitute options is determined by the following factors:

Product Status Consideration: The main part SPMWHT541MH7WARMSB carries obsolete status. All substitute parts (SPMWHT541MP5WAS0S4, SPMWHT541MP5WAS0S5, SPMWHT541MP5WASKS4, SPMWHT541MP5WASKS5, SPMWHT541MP5WASMS4, SPMWHT541MP5WASMS5, SPMWHT541MP5WASNS4, SPMWHT541MP5WASNS5) are classified as active, ensuring long-term availability and supply chain continuity.

Packaging Configuration: The original part is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) configuration, which is standard for automated assembly operations and high-volume production environments.

Inventory Availability: Substitute parts demonstrate varying inventory levels. SPMWHT541MP5WASMS4 and SPMWHT541MP5WASMS5 offer the highest inventory positions (25,748 and 25,826 units respectively), followed by SPMWHT541MP5WAS0S4 and SPMWHT541MP5WAS0S5 (25,612 and 25,100 units respectively).

Compliance Certification: All substitute parts maintain RoHS compliance and EAR99 ECCN classification, consistent with the original part. Moisture Sensitivity Level (MSL) is specified as 2A (4 Weeks) for SPMWHT541MP5WAS0S4, SPMWHT541MP5WAS0S5, SPMWHT541MP5WASMS4, and SPMWHT541MP5WASMS5. MSL data is not provided for SPMWHT541MP5WASKS4, SPMWHT541MP5WASKS5, SPMWHT541MP5WASNS4, and SPMWHT541MP5WASNS5.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAS0S4 be used as a direct replacement for SPMWHT541MH7WARMSB?

A: Yes. SPMWHT541MP5WAS0S4 is a parametric equivalent with identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current), mechanical configuration (5630 package, 4-SMD flat leads, 5.00mm × 3.00mm dimensions), and compliance certifications (RoHS compliant, EAR99 ECCN). The primary difference is packaging format: SPMWHT541MP5WAS0S4 is supplied in Tape & Reel configuration versus bulk packaging for the original part.

Q: What is the difference between SPMWHT541MP5WAS0S4 and SPMWHT541MP5WASMS4?

A: Both parts are parametrically identical across all electrical, mechanical, and compliance parameters. The designations reflect different manufacturing or distribution batches within the Samsung LM561B Plus series. Selection between these parts should be based on inventory availability and supply chain requirements.

Q: Are all substitute parts suitable for automated pick-and-place assembly?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, which is the standard format for automated surface mount assembly equipment. The 5630 package configuration and 4-SMD flat lead design are compatible with standard SMT placement machinery.

Q: Does the Tape & Reel packaging affect electrical performance?

A: No. Tape & Reel packaging is a distribution and handling format only. It does not alter the electrical characteristics, thermal properties, or performance of the LED component. All substitute parts deliver identical forward voltage (2.95V), test current (65mA), viewing angle (120°), and color rendering index (80).

Q: What is the significance of the MSL (Moisture Sensitivity Level) rating?

A: MSL 2A (4 Weeks) indicates the component can be exposed to ambient conditions of 30°C and 85% relative humidity for up to 4 weeks without requiring baking prior to reflow soldering. This specification applies to SPMWHT541MP5WAS0S4, SPMWHT541MP5WAS0S5, SPMWHT541MP5WASMS4, and SPMWHT541MP5WASMS5. For parts without specified MSL data, consult Samsung Semiconductor technical documentation.

Q: Can I mix substitute parts from different part numbers in the same production run?

A: All substitute parts maintain identical electrical and mechanical specifications, allowing interchangeability within the same circuit design and PCB layout. However, procurement and inventory management practices should maintain consistency within individual production batches to ensure traceability and compliance documentation.

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

A: The thermal resistance of 15°C/W indicates the temperature rise per watt of power dissipation within the package. At 65mA test current and 2.95V forward voltage (approximately 0.19W), this specification ensures predictable thermal behavior in the application circuit. This parameter is identical across all substitute parts.
