• Test Current: 65mA
• Maximum Current: 180mA
• Luminous Flux @ 25°C: 34lm (33lm ~ 35lm range)
• Lumens per Watt: 177 lm/W
• Color Temperature (CCT): 5000K
• Color Rendering Index (CRI): 80

Mechanical Parameters (Must Match):

• Package / Case: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Dimensions: 5.00mm L x 3.00mm W
• Height (Seated, Max): 0.80mm
• Viewing Angle: 120°
• Thermal Resistance: 15°C/W

Compliance Parameters (Must Match):

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: 2A (4 Weeks)
• ECCN: EAR99
• HTSUS: 8541.41.0000

Variable Parameter (Allows Substitution):

• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Cut Tape & Digi-Reel® (CT & Digi-Reel®)

All three substitute parts maintain identical electrical and mechanical specifications. Substitution is valid across different packaging formats while maintaining full functional and compliance equivalence.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers are functionally equivalent and interchangeable at the electrical and mechanical level. Selection between SPMWHT541MP5WARNS4 and its substitutes should be based on the following criteria:

Packaging Format Requirements:

• SPMWHT541MP5WARNS4 and SPMWHT541MP5WARMS4 are supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations.
• SPMWHT541MP5WAR0S4 is supplied in Cut Tape (CT) & Digi-Reel® format, offering flexibility for mixed-volume production environments.
• SPMWHT541MP5WARKS4 is supplied in Cut Tape (CT) format, appropriate for lower-volume or manual assembly processes.

Compliance Considerations:

• SPMWHT541MP5WARNS4 carries RoHS Compliant certification.
• SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, and SPMWHT541MP5WARMS4 carry ROHS3 Compliant certification, representing the current RoHS 3 directive compliance standard.

Inventory Availability:

• SPMWHT541MP5WAR0S4 offers the highest inventory level (500,300 pieces), providing supply chain security for large-scale production.
• SPMWHT541MP5WARKS4 provides moderate availability (73,313 pieces).
• SPMWHT541MP5WARMS4 and SPMWHT541MP5WARNS4 have lower inventory levels (19,382 and 793 pieces respectively).

All parts maintain identical thermal, optical, and electrical performance characteristics. Selection should prioritize packaging format alignment with manufacturing equipment capabilities and compliance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAR0S4 be used as a direct replacement for SPMWHT541MP5WARNS4?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: SPMWHT541MP5WARNS4 uses Tape & Reel (TR) while SPMWHT541MP5WAR0S4 uses Cut Tape (CT) & Digi-Reel®. Direct substitution is valid if your assembly equipment supports the alternative packaging format.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents compliance with the current RoHS 3 directive (2015/863/EU), which includes additional restricted substances beyond the original RoHS standard. SPMWHT541MP5WARNS4 carries the earlier RoHS Compliant certification, while the three substitute parts carry ROHS3 Compliant certification. Both are valid for most applications; ROHS3 Compliant parts meet stricter environmental standards.

Q: Are the optical characteristics identical across all four part numbers?

A: Yes. All four parts deliver 34lm luminous flux at 25°C with 65mA test current, 177 lm/W efficiency, 5000K color temperature, 80 CRI, and 120° viewing angle. Optical performance is identical regardless of packaging format.

Q: Can I mix packaging formats in a single production run?

A: Mixing packaging formats is not recommended within a single automated assembly process, as different formats require different feeder configurations and handling procedures. However, the parts are electrically and mechanically interchangeable for final application performance.

Q: What is the thermal resistance specification and why does it matter?

A: The thermal resistance of 15°C/W indicates the temperature rise per watt of power dissipation. At 65mA and 2.95V, the LED dissipates approximately 0.19W. This specification is critical for thermal management design and ensures the LED operates within safe junction temperature limits across the specified operating range.

Q: Are all four parts suitable for high-volume production?

A: SPMWHT541MP5WAR0S4 is optimal for high-volume production due to its highest inventory availability (500,300 pieces) and flexible packaging format. SPMWHT541MP5WARKS4 and SPMWHT541MP5WARMS4 support high-volume production with adequate inventory. SPMWHT541MP5WARNS4 has limited inventory (793 pieces) and is suitable for lower-volume applications or as a secondary source.

Q: What is the Moisture Sensitivity Level (MSL) 2A specification?

A: MSL 2A indicates the component can be stored in dry conditions for up to 4 weeks before soldering. After this period, the component must be baked according to IPC-A-610 standards before assembly to prevent moisture-induced defects during reflow soldering.
