Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH1228FD5WAR0SC is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Color and CCT: White, Cool 5000K
• Forward Voltage (Typ): 3.1V
• Test Current: 150mA
• Maximum Current: 160mA
• Luminous Flux @ 25°C: 65lm (63–67lm range)
• Lumens/Watt: 140 lm/W
• CRI: 80

Mechanical Parameters (Must Match):

• Package / Case: 1113 (2835 Metric)
• Physical Dimensions: 3.50mm × 2.80mm
• Height - Seated (Max): 0.75mm
• Mounting Type: Surface Mount
• Thermal Resistance: 25°C/W

Lifecycle & Compliance Parameters (May Vary):

• Product Status: Active or Not For New Designs
• RoHS Certification: RoHS Compliant or ROHS3 Compliant
• MSL Rating: 2A (4 Weeks)

The identified substitutes SPMWH1228FD5WAR0S3 and SPMWH1228FD5WARMS3 maintain complete electrical and mechanical equivalence to the primary part. Differences exist only in product lifecycle status and RoHS certification level, which do not affect functional performance or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (SPMWH1228FD5WAR0SC): Select the primary part for new designs and applications requiring Active product status. This part carries RoHS Compliant certification and maintains full manufacturer support. Current inventory of 984 units supports production requirements.

Substitute Part Selection (SPMWH1228FD5WAR0S3): The SPMWH1228FD5WAR0S3 is electrically and mechanically identical to the primary part but carries Not For New Designs status. This part holds ROHS3 Compliant certification. Use this substitute only when the primary part is unavailable and existing designs require component replacement. Higher inventory availability (1732 units) may support urgent fulfillment needs.

Substitute Part Selection (SPMWH1228FD5WARMS3): The SPMWH1228FD5WARMS3 is electrically and mechanically identical to the primary part and carries Not For New Designs status with RoHS Compliant certification. Use this substitute only when the primary part is unavailable and existing designs require component replacement. Inventory of 1063 units is available.

Compliance Considerations: All three parts meet EAR99 export classification and HTSUS code 8541.41.0000. RoHS compliance differs between parts; verify compliance requirements for your specific application before selection. MSL rating of 2A (4 Weeks) applies uniformly across all parts.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1228FD5WAR0S3 and SPMWH1228FD5WARMS3 be used interchangeably with SPMWH1228FD5WAR0SC in existing designs?

A: Yes. All three parts share identical electrical parameters (3.1V forward voltage, 150mA test current, 65lm flux, 140 lm/W efficiency, 80 CRI) and mechanical specifications (2835 package, 3.50 × 2.80mm dimensions, 0.75mm height, 120° viewing angle). Direct substitution is supported at the circuit and PCB assembly level.

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

A: Both certifications indicate compliance with Restriction of Hazardous Substances directives. ROHS3 represents a more recent certification standard. For applications with specific regulatory requirements, verify which certification level is mandated before part selection.

Q: Why are SPMWH1228FD5WAR0S3 and SPMWH1228FD5WARMS3 marked "Not For New Designs"?

A: This status indicates the parts are in mature or end-of-life phases of their product lifecycle. They remain available for replacement and repair of existing designs but are not recommended for new product development. The primary part SPMWH1228FD5WAR0SC carries Active status and is the preferred choice for new designs.

Q: Are there any thermal or performance differences between the three parts?

A: No. All three parts specify identical thermal resistance (25°C/W), luminous flux (65lm at 25°C), and efficiency (140 lm/W). Thermal and optical performance are equivalent across all substitutes.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 2A (4 Weeks) indicates the part can be exposed to ambient conditions (30°C, 60% RH) for up to 4 weeks before soldering. All three parts carry this identical rating. Proper storage and handling procedures must be followed to maintain component reliability.

Q: Can these parts be used in applications requiring higher current than 150mA?

A: The maximum rated current is 160mA across all three parts. Operation above this limit voids the electrical specifications and may cause premature failure. Design circuits to operate at or below the 150mA test current for optimal performance and reliability.

Q: Are there any package or footprint differences between these parts?

A: No. All three parts use the 1113 (2835 Metric) package with identical physical dimensions (3.50 × 2.80mm) and seated height (0.75mm maximum). PCB footprints and assembly processes are identical.
