Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH1228FD5WAVMS2 is determined by the following critical parameters:

Primary Substitution Criteria:

• Color: White, Warm (3000K)
• Package / Case: 1113 (2835 Metric)
• Mounting Type: Surface Mount
• Viewing Angle: 120°
• CRI: 80
• Test Current: 150mA
• Maximum Current: 160mA
• Thermal Resistance: 25°C/W
• Size / Dimension: 3.50mm × 2.80mm
• Height - Seated (Max): 0.75mm
• RoHS Status: RoHS Compliant
• MSL: 2A (4 Weeks)

Secondary Compatibility Parameters (Allowable Variation):

• Forward Voltage (Vf): 3.0V to 3.1V
• Flux @ 25°C, 150mA: 54–59 lm range
• Lumens/Watt: 120–124 lm/W

Substitute parts must maintain identical mechanical compatibility, electrical operating range, and environmental compliance. Series designation may vary (LM281B, LM281B+, LM281BZ+) provided all primary criteria are met.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute (Highest Compatibility):

SPMWH1228FD5WAVMSA is the primary direct substitute for SPMWH1228FD5WAVMS2. Both parts share identical electrical specifications (3.1V Vf, 150mA test current), mechanical dimensions, and package configuration. SPMWH1228FD5WAVMSA carries Active product status, ensuring ongoing availability and manufacturing support. This part is suitable for direct replacement in existing designs without circuit modification.

Parametric Equivalents (Compatible with Minor Variations):

SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, and SPMWH3228FD5WAVMSC are parametric equivalents based on the LM281BZ+ series. These parts maintain identical mechanical compatibility, package dimensions, thermal characteristics, and environmental compliance. The forward voltage is 3.0V (versus 3.1V in the main part), which falls within acceptable operating range for 2835 metric LEDs. Lumens/Watt efficiency is improved (124 lm/W versus 120 lm/W), and flux output remains within specification (56 lm at 150mA). All three parts carry Active product status.

Compliance Verification:

All substitute parts are RoHS Compliant and carry MSL 2A (4 Weeks) rating, matching the main part's environmental specifications. ECCN and HTSUS classifications remain consistent across all parts.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1228FD5WAVMSA be used as a direct replacement for SPMWH1228FD5WAVMS2?

A: Yes. SPMWH1228FD5WAVMSA is a direct substitute with identical electrical and mechanical specifications. Both parts operate at 3.1V forward voltage, 150mA test current, and share the same 2835 metric package dimensions. The primary difference is product status: SPMWH1228FD5WAVMSA is Active, ensuring continued supply availability.

Q: What is the difference between the LM281B and LM281BZ+ series?

A: The LM281B and LM281BZ+ series differ in forward voltage specification. LM281B operates at 3.1V typical, while LM281BZ+ operates at 3.0V typical. Both series maintain identical color temperature (3000K), CRI (80), viewing angle (120°), and package configuration (1113/2835 metric). The 0.1V difference is within normal LED operating tolerance and does not affect circuit compatibility in standard applications.

Q: Are the parametric equivalents (SPMWH3228 series) suitable for existing PCB designs?

A: Yes. The SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, and SPMWH3228FD5WAVMSC parts maintain identical mechanical dimensions (3.50mm × 2.80mm), height (0.75mm maximum), and thermal resistance (25°C/W) as the main part. PCB footprints and thermal management designs require no modification. The 0.1V lower forward voltage may result in slightly increased current draw in constant-voltage circuits; verify circuit design accommodates 160mA maximum current rating.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All substitute parts listed (SPMWH1228FD5WAVMSA, SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, SPMWH3228FD5WAVMSC) are RoHS Compliant with MSL 2A (4 Weeks) rating, matching the main part's environmental specifications.

Q: Which substitute part offers the best efficiency?

A: The LM281BZ+ series parts (SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, SPMWH3228FD5WAVMSC) deliver 124 lm/W efficiency compared to 120 lm/W for the main part and 123 lm/W for SPMWH1228FD5WAVMSA. This represents a 3–4% efficiency improvement while maintaining identical color temperature, CRI, and package specifications.

Q: What is the inventory status of substitute parts?

A: SPMWH1228FD5WAVMSA: 934 pcs in stock. SPMWH3228FD5WAV0SC: 737 pcs in stock. SPMWH3228FD5WAVKSC: 877 pcs in stock. SPMWH3228FD5WAVMSC: 1096 pcs in stock. All parts are available as new original components.
