Substitute Part Grouping Explanation

Substitution of the obsolete SPMWHF32AMD5XAV0S0 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Series: LM301B (identical)
Color: White, Warm (identical)
CCT: 3000K (identical)
Flux @ 25°C, Test Current: 36 lm (34–38 lm range) (identical)
Test Current: 65 mA (identical)
Forward Voltage (Vf) Typical: 2.75 V (identical)
Lumens per Watt: 201 lm/W (identical)
CRI: 80 (identical)
Viewing Angle: 120° (identical)

Mechanical Equivalence Criteria:

Package / Case: 1212 (3030 Metric) (identical)
Size / Dimension: 3.00 × 3.00 mm (identical)
Height – Seated (Max): 0.85 mm (identical)
Thermal Resistance: 7.5 °C/W (identical)
Mounting Type: Surface Mount (identical)

Allowable Variation:

Maximum Current: The main part specifies 180 mA maximum; substitute parts specify 200 mA maximum. This represents an increase in current handling capability and does not restrict substitution.
Moisture Sensitivity Level (MSL): The main part specifies MSL 1 (Unlimited); substitute parts specify MSL 2A (4 Weeks). This represents a change in moisture handling requirements during storage and handling.
Product Status: The main part is Obsolete; substitute parts are Active.
Packaging: The main part specifies no packaging designation; substitute parts specify Tape & Reel (TR).

All three substitute parts meet the electrical and mechanical equivalence criteria and are direct parametric equivalents suitable for replacement in applications originally designed for SPMWHF32AMD5XAV0S0.

Engineering Selection Recommendations

Primary Substitute: SPMWHD32AMD5XAV0S0

SPMWHD32AMD5XAV0S0 is the recommended substitute for SPMWHF32AMD5XAV0S0. This part maintains complete electrical and mechanical equivalence across all critical parameters. The part is currently Active in product status, ensuring long-term availability and supply chain continuity. Inventory availability is substantial at 43,344 pieces. The increase in maximum current rating from 180 mA to 200 mA provides enhanced current handling capability without affecting nominal operating specifications. Moisture Sensitivity Level 2A (4 Weeks) requires standard moisture control procedures during storage and assembly operations consistent with industry practice for surface mount components.

Secondary Substitutes: SPMWHD32AMD5XAVKS0 and SPMWHD32AMD5XAVSS0

SPMWHD32AMD5XAVKS0 and SPMWHD32AMD5XAVSS0 are functionally equivalent alternatives with identical electrical and mechanical specifications. Both parts are Active in product status. SPMWHD32AMD5XAVKS0 maintains inventory of 1,043 pieces; SPMWHD32AMD5XAVSS0 maintains inventory of 921 pieces. These parts are suitable for substitution where supply of the primary substitute is constrained. All three substitute parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications as the main part.

Frequently Asked Questions (FAQ)

Q: Can SPMWHD32AMD5XAV0S0, SPMWHD32AMD5XAVKS0, and SPMWHD32AMD5XAVSS0 be used interchangeably with SPMWHF32AMD5XAV0S0?

A: Yes. All three substitute parts are parametric equivalents with identical electrical performance (color temperature, luminous flux, forward voltage, efficiency, CRI, and viewing angle) and mechanical specifications (package dimensions, thermal resistance, and mounting type). The parts are directly interchangeable in applications designed for SPMWHF32AMD5XAV0S0.

Q: What is the difference between the main part and the substitute parts?

A: The primary differences are product status (main part is Obsolete; substitutes are Active), maximum current rating (main part: 180 mA; substitutes: 200 mA), moisture sensitivity level (main part: MSL 1; substitutes: MSL 2A), and packaging format (main part: unspecified; substitutes: Tape & Reel). All electrical and mechanical performance parameters are identical.

Q: Does the increase in maximum current from 180 mA to 200 mA affect circuit design?

A: No. The increase in maximum current rating does not affect nominal operating specifications. The test current remains 65 mA, forward voltage remains 2.75 V, and luminous flux remains 36 lm. The higher maximum current rating provides additional design margin and does not require circuit modification.

Q: What does MSL 2A (4 Weeks) mean for handling and storage?

A: MSL 2A indicates that the component can be exposed to ambient conditions of 30°C and 60% relative humidity for a maximum of 4 weeks before soldering. Standard moisture control procedures, including storage in dry-pack packaging with desiccant, are required. This is consistent with industry practice for surface mount LEDs and does not restrict substitution.

Q: Are all three substitute parts equally recommended?

A: SPMWHD32AMD5XAV0S0 is the primary recommendation due to highest inventory availability (43,344 pieces). SPMWHD32AMD5XAVKS0 and SPMWHD32AMD5XAVSS0 are suitable secondary alternatives with lower inventory levels (1,043 and 921 pieces respectively). Selection among the three should be based on supply chain availability and procurement lead time requirements.

Q: Do the substitute parts require different PCB layout or assembly procedures?

A: No. The substitute parts maintain identical package dimensions (3.00 × 3.00 mm), height (0.85 mm maximum), and mounting type (Surface Mount). PCB footprints, reflow profiles, and assembly procedures remain unchanged.

Q: What certifications and compliance standards apply to these parts?

A: All parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. No additional compliance documentation or qualification is required for substitution.
