Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541ML5XAT0S0 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Series: LM561C (platform compatibility)
• Color: White, Neutral (spectral output)
• CCT: 4000K (color temperature specification)
• Package / Case: 4-SMD, Flat Leads (mechanical fit)
• Supplier Device Package: 5630 (footprint compatibility)
• Size / Dimension: 5.00mm x 3.00mm (PCB layout compatibility)
• Height - Seated (Max): 0.80mm (clearance compatibility)
• Viewing Angle: 120° (optical performance)
• CRI: 80 (color rendering specification)
• RoHS Status: RoHS Compliant (regulatory requirement)
• MSL: 2A (4 Weeks) (moisture handling requirement)

Allowable Variation Parameters:

• Forward Voltage (Typ): ±0.05V tolerance
• Flux @ 25°C, 65mA: ±2lm tolerance (32lm ~ 36lm range)
• Lumens/Watt @ 65mA: ±3 lm/W tolerance
• Maximum Current: ≥180mA (equal or higher)
• Thermal Resistance: ≤12°C/W (equal or lower)

Substitute parts must maintain identical product status (Active) and compliance certifications to ensure seamless integration into production environments.

Parameter Comparison

Engineering Selection Recommendations

SPMWHT541ML5XATMS0 qualifies as a parametric equivalent substitute for SPMWHT541ML5XAT0S0 based on the following engineering criteria:

Electrical Compatibility: The forward voltage variance of +0.05V (2.75V to 2.8V) falls within acceptable tolerance for series-connected LED applications. The luminous flux output remains within the specified range (32lm ~ 36lm at 65mA, 25°C). The efficiency reduction of 3 lm/W (190 to 187 lm/W) is within normal manufacturing variation for the LM561C platform and does not impact functional performance in standard illumination circuits.

Mechanical Compatibility: Both parts share identical 5630 package geometry, 4-SMD flat lead configuration, and 0.80mm maximum seated height. PCB footprint and assembly process compatibility are maintained without modification.

Compliance & Certification: Both parts maintain Active product status, RoHS Compliance, and identical MSL rating (2A, 4 Weeks), ensuring equivalent supply chain handling and regulatory acceptance.

Inventory Consideration: SPMWHT541ML5XATMS0 maintains significantly higher inventory availability (33,730 pcs) compared to SPMWHT541ML5XAT0S0 (909 pcs), supporting production continuity and lead time reduction.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XATMS0 be used as a direct replacement for SPMWHT541ML5XAT0S0 on existing PCB assemblies?

A: Yes. Both parts share identical mechanical specifications (5630 package, 5.00mm x 3.00mm footprint, 0.80mm height) and electrical performance within acceptable tolerances. No PCB redesign or assembly process modification is required.

Q: What is the significance of the part number suffix difference (0S0 vs MS0)?

A: The suffix variation indicates different manufacturing batches or tape reel configurations within the same LM561C series. The electrical and mechanical specifications remain equivalent across both part numbers.

Q: Is the forward voltage difference of 0.05V (2.75V vs 2.8V) significant for circuit design?

A: For series-connected LED applications, this variance is within standard design tolerance. Circuit current limiting resistors or drivers accommodate this variation. For precision constant-current applications, verify driver specifications support the 2.8V maximum forward voltage.

Q: Are both parts suitable for the same thermal management requirements?

A: Yes. Both parts have identical thermal resistance of 12°C/W and maximum current rating of 180mA. Thermal design calculations and heat dissipation strategies remain unchanged.

Q: What is the impact of the 3 lm/W efficiency difference?

A: The efficiency variance (190 lm/W vs 187 lm/W) represents approximately 1.6% reduction in power efficiency. For a 65mA test current, this translates to negligible practical difference in illumination output (both deliver 34 lumens within the 32lm ~ 36lm specification range).

Q: Do both parts require identical moisture handling procedures?

A: Yes. Both parts carry MSL rating 2A (4 Weeks), requiring identical storage conditions, reflow temperature profiles, and moisture bake-out procedures if exposed to ambient humidity beyond the 4-week limit.

Q: Can these parts be mixed in the same production batch?

A: Yes. Identical electrical performance, mechanical compatibility, and compliance certifications support mixed-part production runs without circuit or assembly modifications. Inventory management systems should track part numbers separately for traceability.
