Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD5WATMSD is determined by strict alignment across the following critical parameters:

Mandatory Matching Criteria:

• Series family: LM561B
• Color specification: White, Neutral
• Correlated color temperature: 4000K
• CRI (Color Rendering Index): 80
• Viewing angle: 120°
• Package type: 4-SMD configuration
• Supplier device package: 5630
• Physical dimensions: 5.00mm × 3.00mm
• Mounting type: Surface Mount

Electrical Operating Parameters:

• Forward voltage (Typ): 2.95V
• Test current: 65mA
• Flux output @ 25°C, 65mA: 34 lm (tolerance range 32–36 lm)

Compliance & Environmental:

• RoHS Compliant status
• MSL Rating: 2A (4 Weeks)

The substitute part SPMWHT541MP5WAT0S5 meets all mandatory matching criteria. Variations in maximum current rating (180mA vs. 150mA), thermal resistance (15°C/W vs. 16°C/W), height (0.80mm vs. 0.90mm), and product status (Active vs. Not For New Designs) do not disqualify substitution when electrical and optical performance remain within specification.

Parameter Comparison

Engineering Selection Recommendations

SPMWHT541MP5WAT0S5 as Primary Substitute:

The SPMWHT541MP5WAT0S5 is the direct equivalent substitute for SPMWHT541MD5WATMSD. Both components share identical base product number (SPMWHT541), series family (LM561B), optical specifications (4000K, 80 CRI, 120° viewing angle), and electrical operating parameters (2.95V Vf, 65mA test current, 34–35 lm output).

The substitute part carries Active product status, indicating continued manufacturer support and availability for new designs. This status transition provides supply chain assurance and long-term component availability.

Electrical performance improvements in the substitute include higher maximum current rating (180mA vs. 150mA) and improved thermal resistance (15°C/W vs. 16°C/W). These enhancements do not alter compatibility in applications designed for the original part's 65mA test current specification.

Physical profile differences are minimal: the substitute exhibits reduced maximum height (0.80mm vs. 0.90mm), which provides design flexibility for space-constrained applications. Both components maintain identical footprint dimensions (5.00mm × 3.00mm) and mounting compatibility.

Both parts maintain RoHS Compliance and identical MSL ratings (2A, 4 Weeks), ensuring equivalent environmental and handling requirements.

Packaging Consideration:

The original part is supplied in bulk packaging format. The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes. This packaging difference does not affect component performance or electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAT0S5 directly replace SPMWHT541MD5WATMSD in existing designs?

A: Yes. Both components share identical electrical operating parameters (2.95V forward voltage, 65mA test current), optical specifications (4000K, 80 CRI, 120° viewing angle), and physical footprint (5.00mm × 3.00mm). The substitute is electrically and mechanically compatible for direct substitution.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This designation indicates the SPMWHT541MD5WATMSD remains available but is no longer recommended for new product development. The substitute SPMWHT541MP5WAT0S5 carries Active status, confirming ongoing manufacturer support and suitability for new designs.

Q: Are there differences in thermal performance between these parts?

A: The substitute exhibits improved thermal resistance (15°C/W vs. 16°C/W) and reduced maximum height (0.80mm vs. 0.90mm). These improvements enhance thermal management in space-constrained applications but do not affect compatibility at the specified 65mA test current.

Q: Does the higher maximum current rating of the substitute affect compatibility?

A: No. The substitute's maximum current rating (180mA vs. 150mA) provides additional operational headroom but does not alter performance at the standard 65mA test current. Applications designed for the original part's current specification remain fully compatible.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for manual assembly and small-volume applications. Tape & Reel (TR) format is optimized for automated pick-and-place assembly in high-volume manufacturing. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Are RoHS and MSL ratings identical between these parts?

A: Yes. Both components are RoHS Compliant and carry identical MSL ratings (2A, 4 Weeks), ensuring equivalent environmental compliance and moisture sensitivity handling requirements.

Q: What is the flux output difference between these parts?

A: At 25°C and 65mA test current, the original part delivers 34 lm (tolerance 32–36 lm) and the substitute delivers 35 lm (tolerance 34–36 lm). Both values fall within acceptable tolerance ranges for neutral white 4000K LED applications. The substitute exhibits marginally higher efficiency (182 lm/W vs. 177 lm/W).

Q: Are there any lead configuration differences?

A: The original part features "Flat Lead Exposed Pad" configuration. The substitute features "Flat Leads" configuration. Both are 4-SMD packages with identical footprint dimensions and mounting compatibility. Lead configuration differences do not affect PCB assembly or electrical performance.
