Parameter Comparison

Engineering Selection Recommendations

SPMWHT541MD5WAVMS2 (Parametric Equivalent): This part is a direct parametric equivalent to the main part SPMWHT541MD5WAVHS2, with identical electrical performance (2.95V, 65mA, 28lm, 146 lm/W) and mechanical specifications. The primary difference is packaging format: Cut Tape (CT) & Digi-Reel® versus Tape & Reel (TR). Both parts carry RoHS Compliant certification and identical MSL ratings. However, SPMWHT541MD5WAVMS2 is classified as Obsolete, indicating limited future availability. This substitute is suitable for direct replacement in existing production runs where packaging format compatibility exists, but long-term sourcing should transition to active alternatives.

SPMWHT541MP5WAVMS4 (Similar Manufacturer Part - Recommended for New Designs): This part represents an enhanced variant within the LM561B Plus series, maintaining full electrical compatibility (2.95V, 65mA nominal) while delivering superior performance metrics. Key advantages include 14% higher luminous flux (32lm versus 28lm) and 14% higher efficiency (167 lm/W versus 146 lm/W) at identical test current. The maximum current rating increases from 150mA to 180mA, providing additional operational headroom. Physical dimensions remain compatible (5.00 x 3.00mm), with a marginal height reduction (0.80mm versus 0.90mm). ROHS3 Compliant certification exceeds the RoHS Compliant status of the main part. Product Status is Active, ensuring long-term availability and supply chain stability. This part is the recommended substitute for new designs and ongoing production transitions.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MD5WAVMS2 be used as a direct drop-in replacement for SPMWHT541MD5WAVHS2?

A: Yes, SPMWHT541MD5WAVMS2 is a parametric equivalent with identical electrical specifications (2.95V, 65mA, 28lm, 146 lm/W) and mechanical dimensions (5.00 x 3.00mm, 0.90mm height). The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Compatibility depends on your assembly equipment's ability to process the different tape format. Both parts are RoHS Compliant with 2A MSL ratings.

Q: What are the performance differences between SPMWHT541MD5WAVHS2 and SPMWHT541MP5WAVMS4?

A: SPMWHT541MP5WAVMS4 (LM561B Plus) delivers 32lm at 167 lm/W compared to 28lm at 146 lm/W for the main part, representing 14% higher luminous flux and efficiency at the same 65mA test current. Maximum current rating increases from 150mA to 180mA. Physical footprint remains identical (5.00 x 3.00mm), with height reduced from 0.90mm to 0.80mm. Forward voltage remains 2.95V.

Q: Are all three parts compatible with the same PCB layout and assembly process?

A: SPMWHT541MD5WAVHS2 and SPMWHT541MD5WAVMS2 share identical mechanical specifications and can use the same PCB footprint. SPMWHT541MP5WAVMS4 has a 0.10mm lower seated height (0.80mm versus 0.90mm) but maintains the same 5.00 x 3.00mm footprint. Assembly compatibility depends on whether your reflow profile and pick-and-place equipment can accommodate the height variation. The package case differs slightly (Flat Lead Exposed Pad versus Flat Leads), which may affect thermal performance in specific applications.

Q: Why is SPMWHT541MD5WAVHS2 marked "Not For New Designs"?

A: This product status indicates Samsung has transitioned this part to end-of-life. New designs should utilize SPMWHT541MP5WAVMS4 (LM561B Plus, Active status), which offers superior performance, higher maximum current rating, and guaranteed long-term availability. Existing production runs may continue using SPMWHT541MD5WAVHS2 or SPMWHT541MD5WAVMS2 until inventory depletion.

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

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 Compliant (SPMWHT541MP5WAVMS4) represents a more recent certification standard. RoHS Compliant (SPMWHT541MD5WAVHS2 and SPMWHT541MD5WAVMS2) meets the original directive requirements. Both are acceptable for most applications; ROHS3 provides assurance of compliance with the latest regulatory framework.

Q: Can SPMWHT541MP5WAVMS4 be used in applications designed for SPMWHT541MD5WAVHS2?

A: Yes. SPMWHT541MP5WAVMS4 maintains identical forward voltage (2.95V) and nominal test current (65mA), ensuring circuit compatibility. The higher luminous output (32lm versus 28lm) and efficiency (167 lm/W versus 146 lm/W) represent performance improvements. The increased maximum current rating (180mA versus 150mA) provides additional design margin. The 0.10mm height reduction is negligible for most applications. Verify that your specific application does not depend on the exact luminous output of the original part.

Q: What packaging considerations apply when substituting between these parts?

A: SPMWHT541MD5WAVHS2 ships in Tape & Reel (TR) format; SPMWHT541MD5WAVMS2 ships in Cut Tape (CT) & Digi-Reel® format; SPMWHT541MP5WAVMS4 ships in Tape & Reel (TR) format. Verify your assembly equipment compatibility with the tape format before ordering. TR and CT formats require different feeder configurations on pick-and-place machines. All three parts carry identical Moisture Sensitivity Level (2A, 4 Weeks), requiring the same storage and handling protocols.

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

A: All three parts specify identical thermal resistance of 16°C/W. However, SPMWHT541MP5WAVMS4 has a slightly lower seated height (0.80mm versus 0.90mm), which may marginally improve thermal coupling to the PCB in specific thermal management designs. For most applications, thermal performance is equivalent across all three parts.
