Substitute Part Grouping Explanation

Substitution logic for the SPMWHT541ML7XATNS0 is based on the following allowed parameters:

Parametric Equivalents (Full Compatibility): Parts SPMWHT541ML7XAT0S0, SPMWHT541ML7XATMS0, and SPMWHT541ML7XATSS0 are parametric equivalents. These parts maintain identical electrical and mechanical specifications: LM561C series, 4000K neutral white, 2.75V forward voltage, 29 lm flux output at 65mA, 162 lm/W efficiency, 90 CRI, 120° viewing angle, 12°C/W thermal resistance, and 5630 package dimensions. The only differences are in packaging tape configuration (indicated by suffix variations: 0S0, MS0, SS0) and product status (Active vs. Not For New Designs). These parts are direct substitutes for identical circuit performance.

Similar Substitute (Functional Alternative): Part SPMWHT541MP7WATMS0 is a functional substitute from the LM561B Plus series. While maintaining the same color (neutral white 4000K), package (5630, 4-SMD flat leads), mounting type (surface mount), and viewing angle (120°), this part introduces the following parameter differences: forward voltage increases to 2.95V, flux output decreases to 27 lm at 65mA, efficiency reduces to 141 lm/W, maximum current is 180mA (vs. 200mA), and thermal resistance increases to 15°C/W. The LM561B Plus series represents a newer product generation with Active status. This substitute is suitable for applications where the forward voltage increase and reduced efficiency are acceptable within circuit design margins.

Engineering Selection Recommendations

For Direct Replacement (Identical Performance): Select SPMWHT541ML7XAT0S0, SPMWHT541ML7XATMS0, or SPMWHT541ML7XATSS0. These parts are parametric equivalents with Active product status, ensuring long-term supply availability. All three maintain the LM561C series specifications, identical electrical performance (2.75V, 29 lm, 162 lm/W), and mechanical compatibility. Selection among these three should be based on packaging tape configuration requirements and inventory availability. All three carry RoHS Compliant certification and 2A MSL rating.

For Functional Substitution (LM561B Plus Alternative): Select SPMWHT541MP7WATMS0 when the LM561C series becomes unavailable and circuit design can accommodate parameter variations. This part operates at 2.95V forward voltage (0.20V higher), delivers 27 lm flux (2 lm lower), and provides 141 lm/W efficiency (21 lm/W lower). Maximum current rating is 180mA (20mA lower) and thermal resistance is 15°C/W (3°C/W higher). The LM561B Plus series carries Active product status with significantly higher inventory (43,274 pcs), providing superior long-term supply security. This part meets ROHS3 Compliant certification. Use this substitute only when circuit design margins accommodate the increased forward voltage and reduced efficiency.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML7XAT0S0, SPMWHT541ML7XATMS0, and SPMWHT541ML7XATSS0 be used interchangeably with SPMWHT541ML7XATNS0?

A: Yes. These three parts are parametric equivalents with identical electrical and mechanical specifications. The suffix variations (0S0, MS0, SS0) indicate different packaging tape configurations. All three maintain 2.75V forward voltage, 29 lm flux output, 162 lm/W efficiency, and 5630 package dimensions. Selection should be based on specific tape reel requirements and availability.

Q: What are the key differences between the LM561C and LM561B Plus series?

A: The LM561B Plus (SPMWHT541MP7WATMS0) represents a newer product generation with the following parameter differences: forward voltage increases from 2.75V to 2.95V, flux output decreases from 29 lm to 27 lm at 65mA test current, efficiency reduces from 162 lm/W to 141 lm/W, maximum current rating decreases from 200mA to 180mA, and thermal resistance increases from 12°C/W to 15°C/W. Both series maintain identical color (4000K neutral white), CRI (90), viewing angle (120°), and 5630 package format.

Q: Is the SPMWHT541MP7WATMS0 a direct replacement for SPMWHT541ML7XATNS0?

A: No. While both parts share the same color temperature (4000K), package format (5630), and viewing angle (120°), the LM561B Plus introduces measurable parameter differences. The increased forward voltage (2.95V vs. 2.75V) and reduced efficiency (141 lm/W vs. 162 lm/W) require circuit design verification. Use this part only when LM561C series availability is exhausted and circuit design margins accommodate these variations.

Q: Why is SPMWHT541ML7XATNS0 marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and Samsung Semiconductor is not recommending it for new product development. Existing inventory remains available for legacy product support and maintenance. For new designs, select from the Active status alternatives: SPMWHT541ML7XAT0S0, SPMWHT541ML7XATMS0, SPMWHT541ML7XATSS0, or SPMWHT541MP7WATMS0.

Q: Are all substitute parts RoHS compliant?

A: Yes. SPMWHT541ML7XAT0S0, SPMWHT541ML7XATMS0, and SPMWHT541ML7XATSS0 carry RoHS Compliant certification. SPMWHT541MP7WATMS0 carries ROHS3 Compliant certification. All parts meet environmental compliance requirements.

Q: What is the moisture sensitivity level for these parts?

A: All parts listed carry MSL 2A rating with a 4-week floor life. This indicates moderate moisture sensitivity requiring standard dry storage and handling procedures.

Q: Which substitute part offers the best long-term supply availability?

A: SPMWHT541MP7WATMS0 (LM561B Plus) offers the highest inventory level at 43,274 pcs with Active product status, providing superior long-term supply security compared to the LM561C alternatives.
