Substitute Part Grouping Explanation

The SPMWHT541MP7WATMS0 qualifies as a manufacturer-recommended substitute based on the following alignment criteria:

Matching Parameters:

• Series: LM561B Plus (identical product line)
• Color: White, Neutral (identical color specification)
• CCT: 4000K (identical correlated color temperature)
• Voltage - Forward (Vf): 2.95V (identical forward voltage)
• Current - Test: 65mA (identical test current)
• CRI: 90 (identical color rendering index)
• Current - Max: 180mA (identical maximum current rating)
• Viewing Angle: 120° (identical viewing angle)
• Mounting Type: Surface Mount (identical mounting method)
• RoHS Status: ROHS3 Compliant (identical compliance)
• Thermal Resistance: 15°C/W (identical thermal characteristic)

Allowable Variations:

• Package form factor: 2212 to 4-SMD, Flat Leads (both 5630 metric equivalent packages)
• Physical dimensions: Minor variations within metric equivalence
• Flux output: 31lm (main part) vs. 27lm (substitute) - within acceptable tolerance range for same series
• Lumens/Watt efficiency: 162 lm/W vs. 141 lm/W - performance characteristic variation
• Product Status: Last Time Buy (main) vs. Active (substitute) - ensures ongoing availability

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WATMS0 is the manufacturer-recommended substitute for the SPMWHT541MJ7WATMS0. Both components maintain identical electrical specifications for forward voltage, test current, maximum current, and color characteristics. The substitute part is currently in Active production status, ensuring supply continuity for applications transitioning from the Last Time Buy SPMWHT541MJ7WATMS0.

Both parts meet ROHS3 compliance and carry identical thermal resistance ratings. The substitute offers equivalent performance within the LM561B Plus product line. Physical package dimensions show minor variations (5.30mm vs. 5.00mm length; 0.90mm vs. 0.80mm height), which remain compatible with standard 5630 metric footprints used in surface mount assembly processes.

The flux output difference (31lm vs. 27lm) represents a performance characteristic variation within the same product series. The substitute's lower lumens-per-watt efficiency (141 lm/W vs. 162 lm/W) should be evaluated against specific application brightness requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WATMS0 directly replace SPMWHT541MJ7WATMS0 in existing designs?

A: Yes. Both parts share identical electrical specifications including forward voltage (2.95V), test current (65mA), maximum current (180mA), color temperature (4000K), and CRI (90). The substitute maintains the same 120° viewing angle and surface mount compatibility. Minor physical dimension variations remain within standard 5630 metric package tolerances.

Q: What is the difference between the 2212 and 4-SMD, Flat Leads package designations?

A: Both designations refer to equivalent 5630 metric form factors used in surface mount LED applications. The 2212 designation and 4-SMD, Flat Leads represent different packaging nomenclature for the same metric footprint. Standard PCB assembly equipment accommodates both package styles without modification.

Q: Why does the substitute part have lower flux output (27lm vs. 31lm)?

A: The flux output difference reflects manufacturing variation within the LM561B Plus series tolerance range. The substitute's 27lm output (24lm ~ 30lm tolerance) overlaps with the main part's specification band. Applications requiring specific minimum brightness should confirm the substitute meets their flux requirements.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance status and share the same ECCN (EAR99) and HTSUS classifications. Thermal resistance ratings are identical at 15°C/W.

Q: What inventory status should I consider for procurement?

A: The main part (SPMWHT541MJ7WATMS0) carries Last Time Buy status with 1034 units in stock. The substitute (SPMWHT541MP7WATMS0) is in Active production with 43274 units available. For new designs and long-term production, the Active substitute part ensures supply continuity.
