Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MJ7WAQSS0 is determined by the following critical parameters:

Electrical Compatibility:

• Color temperature: 5700K (cool white)
• Forward voltage: 2.95V
• Test current: 65mA
• Maximum current: 180mA
• CRI: 90
• Viewing angle: 120°

Mechanical Compatibility:

• Surface mount technology
• Package classification: 5630 metric family
• Thermal resistance: 15°C/W

Regulatory Compliance:

• RoHS3 Compliant
• REACH Unaffected

The substitute part SPMWHT541MP7WAQSS0 maintains electrical equivalence across all critical parameters while operating within the same thermal and mechanical constraints. Both parts belong to the Samsung LM561B family with identical color temperature, forward voltage, test current, maximum current, CRI, and viewing angle specifications.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WAQSS0 is the manufacturer-recommended substitute for the SPMWHT541MJ7WAQSS0. Both parts maintain identical electrical specifications across forward voltage, test current, maximum current, color temperature, CRI, and viewing angle. Both are ROHS3 compliant and REACH unaffected.

The substitute part differs in package designation (4-SMD, Flat Leads versus 2212) and physical dimensions (5.00mm x 3.00mm versus 5.30mm x 3.00mm length, with 0.80mm versus 0.90mm seated height). The substitute exhibits slightly lower luminous flux (30lm versus 31lm at 65mA test current) and efficiency (156 lm/W versus 162 lm/W).

The substitute part carries Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the main part. Selection between these parts depends on PCB layout constraints, thermal management requirements, and acceptable luminous flux tolerance ranges for the application.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAQSS0 be used as a direct replacement for SPMWHT541MJ7WAQSS0?

A: Electrical substitution is valid. Both parts operate at identical forward voltage (2.95V), test current (65mA), maximum current (180mA), color temperature (5700K), CRI (90), and viewing angle (120°). Physical dimensions differ slightly; verify PCB footprint compatibility and thermal management requirements before implementation.

Q: What are the key differences between these parts?

A: The main differences are package designation (2212 versus 4-SMD, Flat Leads), physical dimensions (5.30mm x 3.00mm versus 5.00mm x 3.00mm length), seated height (0.90mm versus 0.80mm), luminous flux (31lm versus 30lm at 65mA), and efficiency (162 lm/W versus 156 lm/W). Product status differs (Last Time Buy versus Active).

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both SPMWHT541MJ7WAQSS0 and SPMWHT541MP7WAQSS0 are ROHS3 compliant and REACH unaffected.

Q: What is the significance of the product status difference?

A: SPMWHT541MJ7WAQSS0 is Last Time Buy, indicating production discontinuation with limited inventory. SPMWHT541MP7WAQSS0 is Active, ensuring ongoing availability and supply chain continuity.

Q: Do these parts have identical thermal characteristics?

A: Both parts have thermal resistance of 15°C/W. Physical height differences (0.90mm versus 0.80mm) may affect thermal management in specific PCB layouts; evaluate thermal performance based on application requirements.

Q: What luminous flux tolerance should be expected?

A: SPMWHT541MJ7WAQSS0 specifies 31lm (29lm ~ 33lm) at 25°C and 65mA. SPMWHT541MP7WAQSS0 specifies 30lm (27lm ~ 33lm) at the same conditions. Both fall within overlapping tolerance ranges; confirm application luminous requirements before selection.
