Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541ML5XARUS6 is determined by strict equivalence across the following parameters:

Series designation (LM561C)
Color and correlated color temperature (White, Cool, 5000K)
Electrical performance: forward voltage (2.75V typ), test current (65mA), maximum current (200mA)
Luminous flux at test conditions (38lm ±1lm @ 25°C, 65mA)
Luminous efficacy (212–213 lm/W)
Color rendering index (CRI 80)
Optical characteristics (120° viewing angle)
Mechanical compatibility: 4-SMD flat leads, 5630 package, 5.00 × 3.00 × 0.80mm envelope
Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

The substitute part SPMWHT541ML5XAR0S6 meets all these criteria and is therefore classified as a parametric equivalent.

Engineering Selection Recommendations

Both SPMWHT541ML5XARUS6 and SPMWHT541ML5XAR0S6 are active production components from Samsung Semiconductor with identical electrical, optical, and mechanical specifications. Selection between these parts is based on availability and supply chain requirements:

SPMWHT541ML5XARUS6: 697 pcs in stock
SPMWHT541ML5XAR0S6: 1054 pcs in stock, MSL 2A (4 weeks)

Both parts carry ROHS3 compliance and EAR99 export classification. The substitute part includes moisture sensitivity level (MSL) specification of 2A with a 4-week floor life, which must be observed during storage and handling. No electrical or mechanical redesign is required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAR0S6 be used as a direct replacement for SPMWHT541ML5XARUS6?

A: Yes. Both parts are parametric equivalents with identical electrical performance (2.75V, 65mA, 38lm @ 25°C), optical characteristics (5000K, 120° viewing angle, CRI 80), and mechanical compatibility (4-SMD 5630 package, 5.00 × 3.00 × 0.80mm). No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The part numbers differ in their suffix designations (ARUS6 vs. AR0S6), which reflect internal Samsung manufacturing or inventory tracking codes. The electrical and mechanical specifications are identical. SPMWHT541ML5XAR0S6 includes explicit moisture sensitivity level (MSL 2A, 4 weeks) documentation.

Q: Are there any storage or handling differences?

A: SPMWHT541ML5XAR0S6 specifies MSL 2A with a 4-week floor life. Components must be stored in controlled humidity environments and used within the specified timeframe after opening. SPMWHT541ML5XARUS6 does not include explicit MSL documentation in the provided data.

Q: Can these parts be mixed in the same production batch?

A: Yes. Both parts meet identical electrical, optical, and mechanical specifications and carry the same regulatory compliance (ROHS3, REACH Unaffected, EAR99). They are mechanically and electrically interchangeable in all applications.

Q: What is the thermal resistance specification?

A: Both parts have a thermal resistance of 12°C/W, indicating identical thermal performance in the 5630 package configuration.

Q: Are these parts suitable for high-brightness applications?

A: These are standard brightness LEDs in the LM561C series with 38lm output at 65mA test current and 213 lm/W efficacy. Application suitability depends on specific luminous flux and power consumption requirements of the end application.
