Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT223MD5WATMS0 is determined by the following critical parameters:

Primary Matching Criteria:

• Color specification: White, Neutral
• CCT: 4000K
• Viewing angle: 120°
• Mounting type: Surface Mount
• CRI: 80
• RoHS compliance status

Secondary Compatibility Factors:

• Luminous flux range at 25°C (21–31 lm acceptable tolerance)
• Lumens/Watt efficiency (130–150 lm/W range)
• Forward voltage tolerance (2.5–3.5V acceptable for circuit redesign)
• Package form factor (0909/2323 or 1411/3528 metric packages compatible with standard pick-and-place equipment)

The EAPL2835WA5 from Everlight Electronics Co Ltd meets these substitution criteria. Both components share identical color temperature, CRI rating, viewing angle, and mounting methodology. Luminous flux output (27 lm) and efficiency (138 lm/W) fall within acceptable operational ranges. Package differences (2323 vs. 3528 metric) require PCB layout modification but do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SPMWHT223MD5WATMS0 is classified as obsolete. The EAPL2835WA5 is active and in production, ensuring long-term supply availability and continued manufacturer support.

Compliance & Certification: Both components meet RoHS requirements. The EAPL2835WA5 carries ROHS3 certification, representing current regulatory compliance standards. The SPMWHT223MD5WATMS0 meets RoHS Compliant status. Both components are classified under ECCN EAR99 and HTSUS 8541.41.0000.

Inventory & Availability: The SPMWHT223MD5WATMS0 has 885 pieces in stock (new original). The EAPL2835WA5 has 23,470 pieces in stock, providing significantly greater supply security for ongoing production.

Implementation Requirements: Substitution of the EAPL2835WA5 requires:

1. PCB layout modification to accommodate the larger 3528 metric package (3.50mm × 2.80mm vs. 2.30mm × 2.30mm)
2. Circuit current-limiting adjustment due to 0.39V higher forward voltage (3.25V vs. 2.86V)
3. Verification of thermal management, as the EAPL2835WA5 has higher thermal resistance (50°C/W vs. 20°C/W)

Frequently Asked Questions (FAQ)

Q: Can the EAPL2835WA5 be used as a direct drop-in replacement for the SPMWHT223MD5WATMS0?

A: No. While both components share identical color temperature (4000K), CRI (80), and viewing angle (120°), the EAPL2835WA5 requires PCB layout modification due to different package dimensions (3528 vs. 2323 metric). Additionally, the higher forward voltage (3.25V vs. 2.86V) necessitates circuit current-limiting adjustment.

Q: What is the impact of the forward voltage difference on circuit design?

A: The EAPL2835WA5 operates at 3.25V compared to 2.86V for the SPMWHT223MD5WATMS0. This 0.39V difference affects the voltage drop across current-limiting resistors. Existing resistor values must be recalculated to maintain the desired operating current (approximately 60–65 mA). Failure to adjust will result in reduced luminous output or component damage.

Q: Are the luminous flux outputs equivalent?

A: Yes. The SPMWHT223MD5WATMS0 delivers 26 lm at 25°C (tolerance 21–31 lm), while the EAPL2835WA5 delivers 27 lm (tolerance 21–33 lm). Both fall within acceptable operational ranges and deliver equivalent luminous efficacy (140 lm/W vs. 138 lm/W).

Q: What are the thermal management implications?

A: The EAPL2835WA5 has thermal resistance of 50°C/W compared to 20°C/W for the SPMWHT223MD5WATMS0. This indicates higher thermal impedance. Applications with strict thermal constraints or high ambient temperatures require thermal analysis to confirm the substitute component remains within safe operating limits.

Q: Does the package size difference affect assembly compatibility?

A: Yes. The EAPL2835WA5 (3528 metric, 3.50mm × 2.80mm) is larger than the SPMWHT223MD5WATMS0 (2323 metric, 2.30mm × 2.30mm). Standard pick-and-place equipment can accommodate both packages, but PCB footprint redesign is mandatory. Verify that the larger package does not create clearance conflicts with adjacent components or mechanical constraints.

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

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard with updated substance restrictions. Both components are acceptable for applications requiring RoHS compliance. ROHS3 certification on the EAPL2835WA5 ensures alignment with current and future regulatory requirements.

Q: Is the moisture sensitivity level a concern for substitution?

A: The SPMWHT223MD5WATMS0 has MSL 2A (4 weeks), while the EAPL2835WA5 has MSL 3 (168 hours). MSL 3 indicates lower moisture sensitivity and longer shelf life under controlled conditions. This is advantageous for supply chain management and reduces risk of moisture-induced failures during storage and handling.
