Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the SPMWHT325AD5YBU0S0 is based on the following critical parameters that define functional equivalence:

Primary Matching Criteria:

• Color specification: White, Warm
• CCT (Correlated Color Temperature): 3500K
• CRI (Color Rendering Index): 80 minimum
• Mounting type: Surface Mount
• Luminous flux range: Compatible with 67 lm nominal output
• Viewing angle: 120° or greater

Secondary Compatibility Factors:

• Forward voltage tolerance and circuit design accommodation
• Maximum current rating sufficient for application requirements
• Package dimensions and height constraints for PCB layout
• Thermal resistance characteristics for thermal management
• RoHS and environmental compliance status

The substitute part MP-3030-1100-35-80 (Luminus Devices Inc., MP-3030 series) meets the primary color and temperature specifications. However, electrical parameters differ significantly: the MP-3030 operates at 3V forward voltage versus 5.96V for the SPMWHT325AD5YBU0S0, and uses a different package form factor (1212/3030 Metric versus 2-SMD, No Lead). These differences require circuit redesign and PCB layout modification for successful substitution.

Parameter Comparison

Engineering Selection Recommendations

For SPMWHT325AD5YBU0S0 Substitution:

The SPMWHT325AD5YBU0S0 is classified as Obsolete. The identified substitute MP-3030-1100-35-80 is classified as Not For New Designs, indicating both parts have limited availability for future production.

Electrical Compatibility Considerations:

The forward voltage differential (5.96V versus 3.0V) represents a fundamental circuit design difference. Applications designed for the SPMWHT325AD5YBU0S0 require series resistor or current-limiting circuit modifications to accommodate the MP-3030-1100-35-80. Direct pin-for-pin substitution is not feasible without circuit redesign.

Mechanical Compatibility Considerations:

Package form factors differ significantly. The SPMWHT325AD5YBU0S0 uses a 2-SMD, No Lead package (3623 supplier designation) with dimensions 3.60 × 2.30 mm and 0.70 mm maximum height. The MP-3030-1100-35-80 uses a 1212 (3030 Metric) package with dimensions 3.00 × 3.00 mm and 0.52 mm maximum height. PCB footprint redesign is required.

Compliance Status:

Both parts maintain RoHS compliance. The SPMWHT325AD5YBU0S0 is RoHS Compliant; the MP-3030-1100-35-80 is ROHS3 Compliant. The MP-3030-1100-35-80 carries REACH Unaffected status.

Luminous Performance:

Both parts deliver comparable luminous flux at their respective test currents (67 lm and 64 lm). The MP-3030-1100-35-80 demonstrates superior efficiency at 142 lm/W versus 112 lm/W for the SPMWHT325AD5YBU0S0.

Thermal Management:

The MP-3030-1100-35-80 exhibits lower thermal resistance (11°C/W versus 15°C/W), providing improved thermal performance in applications with thermal constraints.

Frequently Asked Questions (FAQ)

Q: Can the MP-3030-1100-35-80 be used as a direct replacement for the SPMWHT325AD5YBU0S0?

A: No. While both parts share identical color temperature (3500K) and CRI (80) specifications, the forward voltage differs significantly (3.0V versus 5.96V). Direct substitution requires circuit redesign to accommodate the voltage differential. Additionally, package form factors differ, necessitating PCB footprint modification.

Q: What are the key parameters that must match for LED substitution?

A: Critical matching parameters include color specification (White, Warm), CCT (3500K), CRI (80), mounting type (Surface Mount), and luminous flux range. Secondary parameters include forward voltage, maximum current rating, package dimensions, and thermal characteristics. All parameters must be evaluated within the context of the specific application circuit design.

Q: Are both parts suitable for new product designs?

A: No. The SPMWHT325AD5YBU0S0 is classified as Obsolete. The MP-3030-1100-35-80 is classified as Not For New Designs. Both parts have limited availability. New product designs should identify alternative parts with Active product status from current manufacturer catalogs.

Q: What is the impact of the different package sizes?

A: The SPMWHT325AD5YBU0S0 (3.60 × 2.30 mm, 0.70 mm height) and MP-3030-1100-35-80 (3.00 × 3.00 mm, 0.52 mm height) have different footprints and heights. Applications with space constraints or specific PCB layout requirements may be incompatible with the substitute. PCB redesign is necessary.

Q: How do the thermal characteristics compare?

A: The MP-3030-1100-35-80 has lower thermal resistance (11°C/W) compared to the SPMWHT325AD5YBU0S0 (15°C/W). This indicates superior thermal performance. For applications operating at elevated ambient temperatures or with thermal constraints, the MP-3030-1100-35-80 provides better thermal management.

Q: What is the moisture sensitivity difference?

A: The SPMWHT325AD5YBU0S0 has MSL 2A (4 Weeks storage limit). The MP-3030-1100-35-80 has MSL 3 (168 Hours storage limit). The SPMWHT325AD5YBU0S0 requires more stringent moisture control during storage and handling.

Q: Are both parts RoHS compliant?

A: Yes. The SPMWHT325AD5YBU0S0 is RoHS Compliant. The MP-3030-1100-35-80 is ROHS3 Compliant. Both meet RoHS requirements. The MP-3030-1100-35-80 additionally carries REACH Unaffected status.
