• Color temperature (6500K)
• Luminous flux at test conditions (60lm nominal, 58lm ~ 62lm range)
• Forward voltage (3.1V typical)
• Test current (150mA)
• Maximum current rating (160mA)
• Luminous efficacy (129 lm/W)
• Color Rendering Index (80)

Mechanical Equivalence Criteria:

• Package format (1113 / 2835 Metric)
• Physical dimensions (3.50mm x 2.80mm)
• Maximum seated height (0.75mm)
• Viewing angle (120°)
• Mounting type (Surface Mount)
• Thermal resistance (25°C/W)

Compliance Criteria:

• RoHS compliance status

The substitute part SPMWH1228FD5WAP0SA maintains identical electrical and mechanical specifications with the main part, differing only in RoHS compliance designation and packaging inventory levels.

Parameter Comparison

Engineering Selection Recommendations

Both SPMWH1228FD5WAPKSA and SPMWH1228FD5WAP0SA are Active status products from Samsung Semiconductor with full compliance certifications. Selection between these parts is based on the following factors:

RoHS Compliance Designation: The SPMWH1228FD5WAPKSA carries RoHS Compliant status, while SPMWH1228FD5WAP0SA carries ROHS3 Compliant status. Both designations indicate compliance with Restriction of Hazardous Substances directives. Applications requiring specific RoHS revision compliance should reference the applicable regulatory requirements for the target market.

Inventory and Availability: SPMWH1228FD5WAP0SA maintains significantly higher inventory levels (81,037 pieces) compared to SPMWH1228FD5WAPKSA (851 pieces). For high-volume production requirements or extended supply chain planning, the substitute part offers greater availability.

Packaging Format: Both parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The 2835 metric package format is standard for surface mount LED applications with 3.50mm x 2.80mm footprint dimensions.

Electrical and Thermal Performance: Identical specifications across all electrical parameters (voltage, current, luminous flux, efficacy) and thermal characteristics (25°C/W thermal resistance) ensure direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1228FD5WAP0SA be used as a direct replacement for SPMWH1228FD5WAPKSA?

A: Yes. Both parts are electrically and mechanically equivalent with identical specifications across all critical parameters including forward voltage (3.1V), test current (150mA), luminous flux (60lm), color temperature (6500K), package dimensions (3.50mm x 2.80mm), and thermal resistance (25°C/W). Both are Active status products with RoHS compliance certifications.

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

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. The specific revision designation (RoHS3) reflects the applicable regulatory framework version. Applications should verify compliance requirements against target market regulations.

Q: Are these parts compatible with existing PCB designs for 2835 package LEDs?

A: Yes. Both parts use the 1113 (2835 Metric) package format with identical dimensions (3.50mm x 2.80mm) and maximum seated height (0.75mm). They are compatible with PCB designs and assembly processes specified for 2835 metric package surface mount LEDs.

Q: What is the viewing angle specification and how does it affect application design?

A: Both parts have a 120° viewing angle, which defines the cone of light distribution from the LED. This specification is identical between the main part and substitute, ensuring consistent light distribution characteristics in lighting applications.

Q: What are the current operating parameters for these LEDs?

A: Test current is 150mA with a maximum current rating of 160mA. Forward voltage at typical conditions is 3.1V. These parameters are identical for both SPMWH1228FD5WAPKSA and SPMWH1228FD5WAP0SA.

Q: How does the Color Rendering Index (CRI) of 80 affect color accuracy?

A: A CRI of 80 indicates good color rendering capability for general lighting applications. This specification is identical between both parts, ensuring consistent color reproduction characteristics.

Q: What is the thermal resistance specification and why is it important?

A: Thermal resistance of 25°C/W indicates the temperature rise per watt of power dissipated. This specification is identical for both parts and is critical for thermal management in high-density LED array applications.

Q: Are these parts suitable for automated assembly processes?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging format, which is standard for automated pick-and-place assembly equipment used in surface mount technology (SMT) manufacturing.

Q: What is the Moisture Sensitivity Level (MSL) and storage requirement?

A: Both parts have MSL 2A rating with a 4-week moisture sensitivity window. Components must be stored in controlled humidity environments and used within the specified timeframe after packaging opening to prevent moisture absorption.
