SCMP13WBC8W1 Equivalent & Substitute Parts

Part Overview

The SCMP13WBC8W1 is a white diffused LED chip manufactured by Rohm Semiconductor, part of the PicoLED™ series. This component is a 2-SMD, No Lead surface mount LED designed for white light indication applications with a forward voltage of 2.9V and a brightness rating of 150mcd at 5mA test current. The product is currently obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCMP13WBC8W1 is determined by the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf) must remain 2.9V to ensure circuit compatibility without redesign
• Test current of 5mA establishes the brightness reference point
• Millicandela rating must be within acceptable operational range for the intended indication function

Mechanical & Packaging Compatibility:

• Surface mount mounting type is required
• Physical dimensions (1.00mm L x 0.60mm W) must be maintained for PCB layout compatibility
• Height constraint (maximum 0.25mm to 0.30mm) is critical for assembly clearance

Regulatory & Environmental:

• RoHS3 compliance is mandatory for current production standards
• MSL rating of 3 ensures equivalent moisture handling during storage and assembly

The SMLP14WBCN1W1 qualifies as a substitute based on matching electrical parameters (2.9V forward voltage, 5mA test current), surface mount configuration, equivalent physical footprint, and identical regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The SMLP14WBCN1W1 is the qualified substitute for the obsolete SCMP13WBC8W1 based on the following engineering criteria:

Electrical Equivalence: Both components operate at 2.9V forward voltage with 5mA test current, ensuring direct circuit compatibility without modification to bias networks or current-limiting resistor values.

Physical Compatibility: Identical footprint dimensions (1.00mm L x 0.60mm W) allow direct PCB layout substitution. The height difference of 0.05mm (0.30mm vs. 0.25mm maximum) remains within typical assembly clearance tolerances for surface mount processes.

Regulatory Compliance: Both components maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental handling and long-term reliability in production environments.

Product Availability: The SMLP14WBCN1W1 is currently in active production status with confirmed inventory availability, providing supply chain continuity for ongoing applications.

Brightness Consideration: The substitute part provides 180mcd versus the original 150mcd at identical test conditions, representing a 20% increase in luminous intensity. This enhanced brightness is functionally acceptable for indication applications and does not introduce circuit stress.

Frequently Asked Questions (FAQ)

Q: Can the SMLP14WBCN1W1 be used as a direct replacement without PCB modification?

A: Yes. The SMLP14WBCN1W1 maintains identical electrical parameters (2.9V forward voltage, 5mA test current) and footprint dimensions (1.00mm L x 0.60mm W), enabling direct substitution on existing PCB layouts without circuit redesign or component repositioning.

Q: What is the significance of the package designation change from "2-SMD, No Lead" to "0402 (1006 Metric)"?

A: Both designations describe the same physical package format. The 0402 (1006 Metric) notation is the industry-standard IPC designation for a 1.00mm x 0.60mm surface mount component. The package change reflects standardized nomenclature rather than a physical difference.

Q: Does the 0.05mm height difference affect assembly compatibility?

A: No. The height increase from 0.25mm to 0.30mm maximum remains within standard surface mount assembly tolerances and does not impact reflow soldering, component placement accuracy, or clearance to adjacent components in typical PCB designs.

Q: Why is the substitute part brighter (180mcd vs. 150mcd)?

A: The SMLP14WBCN1W1 delivers higher luminous intensity at the same test current and forward voltage. This brightness increase is a result of improved LED die efficiency in the newer product generation and does not create circuit compatibility issues for indication applications.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both components are ROHS3 compliant with identical MSL ratings of 3 (168 Hours), ensuring equivalent regulatory status and environmental handling requirements throughout the supply chain and manufacturing process.

Q: What inventory status should be considered when selecting between these parts?

A: The SCMP13WBC8W1 is obsolete with no ongoing production. The SMLP14WBCN1W1 is in active production with confirmed inventory availability, making it the only viable option for new designs and ongoing production support.
