Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCP9VT78HPL1VLS06E are identified based on the following critical parameters that determine functional compatibility:

• Color and CCT: Warm white 3000K with 5-Step MacAdam Ellipse specification
• CRI (Color Rendering Index): 90 minimum for color accuracy
• Forward Voltage Range: 2.8V to 2.9V (acceptable tolerance for series operation)
• Mounting Type: Surface Mount (SMD)
• RoHS Compliance: Required for regulatory compliance
• Base Product Number: SCP9VT78 family designation

Parameters that may vary within acceptable limits for substitution include package size (0505 vs. 0606), test current (65mA vs. 150mA), viewing angle (120° vs. 150°), and absolute flux values, provided the substitute maintains the same color temperature, CRI, and forward voltage characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SCP9VT78HEL1VLS06E (LM101B series) is a direct substitute for the obsolete SCP9VT78HPL1VLS06E (LM101A series) based on the following engineering criteria:

Color and Photometric Compatibility: Both parts maintain identical warm white 3000K color temperature with 5-Step MacAdam Ellipse specification and 90 CRI, ensuring color consistency in lighting applications.

Electrical Compatibility: Forward voltage differs by 0.1V (2.9V vs. 2.8V), which is within acceptable tolerance for series-connected LED circuits. The substitute operates at lower test current (65mA vs. 150mA), resulting in higher luminous efficacy (126 lm/W vs. 94 lm/W).

Regulatory Compliance: Both parts are RoHS Compliant with identical MSL ratings (2A, 4 Weeks), meeting environmental and moisture sensitivity requirements.

Product Status: The substitute is Active status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Physical Considerations: The substitute uses a larger 0606 (1616 Metric) package versus the 0505 (1313 Metric) main part. PCB layout and footprint modifications are required. Height difference is minimal (0.42mm vs. 0.45mm).

Frequently Asked Questions (FAQ)

Q: Can the SCP9VT78HEL1VLS06E directly replace the SCP9VT78HPL1VLS06E without circuit modifications?

A: The substitute maintains compatible forward voltage (2.8V vs. 2.9V) and identical color temperature/CRI specifications. However, the package size differs (0606 vs. 0505), requiring PCB footprint redesign. Circuit current limiting resistors may require adjustment due to the 0.1V forward voltage difference.

Q: What is the impact of the different test currents (65mA vs. 150mA)?

A: Test current specifications define the measurement conditions for flux and efficiency ratings. The substitute's lower test current (65mA) reflects its design for lower-power applications. Actual circuit operation depends on the current-limiting design of your application, not the test current specification.

Q: Are there viewing angle differences that affect application suitability?

A: The main part provides 150° viewing angle while the substitute provides 120°. This difference affects light distribution characteristics. Applications requiring wide-angle illumination may need design review.

Q: Is the larger package size (0606 vs. 0505) a significant constraint?

A: Package size increase from 1.18mm to 1.70mm per side requires PCB layout modification. Height increase is negligible (0.42mm to 0.45mm). Space availability on the PCB must be verified before substitution.

Q: Why does the substitute have higher lumens/watt efficiency?

A: The LM101B series (substitute) represents a newer generation with improved efficiency (126 lm/W vs. 94 lm/W). This is a performance advantage, not a compatibility issue.

Q: Are both parts RoHS compliant?

A: Yes, both SCP9VT78HPL1VLS06E and SCP9VT78HEL1VLS06E are RoHS Compliant with identical MSL ratings, meeting regulatory requirements for restricted substance use.
