Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCP7PTF1HPLAPTM34E is determined by the following critical parameters:

Primary Substitution Criteria:

• Color specification: White, Cool
• Correlated Color Temperature (CCT): 6500K
• Forward voltage (Vf): 2.9V nominal
• Test current: 350mA
• Mounting type: Surface Mount
• CRI: 70

Secondary Compatibility Factors:

• Viewing angle tolerance (140° preferred, 120° acceptable with application review)
• Package form factor and thermal characteristics
• Maximum current rating (1.4A–1.5A range)
• Lumens/Watt efficiency (150–165 lm/W range)
• RoHS and MSL compliance

Two substitute parts are identified based on these parameters:

1. SCP7PTF1HEL1PKN34E (LH181B series): Direct functional equivalent with improved efficiency and active product status
2. SCP7QTF1HPLAQTM34E (LH181A series, 5700K): Parametric equivalent with alternative CCT specification

Parameter Comparison

Engineering Selection Recommendations

SCP7PTF1HEL1PKN34E (LH181B Series)

This substitute is the preferred choice for new designs and ongoing procurement. The LH181B series maintains identical electrical specifications (2.9V, 350mA, 6500K CCT, CRI 70) while offering measurable improvements: 10 lm/W higher efficiency (163 vs. 153 lm/W), superior thermal performance (2°C/W vs. 3°C/W), and active product status ensuring long-term availability. The package footprint is slightly larger (2.36mm vs. 1.91mm), requiring PCB layout verification. ROHS3 compliance exceeds the RoHS Compliant status of the main part. This substitute is suitable for direct replacement in applications where the 120° viewing angle (versus 140°) is acceptable.

SCP7QTF1HPLAQTM34E (LH181A Series, 5700K)

This part provides parametric equivalence with identical package geometry (0707/1919 Metric), thermal characteristics (3°C/W), and viewing angle (140°). The primary distinction is CCT specification at 5700K rather than 6500K. Selection of this substitute is appropriate only when 5700K color temperature is functionally acceptable or when PCB layout constraints prohibit the larger 2-SMD package of the LH181B. Product status remains obsolete, limiting long-term procurement viability.

Compliance Considerations

All three parts maintain MSL 2A (4 Weeks) moisture sensitivity classification and surface mount mounting type. RoHS and ROHS3 compliance certifications are current across all options.

Frequently Asked Questions (FAQ)

Q: Can SCP7PTF1HEL1PKN34E be used as a direct drop-in replacement for SCP7PTF1HPLAPTM34E?

A: Electrical and thermal performance are directly compatible. The package footprint differs (2.36mm vs. 1.91mm), requiring PCB layout modification. The viewing angle is reduced from 140° to 120°. Functional compatibility depends on application-specific optical and spatial requirements.

Q: What is the significance of the CCT difference between 6500K and 5700K?

A: CCT (Correlated Color Temperature) defines perceived color tone. 6500K represents daylight-neutral white; 5700K is slightly warmer. These are distinct specifications. SCP7QTF1HPLAQTM34E should be selected only when 5700K is an acceptable alternative to the original 6500K requirement.

Q: Why is SCP7PTF1HEL1PKN34E listed as "Active" while the main part is "Obsolete"?

A: Product status reflects manufacturer lifecycle classification. Active status indicates current production and long-term availability. Obsolete status indicates discontinued production. For procurement planning, active parts are preferred to ensure supply continuity.

Q: Are there thermal management differences between these parts?

A: Yes. SCP7PTF1HEL1PKN34E has superior thermal resistance (2°C/W vs. 3°C/W), dissipating heat more efficiently. This is advantageous in thermally constrained applications. The larger package footprint contributes to this improvement.

Q: What does "2-SMD, No Lead" package mean compared to "0707 (1919 Metric)"?

A: Both are surface mount packages. 0707 (1919 Metric) is a compact square format (1.91mm × 1.91mm). 2-SMD, No Lead is a slightly larger format (2.36mm × 2.36mm) with two solder pads. The 2-SMD format provides improved thermal and electrical contact characteristics.

Q: Are all three parts RoHS compliant?

A: Yes. SCP7PTF1HPLAPTM34E and SCP7QTF1HPLAQTM34E are RoHS Compliant. SCP7PTF1HEL1PKN34E is ROHS3 Compliant, representing a more current compliance standard. All meet environmental regulatory requirements.

Q: What is MSL 2A (4 Weeks)?

A: Moisture Sensitivity Level (MSL) 2A indicates the component can be exposed to ambient conditions (30°C, 60% relative humidity) for up to 4 weeks before soldering without degradation. All three parts share this specification, requiring identical handling and storage protocols.
