Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PLED6USW is determined by strict alignment of the following critical parameters:

• Voltage rating: 6V
• Clamping voltage: 16V
• Technology classification: LED Shunt
• Circuit count: 1
• Package type: DO-214AA (SMB)
• Mounting configuration: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The PLED6US qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications. The primary distinction is product status: PLED6US is active, whereas PLED6USW is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The PLED6US is the direct equivalent for PLED6USW applications. Both components share identical electrical specifications, mechanical dimensions, and compliance certifications. The PLED6US maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory alignment.

Selection of PLED6US over PLED6USW is driven by product lifecycle considerations: PLED6USW obsolescence status creates supply chain risk, while PLED6US provides continuity for LED protection circuits requiring 6V shunt technology in DO-214AA surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can PLED6US directly replace PLED6USW in existing designs?

A: Yes. Both components are electrically and mechanically identical across all specified parameters, including voltage rating, clamping voltage, package type, and mounting configuration. No circuit redesign is required.

Q: What is the primary difference between PLED6USW and PLED6US?

A: Product status and packaging format. PLED6USW is obsolete and supplied in bulk packaging, while PLED6US is active and available in Tape & Reel format. Electrical and mechanical specifications are identical.

Q: Are there compliance differences between these parts?

A: No. Both components are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited) and ECCN/HTSUS classifications.

Q: What packaging options are available for the substitute part?

A: PLED6US is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. This differs from PLED6USW bulk packaging but does not affect electrical performance.

Q: Is the DO-214AA package identical between both parts?

A: Yes. Both PLED6USW and PLED6US use the DO-214AA (SMB) package with identical mechanical dimensions and pin configuration, ensuring PCB footprint compatibility.
