Engineering Selection Recommendations

The PI49FCT20802LEX is the direct substitute for the PI49FCT20802LE. Both components are manufactured by Diodes Incorporated and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product lifecycle status: the PI49FCT20802LE is classified as Obsolete, while the PI49FCT20802LEX maintains Active status. The PI49FCT20802LEX is supplied in Tape & Reel (TR) packaging format, which is standard for production volume applications.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing processes and long-term storage requirements. Selection between these parts should be based on current inventory availability and packaging requirements for your production workflow.

Frequently Asked Questions (FAQ)

Q: Can the PI49FCT20802LEX directly replace the PI49FCT20802LE in existing designs?

A: Yes. The PI49FCT20802LEX is electrically and mechanically equivalent to the PI49FCT20802LE. All functional parameters, including fanout ratio, frequency specification, logic levels, supply voltage, temperature range, and package dimensions are identical. Direct substitution is supported without design modification.

Q: What is the significance of the Obsolete status for the PI49FCT20802LE?

A: Obsolete status indicates that the PI49FCT20802LE is no longer in active production. The PI49FCT20802LEX, with Active status, represents the current production equivalent and is the recommended selection for new designs and ongoing production support.

Q: Are there packaging differences between these parts?

A: The PI49FCT20802LE is supplied in standard packaging, while the PI49FCT20802LEX is supplied in Tape & Reel (TR) format. Both use the identical 16-TSSOP surface mount package. Tape & Reel packaging is standard for automated assembly processes and high-volume production.

Q: Do both parts meet the same regulatory and compliance requirements?

A: Yes. Both the PI49FCT20802LE and PI49FCT20802LEX are ROHS3 compliant and carry MSL Level 1 rating. They meet identical regulatory requirements for environmental compliance and moisture sensitivity classification.

Q: What are the key parameters that define substitution compatibility for this clock buffer?

A: Substitution compatibility is determined by: 1:5 fanout ratio, 150 MHz maximum frequency, CMOS/TTL logic compatibility, 2.3V to 2.7V supply voltage range, 16-TSSOP package specification, -40°C to +85°C operating temperature range, and ROHS3/MSL Level 1 compliance.
