Substitute Part Grouping Explanation

Substitution of the PCF8564AU/5BD/1,01 is based on the following critical parameters:

Manufacturer Consistency: Both the main part and substitute are manufactured by NXP USA Inc., ensuring design continuity and supply chain reliability.

Functional Category: Both parts belong to the Clock/Timing category and serve as Real Time Clock (RTC) ICs, maintaining functional equivalence.

Base Product Number Alignment: The main part (PCF85) and substitute part (PCF8564) share the same base product family designation, indicating core design compatibility.

Compliance Certifications: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for manufacturing and distribution.

Export Classification: Both parts carry the same ECCN (EAR99) and HTSUS code (8542.39.0001), confirming trade compliance equivalence.

The primary distinction between the main part and substitute lies in product status (obsolete versus active) and packaging format (uncased die versus bulk die), with the substitute offering active availability and standardized packaging.

Parameter Comparison

Engineering Selection Recommendations

The PCF8564AU/5BB/1,01 serves as the direct substitute for the obsolete PCF8564AU/5BD/1,01 based on the following engineering criteria:

Regulatory Compliance: Both parts maintain identical ROHS3 and REACH compliance status, ensuring no regulatory barriers to substitution in manufacturing environments subject to these standards.

Supply Chain Status: The substitute part carries active product status with confirmed inventory availability (879 Pcs New Original In Stock), whereas the main part is obsolete. This distinction is critical for procurement planning and long-term design support.

Manufacturer Continuity: NXP USA Inc. manufactures both parts, maintaining design lineage and technical support consistency.

Trade Classification Alignment: Identical ECCN and HTSUS codes confirm that substitution does not alter export or tariff classification requirements.

Selection of the substitute part is appropriate for new designs, redesigns of existing products, and component replenishment where the obsolete part is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can PCF8564AU/5BB/1,01 be used as a direct replacement for PCF8564AU/5BD/1,01?

A: Yes. Both parts are manufactured by NXP USA Inc., belong to the same Clock/Timing category, and share the same base product family (PCF8564). Both maintain ROHS3 compliance and identical trade classifications. The substitute part is currently in active production with available inventory.

Q: What is the difference between the packaging designations 5BD and 5BB?

A: The packaging suffix indicates the die format and delivery method. The 5BD designation refers to uncased die, while 5BB refers to bulk die packaging. Both are die-level components; the difference reflects packaging and handling specifications rather than functional performance.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical ROHS3 compliance status, REACH Unaffected designation, EAR99 export classification, and HTSUS code (8542.39.0001). Substitution does not introduce regulatory compliance changes.

Q: Why is the main part listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, production economics, and product lifecycle management. The substitute part (PCF8564AU/5BB/1,01) represents the active equivalent within the same product family.

Q: What parameters determine substitution eligibility for RTC/Clock components?

A: For this product category, substitution is determined by manufacturer consistency, functional category alignment, base product family designation, compliance certifications (ROHS, REACH), and trade classification codes. Electrical specifications (voltage, temperature range, interface type) are secondary considerations when the primary parameters align.

Q: Is inventory availability a factor in component substitution?

A: Inventory availability is a practical consideration for procurement but not a technical substitution criterion. The substitute part has confirmed active inventory (879 Pcs), whereas the main part is obsolete and subject to limited availability through legacy channels.
