Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS82C59A-12 is determined by the following critical parameters:

• Package compatibility: 28-PLCC (11.51x11.51) surface mount configuration
• Electrical specifications: 4.5V to 5.5V supply voltage range
• Functional classification: System bus interface
• Mechanical fit: 28-LCC (J-Lead) package case

The CS82C59A-12Z qualifies as a direct substitute based on identical electrical ratings, package geometry, mounting type, and interface functionality. Both parts share the same base product number (82C59A) and are manufactured by Renesas Electronics Corporation.

Parameter Comparison

Engineering Selection Recommendations

The CS82C59A-12Z is the qualified substitute for the obsolete CS82C59A-12. Both parts maintain identical electrical and mechanical specifications, ensuring direct compatibility in system bus interface applications.

The primary distinction between these parts is product status and regulatory compliance. The CS82C59A-12Z is currently in active production status, whereas the CS82C59A-12 is obsolete. Additionally, the CS82C59A-12Z meets ROHS3 compliance requirements, while the original part does not comply with RoHS standards.

For new designs or component replenishment, the CS82C59A-12Z is the appropriate selection. For legacy system maintenance requiring exact original specifications, the CS82C59A-12 remains functionally equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the CS82C59A-12Z be used as a direct replacement for the CS82C59A-12?

A: Yes. Both parts share identical electrical ratings (4.5V to 5.5V supply), package configuration (28-PLCC), mounting type (surface mount), and system bus interface functionality. The CS82C59A-12Z is the active production equivalent.

Q: What is the difference between these two part numbers?

A: The CS82C59A-12Z differs in product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant). Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 28-PLCC (11.51x11.51) package with 28-LCC (J-Lead) case configuration. Pinout and mechanical fit are identical.

Q: What is the MSL rating for these parts?

A: Both parts carry an MSL rating of 3 with a 168-hour floor life. Standard moisture control procedures apply during storage and handling.

Q: Is the CS82C59A-12Z suitable for new product designs?

A: Yes. The CS82C59A-12Z is in active production status and meets current ROHS3 compliance requirements, making it suitable for new designs and long-term component availability.
