Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7290820PQF is determined by the following core parameters:

• Functional Equivalence: Identical circuit configuration (1 x 16:16 multiplexer topology)
• Electrical Compatibility: Matching voltage supply range (4.75V ~ 5.25V single supply)
• Temperature Rating: Identical operating temperature range (-40°C ~ 85°C)
• Manufacturer Continuity: Same manufacturer (Renesas Electronics Corporation) within the same product series (7200)
• Base Product Number: Shared base product number (7290820) indicating functional equivalence

The substitute part 7290820JG meets all substitution criteria. While the package format differs (84-PLCC versus 100-PQFP), the electrical and functional specifications remain identical, making it a valid alternative for applications where PCB layout can accommodate the different package geometry.

Parameter Comparison

Engineering Selection Recommendations

The 7290820JG is the manufacturer-recommended substitute for the obsolete 7290820PQF. Both parts share identical electrical specifications and functional topology within the Renesas 7200 series multiplexer family.

Product Status Consideration: The 7290820JG maintains active product status with current manufacturing support, whereas the 7290820PQF is obsolete. For new designs or long-term production continuity, the 7290820JG is the appropriate selection.

Compliance Status: The 7290820JG achieves ROHS3 compliance, whereas the 7290820PQF is non-compliant. Applications subject to RoHS regulatory requirements must use the 7290820JG.

Package Transition: The primary design consideration is the package format change from 100-PQFP to 84-PLCC. PCB layout modifications are required to accommodate the different pin count and footprint geometry. Pin-to-pin functional mapping must be verified against device datasheets prior to implementation.

Frequently Asked Questions (FAQ)

Q: Are the 7290820PQF and 7290820JG electrically interchangeable?

A: Yes. Both parts operate on identical voltage supply ranges (4.75V ~ 5.25V), support the same circuit configuration (1 x 16:16 multiplexer), and maintain identical temperature ratings (-40°C ~ 85°C). Electrical functionality is equivalent.

Q: What is the primary difference between these parts?

A: The main difference is packaging format. The 7290820PQF uses 100-PQFP (20x14mm), while the 7290820JG uses 84-PLCC (29.31x29.31mm). This requires PCB redesign for footprint compatibility.

Q: Why is the 7290820PQF obsolete?

A: The 7290820PQF is classified as obsolete by Renesas Electronics. The 7290820JG represents the active product continuation within the same functional family.

Q: Can I use the 7290820JG as a direct replacement without PCB modification?

A: No. The different package formats (100-PQFP versus 84-PLCC) require PCB layout changes. Pin assignments must be verified against the respective device datasheets to ensure correct signal routing.

Q: What is the MSL rating, and does it differ between parts?

A: Both parts carry MSL rating 3 (168 Hours), indicating identical moisture sensitivity levels. Storage and handling requirements are equivalent.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance is a regulatory and procurement consideration, not a functional substitution criterion. The 7290820JG's ROHS3 compliance makes it preferable for applications subject to RoHS requirements, while the non-compliant 7290820PQF may be restricted in certain markets or applications.
