Equivalent & Substitute Parts for 7202LA12J8

Part Overview

The 7202LA12J8 is an asynchronous FIFO logic integrated circuit with 9K memory capacity (1K x 9 organization), designed for uni-directional data buffering applications. This device operates at 50MHz with a 12ns access time and is housed in a 32-PLCC surface mount package. The part is currently classified as obsolete, making identification of compatible substitute components essential for ongoing system support and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the 7202LA12J8 is determined by strict equivalence across the following critical parameters:

• Memory organization: 1K x 9 (9K total capacity)
• FIFO function: Asynchronous operation
• Electrical performance: 50MHz data rate, 12ns access time
• Power supply: 4.5V to 5.5V operating range
• Current consumption: 80mA maximum
• Data path: Uni-directional configuration
• Physical form factor: 32-PLCC surface mount package (14x11.46mm)
• Temperature rating: 0°C to 70°C

The 7202LA12JG8 meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is packaging format (bulk versus tape & reel) and product lifecycle status.

Engineering Selection Recommendations

The 7202LA12JG8 is the direct substitute for the 7202LA12J8. Both parts share identical electrical specifications, memory organization, and physical package dimensions. Selection between these parts should be based on the following factors:

Product Lifecycle: The 7202LA12J8 is obsolete, while the 7202LA12JG8 maintains active product status with confirmed inventory availability. For new designs or long-term system support, the 7202LA12JG8 is the appropriate choice.

Regulatory Compliance: The 7202LA12JG8 is ROHS3 compliant, whereas the 7202LA12J8 is RoHS non-compliant. Applications subject to RoHS requirements must use the 7202LA12JG8.

Packaging Considerations: The 7202LA12J8 is supplied in bulk packaging, while the 7202LA12JG8 is supplied in tape & reel format. Tape & reel packaging is standard for automated assembly processes and provides superior component protection during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the 7202LA12JG8 be used as a direct replacement for the 7202LA12J8 in existing designs?

A: Yes. The 7202LA12JG8 is electrically and mechanically equivalent to the 7202LA12J8. All electrical parameters, memory specifications, and package dimensions are identical. The parts are pin-compatible and functionally interchangeable.

Q: What is the difference between the bulk and tape & reel packaging formats?

A: Bulk packaging supplies individual components in standard packaging, while tape & reel format winds components onto continuous carrier tape for automated pick-and-place assembly. Tape & reel is the standard format for high-volume manufacturing and provides better component protection.

Q: Why is RoHS compliance important for this substitution?

A: RoHS (Restriction of Hazardous Substances) compliance is a regulatory requirement in many markets. The 7202LA12JG8 meets ROHS3 standards, making it suitable for applications with RoHS compliance mandates. The 7202LA12J8 does not meet these requirements.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts have identical electrical specifications: 50MHz data rate, 12ns access time, 4.5V to 5.5V supply voltage, and 80mA maximum current consumption.

Q: What is the moisture sensitivity level difference between these parts?

A: The 7202LA12J8 has MSL 1 (unlimited shelf life), while the 7202LA12JG8 has MSL 3 (168 hours maximum). MSL 3 requires controlled storage conditions and baking procedures before assembly. Standard industrial storage practices accommodate MSL 3 requirements.
