Key Parameters

Substitute Part Grouping Explanation

Substitution for the 7134LA35P is determined by strict equivalence across the following critical parameters:

• Memory capacity: 32Kbit
• Memory organization: 4K x 8
• Technology: SRAM dual-port asynchronous
• Access time: 35 ns
• Write cycle time: 35 ns
• Supply voltage range: 4.5V ~ 5.5V
• Package footprint: 48-DIP (0.600", 15.24mm)
• Parallel interface architecture

The substitute part 7134LA35CB maintains identical electrical specifications and memory organization while differing in packaging format and product status. Both parts share the same base product number (7134LA) and are manufactured by Renesas Electronics Corporation.

Parameter Comparison

Engineering Selection Recommendations

The 7134LA35P is classified as obsolete. The 7134LA35CB is the manufacturer-recommended substitute, maintaining active product status with Renesas Electronics Corporation.

Electrical compatibility is confirmed across all critical parameters: memory capacity, organization, access time, write cycle time, supply voltage, and parallel interface specifications are identical. Both components are RoHS non-compliant and REACH unaffected.

The 7134LA35CB offers extended operating temperature range (-55°C ~ 125°C versus 0°C ~ 70°C) and improved moisture sensitivity characteristics (MSL 1 versus MSL 3), providing enhanced reliability for long-term applications. The physical footprint and through-hole mounting remain unchanged, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 7134LA35CB directly replace the 7134LA35P in existing designs?

A: Yes. Both parts maintain identical electrical specifications, memory organization (4K x 8), access time (35 ns), write cycle time (35 ns), supply voltage (4.5V ~ 5.5V), and 48-DIP package footprint. Through-hole mounting is identical, enabling direct PCB substitution.

Q: What are the key differences between these parts?

A: The primary differences are product status (7134LA35P is obsolete; 7134LA35CB is active), operating temperature range (7134LA35P: 0°C ~ 70°C; 7134LA35CB: -55°C ~ 125°C), moisture sensitivity level (7134LA35P: MSL 3; 7134LA35CB: MSL 1), and supplier device package designation (48-PDIP versus 48-SIDE BRAZED).

Q: Are there any compliance or certification differences?

A: Both parts are RoHS non-compliant and REACH unaffected. ECCN classifications differ (7134LA35P: EAR99; 7134LA35CB: 3A001A2C). Consult compliance requirements for your specific application and jurisdiction.

Q: Does the extended temperature range of the 7134LA35CB affect compatibility?

A: No. The extended operating temperature range (-55°C ~ 125°C) of the 7134LA35CB is a superset of the 7134LA35P specification (0°C ~ 70°C). Applications operating within the original temperature range remain fully compatible.

Q: What is the significance of the different moisture sensitivity levels?

A: The 7134LA35CB has MSL 1 (unlimited moisture exposure) compared to the 7134LA35P MSL 3 (168 hours). This indicates improved moisture resistance in the substitute part, reducing risk during storage and handling.
