Equivalent & Substitute Parts Reference: 7130LA55J/2930

Part Overview

The 7130LA55J/2930 from Renesas Electronics Corporation is an obsolete IC SRAM 8KBIT PARALLEL 52PLCC Memory product. It is a dual-port, asynchronous SRAM IC with 8Kbit capacity, a parallel interface, and a 55 ns access time, provided in a 52-PLCC (19.13x19.13) surface-mount package. Due to its obsolete product status, identifying functionally and mechanically equivalent substitute parts with matching electrical and regulatory characteristics is necessary for continued design-in and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Direct substitute parts are grouped by strict equivalency in all primary electrical, mechanical, and interface parameters, including memory type, technology, capacity, speed grades (write cycle time and access time), voltage range, temperature rating, package type and mounting, and memory organization. Substitute parts are included only if all these parameters are identical to the original part.

Parameter Comparison

Engineering Selection Recommendations

The 7130LA55JG/2930 offers equivalent electrical and mechanical parameters compared to the 7130LA55J/2930. The 7130LA55JG/2930 has an active product status and ROHS3 compliance, while the original part is obsolete and RoHS non-compliant. Selection of the 7130LA55JG/2930 is supported strictly based on identical functional parameters, improved regulatory compliance, and continued product availability.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to select a substitute for 7130LA55J/2930?
A1: Substitute parts must have identical memory type (volatile SRAM), memory format, technology (dual port, asynchronous), capacity (8Kbit), organization (1K x 8), interface (parallel), cycle and access times (55ns), voltage range (4.5V ~ 5.5V), temperature rating (0°C ~ 70°C), package (52-LCC J-Lead, 52-PLCC 19.13x19.13), and mounting type (surface mount).

Q2: Is the package and pinout identical between 7130LA55J/2930 and 7130LA55JG/2930?
A2: Both parts share the same package type, footprint, and mounting configuration: 52-LCC (J-Lead), 52-PLCC (19.13x19.13).

Q3: How does compliance status affect component selection?
A3: The 7130LA55J/2930 is RoHS non-compliant, while the 7130LA55JG/2930 is ROHS3 Compliant, supporting use in lead-free applications where regulatory compliance is required.

Q4: Are there differences in voltage, speed, or capacity between the main and substitute parts?
A4: The electrical parameters for voltage, speed, and memory capacity are identical between the main and substitute parts.

Q5: Should operating temperature range or moisture sensitivity be a concern?
A5: Both parts specify an operating temperature of 0°C ~ 70°C (TA) and MSL 3 (168 Hours), maintaining equivalency for those requirements.
