Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7132SA20PDG is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Memory capacity: 16Kbit
• Memory organization: 2K x 8
• Access time: 20 ns
• Write cycle time: 20 ns
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C
• Memory interface: Parallel
• Technology: SRAM dual-port asynchronous

Mechanical Compatibility Considerations:

• Package type and pin count determine physical fit
• Mounting type (through-hole vs. surface mount) affects PCB integration method
• Pin configuration must align with circuit board layout

The 7132LA20JG qualifies as an electrical equivalent based on identical memory specifications, access timing, voltage supply, and temperature range. However, this substitute employs surface-mount packaging (52-PLCC) rather than through-hole packaging (48-DIP), requiring PCB redesign or adapter solutions for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

Electrical Compatibility: The 7132LA20JG provides complete electrical equivalence to the 7132SA20PDG across all memory specifications, timing parameters, and voltage/temperature operating ranges. Both devices implement identical 16Kbit dual-port asynchronous SRAM architecture with 2K x 8 organization and 20 ns access timing.

Product Status Advantage: The 7132LA20JG holds active product status with Renesas Electronics Corporation, ensuring continued availability and manufacturing support. The 7132SA20PDG is classified as obsolete, presenting long-term supply risk.

Compliance & Certification: The 7132LA20JG is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Compliance status for the 7132SA20PDG is not specified in available documentation.

Packaging Consideration: Direct pin-for-pin substitution is not possible due to package type difference. The 7132SA20PDG uses 48-DIP through-hole packaging, while the 7132LA20JG uses 52-PLCC surface-mount packaging. PCB redesign or mechanical adapter solutions are required for integration.

Frequently Asked Questions (FAQ)

Q: Can the 7132LA20JG replace the 7132SA20PDG in existing circuit boards?

A: Electrical substitution is valid based on identical memory specifications and timing parameters. However, physical substitution requires PCB modification or adapter hardware due to different package types (48-DIP through-hole vs. 52-PLCC surface-mount). The pin count also differs (48 pins vs. 52 pins).

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: memory capacity (16Kbit), memory organization (2K x 8), access time (20 ns), write cycle time (20 ns), supply voltage range (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), and memory interface type (parallel). All these parameters must match exactly between the original and substitute part.

Q: Why is the 7132LA20JG recommended over the 7132SA20PDG?

A: The 7132LA20JG is recommended because it maintains electrical equivalence while offering active product status, ensuring long-term availability. The 7132SA20PDG is obsolete, creating supply uncertainty. Additionally, the 7132LA20JG meets current environmental compliance standards (ROHS3, REACH).

Q: Are there pin-compatible alternatives to the 7132SA20PDG?

A: The provided substitute list contains only the 7132LA20JG. This part is electrically equivalent but not pin-compatible due to package type difference. Pin-compatible alternatives within the 48-DIP through-hole package format are not listed in the available substitute data.

Q: What is the difference between 48-DIP and 52-PLCC packaging?

A: 48-DIP (Dual In-line Package) is a through-hole package with 48 pins arranged in two parallel rows, measuring 0.600" (15.24mm) in width. 52-PLCC (Plastic Leaded Chip Carrier) is a surface-mount package with 52 J-lead pins arranged around the perimeter, measuring 19.13mm x 19.13mm. These packages require different PCB footprints and assembly methods.

Q: Is the 7132LA20JG suitable for new designs?

A: Yes. The 7132LA20JG is classified as an active product with current manufacturing support. It meets ROHS3 and REACH compliance requirements, making it suitable for new designs requiring 16Kbit dual-port asynchronous SRAM with 20 ns access timing and 4.5V ~ 5.5V supply voltage operation.
