Renesas Electronics 7142SA100P SRAM Equivalent & Substitute Parts

Part Overview

The 7142SA100P is a 16Kbit dual-port asynchronous SRAM manufactured by Renesas Electronics Corporation in a 48-DIP package. This memory IC operates with a 100 ns access time and supports parallel data interfaces across a 2K x 8 memory organization. The part is classified as obsolete, making substitute components necessary for ongoing system support and new design implementations. Identifying electrically and mechanically compatible alternatives ensures continuity in applications requiring this memory architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7142SA100P is based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Memory capacity: 16Kbit
• Memory organization: 2K x 8
• Technology: SRAM dual-port asynchronous
• Access time: 100 ns
• Write cycle time: 100 ns
• Supply voltage range: 4.5V ~ 5.5V
• Package: 48-DIP form factor
• Mounting: Through hole

The 7132LA100CB meets all electrical specifications and maintains mechanical compatibility through identical package dimensions. The primary distinction is product status: the 7142SA100P is obsolete while the 7132LA100CB is active, with extended operating temperature range and improved moisture sensitivity characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 7132LA100CB is the direct substitute for the 7142SA100P based on electrical equivalence and mechanical compatibility. Selection of the 7132LA100CB is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical electrical specifications across all critical memory parameters
• Mechanical compatibility through matching 48-DIP package dimensions
• Extended operating temperature range (-55°C ~ 125°C) providing broader application flexibility compared to the original part's 0°C ~ 70°C range
• Improved moisture sensitivity rating (MSL 1 vs. MSL 3) reducing handling and storage constraints
• Equivalent REACH and HTSUS classifications maintaining regulatory alignment

Both parts carry RoHS non-compliant status and are subject to identical trade classification codes, confirming regulatory equivalence for substitution purposes.

Frequently Asked Questions (FAQ)

Q: Can the 7132LA100CB directly replace the 7142SA100P in existing designs?

A: Yes. Both parts share identical memory capacity (16Kbit), organization (2K x 8), access time (100 ns), write cycle time (100 ns), supply voltage range (4.5V ~ 5.5V), and 48-DIP package dimensions. Electrical and mechanical compatibility is complete.

Q: What is the primary advantage of using the 7132LA100CB over the 7142SA100P?

A: The 7132LA100CB is an active product with extended operating temperature range (-55°C ~ 125°C versus 0°C ~ 70°C) and superior moisture sensitivity characteristics (MSL 1 versus MSL 3). These improvements provide enhanced reliability and reduced handling constraints.

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

A: No. Both parts deliver identical access time, write cycle time, and supply voltage specifications. Performance in parallel memory interface applications is equivalent.

Q: Does the package change affect PCB layout or assembly?

A: No. Both parts use the 48-DIP package with identical 0.600" (15.24mm) dimensions and through-hole mounting. PCB layouts and assembly processes require no modification.

Q: What is the inventory status for the substitute part?

A: The 7132LA100CB is available with 903 pieces in new original stock, ensuring immediate procurement availability.
