AS7C32098A-15TCN Equivalent & Substitute Parts

Part Overview

The AS7C32098A-15TCN is a 2Mbit asynchronous SRAM manufactured by Alliance Memory, Inc., configured as 128K x 16 with parallel interface architecture. This component is actively produced and widely used in applications requiring volatile memory with fast access times. The part is housed in a 44-TSOP surface mount package and operates within the 3V to 3.6V supply range with a 15 ns access time specification.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits acceptance of alternative electrical characteristics within defined tolerance bands.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS7C32098A-15TCN is determined by strict alignment across the following critical parameters:

• Memory capacity and organization (2Mbit, 128K x 16 configuration)
• Parallel interface architecture
• 44-TSOP surface mount package footprint compatibility
• Supply voltage compatibility within the 3V to 3.6V operating window
• RoHS3 compliance status
• Moisture sensitivity level (MSL 3)

The IS62WV12816BLL-55TLI qualifies as a functional substitute based on matching memory size, organization, interface type, and package specification. The extended access time (55 ns versus 15 ns) and broader operating temperature range represent parameter differences that must be evaluated against specific application timing requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the AS7C32098A-15TCN and IS62WV12816BLL-55TLI maintain active production status and full RoHS3 compliance, ensuring long-term availability and regulatory alignment. The primary differentiation lies in access time specification and operating temperature envelope.

Selection of the IS62WV12816BLL-55TLI as a substitute is appropriate when application timing budgets accommodate the 55 ns access time specification. The extended temperature operating range (-40°C to 85°C) provides operational flexibility beyond the primary part's 0°C to 70°C window. Both components share identical memory capacity, organization, package footprint, and MSL rating, ensuring mechanical and thermal compatibility.

The AS7C32098A-15TCN remains the preferred selection for applications with strict 15 ns access time requirements or operating temperature constraints below 0°C or above 70°C.

Frequently Asked Questions (FAQ)

Q: Can the IS62WV12816BLL-55TLI directly replace the AS7C32098A-15TCN in existing PCB designs?

A: Yes, from a mechanical and electrical interface perspective. Both components use identical 44-TSOP package geometry and share the same pin configuration for 128K x 16 parallel SRAM architecture. Pin-level compatibility is confirmed.

Q: What is the impact of the 40 ns access time difference between these parts?

A: The IS62WV12816BLL-55TLI operates at 55 ns access time compared to the AS7C32098A-15TCN at 15 ns. Applications with timing-critical read/write cycles must verify that system timing margins accommodate this extended latency. Non-timing-critical applications experience no functional impact.

Q: Are there voltage supply compatibility concerns?

A: The IS62WV12816BLL-55TLI accepts a broader supply voltage range (2.5V to 3.6V) compared to the AS7C32098A-15TCN (3V to 3.6V). Both operate correctly within the 3V to 3.6V window. The substitute part provides additional flexibility for lower voltage applications.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both components are ROHS3 compliant, carry MSL 3 moisture sensitivity ratings, and maintain active product status. REACH and ECCN classifications are identical.

Q: What inventory considerations apply to these parts?

A: The AS7C32098A-15TCN maintains 1121 pieces in stock. The IS62WV12816BLL-55TLI has 17663 pieces available, providing significantly higher inventory availability for immediate procurement needs.
