Equivalent & Substitute Parts for 71V424L15PHGI

Part Overview

The Renesas Electronics 71V424L15PHGI is a 4Mbit asynchronous SRAM with parallel interface, organized as 512K x 8, housed in a 44-TSOP II package. This volatile memory device operates at 3V to 3.6V supply voltage with a 15 ns access time and write cycle time. The part is active in production status and fully RoHS3 compliant. Substitute parts are identified for applications requiring equivalent memory capacity, interface type, and package compatibility, or where improved performance specifications are needed.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 71V424L15PHGI are qualified based on the following criteria:

• Memory capacity: 4Mbit
• Memory organization: 512K x 8
• Interface type: Parallel
• Package: 44-TSOP or 44-TSOP II
• Mounting: Surface Mount
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance
• MSL rating: 3 (168 Hours)
• Supply voltage compatibility within specified ranges

Substitute parts may offer improved access time and write cycle time specifications while maintaining full compatibility with the original part's electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status and full RoHS3 compliance with identical MSL ratings. The AS7C34096A-12TIN provides improved timing performance at 12 ns while maintaining the original 3V to 3.6V supply voltage specification. The ISSI parts (IS61LV5128AL-10TLI, IS61WV5128BLL-10TLI, IS61WV5128EDBLL-10TLI) offer the fastest access and write cycle times at 10 ns. The IS61WV5128 series variants support extended lower voltage operation down to 2.4V, providing broader supply voltage compatibility. All parts are packaged in 44-TSOP or 44-TSOP II configurations suitable for direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can the AS7C34096A-12TIN replace the 71V424L15PHGI directly?

A: Yes. Both parts share identical 4Mbit capacity, 512K x 8 organization, parallel interface, and 44-TSOP package footprint. The AS7C34096A-12TIN offers faster timing (12 ns vs. 15 ns) and maintains the same 3V to 3.6V supply voltage range.

Q: What is the difference between IS61LV5128AL-10TLI and IS61WV5128BLL-10TLI?

A: Both provide 10 ns access and write cycle times in 44-TSOP II packages. The IS61WV5128BLL-10TLI supports extended lower voltage operation (2.4V to 3.6V) compared to IS61LV5128AL-10TLI (3.135V to 3.6V). Select based on your circuit's minimum supply voltage requirement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification and MSL rating 3 (168 Hours), matching the original part's environmental and regulatory status.

Q: Can I use a faster substitute part in place of the 71V424L15PHGI?

A: Yes. Substitute parts with faster access times (12 ns or 10 ns) are backward compatible with designs specified for 15 ns operation. Verify your circuit design does not impose upper timing limits that would be violated by faster parts.

Q: What packaging considerations apply to these substitutes?

A: The 71V424L15PHGI uses 44-TSOP II packaging. The AS7C34096A-12TIN uses 44-TSOP2 packaging. Both are mechanically compatible 44-pin TSOP packages with 0.400" (10.16mm) width. Verify PCB footprint compatibility before substitution.
