Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPCQ128SI16N is determined by strict equivalence across the following parameters:

• Memory capacity: 128MB
• Programmable interface: In System Programmable
• Supply voltage range: 2.7V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• Physical package: 16-SOIC (0.295", 7.50mm Width)
• Moisture sensitivity classification: MSL 3

The EPCQ128ASI16N meets all these criteria and is classified as an active product within the EPCQ-A series, providing a direct functional replacement for the obsolete EPCQ128SI16N.

Frequently Asked Questions (FAQ)

Q: Can the EPCQ128ASI16N be used as a direct replacement for the EPCQ128SI16N?

A: Yes. The EPCQ128ASI16N provides functional equivalence across all specified electrical and mechanical parameters, including memory capacity, supply voltage, operating temperature range, and 16-SOIC package configuration.

Q: Are there differences in programmability between these parts?

A: No. Both the EPCQ128SI16N and EPCQ128ASI16N support in-system programmability with identical voltage and temperature specifications.

Q: What is the significance of the product status difference?

A: The EPCQ128SI16N is classified as obsolete, while the EPCQ128ASI16N is active. This means the EPCQ128ASI16N is currently manufactured and supported, making it the appropriate choice for new designs and ongoing system support.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both parts are classified as MSL 3 with a 168-hour rating, requiring identical handling and storage protocols.

Q: Does the RoHS compliance of the EPCQ128ASI16N affect compatibility?

A: No. RoHS compliance is an environmental and regulatory attribute that does not affect electrical or mechanical compatibility. The EPCQ128ASI16N's RoHS compliance status provides additional regulatory alignment without impacting functional equivalence.
