Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the EPCQ512ASI16N is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Voltage supply range (2.7V ~ 3.6V)
• Operating temperature range (-40°C ~ 85°C)
• Programmable type (In System Programmable)

Mechanical Compatibility Parameters:

• Package type (16-SOIC with 0.295" / 7.50mm width)
• Mounting type (Surface Mount)
• Moisture sensitivity level (MSL 3)

The EPCQ128ASI16N qualifies as a substitute based on matching electrical specifications, identical package configuration, and compatible programmable characteristics. Both devices operate within the same voltage and temperature parameters, utilize identical 16-SOIC packaging, and support in-system programming functionality.

Parameter Comparison

Engineering Selection Recommendations

The EPCQ128ASI16N is an active product with verified programmable functionality and RoHS compliance certification, providing advantages over the obsolete EPCQ512ASI16N for new implementations and ongoing support scenarios. Both components share identical electrical operating parameters, package dimensions, and mounting characteristics, ensuring direct compatibility at the circuit board level.

The primary design consideration is memory capacity: the EPCQ128ASI16N provides 128MB storage compared to the EPCQ512ASI16N's 512MB capacity. Selection between these devices depends on application-specific memory requirements. For applications requiring the full 512MB capacity of the original part, alternative higher-capacity devices within the EPCQ series should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the EPCQ128ASI16N directly replace the EPCQ512ASI16N in existing designs?

A: Physical and electrical compatibility is confirmed. Both devices use identical 16-SOIC packaging, operate within the same voltage range (2.7V ~ 3.6V), support the same temperature range (-40°C ~ 85°C), and feature in-system programmable functionality. The primary difference is memory capacity: 128MB versus 512MB. Substitution is valid only if application memory requirements do not exceed 128MB.

Q: What are the key compatibility parameters for EPCQ series substitution?

A: Substitution within the EPCQ series requires matching voltage supply range, operating temperature range, package type (16-SOIC), mounting type (surface mount), and programmable type (in-system programmable). Memory capacity may vary based on application requirements.

Q: Is the EPCQ128ASI16N RoHS compliant?

A: Yes, the EPCQ128ASI16N is RoHS compliant. The original EPCQ512ASI16N RoHS status is not specified in available documentation.

Q: What is the moisture sensitivity level for both parts?

A: Both the EPCQ512ASI16N and EPCQ128ASI16N have a Moisture Sensitivity Level (MSL) rating of 3, indicating a maximum floor life of 168 hours at 30°C and 60% relative humidity before baking is required.

Q: Why is the EPCQ512ASI16N listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Intel. The EPCQ128ASI16N, classified as active, represents the current available alternative within the EPCQ product line.
