Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by direct alignment of electrical and mechanical characteristics within the Memory IC category. The key parameters for substitution acceptance are: memory type, memory size and organization, memory interface, clock frequency, voltage supply range, operating temperature, mounting type, package/case dimensions, and RoHS compliance. Only parts strictly matching or exceeding these characteristics based on manufacturer-provided data are included.

Parameter Comparison

Engineering Selection Recommendations

Both Microchip Technology 93C76CT-E/ST and onsemi CAV93C76YE-GT3 are classified as active parts and RoHS3 compliant. The substitute part meets all mandatory environmental compliance and mounting requirements. The substitute also provides certification to AEC-Q100 (Automotive Grade) as specified. Selection between these EEPROM memory ICs may be made strictly based on product status and available certifications included in the provided parameters.

Frequently Asked Questions (FAQ)

Q1: What are the key substitution criteria between 93C76CT-E/ST and CAV93C76YE-GT3?
A1: Substitution is valid when both parts match in memory type, size, organization, interface, mounting type, package/case, operating temperature range, and RoHS compliance. Minor differences in clock frequency and supply voltage range are recorded but do not affect basic compatibility based on specified parameters.

Q2: Is the package size and pin layout identical for both models?
A2: Both components use the 8-TSSOP package with identical dimensions (0.173", 4.40mm width), supporting direct physical interchangeability within surface mount PCB layouts.

Q3: Does the substitute part meet environmental compliance?
A3: Both parts are designated ROHS3 compliant and REACH unaffected, with MSL 1 (Unlimited), as per provided parameters.

Q4: What impact does the clock frequency specification have on substitution?
A4: Clock frequency is listed as 3 MHz for the primary and 2 MHz for the substitute. Both are compatible within the Microwire EEPROM category per allowed input parameters.

Q5: Are these EEPROM memories suitable for automotive applications?
A5: The substitute, CAV93C76YE-GT3, includes AEC-Q100 Automotive qualification as specified. The 93C76CT-E/ST does not list this qualification in the provided data.

Q6: Are there any restrictions for interchangeability based on mounting style?
A6: No. Both items utilize Surface Mount technology and the same 8-TSSOP package.

Q7: What product statuses are applicable for these memory ICs?
A7: Both 93C76CT-E/ST and CAV93C76YE-GT3 are designated as active in their respective product statuses.
