Engineering Selection Recommendations

Microchip Technology Parts (24VL024T/MNY, 24VL025T/MNY, AT24C02D-MAHM-T): All three parts are Active products with ROHS3 compliance. The 24VL025T/MNY is a parametric equivalent to the main part with identical electrical specifications. The AT24C02D-MAHM-T offers higher clock frequency (1 MHz) and wider operating temperature range (-40°C ~ 85°C) but operates at lower access time (4.5 µs) and requires minimum supply voltage of 1.7V.

onsemi Parts (CAT34C02VP2IGT4A, CAT34C02HU4IGT4A): Both are Active products with ROHS3 compliance. CAT34C02VP2IGT4A maintains the 8-TDFN package format with identical electrical performance to the main part. CAT34C02HU4IGT4A uses 8-UDFN-EP packaging. Both support wider voltage range (1.7V ~ 5.5V) and extended operating temperature (-40°C ~ 85°C).

STMicroelectronics Parts (M24C02-RMC6TG, M24C02-FMC6TG): Both are Active products with ROHS3 compliance and identical I2C electrical specifications. M24C02-RMC6TG requires minimum supply voltage of 1.8V, while M24C02-FMC6TG supports 1.7V minimum. Both support extended operating temperature range (-40°C ~ 85°C).

Rohm Semiconductor Part (BR24L02NUX-WTR): Active product with ROHS3 compliance and verified DiGi-Electronics programmability. Supports widest voltage range (1.8V ~ 5.5V) and extended operating temperature (-40°C ~ 85°C). Uses VSON008X2030 package format.

Frequently Asked Questions (FAQ)

Q: Can I use AT24C02D-MAHM-T as a direct replacement for 24VL024T/MNY?

A: AT24C02D-MAHM-T is electrically compatible but operates at higher clock frequency (1 MHz vs. 400 kHz) and faster access time (4.5 µs vs. 900 ns). The minimum supply voltage requirement is 1.7V instead of 1.5V. Verify your circuit design operates within 1.7V ~ 3.6V range before substitution.

Q: What is the difference between 8-TDFN, 8-UDFN, and 8-UFDFPN packages?

A: All three are 8-pin surface mount packages with 2x3 mm footprints and exposed pads. TDFN (Thin Dual Flat No-Lead), UDFN (Ultra Dual Flat No-Lead), and UFDFPN (Ultra Flat Dual Flat Package No-Lead) are functionally equivalent for I2C EEPROM applications. PCB layout compatibility depends on your specific design; verify pad dimensions and thermal via requirements with component datasheets.

Q: Is CAT34C02VP2IGT4A a pin-for-pin replacement?

A: Yes. CAT34C02VP2IGT4A maintains the 8-TDFN (2x3) package with identical pinout and electrical interface. It supports the same I2C protocol at 400 kHz clock frequency with 900 ns access time.

Q: Why does BR24L02NUX-WTR support 5.5V maximum supply when the main part supports only 3.6V?

A: BR24L02NUX-WTR is designed for broader voltage compatibility. If your circuit operates at 3.6V or below, this part is fully compatible. The higher voltage rating provides flexibility for applications requiring extended supply range.

Q: Can I substitute M24C02-RMC6TG if my circuit requires 1.5V minimum supply?

A: No. M24C02-RMC6TG requires minimum supply voltage of 1.8V. If your circuit operates below 1.8V, use 24VL025T/MNY, CAT34C02VP2IGT4A, or M24C02-FMC6TG instead.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the main part.
