Engineering Selection Recommendations

The MAX2645EUB+ is the direct substitute for the obsolete MAX2645EUB. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical performance specifications and physical packaging. The primary distinction is product status: the MAX2645EUB+ maintains active production status, ensuring long-term availability and supply chain continuity.

Both parts comply with ROHS3 requirements and carry identical export classification (EAR99) and tariff codes. The moisture sensitivity level of 1 (Unlimited) applies to both variants, indicating no special moisture handling requirements during storage or assembly.

For new designs or system replacements requiring the MAX2645EUB, the MAX2645EUB+ is the appropriate selection due to its active product status and equivalent electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the MAX2645EUB+ be used as a direct replacement for the MAX2645EUB?

A: Yes. The MAX2645EUB+ is electrically and mechanically identical to the MAX2645EUB. Both parts operate at 3.4GHz to 3.8GHz with 14.4dB gain, 2.3dB to 3dB noise figure, and -5dBm P1dB. The package, pinout, and mounting configuration are identical. The primary difference is that MAX2645EUB+ maintains active product status.

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

A: The MAX2645EUB is classified as obsolete, indicating discontinued production. The MAX2645EUB+ is active, meaning it remains in production with ongoing manufacturer support and availability. For applications requiring long-term component supply, the active MAX2645EUB+ is the preferred choice.

Q: Are there packaging differences between these parts?

A: Both parts use the same 10-TFSOP/10-MSOP package with 0.118" width and exposed pad. The main packaging difference is that MAX2645EUB is supplied in standard packaging while MAX2645EUB+ is supplied in tube packaging. Both are surface mount configurations suitable for automated assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MAX2645EUB and MAX2645EUB+ are ROHS3 compliant, carry EAR99 export classification, and share the same HTSUS tariff code (8542.33.0001). Moisture sensitivity level is 1 (Unlimited) for both variants.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching frequency range (3.4GHz ~ 3.8GHz), gain (14.4dB), noise figure (2.3dB ~ 3dB), P1dB (-5dBm), supply voltage (3V ~ 5.5V), and supply current (9.2mA ~ 10.9mA). The MAX2645EUB+ meets all these parameters identically.
