Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLE4290GATMA1 are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

• Fixed 5V output voltage configuration
• 450mA output current capability
• Maximum input voltage of 42V
• 0.5V maximum dropout voltage at 300mA
• 60dB PSRR at 100Hz
• Operating temperature range of -40°C to 150°C
• Automotive-grade qualification with AEC-Q100 certification
• Identical package form factor: TO-263-6 (D2PAK, 5 Leads + Tab)
• Surface mount mounting type

The identified substitutes meet these core electrical specifications and package requirements, enabling direct functional replacement in applications designed for the TLE4290GATMA1.

Parameter Comparison

Engineering Selection Recommendations

NCV4275ADS50R4G (onsemi): This substitute meets all core electrical and mechanical specifications. The part carries AEC-Q100 automotive qualification and operates within the required temperature range. Product status is listed as Not For New Designs. Quiescent current is 200 µA, which is lower than the original 230 µA specification. RoHS3 compliance is confirmed.

TLE4275QKTTRQ1 (Texas Instruments): This substitute satisfies all electrical parameters and package requirements with identical dropout voltage, PSRR, and temperature range specifications. The part maintains Active product status, indicating ongoing manufacturer support. Quiescent current is 200 µA. RoHS3 compliance is confirmed. Current supply maximum is 22 mA, compared to 25 mA for the original part.

For applications requiring long-term component availability and manufacturer support, TLE4275QKTTRQ1 is the preferred selection due to its Active product status. Both substitutes are qualified to AEC-Q100 automotive standards and are packaged identically to the original TLE4290GATMA1.

Frequently Asked Questions (FAQ)

Q: Can NCV4275ADS50R4G directly replace TLE4290GATMA1 in existing designs?

A: Yes. Both parts share identical output voltage (5V), output current (450mA), input voltage rating (42V), dropout voltage (0.5V @ 300mA), PSRR (60dB @ 100Hz), operating temperature range (-40°C to 150°C), and package form factor (TO-263-6 D2PAK). Both carry AEC-Q100 automotive qualification.

Q: What is the difference in quiescent current between the original and substitute parts?

A: The TLE4290GATMA1 specifies 230 µA quiescent current, while both NCV4275ADS50R4G and TLE4275QKTTRQ1 specify 200 µA. This represents a 30 µA reduction in standby current consumption, which is favorable for power-sensitive applications.

Q: Why is TLE4275QKTTRQ1 recommended over NCV4275ADS50R4G?

A: TLE4275QKTTRQ1 maintains Active product status, indicating ongoing manufacturer support and availability. NCV4275ADS50R4G is designated Not For New Designs. Both parts meet all electrical and mechanical requirements; the recommendation is based on long-term component lifecycle considerations.

Q: Are all substitute parts RoHS compliant?

A: NCV4275ADS50R4G and TLE4275QKTTRQ1 are both ROHS3 compliant. The original TLE4290GATMA1 does not specify RoHS status in the provided data.

Q: Do the substitute parts require PCB layout modifications?

A: No. All parts use the identical TO-263-6 (D2PAK, 5 Leads + Tab) package, enabling direct PCB substitution without layout changes.

Q: What protection features are common across all three parts?

A: Over-temperature and reverse polarity protection are present in all three regulators. Over-current and short-circuit protection are specified for TLE4290GATMA1 and TLE4275QKTTRQ1. NCV4275ADS50R4G specifies over-temperature and reverse polarity protection.
