Parameter Comparison

Engineering Selection Recommendations

The TLE42502GHTSA1 is the direct substitute for the obsolete IFX21401MBHTSA1. Both devices are manufactured by Infineon Technologies and maintain identical electrical specifications, output configuration, current ratings, and package geometry.

The TLE42502GHTSA1 offers three distinct advantages:

Product Status: The substitute is classified as Active, ensuring ongoing availability and manufacturing support compared to the obsolete status of the original part.

Compliance & Qualification: The TLE42502GHTSA1 carries automotive-grade qualification (AEC-Q100) and is part of the OPTIREG™ series, providing enhanced reliability documentation and supply chain stability.

Performance Improvements: The substitute features reduced quiescent current (20 µA versus 200 µA) and extended operating temperature range (-40°C to 150°C versus -40°C to 125°C), delivering superior thermal performance and lower standby power consumption.

Both parts maintain ROHS3 compliance, MSL 1 rating, and identical mechanical packaging, enabling direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can TLE42502GHTSA1 be used as a direct replacement for IFX21401MBHTSA1?

A: Yes. Both devices share identical output configuration (positive adjustable), current rating (50mA), voltage specifications (40V maximum input, 0.3V dropout), and package geometry (6-SMD, 5 Leads, Gull Wing). No circuit redesign is required for substitution.

Q: What are the key differences between these parts?

A: The primary differences are product status (Active versus Obsolete), quiescent current (20 µA versus 200 µA), operating temperature range (-40°C to 150°C versus -40°C to 125°C), and automotive qualification (AEC-Q100) in the substitute. All electrical and mechanical parameters remain equivalent.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 6-SMD (5 Leads), Gull Wing package configuration. The supplier device packages differ (PG-SCT595-5-1 versus PG-SCT595-5-2), but the physical footprint and lead configuration are identical, enabling direct PCB substitution.

Q: Does the reduced quiescent current affect circuit operation?

A: No. The 20 µA quiescent current in the TLE42502GHTSA1 is a performance improvement that reduces standby power consumption without affecting the regulator's output characteristics or control behavior. The device maintains identical voltage dropout, PSRR, and enable control functionality.

Q: Is the extended temperature range of the substitute a concern?

A: No. The extended operating range (-40°C to 150°C) of the TLE42502GHTSA1 provides additional thermal margin and is fully backward compatible with applications designed for the original -40°C to 125°C range.

Q: Are both parts RoHS compliant?

A: Yes. Both IFX21401MBHTSA1 and TLE42502GHTSA1 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting identical environmental and regulatory requirements.
