Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE8203EXUMA1 is determined by the following critical parameters:

Voltage Supply Range: The substitute must operate within or encompass the 8V to 20V supply voltage specification of the original part.

Operating Temperature Range: The substitute must maintain functionality across the -40°C to 150°C operating window required for automotive applications.

Automotive Grade Classification: The substitute must carry automotive-grade qualification to meet the same reliability and qualification standards.

Package Compatibility: The substitute must utilize a 36-pin surface-mount package with exposed pad configuration suitable for the same PCB footprint and thermal management requirements.

Moisture Sensitivity Level: The substitute must maintain MSL 3 classification or better to ensure equivalent handling and storage requirements.

Regulatory Compliance: The substitute must maintain REACH Unaffected status and EAR99 ECCN classification for equivalent regulatory compliance.

The L9951XPTR from STMicroelectronics meets these substitution criteria within the allowed parameter specifications.

Parameter Comparison

The supply current specification of the L9951XPTR is 7mA compared to 1mA for the original part. Both components utilize 36-pin surface-mount packages with exposed pad configurations suitable for thermal management in automotive applications.

Selection of the L9951XPTR is supported by its active product status, ensuring long-term availability and continued manufacturer support for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can the L9951XPTR directly replace the TLE8203EXUMA1 in existing designs?

A: The L9951XPTR meets the critical substitution parameters: automotive-grade classification, identical operating temperature range (-40°C to 150°C), MSL 3 moisture sensitivity, and 36-pin surface-mount package configuration with exposed pad. The supply voltage range of the L9951XPTR (7V to 28V) encompasses the original specification (8V to 20V). PCB footprint compatibility requires verification based on specific package dimensions and pin assignments.

Q: What are the key differences between these parts?

A: The primary differences are product status (L9951XPTR is active; TLE8203EXUMA1 is obsolete), supply voltage range (L9951XPTR: 7V to 28V; TLE8203EXUMA1: 8V to 20V), and supply current specification (L9951XPTR: 7mA; TLE8203EXUMA1: 1mA). Both maintain identical operating temperature ranges and automotive-grade qualification.

Q: Are the package configurations compatible?

A: Both parts utilize 36-pin surface-mount packages with exposed pad configurations. The TLE8203EXUMA1 uses 36-BSSOP packaging, while the L9951XPTR uses PowerSSO-36 packaging. Physical footprint compatibility requires detailed comparison of pin pitch, pad dimensions, and thermal pad specifications.

Q: What regulatory compliance is maintained?

A: Both the TLE8203EXUMA1 and L9951XPTR maintain REACH Unaffected status and EAR99 ECCN classification, ensuring equivalent regulatory compliance for automotive applications.

Q: Why is the TLE8203EXUMA1 classified as obsolete?

A: Obsolete classification indicates that the manufacturer has discontinued production and support for this component. The L9951XPTR, classified as active, represents the current manufacturing alternative with ongoing support.
