Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLS202B1MBV33HTMA1 is determined by strict equivalence across the following critical parameters:

• Output voltage specification (3.3V fixed)
• Output current capability (150mA)
• Maximum input voltage rating (18V)
• Dropout voltage performance (0.57V @ 150mA)
• Package type and pinout (6-SMD, 5 Leads, Gull Wing, PG-SCT595-5-1)
• Automotive grade qualification (AEC-Q100)
• Operating temperature range (-40°C ~ 150°C)
• Protection features (Over Current, Over Temperature, Short Circuit)

The TLS202B1MBV33HTSA1 meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is product status and moisture sensitivity level.

Parameter Comparison

Engineering Selection Recommendations

The TLS202B1MBV33HTSA1 is the direct active substitute for the obsolete TLS202B1MBV33HTMA1. Both parts maintain identical electrical specifications, automotive qualification (AEC-Q100), and package configuration. The substitute part carries active product status with improved moisture sensitivity characteristics (MSL 1 vs. MSL 3), providing enhanced reliability for storage and handling in production environments. Both parts satisfy ROHS3 compliance and REACH requirements. Selection of the active substitute is appropriate for new designs and production continuity where the TLS202B1MBV33HTMA1 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the TLS202B1MBV33HTSA1 be used as a direct replacement for the TLS202B1MBV33HTMA1?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including output voltage, current rating, dropout voltage, operating temperature range, package type, and automotive qualification. The substitute is pin-compatible and functionally equivalent.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and moisture sensitivity level. The TLS202B1MBV33HTMA1 is obsolete with MSL 3 (168 hours), while the TLS202B1MBV33HTSA1 is active with MSL 1 (unlimited). The active part offers superior moisture protection during storage and handling.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the TLS202B1MBV33HTMA1 and TLS202B1MBV33HTSA1 carry automotive grade classification and AEC-Q100 qualification, meeting automotive industry reliability and quality standards.

Q: Is the package footprint identical between these parts?

A: Yes. Both parts use the same 6-SMD (5 Leads) Gull Wing package with PG-SCT595-5-1 supplier device package designation. PCB layout and assembly processes require no modification.

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

A: Substitution is determined by matching output voltage (3.3V), output current (150mA), maximum input voltage (18V), dropout voltage (0.57V @ 150mA), quiescent current (75 µA), PSRR (63dB at 10kHz), operating temperature range (-40°C ~ 150°C), and protection features (over-current, over-temperature, short-circuit).
