Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLS205B0LDVXUMA1 is determined by strict equivalence across the following critical parameters:

Output characteristics must remain identical: positive adjustable output configuration with 500mA current capacity, 1.22V minimum output, and 20V maximum output voltage.

Electrical performance specifications must match: 20V maximum input voltage, 0.45V maximum dropout voltage at 500mA, 60µA quiescent current, and 65dB PSRR at 120Hz.

Functional features must be preserved: Enable control capability and protection against over-current, over-temperature, and reverse polarity conditions.

Environmental and compliance requirements must be maintained: automotive-grade classification, AEC-Q100 qualification, ROHS3 compliance, and -40°C to 125°C operating temperature range.

The substitute part TLS205B0EJVXUMA1 meets all these criteria while differing only in packaging format and product status, making it a valid functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TLS205B0EJVXUMA1 is a direct functional substitute for the TLS205B0LDVXUMA1 based on identical electrical specifications and automotive compliance certifications. Both parts share the same base product number (TLS205), OPTIREG™ series designation, and AEC-Q100 qualification status.

The primary distinction is packaging format: the main part uses a 10-TFDFN package while the substitute employs an 8-SOIC package. This packaging difference requires PCB layout modification but does not affect electrical performance or functional capability.

The substitute part holds Active product status, ensuring continued availability and supply chain stability compared to the main part's Last Time Buy designation. This status transition makes the TLS205B0EJVXUMA1 the preferred selection for new designs and long-term production requirements.

Both parts maintain identical moisture sensitivity levels and compliance certifications, supporting seamless integration into automotive applications requiring AEC-Q100 qualification.

Frequently Asked Questions (FAQ)

Q: Can TLS205B0EJVXUMA1 replace TLS205B0LDVXUMA1 in existing designs?

A: Electrical and functional replacement is complete. PCB layout modification is required due to package format change from 10-TFDFN to 8-SOIC. Pin configuration and electrical characteristics remain equivalent.

Q: What is the primary reason for substitution?

A: The main part (TLS205B0LDVXUMA1) is designated Last Time Buy, indicating production discontinuation. The substitute (TLS205B0EJVXUMA1) maintains Active status, ensuring long-term supply availability.

Q: Are there compliance or certification differences?

A: No. Both parts carry identical automotive-grade classification, AEC-Q100 qualification, ROHS3 compliance, and REACH Unaffected status.

Q: How do the packages differ?

A: TLS205B0LDVXUMA1 uses 10-TFDFN (Thin Shrink Small Outline Flat No-Lead) packaging. TLS205B0EJVXUMA1 uses 8-SOIC (Small Outline Integrated Circuit) packaging. Both are surface-mount with exposed pads.

Q: Are electrical specifications identical?

A: Yes. Output current (500mA), input/output voltage ranges (20V max), dropout voltage (0.45V @ 500mA), quiescent current (60µA), PSRR (65dB @ 120Hz), and protection features are identical across both parts.

Q: What is the operating temperature range?

A: Both parts operate across -40°C to 125°C junction temperature, meeting automotive environmental requirements.

Q: Are there inventory considerations?

A: TLS205B0LDVXUMA1 has 5400 pieces in stock (Last Time Buy status). TLS205B0EJVXUMA1 has 1396 pieces available with Active product status, supporting ongoing procurement.
