Substitute Part Grouping Explanation

Substitute parts for the UA78L06ACLPRE3 are categorized based on strict electrical and mechanical compatibility criteria:

Parametric Equivalent (Direct Replacement): UA78L06ACLPR maintains identical electrical specifications including fixed 6.2V output, 100mA current capacity, 20V maximum input voltage, and TO-92-3 through-hole packaging. This part provides direct functional equivalence for applications requiring the same form factor and performance characteristics.

Functional Substitute (Enhanced Performance): TPS7A2401DBVR provides voltage regulation functionality with adjustable output configuration (1.24V to 17.75V range), higher output current capacity (200mA), improved dropout voltage (0.25V @ 200mA), and surface-mount SOT-23-5 packaging. This substitute accommodates designs requiring higher current delivery, lower dropout performance, or surface-mount assembly while maintaining positive output regulation and comprehensive protection features.

Substitution logic is based on the following allowed parameters: output configuration (positive), number of regulators (1), protection features (over current, over temperature), RoHS3 compliance, and functional voltage regulation capability within specified input/output ranges.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Existing Through-Hole Designs: UA78L06ACLPR is the parametric equivalent, offering identical electrical performance and TO-92-3 packaging. Both the main part and this equivalent are obsolete; however, both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for legacy system maintenance and repair applications.

For New Designs or Surface-Mount Assembly: TPS7A2401DBVR is recommended as a functional substitute. This part is active in production, providing long-term availability and supply chain stability. The adjustable output configuration allows design flexibility for 6.2V fixed operation through external resistor network configuration. Enhanced performance specifications including 200mA output current, 0.25V dropout voltage, and extended operating temperature range (-40°C ~ 125°C) support demanding applications. Surface-mount SOT-23-5 packaging aligns with modern PCB assembly processes. ROHS3 compliance and REACH unaffected status maintain regulatory requirements.

Selection between parametric equivalent and functional substitute depends on assembly process requirements (through-hole versus surface-mount), supply chain considerations (obsolete versus active status), and performance headroom needs (current capacity and dropout voltage).

Frequently Asked Questions (FAQ)

Q: Can UA78L06ACLPR directly replace UA78L06ACLPRE3 in existing applications?

A: Yes. UA78L06ACLPR is a parametric equivalent with identical electrical specifications (6.2V fixed output, 100mA current, 20V maximum input, 1.7V dropout voltage) and identical TO-92-3 through-hole packaging. Pin configuration and functional behavior are equivalent for direct board-level substitution.

Q: What are the key differences between UA78L06ACLPR and TPS7A2401DBVR?

A: UA78L06ACLPR maintains fixed 6.2V output in TO-92-3 through-hole package. TPS7A2401DBVR provides adjustable output (1.24V ~ 17.75V), higher current capacity (200mA versus 100mA), lower dropout voltage (0.25V @ 200mA versus 1.7V @ 40mA), and surface-mount SOT-23-5 packaging. TPS7A2401DBVR is active in production; both UA78L06 variants are obsolete.

Q: Can TPS7A2401DBVR be configured for 6.2V fixed output?

A: TPS7A2401DBVR is adjustable output type. Fixed 6.2V operation requires external resistor network configuration per device datasheet. This approach is suitable for new designs but requires circuit redesign from through-hole TO-92-3 implementation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. UA78L06ACLPRE3, UA78L06ACLPR, and TPS7A2401DBVR are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What mounting considerations apply when switching from UA78L06ACLPRE3 to TPS7A2401DBVR?

A: UA78L06ACLPRE3 uses through-hole TO-92-3 package requiring PCB holes and manual or wave soldering. TPS7A2401DBVR uses surface-mount SOT-23-5 package requiring reflow soldering and surface-mount assembly process. PCB layout redesign is necessary for this substitution.

Q: Which substitute part should be selected for new production designs?

A: TPS7A2401DBVR is recommended for new designs. Active production status ensures long-term availability and supply chain stability. Enhanced performance specifications and surface-mount packaging align with modern manufacturing processes. Adjustable output configuration provides design flexibility while maintaining positive output regulation and comprehensive protection features.
