LT8337EV#PBF Equivalent & Substitute Parts

Part Overview

The LT8337EV#PBF is an active Boost Switching Regulator IC manufactured by Analog Devices Inc., classified as a Power Management (PMIC) component. This device functions as a step-up converter with positive output configuration, delivering programmable output voltage from 1V to 26V at 5A output current. The regulator operates across a wide input voltage range of 2.7V to 28V and incorporates a synchronous rectifier for improved efficiency. The LT8337EV#PBF is part of the Silent Switcher®1 series and maintains Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different temperature grades or manufacturing variants within the same base product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LT8337EV#PBF is determined by strict equivalence across the following critical parameters:

Electrical Performance Parameters:

• Input voltage range: 2.7V to 28V
• Output voltage range: 1V to 26V
• Output current: 5A
• Switching frequency: 300kHz to 3MHz
• Synchronous rectifier functionality: Present

Mechanical & Package Parameters:

• Package type: 16-TFQFN Exposed Pad
• Mounting type: Surface Mount
• Supplier device package: 16-LQFN (3x3)

Regulatory & Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level: 3 (168 Hours)
• Base product family: LT8337

The LT8337JV#PBF qualifies as a direct substitute based on identical electrical specifications, package configuration, and regulatory compliance. The primary distinction between the main part and substitute relates to operating temperature range, which does not affect functional substitution in applications operating within the main part's specified temperature limits.

Parameter Comparison

Engineering Selection Recommendations

Both the LT8337EV#PBF and LT8337JV#PBF maintain Active product status from Analog Devices Inc., ensuring continued manufacturing support and availability. Both parts carry identical RoHS3 compliance certification and Moisture Sensitivity Level 3 rating, meeting equivalent regulatory and handling requirements.

The LT8337JV#PBF provides an extended operating temperature range of -40°C to 150°C compared to the main part's -40°C to 125°C specification. This extended temperature capability does not introduce incompatibility; rather, it provides additional thermal margin for applications operating within the main part's temperature envelope.

Selection between these parts should be based on application-specific requirements:

• Use LT8337EV#PBF when the standard -40°C to 125°C temperature range satisfies design requirements and inventory availability of the primary part is confirmed.
• Use LT8337JV#PBF when extended high-temperature operation to 150°C is required, or when the substitute part offers superior inventory availability.

Both parts are pin-compatible, functionally equivalent, and suitable for direct PCB-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can LT8337JV#PBF be used as a direct replacement for LT8337EV#PBF on existing PCBs?

A: Yes. Both parts share identical pinout, package configuration (16-TFQFN Exposed Pad), and electrical specifications across all critical parameters including input/output voltage ranges, output current, and switching frequency. No PCB redesign is required.

Q: What is the significance of the temperature range difference between these parts?

A: The LT8337JV#PBF operates to 150°C junction temperature versus 125°C for the LT8337EV#PBF.
