Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LT8636EV#PBF are identified based on strict electrical and mechanical parameter matching within the LT8636 product family. The substitution logic is determined by the following critical parameters:

• Input voltage range: 3.4V to 42V (identical across all variants)
• Output voltage range: 0.97V to 42V (identical across all variants)
• Output current: 5A (identical across all variants)
• Switching frequency: 200kHz to 3MHz (identical across all variants)
• Package configuration: 20-TFQFN Exposed Pad (identical across all variants)
• Synchronous rectifier: Yes (identical across all variants)
• RoHS and MSL compliance: Identical across all variants

The identified substitutes (LT8636HV#PBF and LT8636JV#PBF) maintain full electrical and mechanical compatibility with the LT8636EV#PBF. The primary distinction among these variants is the maximum operating temperature rating, which affects thermal performance specifications but does not alter core switching regulator functionality or pin configuration.

Parameter Comparison

Engineering Selection Recommendations

All three variants (LT8636EV#PBF, LT8636HV#PBF, and LT8636JV#PBF) maintain active product status with Analog Devices Inc. and carry identical ROHS3 compliance and MSL ratings. Selection between these parts is determined by thermal operating requirements:

The LT8636EV#PBF operates within a junction temperature range of -40°C to 125°C and is suitable for standard industrial and commercial applications with moderate thermal constraints.

The LT8636HV#PBF and LT8636JV#PBF extend the maximum junction temperature to 150°C, providing enhanced thermal performance for applications requiring sustained operation at elevated temperatures or in thermally demanding environments.

All variants share identical electrical specifications, pin configurations, and package dimensions, ensuring direct mechanical and electrical interchangeability within the specified thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can LT8636HV#PBF or LT8636JV#PBF be used as direct replacements for LT8636EV#PBF?

A: Yes. Both LT8636HV#PBF and LT8636JV#PBF are direct electrical and mechanical substitutes for LT8636EV#PBF. All three parts share identical input/output voltage ranges, output current ratings, switching frequency, package configuration, and pin assignments. The primary difference is the maximum operating junction temperature: LT8636EV#PBF is rated to 125°C, while LT8636HV#PBF and LT8636JV#PBF are rated to 150°C.

Q: What is the difference between LT8636HV#PBF and LT8636JV#PBF?

A: Both LT8636HV#PBF and LT8636JV#PBF share identical electrical and thermal specifications, with maximum junction temperature of 150°C. The variants are distinguished by internal grade or manufacturing process designations within the Analog Devices product line. From an engineering substitution perspective, they are functionally equivalent.

Q: Are there any package or pinout differences between these variants?

A: No. All three variants use the 20-TFQFN Exposed Pad package with 20-LQFN (4x3) supplier device package configuration. Pin assignments and mechanical dimensions are identical across all variants.

Q: What compliance certifications apply to all variants?

A: All three parts are ROHS3 compliant and carry MSL rating 3 (168 Hours). Both certifications are identical across LT8636EV#PBF, LT8636HV#PBF, and LT8636JV#PBF.

Q: Should I select a higher temperature-rated variant if my application operates below 125°C?

A: Selection should be based on actual thermal operating requirements. If your application operates within the -40°C to 125°C range, LT8636EV#PBF meets the specification. Higher temperature-rated variants (LT8636HV#PBF or LT8636JV#PBF) are selected when sustained operation above 125°C junction temperature is required or when thermal margin is a design consideration.
