Substitute Part Grouping Explanation

Substitution for the SP7600EN2-L is determined by the following critical parameters:

Topology: Step-Down (Buck) configuration with internal switch
Output current capability: Minimum 1A to 2A range
Supply voltage range: Overlap with 4.5V to 29V input specification
Dimming capability: PWM and/or analog dimming support
Package compatibility: Surface mount with exposed pad preferred
Operating temperature: -40°C minimum to 85°C or higher maximum
Product status: Active preferred for long-term availability

Substitute parts are grouped into two categories:

Category A - Direct Topology Match (Step-Down Buck): Parts maintaining identical step-down buck topology with comparable output current (1A to 2A) and supply voltage ranges. These include XRP7613IDBTR-F, A6217KLJTR-1-T, AL8860WT-7, AL8861Y-13, AP8802HSP-13, HV9967BMG-G, IS31LT3353-V1STLS2-TR, LM3402HVMR/NOPB, and LM3404MR/NOPB.

Category B - Alternative Topology (Step-Up Boost): AP5725WG-7 operates as a step-up (boost) converter and is included for reference in applications where input voltage is lower than required output voltage.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

XRP7613IDBTR-F and A6217KLJTR-1-T are the preferred primary substitutes. Both maintain step-down buck topology with active product status and RoHS compliance. XRP7613IDBTR-F is from the same manufacturer (MaxLinear) and operates at comparable frequency (1MHz). A6217KLJTR-1-T offers automotive-grade qualification (AEC-Q100) and extended temperature range matching the original (-40°C ~ 125°C), with higher supply voltage ceiling (48V).

Secondary Substitutes (Topology Match, Current Derating):

AL8861Y-13 and IS31LT3353-V1STLS2-TR provide 1.5A and 1A output current respectively, suitable for applications where the full 2A capability is not required. Both support analog and PWM dimming. AL8861Y-13 offers the widest supply voltage range (4.5V to 40V) matching the original minimum input. IS31LT3353-V1STLS2-TR maintains the full operating temperature range (-40°C ~ 125°C).

Alternative Packages:

AL8860WT-7 (SOT-23-5) and AP8802HSP-13 (8-SOIC-EP) provide step-down buck functionality in different package footprints. AP8802HSP-13 maintains 8-SOIC-EP package compatibility with extended supply voltage range (8V to 60V) and full temperature rating (-40°C ~ 125°C).

Not Recommended for Direct Substitution:

AP5725WG-7 operates as a step-up (boost) converter and is unsuitable for direct replacement in applications requiring step-down regulation. HV9967BMG-G and LM3402HVMR/NOPB deliver reduced output current (750mA and 500mA respectively) and are appropriate only for lower-power lighting applications.

All recommended substitutes carry RoHS3 compliance and REACH unaffected status, meeting modern environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can XRP7613IDBTR-F directly replace SP7600EN2-L in all applications?

A: XRP7613IDBTR-F is compatible for applications where output current does not exceed 1.2A. The supply voltage range (7V to 36V) overlaps with the original (4.5V to 29V), though the minimum input is higher at 7V. Operating temperature maximum is reduced to 85°C versus the original 125°C. Verify application current requirements and thermal constraints before substitution.

Q: What is the key difference between A6217KLJTR-1-T and other substitutes?

A: A6217KLJTR-1-T is qualified to automotive standard AEC-Q100 and maintains the full operating temperature range (-40°C ~ 125°C) of the original. It supports PWM dimming only (not analog). The supply voltage range extends to 48V, providing greater headroom than the original 29V maximum.

Q: Why is AP5725WG-7 listed if it cannot directly replace SP7600EN2-L?

A: AP5725WG-7 is included for reference in system designs where input voltage is lower than required output voltage. It operates as a step-up (boost) converter with 2.7V to 5.5V input range, fundamentally different from the step-down topology of SP7600EN2-L. It is not a substitute but an alternative topology for specific circuit requirements.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts carry RoHS3 compliance status. The original SP7600EN2-L does not specify RoHS status. Verify RoHS compliance requirements for your application and supply chain documentation.

Q: What package considerations apply when selecting a substitute?

A: The original SP7600EN2-L uses 8-HSOIC (8-SOIC with exposed pad). Direct package-compatible substitutes include XRP7613IDBTR-F (8-SOIC-EP), A6217KLJTR-1-T (8-SOIC-EP), and AP8802HSP-13 (8-SOIC-EP). AL8860WT-7 and IS31LT3353-V1STLS2-TR use SOT-23-5 packages, requiring PCB layout redesign. AL8861Y-13 uses SOT-89-5, and HV9967BMG-G uses 8-MSOP. Package selection impacts thermal performance and board space.

Q: Which substitute offers the widest supply voltage range?

A: AP8802HSP-13 supports 8V to 60V input, the widest range among substitutes. However, its minimum input (8V) exceeds the original (4.5V). For applications requiring low input voltage operation, AL8860WT-7 and AL8861Y-13 maintain the 4.5V minimum input specification.

Q: Can I use LM3404MR/NOPB as a substitute?

A: LM3404MR/NOPB is compatible for applications where 1A output current is sufficient. It supports PWM dimming only (not analog) and operates across 6V to 42V input range. The supply voltage minimum (6V) is higher than the original (4.5V). Full operating temperature range (-40°C ~ 125°C) matches the original specification.
