MP8802DJ-2.5-LF-Z Equivalent & Substitute Parts

Part Overview

The MP8802DJ-2.5-LF-Z is a linear voltage regulator IC manufactured by Monolithic Power Systems, classified as a Power Management (PMIC) component. This positive adjustable (fixed) output regulator delivers 250mA maximum output current in a compact TSOT-23-5 surface mount package. The device is actively produced and widely stocked, with 23,100 units available in inventory.

Identifying equivalent and substitute parts becomes necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit functional alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP8802DJ-2.5-LF-Z is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use SOT-23-5 surface mount packaging to ensure PCB layout and assembly compatibility.

Output Configuration: The substitute must maintain positive output configuration.

Voltage Specifications: The substitute must support the required fixed output voltage of 2.5V and accommodate the input voltage range up to 6.5V.

Current Rating: The substitute must deliver sufficient output current for the application. The MP8802DJ-2.5-LF-Z provides 250mA; substitutes with lower current ratings (such as 150mA) are acceptable only when application current requirements do not exceed the substitute's maximum output current specification.

Operating Temperature Range: The substitute must support the full operating temperature range of -40°C to 125°C.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and equivalent MSL ratings for manufacturing and storage compatibility.

The LP3985IM5-2.5/NOPB from Texas Instruments qualifies as a manufacturer-recommended substitute based on these criteria, with the exception that its maximum output current is 150mA compared to the 250mA of the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both the MP8802DJ-2.5-LF-Z and LP3985IM5-2.5/NOPB maintain Active product status with full ROHS3 compliance and unlimited moisture sensitivity level ratings, ensuring equivalent manufacturing and long-term reliability profiles.

The primary distinction between these parts is the maximum output current specification: 250mA for the MP8802DJ-2.5-LF-Z versus 150mA for the LP3985IM5-2.5/NOPB. Selection between these parts must be based on the actual current requirements of the application circuit. If the application draws 150mA or less, the LP3985IM5-2.5/NOPB provides a direct functional substitute. If the application requires current between 150mA and 250mA, only the MP8802DJ-2.5-LF-Z is suitable.

Both parts operate across the identical temperature range (-40°C to 125°C) and share the same fixed output voltage of 2.5V. The LP3985IM5-2.5/NOPB exhibits superior dropout voltage performance (0.1V @ 150mA) compared to the MP8802DJ-2.5-LF-Z (0.19V @ 250mA), which may provide marginal efficiency benefits in current-limited applications.

Frequently Asked Questions (FAQ)

Q: Can the LP3985IM5-2.5/NOPB directly replace the MP8802DJ-2.5-LF-Z in all applications?

A: Direct replacement is possible only when the application circuit draws a maximum of 150mA. The LP3985IM5-2.5/NOPB has a lower current rating (150mA) than the MP8802DJ-2.5-LF-Z (250mA). If your circuit requires more than 150mA, the LP3985IM5-2.5/NOPB cannot be used.

Q: Are the package dimensions identical between these two parts?

A: Both parts use SOT-23-5 surface mount packaging. The MP8802DJ-2.5-LF-Z uses SOT-23-5 Thin (TSOT-23-5), while the LP3985IM5-2.5/NOPB uses SC-74A (SOT-23-5). These are mechanically compatible for PCB layout purposes, though the thin variant may have slightly different height specifications.

Q: Do both parts support the same input voltage range?

A: The MP8802DJ-2.5-LF-Z supports input voltages up to 6.5V, while the LP3985IM5-2.5/NOPB supports up to 6V. If your input voltage approaches or exceeds 6V, verify that the LP3985IM5-2.5/NOPB maximum rating is not exceeded.

Q: What is the difference in quiescent current between these regulators?

A: The MP8802DJ-2.5-LF-Z has a quiescent current of 155 µA, while the LP3985IM5-2.5/NOPB has 150 µA. This difference is negligible for most applications.

Q: Are both parts suitable for battery-powered applications?

A: Both parts maintain identical operating temperature ranges (-40°C to 125°C) and unlimited MSL ratings, making them suitable for battery-powered applications. The LP3985IM5-2.5/NOPB offers slightly lower dropout voltage, which may provide marginal power efficiency benefits in low-voltage battery systems.

Q: What compliance certifications apply to both parts?

A: Both the MP8802DJ-2.5-LF-Z and LP3985IM5-2.5/NOPB are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 for export purposes.
