Substitute Part Grouping Explanation

Substitution of the A1444EEWLT-P is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Motor type: Brushless DC (BLDC)
• Function: Fully integrated driver with control and power stage
• Output configuration: Half Bridge (2)
• Interface: On/Off control
• Technology: CMOS
• Package: 6-XFDFN Exposed Pad with 6-DFN/MLP (1.5x2) footprint
• Voltage supply range: 1.8V ~ 4.2V
• Voltage load range: 1.8V ~ 4.2V
• Operating temperature: -40°C ~ 165°C (TJ)
• Mounting type: Surface Mount

Allowable Variation:

• Output current capacity may differ within the same functional class, provided the substitute meets or exceeds application requirements

The A1448EEWLT-P qualifies as a parametric equivalent based on matching all critical parameters listed above.

Engineering Selection Recommendations

Both the A1444EEWLT-P and A1448EEWLT-P are classified as obsolete products. Selection between these parts should be based on the following criteria:

A1444EEWLT-P: Use when application requirements specify 250mA output current capacity. Current inventory status: 1141 pieces.

A1448EEWLT-P: Use when application requirements can operate within 200mA output current capacity. Current inventory status: 42095 pieces. This part offers significantly higher availability.

Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 classification) and thermal operating ranges. Package footprint and mounting requirements are identical, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can A1448EEWLT-P directly replace A1444EEWLT-P on existing PCBs?

A: Yes. Both parts use identical 6-XFDFN Exposed Pad packages with 6-DFN/MLP (1.5x2) footprints. No PCB layout modifications are required. The primary difference is output current capacity: A1448EEWLT-P provides 200mA versus 250mA for the A1444EEWLT-P.

Q: What is the key difference between these two parts?

A: Output current capacity. The A1444EEWLT-P delivers 250mA, while the A1448EEWLT-P delivers 200mA. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for haptic feedback applications?

A: Yes. Both parts are specified for haptic feedback applications with brushless DC motor control. Selection depends on whether your application requires the full 250mA output current or can operate within 200mA limits.

Q: What is the significance of the obsolete product status?

A: Both parts are classified as obsolete by the manufacturer. This indicates no new production is planned. Existing inventory from authorized distributors represents the available supply. The A1448EEWLT-P currently has substantially higher inventory availability (42095 pieces versus 1141 pieces).

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. Moisture sensitivity level (MSL 1 - Unlimited) is identical for both.

Q: What supply voltage range do these parts support?

A: Both parts operate across 1.8V to 4.2V for supply voltage and load voltage. This range is suitable for single-cell lithium-ion battery applications and regulated 3.3V systems.
