AP1347SL-13 Equivalent & Substitute Parts

Part Overview

The AP1347SL-13 is a motor driver IC manufactured by Diodes Incorporated, designed for brushless DC (BLDC) motor control applications with supply voltage range of 4V to 28V. This component functions as a commutation and direction management controller with pre-driver low-side output configuration, commonly used in fan controller applications. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP1347SL-13 is determined by the following critical parameters:

• Voltage supply range compatibility: 4V ~ 28V
• Package form factor: 8-SOIC (0.154", 3.90mm Width)
• Surface mount technology
• Motor control function with commutation and direction management capability
• Pre-driver low-side output configuration (2 channels)
• Operating temperature range requirements
• RoHS3 compliance and regulatory status

The TMP821DR from Texas Instruments meets these core substitution criteria. Both parts share identical supply voltage specifications, package geometry, mounting technology, and regulatory compliance status. The primary distinction lies in motor type support (BLDC versus brushed DC) and interface methodology (On/Off versus Parallel), which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TMP821DR is the manufacturer-recommended substitute for the obsolete AP1347SL-13. Both components maintain identical supply voltage specifications (4V ~ 28V) and package geometry (8-SOIC), ensuring direct PCB compatibility without layout modifications.

The TMP821DR offers extended operating temperature range (-40°C ~ 100°C versus -30°C ~ 85°C), providing broader environmental tolerance. The substitute part maintains active product status with established supply chain availability, addressing the obsolescence constraint of the original component.

Both parts achieve ROHS3 compliance and maintain equivalent regulatory status (EAR99, REACH Unaffected). The TMP821DR demonstrates superior moisture handling characteristics (MSL 1 versus MSL 3), reducing storage and handling constraints.

Application compatibility requires verification of motor type requirements (brushed DC for TMP821DR versus brushless DC for AP1347SL-13) and interface protocol alignment (Parallel control for TMP821DR versus On/Off control for AP1347SL-13).

Frequently Asked Questions (FAQ)

Q: Can the TMP821DR directly replace the AP1347SL-13 without PCB modifications?

A: Yes. Both components use identical 8-SOIC package geometry (0.154", 3.90mm Width) and surface mount technology, enabling direct pin-compatible substitution without PCB layout changes.

Q: What are the key differences between these two parts?

A: The primary differences are motor type support (brushed DC for TMP821DR versus brushless DC for AP1347SL-13), control interface methodology (Parallel versus On/Off), and operating temperature range (-40°C ~ 100°C for TMP821DR versus -30°C ~ 85°C for AP1347SL-13).

Q: Is the TMP821DR suitable for BLDC motor applications?

A: The TMP821DR is specified for brushed DC motor control. Applications requiring brushless DC motor commutation must evaluate whether the Parallel interface and brushed DC controller architecture meet functional requirements.

Q: What is the significance of the MSL rating difference?

A: The TMP821DR carries MSL 1 (Unlimited moisture exposure), while the AP1347SL-13 carries MSL 3 (168-hour limit). This indicates the substitute part has superior moisture resistance and reduced storage/handling constraints.

Q: Are both parts RoHS compliant?

A: Yes. Both the AP1347SL-13 and TMP821DR are ROHS3 compliant and maintain equivalent regulatory status under EAR99 and REACH Unaffected classifications.

Q: Why is the AP1347SL-13 classified as obsolete?

A: The AP1347SL-13 is listed as obsolete by the manufacturer. The TMP821DR, maintained in active product status by Texas Instruments, provides long-term design support and supply chain continuity.
