NJM2624AM Motor Driver IC - Equivalent & Substitute Parts

Part Overview

The NJM2624AM is a Brushless DC (BLDC) motor driver integrated circuit manufactured by Nisshinbo Micro Devices Inc. It functions as a commutation and direction management controller with three pre-driver half-bridge outputs, designed for general-purpose motor control applications across a 4.5V to 18V supply voltage range. The device is packaged in a 16-SOIC surface-mount configuration and operates across an industrial temperature range of -25°C to 85°C.

The NJM2624AM is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance of systems utilizing this motor driver architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NJM2624AM is determined by strict equivalence across the following critical parameters:

Motor Control Architecture: The substitute part must function as a Brushless DC (BLDC) motor controller with commutation and direction management capabilities.

Output Stage Configuration: The substitute must provide three pre-driver half-bridge outputs to maintain compatibility with existing motor drive topologies.

Interface Protocol: The substitute must support parallel interface communication to ensure direct compatibility with existing control circuitry.

Electrical Specifications: The substitute must operate within the 4.5V to 18V supply voltage range and maintain the -25°C to 85°C operating temperature specification.

Physical Package: The substitute must be housed in a 16-SOIC surface-mount package with identical pin configuration and mechanical dimensions (0.209" width, 5.30mm).

Technology Platform: The substitute must utilize bipolar semiconductor technology to ensure electrical characteristic compatibility.

Based on these criteria, the NJM2624AM# (Tube packaging variant) qualifies as a direct substitute part.

Parameter Comparison

Engineering Selection Recommendations

The NJM2624AM# represents a direct functional and electrical equivalent to the obsolete NJM2624AM. Both parts share identical motor control architecture, electrical specifications, and physical packaging.

Product Status Consideration: The NJM2624AM is classified as obsolete, while the NJM2624AM# maintains active product status. This distinction is significant for long-term supply chain planning and design continuity.

Compliance Advantages: The NJM2624AM# offers improved regulatory compliance compared to the main part. It achieves RoHS Compliant status, whereas the NJM2624AM is RoHS non-compliant. This compliance improvement is relevant for applications subject to environmental regulations.

Moisture Sensitivity: The NJM2624AM# demonstrates superior moisture handling characteristics with MSL 1 (Unlimited shelf life) compared to the NJM2624AM's MSL 2 (1 Year shelf life). This provides extended storage capability and reduced risk of moisture-induced failures during inventory management.

Packaging Format: The NJM2624AM# is supplied in Tube packaging, which may differ from the original part's packaging format. Verify that tube packaging is compatible with existing assembly and handling procedures.

Electrical Equivalence: All critical electrical parameters—supply voltage range, operating temperature, output configuration, and interface protocol—are identical between the two parts, confirming direct substitution capability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can the NJM2624AM# be used as a direct replacement for the NJM2624AM in existing designs?

A: Yes. The NJM2624AM# is electrically and functionally equivalent to the NJM2624AM. Both parts provide identical motor control functionality, operate across the same 4.5V to 18V supply voltage range, and are housed in the same 16-SOIC package. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference between the two parts?

A: The NJM2624AM is classified as obsolete, indicating that Nisshinbo Micro Devices Inc. no longer manufactures or supports this part. The NJM2624AM# maintains active product status, ensuring ongoing availability, technical support, and compliance with current manufacturing standards. For new designs or long-term production, the NJM2624AM# is the recommended choice.

Q: Does the RoHS compliance difference affect substitution?

A: The NJM2624AM# is RoHS Compliant, while the NJM2624AM is RoHS non-compliant. If your application or market requires RoHS compliance, the NJM2624AM# satisfies this requirement. If RoHS compliance is not a requirement, both parts are functionally equivalent. Verify your application's regulatory requirements before selection.

Q: What does the MSL rating difference mean for handling and storage?

A: MSL (Moisture Sensitivity Level) indicates the maximum shelf life under controlled storage conditions. The NJM2624AM# has MSL 1 (Unlimited shelf life), while the NJM2624AM has MSL 2 (1 Year shelf life). The NJM2624AM# provides extended storage capability and reduced risk of moisture-induced failures. If the NJM2624AM has been in inventory for extended periods, verify its moisture exposure history before use.

Q: Are there any package or pinout differences between the two parts?

A: No. Both the NJM2624AM and NJM2624AM# are housed in a 16-SOIC package with identical dimensions (0.209" width, 5.30mm) and pinout configuration. The only packaging difference is the format: the NJM2624AM# is supplied in Tube packaging. Verify that tube packaging is compatible with your assembly equipment and handling procedures.

Q: What is the base product number, and how does it relate to these part variants?

A: The base product number is NJM2624. Both the NJM2624AM and NJM2624AM# are variants of this base product, differentiated by packaging format and compliance status. The base product number is useful for identifying related parts and accessing technical documentation.

Q: Can I mix NJM2624AM and NJM2624AM# parts in the same production batch?

A: Yes. Since both parts are electrically and functionally equivalent with identical pinout and package dimensions, they can be used interchangeably in the same circuit. However, document the part number used in each unit for traceability and compliance purposes.
