NJM2624AD Motor Driver IC - Equivalent & Substitute Parts

Part Overview

The NJM2624AD is a Brushless DC (BLDC) motor driver integrated circuit manufactured by Nisshinbo Micro Devices Inc. It functions as a commutation and direction management controller for three half-bridge pre-driver configurations, operating across a 4.5V to 18V supply voltage range. The device is packaged in a 16-DIP through-hole format and is rated for operating temperatures from -25°C to 85°C.

The NJM2624AD is classified as an obsolete product. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design updates require components with improved compliance status or extended availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NJM2624AD is determined by strict equivalence across the following critical parameters:

• Motor Control Function: Brushless DC (BLDC) commutation and direction management capability
• Output Architecture: Three half-bridge pre-driver configuration
• Interface Type: Parallel control interface
• Supply Voltage Range: 4.5V to 18V operation
• Operating Temperature Range: -25°C to 85°C
• Package Format: 16-DIP through-hole mounting with 0.300" (7.62mm) pitch
• Technology Platform: Bipolar semiconductor technology

The substitute part NJM2624AD# maintains identical electrical and mechanical specifications to the main part number, with differences limited to product status, packaging format, and compliance certifications.

Engineering Selection Recommendations

NJM2624AD# as Direct Substitute

The NJM2624AD# is a direct functional equivalent to the NJM2624AD. Both devices share identical electrical specifications, motor control capabilities, and physical package dimensions. Selection between these two part numbers is determined by non-functional factors:

• Product Status: The NJM2624AD# carries Active product status, ensuring continued manufacturer support and availability. The original NJM2624AD is Obsolete.
• RoHS Compliance: The NJM2624AD# is RoHS Compliant, meeting environmental and regulatory requirements for new designs. The NJM2624AD is RoHS non-compliant.
• Moisture Sensitivity: The NJM2624AD# has MSL 1 (Unlimited shelf life), compared to MSL 2 (1 Year) for the original part, reducing storage and handling constraints.
• REACH Status: The NJM2624AD# is REACH Unaffected, providing regulatory clarity for European market applications.
• Packaging: The NJM2624AD# is supplied in Tube packaging, suitable for automated assembly processes.

For new designs or production restarts, the NJM2624AD# is the appropriate selection. For legacy system repairs requiring exact original specifications, the NJM2624AD remains functionally identical.

Frequently Asked Questions (FAQ)

Q: Are NJM2624AD and NJM2624AD# electrically interchangeable?

A: Yes. Both devices provide identical electrical performance for Brushless DC motor commutation and direction control across the 4.5V to 18V supply range. Pin configuration, output drive capability, and control interface are identical.

Q: Can NJM2624AD# be used as a direct replacement in existing NJM2624AD designs?

A: Yes. The NJM2624AD# maintains pin-for-pin compatibility and identical electrical specifications. No circuit modifications are required for substitution.

Q: What is the significance of the RoHS compliance difference?

A: RoHS Compliance (NJM2624AD#) indicates the device meets Restriction of Hazardous Substances directives, restricting lead and other hazardous materials. This is required for products sold into European markets and many regulated industries. The non-compliant NJM2624AD may contain restricted substances.

Q: Why does the NJM2624AD# have a lower Moisture Sensitivity Level (MSL 1 vs MSL 2)?

A: MSL 1 (Unlimited) indicates the device has superior moisture resistance and does not require time-limited storage conditions. MSL 2 (1 Year) requires the original NJM2624AD to be used within one year of manufacture. The NJM2624AD# offers extended shelf life and reduced handling constraints.

Q: Are there any application limitations when substituting NJM2624AD with NJM2624AD#?

A: No. Both devices are rated for identical operating temperature ranges (-25°C to 85°C) and support the same motor control applications. Substitution is unrestricted from an application perspective.

Q: What is the difference between standard and Tube packaging?

A: Tube packaging (NJM2624AD#) is optimized for automated pick-and-place assembly equipment. Standard packaging (NJM2624AD) is suitable for manual or legacy assembly processes. Both contain identical components.

Q: Can NJM2624AD be used in new product designs?

A: The NJM2624AD is classified as Obsolete. While functional equivalence exists, new designs should specify NJM2624AD# to ensure long-term availability, compliance certifications, and manufacturer support.
