AM4967GSTR-G1 Equivalent & Substitute Parts

Part Overview

The AM4967GSTR-G1 is a Brushless DC (BLDC) motor driver IC manufactured by Diodes Incorporated, designed for general-purpose motor control applications. Operating across a supply voltage range of 5.5V to 16V, this device functions as a commutation and direction management controller with a pre-driver half-bridge output configuration. The part is currently in active production status with robust inventory availability (17,732 units in stock), making it suitable for immediate deployment in motor control systems requiring PWM-based commutation control.

Equivalent substitute parts are necessary to address supply chain continuity, regional availability constraints, or inventory optimization while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM4967GSTR-G1 is determined by strict equivalence across the following critical parameters:

• Motor Control Function: Brushless DC (BLDC) commutation and direction management controller
• Output Architecture: Pre-driver half-bridge configuration (2 channels)
• Control Interface: PWM-based commutation control
• Supply Voltage Range: 5.5V to 16V operation
• Thermal Operating Range: -30°C to 105°C (TA)
• Package Specification: 16-SSOP surface mount package (0.154" width, 3.90mm)
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The AM4967RGSTR-G1 meets all these criteria and is classified as a parametric equivalent. Both parts share identical base product designation (AM4967) and are manufactured by the same supplier, ensuring functional and mechanical interchangeability within the specified electrical operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the AM4967GSTR-G1 and AM4967RGSTR-G1 are active production parts manufactured by Diodes Incorporated with full ROHS3 compliance and MSL Level 1 rating. Selection between these parts should be based on supply chain availability and inventory status rather than electrical or mechanical performance differences, as all specified parameters are identical.

The AM4967RGSTR-G1 currently maintains higher inventory levels (19,663 units versus 17,732 units), which may provide supply chain advantages for high-volume production requirements. Both parts are suitable for immediate integration into motor control designs without circuit modification or thermal management redesign.

Frequently Asked Questions (FAQ)

Q: Are the AM4967GSTR-G1 and AM4967RGSTR-G1 pin-for-pin compatible?

A: Yes. Both parts use the identical 16-SSOP package with matching pin assignments, enabling direct PCB-level substitution without layout modification.

Q: Can these parts be used interchangeably in production?

A: Yes. The parts are parametric equivalents with identical electrical specifications, supply voltage range, operating temperature range, and functional characteristics. They are suitable for interchangeable use within the same design.

Q: What is the significance of the different suffix designations (GSTR vs. RGSTR)?

A: The suffix designations indicate different manufacturing date codes or tape reel configurations assigned by Diodes Incorporated. Both suffixes represent the same functional device with identical electrical and mechanical specifications.

Q: Are both parts compliant with current environmental and trade regulations?

A: Yes. Both the AM4967GSTR-G1 and AM4967RGSTR-G1 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: What is the MSL rating, and why is it relevant?

A: Both parts carry MSL Level 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements. This simplifies inventory management and reduces handling constraints during storage and assembly.

Q: Can these parts operate across the full -30°C to 105°C temperature range in all applications?

A: The specified operating temperature range is -30°C to 105°C (TA). Application-specific thermal analysis is required to confirm that junction temperatures remain within device specifications under maximum power dissipation conditions.
