AM4961GHTR-E1 Equivalent & Substitute Parts

Part Overview

The AM4961GHTR-E1 is a Brushless DC (BLDC) motor driver IC manufactured by Diodes Incorporated, designed for fully integrated motor control and power stage applications. This component operates as a half-bridge PWM driver with bipolar technology, supporting output currents up to 1A and supply voltages from 4.6V to 16V. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM4961GHTR-E1 is determined by strict equivalence across the following critical parameters:

• Motor Type: Brushless DC (BLDC)
• Function: Driver - Fully Integrated, Control and Power Stage
• Output Configuration: Half Bridge (2)
• Interface: PWM
• Technology: Bipolar
• Current - Output: 1A
• Voltage - Supply: 4.6V ~ 16V
• Voltage - Load: 4.6V ~ 16V
• Operating Temperature: -30°C ~ 90°C (TA)
• Package / Case: 14-TSSOP (0.173", 4.40mm Width) + 2 Heat Tabs
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain these electrical and mechanical specifications. The primary distinction between the main part and substitutes is product status: the AM4961GHTR-E1 is obsolete, while the substitute parts are active and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—AM4961AGHTR-G1, AM4961GHTR-G1, and AM4962GHTR-G1—are electrically and mechanically equivalent to the AM4961GHTR-E1 and maintain full ROHS3 compliance. The primary selection criteria are product availability and procurement status:

AM4961GHTR-G1 is the recommended primary substitute, offering the highest inventory availability (28,400 units) with active product status and standard Tape & Reel packaging suitable for production environments.

AM4962GHTR-G1 provides the largest inventory reserve (136,200 units) and represents an alternative within the same functional family, maintaining all critical electrical parameters.

AM4961AGHTR-G1 is available with lower inventory (995 units) and serves as a secondary option when primary substitutes are constrained.

All substitutes are suitable for direct replacement in applications currently using the obsolete AM4961GHTR-E1, provided that moisture sensitivity level (MSL) handling requirements are observed during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can AM4961GHTR-G1 directly replace AM4961GHTR-E1 in existing designs?

A: Yes. Both parts share identical electrical specifications, output configuration, voltage ratings, current capacity, operating temperature range, and package geometry. The primary difference is product status: AM4961GHTR-E1 is obsolete while AM4961GHTR-G1 is active. Packaging format differs (bulk versus Tape & Reel), but this does not affect functional compatibility.

Q: What is the difference between AM4961AGHTR-G1 and AM4961GHTR-G1?

A: Both parts are electrically equivalent with identical motor driver specifications. The designator suffix (-A-) in AM4961AGHTR-G1 indicates a variant within the AM4961 base product family. All critical parameters—voltage, current, temperature range, package, and interface—are identical. Selection between these parts should be based on inventory availability and procurement lead time.

Q: How does AM4962GHTR-G1 differ from the AM4961 variants?

A: AM4962GHTR-G1 maintains the same electrical specifications, output configuration, voltage ratings, current capacity, and package geometry as the AM4961 variants. The base product number change (AM4962 versus AM4961) indicates a product line variant. All three parts are functionally interchangeable for BLDC motor driver applications within the specified parameters.

Q: Are there any moisture sensitivity considerations when substituting these parts?

A: The AM4961GHTR-E1 has MSL 1 (unlimited shelf life), while all active substitutes have MSL 3 (168-hour limit at 30°C/60% RH). Designs using substitute parts must implement appropriate moisture control during storage and assembly to comply with MSL 3 requirements. This does not affect functional performance but requires adherence to standard moisture handling protocols.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that the selected substitute part meets procurement, inventory, and packaging requirements for your production environment. All parts maintain identical electrical and mechanical specifications. Tape & Reel packaging (used by all active substitutes) is standard for automated assembly processes.
