Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A3980KLPTR is determined by strict parametric equivalence across the following critical criteria:

Motor control architecture and output configuration must remain identical: bipolar stepper motor driver with four half-bridge outputs and fully integrated control and power stage functionality.

Electrical specifications must match exactly: 3V to 5.5V supply voltage range, 7V to 50V load voltage range, 1A output current capability, and -40°C to 150°C operating temperature range.

Package and mounting specifications must be identical: 28-TSSOP surface mount package with exposed pad, maintaining 0.173" width (4.40mm) dimensions.

Technology platform must remain consistent: DMOS logic-based implementation with identical step resolution capabilities (1, 1/2, 1/8, 1/16).

Automotive qualification and AEC-Q100 compliance are mandatory for substitution in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The A3980KLPTR-T serves as the parametric equivalent substitute for the obsolete A3980KLPTR. Both devices maintain identical electrical and functional specifications, ensuring direct compatibility in motor driver applications requiring bipolar stepper control with integrated power stage functionality.

The A3980KLPTR-T carries AEC-Q100 automotive qualification and ROHS3 compliance status, providing improved regulatory alignment compared to the original part. The transition from MSL 1 to MSL 2 requires standard moisture control procedures during storage and handling, consistent with industry practices for surface mount components.

Both parts are available in the identical 28-TSSOP surface mount package with exposed pad configuration, permitting direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can A3980KLPTR-T be used as a direct replacement for A3980KLPTR?

A: Yes. Both parts are parametrically equivalent across all critical electrical, functional, and package specifications. The A3980KLPTR-T maintains identical motor driver architecture, output configuration, voltage ranges, current ratings, and operating temperature specifications. Direct substitution is supported without circuit modification.

Q: What is the difference in product status between these parts?

A: The A3980KLPTR is classified as Obsolete, indicating end-of-life status. The A3980KLPTR-T is classified as Not For New Designs, reflecting its transitional status. For new production designs, consult Allegro MicroSystems for current-generation alternatives.

Q: Are there packaging differences between the two parts?

A: No. Both parts use identical 28-TSSOP surface mount packaging with exposed pad configuration. PCB footprints, land patterns, and mounting procedures remain unchanged.

Q: What is the impact of the MSL rating change from 1 to 2?

A: MSL 1 indicates unlimited shelf life under controlled conditions. MSL 2 specifies a one-year moisture sensitivity window. Standard moisture control procedures during component storage and handling are required for the A3980KLPTR-T, consistent with industry practices for automotive-grade surface mount devices.

Q: Does the ROHS3 compliance of A3980KLPTR-T affect circuit performance?

A: No. ROHS3 compliance reflects material composition and environmental standards compliance. Electrical performance, functional behavior, and motor control characteristics remain identical to the original part.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the A3980KLPTR and A3980KLPTR-T carry Automotive grade classification and AEC-Q100 qualification, meeting automotive industry reliability and quality standards.
