KMA220J Equivalent & Substitute Parts

Part Overview

The KMA220J is a magnetoresistive angle sensor manufactured by NXP USA Inc., designed to measure rotation angles from 0° to 180° using an external magnet actuator. The sensor outputs analog voltage signals with ±1.2° linearity and operates across a supply voltage range of 4.5V to 5.5V. The KMA220J is currently classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Parameter Comparison

Engineering Selection Recommendations

The KMA320/A is the direct substitute for the KMA220J based on electrical and mechanical parameter equivalence. Selection of the KMA320/A provides the following advantages:

• Active Product Status: The KMA320/A maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete KMA220J.
• Extended Operating Temperature Range: The KMA320/A supports -40°C to 180°C operation, providing 20°C additional high-temperature capability over the KMA220J's -40°C to 160°C range.
• Automotive Grade Qualification: The KMA320/A carries AEC-Q100 qualification, meeting automotive industry reliability standards.
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Pin-to-pin compatibility, identical package configuration, and matching electrical specifications enable direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the KMA320/A directly replace the KMA220J in existing designs?

A: Yes. The KMA320/A provides pin-to-pin compatibility with identical 4-SIP module packaging, matching supply voltage range (4.5V ~ 5.5V), and equivalent analog voltage output characteristics. No circuit modifications are required.

Q: What are the key differences between KMA220J and KMA320/A?

A: The primary differences are product status (obsolete versus active), operating temperature range (160°C versus 180°C maximum), and automotive qualification (standard versus AEC-Q100). All core sensing parameters remain identical.

Q: Are there any compatibility concerns with the external magnet actuator?

A: No. Both components require external magnet actuators and are not included with the sensors. Existing magnet configurations used with the KMA220J are compatible with the KMA320/A.

Q: Does the KMA320/A require different PCB layout or mounting considerations?

A: No. The KMA320/A uses identical through-hole PC pin termination and 4-SIP module package dimensions. Existing PCB designs require no modification.

Q: What is the significance of AEC-Q100 qualification on the KMA320/A?

A: AEC-Q100 qualification indicates the component meets automotive industry reliability and quality standards. This certification is relevant for automotive applications but does not affect functionality in non-automotive environments.
