RG3216N-3572-B-T5 Equivalent & Substitute Parts

Part Overview

The RG3216N-3572-B-T5 is a 35.7 kOhms ±0.1% thin film chip resistor manufactured by Susumu in 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation and features anti-sulfur coating with automotive AEC-Q200 qualification. The part is actively produced and maintained in inventory. Substitute parts are identified to provide alternative sourcing options when the primary manufacturer part becomes unavailable or when supply chain optimization is required.

Substitute Part Grouping Explanation

Substitution eligibility for the RG3216N-3572-B-T5 is determined by strict equivalence across the following critical parameters:

Resistance value must equal 35.7 kOhms with tolerance of ±0.1%. Power rating must be 0.25W (1/4W) minimum. Package format must be 1206 (3216 Metric). Composition must be thin film. Temperature coefficient must be ±10ppm/°C. Operating temperature range must span -55°C to 155°C. Automotive AEC-Q200 rating is required. RoHS3 compliance and MSL 1 classification must be maintained.

The ERA-8ARB3572V manufactured by Panasonic Electronic Components meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RG3216N-3572-B-T5 and ERA-8ARB3572V are active production components with full AEC-Q200 automotive qualification. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical performance differences.

The RG3216N-3572-B-T5 features anti-sulfur coating, which provides enhanced environmental protection in corrosive atmospheres. The ERA-8ARB3572V does not specify anti-sulfur treatment. This distinction is relevant only for applications requiring explicit sulfur resistance.

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for automotive and industrial applications. The maximum seated height difference of 0.008" (0.20mm) between the two parts is negligible for standard PCB assembly processes and does not affect circuit performance or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARB3572V be used as a direct replacement for RG3216N-3572-B-T5?

A: Yes. Both parts share identical electrical specifications (35.7 kOhms ±0.1%, 0.25W, ±10ppm/°C), package format (1206), and automotive ratings (AEC-Q200). The seated height difference of 0.008" is within standard PCB assembly tolerances and does not affect functionality.

Q: What is the significance of the anti-sulfur feature on the RG3216N-3572-B-T5?

A: Anti-sulfur coating protects the resistor element from sulfur-containing environmental contaminants that can degrade thin film resistors. This feature is specified for the Susumu part but not for the Panasonic equivalent. Selection should account for application environment requirements.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RG3216N-3572-B-T5 and ERA-8ARB3572V carry AEC-Q200 automotive qualification and operate across the -55°C to 155°C temperature range required for automotive use.

Q: What is the difference in moisture sensitivity between these parts?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply to both components.

Q: Can these parts be used interchangeably in high-precision circuits?

A: Yes. Both parts meet ±0.1% tolerance and ±10ppm/°C temperature coefficient specifications, making them suitable for precision analog circuits, measurement instrumentation, and reference networks.

Q: Are there any PCB layout considerations when substituting these parts?

A: The maximum seated height difference of 0.008" (0.20mm) is negligible for standard reflow soldering and automated assembly. No PCB layout modifications are required when substituting between these parts.
