Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-8ARB5232V is determined by the following critical parameters:

• Resistance value: Must be 52.3 kOhms
• Package type: Must be 1206 (3216 Metric)
• Power rating: Must be 0.25W minimum
• Composition: Must be thin film
• Temperature coefficient: Must be ±10ppm/°C or better
• Operating temperature range: Must cover -55°C to 155°C
• Automotive compliance: Must maintain AEC-Q200 rating
• RoHS compliance: Must be ROHS3 compliant

The ERA-8ARW5232V qualifies as a direct substitute based on these parameters. The tolerance specification differs (±0.05% versus ±0.1%), representing an upgrade in precision while maintaining all other electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both ERA-8ARB5232V and ERA-8ARW5232V are active products with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on tolerance requirements:

• ERA-8ARB5232V: Use when ±0.1% tolerance meets circuit specifications
• ERA-8ARW5232V: Use when ±0.05% tolerance is required for improved precision

Both parts share identical package dimensions, power rating, temperature coefficient, and operating temperature range. Substitution is electrically and mechanically valid for applications where the tolerance upgrade does not create cost or supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARW5232V replace ERA-8ARB5232V in existing designs?
