Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-8ARB3482V is determined by the following critical parameters:

Resistance value must remain 34.8 kOhms. Package configuration must be 1206 (3216 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts. Composition must be thin film to maintain temperature stability and precision characteristics. Automotive AEC-Q200 qualification must be maintained for applications requiring automotive-grade reliability. Operating temperature range must support -55°C ~ 155°C minimum. RoHS3 compliance and MSL 1 rating must be preserved.

The ERA-8ARW3482V qualifies as a substitute because it maintains all critical parameters while offering improved tolerance specification (±0.05% versus ±0.1%).

Parameter Comparison

Engineering Selection Recommendations

Both ERA-8ARB3482V and ERA-8ARW3482V are active production components manufactured by Panasonic Electronic Components with full AEC-Q200 automotive qualification and ROHS3 compliance. The ERA-8ARW3482V offers tighter tolerance specification at ±0.05% compared to the ±0.1% of the ERA-8ARB3482V, while maintaining identical electrical and mechanical characteristics across all other parameters. Selection between these parts depends on circuit tolerance requirements and application specifications.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARW3482V replace ERA-8ARB3482V in existing designs?

A: Yes. Both parts share identical resistance value (34.8 kOhms), package configuration (1206), power rating (0.25W), composition (thin film), temperature coefficient (±10ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). The ERA-8ARW3482V provides improved tolerance specification.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. ERA-8ARB3482V provides ±0.1% tolerance, while ERA-8ARW3482V provides ±0.05% tolerance. All other electrical and mechanical parameters remain identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both ERA-8ARB3482V and ERA-8ARW3482V carry AEC-Q200 automotive qualification and are compliant with ROHS3 and REACH requirements.

Q: Does package size differ between these parts?

A: No. Both parts use the 1206 (3216 Metric) package with identical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum seated height of 0.028" (0.70mm).

Q: What is the moisture sensitivity level for these resistors?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
