• Temperature coefficient: ±10ppm/°C (identical)
• Operating temperature range: -55°C to 155°C (identical)
• Automotive rating: AEC-Q200 (identical)
• Physical dimensions: 0.126" L x 0.063" W, 0.028" max height (identical)
• Termination count: 2 (identical)
• RoHS and REACH compliance: ROHS3 Compliant, REACH Unaffected (identical)

Improved Parameter:

• Tolerance: ±0.05% (tighter than ±0.1% original specification)

The ERA-8ARW332V represents an upgrade path with enhanced tolerance specification while maintaining full compatibility across all mechanical, thermal, and regulatory parameters.

Parameter Comparison

Engineering Selection Recommendations

Both ERA-8ARB332V and ERA-8ARW332V are active production components from Panasonic Electronic Components with full AEC-Q200 automotive qualification and ROHS3 compliance. The ERA-8ARW332V provides tighter tolerance specification (±0.05% versus ±0.1%) while maintaining identical mechanical, thermal, and regulatory characteristics. Selection between these parts depends on circuit tolerance requirements: the ERA-8ARB332V is suitable for applications requiring ±0.1% tolerance, while the ERA-8ARW332V is appropriate for circuits demanding higher precision at ±0.05% tolerance. Both parts are suitable for automotive applications operating across the -55°C to 155°C temperature range with identical power dissipation capabilities in the 1206 package format.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARW332V replace ERA-8ARB332V in existing designs? A: Yes. The ERA-8ARW332V is mechanically and electrically compatible with ERA-8ARB332V. Both parts share identical package dimensions (1206), power rating (0.25W), resistance value (3.3 kOhms), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. The ERA-8ARW332V features improved tolerance specification (±0.05% versus ±0.1%).

Q: What is the primary difference between these two parts? A: The tolerance specification differs. ERA-8ARB332V has ±0.1% tolerance, while ERA-8ARW332V has ±0.05% tolerance. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for automotive applications? A: Yes. Both ERA-8ARB332V and ERA-8ARW332V carry AEC-Q200 automotive qualification and are rated for operating temperatures from -55°C to 155°C.

Q: Do these parts have the same package dimensions? A: Yes. Both parts use the 1206 (3216 Metric) package with identical physical dimensions: 0.126" L x 0.063" W and maximum seated height of 0.028".

Q: Are there any compliance differences between these parts? A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) rating.

Q: Which part should I select for high-precision applications? A: The ERA-8ARW332V with ±0.05% tolerance is appropriate for circuits requiring tighter tolerance control compared to the ERA-8ARB332V at ±0.1%.
