Substitute Part Grouping Explanation

Substitution of the ERA-8ARB2152V is permissible when the following critical parameters remain constant or improve:

• Resistance value: 21.5 kOhms (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Composition: Thin Film (maintains performance characteristics)
• Temperature coefficient: ±10ppm/°C or better
• Operating temperature range: -55°C to 155°C minimum
• Automotive rating: AEC-Q200 (required for automotive applications)
• RoHS compliance: ROHS3 or equivalent
• Moisture sensitivity: MSL 1 or better

The ERA-8ARW2152V qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±0.05% versus ±0.1%).

Parameter Comparison

Engineering Selection Recommendations

Both ERA-8ARB2152V and ERA-8ARW2152V are active production components manufactured by Panasonic Electronic Components with full AEC-Q200 automotive qualification. Selection between these parts depends on tolerance requirements for the application circuit.

The ERA-8ARB2152V with ±0.1% tolerance is suitable for general automotive applications where standard precision resistor performance is acceptable. The ERA-8ARW2152V with ±0.05% tolerance provides enhanced precision and is appropriate for circuits requiring tighter resistance value control. Both parts maintain identical mechanical compatibility, thermal characteristics, and compliance certifications. Component selection should be based on circuit tolerance stack-up analysis and application-specific precision requirements.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARW2152V replace ERA-8ARB2152V in existing designs?

A: Yes. The ERA-8ARW2152V is a direct mechanical and electrical substitute. It maintains identical package dimensions (1206), power rating (0.25W), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). The improved tolerance specification (±0.05% versus ±0.1%) does not create compatibility issues and may improve circuit performance.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use identical 1206 (3216 Metric) package specifications with matching dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum seated height of 0.028" (0.70mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERA-8ARB2152V and ERA-8ARW2152V carry AEC-Q200 automotive qualification and ROHS3 compliance. Both are suitable for automotive applications within the specified operating temperature range of -55°C to 155°C.

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

A: The primary difference is tolerance specification. ERA-8ARB2152V offers ±0.1% tolerance, while ERA-8ARW2152V offers ±0.05% tolerance. All other electrical and mechanical parameters remain identical. The tighter tolerance of ERA-8ARW2152V provides enhanced precision for applications requiring stricter resistance value control.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture handling or baking requirements during storage or assembly.
