Substitute Part Grouping Explanation

Substitution eligibility for the ERA-8ARB3401V is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3.4 kOhms (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Composition: Thin Film (required for performance consistency)
• Automotive rating: AEC-Q200 (required for automotive applications)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)
• RoHS compliance: ROHS3 Compliant (required)

Flexible Parameters:

• Tolerance: Tighter tolerance (lower value) is acceptable as an upgrade
• Temperature coefficient: Equal or better performance acceptable

The ERA-8ARW3401V qualifies as a substitute because it maintains all mandatory parameters while offering improved tolerance specification (±0.05% versus ±0.1%), making it suitable for applications requiring higher precision.

Parameter Comparison

Engineering Selection Recommendations

Both ERA-8ARB3401V and ERA-8ARW3401V are active production components from Panasonic Electronic Components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on application tolerance requirements:

The ERA-8ARB3401V (±0.1% tolerance) is suitable for standard precision applications where the specified tolerance meets circuit performance requirements.

The ERA-8ARW3401V (±0.05% tolerance) provides tighter tolerance specification and is appropriate for applications requiring enhanced precision. This part is available in higher inventory quantity (4260 units versus 1757 units), which may support supply chain continuity.

Both parts share identical package dimensions, power rating, temperature coefficient, and operating temperature range, ensuring direct mechanical and thermal compatibility in circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARW3401V replace ERA-8ARB3401V in existing designs?

A: Yes. The ERA-8ARW3401V is a direct substitute with identical resistance value, package, power rating, and operating temperature range. The tighter tolerance (±0.05% versus ±0.1%) represents an upgrade in precision performance.

Q: Are there any package or footprint differences 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). PCB footprints are interchangeable.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERA-8ARB3401V and ERA-8ARW3401V carry AEC-Q200 automotive qualification and are suitable for automotive applications within the specified operating temperature range of -55°C ~ 155°C.

Q: What is the difference in tolerance between these parts?

A: ERA-8ARB3401V has ±0.1% tolerance, while ERA-8ARW3401V has ±0.05% tolerance. The ERA-8ARW3401V provides twice the tolerance precision, making it suitable for circuits requiring tighter resistance value control.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-8ARB3401V and ERA-8ARW3401V are ROHS3 compliant with moisture sensitivity level 1 (unlimited), meeting environmental and regulatory requirements.
