ERA-8ARB7682V Equivalent & Substitute Parts

Part Overview

The ERA-8ARB7682V is a 76.8 kOhms ±0.1% thin film chip resistor in 1206 (3216 Metric) package rated for 0.25W power dissipation. This component is manufactured by Panasonic Electronic Components and meets AEC-Q200 automotive qualification standards. The part is actively produced and maintained in inventory, with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when design requirements permit tolerance upgrades or when primary inventory availability requires alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-8ARB7682V is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 76.8 kOhms (exact match required)
• Package type: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
• Automotive rating: AEC-Q200 (exact match required)

Allowable Variation Parameters:

• Tolerance: May be tighter (lower value) than ±0.1% without affecting compatibility
• Manufacturer: Alternative qualified manufacturers acceptable if all other parameters match

The ERA-8ARW7682V qualifies as a direct substitute because it maintains all mandatory parameters while offering improved tolerance specification (±0.05% versus ±0.1%).

Parameter Comparison

Engineering Selection Recommendations

Both ERA-8ARB7682V and ERA-8ARW7682V are active production components from Panasonic Electronic Components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on tolerance requirements:

• ERA-8ARB7682V: Select when circuit design specifies ±0.1% tolerance or when this tolerance is acceptable for the application.
• ERA-8ARW7682V: Select when circuit design requires ±0.05% tolerance or tighter tolerance specification. This part provides improved accuracy with identical electrical and mechanical characteristics.

Both components are suitable for automotive applications operating across the -55°C to 155°C temperature range. Packaging, footprint, and thermal characteristics are identical, permitting direct PCB layout compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARW7682V replace ERA-8ARB7682V in existing designs?

A: Yes. The ERA-8ARW7682V is a direct substitute with tighter tolerance specification (±0.05% versus ±0.1%). All electrical, mechanical, and thermal parameters are identical. No circuit redesign or PCB layout modification is required.

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

A: The tolerance specification differs. ERA-8ARB7682V provides ±0.1% tolerance, while ERA-8ARW7682V provides ±0.05% tolerance. Both maintain the same 76.8 kOhms resistance value and identical package dimensions.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both ERA-8ARB7682V and ERA-8ARW7682V carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use identical 1206 (3216 Metric) packaging with matching footprint dimensions (0.126" L x 0.063" W, 3.20mm x 1.60mm). No PCB layout changes are necessary for substitution.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-8ARB7682V and ERA-8ARW7682V are ROHS3 compliant.
