Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-3APB303V is determined by matching the following core parameters: resistance value (30 kOhms), package type (0603), power rating (0.1W), composition (thin film), and automotive qualification (AEC-Q200). Parts are grouped into two categories based on provided specifications:

Upgrade Substitutes maintain or improve upon the original specifications while preserving all critical electrical and mechanical compatibility. These parts feature either improved temperature coefficient performance or tighter tolerance ratings.

Similar Substitutes maintain identical resistance, tolerance, and package specifications but differ in temperature coefficient characteristics. These parts remain fully compatible for applications where temperature coefficient variance is acceptable within design margins.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection between ERA-3APB303V and its equivalents depends on specific application requirements:

ERA-3ARB303V provides improved temperature coefficient performance (±10ppm/°C versus ±15ppm/°C) while maintaining identical tolerance and power specifications. This part is suitable for applications requiring enhanced thermal stability.

ERA-3ARW303V offers the tightest tolerance specification (±0.05%) combined with improved temperature coefficient (±10ppm/°C). This part addresses applications demanding superior accuracy and thermal performance.

ERA-3AEB303V maintains the original tolerance specification (±0.1%) but features a wider temperature coefficient (±25ppm/°C). This part is suitable for cost-optimized designs where thermal coefficient variance is within acceptable design margins. Highest inventory availability supports supply chain continuity.

All parts are AEC-Q200 qualified, REACH unaffected, and packaged in identical 0603 form factor with matching footprint and termination specifications.

Frequently Asked Questions (FAQ)

Q: Can ERA-3ARB303V directly replace ERA-3APB303V in existing designs?

A: Yes. ERA-3ARB303V maintains identical resistance, tolerance, power rating, and package specifications. The improved temperature coefficient (±10ppm/°C) represents a performance enhancement with no compatibility concerns.

Q: What is the primary difference between ERA-3ARW303V and ERA-3APB303V?

A: ERA-3ARW303V features tighter tolerance (±0.05% versus ±0.1%) and improved temperature coefficient (±10ppm/°C versus ±15ppm/°C). Both maintain identical resistance and power rating in the same 0603 package.

Q: Is ERA-3AEB303V suitable for high-precision applications?

A: ERA-3AEB303V maintains ±0.1% tolerance matching the original part but features a wider temperature coefficient (±25ppm/°C). Selection depends on whether the application can accommodate this temperature coefficient variance within design specifications.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed parts carry AEC-Q200 automotive qualification and operate across the identical -55°C to 155°C temperature range.

Q: Do substitute parts require PCB layout modifications?

A: No. All parts use the 0603 (1608 Metric) package with identical footprint, dimensions (0.063" L x 0.031" W), and termination configuration (2 terminations).

Q: Which part offers the best supply availability?

A: ERA-3AEB303V provides the highest inventory level (50972 units) for applications where supply chain continuity is a priority.
