Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-1ARB3570C is determined by strict equivalence across the following critical parameters:

• Resistance value: 357 Ohms (exact match required)
• Tolerance: ±0.1% (precision specification)
• Power rating: 0.05W minimum
• Package: 0201 (0603 Metric) form factor
• Composition: Thin film construction
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance and MSL 1 rating

The ERA-1AEB3570C meets all substitution criteria. Both parts share identical resistance, tolerance, power rating, package dimensions, and operating temperature specifications. The primary distinction is product status: ERA-1ARB3570C is obsolete while ERA-1AEB3570C is active production.

Parameter Comparison

Engineering Selection Recommendations

The ERA-1AEB3570C is the appropriate substitute for ERA-1ARB3570C applications. Both components are ROHS3 compliant and carry MSL 1 rating, ensuring regulatory and environmental compatibility. The ERA-1AEB3570C maintains active production status, providing supply chain continuity and long-term availability.

The temperature coefficient difference (±10ppm/°C vs. ±25ppm/°C) reflects manufacturing process variations within the ERA-1A series. For applications requiring the tighter ±10ppm/°C specification, this parameter must be evaluated against circuit performance requirements. In standard precision resistor applications, both coefficients remain within acceptable tolerance bands across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERA-1AEB3570C directly replace ERA-1ARB3570C in existing designs?

A: Yes. Both components share identical resistance value, tolerance, power rating, package dimensions, and operating temperature range. PCB layout and footprint compatibility are guaranteed.

Q: What is the significance of the temperature coefficient difference?

A: The ERA-1ARB3570C specifies ±10ppm/°C while ERA-1AEB3570C specifies ±25ppm/°C. This represents the maximum resistance change per degree Celsius. For a 357 Ohm resistor across the -55°C to 155°C range (210°C span), the ERA-1ARB3570C exhibits maximum drift of approximately 0.75 Ohms, while ERA-1AEB3570C exhibits approximately 1.88 Ohms. Circuit design must confirm whether this difference impacts performance.

Q: Are packaging options different between these parts?

A: The ERA-1ARB3570C packaging is not specified in the provided data. The ERA-1AEB3570C is supplied in Tape & Reel (TR) format. Both use identical 0201 (0603 Metric) package configuration.

Q: What is the compliance status of both parts?

A: Both ERA-1ARB3570C and ERA-1AEB3570C are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both carry ECCN EAR99 classification and HTSUS code 8533.21.0030.

Q: Why is ERA-1ARB3570C marked obsolete?

A: Product obsolescence reflects manufacturing discontinuation by Panasonic Electronic Components. The ERA-1AEB3570C from the same ERA-1A series provides functional continuity for new and replacement applications.
