Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC3570P is determined by strict equivalence across the following critical parameters:

• Resistance value: 357 Ohms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power rating: 0.063W, 1/16W (electrical stress rating)
• Composition: Thin Film (performance characteristics)
• Package: 0402 (1005 Metric) (physical and thermal footprint)
• Temperature coefficient: ±25ppm/°C (frequency stability)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The ERA-2AEC3570X meets all these criteria and qualifies as a direct substitute. The primary distinction is the addition of AEC-Q200 automotive qualification and an extended upper operating temperature limit of 155°C versus 125°C for the original part.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC3570X is the qualified substitute for the obsolete ERA-2HEC3570P. Both components share identical electrical specifications (357 Ohms, ±0.25% tolerance, 0.063W power rating) and mechanical compatibility (0402 package). The ERA-2AEC3570X is currently in active production status, ensuring long-term availability.

The ERA-2AEC3570X incorporates AEC-Q200 automotive qualification, which provides additional reliability assurance through automotive-grade testing protocols. The extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) offers enhanced thermal margin for applications operating at elevated temperatures. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings.

Selection of the ERA-2AEC3570X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs originally specified for the ERA-2HEC3570P.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC3570X be used as a direct replacement for ERA-2HEC3570P?

A: Yes. Both components have identical resistance (357 Ohms), tolerance (±0.25%), power rating (0.063W), composition (thin film), and package (0402). The ERA-2AEC3570X is electrically and mechanically interchangeable.

Q: What is the difference between ERA-2H and ERA-2A series?

A: The ERA-2A series includes AEC-Q200 automotive qualification and extended temperature rating (155°C maximum versus 125°C). The ERA-2H series is the standard industrial grade without automotive qualification.

Q: Does the extended temperature range of ERA-2AEC3570X affect circuit performance?

A: No. The temperature coefficient (±25ppm/°C) is identical for both parts. The extended range indicates the component is rated for operation up to 155°C, but does not change its performance characteristics within the original operating range.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC3570P and ERA-2AEC3570X are ROHS3 compliant.

Q: What is the physical footprint compatibility?

A: Both components use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB layouts require no modification.
