Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERA-2HEC1601P is determined by the following critical parameters:

• Resistance Value: 1.6 kOhms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power Rating: 0.063W, 1/16W (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)

The ERA-2AEC1601X meets all critical electrical and mechanical parameters. The primary difference is the operating temperature range extension and automotive AEC-Q200 qualification, which represents an enhancement rather than a limitation for general applications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1601X is a direct substitute for the ERA-2HEC1601P based on matching electrical specifications and package dimensions. The ERA-2AEC1601X offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and AEC-Q200 automotive qualification provide enhanced performance margins for applications operating at elevated temperatures. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The ERA-2AEC1601X is suitable for direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC1601X replace the ERA-2HEC1601P in all applications?

A: Yes. The ERA-2AEC1601X matches all critical electrical parameters (resistance, tolerance, power rating, temperature coefficient) and physical dimensions (0402 package). The extended operating temperature range and automotive qualification represent performance enhancements.

Q: What is the significance of the AEC-Q200 qualification on the ERA-2AEC1601X?

A: AEC-Q200 is an automotive industry standard qualification. This certification indicates the part meets automotive reliability and quality requirements. For non-automotive applications, this qualification does not impose restrictions and provides additional quality assurance.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts 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 footprints are identical.

Q: Why is the ERA-2HEC1601P listed as obsolete?

A: The ERA-2HEC1601P has been discontinued by Panasonic Electronic Components. The ERA-2AEC1601X represents the active product line continuation with equivalent electrical performance.

Q: Are the tolerance and temperature coefficient specifications identical?

A: Yes. Both parts specify ±0.25% tolerance and ±25ppm/°C temperature coefficient, ensuring equivalent precision and thermal stability characteristics.
