Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC93R1P is determined by the following critical parameters:

• Resistance value: 93.1 Ohms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W minimum (1/16W)
• 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)
• Moisture sensitivity: MSL 1 or better

The ERA-2AEC93R1X meets all substitution criteria. This part maintains identical electrical specifications, package dimensions, and environmental ratings while offering active product status and extended operating temperature range (-55°C to 155°C). The ERA-2AEC93R1X includes AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC93R1X is the direct substitute for the obsolete ERA-2HEC93R1P. Both parts are manufactured by Panasonic Electronic Components and share identical electrical and mechanical specifications within the critical parameters: 93.1 Ohms resistance, ±0.25% tolerance, 0.063W power rating, 0402 package, thin film composition, and ±25ppm/°C temperature coefficient.

The ERA-2AEC93R1X offers the advantage of active product status, ensuring continued availability and supply chain support. The extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) provides additional thermal margin for applications operating at elevated temperatures. AEC-Q200 automotive qualification on the ERA-2AEC93R1X indicates compliance with automotive reliability standards and is applicable for both automotive and general industrial applications.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC93R1X be used as a direct replacement for ERA-2HEC93R1P in existing designs?

A: Yes. The ERA-2AEC93R1X is a direct substitute. Both parts have identical resistance (93.1 Ohms), tolerance (±0.25%), power rating (0.063W), package (0402), composition (thin film), and temperature coefficient (±25ppm/°C). The ERA-2AEC93R1X can be substituted without design modification.

Q: What is the difference between ERA-2HEC and ERA-2AEC series?

A: The ERA-2HEC series represents the standard thin film resistor line, while the ERA-2AEC series is the automotive-qualified variant with AEC-Q200 certification. Both series share identical electrical specifications for equivalent part numbers. The ERA-2AEC series is suitable for applications requiring automotive-grade reliability.

Q: Does the extended temperature range of ERA-2AEC93R1X affect compatibility?

A: No. The extended operating temperature range (-55°C to 155°C) of the ERA-2AEC93R1X is a superset of the ERA-2HEC93R1P range (-55°C to 125°C). This provides additional thermal margin and does not create compatibility issues in applications operating within the original specification range.

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: What is the inventory status for these parts?

A: ERA-2HEC93R1P (obsolete): 732 Pcs in stock. ERA-2AEC93R1X (active): 772 Pcs in stock. The active status of ERA-2AEC93R1X ensures continued availability for future procurement.
