Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HRC3161P is determined by strict equivalence across the following parameters:

• Resistance value: 3.16 kOhms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Termination count: 2

The ERA-2ARC3161X meets all these criteria and qualifies as a direct substitute. The ERA-2ARC series incorporates automotive-grade AEC-Q200 qualification and extends the upper operating temperature to 155°C, providing enhanced reliability margins while maintaining identical electrical and mechanical specifications for the core application parameters.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC3161X is the qualified substitute for the obsolete ERA-2HRC3161P. Both parts are manufactured by Panasonic Electronic Components and share identical electrical and mechanical specifications for resistance, tolerance, power rating, package dimensions, and temperature coefficient.

The ERA-2ARC3161X offers the advantage of active product status with continued manufacturing support. The part carries AEC-Q200 automotive qualification and extends the maximum operating temperature from 125°C to 155°C, providing additional thermal margin for demanding applications. Both parts maintain ROHS3 compliance and MSL 1 rating.

Selection between these parts depends on application requirements: the ERA-2HRC3161P may be used where existing inventory is available, while the ERA-2ARC3161X is recommended for new designs and ongoing production due to its active status and automotive-grade reliability certification.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARC3161X replace ERA-2HRC3161P in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all core parameters: 3.16 kOhms ±0.25%, 0.063W power rating, 0402 package, thin film composition, and ±10ppm/°C temperature coefficient. The ERA-2ARC3161X is a direct substitute with no design modifications required.

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

A: The ERA-2H series represents the standard thin film resistor line. The ERA-2A series incorporates automotive-grade AEC-Q200 qualification and extends the upper operating temperature limit to 155°C compared to 125°C for the ERA-2H series. Electrical specifications remain identical.

Q: Are the physical dimensions identical?

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

Q: What is the significance of AEC-Q200 qualification?

A: AEC-Q200 is an automotive industry standard qualification for passive components. The ERA-2ARC3161X meets this specification, indicating compliance with automotive reliability and quality requirements. This qualification is beneficial for applications requiring enhanced reliability assurance, though not mandatory for non-automotive use.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HRC3161P and ERA-2ARC3161X are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

Q: Why is ERA-2HRC3161P listed as obsolete?

A: The ERA-2HRC3161P has been discontinued by Panasonic Electronic Components. The ERA-2ARC3161X represents the active replacement with equivalent specifications and enhanced automotive qualification, ensuring continued availability and manufacturing support.
