Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERA-2HRC3241P is determined by the following critical parameters:

• Resistance Value: 3.24 kOhms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power Rating: 0.063W, 1/16W (electrical stress rating)
• Package Type: 0402 (1005 Metric) (physical and footprint compatibility)
• Composition: Thin Film (performance characteristics)
• Temperature Coefficient: ±10ppm/°C (stability specification)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The ERA-2ARC3241X qualifies as a direct substitute because it matches all critical electrical and mechanical parameters while offering an active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC3241X is the qualified substitute for the obsolete ERA-2HRC3241P. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications and physical dimensions. The ERA-2ARC3241X offers the following advantages:

• Active Product Status: Currently in production with confirmed inventory availability (1203 Pcs)
• Extended Operating Temperature Range: Rated to 155°C versus 125°C for the original part, providing additional thermal margin
• Automotive Qualification: AEC-Q200 certified, meeting automotive reliability standards
• Regulatory Compliance: ROHS3 compliant with REACH unaffected status
• Identical Footprint: Direct PCB layout compatibility with no design modifications required

The ERA-2ARC3241X maintains all critical electrical parameters including resistance value, tolerance, power rating, temperature coefficient, and composition, ensuring functional equivalence in all applications where the ERA-2HRC3241P was specified.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2ARC3241X be used as a direct replacement for ERA-2HRC3241P without PCB modifications?

A: Yes. Both parts share identical package dimensions (0402/1005 Metric), footprint, and electrical specifications. No PCB layout changes are required.

Q: What is the significance of the AEC-Q200 qualification on the ERA-2ARC3241X?

A: AEC-Q200 is an automotive industry standard for passive components. This certification indicates the part meets automotive reliability and quality requirements. It does not restrict use in non-automotive applications.

Q: Why does the ERA-2ARC3241X have a higher maximum operating temperature (155°C vs 125°C)?

A: The ERA-2ARC3241X is rated for a wider operating temperature range. This extended upper limit provides additional thermal headroom and does not affect compatibility with designs specified for the lower temperature range.

Q: Are there any differences in packaging between these parts?

A: The ERA-2HRC3241P is supplied in standard packaging, while the ERA-2ARC3241X is supplied in Tape & Reel (TR) format. Both contain identical components; packaging format affects only handling and assembly processes.

Q: What is the tolerance specification and why is ±0.25% significant?

A: Both parts are specified at ±0.25% tolerance, which is a precision thin film specification. This tight tolerance is maintained across both the obsolete and substitute parts, ensuring equivalent performance in precision circuit applications.

Q: Is the ERA-2ARC3241X suitable for high-reliability applications?

A: Yes. The part is ROHS3 compliant, MSL 1 rated (unlimited moisture sensitivity), and AEC-Q200 qualified, making it suitable for high-reliability and automotive applications.
