Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC2430P is determined by strict equivalence across the following parameters:

• Resistance value: 243 Ohms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power rating: 0.063W, 1/16W (electrical stress limit)
• Composition: Thin Film (performance characteristics)
• Package: 0402 (1005 Metric) (physical and thermal compatibility)
• Temperature coefficient: ±25ppm/°C (frequency stability)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The ERA-2AEC2430X meets all these criteria while offering an active product status and extended operating temperature range, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC2430X is a direct substitute for the ERA-2HEC2430P based on identical electrical and mechanical specifications. The substitute part offers the following advantages:

• Active product status ensures continued availability and supply chain stability
• Extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides additional thermal margin for applications operating at elevated temperatures
• AEC-Q200 automotive qualification provides enhanced reliability documentation
• Identical thin film composition, tolerance, and temperature coefficient ensure equivalent performance in precision analog circuits
• Same 0402 package footprint and termination configuration enable direct PCB layout compatibility

Both parts maintain ROHS3 compliance and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC2430X be used as a direct replacement for ERA-2HEC2430P in existing designs?

A: Yes. Both parts share identical resistance (243 Ohms), tolerance (±0.25%), power rating (0.063W), composition (thin film), package (0402), temperature coefficient (±25ppm/°C), and RoHS compliance. The substitute part is electrically and mechanically equivalent for standard applications within the -55°C ~ 125°C range.

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

A: The ERA-2A series includes AEC-Q200 automotive qualification and extends the maximum operating temperature to 155°C, compared to 125°C for the ERA-2H series. Both series use identical thin film technology and meet the same precision and tolerance specifications.

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

A: No. Both the ERA-2HEC2430P and ERA-2AEC2430X use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and height (0.016" / 0.40mm maximum). PCB layouts and assembly processes require no modification.

Q: Does the extended temperature range of ERA-2AEC2430X affect circuit performance?

A: The extended operating range (-55°C ~ 155°C) does not alter the component's performance within the original design temperature window (-55°C ~ 125°C). The temperature coefficient remains ±25ppm/°C for both parts, ensuring equivalent frequency stability and resistance drift characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC2430P and ERA-2AEC2430X are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), confirming compatibility with standard lead-free manufacturing and storage protocols.
