ERA-2HRC2430X Equivalent & Substitute Parts

Part Overview

The ERA-2HRC2430X is a 243 Ohm ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated at 0.063W (1/16W). This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The ERA-2HRC series has been superseded by the ERA-2A automotive-grade line, which maintains electrical equivalence while offering extended temperature range and active product status.

Key Parameters

Substitute Part Grouping Explanation

The ERA-2ARC2430X qualifies as a direct electrical and mechanical substitute based on the following matching parameters:

• Resistance value: 243 Ohms (identical)
• Tolerance: ±0.25% (identical)
• Power rating: 0.063W, 1/16W (identical)
• Composition: Thin Film (identical)
• Package: 0402 (1005 Metric) (identical)
• Temperature coefficient: ±10ppm/°C (identical)
• Physical dimensions: 0.039" L x 0.020" W, 0.016" max height (identical)
• Termination count: 2 (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• MSL rating: 1 (Unlimited) (identical)

The ERA-2ARC2430X represents an upgrade path from the obsolete ERA-2HRC series, incorporating automotive-grade AEC-Q200 qualification and an extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC2430X is the appropriate substitute for the obsolete ERA-2HRC2430X. Both components share identical electrical specifications (243 Ohms, ±0.25% tolerance, 0.063W power rating, ±10ppm/°C temperature coefficient) and mechanical compatibility (0402 package, identical dimensions).

The ERA-2ARC2430X offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• AEC-Q200 automotive qualification provides additional reliability assurance
• Extended operating temperature range (-55°C ~ 155°C) accommodates broader thermal environments
• ROHS3 compliance maintained across both parts
• Identical MSL rating (1, Unlimited) eliminates moisture sensitivity concerns

For applications requiring only the base temperature range of -55°C ~ 125°C, the ERA-2ARC2430X remains fully compatible and suitable for direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARC2430X directly replace ERA-2HRC2430X in existing designs?

A: Yes. Both components are electrically and mechanically identical across all critical parameters: resistance value, tolerance, power rating, temperature coefficient, and 0402 package dimensions. Direct substitution is possible without circuit modification.

Q: What is the significance of the AEC-Q200 rating on the ERA-2ARC2430X?

A: AEC-Q200 is an automotive industry qualification standard. The ERA-2ARC2430X meets this standard, indicating compliance with automotive reliability and quality requirements. This qualification is not present on the obsolete ERA-2HRC2430X but does not restrict use in non-automotive applications.

Q: Does the extended temperature range of ERA-2ARC2430X (-55°C ~ 155°C) affect compatibility?

A: No. The extended upper temperature limit of 155°C (versus 125°C on the ERA-2HRC2430X) represents an enhancement. Applications operating within the original -55°C ~ 125°C range experience no adverse effects from this specification change.

Q: Are there packaging differences between these parts?

A: The ERA-2HRC2430X is listed without specified packaging, while the ERA-2ARC2430X is supplied in Tape & Reel (TR) format. Both use identical 0402 (1005 Metric) package geometry. Tape & Reel packaging is standard for SMD component distribution and does not affect component performance or PCB assembly compatibility.

Q: What is the inventory status for these parts?

A: The ERA-2HRC2430X is obsolete with 957 pieces available. The ERA-2ARC2430X is active with 2044 pieces in stock, providing superior supply chain security for new designs and ongoing production.
