Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HRC1020X is determined by strict equivalence across the following parameters:

• Resistance value: 102 Ohms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-2ARC1020X meets all these criteria and qualifies as a direct substitute. The primary distinction is the addition of AEC-Q200 automotive qualification and an extended upper operating temperature limit of 155°C versus 125°C on the original part.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC1020X is a direct functional equivalent to the obsolete ERA-2HRC1020X. Both components share identical electrical specifications, package dimensions, and thermal characteristics within the ERA-2HRC1020X operating range. The ERA-2ARC1020X is currently in active production status, ensuring supply chain availability.

The ERA-2ARC1020X incorporates AEC-Q200 automotive qualification and extends the maximum operating temperature to 155°C. For applications operating within the original -55°C to 125°C range, the ERA-2ARC1020X provides equivalent performance with enhanced reliability margins. Applications requiring operation above 125°C should evaluate the extended temperature capability of the substitute part against specific design requirements.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2ARC1020X be used as a direct replacement for ERA-2HRC1020X in existing designs?

A: Yes. Both parts are 102 Ohm ±0.25% thin film resistors in 0402 package with identical electrical and mechanical specifications within the ERA-2HRC1020X operating range. PCB layout and assembly processes require no modification.

Q: What is the significance of AEC-Q200 qualification on the ERA-2ARC1020X?

A: AEC-Q200 is an automotive industry qualification standard. The ERA-2ARC1020X meets this standard; however, this qualification does not affect electrical performance or compatibility in non-automotive applications.

Q: Are there dimensional differences between these parts?

A: No. Both parts are 0402 (1005 Metric) package with identical length, width, and maximum seated height specifications.

Q: Does the extended temperature range of the ERA-2ARC1020X affect its use in applications limited to -55°C to 125°C?

A: No. The extended upper temperature limit of 155°C on the ERA-2ARC1020X does not impact performance in applications operating within the original -55°C to 125°C range.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HRC1020X and ERA-2ARC1020X are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
