ERA-2ARC1471X Equivalent & Substitute Parts

Part Overview

The ERA-2ARC1471X is a 1.47 kOhms ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated for 0.063W (1/16W) power dissipation. This component is manufactured by Panasonic Electronic Components and meets AEC-Q200 automotive qualification standards. The part is actively produced and available in high volume inventory (1399 pcs in stock).

Substitute parts are identified when electrical specifications, mechanical dimensions, and compliance ratings remain within acceptable tolerances for direct circuit board replacement without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Electrical Compatibility Requirements:

• Resistance value must be 1.47 kOhms
• Tolerance must be equal to or tighter than ±0.25%
• Power rating must be equal to or greater than 0.063W
• Composition must be thin film
• Temperature coefficient must be ±10ppm/°C or better
• Operating temperature range must encompass -55°C to 155°C

Mechanical Compatibility Requirements:

• Package must be 0402 (1005 Metric)
• Physical dimensions must not exceed 0.039" L x 0.020" W
• Height must not exceed 0.016" (0.40mm) seated maximum
• Two terminations required

Compliance Requirements:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

Two substitute parts meet these criteria:

1. ERA-2ARB1471X (Panasonic) — Upgrade variant with improved tolerance (±0.1% vs ±0.25%)
2. RN73C1E1K47BTDF (TE Connectivity) — Cross-manufacturer equivalent with ±0.1% tolerance

Parameter Comparison

Engineering Selection Recommendations

ERA-2ARB1471X Selection Criteria: This Panasonic upgrade variant is suitable when tighter tolerance specifications are required. The ±0.1% tolerance provides improved accuracy compared to the ±0.25% main part while maintaining identical electrical and mechanical characteristics. Both parts carry identical AEC-Q200 automotive qualification and ROHS3 compliance. Higher inventory availability (8825 pcs) supports production continuity.

RN73C1E1K47BTDF Selection Criteria: This TE Connectivity cross-manufacturer equivalent meets all electrical and mechanical requirements with ±0.1% tolerance. The seated height is 0.014" (0.35mm), which is lower than the maximum specification, providing additional clearance margin in space-constrained layouts. ROHS3 compliance and MSL 1 rating are maintained. This option is suitable for supply chain diversification or when TE Connectivity components are preferred within the design ecosystem.

Substitution Constraints: All three parts are electrically and mechanically interchangeable within the specified parameter boundaries. Selection should be based on tolerance requirements, inventory availability, and supply chain strategy rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARB1471X replace ERA-2ARC1471X in existing designs? A: Yes. The ERA-2ARB1471X is a direct substitute with improved tolerance (±0.1% vs ±0.25%). All electrical, mechanical, and compliance parameters are identical or superior. No circuit redesign is required.

Q: Is RN73C1E1K47BTDF compatible with the original ERA-2ARC1471X? A: Yes. The RN73C1E1K47BTDF meets all electrical and mechanical specifications. The 0402 package dimensions and power rating are identical. The seated height is 0.014" (0.35mm), which is within the maximum specification of 0.016" (0.40mm).

Q: What is the significance of tolerance differences between ±0.25% and ±0.1%? A: Tolerance defines the maximum deviation from the nominal 1.47 kOhms resistance value. ±0.25% allows deviation up to ±3.675 Ohms, while ±0.1% limits deviation to ±1.47 Ohms. Tighter tolerance is beneficial in precision analog circuits, measurement applications, and high-accuracy voltage dividers.

Q: Are all three parts AEC-Q200 qualified? A: ERA-2ARC1471X and ERA-2ARB1471X carry explicit AEC-Q200 automotive qualification. RN73C1E1K47BTDF does not list AEC-Q200 qualification in the provided specifications. For automotive applications requiring AEC-Q200 certification, Panasonic variants are the appropriate selection.

Q: What is the difference between Tape & Reel (TR) packaging? A: All three parts are supplied in Tape & Reel format, which is standard for automated surface mount assembly. This packaging format is identical across all three parts and does not affect substitution eligibility.

Q: Can these parts be used interchangeably in high-temperature applications? A: Yes. All three parts maintain the same operating temperature range of -55°C to 155°C and identical temperature coefficient of ±10ppm/°C. No performance degradation occurs when substituting between these parts in this temperature range.

Q: What does MSL 1 (Unlimited) mean for component handling? A: MSL 1 indicates Moisture Sensitivity Level 1, which means unlimited shelf life without moisture baking requirements. All three parts carry this rating, eliminating moisture-related handling constraints during storage and assembly.
