RN73C2B47K5BTDF Equivalent & Substitute Parts

Part Overview

The RN73C2B47K5BTDF is a 47.5 kOhms ±0.1% thin film chip resistor manufactured by TE Connectivity Passive Product in the 1206 (3216 Metric) package format. This surface mount device is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The component is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent resistance values, tolerance specifications, and package dimensions are maintained while offering alternative performance characteristics such as increased power ratings or enhanced automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

RN73C2B47K5BTDF (TE Connectivity): Select this part for applications requiring the specified 0.125W power rating with standard industrial tolerance of ±0.1%. The component maintains active production status with ROHS3 compliance and is suitable for general-purpose circuit applications across the full operating temperature range.

ERA-8ARB4752V (Panasonic - AEC-Q200, ±0.1% Tolerance): This substitute provides doubled power handling capacity (0.25W) while maintaining the same ±0.1% tolerance specification. The addition of AEC-Q200 automotive qualification makes this part suitable for automotive and high-reliability applications. Select this option when increased thermal margin or automotive-grade reliability is required without tightening tolerance specifications.

ERA-8ARW4752V (Panasonic - AEC-Q200, ±0.05% Tolerance): This substitute offers both increased power rating (0.25W) and enhanced tolerance specification (±0.05%). The tighter tolerance combined with AEC-Q200 automotive qualification addresses applications requiring superior precision and automotive-grade reliability. Select this option for precision analog circuits or automotive systems where tolerance stack-up must be minimized.

All substitute parts maintain identical package dimensions, thermal characteristics, and environmental operating ranges, ensuring direct mechanical and electrical compatibility within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARB4752V or ERA-8ARW4752V be used as direct replacements for RN73C2B47K5BTDF?

A: Yes. Both Panasonic parts maintain the same 47.5 kOhms resistance value, 1206 package format, thin film composition, and operating temperature range. The increased power rating (0.25W versus 0.125W) and automotive qualification represent enhancements rather than deviations from the original specification.

Q: What is the difference between ERA-8ARB4752V and ERA-8ARW4752V?

A: Both parts share identical power ratings (0.25W), package format (1206), and automotive qualification (AEC-Q200). The primary difference is tolerance specification: ERA-8ARB4752V maintains ±0.1% tolerance matching the original part, while ERA-8ARW4752V provides tighter ±0.05% tolerance for precision applications.

Q: Are there any physical dimension differences between the main part and substitutes?

A: Minor dimensional variations exist within the 1206 package family. The main part measures 0.120" L x 0.061" W with 0.026" maximum seated height. Substitute parts measure 0.126" L x 0.063" W with 0.028" maximum seated height. These variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. It certifies that the component meets stringent reliability, temperature cycling, and performance requirements for automotive applications. This qualification is not present on the original RN73C2B47K5BTDF but is included on both Panasonic substitute parts.

Q: Can I use a substitute part with higher power rating in a circuit designed for 0.125W?

A: Yes. A component rated for 0.25W can operate safely in a circuit designed for 0.125W. The higher power rating provides additional thermal margin and does not affect electrical performance. The component will dissipate only the power required by the circuit.

Q: Are all parts ROHS3 compliant?

A: Yes. The main part RN73C2B47K5BTDF and both substitute parts (ERA-8ARB4752V and ERA-8ARW4752V) are ROHS3 compliant. The Panasonic substitutes additionally carry REACH Unaffected status, providing enhanced regulatory documentation.

Q: What is the significance of ±10ppm/°C temperature coefficient?

A: The temperature coefficient of ±10ppm/°C specifies the maximum resistance change per degree Celsius across the operating temperature range. All three parts share this identical specification, ensuring equivalent thermal stability performance.
