Substitute Part Grouping Explanation

The RNF18FAD47K5 has one direct equivalent substitute: RNF18FTD47K5. Both parts are manufactured by Stackpole Electronics Inc within the RNF series and share identical electrical and mechanical specifications. The substitution is valid based on the following matching parameters:

• Resistance value: 47.5 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Package configuration: Axial
• Physical dimensions: 0.071" Dia x 0.130" L (1.80mm x 3.30mm)
• Termination count: 2
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The only difference between these parts is the packaging format: RNF18FAD47K5 is supplied in Tape & Box (TB) format, while RNF18FTD47K5 is supplied in Cut Tape (CT) format. Both formats contain identical components suitable for automated assembly or manual placement applications.

Parameter Comparison

Engineering Selection Recommendations

Both RNF18FAD47K5 and RNF18FTD47K5 are suitable for direct substitution in applications requiring a 47.5 kOhms ±1% metal film resistor with 0.125W power rating and axial through-hole configuration. Selection between these parts should be based on procurement requirements and assembly methodology:

• RNF18FAD47K5 (Tape & Box format) is appropriate for applications requiring bulk quantities with protective packaging for storage and manual assembly operations.
• RNF18FTD47K5 (Cut Tape format) is appropriate for automated pick-and-place assembly systems and high-volume production environments.

Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance across all specified operating conditions. The choice between packaging formats does not affect circuit functionality or reliability.

Frequently Asked Questions (FAQ)

Q: Can RNF18FTD47K5 be used as a direct replacement for RNF18FAD47K5?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Box). The resistor component itself is identical in all electrical and physical specifications.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging supplies components on continuous tape wound on a reel and packaged in a protective box, suitable for manual assembly and storage. Cut Tape packaging supplies components on tape segments cut to specific lengths, optimized for automated assembly equipment. Both formats contain the same component.

Q: Are there any compatibility issues when substituting between these part numbers?

A: No compatibility issues exist. Both parts have identical axial package dimensions (0.071" Dia x 3.30mm length), two terminations, and fit standard through-hole PCB layouts identically. Substitution is valid for all circuit applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RNF18FAD47K5 and RNF18FTD47K5 are ROHS3 compliant and REACH unaffected, with identical regulatory certifications.

Q: What is the temperature coefficient specification and how does it affect circuit performance?

A: Both parts have a temperature coefficient of ±100ppm/°C. This means the resistance value changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. Across the full operating range of -55°C to 155°C (210°C span), the maximum resistance drift is approximately 2.1%, which combines with the ±1% tolerance for total worst-case tolerance of approximately ±3.1%.
