Substitute Part Grouping Explanation

Substitute parts for the RNF18FAD9K09 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Resistance value: 9.09 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Package: Axial through-hole
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Physical dimensions: 0.071" Dia x 0.130" L (1.80mm x 3.30mm)
• Compliance: ROHS3 Compliant, REACH Unaffected

The identified substitute differs only in packaging format (Cut Tape versus Tape & Box), which does not affect electrical or mechanical performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF18FAD9K09 and RNF18FTD9K09 are functionally equivalent for circuit applications. Selection between these parts is determined by procurement and assembly requirements rather than electrical performance:

The RNF18FAD9K09 in Tape & Box packaging is suitable for applications requiring boxed component quantities with protective packaging for storage and distribution.

The RNF18FTD9K09 in Cut Tape packaging is suitable for high-volume automated assembly operations and applications where component tape format is preferred for pick-and-place equipment.

Both parts maintain identical electrical characteristics, compliance certifications, and thermal performance across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RNF18FTD9K09 be used as a direct replacement for RNF18FAD9K09?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Box). Circuit performance is unaffected by this packaging distinction.

Q: What determines compatibility between these substitute parts?

A: Compatibility is based on matching resistance value (9.09 kOhms), tolerance (±1%), power rating (0.125W), composition (metal film), package type (axial), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and physical dimensions (0.071" Dia x 0.130" L).

Q: Are there any compliance differences between the main part and substitute?

A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status. Regulatory and environmental certifications are equivalent.

Q: Which packaging format should be selected for my application?

A: Tape & Box (TB) packaging is standard for manual assembly and component storage. Cut Tape (CT) packaging is optimized for automated pick-and-place assembly lines. Select based on your assembly process requirements.

Q: Do these parts have the same thermal performance?

A: Yes. Both parts share identical temperature coefficient (±100ppm/°C) and operating temperature range (-55°C to 155°C), ensuring equivalent thermal stability and performance across environmental conditions.
