Key Parameters

Substitute Part Grouping Explanation

The RNF18FAD5K11 and RNF18FTD5K11 are functionally equivalent components within the Stackpole RNF series. Substitution eligibility is determined by the following critical parameters:

• Resistance value: 5.11 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Package configuration: Axial (exact match required)
• Physical dimensions: 0.071" Dia × 0.130" L (exact match required)

The primary distinction between these parts is packaging format: RNF18FAD5K11 is supplied in Tape & Box (TB) format, while RNF18FTD5K11 is supplied in Cut Tape (CT) format. Both maintain identical electrical performance and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both RNF18FAD5K11 and RNF18FTD5K11 are Active status components with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain considerations:

RNF18FAD5K11 (Tape & Box format) is appropriate for applications requiring boxed component quantities with standard tape packaging.

RNF18FTD5K11 (Cut Tape format) is appropriate for applications requiring cut tape delivery or when cut tape packaging aligns with assembly process requirements.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance for industrial and commercial applications. The identical resistance value, tolerance, power rating, temperature coefficient, and operating temperature range guarantee direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RNF18FTD5K11 be used as a direct replacement for RNF18FAD5K11?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: RNF18FAD5K11 uses Tape & Box (TB) format while RNF18FTD5K11 uses Cut Tape (CT) format. Circuit performance is unaffected by this packaging distinction.

Q: What determines whether a substitute part is acceptable?

A: Substitution eligibility requires exact matching of: resistance value (5.11 kOhms), tolerance (±1%), power rating (0.125W), composition (Metal Film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), package type (Axial), and physical dimensions (0.071" Dia × 0.130" L).

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status and REACH Unaffected designation. Regulatory compliance is equivalent across both part numbers.

Q: Does packaging format affect circuit performance?

A: No. Tape & Box and Cut Tape formats are delivery and handling methods only. Electrical and mechanical performance characteristics remain identical regardless of packaging format.

Q: What is the operating temperature range for these resistors?

A: Both parts operate across -55°C to 155°C with a temperature coefficient of ±100ppm/°C, ensuring stable resistance values across this temperature range.
