Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF18FAD33K2 are identified based on strict equivalence of the following electrical and mechanical parameters:

• Resistance value: 33.2 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Package type: Axial
• 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)
• Termination count: 2
• Compliance: RoHS3 Compliant

The primary difference between the main part and its substitute is the packaging format: Tape & Box (TB) versus Cut Tape (CT). Both variants maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both RNF18FAD33K2 and RNF18FTD33K2 are Active products manufactured by Stackpole Electronics Inc with identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and supply chain considerations rather than technical performance.

The RNF18FAD33K2 (Tape & Box packaging) is suitable for applications requiring bulk component storage and manual assembly workflows. The RNF18FTD33K2 (Cut Tape packaging) is appropriate for automated pick-and-place assembly processes and applications with component-level inventory management.

Both parts maintain full RoHS3 compliance and are suitable for operating environments spanning -55°C to 155°C. The identical physical dimensions, electrical ratings, and safety features ensure direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RNF18FTD33K2 be used as a direct replacement for RNF18FAD33K2?

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

Q: What determines substitution eligibility for RNF18FAD33K2?

A: Substitute parts must match all electrical parameters (33.2 kOhms ±1%, 0.125W, ±100ppm/°C), composition (metal film), package type (axial), physical dimensions (0.071" Dia x 0.130" L), and compliance certifications (RoHS3).

Q: Are there differences in reliability or failure rates between these parts?

A: No reliability or failure rate data is provided for either part. Both are manufactured by the same supplier using identical specifications and are Active products with equivalent compliance status.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Tape & Box or Cut Tape) affects only supply chain logistics and assembly methodology. Electrical performance and mechanical fit are identical.

Q: What is the significance of the flame retardant coating?

A: The flame retardant coating and safety features are standard specifications for both parts. These features are maintained across all substitute variants.
