Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FAD200K are classified based on the following substitution criteria:

Direct Substitutes (Same Electrical Specifications):

• RNF14FTD200K: Identical electrical parameters (200 kOhms ±1%, 0.25W) and composition. Differs only in packaging format (Cut Tape vs. Tape & Box).

Upgrade Substitutes (Enhanced Specifications):

• CMF55200K00BEEB, CMF55200K00BHEB, CMF55200K00FHEB: All manufactured by Vishay Dale with improved power rating (0.5W vs. 0.25W), enhanced temperature coefficient performance, and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). These parts maintain the 200 kOhms resistance value and axial package configuration. Tolerance variations exist: CMF55200K00BEEB and CMF55200K00BHEB offer ±0.1% tolerance (tighter than original ±1%), while CMF55200K00FHEB maintains ±1% tolerance.

All substitute parts are ROHS3 compliant, feature flame retardant coating and safety characteristics, and are actively produced.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required): RNF14FTD200K is the optimal choice when packaging format flexibility is acceptable. It maintains identical electrical and thermal specifications to the RNF14FAD200K while offering higher inventory availability (65,690 pcs vs. 1,054 pcs). Both parts are manufactured by Stackpole Electronics Inc and carry ROHS3 compliance.

For Enhanced Performance Applications: The Vishay Dale CMF55 series substitutes (CMF55200K00BEEB, CMF55200K00BHEB, CMF55200K00FHEB) provide upgraded specifications suitable for applications requiring higher power dissipation capability (0.5W vs. 0.25W), improved temperature stability, and extended operating temperature range. CMF55200K00BEEB offers the tightest tolerance specification (±0.1%) with the lowest temperature coefficient (±25ppm/°C), making it suitable for precision measurement circuits. CMF55200K00FHEB maintains the original ±1% tolerance while providing the power and temperature benefits of the CMF55 series.

All substitute parts maintain ROHS3 compliance and active production status, ensuring long-term availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD200K be used as a direct replacement for RNF14FAD200K? A: Yes. Both parts share identical electrical specifications (200 kOhms ±1%, 0.25W), composition (metal film), and operating temperature range (-55°C ~ 155°C). The only difference is packaging format: RNF14FAD200K is supplied in Tape & Box format while RNF14FTD200K is supplied in Cut Tape format. Electrical and mechanical performance are equivalent.

Q: What are the advantages of using CMF55 series substitutes? A: CMF55 series resistors offer three primary advantages: (1) higher power rating (0.5W vs. 0.25W) allowing operation in higher dissipation environments, (2) improved temperature coefficient performance (±25ppm/°C to ±50ppm/°C vs. ±100ppm/°C) for better stability across temperature variations, and (3) extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). Additionally, CMF55 parts include moisture-resistant features.

Q: Are all substitute parts physically compatible with the original PCB layout? A: All substitute parts use the axial package configuration with identical termination count (2 leads). Physical dimensions are comparable: RNF14FAD200K measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm), while CMF55 series measures 0.090" Dia x 0.240" L (2.29mm x 6.10mm). These minor dimensional variations are within standard PCB design tolerances for through-hole axial components and do not require layout modifications.

Q: Which substitute part should be selected for precision applications? A: CMF55200K00BEEB is recommended for precision applications requiring tight tolerance specifications. It provides ±0.1% tolerance (compared to ±1% of the original part) and the lowest temperature coefficient (±25ppm/°C), ensuring superior resistance value stability across operating conditions.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (RNF14FTD200K, CMF55200K00BEEB, CMF55200K00BHEB, CMF55200K00FHEB) are ROHS3 compliant, matching the compliance status of the RNF14FAD200K.
