Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FAD20K0 are grouped based on the following substitution criteria:

Direct Equivalent (Same Electrical & Mechanical Specifications):

• RNF14FTD20K0: Identical electrical parameters and axial package configuration. Difference is packaging format (Cut Tape vs. Tape & Box).

Upgraded Alternatives (Enhanced Specifications):

• CMF5520K000BEEB, CMF5520K000BEEK, CMF5520K000BHEB, CMF5520K000FHEB: These Vishay Dale CMF series resistors maintain the 20 kOhms resistance value and axial package but offer enhanced performance characteristics including higher power rating (0.5W vs. 0.25W), improved tolerance (±0.1% for select models), lower temperature coefficient (±25ppm/°C to ±50ppm/°C vs. ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C).

All substitute parts maintain metal film composition, axial through-hole configuration, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): RNF14FTD20K0 is the direct equivalent to RNF14FAD20K0. Both parts share identical electrical and thermal characteristics. Selection between these two is determined by packaging requirements: RNF14FAD20K0 is supplied in Tape & Box format, while RNF14FTD20K0 is supplied in Cut Tape format.

For Upgraded Performance: The CMF series resistors (CMF5520K000BEEB, CMF5520K000BEEK, CMF5520K000BHEB, CMF5520K000FHEB) are suitable when enhanced specifications are required. These parts provide higher power dissipation capability (0.5W vs. 0.25W), improved temperature stability (lower temperature coefficient), and extended operating temperature range. All CMF series parts maintain ROHS3 compliance and axial package compatibility. Physical dimensions are slightly reduced (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L), which may be advantageous in space-constrained applications.

All substitute parts are Active status products with current manufacturing availability.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD20K0 be used as a direct replacement for RNF14FAD20K0? A: Yes. RNF14FTD20K0 is a direct equivalent with identical electrical specifications (20 kOhms ±1%, 0.25W, ±100ppm/°C) and axial package configuration. The only difference is the packaging format (Cut Tape vs. Tape & Box).

Q: What are the key differences between the Stackpole RNF series and Vishay Dale CMF series substitutes? A: The CMF series resistors offer enhanced specifications: higher power rating (0.5W vs. 0.25W), improved tolerance options (±0.1% available), lower temperature coefficient (±25ppm/°C to ±50ppm/°C vs. ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). Physical dimensions are slightly smaller.

Q: Are there any mechanical compatibility concerns when substituting CMF series parts? A: CMF series resistors have slightly reduced physical dimensions (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L). Both maintain axial through-hole package configuration and 2-termination design. Verify PCB layout clearances if space margins are critical.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All listed substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, matching the compliance profile of the RNF14FAD20K0.

Q: Which substitute part should be selected for high-temperature applications? A: CMF series resistors support operating temperatures up to 175°C, compared to 155°C for the RNF14FAD20K0. Select CMF5520K000BEEB or CMF5520K000BEEK for applications requiring the extended upper temperature limit.

Q: What is the difference between CMF5520K000BEEB and CMF5520K000BEEK? A: Both parts have identical electrical specifications (20 kOhms ±0.1%, 0.5W, ±25ppm/°C). The difference is packaging format: CMF5520K000BEEB is supplied in Cut Tape, while CMF5520K000BEEK is supplied in Bulk.
