Key Parameters

Substitute Part Grouping Explanation

Substitution for the PRNF14FTD402R is determined by the following criteria:

Direct Equivalent (Same Packaging): RNF14FTD402R maintains identical electrical specifications (402 Ohms ±1%, 0.25W, Metal Film, ±100ppm/°C) with the only difference being packaging format (Cut Tape vs. Tape & Reel). This part is functionally interchangeable for circuit applications.

Upgraded Substitutes (Higher Power Rating): CMF55402R00FHEB and CPF1402R00FEEE6 provide increased power dissipation capability (0.5W and 1W respectively) while maintaining the core electrical parameters (402 Ohms ±1%, Metal Film composition). These upgrades are applicable in circuits where the original 0.25W rating may be marginal or where thermal headroom is required. Both upgrades maintain axial package compatibility and ROHS3 compliance.

Key Parameters for Substitution:

• Resistance value: 402 Ohms (fixed)
• Tolerance: ±1% (fixed)
• Composition: Metal Film (fixed)
• Package: Axial (fixed)
• Compliance: ROHS3 (maintained across all substitutes)

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD402R is the direct equivalent substitute, differing only in packaging format (Cut Tape instead of Tape & Reel). Selection of this part is appropriate when tape format is acceptable for assembly processes and identical electrical performance is required.

CMF55402R00FHEB provides a 0.5W power upgrade with improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C) and extended operating temperature range to 175°C. This upgrade is suitable for applications requiring enhanced thermal margin or operation at elevated ambient temperatures while maintaining ROHS3 compliance.

CPF1402R00FEEE6 provides maximum power rating at 1W with the lowest temperature coefficient (±25ppm/°C) and widest operating temperature range (-65°C ~ 230°C). This upgrade is applicable in high-power dissipation circuits or extreme temperature environments. All three substitute parts maintain Active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD402R replace PRNF14FTD402R directly? A: Yes. RNF14FTD402R is electrically and mechanically identical to PRNF14FTD402R. The only difference is packaging format (Cut Tape vs. Tape & Reel). Both are 402 Ohm ±1% metal film resistors rated at 0.25W with identical temperature coefficients and operating ranges.

Q: When should CMF55402R00FHEB be used instead of the original part? A: CMF55402R00FHEB should be selected when the circuit requires higher power dissipation capability (0.5W vs. 0.25W), improved temperature stability (±50ppm/°C vs. ±100ppm/°C), or operation at temperatures up to 175°C. The 402 Ohm resistance and ±1% tolerance remain identical.

Q: Is CPF1402R00FEEE6 compatible with the original circuit design? A: CPF1402R00FEEE6 is electrically compatible as a 402 Ohm ±1% metal film resistor in axial package. It provides upgraded specifications: 1W power rating, ±25ppm/°C temperature coefficient, and -65°C ~ 230°C operating range. Physical dimensions are similar (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L), making it suitable for most PCB layouts.

Q: Are all substitute parts ROHS3 compliant? A: Yes. PRNF14FTD402R, RNF14FTD402R, CMF55402R00FHEB, and CPF1402R00FEEE6 are all ROHS3 compliant with Active product status.

Q: What is the difference between packaging formats (Tape & Reel vs. Cut Tape)? A: Tape & Reel (TR) packaging is supplied on continuous tape wound on reels for automated assembly. Cut Tape (CT) packaging is supplied as individual tape segments. Both formats contain identical components; selection depends on assembly equipment and volume requirements.

Q: Can these parts be used interchangeably in high-temperature applications? A: PRNF14FTD402R and RNF14FTD402R are rated to 155°C. CMF55402R00FHEB extends to 175°C, and CPF1402R00FEEE6 extends to 230°C. For applications exceeding 155°C, CMF55402R00FHEB or CPF1402R00FEEE6 must be selected.
