RNF14CTD100K Equivalent & Substitute Parts

Part Overview

The RNF14CTD100K is a 100 kOhms ±0.25% metal film through-hole resistor rated at 0.25W (1/4W) in axial package configuration, manufactured by Stackpole Electronics Inc. The component features flame retardant coating and safety-grade construction with operating temperature range of -55°C to 155°C. This part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent resistance values, power ratings, and mechanical compatibility can be maintained while meeting or exceeding the original specifications.

Parameter Comparison

Engineering Selection Recommendations

RNF14BTE100K (Stackpole Electronics Inc): This substitute provides tighter tolerance (±0.1% versus ±0.25%) and superior temperature coefficient (±25ppm/°C versus ±100ppm/°C) while maintaining identical power rating, operating temperature range, and physical dimensions. Both parts are from the same manufacturer within the RNF series. Packaging differs from Tape & Reel to Cut Tape format. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are maintained.

CPF1100K00BHEE6 (Vishay Dale): This substitute offers increased power rating (1W versus 0.25W), tighter tolerance (±0.1%), and extended operating temperature range (-65°C ~ 230°C versus -55°C ~ 155°C). Physical dimensions are slightly smaller. Temperature coefficient is ±50ppm/°C. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are maintained. The higher power rating provides additional thermal margin in applications.

Frequently Asked Questions (FAQ)

Q: Can RNF14BTE100K be used as a direct replacement for RNF14CTD100K?

A: Yes. Both parts share identical resistance, power rating, operating temperature range, and physical dimensions. RNF14BTE100K provides improved tolerance and temperature coefficient specifications. The packaging format differs (Cut Tape versus Tape & Reel), which does not affect electrical or mechanical compatibility in circuit applications.

Q: What are the dimensional differences between CPF1100K00BHEE6 and the original part?

A: CPF1100K00BHEE6 has slightly smaller dimensions (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L). These differences are within typical PCB layout tolerances for axial through-hole components and do not prevent board-level substitution.

Q: Is CPF1100K00BHEE6 suitable for applications requiring 0.25W power dissipation?

A: Yes. CPF1100K00BHEE6 is rated at 1W, which exceeds the 0.25W requirement of the original specification. The higher power rating provides additional thermal headroom and does not create compatibility issues in circuits designed for 0.25W components.

Q: How do tolerance specifications affect substitution?

A: RNF14CTD100K specifies ±0.25% tolerance. Both substitute parts offer ±0.1% tolerance, which is tighter and therefore acceptable. Tighter tolerance ensures more precise resistance values and improved circuit performance in precision applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. RNF14CTD100K, RNF14BTE100K, and CPF1100K00BHEE6 are all ROHS3 compliant with REACH Unaffected status and EAR99 export classification.

Q: What is the temperature coefficient significance in selecting a substitute?

A: Temperature coefficient indicates resistance change per degree Celsius. RNF14BTE100K (±25ppm/°C) and CPF1100K00BHEE6 (±50ppm/°C) both provide better temperature stability than the original RNF14CTD100K (±100ppm/°C), resulting in more stable circuit performance across the operating temperature range.
