RNF14FAD182K Equivalent & Substitute Parts

Part Overview

The RNF14FAD182K is a 182 kOhms ±1% 0.25W (1/4W) through-hole resistor manufactured by Stackpole Electronics Inc. This axial metal film resistor features flame retardant coating and safety construction, designed for general-purpose electronic applications requiring precision resistance values. The part is currently active in production with ROHS3 compliance and is available in Tape & Box packaging. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, packaging format preferences, or performance upgrades.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD182K (Direct Substitute): This part maintains identical electrical and mechanical specifications to the RNF14FAD182K. Selection is appropriate when packaging format change from Tape & Box to Cut Tape is acceptable. Both parts are manufactured by Stackpole Electronics Inc and carry active product status with ROHS3 compliance. Inventory availability is higher for the RNF14FTD182K variant.

CMF55182K00FHEB (Upgrade Substitute): This Vishay Dale part provides enhanced performance characteristics while maintaining the core 182 kOhms ±1% resistance specification. The upgrade offers increased power dissipation capacity (0.5W vs. 0.25W), improved temperature coefficient stability (±50ppm/°C vs. ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). Additional moisture resistance feature is included. Selection is appropriate for applications requiring higher thermal margin or improved long-term stability. Both parts maintain ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD182K be used as a direct replacement for RNF14FAD182K? A: Yes. Both parts share identical electrical specifications (182 kOhms ±1% 0.25W metal film axial resistor) and mechanical dimensions. The primary difference is packaging format: RNF14FAD182K is supplied in Tape & Box format, while RNF14FTD182K is supplied in Cut Tape format. Electrical performance and board-level compatibility are equivalent.

Q: What are the advantages of using CMF55182K00FHEB over the original RNF14FAD182K? A: The CMF55182K00FHEB provides three performance enhancements: (1) doubled power rating (0.5W vs. 0.25W) for improved thermal headroom, (2) superior temperature coefficient (±50ppm/°C vs. ±100ppm/°C) for better long-term stability, and (3) extended operating temperature range to 175°C. Moisture resistance is an additional feature. These upgrades are beneficial in high-temperature or high-reliability applications.

Q: Are all three parts mechanically compatible with the same PCB footprint? A: Yes. All three parts are axial through-hole resistors with identical lead spacing and compatible physical dimensions. PCB footprints designed for the RNF14FAD182K will accommodate both substitute parts without modification.

Q: Do all parts meet the same compliance standards? A: Yes. RNF14FAD182K, RNF14FTD182K, and CMF55182K00FHEB are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All parts carry active product status.

Q: What is the difference between Tape & Box and Cut Tape packaging? A: Tape & Box packaging combines tape-wound components with bulk box storage, suitable for mixed-volume orders. Cut Tape packaging provides individual component strips, optimized for automated assembly and higher-volume production. Electrical specifications remain identical regardless of packaging format.
