RNF14FAD5K62 Equivalent & Substitute Parts

Part Overview

The RNF14FAD5K62 is a 5.62 kOhms ±1% metal film through-hole resistor rated at 0.25W (1/4W) in axial package configuration. Manufactured by Stackpole Electronics Inc, this component features flame retardant coating and safety-rated construction suitable for general-purpose electronic applications. The part maintains Active product status with ROHS3 compliance and operates across the -55°C to 155°C temperature range. Substitute parts are identified to address packaging availability, inventory requirements, or enhanced performance specifications while maintaining core electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on allowed electrical and mechanical parameters:

Direct Equivalent (Same Electrical Specifications): RNF14FTD5K62 maintains identical electrical characteristics to the main part: 5.62 kOhms ±1% tolerance, 0.25W power rating, metal film composition, and ±100ppm/°C temperature coefficient. The only difference is packaging format (Cut Tape versus Tape & Box), which does not affect electrical performance or mechanical compatibility in axial configuration.

Upgraded Substitute (Enhanced Performance Parameters): CMF555K6200FHEB and CMF555K6200FHEK are manufactured by Vishay Dale and provide upgraded specifications within allowable substitution parameters. Both maintain the core electrical value (5.62 kOhms ±1%) and axial package type. Key differences include increased power rating (0.5W versus 0.25W), improved temperature coefficient (±50ppm/°C versus ±100ppm/°C), extended operating temperature range (-55°C to 175°C versus -55°C to 155°C), and additional moisture-resistant features. These upgrades represent performance enhancements suitable for applications requiring higher power dissipation or tighter tolerance stability.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD5K62 Selection Criteria: Select this direct equivalent when packaging format flexibility is required. This part maintains identical electrical performance and thermal characteristics as the main part while offering Cut Tape packaging. Both parts carry Active product status and ROHS3 compliance. Mechanical compatibility is preserved through identical axial package dimensions (0.093" Dia x 0.250" L).

CMF555K6200FHEB / CMF555K6200FHEK Selection Criteria: These Vishay Dale upgrades are suitable for applications requiring enhanced thermal stability or extended operating temperature ranges. The reduced temperature coefficient (±50ppm/°C) provides improved frequency stability in precision circuits. The increased 0.5W power rating accommodates higher dissipation requirements without component derating. Both maintain ROHS3 compliance and Active product status. CMF555K6200FHEB is available in Cut Tape packaging, while CMF555K6200FHEK is supplied in Bulk format. Selection between these two depends on procurement and assembly requirements rather than electrical performance.

All substitute parts maintain mechanical compatibility through axial package configuration and preserve the core electrical specification of 5.62 kOhms ±1% tolerance.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD5K62 be used as a direct replacement for RNF14FAD5K62? A: Yes. Both parts share identical electrical specifications: 5.62 kOhms ±1% tolerance, 0.25W power rating, metal film composition, and ±100ppm/°C temperature coefficient. The difference is packaging format (Cut Tape versus Tape & Box), which does not affect electrical performance or axial mechanical compatibility.

Q: What are the advantages of using CMF555K6200FHEB or CMF555K6200FHEK? A: These upgrades provide three performance enhancements: doubled power rating (0.5W versus 0.25W) for higher dissipation applications, improved temperature coefficient (±50ppm/°C versus ±100ppm/°C) for better frequency stability, and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). All maintain the 5.62 kOhms ±1% core specification.

Q: Are there mechanical compatibility concerns when substituting these parts? A: No. All substitute parts use identical axial package configuration with compatible lead spacing and diameter. Physical board layout and footprint requirements remain unchanged.

Q: What is the difference between CMF555K6200FHEB and CMF555K6200FHEK? A: Both parts are electrically and mechanically identical. The difference is packaging format: CMF555K6200FHEB is supplied in Cut Tape, while CMF555K6200FHEK is supplied in Bulk. Selection depends on assembly process requirements and inventory management preferences.

Q: Do all substitute parts maintain RoHS compliance? A: Yes. The main part RNF14FAD5K62 and all substitute parts (RNF14FTD5K62, CMF555K6200FHEB, CMF555K6200FHEK) are ROHS3 compliant.

Q: Can upgraded parts be used in applications originally designed for the RNF14FAD5K62? A: Yes. The CMF555K6200FHEB and CMF555K6200FHEK upgrades are backward compatible. Enhanced specifications (higher power rating, better temperature coefficient, extended temperature range) do not create incompatibility with designs specified for the original part.
