RNF14GAD200R Equivalent & Substitute Parts

Part Overview

The RNF14GAD200R is a 200 Ohm ±2% metal film axial through-hole resistor rated at 0.25W (1/4W) manufactured by Stackpole Electronics Inc. This component is actively produced and widely used in general-purpose electronic circuits requiring precision resistive elements with flame retardant coating and safety features. Substitute parts may be required due to inventory constraints, design upgrades for improved tolerance specifications, or higher power rating requirements in circuit redesigns.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14GAD200R is determined by the following criteria:

Core Compatibility Requirements:

• Resistance value: 200 Ohms (exact match required)
• Package type: Axial (mechanical and electrical compatibility)
• Composition: Metal Film (performance characteristics)
• Compliance: ROHS3 Compliant, REACH Unaffected

Allowable Parameter Variations:

• Tolerance: May be equal to or tighter (lower) than ±2%
• Power rating: May be equal to or higher than 0.25W
• Temperature coefficient: May be equal to or lower (better stability)
• Operating temperature range: May be equal to or wider than -55°C to 155°C

All three substitute parts meet these criteria and maintain electrical and mechanical compatibility with the original RNF14GAD200R specification.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD200R (Stackpole Electronics Inc): Direct upgrade within the same manufacturer series. Identical power rating and operating temperature range. Improved tolerance specification (±1% vs ±2%) provides tighter resistance accuracy. Same packaging and physical dimensions ensure direct board-level compatibility. Recommended for designs requiring enhanced tolerance performance without power rating changes.

CMF55200R00BHEB (Vishay Dale): Highest precision substitute with ±0.1% tolerance and 0.5W power rating. Superior temperature coefficient (±50ppm/°C vs ±100ppm/°C) and extended operating temperature range (-55°C to 175°C). Slightly smaller physical dimensions require verification of PCB layout compatibility. Recommended for precision analog circuits and applications requiring enhanced thermal performance.

CMF55200R00FHEB (Vishay Dale): Balanced upgrade combining ±1% tolerance with 0.5W power rating. Improved temperature coefficient and extended operating range match CMF55200R00BHEB specifications. Suitable for applications where moderate tolerance improvement and increased power dissipation capability are required without the cost of ±0.1% precision.

All substitute parts maintain ROHS3 compliance and active product status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD200R be used as a direct replacement for RNF14GAD200R?

A: Yes. Both parts are manufactured by Stackpole Electronics Inc, share identical physical dimensions (0.093" Dia x 0.250" L), power rating (0.25W), and operating temperature range (-55°C to 155°C). The RNF14FTD200R provides improved tolerance (±1% vs ±2%), making it a direct upgrade with no board-level modifications required.

Q: What are the physical dimension differences between Stackpole and Vishay Dale axial resistors?

A: Stackpole RNF series measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm). Vishay Dale CMF55 series measures 0.090" Dia x 0.240" L (2.29mm x 6.10mm). The CMF55 components are slightly smaller. PCB layout verification is required before substitution to confirm adequate clearance and component spacing.

Q: Which substitute provides the best temperature stability?

A: Both Vishay Dale parts (CMF55200R00BHEB and CMF55200R00FHEB) offer superior temperature coefficient specifications (±50ppm/°C vs ±100ppm/°C for Stackpole parts). CMF55200R00BHEB additionally provides the tightest tolerance (±0.1%) for maximum stability across temperature variations.

Q: Can I use a 0.5W rated resistor in place of a 0.25W rated resistor?

A: Yes. A higher power rating provides greater thermal margin and is electrically compatible. The circuit will operate safely with CMF55200R00BHEB or CMF55200R00FHEB (both 0.5W rated) in applications originally designed for 0.25W resistors. Physical dimensions must be verified for PCB fit.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RNF14FTD200R, CMF55200R00BHEB, and CMF55200R00FHEB are all ROHS3 Compliant and REACH Unaffected, maintaining regulatory compliance with the original RNF14GAD200R specification.
