RNF14FTC250R Equivalent & Substitute Parts

Part Overview

The RNF14FTC250R is a 250 Ohms ±1% metal film through-hole resistor rated at 0.25W (1/4W) with axial leads and flame retardant coating. Manufactured by Stackpole Electronics Inc, this component is part of the active RNF series and is ROHS3 compliant. Alternative parts may be required due to inventory constraints, design upgrades for improved tolerance specifications, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC250R is determined by the following critical parameters:

• Resistance Value: Must be 250 Ohms
• Power Rating: Must be 0.25W (1/4W)
• Package Type: Must be Axial
• Composition: Must be Metal Film
• Temperature Coefficient: Must be ±50ppm/°C
• Operating Temperature Range: Must be -55°C to 155°C
• Compliance: Must maintain ROHS3 compliance

The RNF14BTC250R qualifies as a direct substitute because it matches all critical electrical and mechanical parameters. The primary difference is an improved tolerance specification (±0.1% versus ±1%), which represents an upgrade path rather than a functional limitation.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC250R and RNF14BTC250R are active products from Stackpole Electronics Inc with full ROHS3 compliance. The RNF14BTC250R provides improved tolerance performance (±0.1% versus ±1%) while maintaining identical electrical and mechanical specifications. Selection between these parts should be based on application tolerance requirements and inventory availability. Both components are suitable for direct substitution in circuits where the specified parameters are required.

Frequently Asked Questions (FAQ)

Q: Can RNF14BTC250R replace RNF14FTC250R in existing designs?

A: Yes. The RNF14BTC250R is electrically and mechanically compatible with the RNF14FTC250R. Both components share identical resistance values, power ratings, package types, temperature coefficients, and operating temperature ranges. The primary difference is improved tolerance specification in the substitute part.

Q: What is the significance of the tolerance difference between ±1% and ±0.1%?

A: Tolerance defines the maximum deviation from the nominal resistance value. The RNF14BTC250R with ±0.1% tolerance provides tighter resistance control compared to the RNF14FTC250R with ±1% tolerance. Applications requiring precise resistance values benefit from the improved tolerance specification.

Q: Are both parts available in the same packaging format?

A: Yes. Both the RNF14FTC250R and RNF14BTC250R are supplied in Tape & Reel (TR) packaging with identical axial lead configuration and physical dimensions (0.093" Dia x 0.250" L / 2.35mm x 6.35mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. They meet identical regulatory and environmental requirements.
