RNF14FAD47K0 Equivalent & Substitute Parts

Part Overview

The RNF14FAD47K0 is a 47 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 characteristics suitable for industrial and commercial applications. The part maintains Active product status with ROHS3 compliance and REACH unaffected certification.

Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and regulatory compliance are maintained across packaging formats and series variants within the RNF product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FAD47K0 is determined by strict equivalence across the following parameters:

• Resistance value: 47 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package type: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Substitute parts are grouped into two categories based on packaging format and series designation:

Category 1: Direct Packaging Variant – RNF14FTD47K0 maintains identical electrical and mechanical specifications with alternative tape packaging (Cut Tape vs. Tape & Box).

Category 2: Series Variant with Dimensional Difference – RNMF14FAD47K0 represents the RNMF (Mini) series variant with reduced physical dimensions (0.070" Dia x 0.130" L vs. 0.093" Dia x 0.250" L) while maintaining all electrical parameters and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with identical electrical specifications and full regulatory compliance (ROHS3 Compliant, REACH Unaffected). Selection between RNF14FAD47K0 and RNF14FTD47K0 is determined by packaging requirements: Tape & Box format versus Cut Tape format. Both maintain standard RNF series dimensions.

Selection of RNMF14FAD47K0 is appropriate when space constraints require the miniaturized axial package (RNMF series). The reduced physical dimensions (0.070" Dia x 0.130" L) provide equivalent electrical performance within a smaller footprint. PCB layout and lead spacing compatibility must be verified for this variant.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD47K0 replace RNF14FAD47K0 in production?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: RNF14FAD47K0 is supplied in Tape & Box (TB) format, while RNF14FTD47K0 is supplied in Cut Tape (CT) format. Selection depends on assembly line requirements and inventory management practices.

Q: What is the primary difference between RNF14FAD47K0 and RNMF14FAD47K0?

A: The RNMF14FAD47K0 is the miniaturized variant of the RNF series. All electrical parameters are identical (47 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C). The physical dimensions are reduced from 0.093" Dia x 0.250" L to 0.070" Dia x 0.130" L. This substitution is valid only when PCB layout accommodates the smaller package footprint.

Q: Are all three parts ROHS3 compliant?

A: Yes. RNF14FAD47K0, RNF14FTD47K0, and RNMF14FAD47K0 are all ROHS3 Compliant with REACH Unaffected status.

Q: Can RNMF14FAD47K0 be used in existing designs without modification?

A: RNMF14FAD47K0 substitution requires verification of PCB layout compatibility due to reduced physical dimensions. Lead spacing and hole positioning must accommodate the miniaturized axial package before implementation.

Q: What determines substitution eligibility for 47 kOhms metal film resistors?

A: Substitution is valid when resistance value (47 kOhms), tolerance (±1%), power rating (0.25W), composition (Metal Film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH) remain constant. Package type (Axial) and physical dimensions must be compatible with circuit design requirements.
