RNF14FAD4K22 Equivalent & Substitute Parts

Part Overview

The RNF14FAD4K22 is a 4.22 kOhms ±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 RNF series and maintains active product status. Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, composition) and mechanical compatibility (axial package, lead configuration) while accommodating variations in packaging format and physical dimensions within the RNMF mini series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FAD4K22 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 4.22 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)

Mechanical Compatibility Requirements:

• Package configuration: Axial leads (exact match required)
• Number of terminations: 2 (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match or better required)

Regulatory & Compliance Requirements:

• RoHS3 Compliant (exact match required)
• REACH Unaffected (exact match required)

Packaging format (Tape & Box, Cut Tape, Tape & Reel) and physical dimensions may vary within the RNF and RNMF series while maintaining functional equivalence. Temperature coefficient variations are permitted when all other parameters match.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD4K22 (Direct Substitute): Functionally identical to the main part with matching electrical and mechanical specifications. Differs only in packaging format (Cut Tape vs. Tape & Box). Suitable for direct replacement in production environments where cut tape packaging is acceptable. Active product status and full compliance certifications maintained.

RNF14FTC4K22 (Upgrade Option): Meets all electrical and mechanical requirements with improved temperature coefficient performance (±50ppm/°C vs. ±100ppm/°C). Provides enhanced stability in temperature-sensitive applications. Cut Tape packaging format. Active product status with full compliance certifications.

RNMF14FTD4K22 (MFR Recommended): Manufacturer-recommended alternative from the RNMF mini series. Maintains all electrical specifications and compliance requirements. Physical dimensions are reduced (0.070" Dia x 0.130" L vs. 0.093" Dia x 0.250" L), enabling space-constrained PCB layouts. Tape & Reel packaging format. Active product status with full compliance certifications. Verify PCB footprint compatibility before selection.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD4K22 replace RNF14FAD4K22 directly? A: Yes. Both parts share identical electrical specifications (4.22 kOhms ±1%, 0.25W, metal film composition) and mechanical configuration (axial package, 2 terminations). The difference is packaging format only (Cut Tape vs. Tape & Box). Direct substitution is valid.

Q: What is the advantage of RNF14FTC4K22? A: RNF14FTC4K22 provides improved temperature coefficient stability at ±50ppm/°C compared to ±100ppm/°C in the main part. All other electrical and mechanical parameters remain identical. Selection depends on application temperature stability requirements.

Q: Is RNMF14FTD4K22 compatible with existing PCB designs? A: RNMF14FTD4K22 maintains the same electrical specifications and axial lead configuration but has reduced physical dimensions (0.070" Dia x 0.130" L vs. 0.093" Dia x 0.250" L). PCB footprint compatibility must be verified before implementation. The mini form factor enables space optimization in compact designs.

Q: Are all substitute parts RoHS3 and REACH compliant? A: Yes. All listed substitute parts (RNF14FTD4K22, RNF14FTC4K22, RNMF14FTD4K22) maintain ROHS3 Compliant and REACH Unaffected status, matching the main part's regulatory compliance.

Q: What packaging formats are available? A: RNF14FAD4K22 is supplied in Tape & Box (TB) format. Substitutes are available in Cut Tape (CT) for RNF14FTD4K22 and RNF14FTC4K22, and Tape & Reel (TR) for RNMF14FTD4K22. Selection depends on production volume and assembly process requirements.

Q: Can I use these parts interchangeably in the same circuit? A: Yes, provided PCB footprint and lead spacing accommodate the physical dimensions. RNF series parts (standard and mini) share identical electrical performance and axial lead configuration. Verify mechanical fit for RNMF14FTD4K22 due to reduced size.
