Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC470R is determined by the following critical parameters:

• Resistance value: 470 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Regulatory compliance: RoHS3 and REACH status (exact match required)

The RNMF14FTC470R qualifies as a direct substitute based on identical electrical specifications and regulatory compliance. The primary distinction is the packaging format (Cut Tape versus Tape & Reel) and physical dimensions, which do not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC470R and RNMF14FTC470R are Active products with identical electrical performance and full regulatory compliance. Selection between these parts is based on application-specific requirements:

The RNF14FTC470R in Tape & Reel packaging is suitable for high-volume automated assembly operations requiring continuous reel feeding. The RNMF14FTC470R in Cut Tape format accommodates lower-volume production runs, manual assembly processes, or applications where smaller physical dimensions are advantageous. Both parts satisfy identical electrical and thermal specifications, making them functionally interchangeable in circuit design. The choice between standard and mini form factors depends on PCB layout constraints and assembly methodology rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC470R replace RNF14FTC470R in existing designs?

A: Yes. Both parts share identical electrical specifications including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. The primary differences are packaging format and physical dimensions. Circuit performance remains unchanged.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous reels for automated pick-and-place assembly systems. Cut Tape packaging provides individual strips of components for manual assembly or lower-volume production. Both formats contain identical components.

Q: Are the physical dimension differences significant?

A: The RNMF14FTC470R (mini version) has smaller dimensions: 0.070" diameter x 0.130" length compared to the RNF14FTC470R at 0.093" diameter x 0.250" length. This affects PCB layout and assembly handling but does not impact electrical performance. Selection depends on available board space and assembly equipment compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RNF14FTC470R and RNMF14FTC470R are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards for industrial and commercial applications.

Q: Which part should be selected for new designs?

A: Selection is based on manufacturing process requirements. For automated high-volume assembly, the Tape & Reel format (RNF14FTC470R) is standard. For manual assembly or space-constrained designs, the Cut Tape mini version (RNMF14FTC470R) may be preferred. Both are equally suitable from an electrical standpoint.
