RNF14FAD562K Equivalent & Substitute Parts

Part Overview

The RNF14FAD562K is a 562 kOhms ±1% 0.25W (1/4W) through-hole resistor manufactured by Stackpole Electronics Inc. This axial metal film resistor features flame retardant coating and safety characteristics, designed for applications requiring precision resistance values in compact form factors. The part is currently active in production with ROHS3 compliance and is available in Tape & Box packaging. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement or functional upgrade in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FAD562K are identified based on the following allowable parameters:

Direct Substitutes (Same Electrical Specifications):

• Resistance value: 562 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial
• Operating temperature range: -55°C ~ 155°C minimum
• Compliance: ROHS3 Compliant

Upgrade Substitutes (Enhanced Specifications):

• Same resistance and tolerance as above
• Higher power rating (0.5W / 1/2W) with maintained or improved temperature coefficient
• Same axial package compatibility
• Enhanced operating temperature range or improved thermal characteristics
• ROHS3 Compliant

The RNF14FTD562K qualifies as a direct substitute with identical electrical and mechanical specifications, differing only in packaging format (Cut Tape vs. Tape & Box). The CMF55562K00FHEB qualifies as an upgrade substitute, offering higher power dissipation capability and improved temperature coefficient while maintaining the same resistance, tolerance, and axial form factor.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD562K Selection: Select the RNF14FTD562K when packaging format change from Tape & Box to Cut Tape is acceptable. This part maintains identical electrical performance and mechanical compatibility with the RNF14FAD562K. Both parts are manufactured by Stackpole Electronics Inc and carry ROHS3 compliance. Inventory availability is higher for the RNF14FTD562K (11,749 pcs vs. 928 pcs).

CMF55562K00FHEB Selection: Select the CMF55562K00FHEB when circuit design permits higher power dissipation capability or when improved temperature stability is required. This upgrade substitute offers 0.5W power rating versus 0.25W, extended operating temperature range to 175°C, and superior temperature coefficient (±50ppm/°C vs. ±100ppm/°C). Physical dimensions are slightly smaller, maintaining axial package compatibility. ROHS3 compliance is maintained. This part is suitable for applications with higher thermal stress or stricter tolerance requirements.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD562K replace RNF14FAD562K in all applications? A: Yes. The RNF14FTD562K is electrically and mechanically identical to the RNF14FAD562K. The only difference is packaging format (Cut Tape vs. Tape & Box). Both parts have identical resistance (562 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C).

Q: When should CMF55562K00FHEB be used instead of the original part? A: The CMF55562K00FHEB should be selected when the circuit operates in higher temperature environments (up to 175°C vs. 155°C), when power dissipation exceeds 0.25W, or when tighter tolerance stability is required due to its superior temperature coefficient (±50ppm/°C). The upgrade maintains the same 562 kOhms resistance and ±1% tolerance.

Q: Are there physical compatibility concerns with CMF55562K00FHEB? A: The CMF55562K00FHEB has slightly smaller dimensions (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L). Both are axial package resistors and are compatible with standard through-hole PCB layouts. The smaller size may provide additional board space benefits.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All three parts (RNF14FAD562K, RNF14FTD562K, and CMF55562K00FHEB) are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Q: What is the difference between Tape & Box and Cut Tape packaging? A: Tape & Box packaging includes a protective box for storage and handling, suitable for smaller quantity orders or manual assembly. Cut Tape packaging is supplied on continuous tape, optimized for automated pick-and-place assembly equipment. Both formats contain the same component.
