Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FAD23K2 are classified based on the following critical parameters that determine functional equivalence:

Direct Equivalent Criteria:

• Resistance value: 23.2 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Package: Axial
• Compliance: ROHS3 Compliant, REACH Unaffected

Packaging Variant (Direct Equivalent): RNF14FTD23K2 maintains identical electrical specifications and physical dimensions as the main part. The substitution is based on packaging format difference (Cut Tape vs. Tape & Box), with no impact on component performance or circuit compatibility.

Upgraded Substitute (Performance Enhancement): CMF5523K200FHEB is classified as an upgrade substitute due to increased power rating (0.5W vs. 0.25W) and improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C). All other critical parameters remain equivalent. This part is suitable for applications requiring higher power dissipation capability or improved thermal stability.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD23K2 Selection: Select this part when packaging format flexibility is required. Identical electrical and thermal performance to the main part with equivalent compliance certifications. Suitable for high-volume production environments utilizing cut tape automation.

CMF5523K200FHEB Selection: Select this part for applications requiring enhanced power dissipation (0.5W rating) or improved frequency stability (±50ppm/°C temperature coefficient). Extended operating temperature range (-55°C ~ 175°C) provides additional thermal margin. Moisture-resistant construction offers enhanced environmental protection. All parts maintain ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD23K2 be used as a direct replacement for RNF14FAD23K2? A: Yes. Both parts are identical in electrical specifications, physical dimensions, and performance characteristics. The difference is packaging format only (Cut Tape vs. Tape & Box), which does not affect circuit functionality or component reliability.

Q: Is CMF5523K200FHEB compatible with circuits designed for RNF14FAD23K2? A: Yes, with design considerations. The CMF5523K200FHEB maintains the same resistance value, tolerance, and axial package configuration. The increased power rating (0.5W vs. 0.25W) and improved temperature coefficient (±50ppm/°C) make it suitable for the same applications. Physical dimensions are comparable (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L), allowing board-level compatibility.

Q: What are the key parameters that determine substitution eligibility? A: Critical parameters are resistance value (23.2 kOhms), tolerance (±1%), composition (metal film), package type (axial), and compliance certifications (ROHS3, REACH). Power rating and temperature coefficient may vary based on application requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RNF14FTD23K2 and CMF5523K200FHEB are both ROHS3 compliant and REACH unaffected, matching the compliance profile of the main part.

Q: What is the difference between Tape & Box and Cut Tape packaging? A: Tape & Box (TB) packaging includes a protective box for component storage and manual handling. Cut Tape (CT) packaging is supplied on continuous tape for automated pick-and-place assembly. Both formats contain identical components with no electrical or performance differences.
