Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Substitutes maintain identical electrical specifications (5.23 kOhms, ±1% tolerance, 0.25W power rating, metal film composition) and axial package configuration. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility.

Manufacturer-Recommended Substitutes (RNMF series) provide equivalent electrical performance with reduced physical dimensions. The RNMF14FTD5K23 maintains all core electrical parameters while offering a smaller axial footprint (0.070" Dia x 0.130" L versus 0.093" Dia x 0.250" L).

Upgrade Substitutes provide enhanced specifications within the same resistance and tolerance class. The CMF555K2300FHEB increases power rating to 0.5W (1/2W) and improves temperature coefficient to ±50ppm/°C, with extended operating temperature to 175°C.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD5K23 is a direct substitute with identical electrical and mechanical specifications. Selection is appropriate when packaging format change from Tape & Reel to Cut Tape is acceptable for procurement and assembly workflows.

RNMF14FTD5K23 is suitable for applications where board space is constrained. The reduced axial dimensions (0.070" Dia x 0.130" L) provide a 48% reduction in length and 25% reduction in diameter while maintaining all electrical parameters. This component is recommended for compact PCB layouts where the smaller footprint provides design advantage.

CMF555K2300FHEB is appropriate for applications requiring enhanced thermal performance or higher power dissipation margins. The doubled power rating (0.5W versus 0.25W) and improved temperature coefficient (±50ppm/°C versus ±100ppm/°C) support operation in higher ambient temperature environments or circuits with elevated power requirements. Extended operating temperature range to 175°C accommodates demanding thermal conditions.

All substitute parts maintain ROHS3 compliance and Active product status, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD5K23 replace PRNF14FTD5K23 in all applications? A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format (Cut Tape versus Tape & Reel). Selection depends on procurement and assembly requirements.

Q: What is the primary advantage of RNMF14FTD5K23? A: The RNMF series provides a smaller axial footprint (0.070" Dia x 0.130" L) compared to the standard RNF series (0.093" Dia x 0.250" L). This is beneficial for space-constrained PCB designs while maintaining identical electrical specifications.

Q: When should CMF555K2300FHEB be selected over the Stackpole alternatives? A: The CMF555K2300FHEB offers doubled power rating (0.5W) and improved temperature coefficient (±50ppm/°C). Select this part when circuits require higher power dissipation capability or operation in elevated temperature environments up to 175°C.

Q: Are all substitute parts ROHS3 compliant? A: Yes. PRNF14FTD5K23, RNF14FTD5K23, RNMF14FTD5K23, and CMF555K2300FHEB are all ROHS3 Compliant.

Q: Does the axial package configuration remain consistent across all substitutes? A: Yes. All listed parts use axial through-hole configuration, ensuring compatibility with standard PCB footprints designed for axial resistors.

Q: What is the tolerance specification across all parts? A: All parts maintain ±1% tolerance, ensuring consistent circuit performance and accuracy across substitution options.
