Substitute Part Grouping Explanation

Substitute parts for the PRNF14FTD23K2 are classified into two categories based on electrical and mechanical parameter alignment:

Direct Equivalents maintain identical electrical specifications (23.2 kOhms, ±1% tolerance, 0.25W power rating, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical form factor (axial configuration, 0.093" Dia x 0.250" L). These parts differ only in packaging format (Tape & Reel, Tape & Box, or Cut Tape) and inventory availability. Direct equivalents include RNF14FAD23K2 and RNF14FTD23K2.

Upgrade Substitute (CMF5523K200FHEB) provides enhanced electrical performance with increased power rating (0.5W vs 0.25W), improved temperature coefficient (±50ppm/°C vs ±100ppm/°C), and extended upper operating temperature (175°C vs 155°C). The resistance value (23.2 kOhms) and tolerance (±1%) remain identical. Mechanical dimensions are comparable (0.090" Dia x 0.240" L vs 0.093" Dia x 0.250" L). This substitute is suitable for applications requiring higher power dissipation or stricter temperature stability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution: RNF14FAD23K2 and RNF14FTD23K2 are interchangeable with PRNF14FTD23K2 when electrical performance and mechanical fit are the primary criteria. Selection between these direct equivalents depends on packaging requirements: Tape & Reel for automated assembly processes, Tape & Box for manual handling, or Cut Tape for mixed-volume applications. All three maintain identical electrical characteristics and comply with ROHS3 and REACH requirements.

For Upgraded Performance: CMF5523K200FHEB is suitable when applications require higher power dissipation capability (0.5W vs 0.25W), improved temperature stability (±50ppm/°C vs ±100ppm/°C), or operation at elevated temperatures up to 175°C. The Vishay Dale CMF series adds moisture resistance to the feature set. Mechanical dimensions are slightly smaller, which may benefit space-constrained layouts. This upgrade maintains ROHS3 compliance and REACH unaffected status.

All substitute parts are active products with current inventory availability and meet the same regulatory and compliance standards as the primary part.

Frequently Asked Questions (FAQ)

Q: Can RNF14FAD23K2 replace PRNF14FTD23K2 in production? A: Yes. Both parts have identical electrical specifications (23.2 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical form factor. The difference is packaging format: RNF14FAD23K2 is supplied in Tape & Box while PRNF14FTD23K2 is in Tape & Reel. Selection depends on assembly process requirements.

Q: What is the difference between RNF14FTD23K2 and PRNF14FTD23K2? A: These parts are electrically and mechanically identical. Both are Stackpole RNF series 23.2 kOhms ±1% 0.25W axial resistors. The primary difference is packaging: RNF14FTD23K2 is Cut Tape while PRNF14FTD23K2 is Tape & Reel. Choose based on procurement and assembly workflow.

Q: When should CMF5523K200FHEB be used instead of the RNF series? A: Use CMF5523K200FHEB when the application requires higher power dissipation (0.5W vs 0.25W), better temperature coefficient stability (±50ppm/°C vs ±100ppm/°C), extended temperature operation to 175°C, or moisture-resistant construction. The Vishay Dale CMF series is an upgrade path for demanding thermal or environmental conditions.

Q: Are all substitute parts RoHS3 compliant? A: Yes. PRNF14FTD23K2, RNF14FAD23K2, RNF14FTD23K2, and CMF5523K200FHEB are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: Do the substitute parts fit the same PCB footprint? A: Yes. All parts are axial configuration with comparable dimensions. PRNF14FTD23K2, RNF14FAD23K2, and RNF14FTD23K2 share identical dimensions (0.093" Dia x 0.250" L). CMF5523K200FHEB has slightly smaller dimensions (0.090" Dia x 0.240" L) but remains compatible with standard axial resistor footprints.

Q: What is the temperature coefficient difference and when does it matter? A: PRNF14FTD23K2 and RNF series parts have ±100ppm/°C temperature coefficient, while CMF5523K200FHEB has ±50ppm/°C. The lower coefficient in CMF series means better resistance stability across temperature variations. This matters in precision analog circuits, measurement equipment, or applications with wide operating temperature ranges.
