Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Equivalents maintain identical electrical specifications (31.6 kOhms, ±1% tolerance, 0.25W power rating, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) with variations only in packaging format (Tape & Reel vs. Cut Tape). These parts are functionally interchangeable in circuit applications.

Upgraded Substitutes provide enhanced performance through tighter tolerance (±0.5% vs. ±1%) or increased power rating (0.5W vs. 0.25W), with corresponding improvements in temperature coefficient specifications. These parts are suitable for applications requiring higher precision or thermal headroom.

Cross-Manufacturer Substitutes from alternative manufacturers meet the same electrical and mechanical specifications while offering different sourcing options and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: RNF14FAD31K6 and RNF14FTD31K6 are functionally equivalent to PRNF14FTD31K6. Selection between these parts depends on packaging requirements and inventory availability. RNF14FTD31K6 offers the highest stock level (16337 Pcs) in Cut Tape format.

For Enhanced Tolerance Applications: RNF14DTC31K6 provides ±0.5% tolerance with ±50ppm/°C temperature coefficient, suitable for precision circuit designs requiring tighter resistance control. This part maintains the same 0.25W power rating and operating temperature range.

For Increased Power Dissipation: CMF5531K600FHEB from Vishay Dale offers 0.5W power rating with ±50ppm/°C temperature coefficient and extended operating range to 175°C. This part is suitable for applications with higher thermal requirements while maintaining ±1% tolerance.

All listed parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can RNF14FAD31K6 replace PRNF14FTD31K6 directly in production? A: Yes. Both parts share identical electrical specifications (31.6 kOhms, ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C). The difference is packaging format: PRNF14FTD31K6 is supplied in Tape & Reel while RNF14FAD31K6 is Cut Tape. Circuit performance is equivalent.

Q: What is the difference between RNF14DTC31K6 and PRNF14FTD31K6? A: RNF14DTC31K6 provides tighter tolerance (±0.5% vs. ±1%) and lower temperature coefficient (±50ppm/°C vs. ±100ppm/°C). Both maintain 0.25W power rating and identical resistance value. RNF14DTC31K6 is suitable for precision applications where tolerance and temperature stability are critical.

Q: Is CMF5531K600FHEB compatible with PRNF14FTD31K6? A: CMF5531K600FHEB is compatible from an electrical standpoint (31.6 kOhms, ±1% tolerance) but differs in power rating (0.5W vs. 0.25W) and temperature coefficient (±50ppm/°C vs. ±100ppm/°C). It is suitable for applications requiring higher power dissipation or extended operating temperature to 175°C. Physical dimensions are similar but not identical.

Q: What packaging formats are available? A: PRNF14FTD31K6 is supplied in Tape & Reel format. Direct equivalents RNF14FAD31K6 and RNF14FTD31K6 are available in Cut Tape format. All parts use axial through-hole configuration with identical lead dimensions (0.093" Dia x 0.250" L).

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts (PRNF14FTD31K6, RNF14FAD31K6, RNF14FTD31K6, RNF14DTC31K6, and CMF5531K600FHEB) are ROHS3 compliant and REACH unaffected.
