Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRNF14FTD2K43 is determined by the following critical parameters: resistance value (2.43 kOhms), tolerance (±1% minimum), power rating (0.25W minimum), composition (metal film), and package configuration (axial). All identified substitutes maintain these core electrical specifications and mechanical compatibility.

The substitute parts are categorized as follows:

Direct Equivalent: RNF14FTD2K43 (Stackpole Electronics Inc) — identical electrical and mechanical specifications with alternative packaging (Cut Tape vs. Tape & Reel).

Upgrade Options: Parts with enhanced performance characteristics while maintaining core compatibility:

• RNF14BTC2K43 — improved tolerance (±0.1%) and lower temperature coefficient (±50ppm/°C)
• CMF552K4300FHEB — higher power rating (0.5W) and extended operating temperature range (-55°C to 175°C)

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD2K43 (Direct Equivalent): Select this part when packaging format (Cut Tape) is acceptable and inventory availability is a priority. Electrical and thermal characteristics are identical to the primary part.

RNF14BTC2K43 (Upgrade Option): Select this part for applications requiring tighter tolerance control (±0.1%) and improved temperature stability (±50ppm/°C). All other specifications remain compatible with the original design.

CMF552K4300FHEB (Upgrade Option): Select this part for applications requiring higher power dissipation capability (0.5W vs. 0.25W) or extended operating temperature range (-55°C to 175°C). This part is manufactured by Vishay Dale and maintains ROHS3 and REACH compliance.

All substitute parts maintain active product status and full regulatory compliance (ROHS3 Compliant, REACH Unaffected, ECCN EAR99).

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD2K43 be used as a direct replacement for PRNF14FTD2K43?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: PRNF14FTD2K43 is supplied in Tape & Reel, while RNF14FTD2K43 is supplied in Cut Tape. Axial configuration and all electrical parameters are identical.

Q: What is the primary advantage of RNF14BTC2K43 over the original part?

A: RNF14BTC2K43 provides tighter tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±50ppm/°C vs. ±100ppm/°C), resulting in improved accuracy and stability across the operating temperature range. Power rating and package remain unchanged.

Q: Can CMF552K4300FHEB be used in place of PRNF14FTD2K43?

A: Yes, with design considerations. CMF552K4300FHEB is mechanically compatible (axial package) and electrically compatible (2.43 kOhms, ±1% tolerance). The primary differences are higher power rating (0.5W vs. 0.25W) and extended temperature range (-55°C to 175°C vs. -55°C to 155°C). Physical dimensions are slightly different (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L), which may affect PCB layout in space-constrained applications.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original PRNF14FTD2K43.

Q: Which substitute part should be selected for high-temperature applications?

A: CMF552K4300FHEB supports the highest operating temperature (175°C maximum) compared to the original part (155°C maximum). This part is suitable for applications requiring extended thermal performance.
