Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRNF14FTD2K10 is determined by the following criteria:

Critical Parameters (Must Match):

• Resistance value: 2.1 kOhms
• Tolerance: ±1% or better
• Composition: Metal Film
• Package: Axial configuration
• RoHS Compliance: ROHS3 Compliant

Allowable Variations:

• Power rating: Equal to or greater than 0.25W
• Temperature coefficient: Equal to or lower absolute value
• Operating temperature range: Must encompass or equal the specified range
• Packaging format: Cut Tape (CT) or Tape & Reel (TR) are interchangeable for component selection

Substitute parts are grouped into direct equivalents and upgrades based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: RNF14FTD2K10 (Stackpole Electronics Inc) is a direct equivalent to PRNF14FTD2K10, maintaining identical electrical and mechanical specifications with the same packaging format variation (Cut Tape vs. Tape & Reel).

Upgrade Options:

CMF552K1000FHEB (Vishay Dale) provides increased power rating (0.5W vs. 0.25W) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C) with ±1% tolerance matching the original specification. Temperature coefficient is ±50ppm/°C.

All substitute parts maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD2K10 be used as a direct replacement for PRNF14FTD2K10? A: Yes. RNF14FTD2K10 is a direct equivalent with identical electrical specifications (2.1 kOhms ±1%, 0.25W, metal film, axial package). The difference is packaging format (Cut Tape vs. Tape & Reel), which does not affect component functionality.

Q: What is the difference between the Stackpole and Vishay Dale substitute options? A: Stackpole options (RNF14FTD2K10, RNF14FTE2K10) maintain the 0.25W power rating. Vishay Dale options (CMF552K1000BHEB, CMF552K1000FHEB) provide 0.5W power rating and extended temperature range to 175°C. RNF14FTE2K10 offers improved temperature coefficient (±25ppm/°C). CMF552K1000BHEB offers tighter tolerance (±0.1%).

Q: Are the physical dimensions compatible between all substitute parts? A: All parts use axial package configuration. PRNF14FTD2K10, RNF14FTD2K10, and RNF14FTE2K10 share identical dimensions (0.093" Dia x 0.250" L). Vishay Dale parts (CMF552K1000BHEB, CMF552K1000FHEB) have slightly different dimensions (0.090" Dia x 0.240" L) but maintain axial package compatibility for standard through-hole PCB applications.

Q: Which substitute part should be selected for high-temperature applications? A: CMF552K1000BHEB and CMF552K1000FHEB support operating temperatures up to 175°C, compared to 155°C for Stackpole parts. Selection depends on specific temperature requirements and tolerance specifications needed for the application.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (RNF14FTD2K10, RNF14FTE2K10, CMF552K1000BHEB, CMF552K1000FHEB) are ROHS3 compliant and maintain REACH Unaffected status.
