Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC2K10 are grouped based on the following criteria:

Primary Substitution Criteria:

• Resistance value: 2.1 kOhms (exact match required)
• Tolerance: ±1% or better (±0.1% is acceptable as upgrade)
• Composition: Metal Film (required)
• Package: Axial (required)
• Compliance: ROHS3 Compliant (required)

Acceptable Parameter Variations:

• Power rating: Equal or greater than 0.25W
• Operating temperature range: Equal or greater than -55°C ~ 155°C
• Temperature coefficient: ±50ppm/°C or better
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) are interchangeable for component selection

Substitute Categories:

1. Direct Equivalent (Same Specifications): RNF14FTE2K10 - Identical electrical specifications with improved temperature coefficient (±25ppm/°C vs ±50ppm/°C) and different packaging format (Cut Tape vs Tape & Reel).

2. Upgraded Substitutes (Enhanced Specifications): CMF552K1000BHEB and CMF552K1000FHEB - Higher power rating (0.5W vs 0.25W), improved tolerance (±0.1% for BHEB variant), extended operating temperature range (-55°C ~ 175°C), and moisture resistant features.

3. Manufacturer Recommended Substitute (Same Power Rating): CMF502K1000FHEB - Equivalent power rating (0.25W), same tolerance (±1%), compact axial package, extended operating temperature range (-55°C ~ 175°C), and moisture resistant features.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTE2K10 (Stackpole Electronics Inc) Select this substitute when packaging format change from Tape & Reel to Cut Tape is acceptable. This part maintains identical electrical specifications with an improved temperature coefficient of ±25ppm/°C, providing enhanced stability. Both parts are Active status and ROHS3 compliant with equivalent compliance certifications.

CMF552K1000BHEB (Vishay Dale) Select this substitute when higher power dissipation capability is required. This part offers 0.5W power rating with superior tolerance of ±0.1%, extended operating temperature range to 175°C, and moisture resistant construction. Suitable for applications requiring enhanced reliability and tighter tolerance specifications. Active status and ROHS3 compliant.

CMF552K1000FHEB (Vishay Dale) Select this substitute when higher power rating and extended temperature range are needed while maintaining ±1% tolerance. This part provides 0.5W power rating, -55°C ~ 175°C operating range, and moisture resistant features. Active status and ROHS3 compliant.

CMF502K1000FHEB (Vishay Dale) Select this substitute when maintaining the original 0.25W power rating is required with enhanced environmental protection. This part matches the power specification of the original component while providing extended operating temperature range to 175°C and moisture resistant construction. Active status and ROHS3 compliant. Compact axial package dimensions (0.065" Dia x 0.150" L) may require PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTE2K10 be used as a direct replacement for RNF14FTC2K10? A: Yes. Both parts have identical electrical specifications (2.1 kOhms, ±1%, 0.25W, metal film, axial package). The primary difference is packaging format (Cut Tape vs Tape & Reel) and improved temperature coefficient (±25ppm/°C vs ±50ppm/°C). Electrical performance is equivalent.

Q: What is the difference between the Stackpole and Vishay Dale substitutes? A: Stackpole RNF14FTE2K10 maintains identical specifications with improved temperature stability. Vishay Dale CMF series parts offer enhanced features including moisture resistant construction and extended operating temperature range to 175°C. CMF552 variants provide higher power ratings (0.5W), while CMF502 maintains the original 0.25W rating.

Q: Can I use CMF552K1000BHEB or CMF552K1000FHEB in place of RNF14FTC2K10? A: Yes, these are valid substitutes. Both provide higher power ratings (0.5W vs 0.25W), extended temperature range (-55°C ~ 175°C vs -55°C ~ 155°C), and moisture resistant features. The CMF552K1000BHEB offers superior tolerance (±0.1% vs ±1%). These upgrades are suitable for applications requiring enhanced performance margins.

Q: Is CMF502K1000FHEB compatible with the original RNF14FTC2K10 footprint? A: Both parts use axial package configuration. However, CMF502K1000FHEB has smaller physical dimensions (0.065" Dia x 0.150" L) compared to RNF14FTC2K10 (0.093" Dia x 0.250" L). Verify PCB layout and spacing requirements before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RNF14FTC2K10 and all listed substitutes are ROHS3 compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What tolerance should I select for critical circuit applications? A: For applications requiring tighter tolerance control, CMF552K1000BHEB offers ±0.1% tolerance compared to ±1% in the original part and other substitutes. This provides superior resistance value accuracy.

Q: Can packaging format (Tape & Reel vs Cut Tape) affect component performance? A: No. Packaging format affects handling and assembly processes only. Electrical and mechanical performance of the component itself is independent of whether it is supplied in Tape & Reel or Cut Tape format.
