Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC2K00 is determined by the following critical parameters: resistance value (2 kOhms), tolerance (±1% or better), composition (metal film), and package type (axial). All substitute parts maintain these core electrical characteristics.

Substitutes are categorized into three groups:

Direct Equivalent (Same Packaging): RNMF14FTC2K00 maintains identical electrical specifications with alternative packaging format (Cut Tape vs. Tape & Reel).

Upgrade Options (Enhanced Performance): CMF552K0000BEEB, CMF552K0000BHEB, and CMF552K0000FHEB offer higher power ratings (0.5W vs. 0.25W), improved tolerance (±0.1% for BEEB and BHEB variants), extended operating temperature range (-55°C to 175°C), and moisture-resistant construction. These parts are physically larger to accommodate increased power dissipation.

Direct Replacement (Same Power Rating): CMF502K0000FHEB provides equivalent 0.25W power rating with moisture-resistant features and extended temperature range, maintaining the same electrical tolerance (±1%) as the original part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain ROHS3 compliance and active production status, ensuring long-term availability and regulatory alignment with the original RNF14FTC2K00.

RNMF14FTC2K00 serves as the direct equivalent from Stackpole Electronics Inc, offering identical electrical specifications with miniaturized physical dimensions. This part is suitable for applications where packaging format flexibility is acceptable and inventory sourcing from the same manufacturer is preferred.

CMF502K0000FHEB provides a direct replacement maintaining the 0.25W power rating while introducing moisture-resistant construction and extended operating temperature range to 175°C. Physical dimensions are smaller than the original part. This selection is appropriate for applications requiring enhanced environmental protection without increased power dissipation capability.

CMF552K0000FHEB offers upgrade capability with 0.5W power rating and ±1% tolerance matching the original specification. Moisture-resistant features and extended temperature range provide enhanced reliability. This part accommodates applications with higher power dissipation requirements or stricter environmental conditions.

CMF552K0000BEEB and CMF552K0000BHEB provide the highest performance upgrade path with 0.5W power rating and ±0.1% tolerance (BEEB variant includes ±25ppm/°C temperature coefficient). These selections are appropriate for precision measurement circuits or applications requiring superior tolerance performance beyond the original ±1% specification.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC2K00 be used as a direct drop-in replacement for RNF14FTC2K00?

A: Yes. RNMF14FTC2K00 maintains identical electrical specifications (2 kOhms, ±1%, 0.25W, metal film, axial package). The primary difference is physical size (0.070" Dia x 0.130" L vs. 0.093" Dia x 0.250" L) and packaging format (Cut Tape vs. Tape & Reel). Verify PCB layout accommodates the smaller dimensions before substitution.

Q: What are the key differences between the Stackpole and Vishay Dale substitute options?

A: Vishay Dale CMF series parts introduce moisture-resistant construction and extend the operating temperature range to 175°C compared to 155°C for Stackpole parts. CMF55 series (0.5W variants) provide higher power dissipation capability. CMF50 series (0.25W variant) maintains the original power rating while adding moisture resistance. All Vishay parts are ROHS3 compliant and active in production.

Q: Are the CMF552K0000 variants (0.5W) physically compatible with PCB layouts designed for RNF14FTC2K00?

A: CMF552K0000 parts are slightly smaller in diameter (0.090" vs. 0.093") but similar in length (0.240" vs. 0.250"). Physical compatibility depends on specific PCB hole spacing and component clearance. Verify dimensions against PCB design before substitution.

Q: What tolerance improvement does CMF552K0000BEEB provide?

A: CMF552K0000BEEB offers ±0.1% tolerance compared to ±1% for RNF14FTC2K00, representing a 10-fold improvement in tolerance specification. This part also features ±25ppm/°C temperature coefficient versus ±50ppm/°C for the original part, providing superior temperature stability.

Q: Can CMF502K0000FHEB be used in applications originally designed for RNF14FTC2K00?

A: Yes. CMF502K0000FHEB maintains the 0.25W power rating and ±1% tolerance of the original part. Physical dimensions are smaller (0.065" Dia x 0.150" L), and moisture-resistant construction provides enhanced environmental protection. Verify PCB layout accommodates the reduced size.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RNMF14FTC2K00, CMF552K0000BEEB, CMF552K0000BHEB, CMF552K0000FHEB, and CMF502K0000FHEB) are ROHS3 compliant and maintain regulatory alignment with the original RNF14FTC2K00.
