Parameter Comparison

Engineering Selection Recommendations

RNF14FTE6K65 (Stackpole Electronics Inc): This substitute is electrically and mechanically identical to the RNF14FAC6K65, with the primary difference being packaging format (Cut Tape vs. Tape & Box) and improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C). Both parts maintain identical physical dimensions, operating temperature range, and compliance certifications. Selection between these two Stackpole variants depends on packaging requirements and procurement format.

CMF506K6500FHEB (Vishay Dale): This cross-manufacturer substitute meets all electrical specifications and compliance requirements. The CMF506K6500FHEB offers an extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C) and includes moisture-resistant features. Physical dimensions are smaller (0.065" Dia x 0.150" L vs. 0.093" Dia x 0.250" L), which may affect board layout compatibility. Both parts are ROHS3 compliant and Active status. Selection of this substitute requires verification of physical space constraints in the application.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTE6K65 be used as a direct replacement for RNF14FAC6K65?

A: Yes. Both parts share identical electrical specifications (6.65 kOhms ±1%, 0.25W), composition (metal film), package type (axial), and physical dimensions. The difference is packaging format (Cut Tape vs. Tape & Box). The RNF14FTE6K65 has a superior temperature coefficient (±25ppm/°C).

Q: Is CMF506K6500FHEB compatible with RNF14FAC6K65 in all applications?

A: Electrical and compliance compatibility is confirmed. However, the CMF506K6500FHEB has smaller physical dimensions (0.065" Dia x 0.150" L vs. 0.093" Dia x 0.250" L). Board layout and mechanical fit must be evaluated before substitution.

Q: What are the key differences between these substitute parts?

A: RNF14FTE6K65 differs only in packaging format and temperature coefficient. CMF506K6500FHEB differs in manufacturer, physical size, temperature coefficient, and operating temperature range. All three parts maintain the same resistance, tolerance, power rating, and compliance status.

Q: Are all three parts ROHS3 compliant?

A: Yes. RNF14FAC6K65, RNF14FTE6K65, and CMF506K6500FHEB are all ROHS3 compliant and REACH unaffected.

Q: Which substitute offers the best temperature stability?

A: RNF14FTE6K65 provides the lowest temperature coefficient at ±25ppm/°C, compared to ±50ppm/°C for both RNF14FAC6K65 and CMF506K6500FHEB.

Q: Can packaging format affect part selection?

A: Yes. RNF14FAC6K65 is supplied in Tape & Box format, while RNF14FTE6K65 and CMF506K6500FHEB are supplied in Cut Tape format. Procurement and assembly processes may require specific packaging formats.
