Key Parameters

Substitute Part Grouping Explanation

Substitution of the PRNF14FTD48K7 is determined by the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 48.7 kOhms
• Tolerance: ±1%
• Composition: Metal Film

Mechanical Parameters (Must Be Compatible):

• Package type: Axial configuration
• Physical dimensions: Compatible with 0.093" Dia x 0.250" L footprint

Compliance & Status:

• RoHS3 compliance required
• Active product status

The substitute part CMF5548K700FHEB meets these core substitution criteria. While the power rating is higher (0.5W vs 0.25W) and operating temperature range is extended (-55°C ~ 175°C vs -55°C ~ 155°C), these represent performance enhancements that do not prevent substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

Both the PRNF14FTD48K7 and CMF5548K700FHEB are Active products with RoHS3 compliance. The CMF5548K700FHEB substitute offers enhanced specifications including higher power dissipation capability (0.5W vs 0.25W), extended operating temperature range to 175°C, and improved temperature stability (±50ppm/°C vs ±100ppm/°C). Selection between these parts depends on application power dissipation requirements and thermal operating conditions. Both components maintain identical electrical characteristics for resistance value and tolerance, ensuring functional equivalence in signal conditioning and biasing circuits.

Frequently Asked Questions (FAQ)

Q: Can CMF5548K700FHEB replace PRNF14FTD48K7 in all applications?

A: Yes, the CMF5548K700FHEB is electrically and mechanically compatible as a substitute. Both components have identical 48.7 kOhms ±1% specifications and axial package configuration. The substitute offers higher power rating and extended temperature range, which do not prevent substitution.

Q: What are the physical dimension differences?

A: PRNF14FTD48K7 dimensions are 0.093" Dia x 0.250" L (2.35mm x 6.35mm). CMF5548K700FHEB dimensions are 0.090" Dia x 0.240" L (2.29mm x 6.10mm). Both are axial configuration and compatible with standard through-hole PCB layouts.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: Why does the substitute have a higher power rating?

A: The CMF5548K700FHEB is rated at 0.5W (1/2W) compared to the original 0.25W (1/4W). This represents a design enhancement that provides additional thermal margin in applications. The higher power rating does not affect compatibility in circuits designed for 0.25W operation.

Q: What is the temperature coefficient difference impact?

A: The substitute CMF5548K700FHEB has ±50ppm/°C temperature coefficient versus ±100ppm/°C for the original. This indicates superior temperature stability, which is beneficial for precision applications but does not prevent substitution in standard signal conditioning circuits.
