Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Resistance Value: Must be 12.7 kOhms
• Tolerance: Must be ±1%
• Composition: Must be Metal Film
• Package Type: Must be Axial
• Compliance: Must maintain ROHS3 and REACH compliance

Two substitute parts meet these core criteria:

Direct Substitute (Packaging Variant): RNF14FTD12K7 is identical to the main part in all electrical and mechanical specifications, differing only in packaging format (Cut Tape vs. Tape & Box). This substitution is interchangeable for circuit design purposes.

Upgrade Substitute (Enhanced Performance): CMF5512K700FHEB from Vishay Dale maintains the same resistance, tolerance, and axial package but offers enhanced specifications including 0.5W power rating, improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). This part is suitable for applications requiring higher power dissipation or superior thermal stability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: RNF14FTD12K7 is the appropriate choice when packaging format flexibility is acceptable. Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications and certifications. Selection between Tape & Box and Cut Tape formats depends on assembly process requirements and inventory management practices.

For Enhanced Performance Applications: CMF5512K700FHEB is suitable for circuits requiring higher power dissipation capability or operation in elevated temperature environments. The 0.5W rating provides additional thermal margin, and the ±50ppm/°C temperature coefficient delivers superior frequency stability compared to the ±100ppm/°C specification of the main part. All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across all substitution options.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD12K7 be used as a direct replacement for RNF14FAD12K7?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: RNF14FAD12K7 is supplied in Tape & Box format while RNF14FTD12K7 is supplied in Cut Tape format. Circuit performance is unaffected by this packaging distinction.

Q: What are the advantages of using CMF5512K700FHEB over the original part?

A: CMF5512K700FHEB offers three performance enhancements: doubled power rating (0.5W vs. 0.25W), improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), and extended maximum operating temperature (175°C vs. 155°C). These specifications make it suitable for higher-power or thermally demanding applications.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use axial package configuration with identical lead spacing and mechanical dimensions suitable for standard through-hole assembly. PCB layout modifications are not required for substitution.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. RNF14FTD12K7 and CMF5512K700FHEB are both ROHS3 compliant and REACH unaffected, matching the regulatory status of RNF14FAD12K7.

Q: Which substitute should be selected for cost optimization?

A: RNF14FTD12K7 typically offers cost parity with the main part while providing superior inventory availability (8874 units vs. 726 units). CMF5512K700FHEB represents a performance upgrade and may carry different pricing based on enhanced specifications.
