Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12BTC2K00 are qualified based on the following critical parameters:

• Resistance value: 2 kOhms (exact match required)
• Tolerance: ±0.1% (precision specification)
• Power rating: 0.5W minimum
• Composition: Metal film construction
• Package: Axial through-hole configuration
• Temperature coefficient: ±50ppm/°C or better
• Compliance: ROHS3 and REACH requirements

The CMF552K0000BHEB from Vishay Dale meets all electrical and mechanical substitution criteria. Both components share identical resistance, tolerance, power rating, composition, and temperature coefficient specifications. Physical dimensions differ slightly, but both maintain standard axial package compatibility for through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12BTC2K00 and CMF552K0000BHEB are active production components with full ROHS3 compliance and REACH unaffected status. The CMF552K0000BHEB provides an extended operating temperature range to 175°C compared to 155°C for the RNF12BTC2K00, and includes moisture resistant features. Electrical performance is identical across all critical parameters. Selection between these components should be based on packaging format requirements (Tape & Reel versus Cut Tape), inventory availability, and thermal operating environment specifications.

Frequently Asked Questions (FAQ)

Q: Can the CMF552K0000BHEB replace the RNF12BTC2K00 in all applications?

A: Yes, provided the operating temperature does not exceed 155°C. The CMF552K0000BHEB supports operation to 175°C, making it suitable for higher temperature environments. All electrical specifications are identical.

Q: What is the difference in physical dimensions between these parts?

A: The RNF12BTC2K00 measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm). The CMF552K0000BHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both are standard axial packages compatible with through-hole PCB layouts, though board spacing may require verification for tight layouts.

Q: Are there packaging format differences?

A: Yes. The RNF12BTC2K00 is supplied in Tape & Reel (TR) format, while the CMF552K0000BHEB is supplied in Cut Tape (CT) format. Select based on assembly process requirements and volume needs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Q: What additional features does the CMF552K0000BHEB provide?

A: The CMF552K0000BHEB includes moisture resistant properties in addition to flame retardant coating and safety features, providing enhanced environmental protection in humid or moisture-prone applications.
