Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTC536K are qualified based on the following criteria:

• Identical resistance value: 536 kOhms
• Matching tolerance: ±1%
• Equivalent power rating: 0.5W (1/2W)
• Same composition: Metal Film
• Identical package configuration: Axial through-hole
• Matching temperature coefficient: ±50ppm/°C
• Compatible operating temperature range (minimum -55°C to at least 155°C)
• Equivalent regulatory compliance: ROHS3 Compliant

The CMF55536K00FHEB from Vishay Dale meets all substitution criteria while maintaining electrical and mechanical compatibility with the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC536K and CMF55536K00FHEB are active production parts with ROHS3 compliance. The CMF55536K00FHEB provides an extended operating temperature range to 175°C compared to 155°C for the primary part, and includes moisture-resistant construction. Physical dimensions differ, with the CMF55 series featuring a more compact profile. Selection between these parts should be based on specific application requirements regarding temperature operating limits, physical space constraints, and packaging format availability (Tape & Reel versus Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can the CMF55536K00FHEB be used as a direct replacement for the RNF12FTC536K?

A: Yes, the CMF55536K00FHEB meets all core electrical specifications: 536 kOhms resistance, ±1% tolerance, 0.5W power rating, metal film composition, and ±50ppm/°C temperature coefficient. Both parts are axial through-hole components with ROHS3 compliance. Physical dimensions differ, so PCB layout compatibility must be verified.

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

A: The RNF12FTC536K measures 0.108" diameter x 0.344" length (2.75mm x 8.75mm). The CMF55536K00FHEB measures 0.090" diameter x 0.240" length (2.29mm x 6.10mm). The substitute part is more compact in both dimensions.

Q: Are there temperature range differences?

A: The RNF12FTC536K operates from -55°C to 155°C. The CMF55536K00FHEB operates from -55°C to 175°C. For applications requiring operation above 155°C, the CMF55 series provides extended capability.

Q: What packaging formats are available?

A: The RNF12FTC536K is supplied in Tape & Reel (TR) format. The CMF55536K00FHEB is supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and volume considerations.

Q: Do both parts meet the same regulatory standards?

A: Yes, both the RNF12FTC536K and CMF55536K00FHEB are ROHS3 compliant and carry EAR99 ECCN classification with identical HTSUS codes (8533.21.0090).
