Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC5K76 is determined by the following critical parameters:

• Resistance value: 5.76 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CMF555K7600FHEB from Vishay Dale meets all substitution criteria. Both parts share identical electrical specifications, composition, and compliance certifications. The substitute part operates across an extended temperature range (-55°C to 175°C) compared to the main part (-55°C to 155°C), providing additional thermal margin. Physical dimensions differ slightly due to manufacturer design variations, but both maintain standard axial package form factors suitable for through-hole PCB assembly.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC5K76 and CMF555K7600FHEB are Active products with full ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for industrial and commercial applications. Selection between these parts should be based on:

• Packaging format requirements: The main part is supplied in Tape & Reel format, while the substitute is supplied in Cut Tape format. Verify your assembly process compatibility.
• Physical dimensions: The substitute part is more compact (0.090" Dia x 0.240" L versus 0.108" Dia x 0.344" L). Confirm PCB layout and spacing accommodate the selected component.
• Temperature margin: The substitute part extends the upper operating temperature to 175°C, providing additional thermal headroom in high-temperature applications.
• Moisture resistance: The substitute part includes moisture-resistant features, beneficial for humid or corrosive environments.
• Inventory availability: Current stock levels are 965 units (main part) and 1895 units (substitute), supporting procurement decisions based on lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can CMF555K7600FHEB be used as a direct replacement for RNF12FTC5K76?

A: Yes. Both parts share identical electrical specifications (5.76 kOhms ±1%, 0.5W, ±50ppm/°C), composition (metal film), and regulatory compliance (ROHS3, REACH Unaffected). Physical dimensions differ slightly, requiring verification that PCB layout accommodates the substitute part's smaller form factor (0.090" Dia x 0.240" L).

Q: What are the key differences between these parts?

A: The primary differences are physical dimensions, operating temperature range (155°C versus 175°C upper limit), packaging format (Tape & Reel versus Cut Tape), and the substitute part includes moisture-resistant features. Electrical performance and tolerance specifications are identical.

Q: Are there any compatibility concerns with PCB assembly?

A: The substitute part is more compact than the main part. Verify that your PCB layout, component spacing, and through-hole positioning accommodate the smaller axial package dimensions before substitution.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and safety regulations for industrial applications.

Q: Which part should I select for high-temperature applications?

A: The CMF555K7600FHEB operates to 175°C, providing a 20°C higher upper temperature limit compared to the RNF12FTC5K76 (155°C). Select based on your application's maximum operating temperature requirement.

Q: What packaging formats are available?

A: The RNF12FTC5K76 is supplied in Tape & Reel (TR) format. The CMF555K7600FHEB is supplied in Cut Tape (CT) format. Confirm your assembly equipment and procurement process compatibility with the selected packaging format.
