Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTC2K61 are qualified based on the following critical parameters:

• Electrical Equivalence: Resistance value of 2.61 kOhms with ±1% tolerance
• Power Rating: 0.5W (1/2W) minimum
• Composition: Metal film construction
• Package Configuration: Axial through-hole format
• Temperature Coefficient: ±50ppm/°C
• Compliance: ROHS3 compliance and REACH unaffected status
• Safety Features: Flame retardant coating and safety construction

The CMF552K6100FHEB from Vishay Dale meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical specifications and mechanical compatibility, with differences limited to physical dimensions and extended operating temperature range in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC2K61 and CMF552K6100FHEB are active production components with full ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The CMF552K6100FHEB offers an extended operating temperature range to 175°C compared to 155°C for the RNF12FTC2K61, and includes additional moisture resistance features. The substitute part features a more compact physical profile while maintaining identical electrical performance. Selection between these parts should be based on available inventory, packaging format requirements (Tape & Reel versus Cut Tape), and thermal operating envelope specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the CMF552K6100FHEB directly replace the RNF12FTC2K61 in existing designs?

A: Yes. Both parts share identical resistance values (2.61 kOhms), tolerance (±1%), power rating (0.5W), temperature coefficient (±50ppm/°C), and composition (metal film). Both are axial through-hole components with two terminations. The primary consideration is physical size difference: the CMF552K6100FHEB is more compact (0.090" Dia x 0.240" L versus 0.108" Dia x 0.344" L), which may affect PCB layout compatibility.

Q: What are the key differences between these two parts?

A: The CMF552K6100FHEB provides an extended operating temperature range (-55°C to 175°C versus -55°C to 155°C), includes moisture resistance features, and features a smaller physical footprint. Electrical performance and compliance certifications are equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both the RNF12FTC2K61 and CMF552K6100FHEB are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.

Q: What packaging formats are available?

A: The RNF12FTC2K61 is supplied in Tape & Reel (TR) format. The CMF552K6100FHEB is available in Cut Tape (CT) format with Tape & Reel (TR) packaging options.

Q: Does the physical size difference affect electrical performance?

A: No. Physical dimensions do not affect electrical characteristics. Size differences are relevant only for PCB layout and mechanical fit considerations.
