Substitute Part Grouping Explanation

Substitute parts for the RNF14BAC2K10 are qualified based on the following criteria:

• Resistance value: 2.1 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)

The CMF552K1000BHEB qualifies as a substitute part. While the power rating is upgraded from 0.25W to 0.5W, this represents a higher capability that maintains backward compatibility in circuits designed for the original 0.25W specification. The operating temperature range extends to 175°C (versus 155°C), providing enhanced thermal performance. Physical dimensions remain comparable for standard PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14BAC2K10 and CMF552K1000BHEB meet ROHS3 compliance and REACH unaffected status, qualifying them for equivalent use in applications requiring regulatory adherence. The CMF552K1000BHEB provides increased power dissipation capability (0.5W versus 0.25W) and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C), making it suitable for applications with higher thermal demands or stricter environmental specifications. Physical dimensions are comparable, supporting direct PCB mounting compatibility. Selection between these parts depends on application power requirements and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the CMF552K1000BHEB replace the RNF14BAC2K10 in existing designs?

A: Yes. The CMF552K1000BHEB maintains identical electrical specifications (2.1 kOhms ±0.1%, ±50ppm/°C) and axial package configuration. The higher power rating (0.5W) and extended temperature range represent enhanced capabilities that do not compromise backward compatibility with circuits designed for the original 0.25W specification.

Q: Are there physical mounting differences between these parts?

A: Physical dimensions are comparable. The RNF14BAC2K10 measures 0.093" Dia x 0.250" L, while the CMF552K1000BHEB measures 0.090" Dia x 0.240" L. Both are standard axial through-hole packages suitable for conventional PCB mounting without modification.

Q: What is the significance of the ±0.1% tolerance specification?

A: The ±0.1% tolerance indicates precision-grade resistors suitable for applications requiring tight resistance accuracy. Both parts maintain this specification, ensuring equivalent performance in precision circuits such as measurement instrumentation, calibration networks, and analog signal conditioning.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RNF14BAC2K10 and CMF552K1000BHEB are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards for industrial and commercial applications.

Q: What is the difference between the packaging formats listed?

A: The RNF14BAC2K10 is supplied in Tape & Box (TB) format, while the CMF552K1000BHEB is supplied in Cut Tape (CT) format. Both are standard packaging methods for through-hole resistors; selection depends on assembly process requirements and inventory management preferences.
