RNF14CTC10K0 Equivalent & Substitute Parts

Part Overview

The RNF14CTC10K0 is a 10 kOhms ±0.25% metal film axial through-hole resistor rated at 0.25W (1/4W) manufactured by Stackpole Electronics Inc. This component features flame retardant coating and safety construction, operating across -55°C to 155°C. The part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained while potentially offering improved specifications or alternative packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14CTC10K0 are qualified based on the following criteria:

Electrical Compatibility: Resistance value (10 kOhms) and composition (metal film) must be identical. Tolerance and temperature coefficient may be equal or superior (tighter tolerance, lower temperature coefficient).

Mechanical Compatibility: Package type must be axial through-hole. Physical dimensions must be compatible with PCB layouts designed for the original part.

Power Rating: Equal or higher power rating is acceptable; lower power ratings are not substitutable.

Regulatory Compliance: RoHS3 compliance and flame retardant construction must be maintained.

Packaging Format: Original packaging is Tape & Reel (TR); Cut Tape (CT) alternatives are acceptable for equivalent electrical and mechanical specifications.

Two substitute parts meet these criteria: RNF14BTE10K0 (same manufacturer, improved tolerance and temperature coefficient, same power rating) and CMF5510K000BEEB (alternative manufacturer, improved tolerance and temperature coefficient, higher power rating).

Parameter Comparison

Engineering Selection Recommendations

RNF14BTE10K0: This substitute offers improved tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical power rating and operating temperature range. Same manufacturer and series ensure design continuity. Suitable for applications requiring tighter tolerance specifications without thermal performance compromise.

CMF5510K000BEEB: This substitute provides the highest performance specifications with ±0.1% tolerance, ±25ppm/°C temperature coefficient, and elevated power rating (0.5W versus 0.25W). Extended operating temperature range (-55°C to 175°C) and moisture-resistant construction offer additional environmental protection. Suitable for applications with higher thermal stress or moisture exposure requirements. Alternative manufacturer (Vishay Dale) maintains ROHS3 compliance and equivalent regulatory status.

Both substitutes maintain Active product status and full regulatory compliance (ROHS3, REACH Unaffected, EAR99).

Frequently Asked Questions (FAQ)

Q: Can RNF14BTE10K0 directly replace RNF14CTC10K0 in existing designs?

A: Yes. Both parts share identical resistance (10 kOhms), power rating (0.25W), operating temperature range (-55°C to 155°C), and axial package configuration. RNF14BTE10K0 provides superior tolerance and temperature coefficient specifications. Packaging format differs (Cut Tape versus Tape & Reel), which affects procurement and assembly processes but not electrical or mechanical compatibility.

Q: Is CMF5510K000BEEB suitable for applications designed for RNF14CTC10K0?

A: Yes, with consideration for power rating and thermal characteristics. CMF5510K000BEEB maintains identical resistance and axial package type. The 0.5W power rating (versus 0.25W) is a performance upgrade suitable for higher dissipation environments. Extended operating temperature range (-55°C to 175°C) provides additional thermal margin. Moisture-resistant construction offers enhanced environmental protection. Physical dimensions are comparable (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L), maintaining PCB layout compatibility.

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

A: RNF14BTE10K0 maintains identical specifications to the main part except for improved tolerance and temperature coefficient, offering a direct performance upgrade from the same manufacturer. CMF5510K000BEEB provides higher power rating (0.5W), extended temperature range, and moisture resistance from an alternative qualified manufacturer. Selection depends on application thermal and environmental requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. RNF14CTC10K0, RNF14BTE10K0, and CMF5510K000BEEB are all ROHS3 compliant with REACH Unaffected status and EAR99 classification.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats are logistics and assembly considerations only. Electrical and mechanical specifications remain identical regardless of packaging format.
