Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC1K02 is determined by the following critical parameters:

• Electrical Match: Resistance value of 1.02 kOhms with ±1% tolerance
• Power Rating: 0.5W (1/2W) minimum
• Composition: Metal film construction
• Package Configuration: Axial through-hole format with 2 terminations
• Temperature Coefficient: ±50ppm/°C stability
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification
• Safety Features: Flame retardant coating and safety-grade designation

The CMF551K0200FHEB from Vishay Dale meets all substitution criteria while maintaining identical electrical performance and regulatory status. Physical dimensions differ slightly due to manufacturing design, but both components function identically in axial through-hole applications.

Engineering Selection Recommendations

Both the RNF12FTC1K02 and CMF551K0200FHEB maintain Active product status and full ROHS3 compliance with identical electrical specifications. Selection between these components should be based on:

RNF12FTC1K02 (Stackpole Electronics Inc): Select when Tape & Reel packaging is required for automated assembly processes or when the larger physical dimensions (0.108" Dia x 0.344" L) are preferred for board layout compatibility.

CMF551K0200FHEB (Vishay Dale): Select when Cut Tape packaging is acceptable, when compact dimensions (0.090" Dia x 0.240" L) are advantageous for space-constrained designs, or when the extended operating temperature range to 175°C provides additional thermal margin. The moisture-resistant feature offers enhanced environmental protection in humid applications.

Both components satisfy identical regulatory requirements (ROHS3, REACH Unaffected, EAR99) and maintain the same temperature coefficient and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can CMF551K0200FHEB replace RNF12FTC1K02 in existing designs?

A: Yes. Both components share identical resistance value (1.02 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), temperature coefficient (±50ppm/°C), and regulatory compliance. The primary differences are physical dimensions and packaging format. Verify that board layout accommodates the smaller CMF551K0200FHEB dimensions (0.090" Dia x 0.240" L) or that the larger RNF12FTC1K02 dimensions (0.108" Dia x 0.344" L) fit your application.

Q: What is the difference in packaging between these parts?

A: The RNF12FTC1K02 is supplied in Tape & Reel (TR) format, suitable for high-volume automated pick-and-place assembly. The CMF551K0200FHEB is supplied in Cut Tape (CT) format, typically used for lower-volume or manual assembly processes. Both formats contain identical components with different delivery methods.

Q: Does the extended temperature range of CMF551K0200FHEB (-55°C ~ 175°C) affect substitution?

A: No. The extended upper temperature limit of 175°C on the CMF551K0200FHEB provides additional thermal margin compared to the RNF12FTC1K02 specification of 155°C. This makes the Vishay component suitable for all applications where the Stackpole component functions, including those operating at the RNF12FTC1K02 maximum temperature.

Q: Are there any compliance or certification differences?

A: No. Both components are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. Regulatory status is identical.

Q: What does the moisture-resistant feature on CMF551K0200FHEB provide?

A: The moisture-resistant feature on the Vishay component offers enhanced protection in high-humidity environments. Both components include flame retardant coating and safety-grade construction. The additional moisture resistance on CMF551K0200FHEB is a supplementary feature that does not affect electrical substitution but may provide environmental advantages in specific applications.
