Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTC93R1 are qualified based on the following critical parameters:

• Resistance Value: Exact match at 93.1 Ohms
• Tolerance: Identical at ±1%
• Power Rating: Equivalent at 0.5W (1/2W)
• Composition: Metal film construction
• Package Configuration: Axial through-hole format
• Temperature Coefficient: Matching ±50ppm/°C specification
• Regulatory Compliance: ROHS3 Compliant status

The CMF5593R100FHEB from Vishay Dale meets all substitution criteria. While physical dimensions differ slightly and the operating temperature maximum extends to 175°C (versus 155°C for the primary part), the electrical performance and functional characteristics remain equivalent for standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC93R1 and CMF5593R100FHEB are Active status components with full ROHS3 compliance and REACH unaffected designation. Selection between these parts should be based on:

Primary Part (RNF12FTC93R1): Choose when Stackpole sourcing is preferred or when tape & reel packaging format is required for automated assembly processes. Suitable for standard industrial applications within the -55°C to 155°C temperature envelope.

Substitute Part (CMF5593R100FHEB): Choose when Vishay Dale supply chain is more accessible or when extended temperature performance to 175°C is beneficial. The added moisture resistant feature provides enhanced environmental protection. Cut tape packaging is suitable for manual assembly or lower-volume production runs.

Both parts satisfy identical electrical requirements and are mechanically compatible in standard axial through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can CMF5593R100FHEB replace RNF12FTC93R1 in existing designs?

A: Yes. Both components share identical resistance value (93.1 Ohms), tolerance (±1%), power rating (0.5W), and temperature coefficient (±50ppm/°C). Axial package compatibility ensures direct PCB footprint compatibility.

Q: What is the difference in physical dimensions?

A: RNF12FTC93R1 measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm). CMF5593R100FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). The substitute part is physically smaller, which may be advantageous for space-constrained layouts but requires verification of lead spacing in existing designs.

Q: Does the extended operating temperature of CMF5593R100FHEB affect substitution?

A: No. The extended maximum temperature (175°C versus 155°C) represents an enhancement, not a limitation. Applications operating within the original -55°C to 155°C range experience no performance change.

Q: Are packaging format differences significant?

A: Packaging format (Tape & Reel versus Cut Tape) affects procurement and assembly processes but not electrical or mechanical performance. Tape & Reel is optimized for high-volume automated assembly; Cut Tape suits manual or lower-volume applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 Compliant, REACH Unaffected, and carry EAR99 ECCN classification with identical HTSUS coding (8533.21.0090).
