Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC53R6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 53.6 Ohms (exact match required)
• Tolerance: ±1% (no deviation permitted)
• Power rating: 0.5W / 1/2W (functional equivalence)
• Composition: Metal Film (electrical performance class)
• Temperature coefficient: ±50ppm/°C (stability specification)
• Package configuration: Axial through-hole (mechanical compatibility)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (mandatory)

The CMF5553R600FHEB from Vishay Dale meets all substitution criteria. While it features an extended operating temperature range (-55°C ~ 175°C) and additional moisture resistance properties, these represent functional enhancements that do not compromise compatibility. Packaging format differs (Cut Tape vs. Tape & Reel) and physical dimensions vary slightly, but both maintain axial through-hole configuration suitable for identical PCB footprints.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC53R6 and CMF5553R600FHEB are Active products with full regulatory compliance (ROHS3 Compliant, REACH Unaffected). Selection between these components should be based on:

• Supply chain availability: RNF12FTC53R6 maintains 1116 units in stock; CMF5553R600FHEB maintains 1622 units in stock
• Packaging requirements: RNF12FTC53R6 supplied in Tape & Reel format; CMF5553R600FHEB supplied in Cut Tape format
• Temperature margin requirements: CMF5553R600FHEB provides extended upper operating temperature to 175°C versus 155°C for RNF12FTC53R6
• Environmental exposure: CMF5553R600FHEB includes moisture resistance feature for applications in humid or corrosive environments

Both components satisfy identical electrical and mechanical requirements for standard through-hole PCB assembly applications.

Frequently Asked Questions (FAQ)

Q: Can CMF5553R600FHEB replace RNF12FTC53R6 in existing designs?

A: Yes. Both components share identical resistance value (53.6 Ohms), tolerance (±1%), power rating (0.5W), composition (metal film), and temperature coefficient (±50ppm/°C). Both are axial through-hole packages with equivalent PCB footprints. Regulatory compliance is identical (ROHS3, REACH Unaffected).

Q: What is the difference in physical dimensions?

A: RNF12FTC53R6 measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm). CMF5553R600FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). The CMF variant is physically smaller but maintains axial lead configuration compatible with standard through-hole spacing.

Q: Does the extended temperature range of CMF5553R600FHEB affect compatibility?

A: No. The CMF5553R600FHEB operating range (-55°C ~ 175°C) encompasses the RNF12FTC53R6 range (-55°C ~ 155°C). This represents a functional enhancement with no compatibility impact.

Q: Are packaging format differences significant?

A: Packaging format (Tape & Reel vs. Cut Tape) affects supply chain logistics and assembly line integration but does not impact electrical or mechanical performance. Component selection should align with existing procurement and assembly processes.

Q: What certifications apply to both parts?

A: Both components are ROHS3 Compliant and REACH Unaffected. Both carry EAR99 export classification and 8533.21.0090 HTSUS code.
