• Composition: Metal Film
• Package: Axial through-hole
• Temperature coefficient: ±50ppm/°C
• RoHS compliance: ROHS3 Compliant

The identified substitutes are manufactured by Vishay Dale under the CMF series. Both CMF553K3200FHEB and CMF553K3200FHEK meet the core electrical specifications and axial package requirements. Physical dimensions differ slightly between manufacturers, but both maintain compatibility with standard through-hole PCB layouts for axial components.

Parameter Comparison

Engineering Selection Recommendations

Both CMF553K3200FHEB and CMF553K3200FHEK meet the electrical and compliance requirements for substitution with the RNF12FTC3K32.

CMF553K3200FHEB is supplied in Cut Tape (CT) packaging and maintains ROHS3 Compliant status with REACH Unaffected classification. This variant provides 3199 units in current inventory.

CMF553K3200FHEK is supplied in Bulk packaging and maintains ROHS3 Compliant status. REACH Status is listed as REACH Affected for this variant. This variant provides 986 units in current inventory.

Selection between these substitutes depends on packaging requirements and supply chain compliance needs. Both substitutes provide extended operating temperature range (-55°C ~ 175°C) compared to the original part (-55°C ~ 155°C), and both include moisture-resistant features in addition to flame retardant coating.

Frequently Asked Questions (FAQ)

Q: Can CMF553K3200FHEB and CMF553K3200FHEK be used interchangeably with RNF12FTC3K32?

A: Both Vishay Dale parts meet the core electrical specifications: 3.32 kOhms ±1% resistance, 0.5W power rating, metal film composition, ±50ppm/°C temperature coefficient, and ROHS3 compliance. Electrical substitution is valid. Physical dimensions differ; verify PCB layout compatibility for axial component spacing.

Q: What is the difference between CMF553K3200FHEB and CMF553K3200FHEK?

A: Both parts are electrically identical. The primary differences are packaging format (Cut Tape vs. Bulk) and REACH compliance status. CMF553K3200FHEB is REACH Unaffected; CMF553K3200FHEK is REACH Affected. Select based on supply chain and regulatory requirements.

Q: Are the physical dimensions compatible with existing PCB designs?

A: The RNF12FTC3K32 measures 0.108" diameter x 0.344" length. The CMF substitutes measure 0.090" diameter x 0.240" length. Both are axial through-hole components and fit standard 0.1" pitch hole spacing. Verify clearance requirements for component body diameter and lead spacing in your specific layout.

Q: Do the substitute parts offer any additional features?

A: CMF553K3200FHEB and CMF553K3200FHEK include moisture-resistant properties in addition to flame retardant coating. Both support extended operating temperature range to 175°C compared to the original 155°C maximum.

Q: What packaging options are available for substitutes?

A: CMF553K3200FHEB is available in Cut Tape (CT) format. CMF553K3200FHEK is available in Bulk format. The original RNF12FTC3K32 is supplied in Tape & Reel (TR) format. Select packaging based on assembly process requirements and order quantities.
