RC3225F6193CS Equivalent & Substitute Parts

Part Overview

The RC3225F6193CS is a 619 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and carries ROHS3 compliance certification.

Substitute parts become necessary when the primary component experiences supply constraints, inventory limitations, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications. The RC3225F6193CS has documented substitute availability through Panasonic Electronic Components and other manufacturers offering compatible 619 kOhms resistors in the same package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F6193CS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance value: 619 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package format: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (minimum requirement)
• Moisture Sensitivity Level: MSL 1 (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may equal or exceed the 0.333W specification
• RoHS Status: Substitutes may differ in compliance level based on application requirements
• Manufacturer: Different manufacturers permitted provided all critical parameters match
• Product Status: Active or Not For New Designs status does not preclude substitution eligibility

The ERJ-14NF6193U from Panasonic Electronic Components qualifies as a direct substitute based on matching all critical parameters while providing an increased power rating of 0.5W (1/2W), which exceeds the original specification and provides additional thermal margin.

Engineering Selection Recommendations

RC3225F6193CS Selection Criteria: The RC3225F6193CS remains the primary choice for applications requiring ROHS3 compliance and Active product status with ongoing manufacturer support. This component is suitable for standard commercial and industrial applications where RoHS3 certification is a mandatory requirement.

ERJ-14NF6193U Selection Criteria: The ERJ-14NF6193U from Panasonic qualifies as an electrical and mechanical substitute when the following conditions are met:

1. RoHS compliance requirements permit non-compliant alternatives or when RoHS3 compliance is not mandated
2. Automotive-grade reliability (AEC-Q200) is beneficial or required for the application
3. The increased power rating of 0.5W provides thermal design margin for the circuit
4. Supply chain constraints on the RC3225F6193CS necessitate alternative sourcing

The ERJ-14NF6193U carries "Not For New Designs" status from Panasonic, indicating this component is available for existing design support and replacement applications but is not recommended for new product development initiatives.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF6193U directly replace the RC3225F6193CS in existing designs?

A: Yes, the ERJ-14NF6193U meets all critical electrical and mechanical parameters. The 1210 package format, 619 kOhms resistance value, ±1% tolerance, ±100ppm/°C temperature coefficient, and MSL 1 rating are identical. The increased power rating (0.5W vs. 0.333W) provides additional thermal capacity. However, RoHS compliance status differs; verify your application requirements before substitution.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF6193U?

A: This designation indicates Panasonic continues to supply the ERJ-14NF6193U for existing applications and replacement purposes but does not recommend this component for new product development. The part remains electrically and mechanically valid for substitution in established designs.

Q: Are there dimensional differences between these two resistors?

A: Both components use the 1210 (3225 Metric) package format. Minor dimensional variations exist: RC3225F6193CS measures 0.126" L x 0.100" W with 0.026" maximum seated height, while ERJ-14NF6193U measures 0.126" L x 0.098" W with 0.028" maximum seated height. These differences fall within standard PCB layout tolerances for 1210 components.

Q: Does the higher power rating of the ERJ-14NF6193U affect circuit performance?

A: No. The power rating represents maximum dissipation capability. If the circuit design requires only 0.333W dissipation, the ERJ-14NF6193U will operate within its specifications. The higher rating provides thermal margin and does not alter electrical performance at the design operating point.

Q: What RoHS compliance applies to each component?

A: The RC3225F6193CS carries ROHS3 compliance certification. The ERJ-14NF6193U is RoHS non-compliant. Applications subject to RoHS3 regulatory requirements must use the RC3225F6193CS or identify alternative compliant substitutes.

Q: Can these resistors be used interchangeably in automated assembly?

A: Yes. Both components use identical 1210 package format and two-termination configuration. Tape & Reel packaging is available for both, supporting standard pick-and-place assembly processes. Verify feeder compatibility with your assembly equipment specifications.
