RC3225F3402CS Equivalent & Substitute Parts

Part Overview

The RC3225F3402CS is a 34 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) power dissipation in a 1210 (3225 Metric) surface mount package. This component is classified as Active product status and is RoHS3 compliant with MSL 1 moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. The primary substitute listed is the ERJ-14NF3402U from Panasonic Electronic Components, which shares the same resistance value, tolerance, package size, and operating temperature range while offering increased power rating and automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F3402CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 34 kOhms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2

Allowable Variation Parameters:

• Power Rating: Substitute may equal or exceed the 0.333W specification
• RoHS Status: Must maintain ROHS3 compliance or equivalent
• Moisture Sensitivity Level: Must be MSL 1 or lower
• Product Status: Active or Not For New Designs both acceptable for substitution purposes

The ERJ-14NF3402U meets all mandatory parameters and exceeds the power rating specification at 0.5W (1/2W), providing additional thermal margin. Both components share identical resistance, tolerance, package dimensions, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

RC3225F3402CS (Samsung Electro-Mechanics):

• Active product status ensures continued availability and manufacturing support
• Suitable for new designs and production applications
• Standard industrial-grade thick film resistor with MSL 1 rating
• 0.333W power rating appropriate for standard signal-level circuit applications

ERJ-14NF3402U (Panasonic Electronic Components):

• Not For New Designs status indicates phase-out trajectory; use only for legacy system maintenance or replacement applications
• Automotive AEC-Q200 qualification provides enhanced reliability documentation for mission-critical applications
• 0.5W power rating offers 50% additional thermal headroom compared to the main part
• Identical electrical and mechanical specifications ensure direct PCB footprint compatibility
• Higher power rating permits operation in higher-dissipation circuit environments without thermal derating

Selection between these parts depends on application requirements: the RC3225F3402CS is preferred for new designs, while the ERJ-14NF3402U serves as a qualified substitute for existing systems or applications requiring automotive-grade reliability documentation.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3402U directly replace RC3225F3402CS on existing PCBs?

A: Yes. Both components share identical 1210 (3225 Metric) package dimensions, footprint, and electrical specifications (34 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C). Dimensional variations (width 0.100" vs 0.098", height 0.026" vs 0.028") are within standard PCB assembly tolerances and do not affect placement or soldering.

Q: What is the significance of the higher 0.5W power rating on the ERJ-14NF3402U?

A: The increased power rating provides additional thermal margin. If circuit power dissipation approaches or exceeds 0.333W, the ERJ-14NF3402U maintains lower junction temperature and extends component lifetime. For applications operating below 0.333W, both parts perform identically.

Q: Why is ERJ-14NF3402U marked "Not For New Designs"?

A: This status indicates Panasonic has discontinued active promotion of this part number for new product development. Existing inventory remains available for legacy system support and replacement applications. New designs should prioritize the RC3225F3402CS or equivalent active-status alternatives.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 moisture sensitivity rating. The ERJ-14NF3402U includes AEC-Q200 automotive qualification, which is not specified for the RC3225F3402CS. This qualification is relevant only for automotive or mission-critical applications requiring documented reliability standards.

Q: What packaging formats are available?

A: RC3225F3402CS is supplied in standard packaging (format not specified in data). ERJ-14NF3402U is available in Tape & Reel (TR) format, suitable for automated assembly processes.
