RC3225F82R5CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F82R5CS is a 82.5 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format with 0.333W power rating. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). The part is designed for applications requiring precision resistive elements with moisture resistance in compact surface-mount configurations.

Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, composition) and mechanical compatibility (package format, termination count) while accounting for variations in power rating and application-specific certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F82R5CS is determined by the following mandatory parameters:

Critical Matching Parameters:

• Resistance value: 82.5 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package format: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Allowable Variation Parameters:

• Power rating: Substitute parts may have equal or higher power rating (0.5W acceptable as upgrade)
• Application certifications: Automotive AEC-Q200 certification is allowable addition
• Packaging format: Tape & Reel (TR) acceptable for substitute parts
• Moisture sensitivity level: MSL 1 maintained across all substitutes

The identified substitute parts CRCW121082R5FKEA and ERJ-14NF82R5U meet all critical matching parameters while featuring increased power rating (0.5W) and automotive-grade certifications, making them suitable for applications where the original part is unavailable or where enhanced power dissipation capability is beneficial.

Parameter Comparison

Engineering Selection Recommendations

CRCW121082R5FKEA (Vishay Dale) is the primary substitute option. This part maintains Active product status, carries ROHS3 compliance, and provides automotive-grade AEC-Q200 certification. The increased power rating (0.5W versus 0.333W) offers enhanced thermal margin without affecting electrical performance. Dimensional compatibility is confirmed with minimal height variation (0.024" seated height). This part is suitable for new designs and production applications.

ERJ-14NF82R5U (Panasonic Electronic Components) is a secondary substitute option. While electrically and mechanically equivalent, this part carries "Not For New Designs" product status, indicating it is in end-of-life phase. The part remains available in inventory and maintains AEC-Q200 automotive certification and ROHS3 compliance. Use of this part is restricted to legacy system maintenance, repair, or applications where design freeze has been established. The seated height (0.028") is marginally higher than the primary substitute.

For new design implementations, CRCW121082R5FKEA is the recommended selection. For existing production lines or legacy system support, either substitute is electrically and mechanically compatible with the original RC3225F82R5CS specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW121082R5FKEA replace RC3225F82R5CS in existing designs?

A: Yes. Both parts share identical resistance (82.5 Ohms), tolerance (±1%), composition (thick film), package format (1210), and operating temperature range (-55°C ~ 155°C). The CRCW121082R5FKEA features higher power rating (0.5W versus 0.333W), which is an acceptable upgrade that does not affect circuit performance. Dimensional differences are within typical PCB layout tolerances.

Q: What is the difference between the two substitute parts?

A: CRCW121082R5FKEA (Vishay Dale) maintains Active product status and is approved for new designs. ERJ-14NF82R5U (Panasonic) carries "Not For New Designs" status, indicating end-of-life phase. Both parts are electrically identical and AEC-Q200 certified. Selection depends on design phase and production timeline requirements.

Q: Are there any height compatibility concerns?

A: Seated heights vary slightly: RC3225F82R5CS (0.026"), CRCW121082R5FKEA (0.024"), and ERJ-14NF82R5U (0.028"). These variations are within standard PCB assembly tolerances and do not require design modification. Verify clearance in applications with height-constrained layouts.

Q: Do all parts meet RoHS and environmental compliance?

A: Yes. RC3225F82R5CS, CRCW121082R5FKEA, and ERJ-14NF82R5U are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). All parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: Can ERJ-14NF82R5U be used in new production?

A: No. ERJ-14NF82R5U carries "Not For New Designs" product status. This part is suitable only for maintenance, repair, or legacy system support where design freeze has been established. For new production, use CRCW121082R5FKEA or the original RC3225F82R5CS.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive-grade qualification standard. Both substitute parts carry this certification, indicating suitability for automotive applications with enhanced reliability requirements. The original RC3225F82R5CS does not carry this certification but features moisture resistance for general industrial applications.

Q: Are packaging format differences significant?

A: The original part is specified with standard packaging, while substitutes are supplied in Tape & Reel (TR) format. This is a supply chain variation that does not affect component performance or compatibility. TR packaging is standard for high-volume production environments.
