RC3225F1691CS Equivalent & Substitute Parts

Part Overview

The RC3225F1691CS is a 1.69 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 and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with moisture resistant characteristics and ROHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility exist within the same package class, allowing for direct board-level replacement in applications where the original part becomes unavailable or when design requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F1691CS is determined by strict alignment with the following core parameters: identical resistance value (1.69 kOhms), matching tolerance specification (±1%), compatible package format (1210 / 3225 Metric), equivalent temperature coefficient (±100ppm/°C), and overlapping or superior operating temperature range (-55°C ~ 155°C). The substitute parts identified meet these electrical and mechanical criteria. Power rating substitution is permitted when the alternative component rating equals or exceeds the original specification, as higher power-rated components in the same package maintain thermal and dimensional compatibility. All identified substitutes maintain thick film composition, two-terminal configuration, and ROHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

CRCW12101K69FKEA (Vishay Dale) is the primary substitute option. This component maintains active production status, meets all electrical parameter requirements, and provides a higher power rating (0.5W versus 0.333W) within the identical 1210 package footprint. The increased power rating offers thermal margin without dimensional or mechanical incompatibility. Automotive AEC-Q200 qualification provides additional reliability assurance for demanding applications.

ERJ-14NF1691U (Panasonic Electronic Components) is a secondary substitute option. While this part meets all core electrical and mechanical specifications, it carries a "Not For New Designs" product status designation. This classification indicates the manufacturer is phasing out this component line. Selection of this part is appropriate only for legacy system maintenance, repair, or continuation of existing production runs where design changes are not feasible. The higher seated height (0.028" versus 0.026" for the main part) requires verification of available PCB clearance in height-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW12101K69FKEA be used as a direct replacement for RC3225F1691CS?

A: Yes. Both components share identical resistance (1.69 kOhms), tolerance (±1%), package format (1210), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The CRCW12101K69FKEA provides a higher power rating (0.5W versus 0.333W), which is compatible with the original application. Dimensional differences are minimal and do not affect PCB layout compatibility.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF1691U?

A: This designation indicates that Panasonic has discontinued active development and is transitioning away from this product line. While the part remains functionally equivalent and available in inventory, it should not be selected for new product designs. This part is suitable only for sustaining production of existing designs or repair applications where component replacement is necessary.

Q: Are there dimensional differences between the substitute parts and the main part?

A: Minor dimensional variations exist. The RC3225F1691CS has a maximum seated height of 0.026" (0.66mm), while CRCW12101K69FKEA measures 0.024" (0.60mm) and ERJ-14NF1691U measures 0.028" (0.70mm). Length and width specifications remain consistent at 0.126" L x 0.098-0.100" W across all parts. These variations are within standard 1210 package tolerances and do not affect standard PCB assembly processes.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All identified substitutes are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture Sensitivity Level remains at 1 (Unlimited) for all parts. The CRCW12101K69FKEA and ERJ-14NF1691U additionally carry AEC-Q200 automotive qualification, which exceeds the original part's certification level.

Q: What packaging formats are available for the substitute parts?

A: Both CRCW12101K69FKEA and ERJ-14NF1691U are supplied in Tape & Reel (TR) format, which differs from the main part's packaging specification. Tape & Reel format is standard for high-volume SMD assembly operations and is compatible with automated pick-and-place equipment. Verify that your procurement and assembly processes support this packaging format.
