RC3225F1692CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F1692CS is a 16.9 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 with full RoHS3 compliance and MSL Level 1 rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowable parameter tolerances for this resistor category. Substitution becomes necessary in scenarios involving component availability, supply chain optimization, or design flexibility while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F1692CS is determined by strict alignment of the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 16.9 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (minimum requirement)

Mechanical Compatibility Requirements:

• Package format: 1210 (3225 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• MSL Level 1 (Unlimited) (mandatory)

Power Rating Consideration: Substitute parts may exceed the 0.333W rating of the main part. Higher power ratings (0.5W, 1/2W) are acceptable as they represent increased thermal capability without affecting electrical performance at the specified operating conditions.

The identified substitutes CRCW121016K9FKEA and ERJ-14NF1692U meet all electrical and mechanical equivalence criteria while providing enhanced power dissipation capability.

Parameter Comparison

Engineering Selection Recommendations

CRCW121016K9FKEA (Vishay Dale) is the primary substitute option. This part maintains full electrical equivalence with the RC3225F1692CS while providing increased power dissipation at 0.5W. The component carries Active product status, ensuring continued availability and manufacturing support. AEC-Q200 automotive qualification provides additional reliability assurance. Dimensional compatibility is confirmed with marginal height reduction (0.60mm vs. 0.66mm), which presents no mechanical constraint in standard PCB assembly applications.

ERJ-14NF1692U (Panasonic Electronic Components) is a secondary substitute option. Electrical specifications are identical to the primary substitute, with equivalent RoHS3 and MSL Level 1 compliance. However, this part carries "Not For New Designs" product status, indicating discontinued development support. The seated height of 0.70mm exceeds the main part specification by 0.04mm, which remains within typical PCB assembly tolerances. This part is suitable for replacement or repair applications where existing inventory exists.

Selection between substitutes should prioritize CRCW121016K9FKEA for new designs and ongoing production due to Active status and AEC-Q200 qualification. ERJ-14NF1692U remains functionally compatible for legacy system maintenance where supply continuity is established.

Frequently Asked Questions (FAQ)

Q: Can CRCW121016K9FKEA replace RC3225F1692CS in all applications?

A: Yes. Both parts share identical resistance (16.9 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The 1210 package format and thick film composition are identical. The higher power rating (0.5W vs. 0.333W) of CRCW121016K9FKEA represents increased thermal capability and does not restrict functionality in circuits designed for the lower rating.

Q: What is the significance of the power rating difference?

A: Power rating indicates maximum continuous power dissipation capability. A substitute with higher power rating (0.5W) can safely operate in applications designed for lower power (0.333W). The actual power dissipation in the circuit is determined by resistance and applied voltage, not by the component's rated capacity. Higher-rated components provide thermal margin without affecting electrical performance.

Q: Are there dimensional compatibility concerns with the substitute parts?

A: Dimensional variations are minimal and within standard PCB assembly tolerances. CRCW121016K9FKEA measures 3.20mm L x 2.50mm W with 0.60mm maximum seated height, compared to RC3225F1692CS at 3.20mm L x 2.55mm W with 0.66mm height. ERJ-14NF1692U measures 3.20mm L x 2.50mm W with 0.70mm height. These differences do not affect footprint compatibility or assembly processes.

Q: Why is ERJ-14NF1692U marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and marketing of this part number. While the component remains functionally equivalent and available in inventory, it is not recommended for new product designs. CRCW121016K9FKEA is the preferred substitute for new applications.

Q: Do all parts meet the same compliance standards?

A: Yes. RC3225F1692CS, CRCW121016K9FKEA, and ERJ-14NF1692U are all ROHS3 Compliant with MSL Level 1 (Unlimited) rating and REACH Unaffected status. CRCW121016K9FKEA carries additional AEC-Q200 automotive qualification.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts use the 1210 (3225 Metric) package with identical footprint requirements. Mechanical and electrical compatibility is confirmed. Assembly processes require no modification.
