RC3225F1693CS Equivalent & Substitute Parts

Part Overview

The RC3225F1693CS is a 169 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 product status with 816 pieces available in new original inventory.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit the use of alternative manufacturers' components that meet or exceed the electrical and mechanical specifications of the original part.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F1693CS is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 169 kOhms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• RoHS3 Compliance

Allowable Variation:

• Power rating may be equal to or greater than 0.333W (1/3W)
• Physical dimensions may vary within standard 1210 package tolerances
• Moisture Sensitivity Level remains at 1 (Unlimited)

The ERJ-14NF1693U from Panasonic Electronic Components meets all mandatory parameters with an increased power rating of 0.5W (1/2W), making it a valid electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

The RC3225F1693CS remains the primary component choice due to its Active product status and current availability of 816 pieces in new original inventory.

The ERJ-14NF1693U from Panasonic serves as an electrical and mechanical equivalent with the following considerations:

Advantages of ERJ-14NF1693U:

• Higher power rating (0.5W vs. 0.333W) provides additional thermal margin
• AEC-Q200 automotive qualification for applications requiring automotive-grade components
• Larger inventory availability (10,693 pieces)

Limitations of ERJ-14NF1693U:

• Product status is "Not For New Designs," restricting use in new development programs
• Intended for legacy system support and replacement applications only

Selection between these components must align with program requirements regarding product lifecycle status and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1693U be used as a direct replacement for RC3225F1693CS in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both components share identical resistance (169 kOhms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The ERJ-14NF1693U has a higher power rating (0.5W vs. 0.333W), which is acceptable for substitution. However, the "Not For New Designs" status of the ERJ-14NF1693U restricts its use to replacement and legacy applications.

Q: What are the physical dimension differences between these parts?

A: Both components conform to the 1210 (3225 Metric) package standard. Length is identical at 0.126" (3.20mm). Width differs slightly: RC3225F1693CS is 0.100" (2.55mm) while ERJ-14NF1693U is 0.098" (2.50mm). Maximum seated height is 0.026" (0.66mm) for RC3225F1693CS and 0.028" (0.70mm) for ERJ-14NF1693U. These variations remain within standard 1210 package tolerances and do not affect PCB layout compatibility.

Q: Are both components RoHS3 compliant?

A: Yes, both RC3225F1693CS and ERJ-14NF1693U are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the significance of the AEC-Q200 rating on the ERJ-14NF1693U?

A: AEC-Q200 is an automotive qualification standard. The ERJ-14NF1693U meets this specification, making it suitable for automotive applications. The RC3225F1693CS does not carry this designation. Selection depends on whether the application requires automotive-grade components.

Q: Why is the ERJ-14NF1693U marked "Not For New Designs"?

A: This status indicates the component is in a mature or declining phase of its product lifecycle. Panasonic restricts its use to replacement and legacy applications. New product development should prioritize the RC3225F1693CS or other components with Active status.
