Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F1180CS is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 118 Ohms
• 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:

• Power Rating: Substitute parts may have equal or higher power ratings (0.333W or greater)
• Physical dimensions: Minor variations within supplier device package specifications are acceptable
• Compliance certifications: Substitute parts may include additional certifications (e.g., AEC-Q200)

The ERJ-14NF1180U from Panasonic Electronic Components qualifies as a substitute based on matching resistance, tolerance, package, composition, temperature coefficient, and operating temperature range. The ERJ-14NF1180U provides a higher power rating (0.5W vs. 0.333W), which is compatible with applications designed for the RC3225F1180CS.

Parameter Comparison

Engineering Selection Recommendations

RC3225F1180CS (Samsung Electro-Mechanics):

• Product Status: Active
• Recommended for new designs requiring Samsung component qualification
• Current inventory: 668 pieces
• Suitable for applications where 1/3W power rating is specified

ERJ-14NF1180U (Panasonic Electronic Components):

• Product Status: Not For New Designs
• Includes AEC-Q200 automotive qualification
• Higher power rating (0.5W) provides thermal margin in existing designs
• Current inventory: 25,060 pieces
• Suitable for retrofit or replacement applications where higher power dissipation capability is beneficial

Both parts meet ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on design qualification requirements and supply availability.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1180U replace RC3225F1180CS in existing designs?

A: Yes. The ERJ-14NF1180U matches all critical electrical parameters (118 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and package specifications (1210 / 3225 Metric). The higher power rating (0.5W vs. 0.333W) is compatible with applications designed for the RC3225F1180CS.

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

A: The RC3225F1180CS is rated at 0.333W (1/3W), while the ERJ-14NF1180U is rated at 0.5W (1/2W). A substitute with equal or higher power rating is acceptable for the same application. The higher rating in the substitute provides additional thermal margin without affecting electrical performance.

Q: Are there physical dimension differences between these parts?

A: Minor differences exist within supplier device package tolerances. RC3225F1180CS: 3.20mm x 2.55mm x 0.66mm (max height). ERJ-14NF1180U: 3.20mm x 2.50mm x 0.70mm (max height). Both conform to 1210 (3225 Metric) package specifications and are mechanically compatible in standard PCB layouts.

Q: What does "Not For New Designs" mean for the ERJ-14NF1180U?

A: This product status indicates Panasonic does not recommend the ERJ-14NF1180U for new design implementations. It remains available for replacement and retrofit applications. For new designs, the RC3225F1180CS (Active status) is the preferred choice.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC3225F1180CS and ERJ-14NF1180U are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures, simplifying supply chain management.
