RC3225F1580CS Equivalent & Substitute Parts

Part Overview

The RC3225F1580CS is a 158 Ohm ±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 and is ROHS3 compliant with MSL 1 rating.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit higher power ratings or alternative certifications such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3225F1580CS is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 158 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package format: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variation Parameters:

• Power Rating: Equal to or greater than 0.333W
• Manufacturer: Different manufacturer permitted
• Product Status: Active or Not For New Designs
• Certifications: Additional certifications (such as AEC-Q200) permitted
• Packaging Format: Tape & Reel or alternative packaging permitted

The ERJ-14NF1580U from Panasonic Electronic Components qualifies as a substitute based on matching all critical parameters while providing a higher power rating of 0.5W (1/2W) and automotive AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

RC3225F1580CS Selection Criteria:

• Primary choice for new designs requiring active product status
• Suitable for general industrial and consumer applications
• Standard compliance profile with ROHS3 and MSL 1 rating
• Adequate power dissipation for applications requiring 0.333W or less

ERJ-14NF1580U Selection Criteria:

• Substitute when RC3225F1580CS availability is constrained
• Acceptable for applications where power dissipation does not exceed 0.5W
• Automotive AEC-Q200 certification provides additional qualification for automotive-grade applications
• Product status "Not For New Designs" indicates this part is in mature phase; use only when supply of primary part is unavailable
• Dimensional variation (height 0.028" vs 0.026") requires verification for space-constrained PCB layouts

Both parts maintain identical electrical performance at the 158 Ohm specification with ±1% tolerance and identical temperature characteristics. Selection between these parts should be based on availability, application requirements, and design phase status.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1580U directly replace RC3225F1580CS in existing designs?

A: Yes, for applications where the circuit design does not require the specific 0.333W power rating. The ERJ-14NF1580U provides 0.5W capability, which is a superset of the original specification. Verify PCB layout clearances due to the 0.002" (0.04mm) height difference.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF1580U?

A: This designation indicates the part is in mature production phase and may have extended lead times or eventual discontinuation. Use this part only as a substitute when the primary RC3225F1580CS is unavailable. For new product development, specify the RC3225F1580CS.

Q: Are the dimensional differences between these parts critical?

A: The length (0.126") and width dimensions are identical. The height difference is 0.002" (0.04mm), which is negligible for most applications. Verify clearance in designs with tight vertical constraints or high-density PCB layouts.

Q: Does the AEC-Q200 certification on the ERJ-14NF1580U affect compatibility?

A: No. AEC-Q200 is an additional qualification that does not restrict use in non-automotive applications. The part remains fully compatible with standard industrial and consumer designs.

Q: What packaging formats are available for these parts?

A: RC3225F1580CS is available in standard packaging. ERJ-14NF1580U is supplied in Tape & Reel (TR) format. Verify packaging compatibility with your procurement and assembly processes.

Q: Are there other substitute parts listed for the RC3225F1580CS?

A: The primary substitute documented is ERJ-14NF1580U. Additional substitutes for the ERJ-14NF1580U include CRCW1210158RFKTA, AF1210FR-07158RL, ERJ-P06F1580V, AC1210FR-07158RL, and CRCW1210158RFKEA. These represent further alternatives in the 158 Ohm 1210 package category.
