Substitute Part Grouping Explanation

Substitute parts for the RC3225F1820CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 182 Ohms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 1210 (3225 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

Power Rating Consideration: Substitute parts with equal or higher power ratings (0.333W or greater) are acceptable. Higher power ratings provide equivalent or improved thermal performance in the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

AC1210FR-07182RL (YAGEO) - Upgrade Substitute: This part qualifies as an upgrade substitute. It maintains all electrical and mechanical specifications of the RC3225F1820CS while providing increased power dissipation capability (0.5W vs. 0.333W) in the identical 1210 package. The AC1210FR-07182RL carries AEC-Q200 automotive qualification and active product status, making it suitable for new designs and applications requiring enhanced thermal margin.

ERJ-14NF1820U (Panasonic) - Similar Substitute: This part meets all electrical and mechanical requirements and carries AEC-Q200 automotive qualification. However, its product status is listed as "Not For New Designs," restricting its use to legacy system support or replacement applications only. The ERJ-14NF1820U is suitable for direct substitution in existing designs but should not be selected for new circuit development.

Selection Priority: For new designs, AC1210FR-07182RL is the preferred substitute. For legacy system maintenance, ERJ-14NF1820U provides functional equivalence with the same electrical performance.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-07182RL replace RC3225F1820CS in all applications? A: Yes. The AC1210FR-07182RL maintains identical resistance, tolerance, temperature coefficient, and operating range. The higher power rating (0.5W vs. 0.333W) provides equal or improved performance in the same 1210 package footprint.

Q: What is the difference between "Upgrade" and "Similar" substitute classifications? A: AC1210FR-07182RL is classified as an upgrade substitute because it is in active production status with enhanced specifications (higher power rating and AEC-Q200 qualification). ERJ-14NF1820U is classified as similar because it meets electrical and mechanical requirements but carries a "Not For New Designs" status, limiting its application to legacy system support.

Q: Are dimensional differences between these parts significant? A: Dimensional variations are within acceptable tolerances for 1210 package components. All three parts share the same 1210 (3225 Metric) package designation and 2-termination configuration, ensuring mechanical compatibility on standard PCB layouts.

Q: Does the higher power rating of substitute parts affect circuit performance? A: No. Higher power ratings indicate improved thermal capability without changing electrical behavior. The 182 Ohm resistance, ±1% tolerance, and temperature coefficient remain identical across all three parts.

Q: Are all three parts RoHS3 compliant? A: Yes. RC3225F1820CS, AC1210FR-07182RL, and ERJ-14NF1820U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: Which part should be selected for automotive applications? A: AC1210FR-07182RL is recommended for automotive applications due to active production status and AEC-Q200 qualification. ERJ-14NF1820U also carries AEC-Q200 qualification but is restricted from new designs.
