Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F2672CS are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters:

• Resistance value: 26.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

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

Compliance Parameters:

• RoHS3 Compliant (required)
• REACH Unaffected (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)

Substitute parts identified in this reference are qualified when all electrical, mechanical, and compliance parameters match the main part specification. Power rating may exceed the original specification without affecting substitution validity, as higher power ratings provide design margin. Automotive AEC-Q200 qualification is an additional feature present in certain substitutes and does not preclude substitution for non-automotive applications.

Engineering Selection Recommendations

AC1210FR-0726K7L (YAGEO) - Upgrade Substitute: The AC1210FR-0726K7L is classified as an upgrade substitute due to increased power rating (0.5W versus 0.333W) and active product status. This part maintains all electrical specifications identical to the main part while providing enhanced thermal performance margin. AEC-Q200 automotive qualification is included, making this part suitable for both general-purpose and automotive applications. Dimensional variations are within typical manufacturing tolerances for the 1210 package class.

ERJ-14NF2672U (Panasonic Electronic Components) - Similar Substitute: The ERJ-14NF2672U meets all electrical and mechanical substitution criteria with identical resistance, tolerance, temperature coefficient, and operating temperature range. Power rating is increased to 0.5W, providing design margin. However, this part carries "Not For New Designs" product status, indicating Panasonic has discontinued active development. This part is suitable for legacy system maintenance, repair, and field replacement applications where existing inventory exists. New design implementations should prioritize the AC1210FR-0726K7L upgrade substitute.

Frequently Asked Questions (FAQ)

Q: Can the AC1210FR-0726K7L replace the RC3225F2672CS in all applications?

A: Yes. The AC1210FR-0726K7L is electrically and mechanically equivalent to the RC3225F2672CS. All critical parameters including resistance value, tolerance, temperature coefficient, operating temperature range, and package format are identical. The increased power rating (0.5W versus 0.333W) provides additional thermal margin and does not restrict substitution. Dimensional variations are within acceptable tolerances for the 1210 package class.

Q: What is the difference between the upgrade and similar substitute classifications?

A: The AC1210FR-0726K7L is classified as an upgrade substitute because it maintains Active product status with manufacturer ongoing support and development. The ERJ-14NF2672U is classified as a similar substitute because it carries "Not For New Designs" status, indicating the manufacturer has discontinued active development. Both parts are electrically and mechanically equivalent; the classification reflects product lifecycle status and supply chain continuity.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 1210 package class specification. The RC3225F2672CS measures 0.126" L x 0.100" W with 0.026" maximum seated height. The AC1210FR-0726K7L measures 0.122" L x 0.102" W with 0.024" maximum seated height. The ERJ-14NF2672U measures 0.126" L x 0.098" W with 0.028" maximum seated height. These variations are within standard manufacturing tolerances for the 1210 (3225 Metric) package and do not affect PCB layout compatibility or electrical performance.

Q: Does AEC-Q200 automotive qualification affect substitution for non-automotive applications?

A: No. AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive applications. Parts with automotive qualification meet or exceed general-purpose reliability standards and are fully compatible with non-automotive designs. The presence of AEC-Q200 qualification on the AC1210FR-0726K7L and ERJ-14NF2672U provides additional assurance of quality and reliability.

Q: What is the significance of Moisture Sensitivity Level 1 (Unlimited)?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly. Standard PCB assembly processes and storage conditions are acceptable without additional precautions or baking procedures.

Q: Can the ERJ-14NF2672U be used in new product designs?

A: The ERJ-14NF2672U carries "Not For New Designs" product status from Panasonic. This designation indicates the manufacturer has discontinued active development and support for this part. For new product designs, the AC1210FR-0726K7L is the recommended substitute, as it maintains Active product status with ongoing manufacturer support and supply chain continuity.
