Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F2260CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (226 Ohms), tolerance (±1%), and power rating (1W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Parameters: Package designation (2512 / 6432 metric) and number of terminations (2) define physical compatibility. Dimensional tolerances for length, width, and seated height must accommodate PCB layout and assembly processes.

Environmental & Compliance Parameters: Moisture Sensitivity Level 1 (Unlimited), RoHS3 compliance, and REACH unaffected status ensure regulatory and environmental compatibility.

Substitute parts are grouped into two categories: Upgrade substitutes (enhanced features such as automotive AEC-Q200 qualification) and Similar substitutes (equivalent specifications with alternative manufacturer sourcing).

Parameter Comparison

Engineering Selection Recommendations

For General Industrial Applications: The RC6432F2260CS (Samsung) remains the primary choice when bulk packaging is acceptable and cost optimization is prioritized. All three substitute parts provide electrical and mechanical equivalence.

For Automotive and High-Reliability Applications: AC2512FK-07226RL (YAGEO) and CRCW2512226RFKEG (Vishay Dale) are preferred substitutes due to AEC-Q200 automotive qualification. Both maintain Active product status and are suitable for new designs.

For Legacy System Maintenance: ERJ-1TNF2260U (Panasonic) provides functional equivalence but carries "Not For New Designs" status. This part is appropriate only for replacement in existing systems where design continuity is required.

Packaging Consideration: Substitute parts are supplied in Tape & Reel format, which differs from the bulk packaging of the main part. Verify that assembly equipment and procurement workflows accommodate this packaging format.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07226RL directly replace RC6432F2260CS in existing designs?

A: Yes. Both parts share identical electrical specifications (226 Ohms ±1%, 1W), composition (thick film), package (2512), and environmental ratings (MSL 1, ROHS3). The primary difference is AEC-Q200 automotive qualification in the YAGEO part and Tape & Reel packaging format.

Q: What is the significance of AEC-Q200 rating in substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. Parts bearing this rating have undergone additional reliability testing. For non-automotive applications, this certification provides enhanced confidence in component reliability but is not a functional requirement.

Q: Why is ERJ-1TNF2260U marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development of this product line. The part remains functionally equivalent and suitable for replacement in existing systems, but should not be selected for new circuit designs where alternative active products are available.

Q: Are dimensional variations between substitute parts significant?

A: Dimensional variations are within acceptable tolerances for the 2512 package class. Length ranges from 0.248" to 0.252" (6.30mm to 6.40mm), width from 0.122" to 0.126" (3.10mm to 3.20mm), and seated height from 0.026" to 0.028" (0.65mm to 0.70mm). These variations do not affect PCB layout or assembly compatibility.

Q: Does packaging format (bulk vs. Tape & Reel) affect component performance?

A: No. Packaging format affects only procurement, storage, and assembly logistics. Electrical and mechanical performance is identical regardless of packaging type.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts share the same operating temperature range (-55°C ~ 155°C) and temperature coefficient (±100ppm/°C), ensuring equivalent thermal performance across the specified range.
