Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AC2010FK-0782KL are qualified based on the following criteria:

Electrical Parameters: Resistance value (82 kOhms), tolerance (±1%), power rating (0.75W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C) must be identical.

Mechanical Parameters: Package designation (2010/5025 Metric), physical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm), and number of terminations (2) must match.

Compliance & Certifications: AEC-Q200 automotive qualification and ROHS3 compliance are required. Moisture Sensitivity Level MSL 1 is maintained across all substitutes.

Packaging: All substitutes are supplied in Tape & Reel (TR) format consistent with the original part.

Two substitute parts meet these criteria: CRGCQ2010F82K (TE Connectivity Passive Product) and RMCF2010FT82K0 (Stackpole Electronics Inc).

Parameter Comparison

Engineering Selection Recommendations

All three parts—AC2010FK-0782KL, CRGCQ2010F82K, and RMCF2010FT82K0—are active production components with AEC-Q200 automotive qualification and ROHS3 compliance. They are electrically and mechanically equivalent for 82 kOhms ±1% 0.75W applications in the 2010 package.

The RMCF2010FT82K0 exhibits a maximum seated height of 0.028" (0.70mm) compared to 0.026" (0.65mm) for the other two parts. This 0.002" (0.05mm) difference is within typical PCB assembly tolerances but should be evaluated if height-constrained applications are involved.

All parts maintain identical electrical performance across the -55°C to 155°C operating range with ±100ppm/°C temperature coefficient and MSL 1 moisture sensitivity rating. Selection among these substitutes depends on availability, lead time, and supplier preference rather than technical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can CRGCQ2010F82K and RMCF2010FT82K0 be used interchangeably with AC2010FK-0782KL?

A: Yes. All three parts meet identical electrical specifications (82 kOhms ±1%, 0.75W, ±100ppm/°C) and mechanical requirements (2010 package, 5.00mm x 2.50mm). All carry AEC-Q200 qualification and ROHS3 compliance. The 0.002" height difference in the Stackpole part is negligible for most applications.

Q: Are there any package compatibility concerns?

A: No. All three parts use the 2010 (5025 Metric) package with identical land pattern dimensions (0.197" L x 0.098" W). They are directly compatible on the same PCB layout.

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

A: AEC-Q200 certification indicates the component meets automotive-grade reliability standards for temperature cycling, moisture resistance, and long-term stability. All three parts carry this qualification, making them suitable for automotive applications.

Q: Does moisture sensitivity affect component handling?

A: All three parts are rated MSL 1 (Unlimited), meaning they have unlimited shelf life and require no special moisture control during storage or handling. Standard ESD precautions apply.

Q: Are there differences in REACH compliance?

A: The AC2010FK-0782KL and RMCF2010FT82K0 are REACH Unaffected. The CRGCQ2010F82K shows Vendor Undefined REACH status. For applications requiring explicit REACH compliance documentation, the YAGEO or Stackpole parts are preferred.
