Substitute Part Grouping Explanation

Substitute parts for the RC1005F2613CS are classified based on strict electrical and mechanical parameter alignment:

Direct Equivalent Classification: Parts that match all critical parameters including resistance value (261 kOhms), tolerance (±1%), power rating (0.063W / 1/16W), package format (0402), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL Level 1).

Upgrade Classification: Parts that maintain identical electrical specifications and package compatibility but feature enhanced power rating (0.1W / 1/10W) or additional automotive qualification (AEC-Q200). These parts are physically and electrically compatible with higher performance margins.

Similar Classification: Parts that match all core electrical and mechanical parameters but include additional automotive-grade certifications (AEC-Q200) or enhanced environmental features. These maintain full substitution compatibility while offering extended qualification scope.

The following parameters determine substitution eligibility:

Resistance value: 261 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Package: 0402 (1005 Metric) (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature: -55°C ~ 155°C (exact match required)
Composition: Thick film (exact match required)
Power rating: 0.063W minimum (equal or higher acceptable)

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07261KL be used as a direct replacement for RC1005F2613CS?

A: Yes. RC0402FR-07261KL is a direct equivalent with matching resistance (261 kOhms), tolerance (±1%), power rating (0.063W), package format (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Both parts carry ROHS3 compliance and MSL Level 1 rating.

Q: What is the difference between the main part and ERJ-2RKF2613X?

A: The primary difference is power rating. ERJ-2RKF2613X is rated at 0.1W (1/10W) compared to RC1005F2613CS at 0.063W (1/16W). ERJ-2RKF2613X also includes automotive AEC-Q200 qualification. All other electrical and mechanical parameters remain identical. The higher power rating provides additional thermal margin in the same 0402 package.

Q: Are automotive-qualified parts (AEC-Q200) compatible with non-automotive applications?

A: Yes. Automotive-qualified parts such as AC0402FR-07261KL, CRCW0402261KFKED, and RMCF0402FT261K meet or exceed industrial-grade specifications. They maintain identical electrical parameters and package compatibility. Automotive qualification represents additional testing and reliability certification, not a restriction on use.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All listed substitute parts use the 0402 (1005 Metric) package format with identical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). Physical PCB footprints are interchangeable.

Q: What does MSL Level 1 mean for these resistors?

A: MSL (Moisture Sensitivity Level) Level 1 indicates Unlimited shelf life. These parts do not require special moisture-controlled storage conditions and can be stored under standard industrial conditions without time-based degradation from moisture exposure.

Q: Can I substitute a higher power-rated part in a circuit designed for 0.063W?

A: Yes. Substituting a higher power-rated component (such as ERJ-2RKF2613X at 0.1W) in a circuit designed for 0.063W is electrically and mechanically compatible. The higher power rating provides additional thermal margin without affecting circuit performance. The component will operate at lower stress levels.

Q: Are there any height differences between substitute parts?

A: AC0402FR-07261KL has a maximum seated height of 0.015" (0.37mm), while all other parts including RC1005F2613CS are specified at 0.016" (0.40mm). This 0.001" (0.03mm) difference is within standard PCB assembly tolerances and does not affect interchangeability.
