Substitute Part Grouping Explanation

Substitute parts are grouped into three categories based on allowed parameter variations:

Category 1: Direct Equivalents (Identical Electrical & Environmental Specifications) Parts matching 2.2 kOhms ±1%, 0.125W power rating, 0805 package, AEC-Q200 automotive qualification, and ROHS3 compliance. These parts are interchangeable without circuit redesign.

Category 2: Tolerance Upgrades (Tighter Tolerance) Parts with 2.2 kOhms ±0.5% tolerance instead of ±1%, maintaining all other specifications. These provide improved accuracy and are backward compatible.

Category 3: Power Rating Upgrades (Higher Power Dissipation) Parts rated for 0.5W (1/2W) instead of 0.125W, maintaining 2.2 kOhms ±1%, 0805 package, and AEC-Q200 qualification. These provide thermal margin for high-stress applications.

Engineering Selection Recommendations

For Direct Substitution (No Circuit Redesign Required):

AC0805FR-072K2L (YAGEO) is the primary equivalent, offering identical electrical specifications, AEC-Q200 automotive qualification, and ROHS3 compliance with significantly higher inventory availability (104,169 units). The moisture-resistant feature provides equivalent environmental protection to the anti-sulfur coating of the original part.

ERJ-S06F2201V (Panasonic Electronic Components) provides an alternative direct equivalent with anti-sulfur coating matching the original part's environmental specification, AEC-Q200 qualification, and ROHS3 compliance.

CRCW08052K20FKEA (Vishay Dale) and CRCW08052K20FKTA (Vishay Dale) are direct electrical equivalents with AEC-Q200 qualification. CRCW08052K20FKEA maintains ROHS3 compliance; CRCW08052K20FKTA does not and should be avoided for new designs requiring RoHS compliance.

For Tolerance-Critical Applications:

RC0805DR-072K2L (YAGEO) provides ±0.5% tolerance for applications requiring tighter resistance accuracy. This part lacks AEC-Q200 automotive qualification and should be used only in non-automotive applications where the tighter tolerance is essential.

For High-Stress Thermal Applications:

CRCW08052K20FKEAHP (Vishay Dale), ERJ-UP6F2201V (Panasonic Electronic Components), and RCS08052K20FKEA (Vishay Dale) are rated for 0.5W (1/2W) power dissipation. These parts maintain 2.2 kOhms ±1%, 0805 package, AEC-Q200 qualification, and ROHS3 compliance. Selection among these three depends on packaging requirements (Cut Tape vs. Tape & Reel) and feature preferences (pulse withstanding capability).

Frequently Asked Questions (FAQ)

Q: Can I use AC0805FR-072K2L as a direct replacement for AF0805FR-072K2L?

A: Yes. Both parts share identical electrical specifications (2.2 kOhms ±1%, 0.125W), 0805 package, operating temperature range (-55°C to 155°C), AEC-Q200 automotive qualification, and ROHS3 compliance. The AC series uses moisture-resistant coating instead of anti-sulfur coating, providing equivalent environmental protection for most applications.

Q: What is the difference between the 0.125W and 0.5W rated parts?

A: Power rating indicates maximum continuous power dissipation. The 0.125W parts (AF0805FR-072K2L, AC0805FR-072K2L, CRCW08052K20FKEA, ERJ-S06F2201V) are suitable for standard circuit applications. The 0.5W parts (CRCW08052K20FKEAHP, ERJ-UP6F2201V, RCS08052K20FKEA) provide thermal margin for high-current or high-stress applications. Both maintain identical resistance value and tolerance.

Q: Why do some parts show RoHS non-compliance?

A: CRCW08052K20FKTA is marked RoHS non-compliant. This part should not be used in new designs or applications requiring RoHS3 compliance. Use CRCW08052K20FKEA (RoHS3 compliant) instead.

Q: Does tolerance affect circuit performance?

A: Tolerance specifies the maximum deviation from the nominal 2.2 kOhms value. The ±1% tolerance (most parts) allows ±22 ohms deviation. The ±0.5% tolerance (RC0805DR-072K2L) allows ±11 ohms deviation. Use tighter tolerance only if circuit design requires it; standard ±1% tolerance is sufficient for most applications.

Q: Are all substitute parts available in the same packaging?

A: No. Packaging varies: AF0805FR-072K2L, AC0805FR-072K2L, CRCW08052K20FKTA, ERJ-S06F2201V, ERJ-UP6F2201V, and RCS08052K20FKEA are supplied in Tape & Reel (TR). RC0805DR-072K2L, RC0805FR-072K2L, CRCW08052K20FKEA, and ERJ-6ENF2201V are supplied in Cut Tape (CT) & Digi-Reel. Verify packaging compatibility with your assembly process before selection.

Q: Which substitute offers the best inventory availability?

A: RC0805FR-072K2L (YAGEO) has the highest inventory at 1,037,008 units. AC0805FR-072K2L (YAGEO) offers 104,169 units with full AEC-Q200 qualification and ROHS3 compliance, making it the preferred high-availability equivalent.
