Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT20K0 is determined by the following core parameters: 20kΩ resistance value, 4-resistor isolated configuration, 8-pin count, 1206 (3216 Metric) package with convex long-side terminals, and surface mount technology. All identified substitutes maintain these fundamental electrical and mechanical specifications.

Substitute parts are categorized by performance tier based on tolerance and temperature coefficient:

Tier 1 - Enhanced Precision: ACASA2002E2002P100 and ACASA2002E2002P1AT offer improved tolerance (±0.25%) and superior temperature stability (±25ppm/°C) compared to the main part. ACASA2002E2002P1AT additionally provides increased power rating (125mW per element) and maintains automotive qualification (AEC-Q200) with extended temperature range (-55°C to 155°C).

Tier 2 - Professional Grade: ACASA200222002P100 provides intermediate tolerance (±0.5%) and temperature coefficient (±50ppm/°C) with professional-series specifications.

Tier 3 - Direct Equivalent: CAY16-2002F4LF by Bourns Inc. matches the main part's tolerance (±1%) and temperature coefficient (±200ppm/°C) with identical package dimensions, though with reduced power rating (62.5mW per element) and narrower operating temperature range (-55°C to 125°C).

Engineering Selection Recommendations

For Automotive Applications with Extended Temperature Requirements: ACASA2002E2002P1AT is the preferred substitute when designs require operation across the full -55°C to 155°C range. This part maintains AEC-Q200 automotive qualification matching the RAVF164DFT20K0, offers superior tolerance (±0.25%) and temperature stability (±25ppm/°C), and provides increased power dissipation capability (125mW per element). However, this part carries "Not For New Designs" status; use only for legacy design continuity or when existing qualification data supports its application.

For Active Production with Enhanced Precision: ACASA2002E2002P100 is suitable for new designs requiring improved tolerance and temperature coefficient performance. This part is actively produced, ROHS3 compliant, and offers ±0.25% tolerance with ±25ppm/°C temperature coefficient. The operating temperature range is limited to -55°C to 125°C; applications requiring 155°C operation must use ACASA2002E2002P1AT or the original RAVF164DFT20K0.

For Professional-Grade Applications: ACASA200222002P100 provides intermediate performance with ±0.5% tolerance and ±50ppm/°C temperature coefficient, suitable for voltage divider applications requiring TCR matching. Operating temperature range is -55°C to 125°C.

For Direct Equivalent Substitution: CAY16-2002F4LF by Bourns Inc. maintains identical tolerance (±1%) and temperature coefficient (±200ppm/°C) specifications. This part is actively produced with high inventory availability (20,759 units). The reduced power rating (62.5mW per element versus 100mW) and narrower operating temperature range (-55°C to 125°C) must be evaluated against circuit requirements. This part is not automotive-qualified and lacks AEC-Q200 certification.

Frequently Asked Questions (FAQ)

Q: Can ACASA2002E2002P1AT be used in new automotive designs? A: ACASA2002E2002P1AT carries "Not For New Designs" status. For new automotive applications requiring AEC-Q200 qualification and -55°C to 155°C operation, use RAVF164DFT20K0 or evaluate alternative active-status parts. ACASA2002E2002P100 is active but limited to -55°C to 125°C.

Q: What is the impact of reduced power rating in CAY16-2002F4LF? A: CAY16-2002F4LF provides 62.5mW per element versus 100mW in RAVF164DFT20K0. Circuit designs must ensure power dissipation does not exceed this limit. This part is suitable for low-power applications but not for designs requiring the full 100mW capability.

Q: Are all substitutes pin-compatible with RAVF164DFT20K0? A: All identified substitutes maintain 8-pin configuration in 1206 (3216 Metric) package with convex long-side terminals. Physical footprint compatibility is confirmed. Electrical compatibility depends on tolerance, temperature coefficient, and power requirements of the specific application.

Q: Which substitute offers the best temperature stability? A: ACASA2002E2002P100 and ACASA2002E2002P1AT both provide ±25ppm/°C temperature coefficient, superior to RAVF164DFT20K0 (±200ppm/°C) and CAY16-2002F4LF (±200ppm/°C). ACASA2002E2002P1AT additionally maintains automotive qualification and extended temperature range.

Q: What is the difference between ACASA2002E2002P100 and ACASA2002E2002P1AT? A: Both parts offer identical tolerance (±0.25%) and temperature coefficient (±25ppm/°C). ACASA2002E2002P1AT provides higher power per element (125mW versus 100mW), extended operating temperature range (-55°C to 155°C versus -55°C to 125°C), and maintains AEC-Q200 automotive qualification. ACASA2002E2002P1AT is marked "Not For New Designs."

Q: Is RoHS3 compliance maintained across all substitutes? A: All identified substitutes are ROHS3 compliant, matching the RAVF164DFT20K0 environmental compliance status.
