• Number of resistors: 4
• Circuit type: Isolated
• Tolerance: ±1%
• Temperature coefficient: ±200ppm/°C
• Package: 1206 (3216 Metric) surface mount
• Number of pins: 8
• Operating temperature range: -55°C minimum to 155°C maximum
• Automotive grade with AEC-Q200 qualification
• ROHS3 compliance

Secondary Compatibility Factors:

• Power per element rating (minimum 62.5mW required)

• Height variation within PCB assembly constraints

The substitute parts listed below meet all primary matching criteria and maintain compatibility with the original design specifications.

Parameter Comparison

Engineering Selection Recommendations

RAVF164DFT33K0 (Stackpole Electronics Inc): This part is the manufacturer-recommended substitute from Stackpole Electronics Inc. It maintains identical tolerance, temperature coefficient, and operating temperature range specifications. The resistance value of 33k Ohm falls within the ±1% tolerance band of the original 33.2k Ohm specification. The higher power per element rating (100mW vs. 62.5mW) provides additional thermal margin. The convex terminal configuration differs from the original concave design but maintains 1206 package compatibility. Product status is active with full AEC-Q200 automotive qualification.

742C0833322FP (CTS Resistor Products): This part provides exact resistance matching at 33.2k Ohm with identical power per element specification (63mW). It maintains all critical electrical parameters including tolerance, temperature coefficient, and pin configuration. The operating temperature range extends to 125°C maximum, which is 30°C lower than the original specification. This part is suitable for applications where the upper temperature limit does not exceed 125°C. Product status is active with AEC-Q200 qualification.

TC164-FR-0733K2L (YAGEO): This part provides exact resistance matching at 33.2k Ohm with identical power per element specification (62.5mW). All electrical parameters including tolerance, temperature coefficient, and operating temperature range (-55°C ~ 155°C) match the original specification. The package configuration is identical with concave terminals. Product status is active with AEC-Q200 automotive qualification.

All three substitute parts maintain ROHS3 compliance and MSL rating 1 (Unlimited) specifications.

Frequently Asked Questions (FAQ)

Q: Can RAVF164DFT33K0 be used as a direct replacement for RACF164DFT33K2?

A: RAVF164DFT33K0 is functionally compatible within the ±1% tolerance specification. The 33k Ohm resistance value differs from the original 33.2k Ohm by approximately 0.6%, which falls within the ±1% tolerance band. The higher power per element rating (100mW) provides additional thermal headroom. The convex terminal configuration differs from the original concave design but maintains electrical and mechanical compatibility within the 1206 package footprint. Verify PCB layout clearances if terminal height differences are critical to your assembly process.

Q: What is the difference between concave and convex terminal configurations?

A: Concave terminals are recessed into the package body, while convex terminals protrude outward. Both configurations maintain the same 1206 (3216 Metric) footprint and pin spacing. The height difference (0.030" for RACF164DFT33K2 vs. 0.024" for RAVF164DFT33K0) may affect PCB assembly clearances in space-constrained designs. Verify your PCB design rules and reflow oven profile compatibility before substitution.

Q: Why does 742C0833322FP have a lower maximum operating temperature?

A: The 742C0833322FP from CTS Resistor Products specifies a maximum operating temperature of 125°C, compared to 155°C for the original RACF164DFT33K2. This part is suitable for applications where the maximum ambient or component temperature does not exceed 125°C. For designs requiring the full -55°C ~ 155°C temperature range, select TC164-FR-0733K2L or RAVF164DFT33K0.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All three substitute parts (RAVF164DFT33K0, 742C0833322FP, and TC164-FR-0733K2L) carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification.

Q: What is the significance of the ±1% tolerance specification?

A: The ±1% tolerance indicates that the actual resistance value will be within ±1% of the nominal value. For a 33.2k Ohm resistor, this means the actual value will be between 32.868k Ohm and 34.632k Ohm. The 33k Ohm value of RAVF164DFT33K0 (range: 32.67k ~ 33.33k Ohm) overlaps with this specification and is functionally equivalent for circuit design purposes.

Q: Are all parts ROHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and MSL rating 1 (Unlimited), matching the environmental and regulatory requirements of the original RACF164DFT33K2.
