Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RACF164DFT4K02 is determined by the following critical parameters:

Direct Electrical Equivalence (Identical Specifications):

• Resistance value: 4.02kΩ
• Tolerance: ±1%
• Number of resistors: 4
• Circuit type: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Package footprint: 1206 (3216 Metric)
• Pin count: 8
• Mounting type: Surface Mount
• Automotive grade and AEC-Q200 qualification

Functional Equivalence (Acceptable Variations):

• Power per element: May increase from 62.5mW to higher ratings (backward compatible)
• Package terminal configuration: Concave or Convex acceptable (same footprint)
• Product status: Active preferred over Obsolete

The TC164-FR-074K02L (YAGEO) qualifies as a direct electrical equivalent, matching all critical parameters including resistance, tolerance, power rating, and package specifications. The RAVF164DFT4K30 (Stackpole Electronics Inc) qualifies as a functional equivalent with increased power per element (100mW) and slightly different resistance value (4.3kΩ), suitable where circuit design permits minor resistance tolerance adjustments.

Parameter Comparison

Engineering Selection Recommendations

TC164-FR-074K02L (YAGEO) - Recommended Primary Substitute: This part is the direct electrical equivalent to the RACF164DFT4K02. It maintains identical resistance value (4.02kΩ), tolerance (±1%), power per element (62.5mW), and package specifications. The TC164-FR-074K02L carries Active product status, ensuring long-term availability and supply chain continuity. Both parts hold AEC-Q200 automotive qualification and ROHS3 compliance. This substitute requires no circuit redesign and provides pin-for-pin compatibility.

RAVF164DFT4K30 (Stackpole Electronics Inc) - Alternative Substitute: This part offers functional equivalence with increased power per element (100mW) and remains within the same manufacturer family. The resistance value differs at 4.3kΩ, representing a 7% increase from the original 4.02kΩ specification. This substitute is suitable only for applications where circuit design permits minor resistance value adjustments or where the higher power rating provides additional thermal margin. The RAVF164DFT4K30 maintains Active product status, AEC-Q200 qualification, and ROHS3 compliance. Package terminal configuration differs (Convex vs. Concave) but maintains identical footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can TC164-FR-074K02L be used as a direct replacement for RACF164DFT4K02? A: Yes. The TC164-FR-074K02L is a direct electrical equivalent. All critical parameters match: 4.02kΩ resistance, ±1% tolerance, 62.5mW power per element, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, 1206 package, 8-pin configuration, and AEC-Q200 automotive qualification. No circuit modifications are required.

Q: What is the difference between the Concave and Convex terminal configurations? A: Both terminal configurations maintain the same 1206 (3216 Metric) footprint and are mechanically compatible with standard PCB layouts. The terminal shape difference does not affect electrical performance or mounting compatibility. Selection between Concave and Convex depends on existing PCB design specifications.

Q: Can RAVF164DFT4K30 replace RACF164DFT4K02 in all applications? A: The RAVF164DFT4K30 is a functional equivalent suitable only for applications where the 4.3kΩ resistance value (versus 4.02kΩ) is acceptable. The 7% resistance increase and higher power per element (100mW) may affect circuit performance in precision applications. Circuit validation is required before substitution.

Q: Are all substitute parts automotive-grade and AEC-Q200 qualified? A: Yes. Both TC164-FR-074K02L and RAVF164DFT4K30 carry automotive grade classification and AEC-Q200 qualification, matching the original RACF164DFT4K02 specification.

Q: What is the inventory status of these substitute parts? A: TC164-FR-074K02L has 1095 pieces in stock. RAVF164DFT4K30 has 886 pieces in stock. Both are available as new original components.

Q: Are all parts ROHS3 compliant? A: Yes. RACF164DFT4K02, TC164-FR-074K02L, and RAVF164DFT4K30 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
