Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RACF164DFT2K00 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 2kΩ
• Tolerance: ±1%
• Number of resistors: 4
• Circuit type: Isolated
• Temperature coefficient: ±200ppm/°C
• Package: 1206 (3216 Metric)
• Mounting type: Surface Mount

Secondary Compatibility Factors:

• Power per element rating (minimum 62.5mW required)
• Operating temperature range (minimum -55°C to 125°C required)
• RoHS and REACH compliance status
• Automotive grade and AEC-Q200 qualification

Substitute parts are grouped into two categories:

Category 1 - Direct Functional Equivalents (Identical Specifications): Parts matching all primary criteria with identical or superior power ratings and temperature ranges. These parts are fully interchangeable without circuit redesign.

Category 2 - Compatible Alternatives (Resistance Value Variance): Parts with different resistance values (20kΩ) that share the same package, isolation topology, and automotive qualification. These require circuit analysis to confirm suitability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

RAVF164DFT2K00, TC164-FR-072KL, and CAT16-2001F4LF are direct functional equivalents to the RACF164DFT2K00. All three parts maintain identical resistance values (2kΩ), tolerance (±1%), isolation topology, and automotive AEC-Q200 qualification. RAVF164DFT2K00 offers enhanced power rating (100mW vs 62.5mW) and maintains the full -55°C to 155°C operating range. TC164-FR-072KL and CAT16-2001F4LF provide equivalent performance with active product status and established supply chains. CAT16-2001F4LF demonstrates the highest inventory availability (13,444 units).

Secondary Alternative:

742C0832002FP (CTS Resistor Products) differs in resistance value (20kΩ vs 2kΩ) and is suitable only for applications where 20kΩ isolation networks are functionally acceptable. This part shares identical package geometry, isolation topology, automotive grade, and AEC-Q200 qualification. Operating temperature range is limited to -55°C to 125°C.

Selection Criteria:

• For direct replacement without circuit modification: RAVF164DFT2K00, TC164-FR-072KL, or CAT16-2001F4LF
• For enhanced power dissipation capability: RAVF164DFT2K00
• For maximum supply availability: CAT16-2001F4LF
• For extended temperature operation (-55°C to 155°C): RAVF164DFT2K00 or TC164-FR-072KL

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 rating, and automotive-grade specifications required for the original application.

Frequently Asked Questions (FAQ)

Q: Can RAVF164DFT2K00 replace RACF164DFT2K00 directly?

A: Yes. RAVF164DFT2K00 is a direct functional equivalent with identical electrical specifications (2kΩ, ±1%, 4 resistors, isolated topology). The higher power rating (100mW vs 62.5mW) provides additional design margin. The convex package profile differs from the concave RACF164DFT2K00, but both conform to 1206 (3216 Metric) dimensions and surface mount assembly requirements.

Q: What is the difference between concave and convex package profiles?

A: Concave and convex refer to the top surface geometry of the 1206 package. Both profiles maintain identical footprint dimensions (3.20mm × 1.60mm) and are compatible with standard PCB assembly equipment. Height differences (0.75mm concave vs 0.60mm convex for RAVF164DFT2K00) are within typical PCB clearance tolerances for automotive applications.

Q: Is TC164-FR-072KL suitable for applications requiring -55°C to 155°C operation?

A: Yes. TC164-FR-072KL operates across -55°C to 155°C, matching the RACF164DFT2K00 temperature range. All electrical parameters (2kΩ, ±1%, ±200ppm/°C) and automotive AEC-Q200 qualification are identical.

Q: Can 742C0832002FP be used as a substitute?

A: 742C0832002FP is not a direct substitute due to its 20kΩ resistance value versus the required 2kΩ. This part is suitable only for applications where 20kΩ isolation networks are functionally equivalent. Verify circuit requirements before selection.

Q: What is the significance of AEC-Q200 qualification?

A: AEC-Q200 qualification certifies that the resistor network meets automotive industry reliability and performance standards. All listed substitutes maintain this qualification, ensuring compatibility with automotive-grade applications and supply chain requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. RAVF164DFT2K00, TC164-FR-072KL, CAT16-2001F4LF, and 742C0832002FP are all ROHS3 compliant with MSL Level 1 (unlimited moisture sensitivity), matching the RACF164DFT2K00 environmental compliance profile.

Q: Which substitute offers the best supply availability?

A: CAT16-2001F4LF (Bourns Inc.) demonstrates the highest inventory level at 13,444 units. This part is a direct functional equivalent with active product status and established distribution channels.
