Substitute Part Grouping Explanation

Substitution eligibility for the RACF164DFT5K11 is determined by the following critical parameters:

Direct Electrical Equivalence (Preferred): Parts must maintain identical resistance value (5.11k Ohm), tolerance (±1%), temperature coefficient (±200ppm/°C), and circuit topology (Isolated, 4-element array). The TC164-FR-075K11L from YAGEO meets all direct electrical specifications and package requirements.

Functional Equivalence (Alternative): Parts with equivalent electrical performance within the tolerance band and thermal characteristics may substitute if power rating and package form factor remain compatible. The RAVF164DFT5K10 from Stackpole Electronics Inc provides functional equivalence with a nominal resistance of 5.1k Ohm (within ±1% tolerance overlap) and enhanced power rating of 100mW per element.

All substitute candidates must maintain:

• Isolated 4-resistor network topology
• ±1% tolerance specification
• ±200ppm/°C temperature coefficient
• 1206 (3216 Metric) surface mount package
• 8-pin configuration
• Automotive AEC-Q200 qualification
• ROHS3 compliance

Parameter Comparison

Engineering Selection Recommendations

TC164-FR-075K11L (YAGEO) is the primary substitute for new designs and production transitions. This part maintains direct electrical equivalence with identical resistance value, tolerance, power rating, and temperature coefficient. Active product status ensures long-term availability and supply chain continuity. Full compliance with ROHS3 and automotive AEC-Q200 qualification provides equivalent regulatory and quality assurance standing. Package geometry (Concave, Long Side Terminals) matches the original specification exactly.

RAVF164DFT5K10 (Stackpole Electronics Inc) serves as a secondary alternative when enhanced power dissipation capability is beneficial. The 100mW per element rating provides 60% additional thermal headroom compared to the original 62.5mW specification. Nominal resistance of 5.1k Ohm falls within the ±1% tolerance band of the 5.11k Ohm specification, maintaining functional compatibility. Package geometry differs (Convex vs. Concave terminals), requiring verification of PCB layout compatibility before implementation. Active product status and identical manufacturer origin to the original part support supply chain familiarity.

Frequently Asked Questions (FAQ)

Q: Can TC164-FR-075K11L replace RACF164DFT5K11 in existing designs without modification?

A: Yes. TC164-FR-075K11L provides direct electrical and mechanical equivalence. Identical resistance value, tolerance, power rating, temperature coefficient, and package configuration ensure pin-for-pin compatibility without circuit redesign.

Q: What is the resistance tolerance overlap between RACF164DFT5K11 and RAVF164DFT5K10?

A: Both parts carry ±1% tolerance. RACF164DFT5K11 nominal value is 5.11k Ohm (range: 5.059k – 5.161k Ohm). RAVF164DFT5K10 nominal value is 5.1k Ohm (range: 5.049k – 5.151k Ohm). The tolerance bands overlap significantly, supporting functional substitution in applications where the nominal 0.01k Ohm difference is acceptable.

Q: Does the package geometry difference between TC164-FR-075K11L (Concave) and RAVF164DFT5K10 (Convex) affect PCB compatibility?

A: Package geometry differences may affect solder joint formation and PCB layout spacing. Verify that existing PCB footprints accommodate the terminal profile of the substitute part before production implementation. Height specifications differ slightly (TC164-FR: 0.028" max vs. RAVF164: 0.024" max), which may impact clearance in densely populated assemblies.

Q: Are all substitute parts automotive AEC-Q200 qualified?

A: Yes. Both TC164-FR-075K11L and RAVF164DFT5K10 carry automotive AEC-Q200 qualification, matching the original RACF164DFT5K11 specification.

Q: What is the primary advantage of RAVF164DFT5K10 over TC164-FR-075K11L?

A: RAVF164DFT5K10 provides 100mW per element power rating versus 62.5mW in both the original and TC164-FR-075K11L. This 60% increase in thermal capacity may benefit applications with elevated power dissipation requirements or thermal margin requirements.

Q: Can RACF164DFT5K11 be sourced as new original stock?

A: RACF164DFT5K11 is classified as obsolete. Current inventory of 790 pieces is available as new original stock, but long-term availability is not assured. Transition to active alternatives (TC164-FR-075K11L or RAVF164DFT5K10) is recommended for designs with extended production lifecycles.
