RoHS3 compliance

Secondary Consideration:

Power per element rating: Substitutes with equal or higher power ratings are acceptable

The substitute parts are grouped into two categories based on terminal configuration and power rating:

Group 1 - Direct Electrical Equivalents (Concave Terminal Configuration): TC164-FR-07100RL (YAGEO) and CAT16-1000F4LF (Bourns Inc.) maintain identical electrical specifications and concave terminal geometry matching the original RACF164DFT100R.

Group 2 - Enhanced Performance Alternative (Convex Terminal Configuration): RAVF164DFT100R (Stackpole Electronics Inc.) provides increased power per element (100mW vs. 62.5mW) with convex terminal configuration, suitable for applications requiring higher power dissipation capability.

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications: TC164-FR-07100RL (YAGEO) is the primary recommended substitute. This part maintains full electrical and mechanical compatibility with the RACF164DFT100R, including identical power per element rating, concave terminal configuration, and operating temperature range. YAGEO TC164 series holds active product status with substantial inventory availability (4400 Pcs), ensuring supply chain continuity.

For Stackpole Electronics Inc Ecosystem: RAVF164DFT100R (Stackpole Electronics Inc.) provides a manufacturer-direct alternative within the same product family. This part offers enhanced power per element (100mW), maintaining all other critical specifications. The convex terminal configuration represents a minor mechanical variation that may require PCB layout assessment. This option is suitable for applications where increased power dissipation capability provides design margin.

For High-Volume Production: CAT16-1000F4LF (Bourns Inc.) offers the largest inventory availability (71599 Pcs) and maintains electrical equivalence with the original part. Note that the operating temperature range is limited to -55°C to 125°C, which is acceptable for applications not requiring the full 155°C upper limit of the RACF164DFT100R. This part does not carry AEC-Q200 qualification and is not recommended for automotive applications requiring this certification.

Frequently Asked Questions (FAQ)

Q: Can RAVF164DFT100R be used as a direct replacement for RACF164DFT100R?

A: RAVF164DFT100R is electrically compatible with identical resistance, tolerance, temperature coefficient, and operating range. The primary difference is the terminal configuration (convex vs. concave) and increased power per element (100mW vs. 62.5mW). PCB layout compatibility must be assessed due to terminal geometry differences.

Q: What is the significance of the terminal configuration (concave vs. convex)?

A: Terminal configuration affects solder joint geometry and PCB pad design. Concave terminals (RACF164DFT100R, TC164-FR-07100RL, CAT16-1000F4LF) and convex terminals (RAVF164DFT100R) require different pad layouts. Existing PCB designs optimized for concave terminals should use concave-configured substitutes to avoid rework.

Q: Is CAT16-1000F4LF suitable for automotive applications?

A: CAT16-1000F4LF meets RoHS3 compliance and operates within the required temperature range for most applications. However, this part does not carry AEC-Q200 automotive qualification. Applications requiring AEC-Q200 certification must use TC164-FR-07100RL or RAVF164DFT100R.

Q: What is the impact of the 62.5mW vs. 100mW power rating difference?

A: Power per element rating indicates maximum continuous power dissipation capability per resistor. The RACF164DFT100R and its direct equivalents (TC164-FR-07100RL, CAT16-1000F4LF) are rated at 62.5mW per element. RAVF164DFT100R provides 100mW per element, offering additional thermal margin for high-power applications. Substituting a lower-power part into a high-power application is not acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RACF164DFT100R, RAVF164DFT100R, TC164-FR-07100RL, and CAT16-1000F4LF are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the operating temperature range limitation for CAT16-1000F4LF?

A: CAT16-1000F4LF operates from -55°C to 125°C, compared to -55°C to 155°C for the original RACF164DFT100R. This part is not suitable for applications requiring operation above 125°C.
