Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

YC164-JR-0768RL from YAGEO is the primary direct equivalent. This part maintains identical electrical specifications (68 Ohm ±5%, 62.5mW per element, ±200ppm/°C) and operating temperature range (-55°C to 155°C). The part is active in production with AEC-Q200 automotive qualification and ROHS3 compliance. Inventory availability is substantial (35,400 pcs). This part is suitable for applications requiring no performance enhancement.

742X083680JP from CTS Resistor Products is a secondary direct equivalent with marginally higher power per element (63mW vs 62.5mW) and reduced maximum operating temperature (125°C vs 155°C). This part is active with AEC-Q200 qualification and ROHS3 compliance. Selection of this part requires verification that the application does not require operation above 125°C.

For Enhanced Performance (Upgrade Specification):

RAVF164DFT68R0 from Stackpole Electronics Inc provides improved tolerance (±1% vs ±5%) and higher power per element (100mW vs 62.5mW) while maintaining the full operating temperature range (-55°C to 155°C). This part is active with AEC-Q200 automotive qualification and ROHS3 compliance. Selection of this part is appropriate for applications requiring tighter resistance tolerance or higher thermal margin.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). All three substitutes carry AEC-Q200 automotive qualification, providing enhanced reliability assurance for automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can YC164-JR-0768RL replace RP164PJ680CS in all applications?

A: Yes, YC164-JR-0768RL is a direct electrical and mechanical equivalent. Both parts specify 68 Ohm ±5%, 62.5mW per element, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. The 1206 package, pin count (8), and isolated circuit topology are identical. No design changes are required.

Q: What is the difference between the CTS 742X083680JP and YAGEO YC164-JR-0768RL?

A: Both are direct equivalents with identical resistance, tolerance, and temperature coefficient. The CTS part has marginally higher power per element (63mW vs 62.5mW) and a reduced maximum operating temperature of 125°C instead of 155°C. Selection depends on application temperature requirements. If the application operates above 125°C, the YAGEO part is required.

Q: When should RAVF164DFT68R0 be selected instead of direct equivalents?

A: The Stackpole RAVF164DFT68R0 should be selected when the application requires tighter resistance tolerance (±1% vs ±5%) or higher power dissipation capability (100mW vs 62.5mW per element). This part is an upgrade specification suitable for precision circuits or thermally demanding applications.

Q: Are all substitute parts automotive qualified?

A: Yes. All three substitute parts (YC164-JR-0768RL, 742X083680JP, and RAVF164DFT68R0) carry AEC-Q200 automotive qualification. The original RP164PJ680CS does not specify automotive qualification.

Q: What is the impact of the 0.10mm height difference between parts?

A: The RP164PJ680CS and RAVF164DFT68R0 have maximum seated height of 0.60mm, while YC164-JR-0768RL and 742X083680JP have 0.70mm. This 0.10mm difference is within typical PCB assembly tolerances and does not affect electrical performance. Verification is required only if the application has strict height constraints (e.g., confined spaces, stacked assemblies).

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts use identical 1206 (3216 Metric) package with convex, long side terminals and 8-pin configuration. PCB footprints, solder pad layouts, and assembly processes are compatible without modification.

Q: What is the significance of the operating temperature range difference?

A: The CTS 742X083680JP specifies -55°C to 125°C, while the original part and other substitutes specify -55°C to 155°C. If the application requires operation above 125°C, the CTS part is not suitable. For applications with maximum operating temperature at or below 125°C, all parts are acceptable.

Q: Are there any moisture sensitivity concerns?

A: No. All parts specify Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity. Standard handling and storage procedures apply without special precautions.
