Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RP164PJ392CS are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 3.9k Ohm (exact match required)
• Circuit type: Isolated configuration (4 independent resistor elements)
• Number of resistors: 4 elements
• Number of pins: 8-pin configuration
• Package type: 1206 (3216 Metric) surface mount with convex, long side terminals
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Temperature coefficient: ±200ppm/°C (maximum drift specification)
• Mounting type: Surface mount (PCB compatibility)

Allowable Parameter Variations:

• Tolerance: May be equal or tighter (±5% or better)
• Power per element: May be equal or higher (62.5mW or greater)
• Product status: Active preferred over obsolete
• Compliance certifications: ROHS3, REACH status maintained

The two substitute parts listed below meet all critical matching parameters and are therefore electrically and mechanically interchangeable with the RP164PJ392CS in standard applications.

Engineering Selection Recommendations

YC164-JR-073K9L (YAGEO) - Direct Equivalent

The YC164-JR-073K9L is a direct functional equivalent to the RP164PJ392CS. This part maintains identical electrical specifications including 3.9k Ohm resistance, ±5% tolerance, 62.5mW power per element, and ±200ppm/°C temperature coefficient. The component is currently in Active product status with 11,836 pieces in stock, ensuring reliable supply availability. Physical dimensions and package configuration are identical. ROHS3 compliance and REACH Unaffected status are maintained. The YC164-JR-073K9L is qualified for Automotive AEC-Q200 applications, providing additional qualification assurance. Height seated maximum is 0.028" (0.70mm), which is 0.004" higher than the original part but remains within standard PCB assembly tolerances for 1206 package components.

RAVF164DFT3K90 (Stackpole Electronics Inc) - Enhanced Specification Upgrade

The RAVF164DFT3K90 is an upgraded substitute offering improved electrical performance characteristics. This part maintains the same 3.9k Ohm resistance value, circuit topology, and package configuration as the RP164PJ392CS. Key enhancements include tighter tolerance specification (±1% versus ±5%) and increased power per element rating (100mW versus 62.5mW). Temperature coefficient and operating temperature range remain identical at ±200ppm/°C and -55°C ~ 155°C respectively. The component is in Active product status with 871 pieces in stock. ROHS3 compliance and REACH Unaffected status are maintained. Automotive AEC-Q200 qualification is provided. Height seated maximum is 0.024" (0.60mm), matching the original part specification exactly. The enhanced power rating provides additional thermal margin in applications approaching the original 62.5mW per element limit.

Frequently Asked Questions (FAQ)
