RP164PJ683CS Equivalent & Substitute Parts

Part Overview

The RP164PJ683CS is a 68kΩ isolated resistor array manufactured by Samsung Electro-Mechanics, featuring four independent resistor elements in a 1206 (3216 Metric) surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. The part delivers 62.5mW power per element with ±5% tolerance and ±200ppm/°C temperature coefficient across an operating range of -55°C to 155°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ683CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 68kΩ
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Package designation: 1206 (3216 Metric), Convex, Long Side Terminals
• Pin count: 8
• Mounting technology: Surface Mount

Allowable Variation:

• Power per element may exceed the original specification (62.5mW minimum required)
• Product status may differ (active vs. obsolete)
• Packaging format (tape & reel vs. bulk) does not affect electrical compatibility

The RAVF164DJT68K0 manufactured by Stackpole Electronics Inc meets all mandatory parameters and qualifies as a direct electrical and mechanical substitute.

Engineering Selection Recommendations

The RAVF164DJT68K0 is qualified as a direct substitute for the RP164PJ683CS based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters match exactly, including resistance value, tolerance, temperature coefficient, and operating temperature range. The higher power rating per element (100mW vs. 62.5mW) provides additional thermal margin and does not compromise circuit performance.

Mechanical Compatibility: Both components share identical package dimensions, pin configuration, and mounting footprint. The seated height difference (0.60mm vs. 0.61mm) is negligible and within standard PCB assembly tolerances.

Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Product Availability: The RAVF164DJT68K0 maintains active product status with established supply chain availability, addressing the obsolescence risk of the original Samsung component.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT68K0 be used as a direct replacement on existing PCBs designed for RP164PJ683CS?

A: Yes. The RAVF164DJT68K0 is mechanically and electrically compatible. Identical footprint, pin count, and package dimensions ensure direct PCB compatibility without layout modifications.

Q: Does the higher power rating (100mW vs. 62.5mW) of the Stackpole part affect circuit operation?

A: No. Higher power rating indicates greater thermal capacity and does not alter electrical performance. The component will operate within the same voltage and current parameters as the original.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 rating. The Stackpole part includes AEC-Q200 automotive qualification, which is an additional certification not present in the Samsung part. This does not restrict use in non-automotive applications.

Q: What is the significance of the "Isolated" circuit type?

A: Isolated configuration means each of the four resistor elements operates independently with no internal connections between them. This allows flexible circuit design where resistors can be configured for different applications within a single package.

Q: Does packaging format (Tape & Reel vs. bulk) affect electrical performance?

A: No. Packaging format is a logistics and handling consideration only. Electrical and mechanical specifications remain identical regardless of packaging method.

Q: Are the dimensional tolerances between the two parts compatible for automated assembly?

A: Yes. The seated height difference of 0.01mm (0.61mm vs. 0.60mm) is within standard PCB assembly machine tolerances and will not cause placement or soldering issues.
