Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ6R8CS is determined by the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 6.8 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Pin count: 8
• Operating temperature range: -55°C ~ 155°C minimum
• Surface mount compatibility

Allowable Variation Parameters:

• Power per element: May exceed 62.5mW (higher power rating is acceptable)
• Temperature coefficient: May be tighter than ±300ppm/°C (lower drift is acceptable)
• Product status: Active status preferred for long-term availability

The RAVF164DJT6R80 from Stackpole Electronics Inc meets all mandatory criteria while offering enhanced specifications in power handling and temperature stability.

Engineering Selection Recommendations

The RAVF164DJT6R80 is a direct functional equivalent to the RP164PJ6R8CS with superior long-term availability due to its active product status. Selection of the Stackpole substitute is supported by the following engineering factors:

Compliance & Certification: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across applications. The Stackpole part carries AEC-Q200 automotive qualification, extending its applicability to automotive-grade applications where the Samsung part may not be specified.

Performance Enhancement: The RAVF164DJT6R80 provides 100mW power per element versus 62.5mW in the original part, offering 60% additional power dissipation capacity. The temperature coefficient of ±200ppm/°C represents a 33% improvement in thermal stability compared to the ±300ppm/°C specification of the RP164PJ6R8CS.

Physical & Electrical Compatibility: Identical package dimensions, pin configuration, and mounting characteristics ensure direct PCB-level substitution without layout modification. The negligible 0.01mm difference in seated height falls within standard manufacturing tolerances and does not affect assembly or performance.

Procurement Continuity: With 908 units in current inventory and active product status, the RAVF164DJT6R80 provides assured long-term supply compared to the obsolete RP164PJ6R8CS.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT6R80 be used as a direct replacement for the RP164PJ6R8CS on existing PCBs?

A: Yes. Both components share identical package geometry (1206 / 3216 Metric), pin count (8), and terminal configuration (Convex, Long Side). No PCB layout modifications are required for substitution.

Q: What is the significance of the higher power rating (100mW vs 62.5mW) in the Stackpole part?

A: The increased power per element rating provides additional thermal margin and allows operation at higher current levels without exceeding component limits. This represents an enhancement that does not compromise compatibility with designs specified for the lower 62.5mW rating.

Q: Does the improved temperature coefficient (±200ppm/°C) affect circuit performance?

A: The tighter temperature coefficient of the RAVF164DJT6R80 reduces resistance drift across the -55°C to 155°C operating range, resulting in improved circuit stability and reduced temperature-induced tolerance stack-up. This is a performance improvement for applications sensitive to resistance variation.

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

A: Both components are ROHS3 compliant and REACH unaffected. The RAVF164DJT6R80 carries additional AEC-Q200 automotive qualification, making it suitable for automotive applications where the Samsung part may lack specific qualification.

Q: What is the physical height difference between these components?

A: The seated height difference is 0.01mm (0.61mm vs 0.60mm), which is negligible and falls within standard PCB assembly tolerances. This difference does not affect component placement, soldering, or clearance considerations.

Q: Is the RAVF164DJT6R80 available in the same packaging format?

A: Yes. Both components are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes. The Stackpole part is currently in active production with 908 units in stock.

Q: Can I use the RAVF164DJT6R80 in applications originally designed for the RP164PJ6R8CS?

A: Yes. The electrical specifications (6.8 Ohm ±5%, 4-element isolated configuration) and operating parameters (-55°C to 155°C) are identical. The enhanced power rating and improved temperature coefficient make the Stackpole part suitable for all applications specified for the Samsung original.
