Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ5R6CS is determined by the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 5.6 Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Number of pins: 8
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Operating temperature range: -55°C ~ 155°C minimum
• Mounting type: Surface Mount

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
• Compliance certifications: ROHS3 compliance required

The RAVF164DJT5R60 from Stackpole Electronics Inc meets all mandatory criteria and exceeds performance specifications in power rating and temperature stability, qualifying it as a direct substitute.

Engineering Selection Recommendations

Primary Substitute: RAVF164DJT5R60

The RAVF164DJT5R60 is the qualified substitute for the obsolete RP164PJ5R6CS. Selection rationale:

1. Functional Equivalence: All mandatory electrical and mechanical parameters match exactly. The 1206 package footprint, pin configuration, and isolated 4-resistor topology ensure direct PCB compatibility without layout modifications.

2. Enhanced Performance: The substitute provides superior specifications in two areas:

   • Power rating increased from 62.5mW to 100mW per element, providing additional thermal margin
   • Temperature coefficient improved from ±300ppm/°C to ±200ppm/°C, delivering better long-term stability

3. Product Status and Availability: The RAVF164DJT5R60 maintains active production status, ensuring long-term procurement availability and supply chain continuity compared to the obsolete RP164PJ5R6CS.

4. Compliance and Certification: Both components maintain ROHS3 compliance and MSL 1 rating. The Stackpole substitute carries AEC-Q200 automotive qualification, indicating rigorous reliability testing and suitability for demanding applications.

5. Packaging: Available in Tape & Reel format, supporting automated assembly processes.

No design modifications, simulation updates, or functional re-qualification are required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT5R60 be used as a direct replacement for the RP164PJ5R6CS without PCB modifications?

A: Yes. Both components share identical package dimensions (1206 / 3216 Metric), footprint, pin count (8), and terminal configuration (Convex, Long Side Terminals). No PCB layout changes are necessary.

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

A: The increased power rating indicates the substitute can dissipate more thermal energy per resistor element. This provides additional design margin and thermal headroom in applications operating near the original component's power limits. The substitute will not cause circuit malfunction in designs rated for the original 62.5mW specification.

Q: Does the improved temperature coefficient (±200ppm/°C vs. ±300ppm/°C) affect circuit performance?

A: The tighter temperature coefficient in the substitute indicates lower resistance drift across the -55°C to 155°C operating range. This improves long-term stability and accuracy in precision applications. Circuits designed for the original ±300ppm/°C specification will experience equal or better performance with the substitute.

Q: Why is the RP164PJ5R6CS listed as obsolete?

A: Obsolete status indicates Samsung Electro-Mechanics has discontinued production and support for this component. The RAVF164DJT5R60 from Stackpole Electronics Inc provides equivalent functionality with active production status, ensuring availability for new designs and ongoing production support.

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

A: Both components are ROHS3 compliant with MSL 1 rating. The RAVF164DJT5R60 carries additional AEC-Q200 automotive qualification, indicating it has undergone enhanced reliability testing. This certification is beneficial for automotive and high-reliability applications but does not restrict use in other markets.

Q: What is the difference between the packaging formats (-) for the original and Tape & Reel (TR) for the substitute?

A: The original part's packaging format was not specified in available documentation. The substitute's Tape & Reel format is the standard for automated surface mount assembly, supporting high-volume production and pick-and-place equipment. This format is compatible with standard manufacturing processes.

Q: Can both parts be used interchangeably in existing inventory?

A: Yes, from an electrical and mechanical standpoint. However, inventory management should account for the different manufacturers and part numbers. The substitute's active production status makes it preferable for new stock procurement.
