Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ122CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.2k Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Mounting type: Surface Mount

Allowable Variation:

• Power per element: Substitute parts may exceed the original specification (minimum 62.5mW required)
• Packaging format: Tape & Reel acceptable as alternative to standard packaging
• Product status: Active status preferred for long-term availability

The RAVF164DJT1K20 from Stackpole Electronics Inc meets all mandatory parameters and qualifies as a direct substitute. This part maintains identical electrical specifications while offering increased power dissipation capability (100mW per element versus 62.5mW) and active product status with automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT1K20 is the qualified substitute for the obsolete RP164PJ122CS based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical resistance (1.2k Ohm), tolerance (±5%), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute's increased power dissipation (100mW versus 62.5mW per element) provides enhanced thermal margin without compromising circuit performance.

Physical Compatibility: Identical package dimensions (1206 / 3216 Metric), pin count (8), and terminal configuration (convex, long side) ensure direct PCB footprint compatibility and assembly process alignment.

Compliance & Certification: Both parts are ROHS3 compliant and MSL 1 rated. The RAVF164DJT1K20 carries AEC-Q200 automotive qualification, indicating enhanced reliability screening and process controls suitable for demanding applications.

Availability & Status: The RAVF164DJT1K20 maintains active product status with established supply chain presence, addressing the obsolescence risk of the original Samsung part.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT1K20 be used as a direct replacement for RP164PJ122CS in existing designs?

A: Yes. The RAVF164DJT1K20 is electrically and mechanically compatible. Identical resistance, tolerance, temperature coefficient, operating range, package dimensions, and pin configuration enable direct substitution without circuit redesign or PCB modification.

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

A: The increased power dissipation capability of the RAVF164DJT1K20 provides additional thermal headroom. This does not alter circuit behavior but allows operation at higher current levels without thermal stress. For applications operating within the original 62.5mW specification, this represents a design margin improvement.

Q: Are there differences in temperature stability between the two parts?

A: No. Both parts specify ±200ppm/°C temperature coefficient and operate across the identical -55°C ~ 155°C range. Temperature-dependent resistance drift characteristics are equivalent.

Q: Does the automotive qualification (AEC-Q200) of the substitute part affect its use in non-automotive applications?

A: No. AEC-Q200 qualification indicates enhanced reliability screening and manufacturing controls. This certification is a superset of standard industrial requirements and does not restrict use in non-automotive designs. It represents an improvement in component quality assurance.

Q: What is the difference between the packaging formats (standard vs. Tape & Reel)?

A: Tape & Reel (TR) packaging is the standard format for automated assembly processes. Both formats contain identical components; the difference is in presentation and handling method. Tape & Reel is suitable for high-volume production environments and does not affect component performance or reliability.

Q: Are the physical dimensions truly identical between the two parts?

A: Dimensions are functionally equivalent. Both measure 0.126" L x 0.063" W (3.20mm x 1.60mm). Maximum seated height differs by 0.01mm (0.61mm vs. 0.60mm), which is within standard PCB assembly tolerance and does not affect placement or functionality.

Q: Can the RP164PJ122CS be sourced as a new original component?

A: The RP164PJ122CS is classified as obsolete. While 751 pieces are reported in current inventory, long-term availability cannot be assured. The RAVF164DJT1K20 is the recommended alternative for new designs and ongoing production to ensure supply chain continuity.
