Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ514CS is determined by the following critical parameters:

Mandatory Matching Parameters:

Resistance value: 510k Ohm
Tolerance: ±5%
Number of resistors: 4
Circuit type: Isolated
Temperature coefficient: ±200ppm/°C
Operating temperature range: -55°C ~ 155°C
Package type: 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 62.5mW specification, provided the higher power rating does not introduce thermal or reliability concerns in the application circuit.

The RAVF164DJT510K from Stackpole Electronics Inc meets all mandatory matching parameters and provides increased power dissipation capability (100mW per element), making it a direct functional substitute.

Engineering Selection Recommendations

The RAVF164DJT510K is the qualified substitute for the obsolete RP164PJ514CS based on the following factors:

Electrical Compatibility: Both components share identical resistance values, tolerance specifications, temperature coefficients, and operating temperature ranges. The isolated circuit topology and pin configuration are identical, ensuring direct functional replacement without circuit redesign.

Mechanical Compatibility: Package dimensions, pin count, and mounting type are identical. Both components utilize the 1206 (3216 Metric) convex package with long side terminals, confirming PCB footprint compatibility.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.

Product Status Advantage: The RAVF164DJT510K is classified as active, ensuring long-term availability and supply chain continuity compared to the obsolete RP164PJ514CS.

Power Dissipation: The Stackpole substitute provides 100mW per element versus 62.5mW in the original Samsung part. This increased power rating enhances thermal margin and reliability in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT510K be used as a direct replacement for the RP164PJ514CS without PCB modifications?

A: Yes. Both components share identical package dimensions, pin configuration, and footprint specifications. No PCB layout changes are required for substitution.

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

A: The increased power dissipation capability provides additional thermal headroom. The substitute can safely handle higher power levels without exceeding temperature limits, improving reliability margins in the application circuit.

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

A: Both components are ROHS3 compliant and REACH unaffected. The Stackpole part includes AEC-Q200 automotive qualification, which is not specified for the Samsung original. This additional qualification does not restrict use in non-automotive applications.

Q: Why is the RP164PJ514CS classified as obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life decisions. The RAVF164DJT510K, classified as active, provides equivalent functionality with assured long-term availability.

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

A: Yes. Both components measure 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum seated heights of 0.024" (0.61mm and 0.60mm respectively). These minimal height differences are within standard PCB assembly tolerances.

Q: What packaging formats are available for the substitute part?

A: The RAVF164DJT510K is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
