RP164PJ274CS Equivalent & Substitute Parts

Part Overview

The RP164PJ274CS is a 270k Ohm isolated resistor array manufactured by Samsung Electro-Mechanics. This surface mount component features four independent resistors in a 1206 (3216 Metric) convex package with long side terminals. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

The RP164PJ274CS delivers 62.5mW power per element with ±5% tolerance and ±200ppm/°C temperature coefficient across an operating range of -55°C to 155°C. As an isolated circuit type resistor network, each resistor element functions independently within the 8-pin package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP164PJ274CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 270k Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Mounting type: Surface Mount
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Allowable Variation:

• Power per element: Substitute parts may exceed the original 62.5mW specification, provided the higher power rating does not create thermal or design constraints in the application circuit.

The RAVF164DJT270K from Stackpole Electronics Inc satisfies all mandatory parameters and provides increased power dissipation capability (100mW per element), making it a direct functional substitute for the obsolete RP164PJ274CS.

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT270K is the qualified substitute for the obsolete RP164PJ274CS based on the following engineering criteria:

Electrical Equivalence: Both components provide identical resistance value (270k Ohm), tolerance (±5%), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 155°C). The isolated circuit topology with four independent resistor elements is preserved.

Mechanical Compatibility: Package dimensions, pin configuration, and mounting type are identical. Both components use the 1206 (3216 Metric) convex package with long side terminals and 8-pin configuration, ensuring direct PCB footprint compatibility without layout modification.

Regulatory Compliance: The RAVF164DJT270K maintains ROHS3 compliance and MSL 1 (Unlimited) rating, matching the environmental and handling requirements of the original part. Both components carry EAR99 ECCN classification.

Product Status Advantage: The RAVF164DJT270K is classified as Active, ensuring long-term availability and supply chain continuity. The original RP164PJ274CS is obsolete, making the Stackpole substitute the appropriate choice for new designs and ongoing production support.

Power Dissipation: The RAVF164DJT270K provides 100mW per element compared to the original 62.5mW specification. This increased power rating offers design margin and thermal headroom without introducing compatibility issues.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT270K be used as a direct replacement for the RP164PJ274CS in existing designs?

A: Yes. The RAVF164DJT270K is electrically and mechanically equivalent to the RP164PJ274CS. Identical resistance value, tolerance, temperature coefficient, operating range, package dimensions, and pin configuration enable direct substitution without circuit modification or PCB redesign.

Q: What is the significance of the higher power rating (100mW vs. 62.5mW) in the RAVF164DJT270K?

A: The increased power per element rating in the RAVF164DJT270K provides additional thermal capacity. This does not create incompatibility; rather, it offers design margin. Applications operating within the original 62.5mW specification will function identically with the higher-rated substitute.

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 height of 0.024" (0.61mm for RP164PJ274CS, 0.60mm for RAVF164DJT270K). These dimensions are functionally equivalent for PCB assembly and clearance calculations.

Q: Does the RAVF164DJT270K meet the same environmental and regulatory standards?

A: Yes. The RAVF164DJT270K is ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part. Both components carry EAR99 ECCN classification and REACH Unaffected status.

Q: Why is the RP164PJ274CS listed as obsolete?

A: The RP164PJ274CS is classified as obsolete by Samsung Electro-Mechanics, indicating discontinued production and limited future availability. The RAVF164DJT270K from Stackpole Electronics Inc is classified as Active, ensuring reliable long-term supply for new designs and production continuity.

Q: Is the isolated circuit topology preserved in the substitute part?

A: Yes. Both the RP164PJ274CS and RAVF164DJT270K are isolated 4-resistor networks with 8 pins. Each resistor element functions independently, maintaining the original circuit topology and electrical isolation characteristics.

Q: What packaging format is available for the RAVF164DJT270K?

A: The RAVF164DJT270K is supplied in Tape & Reel (TR) format, standard for surface mount resistor array components in production environments.
