RP164PJ161CS Equivalent & Substitute Parts

Part Overview

The RP164PJ161CS is a 160 Ohm isolated resistor array manufactured by Samsung Electro-Mechanics, featuring four independent resistor elements in a 1206 (3216 Metric) surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The part delivers 62.5mW power per element with ±5% tolerance and ±200ppm/°C temperature coefficient across an operating range of -55°C to 155°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP164PJ161CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 160 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Pin count: 8
• Mounting type: Surface Mount

Allowable Variation:

• Power per element may exceed the original specification (62.5mW minimum required)
• Packaging format (Tape & Reel vs. bulk) does not affect electrical compatibility

The RAVF164DJT160R from Stackpole Electronics Inc meets all mandatory matching parameters and provides increased power dissipation capability (100mW per element), making it a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT160R is a direct electrical and mechanical substitute for the RP164PJ161CS. Both components share identical resistance, tolerance, temperature coefficient, operating temperature range, package dimensions, and pin configuration. The Stackpole part carries active product status, ensuring continued availability and supply chain reliability compared to the obsolete Samsung component.

The RAVF164DJT160R provides enhanced power dissipation (100mW per element versus 62.5mW), which represents a performance improvement and does not introduce compatibility constraints. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

The Stackpole component includes AEC-Q200 automotive qualification, providing additional certification coverage for applications requiring automotive-grade reliability standards.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT160R replace the RP164PJ161CS in existing designs?

A: Yes. The RAVF164DJT160R is electrically and mechanically equivalent. Identical resistance, tolerance, temperature coefficient, operating temperature range, and package configuration ensure direct substitution without circuit redesign.

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

A: The increased power per element rating indicates greater thermal capability. This does not affect compatibility; the substitute can safely operate in applications designed for the original 62.5mW specification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components use the 1206 (3216 Metric) package with convex, long side terminals. Dimensions are 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 differences are negligible for PCB assembly and placement.

Q: Does the packaging format (Tape & Reel vs. bulk) affect electrical performance?

A: No. Packaging format is a supply and handling consideration only. Electrical and mechanical properties remain identical regardless of packaging method.

Q: What compliance certifications apply to both parts?

A: Both the RP164PJ161CS and RAVF164DJT160R are ROHS3 compliant and REACH unaffected. The Stackpole part additionally carries AEC-Q200 automotive qualification.

Q: Why is the Samsung part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Stackpole RAVF164DJT160R maintains active product status, providing long-term procurement security.
