RP164PJ1R5CS Equivalent & Substitute Parts Reference

Part Overview

The RP164PJ1R5CS is a 1.5 Ohm isolated resistor array manufactured by Samsung Electro-Mechanics, featuring four resistor elements in a 1206 (3216 Metric) surface mount package with convex, long side terminals. This component is classified as obsolete product status, necessitating identification of active equivalent alternatives to maintain supply chain continuity for new designs and production requirements.

The part delivers 62.5mW power per element with ±5% tolerance and ±300ppm/°C temperature coefficient across an operating range of -55°C to 155°C. The isolated circuit configuration provides independent resistor elements suitable for applications requiring discrete resistor networks in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ1R5CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.5 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Operating temperature range: -55°C to 155°C minimum
• Mounting type: Surface Mount

Allowable Variation Parameters:

• Power per element: Substitute must equal or exceed 62.5mW
• Temperature coefficient: Substitute may differ from ±300ppm/°C
• Product status: Active alternatives are preferred for obsolete parts

The RAVF164DJT1R50 from Stackpole Electronics Inc qualifies as a direct substitute based on identical resistance, tolerance, element count, circuit type, package configuration, pin count, and operating temperature range. The substitute provides enhanced power rating (100mW vs 62.5mW per element) and improved temperature stability (±200ppm/°C vs ±300ppm/°C), with active product status ensuring ongoing availability.

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT1R50 from Stackpole Electronics Inc is a direct functional equivalent to the obsolete RP164PJ1R5CS. Both components maintain identical electrical specifications for resistance value, tolerance, and circuit configuration, with identical mechanical compatibility in 1206 (3216 Metric) surface mount package format.

The substitute part provides performance advantages in two areas: increased power dissipation capability (100mW vs 62.5mW per element) and improved temperature stability (±200ppm/°C vs ±300ppm/°C). These enhancements do not introduce incompatibility; they represent superior performance margins for the same application space.

Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory qualification status. The RAVF164DJT1R50 carries active product status with automotive AEC-Q200 qualification, providing enhanced supply chain reliability compared to the obsolete Samsung part.

Pinout and footprint compatibility is confirmed through identical package specification, pin count (8), and terminal configuration (convex, long side terminals). Direct PCB layout substitution is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT1R50 be used as a direct replacement for RP164PJ1R5CS without PCB layout changes?

A: Yes. Both components share identical package type (1206 / 3216 Metric), pin count (8), terminal configuration (convex, long side terminals), and footprint dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm). No PCB layout modification is required.

Q: What are the electrical differences between these two parts?

A: The primary electrical differences are power rating and temperature coefficient. The RAVF164DJT1R50 provides 100mW per element versus 62.5mW for the RP164PJ1R5CS, and maintains ±200ppm/°C temperature coefficient versus ±300ppm/°C. Resistance value (1.5 Ohm), tolerance (±5%), and circuit configuration (isolated, 4 elements) are identical.

Q: Is the higher power rating of the substitute part a concern for circuit compatibility?

A: No. Higher power rating capability does not create incompatibility. The substitute part will operate within the same power dissipation envelope as the original part. The increased rating provides additional thermal margin and design flexibility.

Q: What is the significance of the improved temperature coefficient in the substitute part?

A: The RAVF164DJT1R50 exhibits tighter temperature stability (±200ppm/°C vs ±300ppm/°C), meaning resistance value variation across the -55°C to 155°C operating range is more predictable and smaller in magnitude. This represents improved performance, not a compatibility issue.

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

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The RAVF164DJT1R50 carries additional automotive AEC-Q200 qualification, indicating enhanced reliability testing and supply chain qualification for automotive applications.

Q: What is the packaging difference between these parts?

A: The RP164PJ1R5CS is supplied in standard packaging format. The RAVF164DJT1R50 is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments. Both formats contain identical components; packaging format does not affect electrical or mechanical performance.

Q: Can these parts be used interchangeably in new designs?

A: Yes. The RAVF164DJT1R50 is recommended for new designs due to active product status, ensuring long-term availability and supply chain continuity. The RP164PJ1R5CS is obsolete and should not be specified for new development.
