RP164PJ1R8CS Equivalent & Substitute Parts Reference

Part Overview

The RP164PJ1R8CS is a 1.8 Ohm isolated 4-resistor network array manufactured by Samsung Electro-Mechanics in a 1206 (3216 Metric) surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. 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. Due to its obsolete status, equivalent substitutes with matching electrical and mechanical specifications are required for new procurement and design revisions.

Engineering Selection Recommendations

The RAVF164DJT1R80 manufactured by Stackpole Electronics Inc is a qualified substitute for the obsolete RP164PJ1R8CS. Selection is based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters align precisely: 1.8 Ohm resistance, ±5% tolerance, isolated 4-resistor configuration, and 8-pin arrangement. The substitute meets or exceeds the original part's performance specifications with 100mW power per element (versus 62.5mW) and superior temperature coefficient of ±200ppm/°C (versus ±300ppm/°C).

Mechanical Compatibility: The RAVF164DJT1R80 maintains identical package specifications: 1206 (3216 Metric) with convex, long side terminals, matching physical dimensions of 3.20mm x 1.60mm and seated height of 0.60mm. Surface mount configuration ensures direct PCB assembly compatibility without design modification.

Regulatory and Compliance Status: Both parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 classification. The substitute carries AEC-Q200 automotive qualification, indicating enhanced reliability testing and process controls. The substitute's active production status ensures long-term availability compared to the obsolete original part.

Inventory and Availability: The RAVF164DJT1R80 is currently in active production with 854 pieces available in new original condition, providing immediate procurement capability for design transitions and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT1R80 be used as a direct replacement for the RP164PJ1R8CS without PCB modifications?

A: Yes. The RAVF164DJT1R80 is mechanically and electrically compatible with the RP164PJ1R8CS. Identical package dimensions, pinout configuration, and footprint specifications eliminate the need for PCB layout changes. Both components use the 1206 (3216 Metric) package with convex, long side terminals and 8-pin isolated configuration.

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

A: The primary differences are manufacturer origin and performance enhancements. The RAVF164DJT1R80 provides higher power dissipation per element (100mW versus 62.5mW) and improved temperature stability (±200ppm/°C versus ±300ppm/°C). The substitute includes AEC-Q200 automotive qualification, while the original part carries no specific qualification designation. The substitute is in active production; the original is obsolete.

Q: Are there any thermal or electrical performance concerns when substituting the RAVF164DJT1R80 for the RP164PJ1R8CS?

A: No. The substitute's higher power rating and superior temperature coefficient represent performance improvements. The 100mW per element rating provides additional thermal margin compared to the 62.5mW requirement of the original part. The ±200ppm/°C temperature coefficient ensures better resistance stability across the -55°C to 155°C operating range.

Q: Does the RAVF164DJT1R80 meet the same compliance requirements as the RP164PJ1R8CS?

A: Yes. Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 classification. The substitute additionally qualifies under AEC-Q200 automotive standards, indicating compliance with enhanced reliability and quality requirements applicable to automotive applications.

Q: What is the packaging difference between these parts?

A: The RP164PJ1R8CS is supplied in standard packaging, while the RAVF164DJT1R80 is supplied in Tape & Reel (TR) format. Both use identical component specifications and package dimensions. Tape & Reel packaging is standard for high-volume surface mount assembly operations and does not affect component performance or compatibility.

Q: Is the RAVF164DJT1R80 suitable for applications requiring automotive-grade components?

A: Yes. The RAVF164DJT1R80 carries AEC-Q200 qualification, meeting automotive industry standards for reliability and quality. The original RP164PJ1R8CS does not specify automotive qualification. For automotive applications, the substitute provides enhanced qualification credentials.

Q: What is the current availability status of these parts?

A: The RP164PJ1R8CS is obsolete with 942 pieces in existing inventory. The RAVF164DJT1R80 is in active production with 854 pieces currently available. For new designs and ongoing production, the RAVF164DJT1R80 is the recommended selection due to active manufacturing status and long-term availability assurance.
