Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ3R3CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 3.3 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Number of pins: 8
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Operating temperature range: -55°C ~ 155°C
• 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 status preferred for long-term availability
• Packaging format: May differ (Tape & Reel acceptable for procurement)

The RAVF164DJT3R30 from Stackpole Electronics Inc satisfies all mandatory criteria and exceeds power rating requirements (100mW vs. 62.5mW), making it a direct functional equivalent.

Engineering Selection Recommendations

The RAVF164DJT3R30 is a direct functional substitute for the obsolete RP164PJ3R3CS. Selection rationale is based on the following engineering factors:

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with current environmental standards. The RAVF164DJT3R30 carries AEC-Q200 automotive qualification, providing additional quality assurance for applications requiring automotive-grade reliability.

Product Lifecycle Status: The RP164PJ3R3CS is classified as obsolete, creating supply chain risk. The RAVF164DJT3R30 maintains active production status, ensuring long-term availability and procurement stability.

Electrical Performance: The RAVF164DJT3R30 exceeds the power rating specification (100mW vs. 62.5mW per element) and demonstrates improved temperature stability (±200ppm/°C vs. ±300ppm/°C). These enhancements provide design margin without introducing incompatibility.

Physical & Mechanical Compatibility: Identical package dimensions, pin count, and mounting configuration ensure direct PCB-level compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT3R30 be used as a direct replacement for the RP164PJ3R3CS without PCB modification?

A: Yes. Both parts share identical package geometry (1206 / 3216 Metric), pin count (8), and terminal configuration (convex, long side). No PCB layout changes are required.

Q: What is the significance of the higher power rating (100mW vs. 62.5mW) on the RAVF164DJT3R30?

A: The higher power rating provides additional thermal margin and design headroom. Applications designed for 62.5mW operation will function within the RAVF164DJT3R30 specification envelope without thermal stress.

Q: How does the improved temperature coefficient (±200ppm/°C) affect circuit performance?

A: The lower temperature coefficient indicates reduced resistance drift across the -55°C to 155°C operating range. This improves circuit stability and measurement accuracy in temperature-sensitive applications. The change is compatible with designs specified for ±300ppm/°C.

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

A: Both parts are ROHS3 compliant and REACH unaffected. The RAVF164DJT3R30 additionally carries AEC-Q200 automotive qualification, which is not a restriction but an enhancement for applications requiring automotive-grade reliability.

Q: What is the difference between the packaging formats listed (bulk vs. Tape & Reel)?

A: The RP164PJ3R3CS is listed with standard packaging, while the RAVF164DJT3R30 is supplied in Tape & Reel (TR) format. Tape & Reel is the industry standard for automated assembly and does not affect component functionality or performance.

Q: Is the RAVF164DJT3R30 suitable for high-reliability applications?

A: Yes. The part maintains MSL 1 (Unlimited) moisture sensitivity rating and carries AEC-Q200 qualification, making it suitable for automotive and high-reliability applications.

Q: Can multiple RP164PJ3R3CS units be replaced with RAVF164DJT3R30 units in existing inventory?

A: Yes. The electrical and mechanical specifications are compatible. Existing designs using RP164PJ3R3CS can transition to RAVF164DJT3R30 without circuit redesign or performance degradation.
