Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ431CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 430 Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Number of pins: 8
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Mounting type: Surface Mount

Allowable Variation Parameters:

• Power per element: Substitute must meet or exceed 62.5mW minimum
• Product status: Active status preferred for long-term availability
• Packaging format: May differ (Tape & Reel acceptable for procurement)
• Compliance certifications: Additional qualifications (such as AEC-Q200) are permissible

The RAVF164DJT430R from Stackpole Electronics Inc qualifies as a direct substitute based on full alignment with all mandatory parameters and superior power rating (100mW per element).

Engineering Selection Recommendations

Primary Substitute: RAVF164DJT430R

The RAVF164DJT430R is the qualified substitute for the obsolete RP164PJ431CS. Selection rationale is based on the following engineering factors:

Compliance & Regulatory:

• Both parts maintain ROHS3 compliance and REACH unaffected status
• RAVF164DJT430R carries AEC-Q200 automotive qualification, providing additional reliability assurance for demanding applications

Product Lifecycle:

• RP164PJ431CS is obsolete; RAVF164DJT430R is active, ensuring long-term availability and manufacturing continuity
• Active status eliminates supply chain risk associated with end-of-life components

Electrical Performance:

• Identical resistance, tolerance, temperature coefficient, and operating temperature range
• RAVF164DJT430R power rating (100mW per element) exceeds the original specification (62.5mW per element), providing thermal margin and enhanced reliability

Physical Compatibility:

• Identical package footprint, pin count, and terminal configuration
• Seated height differential (0.60mm vs 0.61mm) is negligible for PCB assembly and does not affect placement or clearance

Procurement:

• RAVF164DJT430R is available in Tape & Reel packaging, standard for automated assembly operations

The RAVF164DJT430R substitution requires no circuit redesign and is suitable for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT430R be used as a direct drop-in replacement for the RP164PJ431CS?

A: Yes. The RAVF164DJT430R is electrically and mechanically compatible with the RP164PJ431CS. Both parts share identical resistance value, tolerance, temperature coefficient, operating temperature range, pin count, and 1206 package configuration. The substitute's higher power rating (100mW vs 62.5mW per element) provides additional thermal capability without affecting circuit operation.

Q: What is the significance of the AEC-Q200 qualification on the RAVF164DJT430R?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. While the original RP164PJ431CS does not specify this qualification, the RAVF164DJT430R's AEC-Q200 status indicates enhanced reliability testing and quality assurance, making it suitable for both automotive and general industrial applications.

Q: Are there any PCB layout or assembly considerations when switching from RP164PJ431CS to RAVF164DJT430R?

A: No layout modifications are required. Both parts use identical 1206 (3216 Metric) package dimensions (0.126" L x 0.063" W) with convex, long side terminals. The seated height difference (0.61mm vs 0.60mm) is within standard PCB assembly tolerances and does not affect component placement, solder reflow, or clearance requirements.

Q: Why is the RP164PJ431CS listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Samsung Electro-Mechanics and is not available through standard distribution channels. The RAVF164DJT430R from Stackpole Electronics Inc is the active equivalent, ensuring continued availability for new designs and production support.

Q: Does the higher power rating of the RAVF164DJT430R affect circuit performance?

A: No. The higher power rating (100mW vs 62.5mW per element) represents increased thermal capacity and does not alter electrical characteristics. Resistance, tolerance, and temperature coefficient remain identical. The enhanced power rating provides additional design margin and improved reliability under thermal stress.

Q: What packaging formats are available for the RAVF164DJT430R?

A: The RAVF164DJT430R is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly. This packaging format is compatible with standard pick-and-place equipment and reflow soldering processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the RP164PJ431CS and RAVF164DJT430R are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
