Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ432CS is determined by strict alignment with the following mandatory parameters:

Critical Matching Parameters:

• Resistance value: 4.3kΩ (exact match required)
• Tolerance: ±5% (exact match required)
• Number of resistors: 4 elements (exact match required)
• Circuit type: Isolated configuration (exact match required)
• Package designation: 1206 (3216 Metric) with convex, long side terminals (exact match required)
• Pin count: 8 pins (exact match required)
• Mounting type: Surface mount (exact match required)

Important Compatibility Parameters:

• Power per element: 62.5mW minimum (equal or higher acceptable)
• Temperature coefficient: ±200ppm/°C (equal or better acceptable)
• Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
• RoHS compliance: ROHS3 (equal or equivalent required)
• Moisture sensitivity: MSL 1 (equal or better acceptable)

The RAVF164DJT4K30 manufactured by Stackpole Electronics Inc qualifies as a direct substitute based on full alignment with all critical parameters and superior or equivalent performance in important parameters.

Engineering Selection Recommendations

The RAVF164DJT4K30 is a qualified direct substitute for the obsolete RP164PJ432CS based on the following engineering criteria:

Functional Equivalence: All critical electrical parameters match exactly, including resistance value, tolerance, circuit configuration, and temperature coefficient. The 4-element isolated resistor network architecture is identical, ensuring pin-for-pin compatibility and functional interchangeability in circuit applications.

Package Compatibility: Both components utilize identical 1206 (3216 Metric) surface mount packages with convex, long side terminals. Physical dimensions and pin configurations are equivalent, permitting direct PCB layout substitution without redesign.

Performance Enhancement: The RAVF164DJT4K30 provides 100mW power per element compared to 62.5mW in the original part, representing a 60% increase in thermal headroom. This enhancement improves reliability margins in power-dissipation-sensitive applications without introducing any compatibility issues.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements. Moisture sensitivity level 1 (unlimited) is identical, requiring no changes to storage or handling procedures.

Production Status: The substitute part is in active production with established supply chain availability, eliminating obsolescence risk associated with the original Samsung component.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT4K30 be used as a direct replacement for RP164PJ432CS without PCB modifications?

A: Yes. Both components share identical package dimensions (1206/3216 Metric), pinout configuration (8 pins), and terminal style (convex, long side). No PCB layout changes are required for substitution.

Q: What is the significance of the higher power rating (100mW vs 62.5mW) in the substitute part?

A: The increased power per element rating in the RAVF164DJT4K30 provides additional thermal margin during operation. This does not affect electrical performance but improves reliability in applications approaching the original part's power dissipation limits. The substitute will operate identically to the original in all standard applications.

Q: Are the tolerance and temperature coefficient specifications identical?

A: Yes. Both the RP164PJ432CS and RAVF164DJT4K30 specify ±5% tolerance and ±200ppm/°C temperature coefficient. Circuit accuracy and temperature stability characteristics are equivalent.

Q: Does the substitute part meet the same regulatory and compliance standards?

A: Yes. The RAVF164DJT4K30 is ROHS3 compliant and REACH unaffected, matching the original part's regulatory status. Moisture sensitivity level 1 (unlimited) is identical, requiring no changes to component handling or storage protocols.

Q: What is the primary advantage of selecting the RAVF164DJT4K30 over the obsolete RP164PJ432CS?

A: The Stackpole component is in active production with established supply chain availability, eliminating procurement risk. The original Samsung part is obsolete and subject to inventory depletion. Functionally and physically, both components are equivalent for circuit applications.

Q: Are there any electrical performance differences between these two 4.3kΩ resistor arrays?

A: No. Both components deliver identical electrical performance in terms of resistance value, tolerance, temperature coefficient, and operating temperature range. The only difference is the power per element rating, where the substitute provides enhanced thermal capability.
