Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP164PJ183CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 18kΩ
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Number of pins: 8
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Package format: 1206 (3216 Metric), Convex, Long Side Terminals
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Mounting type: Surface Mount

Allowable Variation Parameters:

• Power per element: Substitute parts may exceed the 62.5mW specification of the main part, provided all other parameters remain equivalent
• Product status: Active alternatives are acceptable for obsolete parts
• Packaging format: Variations in supplier packaging (e.g., Tape & Reel vs. bulk) do not affect functional equivalence
• Certifications and compliance: Additional qualifications (e.g., AEC-Q200, automotive grade) represent enhanced specifications

The RAVF164DJT18K0 manufactured by Stackpole Electronics Inc meets all mandatory matching parameters and qualifies as a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT18K0 is a direct functional equivalent to the obsolete RP164PJ183CS. Selection of this substitute is based on the following engineering criteria:

Functional Equivalence: All mandatory electrical and mechanical parameters are identical between the two parts. The 18kΩ resistance value, ±5% tolerance, isolated 4-element configuration, 8-pin count, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range are preserved.

Package Compatibility: Both parts utilize identical 1206 (3216 Metric) surface mount packages with convex, long-side terminal configuration. Physical dimensions and maximum seated height are equivalent, ensuring PCB layout and assembly compatibility without modification.

Compliance Status: The RAVF164DJT18K0 maintains ROHS3 compliance and MSL 1 rating, matching the environmental and regulatory requirements of the original part. The substitute additionally carries AEC-Q200 automotive qualification, representing an enhanced specification level suitable for automotive and high-reliability applications.

Power Rating Enhancement: The RAVF164DJT18K0 provides 100mW power per element compared to the 62.5mW specification of the RP164PJ183CS. This represents a performance enhancement that does not compromise compatibility; circuits designed for the original part will operate within the thermal and electrical envelope of the substitute.

Product Status: The transition from an obsolete Samsung part to an active Stackpole product ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT18K0 be used as a direct replacement for the RP164PJ183CS without PCB modification?

A: Yes. Both parts share identical package geometry (1206 / 3216 Metric), pin count (8), terminal configuration (convex, long-side), and physical dimensions (0.126" L x 0.063" W, 0.024" max height). No PCB layout changes are required.

Q: What is the significance of the higher power rating (100mW vs. 62.5mW) in the RAVF164DJT18K0?

A: The increased power per element rating indicates enhanced thermal capability. Circuits designed for the original 62.5mW specification will operate with additional thermal margin when using the 100mW-rated substitute. This does not create compatibility issues; it represents a performance improvement.

Q: Are there differences in electrical performance between these parts?

A: No. Both parts specify identical resistance (18kΩ), tolerance (±5%), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 155°C). Electrical behavior in circuit applications is equivalent.

Q: What does the AEC-Q200 qualification on the RAVF164DJT18K0 indicate?

A: AEC-Q200 is an automotive industry qualification standard. The RAVF164DJT18K0 meets automotive-grade reliability and testing requirements. This qualification is not present on the original RP164PJ183CS but does not prevent use of the substitute in non-automotive applications.

Q: Does packaging format (Tape & Reel vs. bulk) affect component functionality?

A: No. Packaging format affects only procurement and handling logistics. The Tape & Reel (TR) packaging of the RAVF164DJT18K0 is a supplier packaging option that does not alter the component's electrical or mechanical characteristics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RP164PJ183CS and RAVF164DJT18K0 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting equivalent environmental and regulatory standards.
