Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ184CS is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 180k Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Pin count: 8
• Mounting type: Surface Mount
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Allowable Variation Parameters:

• Power per element: Substitute parts may exceed the original 62.5mW specification, provided the higher rating does not introduce thermal or reliability concerns in the application context
• Packaging format: Original part is supplied in standard packaging; substitutes may be supplied in Tape & Reel (TR) format
• Manufacturer: Different manufacturers are acceptable provided all electrical and mechanical parameters align

The RAVF164DJT180K from Stackpole Electronics Inc qualifies as a direct substitute based on full alignment of all mandatory parameters and allowable variation within power rating specifications.

Engineering Selection Recommendations

Primary Substitute: RAVF164DJT180K

The RAVF164DJT180K from Stackpole Electronics Inc is the qualified equivalent for RP164PJ184CS replacement. Selection rationale is based on the following engineering factors:

Compliance and Certification:

• Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards
• RAVF164DJT180K carries AEC-Q200 automotive qualification, providing enhanced reliability documentation suitable for mission-critical applications
• Moisture sensitivity level remains at MSL 1 (Unlimited) for both parts, eliminating moisture-related handling constraints

Product Status Advantage:

• RP164PJ184CS is classified as obsolete, creating long-term procurement risk and potential supply discontinuation
• RAVF164DJT180K maintains active product status with established supply chain availability, ensuring sustained component sourcing for design lifecycle support

Electrical Performance:

• All critical electrical parameters align identically: 180k Ohm resistance, ±5% tolerance, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range
• Power per element specification increases from 62.5mW to 100mW in the substitute part, representing a 60% margin increase that enhances thermal headroom without introducing design incompatibility

Physical and Mechanical Compatibility:

• Package footprint, pin configuration, and mounting type are identical, enabling direct PCB layout compatibility
• Seated height differential of 0.01mm (0.61mm vs 0.60mm) is negligible for surface mount assembly processes

Packaging Format:

• Original part supplied in standard packaging; substitute available in Tape & Reel (TR) format, supporting automated assembly workflows and reducing component handling costs

Frequently Asked Questions (FAQ)

Q: Can RAVF164DJT180K be used as a direct replacement for RP164PJ184CS without PCB modifications?

A: Yes. Both parts share identical package type (1206 Convex, Long Side Terminals), pin count (8), and physical dimensions (0.126" L x 0.063" W). PCB layout and footprint remain unchanged. No design modifications are required.

Q: What is the significance of the power per element increase from 62.5mW to 100mW?

A: The higher power rating in RAVF164DJT180K provides additional thermal margin and does not introduce incompatibility. If the original design operated at or below 62.5mW per element, the substitute part will operate at lower relative stress levels, improving reliability margins.

Q: Why is product status (Obsolete vs. Active) important for component selection?

A: Obsolete parts face supply discontinuation risk and potential manufacturing process changes. Active products maintain stable supply chains, consistent manufacturing specifications, and long-term availability. RAVF164DJT180K's active status ensures sustained procurement capability throughout the design lifecycle.

Q: Are there any temperature or environmental performance differences between these parts?

A: No. Both parts specify identical operating temperature range (-55°C to 155°C) and temperature coefficient (±200ppm/°C). Environmental performance characteristics are equivalent.

Q: Does the Tape & Reel packaging format of RAVF164DJT180K affect compatibility?

A: No. Tape & Reel is a supply format that improves automated assembly efficiency. The component itself remains identical in electrical and mechanical specifications. Packaging format does not affect PCB-level performance or compatibility.

Q: What does AEC-Q200 qualification on RAVF164DJT180K indicate?

A: AEC-Q200 is an automotive industry standard qualification demonstrating enhanced reliability testing and quality assurance. While the original RP164PJ184CS does not carry this designation, RAVF164DJT180K's qualification provides additional reliability documentation suitable for applications requiring automotive-grade component assurance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RP164PJ184CS and RAVF164DJT180K maintain ROHS3 compliance and REACH unaffected status, ensuring alignment with current environmental and regulatory requirements.

Q: Can these parts be used interchangeably in existing inventory systems?

A: Yes, provided inventory management systems are updated to reflect the manufacturer change from Samsung Electro-Mechanics to Stackpole Electronics Inc. The electrical and mechanical equivalence supports direct substitution in component databases and bill of materials records.
