Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ154CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 150k Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 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: May exceed the original 62.5mW specification (higher power rating provides design margin)
• Product status: Active status preferred over obsolete
• Packaging format: Tape & Reel acceptable as alternative to standard packaging
• Manufacturer: Different manufacturers permitted if all electrical and mechanical parameters align

The RAVF164DJT150K from Stackpole Electronics Inc qualifies as a direct substitute, meeting all mandatory parameters while providing increased power dissipation capability (100mW per element versus 62.5mW).

Engineering Selection Recommendations

Primary Substitute: RAVF164DJT150K

The RAVF164DJT150K is the qualified equivalent for RP164PJ154CS replacement. Selection rationale:

1. Electrical Equivalence: All critical electrical parameters match exactly, including resistance value, tolerance, temperature coefficient, and operating temperature range.

2. Mechanical Compatibility: Package dimensions, pin configuration, and mounting type are identical, enabling direct PCB footprint compatibility without layout modification.

3. Product Status Advantage: Active manufacturing status ensures long-term availability and supply chain continuity, addressing the obsolescence limitation of the original part.

4. Compliance Alignment: Both components maintain ROHS3 compliance and MSL 1 rating, preserving environmental and reliability certifications.

5. Power Dissipation Margin: The increased power rating (100mW versus 62.5mW per element) provides additional thermal headroom without introducing design risk.

6. Automotive Qualification: RAVF164DJT150K carries AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade component reliability.

Frequently Asked Questions (FAQ)

Q: Can RAVF164DJT150K be used as a direct replacement for RP164PJ154CS without PCB modification?

A: Yes. Both components share identical package dimensions (1206 / 3216 Metric), pin count (8), and terminal configuration (Convex, Long Side Terminals). No PCB layout changes are required.

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

A: The increased power dissipation capability of RAVF164DJT150K provides additional thermal margin during operation. This does not alter electrical performance but allows the component to operate safely in applications with higher current demands without exceeding temperature limits.

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

A: Both parts maintain ROHS3 compliance and MSL 1 rating. The RAVF164DJT150K additionally carries AEC-Q200 automotive qualification, which is a superset qualification suitable for automotive and industrial applications.

Q: Does the packaging format difference (Tape & Reel for RAVF164DJT150K) affect compatibility?

A: No. Tape & Reel is a supply format for automated assembly processes. The component itself is identical to standard packaging formats. Verify your assembly equipment compatibility with Tape & Reel format if this is a concern for your manufacturing process.

Q: What is the temperature coefficient, and why is matching important?

A: Temperature coefficient (±200ppm/°C) specifies how resistance changes with temperature. Matching this parameter ensures predictable circuit behavior across the operating temperature range (-55°C ~ 155°C). Both parts are equivalent in this specification.

Q: Can I use other resistor array manufacturers as substitutes?

A: Only components meeting all mandatory parameters listed in the Substitute Part Grouping Explanation section qualify as direct substitutes. Verify resistance value, tolerance, circuit type (isolated), package type, and all electrical specifications before selecting alternatives.
