Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ393CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 39kΩ
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Mounting type: Surface Mount
• Physical dimensions: 0.126" L × 0.063" W (3.20mm × 1.60mm)

Allowable Variation:

• Power per element: Substitute parts with equal or greater power rating are acceptable, as higher power dissipation capability does not compromise circuit function
• Product status: Active status substitutes are preferred for obsolete parts to ensure supply continuity

The RAVF164DJT39K0 from Stackpole Electronics Inc meets all mandatory parameters and exceeds the power specification, qualifying as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT39K0 is a qualified substitute for the obsolete RP164PJ393CS based on the following engineering criteria:

Compliance & Regulatory Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Product Status Advantage: The RAVF164DJT39K0 carries active product status, providing supply security and long-term availability compared to the obsolete RP164PJ393CS. This status transition is critical for production continuity.

Electrical Parameter Equivalence: Identical resistance value (39kΩ), tolerance (±5%), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 155°C) ensure functional equivalence in circuit applications.

Power Dissipation Enhancement: The RAVF164DJT39K0 provides 100mW per element versus 62.5mW in the original part. This increased power rating expands thermal margin without affecting electrical performance, as the substitute operates within the same temperature coefficient and range specifications.

Mechanical & Package Compatibility: Identical package configuration (1206 Convex, Long Side Terminals), pin count (8), and physical dimensions (0.126" × 0.063" × 0.024" max height) ensure direct PCB compatibility without layout modifications.

Automotive Qualification: The RAVF164DJT39K0 carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT39K0 directly replace the RP164PJ393CS without PCB modifications?

A: Yes. Both parts share identical package type (1206 Convex, Long Side Terminals), pin configuration (8 pins), and physical dimensions (0.126" L × 0.063" W, 0.024" max height). Direct PCB substitution is supported without layout changes.

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

A: The increased power per element in the RAVF164DJT39K0 provides additional thermal dissipation capacity. This does not alter electrical performance but expands the operational margin for applications with higher power demands. The substitute remains within the same temperature coefficient (±200ppm/°C) and operating range (-55°C to 155°C).

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: Why is the RAVF164DJT39K0 preferred over the obsolete RP164PJ393CS?

A: The RAVF164DJT39K0 carries active product status, ensuring long-term supply availability and manufacturing support. The RP164PJ393CS is obsolete, creating supply risk and potential discontinuation. For new designs and ongoing production, the active substitute is the appropriate selection.

Q: Does the AEC-Q200 qualification of the RAVF164DJT39K0 affect its use in non-automotive applications?

A: No. AEC-Q200 qualification indicates automotive-grade reliability testing and is not restrictive. The part functions identically in industrial, commercial, and consumer applications. The qualification represents an additional quality assurance level.

Q: Are the electrical parameters (resistance, tolerance, temperature coefficient) identical between the two parts?

A: Yes. Both parts specify 39kΩ ±5% resistance with ±200ppm/°C temperature coefficient. Electrical performance is equivalent across the full operating temperature range (-55°C to 155°C).

Q: What is the difference in packaging between the two parts?

A: The RP164PJ393CS is supplied in standard packaging, while the RAVF164DJT39K0 is supplied in Tape & Reel (TR) format. Both use identical component packaging (1206 Convex, Long Side Terminals). The difference is in the delivery format for manufacturing automation.
