Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ243CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 24kΩ
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit type: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Package / Case: 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: Substitute parts may exceed the original 62.5mW specification, provided the higher rating does not introduce thermal or reliability concerns in the application circuit
• Product status: Active alternatives are acceptable for obsolete parts
• Packaging format: Tape & Reel (TR) is compatible with the original packaging specification

The RAVF164DJT24K0 from Stackpole Electronics Inc meets all mandatory parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT24K0 is a direct functional equivalent to the RP164PJ243CS. Both components share identical electrical specifications for resistance value, tolerance, temperature coefficient, and operating temperature range. The physical package dimensions and pin configuration are equivalent, ensuring PCB layout compatibility without redesign.

The RAVF164DJT24K0 offers increased power dissipation capability (100mW per element versus 62.5mW), which provides additional thermal margin in applications operating at or near the original component's power rating limits. This higher power rating does not introduce incompatibility; it represents an enhancement in component robustness.

The substitute part carries active product status from Stackpole Electronics Inc, ensuring long-term availability and supply chain continuity. The component holds AEC-Q200 automotive qualification, indicating compliance with automotive-grade reliability standards. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT24K0 be used as a direct replacement for the RP164PJ243CS without PCB modifications?

A: Yes. Both components feature identical package dimensions (1206 / 3216 Metric), pin count (8), and terminal configuration (Convex, Long Side Terminals). 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 RAVF164DJT24K0 indicates higher thermal dissipation capability. This does not affect electrical performance in circuits designed for the original 62.5mW specification; it provides additional operational margin and thermal stability.

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

A: The RAVF164DJT24K0 carries AEC-Q200 automotive qualification, whereas the original RP164PJ243CS does not specify automotive qualification. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. The automotive qualification of the substitute part indicates enhanced reliability screening and qualification testing.

Q: Does the substitute part's active product status affect its suitability?

A: No. Active product status indicates ongoing manufacturing and availability. For obsolete original parts, active alternatives ensure long-term procurement viability and supply chain stability.

Q: Are the physical dimensions and height specifications identical?

A: Dimensions are equivalent: 0.126" L x 0.063" W (3.20mm x 1.60mm). Maximum seated height differs marginally (0.024" / 0.61mm for original versus 0.024" / 0.60mm for substitute), representing a negligible 0.01mm variation within standard manufacturing tolerances and PCB assembly clearance specifications.

Q: What packaging formats are available for the substitute part?

A: The RAVF164DJT24K0 is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly operations.
