Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ272CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.7k Ohm
• 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

Allowable Variation:

• Power per element: Substitute parts may exceed the original 62.5mW specification, provided the higher power rating does not introduce thermal or reliability concerns in the application circuit.

The RAVF164DJT2K70 from Stackpole Electronics Inc qualifies as a direct substitute, meeting all mandatory parameters while providing increased power dissipation capability (100mW per element). Both components maintain identical mechanical dimensions, electrical characteristics, and environmental compliance ratings.

Engineering Selection Recommendations

The RAVF164DJT2K70 is the qualified substitute for the obsolete RP164PJ272CS. Selection rationale is based on the following engineering factors:

Product Status: The RP164PJ272CS is classified as obsolete, creating supply chain risk. The RAVF164DJT2K70 maintains active production status, ensuring long-term availability and supply continuity.

Compliance and Certification: Both components achieve ROHS3 compliance and maintain REACH unaffected status. The RAVF164DJT2K70 carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Electrical Equivalence: Identical resistance, tolerance, temperature coefficient, and operating temperature range ensure functional interchangeability in circuit applications. The increased power per element (100mW versus 62.5mW) represents a design margin improvement without introducing incompatibility.

Mechanical Compatibility: Identical package dimensions, pin count, and mounting type enable direct PCB-level substitution without layout modifications or rework.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT2K70 be used as a direct replacement for the RP164PJ272CS in existing designs?

A: Yes. The RAVF164DJT2K70 meets all electrical and mechanical specifications required for direct substitution. Identical package type, pin configuration, resistance value, tolerance, and temperature characteristics ensure functional equivalence. No circuit redesign or PCB modification is required.

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 RAVF164DJT2K70 provides additional thermal headroom and design margin. This higher rating does not create incompatibility; it represents an improvement in power dissipation capability. Applications operating within the original 62.5mW specification will experience no adverse effects.

Q: Are there packaging differences between the two parts?

A: Both components use identical 1206 (3216 Metric) surface mount packages with convex, long side terminals. Physical dimensions are equivalent (0.126" L x 0.063" W), with negligible height variation (0.61mm vs. 0.60mm). No packaging-related compatibility issues exist.

Q: What compliance certifications apply to the substitute part?

A: The RAVF164DJT2K70 is ROHS3 compliant and REACH unaffected. It carries AEC-Q200 automotive qualification, meeting automotive industry reliability standards. Both components maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Why is the original RP164PJ272CS classified as obsolete?

A: Obsolescence reflects Samsung Electro-Mechanics' discontinuation of this product line. The RAVF164DJT2K70 from Stackpole Electronics Inc provides equivalent functionality with active production status, ensuring ongoing supply availability and support.

Q: Are there any thermal or reliability concerns when substituting the RAVF164DJT2K70?

A: No thermal or reliability concerns exist. Both components operate across identical temperature ranges (-55°C to 155°C) with matching temperature coefficients (±200ppm/°C). The substitute part's higher power rating enhances thermal performance rather than introducing risk.
