Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ621CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 620 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Pin count: 8
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Mounting technology: Surface Mount

Allowable Variation:

• Power per element rating may exceed the original specification (higher power rating provides enhanced margin)
• Product status may differ (active status preferred for long-term availability)
• Packaging format (Tape & Reel acceptable for manufacturing environments)

The RAVF164DJT620R 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).

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT620R is the qualified substitute for the obsolete RP164PJ621CS. Selection rationale is based on the following engineering factors:

Functional Equivalence: Both components share identical electrical specifications for resistance value, tolerance, temperature coefficient, and operating temperature range. The isolated four-resistor configuration and pin assignment are identical, ensuring direct functional replacement in circuit applications.

Enhanced Reliability Margin: The RAVF164DJT620R provides 100mW power per element compared to the original 62.5mW specification. This increased power rating creates additional thermal margin in applications operating near maximum power dissipation limits.

Active Product Status: The RAVF164DJT620R maintains active production status with Stackpole Electronics Inc, ensuring long-term availability and supply chain continuity. The RP164PJ621CS obsolete status necessitates transition to an alternative source.

Compliance Alignment: Both components maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity classification (MSL 1), ensuring regulatory and environmental compatibility.

Automotive Qualification: The RAVF164DJT620R carries AEC-Q200 automotive qualification and automotive grade designation, providing additional quality assurance for applications requiring automotive-level reliability standards.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT620R be used as a direct replacement for the RP164PJ621CS in existing designs?

A: Yes. The RAVF164DJT620R is a direct functional substitute. Both components share identical resistance value (620 Ohm), tolerance (±5%), package configuration (1206 Convex, Long Side Terminals), pin count (8), circuit type (Isolated), and operating temperature range (-55°C ~ 155°C). No circuit modifications are 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 rating in the RAVF164DJT620R provides additional thermal dissipation capability. This allows the component to operate safely in applications where the original part approached its power limit. The higher rating does not affect electrical performance in applications operating below the original 62.5mW specification.

Q: Are there any compatibility concerns with PCB assembly equipment?

A: No. Both components use identical surface mount technology and 1206 package dimensions (3.20mm x 1.60mm). Existing pick-and-place programming, solder reflow profiles, and PCB footprints require no modification.

Q: Does the RAVF164DJT620R meet the same environmental and regulatory standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity). The RAVF164DJT620R additionally carries AEC-Q200 automotive qualification, exceeding the original specification.

Q: What is the difference between the Samsung RP series and Stackpole RAVF series?

A: Both are isolated resistor array networks with identical electrical and mechanical specifications for this 620 Ohm configuration. The primary differences are manufacturer source and product status. The Stackpole RAVF series maintains active production, while the Samsung RP series is obsolete.

Q: Can multiple RAVF164DJT620R units be mixed with remaining RP164PJ621CS inventory in production?

A: Yes. Both components are electrically and mechanically identical for the specified parameters. Mixed inventory can be used interchangeably without affecting circuit performance or reliability.
