RF064PJ220CS Equivalent & Substitute Parts

Part Overview

The RF064PJ220CS is a 4-resistor isolated network array manufactured by Samsung Electro-Mechanics. This surface-mount component features 22 Ohm resistors with ±5% tolerance and 31mW power per element, housed in a 0502 (1406 Metric) package with long side terminals. The part is actively produced and ROHS3 compliant, making it suitable for applications requiring compact resistor networks with stable performance across industrial temperature ranges. Substitute parts are identified to address supply availability, inventory levels, or specific performance requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RF064PJ220CS is determined by strict alignment with the following critical parameters:

Electrical Parameters: Resistance value (22 Ohm), tolerance (±5%), number of resistors (4), circuit topology (Isolated), and power rating per element (31mW) must be identical. Temperature coefficient variation is acceptable provided the operating temperature range (-55°C ~ 125°C) is maintained or exceeded.

Mechanical Parameters: Package designation (0502 / 1406 Metric with long side terminals), pin count (8), and mounting type (Surface Mount) must match exactly to ensure PCB footprint compatibility and assembly process alignment.

Compliance Parameters: RoHS3 compliance status must be maintained. REACH and ECCN classifications are provided for regulatory reference but do not restrict substitution eligibility.

Inventory & Status: Product status (Active) ensures long-term availability. Substitute parts must also maintain Active status for production continuity.

The EXB-18V220JX from Panasonic Electronic Components qualifies as a direct substitute based on matching all critical electrical, mechanical, and compliance parameters.

Engineering Selection Recommendations

Primary Selection (RF064PJ220CS): Select the Samsung Electro-Mechanics RF064PJ220CS when supply is available and current inventory meets project timelines. This part maintains Active production status and full ROHS3 compliance.

Substitute Selection (EXB-18V220JX): The Panasonic Electronic Components EXB-18V220JX is a direct electrical and mechanical equivalent. Selection of this substitute is appropriate when:

• Samsung RF064PJ220CS inventory is unavailable or lead times exceed project requirements
• Panasonic supply chain offers superior availability (268,163 units in stock versus 1,000 units)
• The tighter temperature coefficient specification (±200ppm/°C versus ±250ppm/°C) provides performance advantage for temperature-sensitive applications
• PCB assembly processes accommodate the maximum seated height difference of 0.005" (0.12mm)

Both parts maintain identical electrical performance, package compatibility, and regulatory compliance. Selection between them is determined by supply availability and inventory status rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can EXB-18V220JX be used as a direct replacement for RF064PJ220CS on existing PCBs?

A: Yes. Both parts share identical package dimensions (0.055" L x 0.024" W), pin count (8), and footprint designation (0502 / 1406 Metric with long side terminals). The maximum seated height difference of 0.005" (0.12mm) is within standard PCB assembly tolerances and does not affect reflow soldering or component placement.

Q: Are there electrical performance differences between these parts?

A: Both parts deliver identical electrical specifications: 22 Ohm resistance, ±5% tolerance, 31mW power per element, and -55°C ~ 125°C operating range. The EXB-18V220JX features a tighter temperature coefficient (±200ppm/°C versus ±250ppm/°C), which represents improved stability across temperature extremes but does not affect functional compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both RF064PJ220CS and EXB-18V220JX are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is identical (MSL 1 / Unlimited) for both parts.

Q: What is the difference in inventory availability?

A: Samsung RF064PJ220CS has 1,000 units in current stock. Panasonic EXB-18V220JX has 268,163 units available. Substitute selection may be driven by project volume requirements and supply chain lead times.

Q: Are there any package or mounting differences?

A: No. Both parts are surface-mount components in 0502 (1406 Metric) packages with long side terminals and 8-pin configurations. Assembly processes, reflow profiles, and handling procedures are identical.

Q: Can these parts be mixed on the same PCB?

A: Yes. Both parts are electrically and mechanically equivalent. Mixed population on a single PCB does not create compatibility issues, though single-source procurement is recommended for manufacturing consistency and traceability.
