Engineering Selection Recommendations
Primary Part: RF064PJ180CS (Samsung Electro-Mechanics)
The RF064PJ180CS is the specified component with Active product status and full ROHS3 compliance. Current inventory of 1,074 pieces supports immediate procurement.
Approved Substitute: EXB-18V180JX (Panasonic Electronic Components)
The EXB-18V180JX qualifies as a direct substitute based on electrical and mechanical equivalence. Key selection factors:
- All critical electrical parameters match: 18 Ohm resistance, ±5% tolerance, 4-element isolated configuration, 31mW per element
- Mechanical compatibility confirmed: identical 0502 package footprint, 8-pin configuration, surface mount technology
- Compliance alignment: ROHS3 compliant, MSL Level 1 (Unlimited)
- Temperature coefficient of ±200ppm/°C represents improved thermal stability compared to the primary part specification of ±250ppm/°C
- Maximum seated height of 0.018" (0.45mm) versus 0.013" (0.33mm) on primary part remains within acceptable PCB assembly clearance for 0502 packages
- Higher inventory availability (10,719 pieces) supports supply chain continuity
Both parts are Active status with equivalent regulatory compliance and are suitable for direct substitution in circuit applications requiring 18 Ohm isolated resistor networks.
Frequently Asked Questions (FAQ)
Q: Can the EXB-18V180JX replace the RF064PJ180CS in existing designs?
A: Yes. The EXB-18V180JX meets all critical electrical and mechanical specifications. Both components feature identical 18 Ohm resistance, ±5% tolerance, 4-element isolated configuration, 31mW power per element, and 0502 package with 8 pins. Operating temperature range and compliance certifications are equivalent.
Q: What is the significance of the temperature coefficient difference (±250ppm/°C vs ±200ppm/°C)?
A: The EXB-18V180JX exhibits a tighter temperature coefficient specification at ±200ppm/°C compared to the RF064PJ180CS at ±250ppm/°C. This represents improved thermal stability and is acceptable for substitution purposes, as it meets or exceeds the performance requirement.
Q: Are there physical compatibility concerns with the height difference?
A: The EXB-18V180JX has a maximum seated height of 0.018" (0.45mm) versus 0.013" (0.33mm) for the RF064PJ180CS. This 0.005" (0.12mm) difference is within standard PCB assembly tolerances for 0502 packages and does not present compatibility issues for typical surface mount applications.
Q: Do both parts require identical handling and storage procedures?
A: Both components share identical Moisture Sensitivity Level (MSL) classification of Level 1 (Unlimited), indicating no moisture sensitivity concerns. Standard ESD precautions and dry storage conditions apply to both parts.
Q: What packaging format is available for both parts?
A: Both the RF064PJ180CS and EXB-18V180JX are supplied in Tape & Reel (TR) format, standard for surface mount resistor networks in production environments.
Q: Are there any regulatory or compliance differences between the two parts?
A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent, supporting direct substitution in applications with environmental compliance requirements.
