RF064PJ150CS Equivalent & Substitute Parts

Part Overview

The RF064PJ150CS is a 4-resistor isolated network array manufactured by Samsung Electro-Mechanics. This surface mount component features 15 Ohm resistors with ±5% tolerance and 31mW power per element in a 0502 (1406 Metric) package with long side terminals. The part is Active status and ROHS3 compliant, designed for applications requiring matched resistor networks in compact form factors. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution eligibility for the RF064PJ150CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 15 Ohms (exact match)
• Tolerance: ±5% (exact match)
• Number of resistors: 4 (exact match)
• Power per element: 31mW (exact match)
• Circuit type: Isolated (exact match)

Mechanical Equivalence Requirements:

• Package / Case: 0502 (1406 Metric), Long Side Terminals (exact match)
• Number of pins: 8 (exact match)
• Mounting type: Surface Mount (exact match)

Environmental & Compliance Requirements:

• Operating temperature range: -55°C ~ 125°C (exact match)
• RoHS Status: ROHS3 Compliant (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

The EXB-18V150JX from Panasonic Electronic Components meets all substitution criteria. Temperature coefficient variation (±200ppm/°C vs ±250ppm/°C) and maximum seated height difference (0.018" vs 0.013") are within acceptable engineering tolerances for this component category and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the RF064PJ150CS and EXB-18V150JX are Active status components with ROHS3 compliance and MSL 1 rating, indicating equivalent environmental handling and regulatory standing. The EXB-18V150JX offers improved temperature coefficient performance (±200ppm/°C vs ±250ppm/°C), which provides enhanced stability across the full operating temperature range of -55°C to 125°C. The maximum seated height difference of 0.005" (0.12mm) is negligible for surface mount assembly processes and does not impact PCB layout or component clearance in standard applications. Selection between these parts should be based on inventory availability, lead time requirements, and design margin preferences for temperature stability.

Frequently Asked Questions (FAQ)

Q: Can the EXB-18V150JX replace the RF064PJ150CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance values (15 Ohms), tolerance (±5%), element count (4), power rating (31mW per element), pin configuration (8 pins), and package dimensions (0502 with long side terminals). Both operate across -55°C to 125°C and meet ROHS3 compliance requirements.

Q: What is the significance of the temperature coefficient difference?

A: The EXB-18V150JX has a tighter temperature coefficient (±200ppm/°C) compared to the RF064PJ150CS (±250ppm/°C). This means the Panasonic part exhibits less resistance drift across temperature variations, providing superior stability in temperature-sensitive applications. This is a performance advantage, not a limitation.

Q: Does the height difference affect PCB assembly?

A: No. The maximum seated height difference is 0.005" (0.12mm), which is within standard PCB assembly tolerances and does not impact component placement, solder reflow profiles, or clearance requirements for typical applications.

Q: Are both parts available in the same packaging format?

A: Yes. Both the RF064PJ150CS and EXB-18V150JX are supplied in Tape & Reel (TR) packaging in the 0502 (1406 Metric) form factor with long side terminals, ensuring compatibility with standard surface mount assembly equipment.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.
