EXB-F6WT06G Equivalent & Substitute Parts

Part Overview

The EXB-F6WT06G is an 8-resistor network array manufactured by Panasonic Electronic Components, configured as a dual terminator with 330 and 470 ohm resistance values. This through-hole mounted component operates across the industrial temperature range of -55°C to 125°C with ±2% tolerance and 125mW power per element. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new production runs requiring compatible drop-in replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EXB-F6WT06G is determined by strict alignment of the following critical parameters:

• Circuit Configuration: Dual terminator topology with 8 resistors in 6-SIP package
• Resistance Values: 330 and 470 ohm values must be present
• Tolerance: ±2% tolerance specification
• Pin Count and Package: 6-pin SIP package for through-hole mounting
• Operating Temperature Range: -55°C to 125°C minimum requirement
• Physical Compatibility: Package dimensions and height must accommodate existing PCB layouts

The substitute part 4306R-104-331/471 from Bourns Inc. meets all these core substitution criteria. While the substitute offers enhanced specifications in power rating and temperature coefficient, these represent improvements that maintain backward compatibility with the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

The 4306R-104-331/471 from Bourns Inc. is the qualified substitute for the obsolete EXB-F6WT06G. Selection of this alternative is supported by the following factors:

Product Status: The Bourns component maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete Panasonic part.

Electrical Compatibility: Both components share identical resistance values (330, 470 ohms), tolerance (±2%), pin count (6), and operating temperature range (-55°C to 125°C). The Bourns substitute provides superior performance specifications with 200mW power per element versus 125mW, and a tighter temperature coefficient of ±100ppm/°C versus ±200ppm/°C.

Physical Compatibility: Package dimensions are nearly identical with maximum seated height of 0.195" for both parts, ensuring direct PCB layout compatibility without redesign.

Compliance Considerations: The Bourns component is REACH Affected and RoHS non-compliant. Design teams must evaluate these compliance requirements against project specifications and regional regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 4306R-104-331/471 be used as a direct replacement for the EXB-F6WT06G?

A: Yes. Both components share the same dual terminator circuit configuration, 330/470 ohm resistance values, ±2% tolerance, 6-pin SIP package, and operating temperature range. Physical dimensions are compatible with existing through-hole PCB layouts.

Q: What are the key differences between these two parts?

A: The primary differences are product status (Panasonic is obsolete; Bourns is active), power rating per element (125mW versus 200mW), and temperature coefficient (±200ppm/°C versus ±100ppm/°C). The Bourns substitute offers improved thermal stability and higher power dissipation capability.

Q: Are there any physical compatibility concerns?

A: No. Both components use the 6-SIP through-hole package with identical maximum seated height of 0.195". Horizontal dimensions are nearly identical (14.88mm versus 14.83mm length; 2.54mm versus 2.16mm width), presenting no PCB layout issues.

Q: What compliance differences exist between these parts?

A: The Panasonic EXB-F6WT06G has MSL rating of 1 (Unlimited). The Bourns 4306R-104-331/471 is REACH Affected and RoHS non-compliant. Projects with specific compliance requirements must evaluate these certifications against design specifications.

Q: Is the higher power rating of the Bourns part a concern?

A: No. The 200mW power per element rating of the Bourns component exceeds the 125mW requirement of the original design, providing additional thermal margin and improved reliability without introducing compatibility issues.
