Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCB410RJ is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Power dissipation capability: 4W minimum
• Temperature coefficient: -80/+40 ppm/°C or better

Mechanical Parameters:

• Package configuration: Radial through-hole
• Physical dimensions: 0.197" Dia × 0.953" L (5.00mm × 24.20mm)
• Termination count: 2-pin

Material & Compliance Parameters:

• Composition: Wirewound
• Flame retardant coating requirement
• Safety-rated construction
• RoHS3 compliance
• Operating temperature range: -55°C to +200°C minimum

Substitute parts must satisfy all electrical, mechanical, and compliance criteria simultaneously. No parameter relaxation or derating is permitted for valid substitution.

Engineering Selection Recommendations

The FCB410RJ is classified as obsolete. Direct equivalent substitution is limited to parts meeting identical electrical and mechanical specifications. Selection of alternative components must prioritize:

Compliance Verification:

• Confirmation of RoHS3 compliance status for the substitute part
• Validation of flame retardant coating and safety certifications
• Verification of operating temperature range support (-55°C to +200°C)

Mechanical Compatibility:

• Radial package configuration with identical lead spacing and diameter
• Physical dimensions matching 0.197" Dia × 0.953" L to ensure PCB layout compatibility
• Two-terminal through-hole configuration

Electrical Performance:

• Exact resistance value of 10 Ohms with ±5% tolerance
• Minimum 4W power rating capability
• Temperature coefficient within -80/+40 ppm/°C specification

Components failing to meet any single criterion are not suitable substitutes and will result in functional or reliability degradation.

Frequently Asked Questions (FAQ)

Q: Can a 10 Ohm resistor with different tolerance (e.g., ±10%) substitute for the FCB410RJ?

A: No. The FCB410RJ specifies ±5% tolerance. Substitutes with wider tolerances do not meet the electrical specification and are not equivalent.

Q: Is a 4W axial wirewound resistor compatible with the FCB410RJ?

A: No. The FCB410RJ requires radial package configuration. Axial packages have different lead geometry and cannot be directly substituted without PCB redesign.

Q: What if a substitute part has a lower operating temperature maximum (e.g., +150°C instead of +200°C)?

A: This does not constitute a valid substitute. The FCB410RJ specifies -55°C to +200°C operating range. Parts with reduced temperature capability do not meet the specification.

Q: Can the FCB410RJ be replaced with a film or carbon composition resistor of the same resistance and power rating?

A: No. The FCB410RJ is wirewound composition with flame retardant coating and safety features. Alternative compositions do not provide equivalent thermal stability, temperature coefficient performance, or safety certification.

Q: Are there any mechanical considerations for PCB mounting when substituting this resistor?

A: Yes. The substitute must maintain identical radial lead spacing and diameter (0.197" Dia) to ensure compatibility with existing PCB footprints. Physical dimensions of 0.197" Dia × 0.953" L must be preserved.

Q: Does RoHS3 compliance status affect substitution eligibility?

A: Yes. Both the main part and substitute must maintain RoHS3 compliance status. Compliance downgrades are not permitted.
