Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCB15KB10R0 is determined by the following critical parameters:

• Resistance Value: Must be 10 Ohms
• Power Rating: Must be 15W minimum
• Package Type: Must be Axial for mechanical and electrical compatibility
• Composition: Wirewound construction required
• Operating Temperature Range: Must support -55°C to 275°C
• Safety Features: Flame Proof and Moisture Resistant characteristics required
• Compliance: ROHS3 compliance mandatory

The CB15JB10R0 qualifies as a direct substitute based on matching all critical parameters while offering improved tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

The CB15JB10R0 is the qualified substitute for the obsolete PCB15KB10R0. Both parts maintain identical electrical specifications for resistance value, power rating, and operating temperature range. The substitute offers improved tolerance (±5% versus ±10%) and superior temperature coefficient performance (±200ppm/°C versus ±800ppm/°C), providing enhanced circuit stability without compromising compatibility.

The CB15JB10R0 maintains active product status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete PCB15KB10R0. Both parts carry ROHS3 compliance and identical safety certifications, ensuring regulatory continuity in applications requiring flame-proof and moisture-resistant characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CB15JB10R0 be used as a direct replacement for PCB15KB10R0 in existing designs?

A: Yes. The CB15JB10R0 meets all electrical and mechanical requirements for direct substitution. The improved tolerance and temperature coefficient represent performance enhancements rather than deviations from the original specification.

Q: What is the significance of the tolerance difference between ±10% and ±5%?

A: The ±5% tolerance of the CB15JB10R0 provides tighter resistance value control, resulting in more predictable circuit behavior. This is a beneficial characteristic for precision applications and does not create compatibility issues.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use axial packaging. The PCB15KB10R0 measures 1.902" L x 0.500" W, while the CB15JB10R0 measures 0.512" Square x 1.890" L. Both fit standard axial component footprints and mounting positions.

Q: What compliance certifications apply to both parts?

A: Both the PCB15KB10R0 and CB15JB10R0 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain identical safety feature certifications for flame-proof and moisture-resistant operation.

Q: Why is the PCB15KB10R0 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The CB15JB10R0 represents the active equivalent within the Stackpole CB series, ensuring continued availability for new production and field replacements.
