Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCB7JB75R0 is determined by the following critical parameters:

• Resistance value: 75 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 7W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Features: Flame Proof, Moisture Resistant, Safety (exact match required)
• Operating temperature range: -55°C to 275°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The CB7JB75R0 meets all substitution criteria as a direct equivalent from the same manufacturer, with identical electrical specifications and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

The CB7JB75R0 is the direct substitute for the obsolete PCB7JB75R0. Both components are manufactured by Stackpole Electronics Inc and share identical electrical and mechanical specifications across all critical parameters: 75 Ohm resistance, ±5% tolerance, 7W power rating, wirewound composition, axial package, and full operating temperature range of -55°C to 275°C. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility.

The CB7JB75R0 is currently in active production status with confirmed inventory availability, making it the appropriate selection for new designs and production requirements where the PCB7JB75R0 is no longer obtainable.

Frequently Asked Questions (FAQ)

Q: Can the CB7JB75R0 be used as a direct replacement for the PCB7JB75R0?

A: Yes. The CB7JB75R0 is a direct equivalent with identical electrical specifications (75 Ohms, ±5%, 7W), composition (wirewound), package type (axial), and operating characteristics (-55°C to 275°C). Both components are ROHS3 compliant and manufactured by Stackpole Electronics Inc.

Q: What is the difference between the PCB7JB75R0 and CB7JB75R0?

A: The primary differences are product status and temperature coefficient. The PCB7JB75R0 is obsolete with a temperature coefficient of ±800ppm/°C, while the CB7JB75R0 is active with an improved temperature coefficient of ±200ppm/°C. Physical dimensions are nominally equivalent within standard manufacturing tolerances.

Q: Are there any packaging differences between these parts?

A: Both components use axial through-hole packaging. Dimensional specifications are within standard manufacturing tolerances for wirewound resistors of this class, with no functional impact on circuit board layout or assembly.

Q: Is the CB7JB75R0 suitable for applications requiring flame-proof and moisture-resistant construction?

A: Yes. The CB7JB75R0 maintains the same flame-proof, moisture-resistant, and safety-rated construction as the PCB7JB75R0, making it suitable for identical application requirements.

Q: What compliance certifications apply to the CB7JB75R0?

A: The CB7JB75R0 is ROHS3 compliant and REACH unaffected, matching the regulatory status of the PCB7JB75R0.
