CB3JB4R70 Equivalent & Substitute Parts

Part Overview

The CB3JB4R70 is a 4.7 Ohm, 3W wirewound axial resistor manufactured by Stackpole Electronics Inc. This through-hole component features flame-proof and moisture-resistant construction with a ±5% tolerance and operates across a wide temperature range of -55°C to 275°C. The part maintains Active product status with 1003 units currently in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to availability constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CB3JB4R70 are qualified based on the following critical parameters:

• Electrical Equivalence: Resistance value of 4.7 Ohms with ±5% tolerance
• Power Rating: 3W minimum capacity
• Package Configuration: Axial through-hole form factor
• Composition: Wirewound construction
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected status
• Termination Count: 2-terminal configuration

The identified substitutes PNP300JR-73-4R7 and PNP3WVJR-73-4R7 (both YAGEO manufacture) meet all core electrical and mechanical requirements. Differences in physical dimensions, temperature coefficient specification availability, and operating temperature upper limits are noted but do not preclude substitution in applications where the CB3JB4R70 specifications are required.

Parameter Comparison

Engineering Selection Recommendations

Both YAGEO substitutes maintain Active product status and full regulatory compliance (ROHS3 and REACH). Selection between CB3JB4R70 and its substitutes should be based on application-specific temperature requirements. The CB3JB4R70 supports extended high-temperature operation to 275°C, while PNP300JR-73-4R7 and PNP3WVJR-73-4R7 are rated to 200°C maximum. For applications operating within -40°C to 200°C, either YAGEO substitute provides electrical and mechanical equivalence. For applications requiring operation above 200°C, the CB3JB4R70 is the appropriate selection. Physical dimensions vary across the three parts; PCB layout and mechanical clearance must be verified during substitution.

Frequently Asked Questions (FAQ)

Q: Can PNP300JR-73-4R7 or PNP3WVJR-73-4R7 be used as direct replacements for CB3JB4R70?

A: Yes, within the operating temperature range of -40°C to 200°C. All three parts share identical electrical specifications (4.7 Ohms, ±5%, 3W, wirewound, axial package) and regulatory compliance. Physical dimensions differ; verify PCB layout compatibility.

Q: What is the primary difference between the two YAGEO substitutes?

A: PNP300JR-73-4R7 and PNP3WVJR-73-4R7 differ in physical dimensions. PNP300JR-73-4R7 measures 0.181" diameter × 0.453" length, while PNP3WVJR-73-4R7 measures 0.217" diameter × 0.512" length. Electrical performance is identical; selection depends on available PCB space.

Q: Are there temperature limitations when substituting?

A: Yes. The CB3JB4R70 operates to 275°C, while both YAGEO substitutes are limited to 200°C. If your application requires operation above 200°C, the CB3JB4R70 must be used.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. CB3JB4R70, PNP300JR-73-4R7, and PNP3WVJR-73-4R7 are all ROHS3 Compliant and REACH Unaffected.

Q: What packaging formats are available?

A: CB3JB4R70 is supplied in Bulk packaging. PNP300JR-73-4R7 and PNP3WVJR-73-4R7 are supplied in Cut Tape (CT) packaging. Verify packaging compatibility with your procurement and assembly processes.
