CB3JB10R0 Equivalent & Substitute Parts

Part Overview

The CB3JB10R0 is a 10 Ohm ±5% 3W axial wirewound resistor manufactured by Stackpole Electronics Inc. This through-hole component features flame-proof and moisture-resistant construction with safety certification, designed for applications requiring reliable power dissipation in harsh environments. The part maintains Active product status with 889 units in current inventory. Substitute parts become necessary when primary inventory is depleted, when alternative sourcing is required for supply chain continuity, or when equivalent electrical and mechanical specifications can satisfy application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the CB3JB10R0 is determined by strict equivalence across the following critical parameters:

Resistance value: 10 Ohms (exact match required)
Tolerance: ±5% (exact match required)
Power rating: 3W (exact match required)
Composition: Wirewound (exact match required)
Package: Axial through-hole (exact match required)
Regulatory compliance: ROHS3 Compliant and REACH Unaffected (minimum requirement)

The substitute parts PNP300JR-73-10R and PNP3WVJR-73-10R, both manufactured by YAGEO, satisfy all electrical parameter requirements. Both parts are wirewound axial resistors rated at 10 Ohms ±5% 3W with ROHS3 compliance and REACH Unaffected status. Physical dimensions vary within acceptable axial package tolerances. Operating temperature ranges differ but do not preclude substitution in applications within the overlapping -40°C ~ 200°C window.

Engineering Selection Recommendations

Both YAGEO substitute parts maintain Active product status and full regulatory compliance (ROHS3 and REACH Unaffected), establishing baseline qualification for direct substitution. Selection between PNP300JR-73-10R and PNP3WVJR-73-10R depends on application-specific thermal requirements and physical space constraints.

For applications operating within -40°C ~ 200°C, both substitutes are electrically and mechanically equivalent to the CB3JB10R0. Applications requiring operation below -40°C or above 200°C must retain the CB3JB10R0 due to its extended -55°C ~ 275°C operating range.

Physical dimensions differ: PNP300JR-73-10R measures 0.181" Dia x 0.453" L (4.60mm x 11.50mm), while PNP3WVJR-73-10R measures 0.217" Dia x 0.512" L (5.50mm x 13.00mm), compared to the CB3JB10R0 at 0.315" Square x 0.866" L (8.00mm x 22.00mm). PCB layout and mechanical clearance requirements determine which substitute is appropriate.

Frequently Asked Questions (FAQ)

Q: Can PNP300JR-73-10R and PNP3WVJR-73-10R be used interchangeably with CB3JB10R0?

A: Both YAGEO parts satisfy the core electrical specifications (10 Ohms ±5% 3W wirewound axial). Interchangeability is confirmed for applications operating within the overlapping -40°C ~ 200°C temperature window. Applications requiring extended temperature operation must use CB3JB10R0.

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

A: Both parts are electrically identical. The difference is physical size: PNP300JR-73-10R is smaller (4.60mm x 11.50mm) while PNP3WVJR-73-10R is larger (5.50mm x 13.00mm). Selection depends on available PCB space and mechanical constraints.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. CB3JB10R0, PNP300JR-73-10R, and PNP3WVJR-73-10R are all ROHS3 Compliant and REACH Unaffected.

Q: What packaging formats are available?

A: CB3JB10R0 is supplied in Bulk packaging. Both YAGEO substitutes (PNP300JR-73-10R and PNP3WVJR-73-10R) are supplied in Cut Tape (CT) format. Packaging format does not affect electrical or mechanical performance.

Q: Which substitute has better inventory availability?

A: PNP300JR-73-10R has the highest current inventory at 53993 units, followed by PNP3WVJR-73-10R at 1990 units, compared to CB3JB10R0 at 889 units.
