Key Parameters

Substitute Part Grouping Explanation

The WW5JT10R0 qualifies as a substitute based on the following matching electrical and mechanical parameters:

• Resistance value: 10 Ohms (identical)
• Tolerance: ±5% (identical)
• Composition: Wirewound (identical)
• Features: Moisture Resistant (identical)
• Temperature Coefficient: ±50ppm/°C (identical)
• Operating Temperature Range: -55°C ~ 350°C (identical)
• Package Type: Axial (identical)
• Terminations: 2 (identical)
• RoHS Status: ROHS3 Compliant (identical)

The primary difference is the power rating: WW5JT10R0 is rated at 5W versus the 3W rating of WW3JB10R0. This higher power rating allows the substitute to operate in applications requiring equal or lower power dissipation without performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Both WW3JB10R0 and WW5JT10R0 are active production components with ROHS3 compliance and REACH unaffected status. The WW5JT10R0 substitute provides identical electrical characteristics with a higher power dissipation capability. Selection between these parts depends on circuit power requirements and available inventory. The WW5JT10R0 is suitable for applications where the 3W rating of the original part may approach thermal limits or where design margin is required. Both components maintain identical temperature stability and operating range specifications.

Frequently Asked Questions (FAQ)

Q: Can WW5JT10R0 replace WW3JB10R0 in all applications?

A: Yes, the WW5JT10R0 can replace WW3JB10R0 in applications where the circuit power dissipation does not exceed 3W. The substitute's higher 5W rating provides additional thermal margin without affecting electrical performance at lower power levels.

Q: Are the physical dimensions compatible?

A: Both parts use axial package construction with two terminations. The WW5JT10R0 has larger physical dimensions (0.312" Dia x 0.875" L versus 0.187" Dia x 0.560" L). PCB layout and mechanical clearance must be verified before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes, both WW3JB10R0 and WW5JT10R0 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the difference in packaging format?

A: WW3JB10R0 is supplied in Bulk packaging, while WW5JT10R0 is supplied in Cut Tape (CT) format. This affects handling and assembly processes but does not impact electrical or mechanical performance.

Q: Are the temperature coefficients identical?

A: Yes, both parts have a temperature coefficient of ±50ppm/°C and operate across the same temperature range of -55°C to 350°C.
