Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R3J5K0 is determined by the following critical parameters:

• Resistance value: 5 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Radial (exact match required)
• Temperature coefficient: ±260ppm/°C (exact match required)
• Physical dimensions: 0.438" L x 0.313" W, height 0.469" max (exact match required)
• Termination count: 2 (exact match required)

The R3J5K0E qualifies as a parametric equivalent because it matches all electrical and mechanical specifications. Variations in packaging format (bulk vs. standard), RoHS compliance status, and moisture sensitivity level do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both R3J5K0 and R3J5K0E are active production components from Ohmite with identical electrical and mechanical characteristics. Selection between these parts should be based on the following factors:

R3J5K0: Select this part number when RoHS non-compliant components are acceptable for the application and standard packaging is required.

R3J5K0E: Select this part number when ROHS3 compliance is mandated by design or regulatory requirements. This variant is supplied in bulk packaging and carries MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Both parts are suitable for direct substitution in circuits requiring 5 kOhms, 3W, ±5% tolerance wirewound resistors with radial termination and flame retardant construction.

Frequently Asked Questions (FAQ)

Q: Can R3J5K0E replace R3J5K0 in existing designs? A: Yes. The R3J5K0E is electrically and mechanically identical to the R3J5K0. All circuit performance parameters remain unchanged. The primary difference is RoHS3 compliance status and packaging format.

Q: What is the significance of the RoHS compliance difference? A: RoHS3 compliance indicates the R3J5K0E meets current environmental and material restriction standards. The R3J5K0 is non-compliant with these standards. Selection depends on whether your application or supply chain requires RoHS certification.

Q: Are the physical dimensions identical between both parts? A: Yes. Both parts measure 0.438" L x 0.313" W (11.13mm x 7.95mm) with a maximum seated height of 0.469" (11.91mm). They are mechanically interchangeable in PCB layouts and mechanical assemblies.

Q: What does MSL rating mean for the R3J5K0E? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. The component can be stored and handled without desiccant packaging or environmental controls.

Q: Are both parts from the same manufacturer? A: Yes. Both R3J5K0 and R3J5K0E are manufactured by Ohmite and belong to the PC-58 series.

Q: What is the temperature coefficient specification used for? A: The ±260ppm/°C temperature coefficient defines the resistance value change per degree Celsius of temperature variation. This specification is identical for both parts and affects circuit performance in temperature-sensitive applications.
