R3J1K0 Equivalent & Substitute Parts

Part Overview

The R3J1K0 is a 1 kOhms ±5% 3W through-hole resistor manufactured by Ohmite from the PC-58 series. This wirewound resistor features flame retardant coating and safety construction, designed for axial lead configuration. The part is currently active in production with 912 pieces in stock. Substitute parts become necessary when axial package availability is limited, when bulk packaging is preferred for manufacturing operations, or when alternative lead configurations better suit specific circuit board layouts.

Key Parameters

Substitute Part Grouping Explanation

The R3J1K0E qualifies as a parametric equivalent to the R3J1K0 based on the following criteria:

• Identical resistance value: 1 kOhms
• Identical tolerance: ±5%
• Identical power rating: 3W
• Identical composition: Wirewound
• Identical features: Flame Retardant Coating, Safety
• Identical temperature coefficient: ±260ppm/°C
• Identical series designation: PC-58
• Identical product status: Active
• Same number of terminations: 2

The primary difference between these parts is the package configuration: R3J1K0 uses axial lead termination, while R3J1K0E uses radial lead termination. Both are through-hole components suitable for PCB mounting. The R3J1K0E is supplied in bulk packaging versus the box packaging of the R3J1K0.

Parameter Comparison

Engineering Selection Recommendations

Both R3J1K0 and R3J1K0E are active production parts from the same manufacturer and series. Selection between these parts should be based on circuit board layout requirements and lead configuration compatibility.

The R3J1K0E offers ROHS3 compliance, which may be required for applications subject to RoHS3 regulations. The R3J1K0 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Lead configuration determines suitability: axial leads (R3J1K0) are appropriate for through-hole designs with linear PCB routing, while radial leads (R3J1K0E) are suitable for designs requiring compact vertical mounting or specific hole spacing patterns.

Frequently Asked Questions (FAQ)

Q: Can R3J1K0E replace R3J1K0 in any application?

A: R3J1K0E can replace R3J1K0 in applications where the radial lead configuration is compatible with the PCB layout. The electrical characteristics are identical. Physical lead configuration and mounting hole spacing must be verified before substitution.

Q: What is the difference between axial and radial lead configurations?

A: Axial leads extend from opposite ends of the resistor body and are typically used in linear PCB routing. Radial leads extend from the same end of the resistor body and are used for compact vertical mounting. PCB hole spacing and layout design determine which configuration is appropriate.

Q: Does RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical characteristics. RoHS3 compliance is a regulatory requirement for specific markets and applications.

Q: Are both parts available in sufficient quantity?

A: Yes. R3J1K0 has 912 pieces in stock, and R3J1K0E has 1067 pieces in stock. Both are active production parts.

Q: What packaging differences exist between these parts?

A: R3J1K0 is supplied in box packaging, while R3J1K0E is supplied in bulk packaging. Packaging selection depends on manufacturing workflow and inventory management requirements.
