Key Parameters

Substitute Part Grouping Explanation

The Ohmite 20J1R0E qualifies as a direct substitute based on the following critical parameters:

• Resistance value: 1 Ohms (identical)
• Tolerance: ±5% (identical)
• Power rating: 10W (identical)
• Composition: Wirewound (identical)
• Package type: Axial (identical)
• Physical dimensions: 0.394" Dia x 1.858" L (identical)
• Temperature coefficient: ±50ppm/°C (identical)
• Features: Flame retardant coating and safety characteristics (identical)
• Terminations: 2 (identical)

The primary distinction between these parts is packaging format and RoHS compliance status. The 20J1R0E is supplied in bulk packaging and meets ROHS3 compliance requirements, whereas the 20J1R0 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the 20J1R0 and 20J1R0E are electrically and mechanically equivalent. Selection between these parts should be based on:

• RoHS compliance requirements: Applications requiring ROHS3 compliance must use the 20J1R0E
• Packaging requirements: The 20J1R0E is available in bulk packaging, suitable for high-volume procurement
• Inventory availability: The 20J1R0E currently has higher inventory (2100 Pcs) compared to the 20J1R0 (840 Pcs)

Both parts maintain identical electrical performance, thermal characteristics, and physical form factor, ensuring direct interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 20J1R0E be used as a direct replacement for the 20J1R0?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, package type, and physical dimensions. The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between the standard and bulk packaging options?

A: The 20J1R0 uses standard packaging, while the 20J1R0E uses bulk packaging. Bulk packaging is typically used for high-volume orders and may offer cost advantages for large-quantity procurement.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status does not alter the electrical or thermal characteristics of the resistor. The 20J1R0E meets ROHS3 compliance requirements while maintaining identical performance specifications to the 20J1R0.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 20J1R0 and 20J1R0E have identical dimensions of 0.394" Dia x 1.858" L (10.00mm x 47.20mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What applications require these 10W axial wirewound resistors?

A: These components are used in applications requiring precise current limiting, load resistances, or power dissipation in through-hole configurations. The flame retardant coating and safety features make them suitable for industrial and safety-critical applications.
