Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 53J5R0E are identified based on strict equivalence of the following critical parameters:

• Resistance value: 5 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial with 2 terminations
• Temperature coefficient: ±50ppm/°C
• Environmental compliance: RoHS status

The Ohmite 43J5R0E qualifies as a direct substitute because it maintains identical electrical specifications and mechanical compatibility. Variations in packaging format (Box versus Bulk) and physical dimensions within the axial envelope do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 53J5R0E and 43J5R0E are active production components from Ohmite with full RoHS compliance certifications. The 53J5R0E (Series 50) is supplied in Box packaging with 804 units currently in inventory. The 43J5R0E (Ohmicone® 40 series) is supplied in Bulk packaging with 759 units in inventory.

Selection between these parts should be based on packaging requirements and inventory availability. The 43J5R0E exhibits a marginal length increase of 0.043" (1.10mm) compared to the 53J5R0E, which remains within standard axial resistor envelope tolerances and does not affect circuit board layout compatibility for typical applications. Both parts carry identical electrical performance characteristics and environmental compliance ratings.

Frequently Asked Questions (FAQ)

Q: Can the 43J5R0E replace the 53J5R0E in existing designs?

A: Yes. Both parts maintain identical resistance value (5 Ohms), tolerance (±5%), power rating (3W), temperature coefficient (±50ppm/°C), and axial package configuration. The minor dimensional difference (0.043" length increase) does not affect electrical performance or standard PCB layout compatibility.

Q: What is the difference between Box and Bulk packaging?

A: Box packaging (53J5R0E) and Bulk packaging (43J5R0E) refer to the quantity and presentation format for procurement. Both contain the same component with identical electrical specifications. Selection depends on order quantity requirements and inventory management practices.

Q: Are both parts RoHS compliant?

A: Yes. The 53J5R0E is RoHS Compliant, and the 43J5R0E is ROHS3 Compliant. Both meet current environmental regulatory requirements for electronic component manufacturing and use.

Q: What does the temperature coefficient specification mean?

A: The ±50ppm/°C temperature coefficient indicates the maximum change in resistance value per degree Celsius of temperature change. Both parts maintain this specification across their operating range, ensuring stable performance in varying thermal environments.

Q: Can these parts be used interchangeably in high-precision applications?

A: Yes, within the tolerance specification of ±5%. Both parts are wirewound resistors with identical tolerance ratings, making them suitable for applications requiring this level of precision. The temperature coefficient of ±50ppm/°C is maintained by both parts.
