Key Parameters

Substitute Part Grouping Explanation

The Ohmite 23J500E qualifies as a direct substitute based on identical electrical and mechanical parameters: 500 ohms resistance, ±5% tolerance, 3W power rating, wirewound composition, axial package configuration, and matching physical dimensions of 0.220" Dia x 0.516" L. Both parts belong to the Ohmite Series 20 and share identical temperature coefficient (±30ppm/°C), flame retardant coating, and safety features. The primary difference is packaging format: 23J500 is supplied in box packaging, while 23J500E is supplied in bulk packaging. Both maintain the same electrical performance and mechanical compatibility for circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

The 23J500E serves as a direct electrical and mechanical equivalent to the 23J500. Selection between these parts should be based on specific application requirements:

The 23J500E offers RoHS compliance, making it suitable for applications subject to RoHS regulatory requirements or customer specifications mandating compliant components. The 23J500 remains appropriate for applications without RoHS compliance mandates.

Both parts maintain identical electrical performance, physical dimensions, and thermal characteristics. Packaging format differences (box versus bulk) do not affect circuit functionality and should be selected based on procurement and inventory management needs.

Frequently Asked Questions (FAQ)

Q: Can 23J500E replace 23J500 in existing designs? A: Yes. The 23J500E is electrically and mechanically identical to the 23J500. Both provide 500 ohms ±5% at 3W with matching axial package dimensions and thermal characteristics. The substitute is suitable for direct board-level replacement.

Q: What is the difference between 23J500 and 23J500E? A: The primary differences are packaging format (box versus bulk) and RoHS compliance status. The 23J500E is RoHS compliant, while the 23J500 is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical between these parts? A: Yes. Both 23J500 and 23J500E measure 0.220" diameter by 0.516" length (5.60mm x 13.10mm), ensuring identical PCB footprint and mounting compatibility.

Q: Does RoHS compliance affect electrical performance? A: No. RoHS compliance status reflects material composition and manufacturing processes but does not alter the electrical specifications, resistance value, tolerance, power rating, or temperature coefficient of either part.

Q: Can these parts be used interchangeably in high-temperature applications? A: Yes. Both parts share identical temperature coefficient specifications (±30ppm/°C) and are suitable for equivalent thermal performance across the same operating range.
