Parameter Comparison

Engineering Selection Recommendations

Both the 20J4K7 and 20J4K7E are Active status components manufactured by Ohmite with identical electrical and mechanical specifications. Selection between these parts is determined by compliance and packaging requirements:

The 20J4K7E offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulatory requirements. The 20J4K7 is RoHS non-compliant and appropriate for applications without RoHS compliance mandates. Both parts share identical REACH and ECCN classifications. Packaging differs between standard and bulk configurations; bulk packaging (20J4K7E) is applicable for high-volume procurement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 20J4K7E replace the 20J4K7 in all applications?

A: Yes, the 20J4K7E is electrically and mechanically equivalent to the 20J4K7. Both components share identical resistance value, tolerance, power rating, composition, package type, temperature coefficient, and physical dimensions. Selection depends on compliance requirements and packaging preferences.

Q: What is the difference between the 20J4K7 and 20J4K7E?

A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status. The 20J4K7E is ROHS3 compliant, while the 20J4K7 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are these parts suitable for high-temperature applications?

A: Both parts operate with a temperature coefficient of ±30ppm/°C. Operating temperature specifications are not provided in the component data. Verify operating temperature limits against application requirements.

Q: Does packaging format affect component performance?

A: No. Bulk packaging (20J4K7E) and standard packaging (20J4K7) do not affect electrical or mechanical performance. Packaging selection is based on procurement volume and handling requirements.

Q: Are both parts available in inventory?

A: The 20J4K7 has 791 pieces in stock. The 20J4K7E has 992 pieces in stock. Both are classified as New Original inventory.
