Ohmite 22J390 Equivalent & Substitute Parts

Part Overview

The Ohmite 22J390 is a 390 Ohm, 2W wirewound axial resistor with ±5% tolerance, designed for through-hole applications requiring flame retardant coating and safety features. This component is currently active in production. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when packaging requirements differ.

Substitute Part Grouping Explanation

Substitution for the Ohmite 22J390 is based on matching the following critical electrical and mechanical parameters:

• Resistance value: 390 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Wirewound
• Package: Axial through-hole
• Physical dimensions: 0.220" Dia x 0.421" L
• Temperature coefficient: ±30ppm/°C
• Features: Flame retardant coating and safety characteristics

The identified substitute part maintains identical electrical specifications and physical form factor, with the primary distinction being packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the 22J390 and 22J390E are active production components manufactured by Ohmite with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: the 22J390E is ROHS3 compliant, while the 22J390 is RoHS non-compliant. Both parts maintain REACH Unaffected status and share identical ECCN and HTSUS classifications.

Selection between these parts depends on regulatory requirements for the end application. Applications requiring RoHS3 compliance should specify the 22J390E. Applications without RoHS compliance requirements may use either part. Packaging configuration differs between the two: standard packaging for 22J390 and bulk packaging for 22J390E.

Frequently Asked Questions (FAQ)

Q: Are the 22J390 and 22J390E electrically identical?

A: Yes. Both parts have identical resistance (390 Ohms), tolerance (±5%), power rating (2W), temperature coefficient (±30ppm/°C), and composition (wirewound with flame retardant coating and safety features).

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 22J390E is ROHS3 compliant, while the 22J390 is RoHS non-compliant. Packaging also differs: 22J390 uses standard packaging, while 22J390E uses bulk packaging.

Q: Can I use 22J390E as a direct replacement for 22J390?

A: Yes, from an electrical and mechanical standpoint. However, verify that your application's regulatory requirements align with the RoHS compliance status of the selected part.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions of 0.220" Dia x 0.421" L (5.60mm x 10.70mm) and use the same axial through-hole package.

Q: What does the packaging difference mean?

A: The 22J390 comes in standard packaging, while the 22J390E is supplied in bulk packaging. This affects order quantities and handling but does not impact component performance or compatibility.
