Parameter Comparison

Engineering Selection Recommendations

Both the 23J2R0 and 23J2R0E are Active status components from Ohmite's Series 20 wirewound resistor line. The 23J2R0E offers RoHS compliance, which may be required for applications subject to RoHS regulations. The main part (23J2R0) is RoHS non-compliant. Selection between these parts should be based on regulatory requirements and compliance certifications applicable to the end application. All electrical and mechanical parameters are identical, ensuring direct functional substitution.

Frequently Asked Questions (FAQ)

Q: Can 23J2R0E be used as a direct replacement for 23J2R0?

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

Q: What is the significance of the packaging difference (standard vs. Bulk)?

A: Packaging format refers to the quantity and presentation method for procurement. Bulk packaging does not affect the component's electrical or mechanical performance. Selection depends on procurement quantity requirements.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both parts share identical temperature coefficients (±50ppm/°C) and feature specifications including flame retardant coating and safety features.

Q: Which part should be selected for RoHS-regulated applications?

A: The 23J2R0E is RoHS Compliant and should be selected for applications requiring RoHS compliance. The 23J2R0 is RoHS non-compliant.

Q: Do these parts have different moisture sensitivity levels?

A: The 23J2R0 lists MSL as Not Applicable, while 23J2R0E is rated MSL 1 (Unlimited). This reflects different classification methodologies and does not indicate functional differences for wirewound resistor applications.
