Parameter Comparison

Engineering Selection Recommendations

Both the 23JR20 and 23JR20E are Active status components suitable for direct substitution in circuit applications requiring 200 mOhms ±5% 3W axial wirewound resistors. Selection between these parts should be based on compliance requirements and packaging needs:

The 23JR20E is RoHS Compliant with MSL 1 (Unlimited) rating, making it suitable for applications subject to RoHS directives and environments with no moisture sensitivity constraints. The 23JR20 is RoHS non-compliant and carries Not Applicable MSL designation, appropriate for legacy systems or applications without RoHS requirements. Both parts share identical electrical specifications, physical dimensions, and safety features, ensuring functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can the 23JR20E replace the 23JR20 in existing designs?

A: Yes. The 23JR20E is electrically and mechanically identical to the 23JR20. Both components have the same resistance value (200 mOhms), tolerance (±5%), power rating (3W), composition (Wirewound), axial package format, and physical dimensions (0.220" Dia x 0.516" L). Direct substitution is possible without circuit redesign.

Q: What is the primary difference between these two parts?

A: The primary differences are packaging format and compliance certifications. The 23JR20E is supplied in Bulk packaging and is RoHS Compliant with MSL 1 (Unlimited), while the 23JR20 uses standard packaging and is RoHS non-compliant with Not Applicable MSL. Electrical and mechanical specifications are identical.

Q: Are there any dimensional or footprint differences?

A: No. Both parts have identical physical dimensions of 0.220" Dia x 0.516" L (5.60mm x 13.10mm) and use the same axial through-hole package format. PCB layout and mounting considerations are identical.

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

A: The 23JR20E is RoHS Compliant and should be selected for applications requiring RoHS compliance. The 23JR20 is RoHS non-compliant and is not suitable for RoHS-regulated applications.

Q: Do these parts have different moisture sensitivity requirements?

A: The 23JR20E has MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. The 23JR20 has Not Applicable MSL designation. For applications with specific moisture handling requirements, the 23JR20E provides defined moisture sensitivity specifications.
