Parameter Comparison

Engineering Selection Recommendations

Both the 22J30RE and 22J30R are Active status components from Ohmite's Series 20 wirewound resistor line. The primary distinction between these parts is regulatory compliance: the 22J30RE is ROHS3 Compliant, while the 22J30R is RoHS non-compliant. Selection between these parts should be based on application requirements regarding RoHS compliance mandates. Both parts maintain identical electrical specifications, physical dimensions, and safety features. The 22J30RE is recommended for applications requiring RoHS3 compliance certification. The 22J30R remains suitable for applications without RoHS compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 22J30R be used as a direct replacement for the 22J30RE?

A: The 22J30R is electrically and mechanically equivalent to the 22J30RE. Both components share identical resistance, tolerance, power rating, composition, package type, temperature coefficient, and physical dimensions. The primary difference is RoHS compliance status. Selection depends on whether your application requires ROHS3 Compliant certification.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: resistance value (30 Ohms), tolerance (±5%), power rating (2W), composition (Wirewound), package type (Axial), temperature coefficient (±30ppm/°C), physical dimensions (0.220" Dia x 0.421" L), and termination count (2). All these parameters must align for functional equivalence.

Q: Are there any physical installation differences between these parts?

A: No. Both the 22J30RE and 22J30R share identical axial package dimensions of 0.220" Dia x 0.421" L (5.60mm x 10.70mm) with 2 terminations. They are mechanically interchangeable in through-hole PCB applications.

Q: What is the significance of the RoHS compliance difference?

A: The 22J30RE is ROHS3 Compliant, meeting Restriction of Hazardous Substances regulations. The 22J30R is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS certification must use the 22J30RE.

Q: Do both parts have the same temperature performance characteristics?

A: Yes. Both the 22J30RE and 22J30R have identical temperature coefficients of ±30ppm/°C, ensuring equivalent thermal stability across operating conditions.
