Parameter Comparison

Engineering Selection Recommendations

Both the 90J400 and 90J400E are Active status components from Ohmite's Series 90 wirewound resistor line. The 90J400E offers ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, compared to the 90J400 which is RoHS non-compliant. Selection between these parts should be based on regulatory requirements and supply chain availability. Both parts are electrically and mechanically identical and provide equivalent performance in circuit applications requiring 400 Ohm, 11W axial wirewound resistors with flame retardant safety features.

Frequently Asked Questions (FAQ)

Q: Can the 90J400E directly replace the 90J400 in existing designs?

A: Yes. The 90J400E is a direct functional equivalent with identical electrical specifications (400 Ohms, ±5%, 11W), composition (wirewound), and physical dimensions (0.343" Dia x 1.811" L). Both components feature flame retardant coating and safety characteristics. The parts are interchangeable at the circuit level.

Q: What is the difference between the 90J400 and 90J400E?

A: The primary differences are packaging format (standard vs. Bulk) and regulatory compliance. The 90J400E is ROHS3 compliant with MSL Level 1 rating, while the 90J400 is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any dimensional or mounting differences?

A: No. Both parts share identical physical dimensions of 0.343" Dia x 1.811" L (8.70mm x 46.00mm) and use the same axial package configuration with 2 terminations. Board layout and mounting procedures remain unchanged.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and compliance requirements. For applications requiring RoHS compliance, the 90J400E is the appropriate choice. Both parts are Active status and suitable for new designs within their specified electrical and thermal operating parameters.

Q: Are the temperature coefficients identical?

A: Yes. Both the 90J400 and 90J400E have a temperature coefficient of ±30ppm/°C, ensuring equivalent thermal performance across operating conditions.
