Parameter Comparison

Engineering Selection Recommendations

90J250 Selection Criteria:

• Applications without RoHS3 compliance requirements
• Designs where standard packaging is specified
• Existing inventory availability (1011 units in stock)

90J250E Selection Criteria:

• Applications requiring ROHS3 compliance
• Designs requiring bulk packaging configuration
• Moisture-sensitive environments where MSL 1 (Unlimited) rating is beneficial
• New designs where regulatory compliance is mandatory

Both parts maintain identical electrical performance and mechanical compatibility. Selection between 90J250 and 90J250E depends on compliance requirements and packaging specifications rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can 90J250E replace 90J250 in existing designs? A: Yes. The 90J250E is electrically and mechanically identical to the 90J250. The primary differences are RoHS3 compliance and packaging configuration. Designs currently using 90J250 can transition to 90J250E without circuit modifications.

Q: What is the difference between standard and bulk packaging? A: Standard packaging (90J250) and bulk packaging (90J250E) refer to the quantity and presentation method for shipment. Both contain identical components with the same electrical and mechanical specifications. Bulk packaging typically offers cost advantages for high-volume applications.

Q: Does RoHS3 compliance affect component performance? A: No. RoHS3 compliance (90J250E) indicates the component meets environmental and material restrictions but does not alter electrical performance, power rating, or temperature characteristics. Both parts deliver identical 11W power dissipation at 250 Ohms ±5%.

Q: Are the physical dimensions identical between 90J250 and 90J250E? A: Yes. Both parts measure 0.343" Dia x 1.811" L (8.70mm x 46.00mm) and use identical axial package configuration with 2 terminations. PCB layout and mounting requirements are identical.

Q: What does MSL 1 (Unlimited) mean for 90J250E? A: MSL 1 (Unlimited) indicates the component has unlimited shelf life without moisture baking requirements. This is beneficial for long-term storage and applications in humid environments.

Q: Which part should be selected for new designs? A: For new designs, 90J250E is recommended when regulatory compliance is a consideration. Both parts are Active status with stable inventory. Selection should align with project compliance requirements and packaging specifications.
