Engineering Selection Recommendations

Direct Substitution (350 V Category): All direct substitutes maintain the original 350 V voltage specification. Selection among 350MXG150MEFCSN22X30, 381LX151M350H022, LGN2V151MELZ30, LQS2V151MELZ30, and 350VXH150MEFC22X30 is based on product status and compliance. All are active products with ROHS3 compliance. The 350VXH150MEFC22X30 offers extended lifetime (5000 Hrs @ 105°C) compared to the original 2000 Hrs specification.

Upgraded Substitution (400 V Category): The 400 V alternatives provide higher voltage margin while maintaining identical capacitance, tolerance, and physical dimensions. All 400 V options are active products with ROHS3 compliance. Selection depends on lifetime requirements: 400VXH150MEFC22X30 and 400VXH150MEFCSN22X30 provide 5000 Hrs @ 105°C, while 400MXG150MEFCSN22X30 and 381LX151M400H022 provide 3000 Hrs @ 105°C. The 400MXH150MEFCSN22X30 maintains 2000 Hrs @ 105°C equivalent to the original part.

All substitute parts are REACH Unaffected or REACH Affected with EAR99 ECCN classification, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V rated capacitor in place of the 350 V EET-HC2V151BA? A: Yes. A 400 V rated capacitor is electrically compatible in circuits designed for 350 V operation. The higher voltage rating provides additional safety margin without affecting circuit performance.

Q: Are all substitute parts mechanically identical to the original? A: All listed substitutes maintain identical lead spacing (0.394" / 10.00 mm), diameter (0.866" / 22.00 mm), and seated height (1.260" / 32.00 mm). They are all radial, can snap-in packages with through-hole mounting, ensuring direct PCB compatibility.

Q: What is the difference between direct substitutes and upgraded alternatives? A: Direct substitutes maintain the original 350 V rating. Upgraded alternatives provide 400 V rating, offering higher voltage margin. Both categories maintain all other electrical and mechanical specifications.

Q: Does the lifetime rating affect substitution compatibility? A: Lifetime rating does not affect electrical or mechanical compatibility. It indicates operational duration under specified conditions. Higher lifetime ratings (5000 Hrs vs. 2000 Hrs) provide extended service life in the same application.

Q: Are all substitute parts RoHS compliant? A: All active substitute parts listed are ROHS3 compliant. The original EET-HC2V151BA does not specify RoHS status.

Q: Which substitute offers the best overall performance? A: Selection depends on application requirements. The 400VXH150MEFCSN22X30 combines 400 V rating, 5000 Hrs @ 105°C lifetime, and highest inventory availability (273,982 pcs). For 350 V applications, the 350VXH150MEFC22X30 provides 5000 Hrs @ 105°C lifetime.
