Engineering Selection Recommendations

SS26V-R250061 (Same Footprint, Higher Inductance) Select this part when higher inductance filtering is required within the identical physical footprint. Maintains 2.5A current rating and 150 mOhm DCR. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are equivalent to the main part.

SS28V-25045-CH (Similar Inductance, Larger Footprint) Select this part when PCB space permits a larger footprint (30.00 x 22.00 mm). Provides inductance of 4.5 mH, closely matching the main part specification. Current rating remains 2.5A. DCR increases to 160 mOhm. Suitable for applications where footprint constraints are relaxed.

SS28V-R25080-CH (Higher Inductance, Larger Footprint) Select this part for applications requiring 8 mH inductance with 2.5A current rating. Larger footprint (30.00 x 22.00 mm) accommodates the higher inductance value. DCR is 160 mOhm. All compliance certifications match the main part.

SS28H-R25080-CH (Higher Inductance, Square Footprint) Select this part when 8 mH inductance is required and a square footprint (30.00 x 30.00 mm) is acceptable. Current rating is 2.5A with 160 mOhm DCR. Height is reduced to 24.50 mm compared to other options. All compliance certifications are equivalent.

SS30V-300054 (Higher Current Rating, Optimized DCR) Select this part when applications require 3A current capacity with lower DC resistance (120 mOhm). Inductance is 5.4 mH. Footprint is 31.00 x 22.50 mm. All compliance certifications match the main part. Suitable for higher power applications.

SS30V-R300071 (Higher Current Rating, Higher Inductance) Select this part for applications requiring both 3A current capacity and 7.1 mH inductance. DC resistance is optimized at 120 mOhm. Footprint is 31.00 x 22.50 mm. All compliance certifications are equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can SS26V-R250061 be used as a direct replacement for SS26V-250046? A: Yes, within the same physical footprint. The primary difference is inductance: 6.1 mH versus 4.6 mH. Both parts maintain 2.5A current rating, 150 mOhm DCR, and identical compliance certifications. Selection depends on whether the higher inductance value is compatible with circuit requirements.

Q: What is the difference between SS28V and SS30V series substitutes? A: SS28V parts maintain the 2.5A current rating of the main part but offer larger footprints and variable inductance options (4.5 mH to 8 mH). SS30V parts increase the current rating to 3A and reduce DCR to 120 mOhm, suitable for higher power applications. Both series use identical 250V AC voltage rating and operating temperature range.

Q: Does footprint size affect electrical performance? A: Footprint size correlates with inductance value and DCR characteristics. Larger footprints (SS28V, SS30V) accommodate higher inductance values or lower DCR. However, electrical performance is determined by the specific inductance, current rating, and DCR values, not footprint size alone.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, matching the main part SS26V-250046.

Q: Which substitute provides the lowest DC resistance? A: SS30V-300054 and SS30V-R300071 both provide 120 mOhm DCR, the lowest among all listed parts. This is achieved through the SS30V series design, which also increases current rating to 3A.

Q: Can SS26V-250046 be replaced with an SS30V part in a 2.5A circuit? A: Yes. SS30V parts are rated for 3A, which exceeds the 2.5A requirement. The higher current rating provides design margin. However, verify that the inductance value (5.4 mH or 7.1 mH for SS30V options) is compatible with circuit specifications.

Q: What is the physical constraint when selecting between SS28H-R25080-CH and SS28V-R25080-CH? A: Both parts provide 8 mH inductance and 2.5A rating. SS28H-R25080-CH has a square footprint (30.00 x 30.00 mm) with reduced height (24.50 mm). SS28V-R25080-CH has a rectangular footprint (30.00 x 22.00 mm) with increased height (35.50 mm). Selection depends on available PCB space orientation and clearance requirements.

Q: Are operating temperature ranges identical across all substitute parts? A: Yes. All substitute parts operate within -25°C to 120°C, matching the main part SS26V-250046.
