Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCIHP0730-8R2M is determined by strict equivalence across the following critical parameters:

• Inductance value: 8.2 µH with ±20% tolerance
• Current rating: 4 A minimum
• Saturation current (Isat): 6 A minimum
• DC resistance: 68 mOhm maximum
• Shielding: Shielded construction required
• Physical dimensions: 0.287" L x 0.268" W (7.30mm x 6.80mm) with maximum height of 0.118" (3.00mm)
• Mounting: Surface mount, nonstandard package
• Operating temperature range: -55°C ~ 125°C
• Test frequency: 200 kHz
• Compliance: RoHS3 compliant, REACH unaffected

The ASPI-7318-8R2M-T from Abracon LLC meets all specified electrical and mechanical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the SCIHP0730-8R2M and ASPI-7318-8R2M-T maintain Active product status and are fully compliant with RoHS3 and REACH requirements. Selection between these parts should be based on availability, lead time, and supplier preference, as all electrical and mechanical specifications are equivalent. The ASPI-7318-8R2M-T utilizes a ferrite drum core construction, while the SCIHP0730-8R2M core material is not specified; however, this distinction does not affect substitution eligibility given the matched performance parameters across all critical operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-7318-8R2M-T replace the SCIHP0730-8R2M in existing designs?

A: Yes. Both parts meet identical electrical specifications (8.2 µH inductance, 4 A current rating, 68 mOhm DCR, 6 A saturation current) and physical dimensions (7.30mm x 6.80mm x 3.00mm max height). Both are shielded, surface mount components with equivalent operating temperature ranges and compliance certifications.

Q: Are there differences in core construction between these parts?

A: The ASPI-7318-8R2M-T specifies ferrite drum core construction, while the SCIHP0730-8R2M core material is not specified in the provided data. Both achieve the same inductance value and DC resistance within the specified tolerance at the 200 kHz test frequency.

Q: Do both parts have the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging and use nonstandard package cases with identical physical dimensions.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SCIHP0730-8R2M and ASPI-7318-8R2M-T are RoHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status.

Q: What is the inductance tolerance for these parts?

A: Both parts have an inductance tolerance of ±20%, meaning the actual inductance value will fall between 6.56 µH and 9.84 µH.
