Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0704S-102M-T is determined by strict equivalence across the following critical parameters:

Inductance value must be 1 mH with ±20% tolerance. Current rating must support minimum 180 mA continuous operation. DC resistance must not exceed 6 Ohm maximum specification. Core material must be ferrite with shielding configuration. Package dimensions must match 7.30mm x 7.30mm footprint with maximum seated height of 4.50mm. Mounting type must be surface mount. RoHS3 compliance and MSL 1 rating are required for regulatory and environmental compatibility.

The CDRH74NP-102MC-B from Sumida America Components Inc. meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ASPI-0704S-102M-T and CDRH74NP-102MC-B are Active status components with ROHS3 compliance and MSL 1 ratings, confirming regulatory and environmental suitability for equivalent applications. The primary distinction is the operating temperature maximum: the Abracon part supports -40°C to 125°C, while the Sumida part supports -40°C to 100°C. Selection between these parts should be based on application temperature requirements. For applications operating above 100°C, the ASPI-0704S-102M-T is the appropriate choice. For applications within the -40°C to 100°C range, either part is electrically and mechanically compatible. Inventory availability and procurement lead times may also influence selection, with Sumida currently showing higher stock levels at 57190 pieces.

Frequently Asked Questions (FAQ)

Q: Can CDRH74NP-102MC-B replace ASPI-0704S-102M-T in all applications?

A: Substitution is valid for applications operating within -40°C to 100°C. Applications requiring operation above 100°C must use the ASPI-0704S-102M-T due to its extended temperature rating to 125°C.

Q: Are the physical packages identical?

A: Yes. Both parts share identical footprint dimensions of 7.30mm x 7.30mm with maximum seated height of 4.50mm, ensuring direct PCB layout compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting equivalent regulatory and environmental standards.

Q: What is the difference in DC resistance specification?

A: The Abracon part specifies 6 Ohm nominal, while the Sumida part specifies 6 Ohm maximum. Both meet the 6 Ohm requirement for circuit design purposes.

Q: Are there differences in inductance test frequency?

A: Yes. The Abracon part is tested at 100 kHz, while the Sumida part is tested at 1 kHz. Both maintain 1 mH inductance within ±20% tolerance at their respective test frequencies.

Q: Which part should be selected for new designs?

A: Selection depends on application temperature range. For designs requiring maximum temperature flexibility, specify ASPI-0704S-102M-T. For designs within standard industrial temperature ranges, either part is acceptable based on availability and lead time.
