AISC-1210HS-4R7K-T2 Equivalent & Substitute Parts

Part Overview

The AISC-1210HS-4R7K-T2 is a 4.7 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 550 mA continuous current with a maximum DC resistance of 950mOhm. This surface mount component in 1210 (3225 Metric) package is designed for applications requiring fixed inductance in compact form factors. The part is active in production and ROHS3 compliant. Substitute parts may be required due to inventory constraints, design optimization for improved performance parameters, or application-specific thermal and shielding requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the AISC-1210HS-4R7K-T2 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 4.7 µH (exact match required)
• Inductance tolerance: ±10% (matching tolerance class)
• Package / Case: 1210 (3225 Metric) (identical footprint and mounting)
• Mounting type: Surface Mount (same assembly method)

Secondary Compatibility Parameters:

• Current rating: Substitute must meet or exceed 550 mA
• DC resistance: Lower or equal DCR values are acceptable
• Operating temperature range: Must support application requirements
• RoHS and REACH compliance: Must maintain regulatory status

The substitute part SP1210R-472K meets all primary matching criteria with identical inductance, tolerance, and package specifications. Secondary parameters show improved current rating (633 mA vs 550 mA) and lower DC resistance (520mOhm vs 950mOhm), with extended operating temperature range (-55°C ~ 125°C vs -40°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications. The SP1210R-472K substitute provides enhanced electrical performance with 15% higher current rating and 45% lower DC resistance compared to the AISC-1210HS-4R7K-T2. The extended operating temperature range of the substitute (-55°C ~ 125°C) accommodates wider environmental conditions than the primary part (-40°C ~ 85°C). The primary design difference is shielding: the substitute features shielded construction versus the unshielded design of the original part. Selection between these parts depends on application-specific requirements for electromagnetic interference mitigation and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can SP1210R-472K be used as a direct replacement for AISC-1210HS-4R7K-T2?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical inductance (4.7 µH), tolerance (±10%), and package specifications (1210 / 3225 Metric). The substitute offers improved current handling and lower DC resistance. The primary design difference is shielding; applications sensitive to electromagnetic interference may benefit from the shielded substitute design.

Q: What are the key differences between these parts?

A: The main differences are: (1) Shielding—SP1210R-472K is shielded while AISC-1210HS-4R7K-T2 is unshielded; (2) Current rating—633 mA vs 550 mA; (3) DC resistance—520mOhm vs 950mOhm; (4) Operating temperature range—-55°C ~ 125°C vs -40°C ~ 85°C; (5) Manufacturer—API Delevan vs Abracon LLC.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Does the shielded design of SP1210R-472K affect PCB layout?

A: The physical dimensions are similar (3.20mm x 2.50mm vs 3.25mm x 2.42mm length and width), but the shielded part has greater height (2.57mm vs 1.30mm). PCB layout and component clearance must accommodate this height difference.

Q: Which part should be selected for high-temperature applications?

A: The SP1210R-472K substitute supports operating temperatures up to 125°C, compared to 85°C maximum for the AISC-1210HS-4R7K-T2. Applications requiring extended high-temperature operation should use the substitute part.
