FIRCH-2 Equivalent & Substitute Parts Reference

Part Overview

The FIRCH-2 is a 3.05 µH unshielded drum core wirewound inductor manufactured by Triad Magnetics, designed for through-hole mounting applications. This component is rated for 9.7 A continuous current with a maximum DC resistance of 7.3 mOhm and operates across the temperature range of -40°C to 85°C. The part maintains Active product status with 1051 units currently in stock.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across inductance value, current rating, DC resistance, package type, and mounting configuration. Alternative models ensure design continuity when primary inventory becomes unavailable or when procurement requirements necessitate alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the FIRCH-2 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 3.05 µH (within ±15% tolerance specification)
• Current rating: 9.7 A minimum
• DC resistance: 7.3 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Equivalence Criteria:

• Package type: Radial, Vertical Cylinder (Open)
• Mounting type: Through Hole
• Physical dimensions: 16.00 mm L × 11.81 mm W
• Seated height: 26.67 mm maximum

Compliance Equivalence Criteria:

• RoHS3 compliance status
• REACH compliance status
• Product status: Active

The FIRCH-2-B meets all specified electrical, mechanical, and compliance parameters and is classified as a direct equivalent substitute.

Engineering Selection Recommendations

FIRCH-2-B as Direct Substitute:

The FIRCH-2-B is a direct equivalent substitute for the FIRCH-2. Both components are manufactured by Triad Magnetics within the same FIRCH series and maintain identical electrical specifications, mechanical dimensions, and compliance certifications.

Selection Basis:

• Both parts are Active status products from the same manufacturer
• Electrical parameters are identical: 3.05 µH inductance, 9.7 A current rating, 7.3 mOhm maximum DC resistance
• Mechanical compatibility is complete: identical package type, mounting configuration, and physical dimensions
• Regulatory compliance is equivalent: both are ROHS3 compliant and REACH unaffected
• Operating temperature range is identical: -40°C to 85°C
• Both components are currently in stock with sufficient inventory availability

The FIRCH-2-B may be selected as a substitute when the primary FIRCH-2 part number is unavailable or when procurement requirements necessitate alternative sourcing from the same manufacturer's product line.

Frequently Asked Questions (FAQ)

Q: What makes FIRCH-2-B a valid substitute for FIRCH-2?

A: The FIRCH-2-B meets all electrical and mechanical equivalence criteria. Both parts share identical inductance values (3.05 µH), current ratings (9.7 A), DC resistance specifications (7.3 mOhm max), core materials (ferrite), shielding configurations (unshielded), package types (radial, vertical cylinder open), mounting types (through hole), and physical dimensions (16.00 × 11.81 mm, 26.67 mm seated height). Both are manufactured by Triad Magnetics and maintain Active product status with identical compliance certifications.

Q: Are there any differences between FIRCH-2 and FIRCH-2-B?

A: The parts are electrically and mechanically identical. The only difference is current inventory levels: FIRCH-2 has 1051 units in stock, while FIRCH-2-B has 681 units in stock. Both are Active products from Triad Magnetics.

Q: Can FIRCH-2-B be used in existing designs specified for FIRCH-2?

A: Yes. The FIRCH-2-B is a direct equivalent substitute with identical electrical performance, mechanical fit, and compliance status. No design modifications are required for substitution.

Q: What are the critical parameters for substituting this inductor?

A: Substitution requires matching: inductance value (3.05 µH), current rating (9.7 A), DC resistance (7.3 mOhm max), core material (ferrite), shielding type (unshielded), package configuration (radial, vertical cylinder open), mounting type (through hole), and physical dimensions (16.00 × 11.81 × 26.67 mm).

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both FIRCH-2 and FIRCH-2-B are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the operating temperature range for these inductors?

A: Both the FIRCH-2 and FIRCH-2-B operate across the temperature range of -40°C to 85°C, with inductance measured at 10 kHz test frequency.
