SC1608C-2R2 Equivalent & Substitute Parts

Part Overview

The SC1608C-2R2 is a 2.2 µH shielded surface mount inductor manufactured by Signal Transformer, rated for 2.91 A continuous current with a maximum DC resistance of 50mOhm. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The shielded construction and specified electrical characteristics define the functional requirements for equivalent replacement options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC1608C-2R2 is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH with ±30% tolerance
• Current Rating: Substitute must support minimum 2.91 A continuous current
• DC Resistance: Maximum 50mOhm to maintain circuit performance
• Physical Footprint: Surface mount package with identical dimensions (6.60mm x 4.45mm) and height (2.92mm max)
• Operating Temperature: -40°C ~ 125°C range compatibility
• Compliance: ROHS3 and REACH compliance maintained

The SC1608F-2R2 meets the core inductance, tolerance, package, temperature, and compliance requirements. However, the substitute exhibits reduced current rating (2.4 A versus 2.91 A) and increased DC resistance (70mOhm versus 50mOhm), with a different shielding configuration (unshielded versus shielded).

Parameter Comparison

Engineering Selection Recommendations

The SC1608F-2R2 is an active product from the same manufacturer with identical physical footprint and inductance specifications. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Selection of SC1608F-2R2 as a substitute requires circuit-level evaluation of the following deviations:

• Current rating reduction from 2.91 A to 2.4 A impacts maximum allowable circuit current
• DC resistance increase from 50mOhm to 70mOhm introduces additional power dissipation
• Unshielded configuration differs from the original shielded design, affecting electromagnetic interference characteristics

These differences are material to circuit performance and must be assessed within the specific application context.

Frequently Asked Questions (FAQ)

Q: Can SC1608F-2R2 be used as a direct replacement for SC1608C-2R2?

A: Physical and electrical compatibility exists for the inductance value, tolerance, package dimensions, and temperature range. However, the reduced current rating (2.4 A vs. 2.91 A), increased DC resistance (70mOhm vs. 50mOhm), and unshielded construction represent functional differences that require application-specific evaluation.

Q: What is the impact of the shielding difference?

A: The SC1608C-2R2 features shielded construction, while the SC1608F-2R2 is unshielded. Shielding reduces electromagnetic radiation and susceptibility to external fields. Applications sensitive to EMI or operating in electromagnetically noisy environments may require the shielded variant.

Q: How does the DC resistance increase affect circuit performance?

A: The 20mOhm increase in maximum DC resistance (from 50mOhm to 70mOhm) results in higher resistive losses. In circuits carrying the full 2.91 A rating, this produces additional heat dissipation. The actual impact depends on circuit current levels and thermal design margins.

Q: Are both parts physically interchangeable on the PCB?

A: Yes. Both components share identical surface mount package dimensions (6.60mm x 4.45mm) and maximum seated height (2.92mm), allowing direct PCB footprint compatibility.

Q: What compliance certifications apply to both parts?

A: Both SC1608C-2R2 and SC1608F-2R2 maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to these requirements.
