MLF1608A2R2M Equivalent & Substitute Parts

Part Overview

The MLF1608A2R2M is a 2.2 µH shielded multilayer inductor manufactured by TDK Corporation, designed for surface mount applications in the 0603 (1608 Metric) package. This ferrite-core inductor operates at 30 mA maximum current with 1 Ohm maximum DC resistance and is rated for -40°C to 85°C operating temperature. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies requiring compact inductance solutions.

Equivalent parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for functionally compatible alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the MLF1608A2R2M is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH (exact match required)
• Package / Case: Must be 0603 (1608 Metric) for mechanical and electrical compatibility
• Shielding Type: Must be Shielded to maintain electromagnetic isolation
• Core Material: Must be Ferrite for consistent performance characteristics
• Mounting Type: Must be Surface Mount for PCB assembly compatibility
• Current Rating: Must meet or exceed 30 mA minimum requirement
• DC Resistance: Must not exceed 1 Ohm maximum specification
• Compliance: Must maintain ROHS3 compliance for regulatory alignment

The CS160808-2R2K from Bourns Inc. meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CS160808-2R2K is a direct functional equivalent to the MLF1608A2R2M. Both parts are Active status products with ROHS3 compliance and REACH Unaffected designation, ensuring regulatory alignment for current and future applications.

The Bourns CS160808-2R2K offers performance advantages including tighter inductance tolerance (±10% versus ±20%), higher current rating (50 mA versus 30 mA), lower DC resistance (900 mOhm versus 1 Ohm maximum), and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C). These characteristics make the CS160808-2R2K suitable for applications requiring enhanced thermal performance or higher current capacity within the same physical footprint.

Both parts maintain identical mechanical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm) and maximum seated height (0.037", 0.95mm), ensuring direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the CS160808-2R2K replace the MLF1608A2R2M in existing designs?

A: Yes. Both parts share identical inductance values (2.2 µH), package specifications (0603/1608 Metric), shielding type (Shielded), and core material (Ferrite). The CS160808-2R2K meets or exceeds all electrical specifications of the MLF1608A2R2M, including current rating and DC resistance limits.

Q: What are the key differences between these two parts?

A: The CS160808-2R2K provides tighter inductance tolerance (±10% versus ±20%), higher current capacity (50 mA versus 30 mA), lower DC resistance (900 mOhm versus 1 Ohm), higher Q factor (50 versus 35 at 10MHz), and wider operating temperature range (-55°C to 125°C versus -40°C to 85°C). The MLF1608A2R2M has a higher self-resonant frequency (80 MHz versus 45 MHz).

Q: Are there any package or footprint compatibility concerns?

A: No. Both parts use the 0603 (1608 Metric) package with identical dimensions and mounting specifications. No PCB layout modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MLF1608A2R2M and CS160808-2R2K are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. The CS160808-2R2K is suitable for applications requiring higher current capacity, lower DC resistance, or extended temperature operation. The MLF1608A2R2M remains appropriate for standard applications within its specified operating parameters.
