CIG10F2R2MNC Equivalent & Substitute Parts

Part Overview

The CIG10F2R2MNC is a 2.2 µH shielded multilayer inductor manufactured by Samsung Electro-Mechanics, rated for 500 mA with 450mOhm DC resistance in a 0603 (1608 Metric) surface mount package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across inductance value, current rating, shielding characteristics, and package dimensions while meeting modern compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CIG10F2R2MNC is determined by the following mandatory parameters:

Core Compatibility Criteria:

• Inductance value: 2.2 µH (±20% tolerance)
• Current rating: minimum 500 mA
• Shielding: Shielded configuration required
• Package: 0603 (1608 Metric) surface mount only
• Type: Multilayer construction
• DC Resistance: acceptable range 325mOhm to 475mOhm

Compliance Requirements:

• RoHS3 compliance mandatory
• MSL rating 1 (Unlimited) preferred
• Operating temperature range must encompass -40°C minimum

All three substitute parts meet these criteria. The KLZ1608AHR2R2WTD25 offers improved DC resistance (325mOhm) with extended temperature range and AEC-Q200 rating. The LQM18PN2R2MFHD and LQM18PZ2R2MFHD provide higher current ratings (700 mA) with comparable or lower DC resistance, with LQM18PZ2R2MFHD offering AEC-Q200 qualification and extended temperature range (-55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

KLZ1608AHR2R2WTD25 (TDK Corporation)

This substitute provides direct current rating equivalence (500 mA) with superior DC resistance performance (325mOhm versus 450mOhm). The extended operating temperature range (-55°C ~ 150°C) accommodates broader environmental specifications. AEC-Q200 qualification indicates automotive-grade reliability. Soft termination feature provides enhanced mechanical robustness. Suitable for applications requiring matched current specifications with improved efficiency characteristics.

LQM18PN2R2MFHD (Murata Electronics)

This substitute offers elevated current rating (700 mA) providing design margin above the original 500 mA specification. DC resistance remains within acceptable range (475mOhm maximum). Active product status with substantial inventory availability (16,000 pcs) ensures procurement continuity. Operating temperature range (-40°C ~ 85°C) covers the original specification minimum. Appropriate for applications where current headroom is beneficial and upper temperature limit of 85°C is acceptable.

LQM18PZ2R2MFHD (Murata Electronics)

This substitute combines elevated current rating (700 mA) with optimized DC resistance (470mOhm maximum) and extended operating temperature range (-55°C ~ 125°C). AEC-Q200 qualification provides automotive-grade assurance. Largest inventory availability (299,387 pcs) ensures supply security. Recommended for applications requiring extended temperature performance, automotive compliance, and maximum design flexibility within the 2.2 µH 0603 package category.

Frequently Asked Questions (FAQ)

Q: Can LQM18PN2R2MFHD be used in place of CIG10F2R2MNC if the operating temperature never exceeds 85°C?

A: Yes. The LQM18PN2R2MFHD meets all mandatory electrical parameters (2.2 µH inductance, 500+ mA current capability, shielded multilayer construction, 0603 package). The 85°C upper temperature limit is acceptable provided the application design confirms operation within this boundary. DC resistance (475mOhm maximum) is within acceptable tolerance relative to the original 450mOhm specification.

Q: What is the significance of the DC resistance difference between KLZ1608AHR2R2WTD25 (325mOhm) and the original CIG10F2R2MNC (450mOhm)?

A: Lower DC resistance reduces resistive losses in the inductor, resulting in improved efficiency and reduced heat generation. The 325mOhm value represents approximately 28% lower resistance than the original 450mOhm specification. This improvement is beneficial in power conversion applications where thermal management and efficiency are critical design factors.

Q: Are all three substitute parts pin-compatible with the CIG10F2R2MNC?

A: Yes. All substitute parts use identical 0603 (1608 Metric) surface mount package dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm). PCB footprint compatibility is maintained across all substitutes. Height variations (0.030" to 0.037" seated maximum) fall within standard 0603 package tolerances and do not affect assembly compatibility.

Q: Which substitute part is recommended for automotive applications?

A: Both KLZ1608AHR2R2WTD25 and LQM18PZ2R2MFHD carry AEC-Q200 qualification, indicating compliance with automotive reliability standards. LQM18PZ2R2MFHD is preferred for automotive designs due to extended temperature range (-55°C ~ 125°C), superior inventory availability, and optimized DC resistance specification.

Q: What is the practical difference between ±20% inductance tolerance across all parts?

A: All parts share identical ±20% inductance tolerance, meaning the 2.2 µH specification can vary between 1.76 µH and 2.64 µH. This tolerance is consistent across the original and all substitute parts, requiring no circuit design modifications. Applications must accommodate this tolerance range regardless of part selection.

Q: Can LQM18PZ2R2MFHD replace CIG10F2R2MNC in a design operating at -55°C?

A: Yes. The LQM18PZ2R2MFHD operating temperature range (-55°C ~ 125°C) encompasses -55°C operation. The original CIG10F2R2MNC specification (-40°C ~ 125°C) does not support -55°C operation. If the application requires -55°C capability, LQM18PZ2R2MFHD or KLZ1608AHR2R2WTD25 are the appropriate selections.
