CB2012T1R0MV Equivalent & Substitute Parts

Part Overview

The CB2012T1R0MV is a 1 µH unshielded drum core wirewound inductor manufactured by Taiyo Yuden, rated for 700 mA continuous current with a maximum DC resistance of 195 mOhm. The device is packaged in 0805 (2012 Metric) surface mount format and operates across the temperature range of -40°C to 105°C.

This part carries a "Not For New Designs" product status, indicating that Taiyo Yuden has discontinued active development and support for this component. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support existing production requirements for legacy systems or ongoing manufacturing commitments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CB2012T1R0MV is determined by strict equivalence across the following critical parameters:

Inductance Value: 1 µH nominal with ±20% tolerance Current Rating: 700 mA minimum continuous current capability Package Format: 0805 (2012 Metric) surface mount only Core Type: Ferrite drum core, wirewound, unshielded construction DC Resistance: Maximum 195 mOhm (substitute parts with lower DCR are acceptable) Operating Temperature: -40°C to 105°C minimum range Frequency Characteristics: Self-resonant frequency at 100 MHz; inductance test frequency at 7.96 MHz Compliance: ROHS3 compliant; MSL 1 (Unlimited)

The KEMET L0805C1R0MDWIT meets all critical substitution criteria. While the KEMET part carries an "Obsolete" product status and exhibits slightly lower DC resistance (190 mOhm versus 195 mOhm maximum), it maintains full electrical and mechanical compatibility with the CB2012T1R0MV across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Both the CB2012T1R0MV and L0805C1R0MDWIT carry legacy product status. The Taiyo Yuden part is marked "Not For New Designs," while the KEMET part is classified as "Obsolete." For applications requiring active manufacturer support and long-term availability, evaluation of current-generation 1 µH 0805 inductors from active product lines is recommended.

Substitution Viability: The L0805C1R0MDWIT is a direct electrical and mechanical substitute for the CB2012T1R0MV. Both parts satisfy identical inductance, current rating, package, and compliance requirements. The KEMET part's lower DC resistance (190 mOhm versus 195 mOhm maximum) represents an improvement in electrical performance and does not introduce compatibility issues.

Compliance Status: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard surface mount assembly processes and storage conditions.

Inventory and Availability: The CB2012T1R0MV maintains higher current inventory (4953 pieces) compared to the L0805C1R0MDWIT (1158 pieces). For immediate production requirements, the Taiyo Yuden part offers superior supply availability.

Frequently Asked Questions (FAQ)

Q: Can the L0805C1R0MDWIT replace the CB2012T1R0MV in existing designs?

A: Yes. The L0805C1R0MDWIT is a direct substitute. Both parts share identical inductance (1 µH), current rating (700 mA), package format (0805 / 2012 Metric), core type (ferrite drum core, unshielded), operating temperature range (-40°C to 105°C), and compliance certifications (ROHS3, MSL 1). The KEMET part's lower DC resistance (190 mOhm) is compatible with all circuit applications designed for the Taiyo Yuden part.

Q: What is the significance of the "Not For New Designs" status on the CB2012T1R0MV?

A: This designation indicates that Taiyo Yuden has discontinued active development and support for this component. Existing inventory remains available, but the manufacturer does not recommend this part for new product designs. For legacy system support or ongoing production of existing designs, the part remains functional and available.

Q: Are there dimensional differences between these two parts?

A: Yes. The CB2012T1R0MV measures 0.079" L × 0.049" W (2.00mm × 1.25mm) with a maximum seated height of 0.057" (1.45mm). The L0805C1R0MDWIT measures 0.083" L × 0.059" W (2.11mm × 1.50mm) with a maximum seated height of 0.041" (1.04mm). Both parts conform to the 0805 (2012 Metric) package specification. Verify PCB layout and component placement clearances before substitution.

Q: What is the difference in DC resistance between these parts?

A: The CB2012T1R0MV specifies a maximum DC resistance of 195 mOhm, while the L0805C1R0MDWIT specifies 190 mOhm. The KEMET part exhibits lower resistance, which reduces power dissipation and heat generation in the inductor. This represents an improvement and does not create compatibility issues.

Q: Are both parts suitable for high-frequency applications?

A: Both parts exhibit a self-resonant frequency of 100 MHz and are tested at 7.96 MHz. They are suitable for applications operating within these frequency parameters. Applications requiring operation above 100 MHz require evaluation of alternative inductor designs.

Q: What packaging formats are available for these parts?

A: The CB2012T1R0MV is supplied in Tape & Reel (TR) format. The L0805C1R0MDWIT is supplied in Cut Tape (CT) format. Both formats are compatible with standard surface mount assembly equipment. Verify packaging requirements for your production process.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the CB2012T1R0MV and L0805C1R0MDWIT are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both parts are suitable for applications requiring RoHS compliance and standard surface mount assembly and storage conditions.
