MMAST105SB7682MFNA01 Equivalent & Substitute Parts

Part Overview

The MMAST105SB7682MFNA01 is a 6800 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V with X7R temperature coefficient in 0402 (1005 Metric) surface mount package. This component is classified as Active product status and is suitable for medical and non-critical applications. The part is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, inventory depletion, or when design requirements permit alternative qualified sources meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMAST105SB7682MFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 6800 pF
• Tolerance: ±20%
• Voltage rating: 25V
• Temperature coefficient: X7R

Mechanical Parameters:

• Package type: 0402 (1005 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Maximum thickness: 0.022" (0.55mm)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C ~ 125°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance status

The substitute part C1005X7R1E682M manufactured by TDK Corporation meets all specified electrical and mechanical parameters. Substitution is valid when all parameters listed above are identical between the main part and the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The MMAST105SB7682MFNA01 (Taiyo Yuden) is the preferred selection when available. This part carries Active product status, indicating ongoing manufacturer support and availability. Current inventory of 865 pieces supports immediate procurement requirements.

Substitute Part Selection: The C1005X7R1E682M (TDK Corporation) is a parametric equivalent meeting all electrical and mechanical specifications. However, this part is classified as Obsolete product status. Selection of this substitute is appropriate only when the primary part is unavailable and design requirements permit use of an obsolete component. Current inventory of 974 pieces is available.

Compliance Considerations: The primary part MMAST105SB7682MFNA01 is explicitly RoHS3 compliant. The substitute part C1005X7R1E682M does not have RoHS status specified in the provided data. Compliance verification with the substitute part is necessary for applications requiring RoHS certification.

Packaging Considerations: The primary part is supplied in Tape & Reel (TR) packaging. The substitute part is supplied in Cut Tape (CT) & Digi-Reel® packaging. Packaging format differences may affect handling, storage, and assembly line integration.

Frequently Asked Questions (FAQ)

Q: Can C1005X7R1E682M be used as a direct replacement for MMAST105SB7682MFNA01?

A: C1005X7R1E682M meets all specified electrical and mechanical parameters. Direct substitution is possible from a functional standpoint. However, the substitute part is Obsolete, and RoHS compliance status is not specified. Verify compliance requirements and product lifecycle support before implementation.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: capacitance (6800 pF), tolerance (±20%), voltage rating (25V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (0402/1005 Metric), mounting type (Surface Mount MLCC), physical dimensions (0.039" L x 0.020" W), maximum thickness (0.022"), and moisture sensitivity level (1/Unlimited).

Q: Does packaging format affect circuit board assembly?

A: Yes. The primary part uses Tape & Reel (TR) packaging, while the substitute uses Cut Tape (CT) & Digi-Reel® packaging. These formats have different handling, feeding, and storage characteristics. Assembly equipment compatibility and supply chain logistics must be evaluated.

Q: Why is the substitute part listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. While existing inventory may be available, future procurement cannot be guaranteed. Use of obsolete components requires long-term supply chain planning and inventory management.

Q: Are there compliance differences between the two parts?

A: The primary part is explicitly RoHS3 compliant. The substitute part does not have RoHS status specified in available data. Applications requiring RoHS certification must verify compliance status with the substitute part manufacturer before implementation.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for lower-volume or manual assembly. Digi-Reel® is a proprietary reel format. Equipment compatibility and assembly process requirements determine which format is appropriate.
