Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAASU105SB7102MFNA01 is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Capacitance value: 1000 pF
• Tolerance: ±20%
• Voltage rating: 50V
• Temperature coefficient: X7R
• Operating temperature range: -55°C ~ 125°C

Critical 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)

Compliance & Certification:

• AEC-Q200 automotive qualification
• ROHS3 compliance
• Moisture Sensitivity Level 1

All identified substitute parts maintain identical values across these parameters, ensuring direct functional and mechanical interchangeability in automotive applications.

Engineering Selection Recommendations

Primary Selection (Active Status): The MAASU105SB7102MFNA01 remains the primary specification for new designs. This part carries active product status from Taiyo Yuden with 881 pieces in current inventory.

Alternative Selections (Active Status): The following parts are suitable for direct substitution and carry active product status:

• C0402C102M5RACAUTO (KEMET): Active status with 18,565 pieces in inventory. Suitable for automotive bypass and decoupling applications.
• CGA2B2X7R1H102M050BA (TDK Corporation): Active status with 55,054 pieces in inventory. Qualified for automotive applications.
• GCM155R71H102MA37D (Murata Electronics): Active status with 5,855 pieces in inventory. Qualified for automotive applications.

Legacy Selection (Not For New Designs):

• UMF105B7102MVHF (Taiyo Yuden): Carries "Not For New Designs" status. This part is electrically and mechanically equivalent but should not be selected for new design implementations. Existing inventory of 38,491 pieces may be used for legacy system support or maintenance applications only.

All substitute parts maintain identical electrical performance, mechanical compatibility, automotive qualification (AEC-Q200), and regulatory compliance (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can I substitute the MAASU105SB7102MFNA01 with any of the listed equivalent parts?

A: Yes, all listed parts are electrically and mechanically equivalent. However, the UMF105B7102MVHF carries "Not For New Designs" status and should only be used for legacy applications. For new designs, select from C0402C102M5RACAUTO, CGA2B2X7R1H102M050BA, or GCM155R71H102MA37D.

Q: What determines if a part is a valid substitute?

A: A valid substitute must match all critical parameters: 1000 pF capacitance, ±20% tolerance, 50V rating, X7R temperature coefficient, -55°C to 125°C operating range, 0402 (1005 Metric) package, surface mount MLCC mounting type, identical physical dimensions, AEC-Q200 qualification, ROHS3 compliance, and MSL 1 rating.

Q: Are there any differences in performance between the main part and substitutes?

A: No. All parts listed maintain identical electrical specifications, temperature performance, voltage ratings, and tolerance values. They are functionally interchangeable in automotive applications.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical 0402 (1005 Metric) package dimensions (0.039" L x 0.020" W, 0.022" maximum thickness) and surface mount MLCC mounting type, ensuring direct PCB footprint compatibility.

Q: What is the significance of the "Not For New Designs" status on the UMF105B7102MVHF?

A: This designation indicates the manufacturer has discontinued active development and recommends against using this part in new product designs. While electrically equivalent, it should be reserved for maintenance, repair, or legacy system support only.

Q: Are all substitute parts automotive qualified?

A: Yes. All listed parts carry AEC-Q200 qualification, confirming suitability for automotive applications with appropriate reliability and quality standards.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. All parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
