Substitute Part Grouping Explanation
Substitute parts for the MSASH31LSB7105KTNA01 are classified into two categories based on their relationship to the main part:
Upgrade Substitutes are parts that meet or exceed the electrical and mechanical specifications of the main part while offering additional certifications or enhanced product status. These parts maintain identical capacitance (1 µF), tolerance (±10%), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package dimensions (1206/3216 Metric), and MSL rating (1). Upgrade substitutes include AEC-Q200 automotive qualification, which the main part does not specify. These parts are suitable for direct replacement in applications requiring automotive-grade components or where enhanced reliability certifications are mandated.
Parametric Equivalents are parts that match all critical electrical parameters and physical dimensions but may differ in product status, packaging format, or application focus. These parts maintain identical capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, package type, and MSL rating. Parametric equivalents are suitable for applications where the specific application classification (automotive, bypass, decoupling, SMPS filtering, or general purpose) does not impose restrictions on component selection.
The substitution logic is based strictly on the following key parameters:
- Capacitance value (1 µF)
- Tolerance (±10%)
- Voltage rating (100V)
- Temperature coefficient (X7R)
- Operating temperature range (-55°C ~ 125°C)
- Package type and dimensions (1206/3216 Metric)
- Moisture sensitivity level (MSL 1)
- RoHS and REACH compliance status

Frequently Asked Questions (FAQ)
Q: What electrical parameters must match for a part to be considered a direct substitute for the MSASH31LSB7105KTNA01?
A: A direct substitute must match the following electrical parameters: 1 µF capacitance, ±10% tolerance, 100V voltage rating, X7R temperature coefficient, and -55°C to 125°C operating temperature range. All listed substitute parts meet these criteria.
Q: Can I use a part with AEC-Q200 rating in place of the MSASH31LSB7105KTNA01 in a general purpose application?
A: Yes. AEC-Q200 rated parts meet or exceed the electrical and reliability specifications of general purpose parts. Parts with AEC-Q200 certification (AC1206KKX7R0BB105, C1206C105K1RACAUTO, CGA5L2X7R2A105K160AA, CL31B105KCHVPNE) are suitable for any application where the main part is specified.
Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?
A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments, typically used for lower-volume orders or mixed-component kits. Both formats contain identical components; the difference is in delivery and handling format.
Q: Are all substitute parts ROHS3 compliant and REACH unaffected?
A: Yes. All substitute parts listed carry ROHS3 compliance and REACH Unaffected status, matching the environmental and regulatory compliance of the main part.
Q: Can I use C3216X7R2A105K160AM or GCM31CR72A105KA03L in new product designs?
A: No. Both C3216X7R2A105K160AM (TDK Corporation) and GCM31CR72A105KA03L (Murata Electronics) carry "Not For New Designs" product status. These parts are restricted to replacement and legacy applications only. For new designs, select from parts with Active product status.
Q: What is the Moisture Sensitivity Level (MSL) rating, and why is it important?
A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry MSL 1 rating, eliminating moisture-related handling constraints.
Q: Are there any differences in physical dimensions between the main part and substitute parts?
A: No. All parts, including the main part and all substitutes, share identical physical dimensions: 1206 (3216 Metric) package, 0.126" L x 0.063" W (3.20mm x 1.60mm), with maximum thickness of 0.071" (1.80mm).
Q: Which substitute part has the highest inventory availability?
A: C3216X7R2A105K160AM (TDK Corporation) has the highest inventory with 350,066 pieces in stock. However, this part carries "Not For New Designs" status. For new designs with high availability, C3216X7R2A105K160AA (TDK Corporation) offers 114,100 pieces with Active status.
