MLAST042SCG1R2BWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG1R2BWNA01 is a 1.2 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is packaged in 01005 (0402 Metric) form factor and is classified as Active product status. Substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit alternative qualified manufacturers while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLAST042SCG1R2BWNA01 is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

• Capacitance value: 1.2 pF
• Tolerance: ±0.1pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 125°C
• Package type: 01005 (0402 Metric)
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Thickness: 0.009" (0.22mm) maximum
• Mounting type: Surface Mount, MLCC
• Moisture sensitivity: MSL 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All identified substitute parts meet these parameters without exception. Substitution does not require design modification, PCB layout changes, or requalification of assembly processes.

Parameter Comparison

Engineering Selection Recommendations

MLAST042SCG1R2BWNA01 (Primary Part) Current product status is Active. This part is suitable for new designs and ongoing production. Inventory availability is 1,062 pieces.

TVS042CG1R2BC-W (Taiyo Yuden Substitute) Product status is Not For New Designs. This part meets all electrical and mechanical specifications but is designated for legacy or existing design support only. Inventory availability is 70,678 pieces. Use this substitute only when the primary part is unavailable and design is not new.

CQ0100BRNPO8BN1R2 (YAGEO Substitute) Product status is Active. This part meets all electrical and mechanical specifications and is suitable for new designs. Inventory availability is 21,103 pieces. RoHS compliance status is not specified in available documentation.

GJM0225C1E1R2BB01L (Murata Electronics Substitute) Product status is Active. This part meets all electrical and mechanical specifications and is suitable for new designs. Inventory availability is 40,400 pieces. RoHS3 compliance is confirmed.

For new designs, select from CQ0100BRNPO8BN1R2, GJM0225C1E1R2BB01L, or the primary MLAST042SCG1R2BWNA01. For legacy designs, TVS042CG1R2BC-W is available as a secondary option.

Frequently Asked Questions (FAQ)

Q: Can TVS042CG1R2BC-W be used in new designs? A: TVS042CG1R2BC-W is designated as Not For New Designs. While it meets all electrical and mechanical parameters, it is intended for legacy or existing design support only. For new designs, use MLAST042SCG1R2BWNA01, CQ0100BRNPO8BN1R2, or GJM0225C1E1R2BB01L.

Q: Are all substitute parts identical in physical dimensions? A: Yes. All substitute parts share identical package specifications: 01005 (0402 Metric) with dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum thickness of 0.009" (0.22mm). No PCB layout modifications are required.

Q: Do all substitute parts have the same electrical specifications? A: Yes. All substitute parts are specified at 1.2 pF capacitance with ±0.1pF tolerance, 25V rated voltage, C0G/NP0 temperature coefficient, and -55°C ~ 125°C operating temperature range.

Q: What is the difference between C0G and NP0 designations? A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic. Both terms refer to capacitors with negligible capacitance change across the operating temperature range.

Q: Are all substitute parts RoHS3 compliant? A: MLAST042SCG1R2BWNA01, TVS042CG1R2BC-W, and GJM0225C1E1R2BB01L are confirmed ROHS3 Compliant. CQ0100BRNPO8BN1R2 RoHS compliance status is not specified in available documentation.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required.

Q: Can these parts be used interchangeably on the same PCB assembly? A: Yes. All substitute parts are mechanically and electrically equivalent. They can be used interchangeably without design changes, assembly process modifications, or requalification.

Q: Which substitute part has the highest inventory availability? A: TVS042CG1R2BC-W has the highest inventory at 70,678 pieces. However, due to its Not For New Designs status, it should be used only when other options are exhausted.
