MLAST042SCG0R7AWNA01 Equivalent & Substitute Parts

Part Overview

The MLAST042SCG0R7AWNA01 is a 0.7 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. Equivalent and substitute parts are identified for applications requiring identical electrical and mechanical specifications, particularly when the primary part becomes unavailable or when alternative packaging formats are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MLAST042SCG0R7AWNA01 are qualified based on the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.7 pF
• Tolerance: ±0.05pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 01005 (0402 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Maximum thickness: 0.009" (0.22mm)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C ~ 125°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS3 compliance

Parts meeting all electrical, mechanical, and environmental specifications are classified as parametric equivalents. Packaging format variations (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility and are noted as secondary differentiators.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The MLAST042SCG0R7AWNA01 remains the primary specification for new designs. This part maintains Active product status and is available in Tape & Reel packaging format with full ROHS3 compliance and REACH Unaffected designation.

Equivalent Alternatives (Active Status): CQ0100ARNPO8BNR70 (YAGEO) and GJM0225C1ER70WB01L (Murata Electronics) are both Active products meeting all electrical and mechanical specifications. Both parts are ROHS3 compliant and suitable for new designs. CQ0100ARNPO8BNR70 is available in Tape & Reel format, while GJM0225C1ER70WB01L is supplied in Cut Tape format.

Legacy Alternative (Not For New Designs): TMK042CG0R7AD-W (Taiyo Yuden) is classified as Not For New Designs and should be used only for replacement or repair of existing assemblies. This part is available in Cut Tape packaging format.

All substitute parts maintain identical electrical performance, mechanical compatibility, and environmental operating specifications. Selection between alternatives should be based on packaging format requirements, inventory availability, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG0R7AD-W be used as a direct replacement for MLAST042SCG0R7AWNA01?

A: TMK042CG0R7AD-W is electrically and mechanically equivalent to MLAST042SCG0R7AWNA01. However, TMK042CG0R7AD-W carries Not For New Designs status and is supplied in Cut Tape format rather than Tape & Reel. Use this part only for repair or replacement of existing assemblies where the original part is unavailable.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape packaging supplies components on tape segments cut to specific lengths, typically for manual assembly or lower-volume applications. Both formats contain identical components with no electrical or mechanical differences.

Q: Are all substitute parts ROHS3 compliant?

A: MLAST042SCG0R7AWNA01, TMK042CG0R7AD-W, and GJM0225C1ER70WB01L are confirmed ROHS3 compliant. CQ0100ARNPO8BNR70 RoHS status is not specified in available documentation.

Q: Do substitute parts have the same operating temperature range?

A: All substitute parts operate across the identical temperature range of -55°C to 125°C, matching the primary part specification.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical package dimensions (01005/0402 Metric), footprint requirements, and mounting specifications. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is the significance of C0G/NP0 temperature coefficient?

A: C0G and NP0 designations indicate zero temperature coefficient, meaning capacitance remains stable across the operating temperature range. This specification is maintained across all substitute parts.

Q: Are there inventory considerations when selecting a substitute?

A: Inventory levels vary by part and supplier. MLAST042SCG0R7AWNA01 has 710 pieces in stock, TMK042CG0R7AD-W has 44,172 pieces, CQ0100ARNPO8BNR70 has 15,604 pieces, and GJM0225C1ER70WB01L has 22,090 pieces. Availability should be confirmed with component distributors for current project requirements.
