Substitute Part Grouping Explanation

Substitution eligibility for the MSAST042SCG010AWNA01 is determined by strict equivalence across the following parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 1 pF
• Tolerance: ±0.05 pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G/NP0
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 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)

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape) and product status classification, provided all electrical, mechanical, and compliance parameters remain identical. The substitute parts identified below satisfy all substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MSAST042SCG010AWNA01): The MSAST042SCG010AWNA01 maintains Active product status and is the recommended selection for new designs. This part is supplied in Tape & Reel packaging, suitable for automated assembly processes. Current inventory of 907 pieces supports immediate procurement.

Secondary Selection (CQ0100ARNPO8BN1R0): The CQ0100ARNPO8BN1R0 manufactured by YAGEO is an Active product with full electrical and mechanical equivalence to the primary part. This substitute is available in Cut Tape and Digi-Reel® packaging formats. Inventory of 20,189 pieces provides extended availability. The CQ series includes High Q characteristics. This part is suitable for new designs and serves as a direct functional replacement.

Tertiary Selection (TMK042CG010AD-W): The TMK042CG010AD-W manufactured by Taiyo Yuden is classified as Not For New Designs. While electrically and mechanically equivalent, this part is designated for legacy or existing design support only. Inventory of 95,804 pieces is available in Cut Tape packaging. This part should not be selected for new product development.

All three parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and identical electrical performance within the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG010AD-W be used in new designs? A: No. The TMK042CG010AD-W is classified as Not For New Designs. For new product development, select either MSAST042SCG010AWNA01 or CQ0100ARNPO8BN1R0, both of which maintain Active product status.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging is supplied on continuous carrier tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) packaging is supplied as individual tape segments, suitable for lower-volume applications or manual assembly. Both formats contain identical components with identical electrical specifications.

Q: Are all three parts electrically interchangeable? A: Yes. All three parts—MSAST042SCG010AWNA01, TMK042CG010AD-W, and CQ0100ARNPO8BN1R0—are electrically interchangeable. Each maintains 1 pF capacitance, ±0.05 pF tolerance, 25V rating, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range.

Q: Do all substitute parts fit the same PCB footprint? A: Yes. All three parts use the identical 01005 (0402 Metric) package with dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum thickness of 0.009" (0.22mm). PCB footprints are directly interchangeable.

Q: What is the significance of the High Q feature in CQ0100ARNPO8BN1R0? A: High Q indicates lower dielectric loss in the CQ0100ARNPO8BN1R0. This characteristic may provide performance benefits in high-frequency or precision applications, though all three parts meet the same electrical specifications for capacitance, tolerance, and voltage rating.

Q: Are all parts ROHS3 compliant? A: Yes. MSAST042SCG010AWNA01, TMK042CG010AD-W, and CQ0100ARNPO8BN1R0 are all ROHS3 compliant with unlimited moisture sensitivity (MSL 1).

Q: Which part should be selected for immediate procurement? A: MSAST042SCG010AWNA01 is recommended for immediate procurement due to Active product status and suitability for new designs. If supply constraints occur, CQ0100ARNPO8BN1R0 provides an equivalent alternative with higher current inventory levels.
