MSART042SCG4R7BWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG4R7BWRA01 is a 4.7 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 supplied in Tape & Reel (TR) packaging. The part is currently in Active product status with 708 units in stock.

Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, and temperature coefficient) and mechanical compatibility (package type, mounting method, and physical dimensions). Substitute parts enable design flexibility, support supply chain continuity, and provide alternative sourcing options when the primary part becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG4R7BWRA01 is determined by strict equivalence across the following parameters:

Electrical Parameters (Critical):

Capacitance value: 4.7 pF
Tolerance: ±0.1pF
Voltage rating: 25V
Temperature coefficient: C0G/NP0

Mechanical Parameters (Critical):

Package type: 01005 (0402 Metric)
Mounting method: 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

All identified substitute parts match these parameters exactly. Packaging format (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility and represents a logistical distinction only.

Engineering Selection Recommendations

Primary Selection (MSART042SCG4R7BWRA01): The main part is recommended for new designs. It maintains Active product status, ensuring long-term availability and manufacturer support. Current inventory of 708 units supports immediate procurement requirements.

Secondary Selection (CQ0100BRNPO8BN4R7): The YAGEO CQ0100BRNPO8BN4R7 is a fully qualified substitute with Active product status. This part provides an alternative sourcing channel and demonstrates the highest inventory availability at 20,347 units. It is suitable for both new designs and production continuity. The part includes High Q feature designation.

Tertiary Selection (TMK042CG4R7BD-W): The Taiyo Yuden TMK042CG4R7BD-W is electrically and mechanically equivalent but carries Not For New Designs product status. This part is suitable for legacy design support, maintenance, and repair applications only. It is not recommended for new product development. Packaging is supplied in Cut Tape (CT) format rather than Tape & Reel (TR).

All three parts are ROHS3 compliant and operate across the identical temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG4R7BD-W be used in new designs? A: No. TMK042CG4R7BD-W carries Not For New Designs product status. Use MSART042SCG4R7BWRA01 or CQ0100BRNPO8BN4R7 for new product development.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging? A: Tape & Reel and Cut Tape are packaging and delivery formats only. They do not affect electrical performance or mechanical compatibility. TR packaging is supplied on continuous reels for automated assembly. CT packaging is supplied in cut segments. Component specifications remain identical.

Q: Are all substitute parts RoHS3 compliant? A: Yes. MSART042SCG4R7BWRA01, TMK042CG4R7BD-W, and CQ0100BRNPO8BN4R7 are all ROHS3 compliant.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. All three parts share identical electrical specifications (4.7 pF, ±0.1pF, 25V, C0G/NP0), identical mechanical dimensions (01005/0402 Metric package), and identical operating temperature range (-55°C ~ 125°C). They are pin-compatible and footprint-compatible.

Q: What is the Moisture Sensitivity Level (MSL) for these parts? A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part has the highest inventory availability? A: CQ0100BRNPO8BN4R7 has 20,347 units in stock, compared to 708 units for MSART042SCG4R7BWRA01 and 3,731 units for TMK042CG4R7BD-W.

Q: Are there any differences in operating temperature range between the parts? A: No. All three parts operate across -55°C to 125°C.

Q: What does the High Q feature on CQ0100BRNPO8BN4R7 indicate? A: High Q indicates superior quality factor characteristics for this YAGEO part. This feature does not affect substitution eligibility but may provide performance advantages in high-frequency or precision applications.
