MSART042SCG7R7BWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG7R7BWRA01 is a 7.7 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V operation 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 and is ROHS3 compliant with MSL 1 moisture sensitivity rating.

Substitute parts become necessary when the primary part number reaches end-of-life status, when packaging format requirements differ (such as Cut Tape versus Tape & Reel), or when inventory availability from the original manufacturer becomes constrained. Identifying qualified equivalents ensures design continuity and supply chain flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG7R7BWRA01 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match exactly:

• Capacitance Value: 7.7 pF (no tolerance variation)
• Capacitance Tolerance: ±0.1pF
• Rated Voltage: 25V minimum
• Temperature Coefficient: C0G/NP0 (zero temperature coefficient)
• Operating Temperature Range: -55°C to 125°C
• Package Designation: 01005 (0402 Metric)
• Mounting Technology: Surface Mount MLCC
• Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1

Packaging format (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility and represents a logistics variable only. Parts meeting all electrical and mechanical criteria are classified as parametric equivalents regardless of packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

TMK042CG7R7BD-W qualifies as a parametric equivalent to MSART042SCG7R7BWRA01 based on complete electrical and mechanical parameter alignment. Both parts are manufactured by Taiyo Yuden and share identical capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications.

The primary distinction between these parts is product lifecycle status and packaging configuration. The MSART042SCG7R7BWRA01 maintains Active status and is supplied in Tape & Reel format, making it suitable for high-volume automated assembly operations. The TMK042CG7R7BD-W carries a "Not For New Designs" designation and is supplied in Cut Tape format, indicating this part number is in mature or declining production phase.

For new design implementations, the MSART042SCG7R7BWRA01 is the preferred selection due to its Active product status and standard Tape & Reel packaging compatibility with modern pick-and-place assembly equipment. The TMK042CG7R7BD-W remains electrically and mechanically interchangeable for existing designs or applications where Cut Tape packaging is acceptable and inventory availability is prioritized.

Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, eliminating compliance-related constraints on substitution decisions.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG7R7BD-W be used as a direct replacement for MSART042SCG7R7BWRA01 in existing circuit designs?

A: Yes. The TMK042CG7R7BD-W is electrically and mechanically equivalent. All critical parameters including capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, and package dimensions are identical. The parts are interchangeable at the component level.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated high-speed pick-and-place assembly. Cut Tape (CT) packaging supplies the same components on shorter tape segments, typically used for lower-volume manual assembly or when reel quantities exceed immediate requirements. Both formats contain identical components with no electrical or mechanical differences.

Q: Why does TMK042CG7R7BD-W have "Not For New Designs" status?

A: This designation indicates the part is in mature production phase and may have limited availability or planned discontinuation. While the part remains fully functional and compliant, Taiyo Yuden recommends using MSART042SCG7R7BWRA01 for new design implementations to ensure long-term supply continuity.

Q: Are there any thermal or frequency performance differences between these parts?

A: No. Both parts share identical C0G/NP0 temperature coefficient characteristics and operate across the same -55°C to 125°C temperature range. Frequency performance is determined by capacitance value and dielectric material, which are identical across both part numbers.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Both parts are ROHS3 compliant with MSL 1 moisture sensitivity rating. Interchangeability in high-reliability applications depends on specific qualification requirements beyond the provided parameters. Consult application-specific reliability standards and qualification documentation.

Q: What is the significance of the ±0.1pF tolerance specification?

A: The ±0.1pF tolerance represents the maximum allowable deviation from the nominal 7.7 pF capacitance value. This tight tolerance (approximately 1.3% of nominal value) is typical for C0G/NP0 ceramic capacitors and ensures stable performance in precision RF and timing circuits. Both parts meet this specification identically.
