Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP025CH1R5D-A-BZ is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must match: 1.5 pF
• Tolerance must be equivalent or tighter: ±0.5pF
• Voltage rating must equal or exceed the application requirement: minimum 50V

Mechanical Compatibility:

• Mounting type must be Through Hole
• Package type must be Axial
• Lead style must be Straight

Regulatory & Environmental:

• RoHS3 compliance required
• Moisture Sensitivity Level must be compatible with storage and handling conditions

The identified substitute part C410C159DAG5TA7200 meets all critical electrical parameters with enhanced voltage rating (250V) and improved temperature coefficient stability (C0G/NP0), while maintaining mechanical and regulatory compatibility.

Parameter Comparison

Engineering Selection Recommendations

The C410C159DAG5TA7200 serves as a direct functional substitute for the obsolete UP025CH1R5D-A-BZ based on the following criteria:

Electrical Equivalence: Both parts maintain identical capacitance (1.5 pF) and tolerance (±0.5pF). The substitute provides a higher voltage rating (250V versus 50V), which is compatible with applications designed for the original 50V specification and provides additional design margin.

Mechanical Compatibility: Both components utilize axial through-hole mounting with straight leads, ensuring direct board-level compatibility without circuit redesign.

Regulatory Compliance: Both parts are ROHS3 compliant and carry EAR99 ECCN classification, meeting current environmental and export control requirements.

Product Status: The substitute part is active in production with established supply chain availability (1084 pcs in stock), whereas the original part is obsolete. This transition ensures long-term component availability for production and field service applications.

Temperature Performance: The substitute exhibits an extended operating temperature range (-55°C ~ 125°C) and C0G/NP0 temperature coefficient, providing superior stability compared to the original CH coefficient specification.

Frequently Asked Questions (FAQ)

Q: Can the C410C159DAG5TA7200 be used as a direct replacement for the UP025CH1R5D-A-BZ?

A: Yes. Both parts share identical capacitance (1.5 pF), tolerance (±0.5pF), axial through-hole mounting, and straight lead configuration. The substitute is electrically and mechanically compatible with applications designed for the original part.

Q: What is the impact of the higher voltage rating (250V vs. 50V) on circuit performance?

A: The higher voltage rating does not negatively impact circuit performance. Capacitors operate within their rated voltage range; a 250V-rated capacitor functions identically to a 50V-rated capacitor when both are operated at 50V or below. The higher rating provides additional safety margin and design flexibility.

Q: Are there physical size differences between these parts?

A: Yes. The substitute (C410C159DAG5TA7200) measures 0.095" Dia x 0.170" L (2.41mm x 4.32mm), compared to the original 0.079" Dia x 0.091" L (2.00mm x 2.30mm). PCB layout verification is required to confirm fit within available board space.

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

A: C0G/NP0 represents a superior temperature stability specification with minimal capacitance variation across temperature extremes. This provides enhanced performance consistency in temperature-sensitive applications compared to the CH coefficient of the original part.

Q: Are both parts RoHS compliant?

A: Yes. Both the UP025CH1R5D-A-BZ and C410C159DAG5TA7200 are ROHS3 compliant, meeting current environmental and hazardous substance restriction requirements.

Q: What is the difference in Moisture Sensitivity Level (MSL) between the parts?

A: The original part carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The substitute lists MSL as Not Applicable, indicating equivalent or superior moisture resistance. Both are suitable for standard storage and handling conditions.

Q: Is the substitute part currently available?

A: Yes. The C410C159DAG5TA7200 is classified as Active with 1084 pcs in stock, ensuring reliable procurement availability compared to the obsolete original part.
