UP050CH620J-KFCZ Equivalent & Substitute Parts

Part Overview

The UP050CH620J-KFCZ is a 62 pF ceramic capacitor rated at 50V with C0H temperature coefficient, manufactured by Taiyo Yuden in axial through-hole configuration. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements. The part maintains general-purpose application suitability with ±5% capacitance tolerance and operates across -25°C to 85°C temperature range.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	62 pF	Primary electrical specification; must match exactly
Tolerance	±5%	Defines acceptable capacitance variation; critical for circuit performance
Voltage Rating	50V	Minimum voltage requirement; substitute must meet or exceed
Temperature Coefficient	C0H	Defines capacitance stability across temperature range
Mounting Type	Through Hole	Determines PCB assembly compatibility
Package Type	Axial	Physical form factor; must be compatible with board layout
Operating Temperature	-25°C ~ 85°C	Defines functional temperature range
Product Status	Obsolete	Justifies need for active alternative

Substitute Part Grouping Explanation

Substitution of the UP050CH620J-KFCZ is based on the following electrical and mechanical compatibility criteria:

Mandatory Matching Parameters:

Capacitance value: 62 pF (exact match required)
Tolerance: ±5% (ensures circuit design specifications are maintained)
Mounting type: Through Hole (PCB assembly compatibility)
Package type: Axial (physical form factor compatibility)

Allowable Variation Parameters:

Voltage rating: Substitute must equal or exceed 50V minimum
Temperature coefficient: Substitute with C0G/NP0 coefficient acceptable (superior stability compared to C0H)
Operating temperature range: Substitute with extended range acceptable
Product status: Active status preferred for long-term availability

The SA102A620JAR meets all mandatory matching criteria while providing enhanced electrical characteristics through higher voltage rating (200V vs. 50V) and superior temperature coefficient stability (C0G/NP0 vs. C0H).

Engineering Selection Recommendations

Primary Substitute: SA102A620JAR

The SA102A620JAR is the qualified substitute for UP050CH620J-KFCZ based on the following engineering criteria:

Electrical Equivalence: Identical capacitance (62 pF) and tolerance (±5%) ensure circuit design specifications are preserved without recalculation or revalidation.
Voltage Margin: The 200V rating provides 4× safety margin over the original 50V specification, enhancing reliability in applications subject to transient overvoltage conditions.
Temperature Stability: C0G/NP0 temperature coefficient provides superior capacitance stability compared to C0H, reducing temperature-dependent circuit drift.
Product Status: Active production status ensures long-term availability, supply chain continuity, and consistent manufacturing quality.
Compliance Certifications: ROHS3 compliance and REACH unaffected status align with current regulatory requirements for electronic components in regulated markets.
Physical Compatibility: Identical through-hole axial package with straight leads ensures direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can SA102A620JAR be used as a direct replacement for UP050CH620J-KFCZ?

A: Yes. Both components share identical capacitance (62 pF), tolerance (±5%), mounting type (through hole), and package configuration (axial). The substitute meets all mandatory electrical and mechanical compatibility requirements for direct substitution.

Q: What is the significance of the higher 200V rating on the substitute part?

A: The SA102A620JAR's 200V rating exceeds the original 50V specification, providing increased safety margin and reliability. This does not affect circuit operation in applications designed for 50V or lower; it only enhances component robustness against voltage transients.

Q: How does the C0G/NP0 temperature coefficient differ from C0H?

A: C0G/NP0 provides superior temperature stability with minimal capacitance variation across the operating temperature range. C0H exhibits greater capacitance drift with temperature. For applications requiring stable capacitance performance across temperature extremes, C0G/NP0 is advantageous.

Q: Are there physical size differences between these components?

A: Yes. The SA102A620JAR measures 0.100" diameter × 0.170" length (2.54mm × 4.32mm), compared to the UP050CH620J-KFCZ at 0.087" diameter × 0.126" length (2.20mm × 3.20mm). PCB layout must accommodate the slightly larger substitute component dimensions.

Q: What is the inventory status for the substitute part?

A: SA102A620JAR has 961 pieces in current stock as active production inventory, ensuring immediate availability and ongoing supply continuity.

Q: Does the substitute part meet current environmental compliance standards?

A: Yes. SA102A620JAR is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in regulated markets.
