Equivalent & Substitute Parts for 5GAD47

Part Overview

The 5GAD47 is a 4700 pF ceramic capacitor rated at 1000V with Z5U temperature coefficient, manufactured by Vishay Sprague in a radial, disc package configuration. This component is designed for general-purpose applications requiring high-voltage ceramic capacitance in through-hole mounting. The 5GAD47 has been discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain the same electrical and mechanical specifications for seamless integration into existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5GAD47 is based on matching the following critical electrical parameters: capacitance value (4700 pF), tolerance (±20%), voltage rating (1000V), and temperature coefficient (Z5U). The mechanical requirements include through-hole mounting with radial, disc package configuration. Both the original part and substitute must maintain ROHS3 compliance and REACH unaffected status to ensure regulatory compatibility.

The identified substitute, S472M39Z5UN63J5R, satisfies all mandatory electrical specifications. Mechanical differences exist in physical dimensions and lead configuration, which must be evaluated for board layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The S472M39Z5UN63J5R serves as a direct electrical equivalent to the 5GAD47, matching all critical capacitive parameters and regulatory compliance requirements. Both components are ROHS3 compliant and REACH unaffected, ensuring regulatory compatibility in applications subject to these standards.

The primary consideration for selection is mechanical fit. The S472M39Z5UN63J5R exhibits larger physical dimensions (0.394" diameter vs. 0.290", and 0.551" height vs. 0.157") and different lead spacing (0.197" vs. 0.252"). These differences require verification against printed circuit board layout constraints, including hole spacing, component clearance, and thermal management requirements. The kinked lead style of the substitute may provide improved mechanical retention in certain mounting configurations.

The S472M39Z5UN63J5R is currently in active production status with substantial inventory availability, ensuring supply chain continuity for new designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can the S472M39Z5UN63J5R be used as a direct replacement for the 5GAD47?

A: Electrically, yes. Both components share identical capacitance (4700 pF), tolerance (±20%), voltage rating (1000V), and temperature coefficient (Z5U). However, mechanical compatibility must be confirmed. The substitute is larger in body diameter and height, and has different lead spacing and lead style. Board layout must accommodate these dimensional differences.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by matching capacitance value, tolerance, voltage rating, temperature coefficient, mounting type (through-hole), and package configuration (radial, disc). Regulatory compliance (ROHS3, REACH) must also align.

Q: Does the different lead spacing affect circuit performance?

A: Lead spacing affects only the physical mounting footprint on the printed circuit board. Electrically, the different spacing does not impact capacitive performance. Board redesign or component repositioning may be necessary to accommodate the 0.197" spacing of the substitute versus the 0.252" spacing of the original.

Q: Are there any thermal or environmental differences between these components?

A: The S472M39Z5UN63J5R specifies an operating temperature range of -30°C to 125°C. The 5GAD47 does not provide this specification. Both components use the Z5U temperature coefficient, which defines capacitance variation across the operating range. Application requirements should be evaluated against the specified operating range of the substitute.

Q: What is the significance of the kinked lead style on the substitute?

A: The kinked lead style on the S472M39Z5UN63J5R provides a formed configuration that may improve mechanical retention during insertion into through-hole mounting. This differs from the straight leads of the original part. Lead forming does not affect electrical performance but may influence assembly process compatibility.
