HT06BN472KN Equivalent & Substitute Parts

Part Overview

The HT06BN472KN is a 4700 pF ceramic capacitor manufactured by KEMET, rated for 50V operation with C0G/NP0 temperature coefficient and high-temperature capability (-55°C to 200°C). This radial through-hole component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the HT06BN472KN is determined by the following critical parameters:

Mandatory Matching Parameters:

Capacitance value: 4700 pF
Temperature coefficient: C0G/NP0
Mounting type: Through Hole
Package type: Radial
Operating temperature range: -55°C to 200°C minimum

Allowable Variation Parameters:

Voltage rating: Equal to or greater than 50V

Engineering Selection Recommendations

VCR40L472JGS as Primary Substitute:

The VCR40L472JGS is the designated equivalent for the obsolete HT06BN472KN based on the following engineering criteria:

Functional Equivalence: Identical capacitance (4700 pF) and temperature coefficient (C0G/NP0) ensure electrical performance parity in circuit applications.
Enhanced Specifications: The 500V voltage rating provides operational margin beyond the original 50V specification, and the ±5% tolerance offers improved precision compared to the ±10% original specification.
Product Status: The VCR40L472JGS maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity.
Compliance Considerations: The VCR40L472JGS is REACH Affected and RoHS non-compliant. Design teams must evaluate compliance requirements against the original HT06BN472KN specifications for regulatory alignment in target applications.
Physical Integration: The substitute component exhibits larger physical dimensions (0.350" L x 0.275" W versus 0.300" L x 0.150" W) and increased lead spacing (0.250" versus 0.200"). PCB layout verification is required to confirm mechanical fit within existing footprints.

Frequently Asked Questions (FAQ)

Q: Can the VCR40L472JGS be used as a direct replacement for the HT06BN472KN?

A: The VCR40L472JGS is electrically equivalent with identical capacitance and temperature coefficient. However, physical dimensions and lead spacing differ. PCB layout compatibility must be verified before implementation.

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

A: The 500V rating on the VCR40L472JGS provides operational margin in circuits originally designed for 50V. This does not affect functionality in 50V applications and may improve reliability margins.

Q: Does the improved tolerance (±5% vs ±10%) affect circuit performance?

A: The tighter tolerance of the VCR40L472JGS provides improved capacitance accuracy. In applications sensitive to capacitance variation, this represents an enhancement over the original specification.

Q: What are the lead spacing implications for PCB redesign?

A: The substitute part requires 0.250" (6.35mm) lead spacing compared to the original 0.200" (5.08mm). Existing PCB footprints designed for the HT06BN472KN will not accommodate the VCR40L472JGS without modification.

Q: Are there compliance differences between the original and substitute parts?

A: The VCR40L472JGS is REACH Affected and RoHS non-compliant, whereas the original HT06BN472KN specifications do not indicate these compliance statuses. Applications requiring specific regulatory compliance must evaluate these differences.

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

A: The VCR40L472JGS is currently available with 856 pieces in stock as new original inventory, providing immediate procurement availability.
