PMT823014 Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The PMT823014 is a 3-pole gas discharge tube (GDT) rated for 230V DC spark-over voltage with an impulse discharge current capacity of 20kA (8/20µs). This component is designed for through-hole mounting in overvoltage protection applications. The PMT823014 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The SL1021B230X qualifies as a direct substitute for the PMT823014 based on the following critical parameters:

• Voltage Rating Match: Both parts specify 230V DC spark-over voltage
• Current Capacity Match: Both parts are rated for 20kA impulse discharge current (8/20µs)
• Pole Configuration Match: Both are 3-pole devices
• Mounting Compatibility: Both use through-hole mounting with identical package geometry (Axial Cylinder, 3 Lead T-Shape)
• Electrical Behavior Match: Both have fail-short characteristic set to "No"
• Compliance Alignment: Both are ROHS3 compliant with MSL rating of 1 (Unlimited)

The substitution is based on electrical equivalence and mechanical interchangeability. The SL1021B230X is manufactured by the same supplier (Littelfuse Inc.) and belongs to an active product series, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The SL1021B230X is the appropriate substitute for the obsolete PMT823014. Both parts are manufactured by Littelfuse Inc. and maintain identical electrical specifications and mechanical form factors. The SL1021B230X carries active product status, ensuring availability for new procurement and design revisions. Both parts meet ROHS3 compliance requirements and carry equivalent environmental ratings (MSL 1). The transition from PMT823014 to SL1021B230X requires no circuit redesign or PCB layout modifications, as the through-hole package geometry and electrical characteristics are fully compatible.

Frequently Asked Questions (FAQ)

Q: Can SL1021B230X be used as a direct replacement for PMT823014 in existing designs?

A: Yes. The SL1021B230X is electrically and mechanically equivalent to the PMT823014. Both parts share identical voltage ratings (230V), current capacity (20kA), pole configuration (3-pole), and through-hole package geometry. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The PMT823014 is classified as obsolete. The SL1021B230X is an active product from the same manufacturer with identical specifications, providing long-term procurement continuity.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Both are classified under the same ECCN (EAR99) and HTSUS code (8536.30.8000).

Q: Does packaging differ between these parts?

A: The PMT823014 packaging specification is not provided in the technical data. The SL1021B230X is supplied in tray packaging. This is a procurement consideration only and does not affect electrical or mechanical compatibility.

Q: Are there any electrical performance differences?

A: No. Both parts specify identical DC spark-over voltage (230V), impulse discharge current (20kA at 8/20µs), and fail-short characteristic (No). The electrical performance is equivalent.
