CV50K07B Equivalent & Substitute Parts Reference

Part Overview

The CV50K07B is a metal oxide varistor (MOV) manufactured by Stackpole Electronics Inc, classified as a Transient Voltage Suppressor (TVS). This through-hole disc component is designed for transient voltage protection in AC and DC circuits operating at 50V (Vrms) nominal levels. The part is currently in Active product status with 1031 units in stock.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when design requirements permit functional alternatives within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the CV50K07B are identified based on strict electrical and mechanical parameter matching within the Stackpole Electronics CV series. The substitution logic is based on the following critical parameters:

Electrical Parameters (Must Match):

• Maximum AC Volts: 50 V
• Maximum DC Volts: 65 V
• Varistor Voltage (Typical): 82 V
• Current - Surge: 1.2 kA
• Energy: 6.8 J
• Capacitance @ 1 kHz: 820 pF

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: Disc 7mm
• Number of Circuits: 1

Operational Parameters (Must Match):

• Operating Temperature Range: -40°C to 85°C
• Product Status: Active

The CV50K07T is classified as a parametric equivalent to the CV50K07B. Both parts share identical electrical specifications, mechanical form factors, and operational characteristics. The difference between these part numbers reflects packaging or distribution channel variations rather than functional or performance differences.

Engineering Selection Recommendations

Both CV50K07B and CV50K07T are Active status products manufactured by Stackpole Electronics Inc and are fully interchangeable based on provided electrical and mechanical specifications. Selection between these part numbers should be based on:

Availability and Inventory: CV50K07T currently has 1042 units in stock compared to 1031 units for CV50K07B. Either part may be selected based on procurement lead time and inventory requirements.

Compliance and Certifications: Both parts share identical ECCN (EAR99) and HTSUS (8533.40.4000) classifications, ensuring equivalent regulatory and trade compliance status.

Supply Chain Continuity: When either part number experiences supply constraints, the alternative may be substituted without design modification, circuit re-qualification, or performance degradation.

No additional technical criteria beyond those provided in the specification parameters should be introduced into the selection process.

Frequently Asked Questions (FAQ)

Q: Can CV50K07T be used as a direct replacement for CV50K07B in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (50V AC, 65V DC, 82V typical varistor voltage, 1.2 kA surge current), mechanical form factors (7mm disc through-hole), and operating temperature ranges (-40°C to 85°C). No circuit modification is required.

Q: What is the difference between CV50K07B and CV50K07T?

A: The difference between these part numbers reflects packaging or distribution channel designation rather than functional or performance differences. All electrical and mechanical parameters are identical.

Q: Are both parts currently in production?

A: Yes. Both CV50K07B and CV50K07T maintain Active product status with Stackpole Electronics Inc.

Q: Do these parts have the same physical dimensions?

A: Yes. Both parts use identical 7mm disc through-hole packaging and mounting configuration.

Q: Can I mix CV50K07B and CV50K07T in the same production batch?

A: Yes. Since both parts are parametric equivalents with identical specifications, they may be used interchangeably in the same circuit design and production environment.

Q: What compliance certifications apply to these parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8533.40.4000) classifications.

Q: What is the operating temperature range for these varistors?

A: Both CV50K07B and CV50K07T operate across -40°C to 85°C ambient temperature range.
