2JQ 1 Equivalent & Substitute Parts

Part Overview

The 2JQ 1 is a 1 A, 350 V AC / 140 V DC fast-blow glass cartridge fuse in 2AG package format (5mm x 15mm). This component requires a compatible fuse holder for installation and is designed for circuit protection applications requiring rapid response to overcurrent conditions.

The 2JQ 1 is classified as obsolete. Locating active equivalent parts is necessary to ensure continued availability for new designs, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2JQ 1 is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 1 A (exact match required)
• Voltage Ratings: 350 V AC and 140 V DC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 2AG, 5mm x 15mm (exact match required)
• Breaking Capacity: 100 A AC / 150 A DC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Approval Agencies: CE, CSA, cURus, PSE (exact match required)

The 2JQ 1-R meets all substitution criteria and is classified as an active product, making it a direct equivalent for the obsolete 2JQ 1.

Parameter Comparison

Engineering Selection Recommendations

The 2JQ 1-R is the direct equivalent for the obsolete 2JQ 1. Both parts are manufactured by Bel Fuse Inc. and share identical electrical and mechanical specifications across all critical parameters: current rating, voltage ratings, fuse type, response time, package format, breaking capacity, and operating temperature range.

The 2JQ 1-R carries active product status, ensuring ongoing availability and supply chain continuity. Additionally, the 2JQ 1-R achieves ROHS3 compliance, whereas the original 2JQ 1 is non-compliant. For applications subject to RoHS requirements, the 2JQ 1-R is the appropriate selection.

Both parts maintain identical approval certifications (CE, CSA, cURus, PSE), confirming regulatory equivalence for protected circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 2JQ 1-R be used as a direct replacement for the 2JQ 1?

A: Yes. The 2JQ 1-R meets all electrical and mechanical specifications of the 2JQ 1, including current rating, voltage ratings, fuse type, response time, package format, breaking capacity, and operating temperature range.
