2JQ 6 Equivalent & Substitute Parts

Part Overview

The 2JQ 6 is a fast-blow glass cartridge fuse rated at 6 A, 350 V AC, and 140 V DC, manufactured by Bel Fuse Inc. in the 2AG form factor (5mm x 15mm). This component is classified as obsolete, indicating discontinuation from active production. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure design continuity, and support legacy equipment requiring this specific fuse rating and electrical characteristics.

Substitute Part Grouping Explanation

Substitution of the 2JQ 6 is determined by strict equivalence across the following critical parameters:

• Current Rating: 6 A (exact match required)
• Voltage Ratings: 350 V AC and 140 V DC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 2AG, 5mm x 15mm (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 100A AC, 150A DC (exact match required)
• Melting I²t: 35 (exact match required)

The 2JQ 6-R meets all substitution criteria as a direct equivalent. The primary distinction between the main part and its substitute is product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The 2JQ 6-R is the direct substitute for the obsolete 2JQ 6. Both parts are manufactured by Bel Fuse Inc. and share identical electrical and mechanical specifications. The 2JQ 6-R maintains active product status and offers improved regulatory compliance through ROHS3 certification, whereas the original 2JQ 6 is RoHS non-compliant. Both parts carry equivalent international approvals (CE, CSA, cURus, PSE) and are suitable for applications requiring 6 A fast-blow protection at 350 V AC or 140 V DC. Selection of the 2JQ 6-R is appropriate for new designs and legacy system maintenance where component availability is a consideration.

Frequently Asked Questions (FAQ)

Q: Can the 2JQ 6-R be used as a direct replacement for the 2JQ 6?

A: Yes. The 2JQ 6-R is electrically and mechanically identical to the 2JQ 6. Both parts have the same current rating, voltage ratings, response time, breaking capacity, and physical dimensions. The substitute is suitable for direct installation in existing circuits.

Q: What is the difference between the 2JQ 6 and 2JQ 6-R?

A: The primary differences are product status and regulatory compliance. The 2JQ 6 is obsolete and RoHS non-compliant, while the 2JQ 6-R is active and ROHS3 compliant. Electrical and mechanical performance are identical.

Q: Are there any compatibility concerns when substituting the 2JQ 6-R for the 2JQ 6?

A: No compatibility concerns exist. Both parts use the 2AG form factor (5mm x 15mm) and require the same holder. They are pin-for-pin and functionally equivalent.

Q: What certifications apply to both the 2JQ 6 and 2JQ 6-R?

A: Both parts carry CE, CSA, cURus, and PSE approvals, ensuring compliance with international safety standards.

Q: Is the 2JQ 6-R suitable for new product designs?

A: Yes. The 2JQ 6-R is an active product with current manufacturing support and improved RoHS compliance, making it the appropriate choice for new designs requiring 6 A fast-blow protection at 350 V AC or 140 V DC.
