Parameter Comparison

Engineering Selection Recommendations

The 2JQ 1.5-R is the direct active equivalent for the obsolete 2JQ 1.5. Both parts maintain identical electrical and mechanical specifications, including current rating, voltage ratings, breaking capacity, and thermal characteristics. The 2JQ 1.5-R offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the 2JQ 1.5-R achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts carry equivalent international approvals (CE, CSA, cURus, PSE) and are suitable for applications requiring fast-blow protection in 2AG holder assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 2JQ 1.5-R be used as a direct replacement for the 2JQ 1.5?

A: Yes. The 2JQ 1.5-R is electrically and mechanically equivalent to the 2JQ 1.5. Both parts share identical current ratings (1.5 A), voltage ratings (350 V AC, 140 V DC), fuse type (cartridge, glass), response time (fast blow), package form factor (2AG, 5mm x 15mm), breaking capacity, and thermal operating range.

Q: What is the primary difference between these two parts?

A: The main difference is product status. The 2JQ 1.5 is obsolete, while the 2JQ 1.5-R is active. Additionally, the 2JQ 1.5-R is ROHS3 compliant, whereas the original part is RoHS non-compliant. The DC cold resistance differs slightly (0.056 Ohms vs. 0.058 Ohms), but this variation remains within acceptable engineering tolerances for fuse applications.

Q: Are there any compatibility concerns when substituting the 2JQ 1.5-R for the 2JQ 1.5?

A: No compatibility concerns exist. Both parts are designed for identical 2AG holder assemblies and maintain the same physical dimensions (5mm x 15mm). Electrical performance, including breaking capacity and melting I²t characteristics, is equivalent.

Q: What approvals do these fuses carry?

A: Both the 2JQ 1.5 and 2JQ 1.5-R carry CE, CSA, cURus, and PSE approvals, ensuring compliance with international safety standards.

Q: Is the 2JQ 1.5-R available in different packaging options?

A: The 2JQ 1.5-R is available in bulk packaging, whereas the original 2JQ 1.5 was supplied with standard packaging. Bulk packaging does not affect electrical or mechanical performance.
