• Voltage Rating - DC: 600 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 100 A (exact match required)
• Melting I²t: 4.1 (exact match required)
• DC Cold Resistance: 0.093 Ohms (exact match required)

Mechanical Parameters:

• Mounting Type: Surface Mount (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: 2-SMD, Square End Block (exact match required)
• Size / Dimension: 0.520" L x 0.199" W x 0.199" H / 13.20mm x 5.05mm x 5.05mm (exact match required)

Environmental & Compliance Parameters:

• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

The substitute part TR-1350HV2-R meets all specified parameters and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 0ACJ-2000-TE and TR-1350HV2-R are active production parts with identical electrical, mechanical, and environmental specifications. Selection between these parts is based on the following factors:

Availability: The 0ACJ-2000-TE (Bel Fuse Inc.) has 1617 pieces in current stock inventory. The TR-1350HV2-R (Eaton - Electronics Division) has 1768 pieces in current stock inventory. Both parts demonstrate adequate supply availability.

Compliance & Certifications: Both parts are ROHS3 compliant, REACH unaffected, and carry cURus approval (0ACJ-2000-TE) or equivalent regulatory standing. Both parts meet the same environmental and safety standards for board mount fuse applications.

Packaging & Handling: Both parts are supplied in Tape & Reel (TR) packaging with MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling.

Interchangeability: The TR-1350HV2-R is a direct parametric equivalent to the 0ACJ-2000-TE and can be used as a substitute without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can TR-1350HV2-R be used as a direct replacement for 0ACJ-2000-TE in existing designs?

A: Yes. The TR-1350HV2-R is a parametric equivalent with identical electrical ratings (2 A, 350 V AC, 600 V DC), response time (fast blow), breaking capacity (100 A), and physical dimensions (0.520" L x 0.199" W x 0.199" H). Both parts use the same 2-SMD square end block package and are surface mount compatible. No circuit or PCB modifications are required.

Q: Are there any differences in approval agencies or certifications between these parts?

A: The 0ACJ-2000-TE carries cURus approval. The TR-1350HV2-R approval agency information is not specified in the provided data. Both parts are ROHS3 compliant and REACH unaffected. Verify specific approval requirements for your application if cURus certification is mandatory.

Q: What is the significance of the 0.093 Ohms DC cold resistance specification?

A: DC cold resistance is the measured resistance of the fuse element at room temperature before operation. The 0.093 Ohms specification is identical for both parts and indicates equivalent electrical characteristics and heat dissipation behavior during normal operation.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the 0ACJ-2000-TE and TR-1350HV2-R are rated for operating temperatures from -40°C to 125°C, making them suitable for industrial and automotive applications requiring extended temperature range operation.

Q: What does MSL 1 (Unlimited) mean for handling and storage?

A: MSL 1 (Unlimited) indicates that these parts have no moisture sensitivity limitations. They do not require special dry storage conditions, desiccant packaging, or bake-out procedures before soldering. Standard warehouse storage conditions are acceptable.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. Both parts are rated for 350 V AC and 600 V DC operation, allowing use in mixed-signal or dual-voltage applications. The fast blow response time applies to both AC and DC fault conditions.

Q: What is the melting I²t value and why is it important?

A: The melting I²t value of 4.1 represents the thermal energy required to melt the fuse element. This specification determines the fuse's response to overcurrent conditions and is critical for circuit protection coordination. Both parts have identical I²t values, ensuring equivalent protection characteristics.
