Substitute Part Grouping Explanation

Substitution eligibility for the TR2-S505SC-2-R is determined by strict equivalence across the following critical parameters:

• Current Rating: 2 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Series: S505 (exact match required)

The substitute part TR2/S505SC-2-R meets all equivalence criteria and is manufactured by the same supplier (Eaton - Electronics Division). Both parts are active products with full international certification coverage.

Parameter Comparison

Engineering Selection Recommendations

Both TR2-S505SC-2-R and TR2/S505SC-2-R are active products with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Compliance Status: Both parts carry full international certification coverage (BSI, CSA, cURus, VDE, PSE/JET, and additional agencies). The TR2/S505SC-2-R carries ROHS3 compliance, representing the latest RoHS standard iteration, while TR2-S505SC-2-R carries standard RoHS compliance. For applications requiring the most current environmental compliance documentation, TR2/S505SC-2-R is the preferred selection.

Inventory Availability: TR2-S505SC-2-R has 1064 pieces in stock. TR2/S505SC-2-R has 654 pieces in stock. Selection should account for project timeline and quantity requirements.

Electrical Performance: DC cold resistance values (0.0545 Ohms vs. 0.055 Ohms) and melting I²t values (9.6 vs. 9.83) are within equivalent operating ranges for this fuse category and do not affect circuit protection performance or compatibility.

Both parts are direct substitutes suitable for identical circuit protection applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can TR2/S505SC-2-R be used as a direct replacement for TR2-S505SC-2-R?

A: Yes. Both parts are identical in current rating (2 A), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), package dimensions (5mm x 20mm), and breaking capacity (1.5 kA). No circuit design changes are required.

Q: What is the difference between these two part numbers?

A: The primary differences are minor variations in DC cold resistance (0.0545 Ohms vs. 0.055 Ohms) and melting I²t (9.6 vs. 9.83), which fall within equivalent operating parameters for ceramic cartridge fuses. TR2/S505SC-2-R carries ROHS3 compliance versus standard RoHS compliance on TR2-S505SC-2-R. Both parts maintain identical electrical performance and safety certifications.

Q: Are both parts available in the same packaging format?

A: Yes. Both TR2-S505SC-2-R and TR2/S505SC-2-R are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Do both parts carry the same international certifications?

A: Yes. Both parts are certified by BSI, CCC/CQC, CSA, cURus, IMQ, KC, PSE/JET, SEMKO, and VDE. Full certification coverage is identical across both part numbers.

Q: Which part should be selected for new designs?

A: For new designs, TR2/S505SC-2-R is the recommended selection due to ROHS3 compliance status, representing the current environmental standard. Both parts are functionally equivalent and will perform identically in circuit protection applications.

Q: Can these fuses be used in applications rated for 250 V DC?

A: Yes. Both parts are rated for 250 V AC/DC operation, supporting both alternating and direct current applications at the specified voltage level.
