Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TR2-S505SC-1.6-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 1.6 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Slow Blow
• Package / Case: 5mm x 20mm (Axial)
• Mounting Type: Through Hole
• Breaking Capacity @ Rated Voltage: 1.5 kA
• DC Cold Resistance: 0.07 Ohms

The substitute part TR2/S505SC-1.6-R meets all mandatory parameters and is classified as a parametric equivalent. Both parts belong to the Eaton S505 series and share identical electrical and mechanical specifications, enabling direct substitution in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The TR2/S505SC-1.6-R is a direct parametric equivalent to the TR2-S505SC-1.6-R and qualifies for substitution in all applications where the main part is specified. Both components maintain Active product status and carry identical regulatory certifications across BSI, CCC/CQC, CSA, cULus, IMQ, KC, PSE/JET, SEMKO, and VDE standards.

Both parts are RoHS compliant, with the substitute offering ROHS3 compliance, indicating enhanced environmental and material standards. The melting I²t values (6.78 vs. 7.35) remain within acceptable tolerance for slow-blow ceramic fuse applications and do not affect functional equivalence.

Selection between these parts should be based on inventory availability and procurement lead times. The substitute part currently maintains higher stock levels (1123 pieces versus 757 pieces), making it suitable for high-volume production requirements or time-sensitive procurement scenarios.

Frequently Asked Questions (FAQ)

Q: Can TR2/S505SC-1.6-R be used as a direct replacement for TR2-S505SC-1.6-R?

A: Yes. Both parts are parametric equivalents with identical current ratings (1.6 A), voltage ratings (250 V AC), fuse type (ceramic cartridge), response time (slow blow), package dimensions (5mm x 20mm axial), and breaking capacity (1.5 kA). They are interchangeable in circuit protection applications.

Q: Are there differences in regulatory compliance between these parts?

A: Both parts carry identical certifications from BSI, CCC/CQC, CSA, cULus, IMQ, KC, PSE/JET, SEMKO, and VDE. The substitute part includes ROHS3 compliance, which represents an enhanced environmental standard compared to standard RoHS compliance on the main part.

Q: What is the significance of the melting I²t difference (6.78 vs. 7.35)?

A: The melting I²t values indicate thermal energy absorption characteristics. The difference of 0.57 units is within acceptable tolerance for slow-blow ceramic fuses and does not affect functional equivalence or circuit protection performance in standard applications.

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

A: Yes. Both TR2-S505SC-1.6-R and TR2/S505SC-1.6-R are supplied in Tape & Reel (TR) packaging, ensuring compatibility with automated assembly equipment and standard component handling procedures.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory levels, supplier availability, and procurement timelines. Both maintain Active product status and identical electrical specifications.

Q: Do these fuses require any special handling or installation considerations?

A: Both parts are through-hole ceramic cartridge fuses with identical form factors (5mm x 20mm axial). Standard PCB mounting procedures and soldering practices apply to both components without modification.
