TR2/C515-1-R Equivalent & Substitute Parts

Part Overview

The TR2/C515-1-R is a 1 A, 250 V AC slow-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This through-hole fuse is designed for general-purpose circuit protection in AC applications and is classified as Active product status. The component is housed in a 2AG package (5mm x 15mm axial configuration) and is RoHS Compliant with CSA and UL approval certifications.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturers. The availability of alternative sources ensures supply chain continuity and design flexibility for applications requiring this fuse specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TR2/C515-1-R is determined by strict alignment of the following critical parameters:

Mandatory Matching Criteria:

• Current Rating: 1 A (exact match required)
• Voltage Rating - AC: 250 V (minimum requirement)
• Response Time: Slow Blow (application-specific requirement)
• Fuse Type: Cartridge, Glass (construction compatibility)
• Mounting Type: Through Hole (assembly compatibility)
• Breaking Capacity: 35 A @ Rated Voltage (fault protection capability)

Acceptable Variation Parameters:

• Package dimensions within mechanical tolerance for 2AG standard
• DC voltage rating (if present) does not disqualify AC-rated substitutes
• Approval agencies may differ provided CSA or UL certification is maintained
• RoHS compliance status (both parts must be compliant or both non-compliant)

The substitute part 0230001.MXP (Littelfuse Inc.) meets all mandatory criteria and is therefore classified as an equivalent substitute for the TR2/C515-1-R.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (TR2/C515-1-R - Eaton):

• Use when Eaton component availability and supply chain continuity are prioritized
• Active product status ensures ongoing manufacturer support
• CSA and UL certifications meet North American regulatory requirements
• Established design history in existing applications

Substitute Selection (0230001.MXP - Littelfuse):

• Use when Littelfuse supply chain or inventory availability is advantageous
• Expanded approval certifications (CE, PSE) provide additional market flexibility
• Defined operating temperature range (-55°C ~ 125°C) supports wider environmental applications
• Active product status ensures ongoing manufacturer support
• Both RoHS compliant; ROHS3 designation indicates current compliance standard

Critical Consideration: The melting I²t value differs between parts (14.289 vs. 5.64). This parameter affects thermal response characteristics. For applications with specific thermal design requirements, verify that the substitute part's thermal profile aligns with circuit protection strategy before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 0230001.MXP substitute directly for the TR2/C515-1-R in existing designs?

A: Yes, for AC applications at 250 V with 1 A current requirements. Both parts are slow-blow glass cartridge fuses with identical current and voltage ratings, matching breaking capacity, and equivalent through-hole mounting. Physical dimensions are within 2AG standard tolerance (TR2/C515-1-R: 5.50mm x 15.20mm; 0230001.MXP: 4.50mm x 14.50mm).

Q: Does the DC voltage rating on the 0230001.MXP affect its use in AC-only circuits?

A: No. The 125 V DC rating on the Littelfuse part does not impact AC application performance. The 250 V AC rating is the controlling specification for AC circuits. The presence of a DC rating indicates broader application capability but does not restrict AC use.

Q: What is the significance of the different melting I²t values?

A: Melting I²t (14.289 for Eaton vs. 5.64 for Littelfuse) describes the thermal energy required to melt the fuse element. The Littelfuse part exhibits faster thermal response. For applications with specific inrush current profiles or thermal design margins, confirm that the substitute part's thermal characteristics remain compatible with circuit protection requirements.

Q: Are both parts RoHS compliant?

A: Yes. The TR2/C515-1-R is RoHS Compliant. The 0230001.MXP is ROHS3 Compliant, indicating compliance with the current RoHS 3 standard. Both parts meet RoHS requirements for restricted substance elimination.

Q: Which certifications are common to both parts?

A: Both parts hold CSA and UL certifications, meeting North American regulatory requirements. The Littelfuse part additionally carries CE and PSE certifications, providing expanded geographic compliance.

Q: Are there packaging differences between these parts?

A: The TR2/C515-1-R is supplied in Tape & Reel (TR) packaging. The 0230001.MXP is supplied in Bulk packaging. This affects procurement and assembly processes but does not impact electrical or mechanical compatibility.
