Key Parameters

Substitute Part Grouping Explanation

Substitution for the TR2/C515-2-R is determined by the following critical parameters:

Primary Substitution Criteria:

• Current Rating: 2 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)

Secondary Compatibility Factors:

• Physical dimensions must accommodate through-hole mounting
• Approval agencies must include CSA and/or UL certification
• RoHS compliance status must be maintained

The identified substitute parts 0230002.DRT1P and 0230002.MXP, both manufactured by Littelfuse Inc., meet all primary substitution criteria. Both parts are rated 2A at 250VAC, feature slow-blow glass cartridge construction, and support through-hole mounting. The primary difference between these substitutes and the main part is the physical package size and DC voltage rating capability. The substitute parts are available in different packaging formats (Cut Tape and Bulk) compared to the main part's Tape & Reel packaging.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TR2/C515-2-R remains the preferred choice when Tape & Reel packaging is required for automated assembly processes. This part carries active product status and meets CSA and UL certifications.

Substitute Part Selection:

0230002.DRT1P (Littelfuse Inc.) is suitable for applications requiring Cut Tape packaging. This part is certified by CE, CSA, PSE, and UL, providing broader international compliance coverage than the primary part. The operating temperature range of -55°C to 125°C extends the usable envelope compared to the primary part. This option is appropriate for moderate-volume production runs or applications with specific temperature requirements.

0230002.MXP (Littelfuse Inc.) is suitable for high-volume applications or bulk procurement scenarios. This part offers the same electrical and functional specifications as 0230002.DRT1P but in bulk packaging format. With 34,412 units in stock, this part provides superior availability for large-scale deployments. The extended certifications (CE, CSA, PSE, UL) and ROHS3 compliance support global distribution requirements.

Physical Dimension Consideration: Both Littelfuse substitutes feature slightly smaller physical dimensions (4.50mm diameter vs. 5.50mm diameter for the primary part). PCB footprint compatibility must be verified before selection, as the reduced diameter may affect mechanical fit in existing through-hole mounting positions.

Breaking Capacity Difference: The primary part specifies 100A breaking capacity at rated voltage, while both substitutes specify 35A AC breaking capacity. This difference must be evaluated against circuit protection requirements.

Frequently Asked Questions (FAQ)

Q: Can 0230002.DRT1P and 0230002.MXP be used interchangeably with TR2/C515-2-R?

A: Both Littelfuse parts meet the core electrical specifications (2A, 250VAC, slow-blow, glass cartridge, through-hole mounting). However, physical dimension differences (4.50mm vs. 5.50mm diameter) require verification of PCB footprint compatibility. The breaking capacity difference (35A vs. 100A) must also be evaluated against circuit requirements.

Q: What is the difference between 0230002.DRT1P and 0230002.MXP?

A: Both parts are electrically and functionally identical. The primary difference is packaging format: 0230002.DRT1P is supplied in Cut Tape format suitable for moderate-volume assembly, while 0230002.MXP is supplied in Bulk format for high-volume procurement. Inventory availability also differs significantly (3,962 units vs. 34,412 units).

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 0230002.DRT1P and 0230002.MXP carry ROHS3 compliance status. The primary part TR2/C515-2-R is RoHS Compliant. Both meet current RoHS requirements.

Q: What certifications do the substitute parts carry?

A: Both Littelfuse substitutes carry CE, CSA, PSE, and UL certifications. The primary part carries CSA and UL certifications. The additional CE and PSE certifications on the substitutes provide broader international compliance coverage.

Q: Does the DC voltage rating on the substitute parts affect AC-only applications?

A: No. For AC-only applications, the DC voltage rating of the substitute parts is not a limiting factor. The 250VAC rating is the controlling specification for AC circuit protection. The 125VDC rating on the substitutes provides additional capability for dual-voltage applications.

Q: What is the operating temperature range for each part?

A: The primary part TR2/C515-2-R does not specify an operating temperature range. Both substitute parts specify -55°C to 125°C operating temperature range, providing defined thermal performance boundaries for temperature-sensitive applications.

Q: How do the DC cold resistance values compare?

A: The primary part specifies 0.059 Ohms DC cold resistance, while both substitutes specify 0.0698 Ohms. This 18% difference is within typical tolerance ranges for fuse cartridges and does not affect functional performance in standard circuit protection applications.
