Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5VTP 3.15-R are qualified based on the following critical parameters that must match or remain within acceptable tolerances:

• Current Rating: 3.15 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The following parts meet these substitution criteria:

• 02133.15MXEP (Littelfuse Inc., Series 213) — Direct substitute
• 02183.15MXEP (Littelfuse Inc., Series 218) — Direct substitute

Parameter Comparison

Engineering Selection Recommendations

Both 02133.15MXEP and 02183.15MXEP are active products from Littelfuse Inc. and serve as direct substitutes for the obsolete 5VTP 3.15-R. Selection between these two options should be based on:

• Availability: 02183.15MXEP has higher inventory (3185 pcs) compared to 02133.15MXEP (2599 pcs)
• Compliance certifications: 02183.15MXEP includes K-MARK and UL approvals in addition to CCC, CE, CSA, PSE, SEMKO, and VDE; 02133.15MXEP includes BSI and UR approvals
• DC Cold Resistance: 02183.15MXEP exhibits lower resistance (0.0173 Ohms) versus 02133.15MXEP (0.0231 Ohms)

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with modern component sourcing requirements.

Frequently Asked Questions (FAQ)

Q: Can 02133.15MXEP and 02183.15MXEP be used interchangeably with 5VTP 3.15-R?

A: Yes. Both parts match the critical electrical and mechanical parameters: 3.15 A current rating, 250 V AC voltage rating, slow-blow response, 5mm x 20mm package, 35 A breaking capacity, and -55°C to 125°C operating temperature range.

Q: What is the difference between 02133.15MXEP and 02183.15MXEP?

A: The primary differences are melting I²t (202 vs. 38.15), DC cold resistance (0.0231 vs. 0.0173 Ohms), and certification scope. Both are functionally equivalent for the specified electrical ratings and package dimensions.

Q: Are these substitute parts available in the same packaging as the original?

A: The substitute parts are supplied in bulk packaging, whereas the original 5VTP 3.15-R packaging type is not specified. Verify packaging requirements for your application before procurement.

Q: Do the substitute parts meet the same compliance standards?

A: Both substitute parts are ROHS3 compliant and REACH unaffected. Certification agencies include CCC, CE, CSA, SEMKO, and VDE for both parts, with additional certifications available on 02183.15MXEP (K-MARK, UL) and 02133.15MXEP (BSI, UR, PSE).

Q: What is the moisture sensitivity level (MSL) of the substitute parts?

A: Both substitute parts have MSL listed as Not Applicable, indicating no moisture sensitivity constraints during storage or handling.
