Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0876002.MRET1SZP 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: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Melting I²t: 2.51 (exact match required)
• Physical Dimensions: 0.142" Dia x 0.394" L / 3.60mm x 10.00mm (exact match required)
• DC Cold Resistance: 0.0329 Ohms (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)

The primary distinction between the main part and its substitute is packaging format. The 0876002.MRET1SZP is supplied in standard packaging, while the substitute part 0876002.MRET1P is supplied in Cut Tape (CT) format. Both parts are manufactured by Littelfuse Inc. and belong to the 876 series.

Parameter Comparison

Engineering Selection Recommendations

Both the 0876002.MRET1SZP and 0876002.MRET1P are Active status products manufactured by Littelfuse Inc. and maintain full RoHS3 compliance. Selection between these parts should be based on packaging requirements and application assembly methodology:

• The 0876002.MRET1SZP is suitable for applications requiring standard packaging formats and supports a broader set of regulatory approvals (cURus, CQC, KC, PSE, VDE).
• The 0876002.MRET1P is suitable for high-volume automated assembly processes utilizing Cut Tape (CT) format and supports cULus and VDE approvals.

Both parts deliver identical electrical performance and mechanical compatibility within through-hole mounting applications. The choice between them is determined by supply chain availability, assembly equipment capability, and regulatory certification requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 0876002.MRET1P be used as a direct replacement for the 0876002.MRET1SZP?

A: Yes. Both parts are electrically and mechanically equivalent. The primary difference is packaging format (Cut Tape vs. standard packaging). Direct substitution is valid for through-hole mounting applications where the packaging format is compatible with assembly equipment.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires exact equivalence across current rating (2 A), voltage rating (250 VAC), fuse type (Cartridge, Ceramic), response time (Fast Blow), breaking capacity (35 A), melting I²t (2.51), physical dimensions (0.142" Dia x 0.394" L), DC cold resistance (0.0329 Ohms), operating temperature range (-55°C ~ 125°C), and mounting type (Through Hole).

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

A: Yes. The 0876002.MRET1SZP carries approvals from cURus, CQC, KC, PSE, and VDE. The 0876002.MRET1P carries approvals from cULus and VDE. Verify that the substitute part's approval set meets your application's regulatory requirements before implementation.

Q: What is the impact of packaging format on component selection?

A: Packaging format affects assembly methodology and supply chain logistics but does not impact electrical or mechanical performance. Cut Tape (CT) format is optimized for automated pick-and-place assembly, while standard packaging is suitable for manual or mixed assembly environments.

Q: Are both parts currently available?

A: Both parts maintain Active product status. The 0876002.MRET1SZP has 1056 pcs in stock, and the 0876002.MRET1P has 2628 pcs in stock. Inventory levels should be confirmed at the time of procurement.
