Substitute Part Grouping Explanation

The Littelfuse 0230002.DRT1P qualifies as a parametric equivalent to the 0230002.DRT2P based on identical electrical and mechanical specifications. Both parts share the same current rating (2A), voltage ratings (250VAC/125VDC), fuse type (glass cartridge), response time (slow blow), physical dimensions (0.177" Dia x 0.571" L), breaking capacity, melting I²t value, operating temperature range, DC cold resistance, and regulatory approvals.

The substitution is valid across all critical parameters that determine functional compatibility. The only difference between these parts is the packaging format: the main part (0230002.DRT2P) is supplied in Tape & Reel (TR) configuration, while the substitute (0230002.DRT1P) is supplied in Cut Tape (CT) configuration. Both packaging types contain identical components suitable for automated or manual assembly processes.

Engineering Selection Recommendations

Both the 0230002.DRT2P and 0230002.DRT1P are Active status products from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and assembly process compatibility.

The 0230002.DRT2P in Tape & Reel (TR) packaging is suitable for high-volume automated assembly operations where continuous reel feeding is required. The 0230002.DRT1P in Cut Tape (CT) packaging is suitable for lower-volume production, manual assembly, or applications where individual component handling is preferred.

Both parts carry equivalent regulatory compliance certifications (CE, CSA, PSE, UL) and ROHS3 compliance status, ensuring equivalent environmental and safety standards. The choice between these substitutes does not affect circuit protection performance, thermal characteristics, or electrical performance in the application.

Frequently Asked Questions (FAQ)

Q: Can 0230002.DRT1P be used as a direct replacement for 0230002.DRT2P in circuit applications?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (2A, 250VAC/125VDC), fuse characteristics (slow blow, glass cartridge), physical dimensions, breaking capacity, and thermal specifications. The only difference is packaging format (Cut Tape vs. Tape & Reel).

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape packaging supplies components on tape segments, typically used for manual assembly, lower-volume production, or component kitting. The fuse components themselves are identical.

Q: Are there any compatibility issues when switching between these two part numbers?

A: No compatibility issues exist from an electrical or mechanical standpoint. Both parts have identical dimensions (0.177" Dia x 0.571" L), mounting type (through hole), and electrical characteristics. Assembly process compatibility depends on whether your production equipment supports the specific packaging format.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both 0230002.DRT2P and 0230002.DRT1P carry identical approvals (CE, CSA, PSE, UL) and ROHS3 compliance status, ensuring equivalent regulatory compliance for your application.

Q: What factors should determine which part to select?

A: Selection should be based on your assembly process requirements. Choose Tape & Reel (0230002.DRT2P) for automated high-volume production. Choose Cut Tape (0230002.DRT1P) for manual assembly, lower volumes, or component kitting applications. Electrical performance and circuit protection characteristics are identical between both options.
