Parameter Comparison

Engineering Selection Recommendations

Both the 023004.6DRT2P and 023004.6DRT1P maintain Active product status and carry identical electrical, mechanical, and compliance certifications. Selection between these parts is determined by packaging and supply requirements:

023004.6DRT2P (Tape & Reel): Suitable for high-volume automated assembly operations requiring continuous reel-fed component dispensing.

023004.6DRT1P (Cut Tape): Suitable for lower-volume applications, manual assembly, or procurement scenarios where cut tape packaging is preferred.

Both parts satisfy CE, CSA, PSE, and UL approval requirements and maintain ROHS3 compliance. No electrical or mechanical performance differentiation exists between these variants.

Frequently Asked Questions (FAQ)

Q: Can 023004.6DRT1P be used as a direct replacement for 023004.6DRT2P in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The 4.6 A current rating, 250 V AC / 125 V DC voltage specifications, slow-blow response time, and all performance parameters are identical. Substitution is valid for any application using the main part number.

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 or lower-volume production. Both contain identical components; packaging format differs only.

Q: Are the physical dimensions identical between these two part numbers?

A: Yes. Both parts measure 0.177" Dia x 0.571" L (4.50mm x 14.50mm). Through-hole mounting compatibility is identical.

Q: Do both parts carry the same regulatory certifications?

A: Yes. Both 023004.6DRT2P and 023004.6DRT1P carry CE, CSA, PSE, and UL approvals and are ROHS3 compliant. Operating temperature range is -55°C ~ 125°C for both variants.

Q: Which part should be selected for automated assembly?

A: The 023004.6DRT2P (Tape & Reel) is optimized for automated assembly processes. The 023004.6DRT1P (Cut Tape) is suitable for manual assembly or lower-volume applications.
