Substitute Part Grouping Explanation

Substitution of the KLDR02.8T is based on strict equivalence across the following critical parameters:

  • Current Rating: 2.8A (exact match required)
  • Voltage Rating: 600 VAC / 300 VDC (exact match required)
  • Response Time: Slow Blow (exact match required)
  • Fuse Class: CC (exact match required)
  • Physical Package: 5AG, 10mm x 38mm Midget cartridge (exact match required)
  • Mounting Type: Requires Holder (exact match required)
  • Approval Certifications: CE, CSA, UL (minimum requirement)

The KLDR02.8TXP is a direct equivalent substitute manufactured by Littelfuse Inc. within the same POWR-GARD® KLDR series. This part maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Engineering Selection Recommendations

The KLDR02.8TXP is the appropriate substitute for the obsolete KLDR02.8T. Both parts maintain identical electrical performance specifications, mechanical dimensions, and regulatory certifications (CE, CSA, UL). The primary distinction is product status: the KLDR02.8TXP is actively manufactured and stocked, whereas the KLDR02.8T is obsolete. For new designs, maintenance applications, or system replacements, the KLDR02.8TXP should be specified. Both parts satisfy ROHS3 compliance requirements and are suitable for transformer protection applications requiring 2.8A protection at 600 VAC / 300 VDC.

Frequently Asked Questions (FAQ)

Q: Can the KLDR02.8TXP be used as a direct replacement for the KLDR02.8T?

A: Yes. The KLDR02.8TXP is a direct equivalent substitute. All electrical parameters (current rating, voltage ratings, response time, breaking capacity), mechanical dimensions, package type, and regulatory certifications are identical.

Q: What is the physical package size for both parts?

A: Both the KLDR02.8T and KLDR02.8TXP use the 5AG midget cartridge package, measuring 0.406" diameter by 1.500" length (10.30mm x 38.10mm). Both require a compatible fuse holder for installation.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical approval certifications (CE, CSA, UL) and are ROHS3 compliant. There are no compliance or certification differences.

Q: Why is the KLDR02.8T listed as obsolete?

A: The KLDR02.8T has been discontinued by the manufacturer. The KLDR02.8TXP represents the active production equivalent within the same series and should be used for all new procurement.

Q: What applications are these fuses designed for?

A: Both parts are specified for transformer protection in industrial and commercial electrical systems operating at 600 VAC or 300 VDC.
