Key Parameters

Substitute Part Grouping Explanation

Substitution of the KLDR002.T is determined by strict equivalence across electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

• Current Rating: 2A
• Voltage Rating: 600 VAC / 300 VDC
• Fuse Class: CC
• Response Time: Slow Blow
• Physical Package: 5AG, 10mm x 38mm (Midget)
• Breaking Capacity: 200kA AC, 20kA DC
• Mounting Type: Requires Holder

The KLDR002.TXP meets all these requirements and is classified as an active product, making it a direct functional equivalent for the obsolete KLDR002.T.

Parameter Comparison

Engineering Selection Recommendations

The KLDR002.TXP is the direct equivalent for the obsolete KLDR002.T. Both components share identical electrical ratings, mechanical dimensions, and regulatory certifications. The KLDR002.TXP maintains active product status with Littelfuse Inc., ensuring ongoing availability and supply chain continuity. Selection of the KLDR002.TXP eliminates obsolescence risk while preserving all functional and compliance characteristics required for transformer protection applications in 600 VAC / 300 VDC systems.

Frequently Asked Questions (FAQ)

Q: Can the KLDR002.TXP be used as a direct replacement for the KLDR002.T?

A: Yes. Both components are identical in electrical specifications (2A, 600 VAC / 300 VDC), fuse class (CC), response time (Slow Blow), physical dimensions (10mm x 38mm), and breaking capacity (200kA AC, 20kA DC). The KLDR002.TXP is the active equivalent.

Q: What is the difference between KLDR002.T and KLDR002.TXP?

A: The primary difference is product status. KLDR002.T is obsolete, while KLDR002.TXP is active. Packaging differs (KLDR002.T uses standard packaging; KLDR002.TXP uses box packaging), but electrical and mechanical specifications are identical.

Q: Are both parts compatible with the same fuse holder?

A: Yes. Both components use the 5AG, 10mm x 38mm (Midget) package format and require a compatible cartridge fuse holder. Physical dimensions are identical at 0.406" Dia x 1.500" L (10.30mm x 38.10mm).

Q: Do both parts meet the same regulatory certifications?

A: Yes. Both KLDR002.T and KLDR002.TXP carry CE, CSA, and UL approvals and are ROHS3 compliant.

Q: Why should I transition from KLDR002.T to KLDR002.TXP?

A: The KLDR002.T is obsolete and subject to supply discontinuation. The KLDR002.TXP maintains identical functionality while ensuring long-term availability and supply chain reliability.
