Key Parameters

Substitute Part Grouping Explanation

Substitution of the KLDR.200T is determined by strict equivalence across the following critical parameters:

• Current Rating: 200mA (exact match required)
• Voltage Rating: 600 VAC / 300 VDC (exact match required)
• Fuse Class: CC (exact match required)
• Response Time: Slow Blow (exact match required)
• Physical Package: 5AG, 10mm x 38mm Midget cartridge (exact match required)
• Mounting Type: Requires Holder (exact match required)

The KLDR.200TXP meets all substitution criteria as a direct equivalent within the same POWR-GARD® KLDR series, maintaining identical electrical and mechanical specifications while offering improved product availability due to Active status.

Parameter Comparison

Engineering Selection Recommendations

The KLDR.200TXP is the direct substitute for the KLDR.200T. Both components carry identical electrical ratings, mechanical specifications, and regulatory certifications (CE, CSA, UL). The primary distinction is product status: KLDR.200T is Obsolete while KLDR.200TXP maintains Active status, ensuring continued availability and supply chain reliability. Selection of KLDR.200TXP is appropriate for all applications previously served by KLDR.200T, with no circuit redesign or holder modification required.

Frequently Asked Questions (FAQ)

Q: Can KLDR.200TXP be used as a direct replacement for KLDR.200T?

A: Yes. Both components are identical in current rating (200mA), voltage rating (600 VAC / 300 VDC), fuse class (CC), response time (Slow Blow), and physical dimensions (5AG, 10mm x 38mm). No circuit modifications are necessary.

Q: What is the significance of the Obsolete status for KLDR.200T?

A: Obsolete status indicates that the manufacturer has discontinued production. KLDR.200TXP, with Active status, ensures ongoing availability and is the recommended procurement choice for new installations and replacements.

Q: Are the regulatory certifications identical between these parts?

A: Yes. Both KLDR.200T and KLDR.200TXP carry CE, CSA, and UL approvals, maintaining compliance with applicable standards.

Q: Does the packaging difference affect compatibility?

A: No. KLDR.200T is supplied without specified packaging, while KLDR.200TXP is supplied in Box packaging. Both components are identical 5AG cartridge fuses requiring the same holder. Packaging affects logistics only, not electrical or mechanical function.

Q: What holder type is required for these fuses?

A: Both KLDR.200T and KLDR.200TXP require a compatible 5AG cartridge fuse holder rated for 600 VAC / 300 VDC operation. The fuses are not standalone components and must be installed in an appropriate holder assembly.
