Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0RLN005.T is determined by the following critical parameters:

• Current Rating: Must be 5A to maintain circuit protection design intent
• Voltage Rating (AC): Must support minimum 250 VAC operation
• Physical Dimensions: Must be 0.563" Dia x 2.000" L to fit existing cartridge holders
• Response Time: Fast-blow characteristic must be maintained for application compatibility
• Fuse Type: Must be cartridge format requiring holder mounting
• Approval Certifications: Must maintain CE, CSA, and UL compliance for regulatory continuity

The KLNR005.T meets all these criteria while offering enhanced specifications including DC voltage capability and improved breaking capacity, making it a direct substitute for the obsolete 0RLN005.T.

Parameter Comparison

Engineering Selection Recommendations

The KLNR005.T is the qualified substitute for the 0RLN005.T based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical current rating (5A) and AC voltage rating (250 VAC), ensuring circuit protection characteristics remain unchanged. The KLNR005.T adds 125 VDC capability, expanding application flexibility without compromising AC performance.

Physical Compatibility: Identical cartridge dimensions (0.563" Dia x 2.000" L) ensure direct mechanical fit in existing fuse holders without modification.

Regulatory Compliance: Both parts carry CE, CSA, and UL certifications, maintaining compliance requirements. The KLNR005.T achieves ROHS3 compliance, meeting current environmental standards where the obsolete 0RLN005.T does not.

Performance Enhancement: The KLNR005.T provides significantly higher breaking capacity (200kA AC versus 10kA), offering superior fault protection margins in industrial applications.

Availability: The KLNR005.T is active production status with current inventory, ensuring long-term supply continuity compared to the obsolete 0RLN005.T.

Frequently Asked Questions (FAQ)

Q: Can the KLNR005.T be used as a direct replacement in all 0RLN005.T applications?

A: Yes. The KLNR005.T maintains identical current rating, AC voltage rating, response time, and physical dimensions. It fits existing cartridge holders without modification and carries the same regulatory certifications.

Q: What is the difference between Class H and Class RK1 fuses?

A: Class designation indicates fuse performance characteristics and breaking capacity. The KLNR005.T (Class RK1) provides higher breaking capacity (200kA AC) compared to the 0RLN005.T (Class H, 10kA), offering enhanced protection in high-fault-current environments.

Q: Does the KLNR005.T's DC voltage rating affect AC-only applications?

A: No. The addition of 125 VDC capability does not impact AC circuit operation. The 250 VAC rating remains the controlling specification for AC applications.

Q: Are there inventory considerations when switching from 0RLN005.T to KLNR005.T?

A: The KLNR005.T is in active production with 860 units currently in stock, compared to the obsolete 0RLN005.T with limited remaining inventory. Transition to KLNR005.T ensures supply continuity.

Q: Does the KLNR005.T meet current environmental compliance requirements?

A: Yes. The KLNR005.T is ROHS3 compliant and REACH unaffected, meeting current environmental standards. The obsolete 0RLN005.T is RoHS non-compliant.
