Equivalent & Substitute Parts for TR/PCB-2-R

Part Overview

The TR/PCB-2-R is a 2 A, 250 V AC / 450 V DC board mount fuse manufactured by Eaton - Electronics Division under the PC-Tron® series. This through-hole radial fuse is designed for fast-blow response applications requiring board-level protection in industrial and commercial electronic equipment. The part maintains active product status with 4160 units in current inventory. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design flexibility is required within equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TR/PCB-2-R is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Current Rating: 2 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 450 V (exact match required)
• Response Time: Fast Blow (exact match required)

Mechanical Equivalence Requirements:

• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: Radial, Box (exact match required)

Compliance Requirements:

• RoHS3 Compliant status (required for environmental compatibility)
• Active product status (required for ongoing availability)

The substitute part 80812000000 (Littelfuse TE5® 808 series) meets all mandatory equivalence criteria and qualifies as a direct substitute for the TR/PCB-2-R.

Parameter Comparison

Engineering Selection Recommendations

Both the TR/PCB-2-R and 80812000000 are active products with current manufacturing status and full RoHS3 compliance. The TR/PCB-2-R carries CSA and UL approvals, while the 80812000000 carries cULus certification. Both certifications are recognized standards for board-mounted fuse applications.

The TR/PCB-2-R should be selected as the primary component when Eaton sourcing is preferred or when CSA/UL certification specifically is required by design specification. The 80812000000 serves as a qualified substitute when Littelfuse sourcing is preferred, when cULus certification meets application requirements, or when the higher breaking capacity ratings (100 A AC, 10 kA DC versus 50 A AC, 5.9 kA DC) provide additional design margin.

Physical dimensions are equivalent within manufacturing tolerance, with both parts measuring approximately 0.350" length and fitting standard through-hole radial fuse footprints. Both parts are supplied in cut-tape packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 80812000000 be used as a direct replacement for the TR/PCB-2-R in existing designs?

A: Yes. Both parts share identical electrical ratings (2 A, 250 V AC, 450 V DC, Fast Blow response), identical mounting type (through-hole), identical fuse type (board mount, cartridge style excluded), and identical package configuration (radial, box). Physical dimensions are equivalent within standard manufacturing tolerances. Both are RoHS3 compliant and carry active product status.

Q: What is the difference in breaking capacity between these two parts?

A: The TR/PCB-2-R has a breaking capacity of 50 A AC and 5.9 kA DC at rated voltage. The 80812000000 has a breaking capacity of 100 A AC and 10 kA DC at rated voltage. Both exceed standard requirements for 2 A fuse applications. The higher breaking capacity of the 80812000000 provides additional safety margin in high-fault-current environments.

Q: Are the certifications equivalent?

A: The TR/PCB-2-R carries CSA and UL approvals. The 80812000000 carries cULus certification. Both are recognized standards for board-mounted fuse applications. Verify that your specific application requirements accept cULus certification if substituting from CSA/UL to cULus.

Q: Do these parts fit the same PCB footprint?

A: Yes. Both parts are through-hole radial fuses with dimensions of approximately 0.350" length and 0.184-0.183" width. Footprint compatibility is confirmed for standard radial fuse land patterns.

Q: What is the packaging format for both parts?

A: Both the TR/PCB-2-R and 80812000000 are supplied in cut-tape (CT) packaging, suitable for automated pick-and-place assembly equipment.

Q: Which part should I specify for new designs?

A: Either part is acceptable for new designs provided that the selected manufacturer's certification (CSA/UL for Eaton or cULus for Littelfuse) meets your application requirements. Consider supply chain availability and lead time when making the selection.
