TR/PCD-5-R Equivalent & Substitute Parts

Part Overview

The TR/PCD-5-R is a board mount fuse manufactured by Eaton - Electronics Division, rated at 5A with 125V AC and 400V DC voltage ratings. This through-hole radial fuse is designed for fast-blow response applications and is currently in active production status with 1,483 pieces available in inventory. The PC-Tron® series component meets CSA and UL approval requirements and is ROHS3 compliant.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter ranges for this fuse category, considering current rating, voltage ratings, response time, package configuration, and approval certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TR/PCD-5-R is determined by the following criteria:

Current Rating: The substitute part must maintain the 5A current rating to ensure equivalent circuit protection.

Voltage Ratings: The substitute part must meet or exceed both the 125V AC and 400V DC voltage ratings. A substitute with higher voltage ratings (250V AC and 250V DC) satisfies this requirement as it provides equal or greater electrical stress capability.

Response Time: Fast-blow characteristic must be maintained for consistent overcurrent protection behavior.

Mounting Configuration: Through-hole radial package configuration must be preserved for board assembly compatibility.

Approval Certifications: The substitute must carry recognized regulatory approvals (CSA, UL, or equivalent cULus certification) to maintain compliance in the target application.

The Littelfuse 80815000000 meets all substitution criteria through equivalent current rating, superior voltage ratings, matching response time, identical mounting type, and valid regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - TR/PCD-5-R (Eaton): Select this part when the application specifically requires 400V DC voltage rating capability and Eaton component qualification is mandated. Current inventory of 1,483 pieces supports immediate availability. CSA and UL certifications confirm regulatory compliance for North American markets.

Substitute Part - 80815000000 (Littelfuse): This TE5® 808 series fuse is suitable for applications where the 400V DC requirement can be relaxed to 250V DC operation. The substitute provides superior breaking capacity (10kA DC versus 4.2kA DC) and extended operating temperature range (-40°C to 125°C). Higher inventory availability (2,705 pieces) and cULus certification provide equivalent regulatory standing. The Littelfuse part is appropriate for designs operating at or below 250V DC with 5A current requirements.

Selection Criteria: Choose the TR/PCD-5-R when 400V DC voltage rating is a circuit requirement. Choose the 80815000000 when 250V DC operation is acceptable and enhanced breaking capacity or temperature range is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 80815000000 replace the Eaton TR/PCD-5-R in all applications?

A: The Littelfuse substitute is compatible with applications operating at 250V DC or lower. If the circuit operates above 250V DC, the TR/PCD-5-R must be used to maintain voltage rating compliance.

Q: Are the physical dimensions identical between these two fuses?

A: Dimensions are nearly identical with negligible differences (length 0.350" for both; width 0.184" versus 0.183"; height 0.345" versus 0.350"). These variations are within standard manufacturing tolerances for through-hole radial board mount fuses and do not affect PCB footprint compatibility.

Q: Do both fuses carry the same regulatory approvals?

A: The TR/PCD-5-R carries CSA and UL certifications. The Littelfuse 80815000000 carries cULus certification, which provides equivalent regulatory coverage for North American applications. Both are ROHS3 compliant.

Q: What is the primary electrical difference between these fuses?

A: The main difference is voltage rating: TR/PCD-5-R supports 125V AC / 400V DC, while the Littelfuse supports 250V AC / 250V DC. Both maintain identical 5A current rating and fast-blow response time. The Littelfuse provides higher breaking capacity (10kA DC versus 4.2kA DC).

Q: Can I use the TR/PCD-5-R in a 250V DC circuit?

A: Yes. The TR/PCD-5-R is rated for 400V DC, which exceeds the 250V DC requirement. It is suitable for any application at or below its rated voltage.

Q: Which fuse should I select for new designs?

A: For new designs, specify the part that matches your circuit voltage requirements. If 250V DC operation is sufficient, the Littelfuse 80815000000 offers higher breaking capacity and extended temperature range. If 400V DC capability is required, specify the TR/PCD-5-R.
