TRS1R Equivalent & Substitute Parts

Part Overview

The TRS1R is a 600V 1A fuse manufactured by Mersen USA Newburyport-MA L.L.C., designed for electrical protection in industrial applications. This component is currently active in production and available in box packaging. Finding equivalent substitute parts is necessary when the primary part is unavailable, when bulk packaging is preferred, or when alternative certifications are required for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TRS1R is determined by the following critical electrical and mechanical parameters:

• Current Rating: 1A (exact match required)
• Voltage Rating - AC: 600V (exact match required)
• Fuse Type: Time Delay (slow blow response)
• Physical Form Factor: Cartridge fuse compatible with standard holders
• Approval Certifications: UL, CSA, or equivalent industrial standards

The FRS-R-1 qualifies as a substitute based on matching current rating (1A), AC voltage rating (600VAC), time delay response characteristic (Slow Blow), and cartridge form factor. Both parts are approved for industrial and electrical applications and maintain compatibility with standard fuse holder installations.

Parameter Comparison

Engineering Selection Recommendations

Both the TRS1R and FRS-R-1 are active products suitable for industrial and electrical applications. The FRS-R-1 offers additional advantages including RoHS compliance, documented breaking capacity ratings (200kA AC, 20kA DC), and explicit approval certifications (CE, CSA, UL). The TRS1R is RoHS non-compliant, which may restrict its use in applications requiring environmental compliance standards.

Selection between these parts should be based on application-specific compliance requirements. If RoHS compliance is mandatory, the FRS-R-1 is the appropriate choice. If RoHS non-compliance is acceptable and box packaging is preferred, the TRS1R remains viable. Both parts maintain identical electrical performance at 1A, 600VAC operation.

Frequently Asked Questions (FAQ)

Q: Can the FRS-R-1 directly replace the TRS1R? A: Yes, the FRS-R-1 is electrically and mechanically compatible as a substitute. Both are 1A, 600VAC cartridge fuses with time delay response characteristics. Installation requires a standard cartridge fuse holder.

Q: What is the difference in packaging between these parts? A: The TRS1R is supplied in box packaging, while the FRS-R-1 is supplied in bulk packaging. Bulk packaging is typically used for higher-volume applications or when individual unit packaging is not required.

Q: Does the FRS-R-1 provide DC voltage protection? A: Yes, the FRS-R-1 is rated for 300VDC operation in addition to 600VAC. The TRS1R specifications do not include a DC voltage rating. If DC protection is required, the FRS-R-1 offers this additional capability.

Q: What is the significance of RoHS compliance difference? A: The FRS-R-1 is RoHS compliant, meaning it meets Restriction of Hazardous Substances regulations. The TRS1R is RoHS non-compliant. Applications subject to environmental or regulatory restrictions may require the RoHS-compliant FRS-R-1.

Q: Are both parts approved for industrial use? A: Yes, both parts are active products approved for industrial and electrical applications. The FRS-R-1 carries explicit CE, CSA, and UL certifications, while the TRS1R approval certifications are not specified in available documentation.
