AGRF800-2 Polymeric PTC Resettable Fuse Equivalent & Substitute Parts

Part Overview

The AGRF800-2 is a polymeric PTC resettable fuse manufactured by Littelfuse, rated for 16V maximum voltage with 8A hold current. This component is designed for overcurrent protection in electronic circuits and automatically resets after a fault condition is cleared. The part is currently in active production status with 1541 units in stock. Equivalent and substitute parts are identified to provide procurement flexibility, ensure supply chain continuity, and support design alternatives when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AGRF800-2 is determined by the following critical parameters:

• Voltage rating must equal or exceed 16V maximum
• Current hold (Ih) rating must equal 8A
• Mounting type must be Through Hole
• Package configuration must be Radial, Disc
• Physical dimensions must be compatible with 0.500" L x 0.118" W footprint
• Operating temperature range must encompass -40°C ~ 85°C
• Type must be Polymeric PTC resettable fuse

The substitute part 16R800GF meets all substitution criteria. Both parts are manufactured by Littelfuse, share identical voltage and hold current ratings, use the same mounting and package type, and operate within the same temperature range. Minor variations in current trip (It) values and resistance characteristics fall within acceptable tolerance for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the AGRF800-2 and 16R800GF are active production parts from Littelfuse with full ROHS3 compliance and REACH unaffected status. The 16R800GF carries additional third-party approvals (cURus, TUV) which may be required for specific applications. The primary distinction between these parts is packaging format: AGRF800-2 is supplied in Cut Tape configuration, while 16R800GF is supplied in Bulk packaging. Selection between these parts should be based on procurement requirements, packaging preferences, and any application-specific certification mandates. Both parts are electrically and mechanically compatible for direct substitution in circuits designed for 16V, 8A polymeric PTC resettable fuse protection.

Frequently Asked Questions (FAQ)

Q: Can the 16R800GF directly replace the AGRF800-2 in my circuit?

A: Yes. Both parts share identical voltage ratings (16V), hold current ratings (8A), mounting type (Through Hole), and package configuration (Radial, Disc). The physical dimensions and operating temperature ranges are equivalent, making them direct electrical and mechanical substitutes.

Q: What is the difference between the Current - Trip (It) values?

A: The AGRF800-2 has a trip current of 15A, while the 16R800GF has a trip current of 13.6A. Both values fall within the acceptable operating range for this component category. The difference reflects normal manufacturing variation between product series. Selection should be based on your specific overcurrent protection threshold requirements.

Q: Does packaging format affect electrical performance?

A: No. The Cut Tape (CT) packaging of the AGRF800-2 and Bulk packaging of the 16R800GF do not affect electrical characteristics or performance. Packaging format is a procurement and handling consideration only.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The 16R800GF carries additional third-party certifications (cURus, TUV). If your application requires specific regulatory approvals, the 16R800GF may be the preferred choice.

Q: What is the moisture sensitivity level for these parts?

A: The AGRF800-2 has no applicable moisture sensitivity level (Not Applicable). The 16R800GF is rated MSL 1 (Unlimited), indicating minimal moisture sensitivity. Both parts are suitable for standard storage and handling conditions.
