FMP300JR-73-1R Equivalent & Substitute Parts

Part Overview

The FMP300JR-73-1R is a 1 Ohm, ±5% tolerance, 3W through-hole axial resistor manufactured by YAGEO in the FMP series. This metal film resistor features flame-proof and safety construction, designed for applications requiring reliable power dissipation in compact form factors. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FMP300JR-73-1R is determined by the following critical parameters:

• Resistance value: 1 Ohms (exact match required)
• Power rating: 3W (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.197" Dia x 0.610" L (exact match required)
• Composition: Metal Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (must encompass or equal)
• RoHS compliance: ROHS3 Compliant (must maintain or exceed)

The FMP300FRF73-1R qualifies as a substitute because it maintains identical resistance, power rating, package type, physical dimensions, composition, operating temperature range, and RoHS compliance status. The tolerance specification differs (±1% versus ±5%), representing an upgrade in precision rather than a limitation.

Parameter Comparison

Engineering Selection Recommendations

Both the FMP300JR-73-1R and FMP300FRF73-1R maintain active product status with full ROHS3 compliance and REACH unaffected certification. The FMP300FRF73-1R offers improved tolerance specification (±1% versus ±5%), which provides tighter resistance accuracy without compromising any electrical or mechanical parameters. Selection between these parts depends on application-specific tolerance requirements and packaging format availability. The main part is supplied in Tape & Reel format, while the substitute is available in Cut Tape format.

Frequently Asked Questions (FAQ)

Q: Can FMP300FRF73-1R replace FMP300JR-73-1R in all applications?

A: Yes, provided the application does not require the specific packaging format of the original part. The FMP300FRF73-1R is electrically and mechanically equivalent with superior tolerance specification.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or smaller volume applications. Both formats contain identical components.

Q: Does the ±1% tolerance of FMP300FRF73-1R affect compatibility?

A: No. Tighter tolerance represents improved precision and is compatible with all applications designed for the ±5% tolerance specification.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across -55°C to 155°C, maintaining identical thermal performance characteristics.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0090.
