FMP300JR-73-100R Equivalent & Substitute Parts

Part Overview

The FMP300JR-73-100R is a 100 Ohms ±5% 3W through hole resistor manufactured by YAGEO in the FMP series. This metal film axial resistor features flame proof and safety characteristics, designed for applications requiring reliable power dissipation in the 3-watt range. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained while potentially offering improved specifications or alternative packaging formats.

Substitute Part Grouping Explanation

Substitution of the FMP300JR-73-100R is based on the following critical parameters that must remain constant or improve:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 3W (minimum requirement)
• Package type: Axial (mechanical compatibility)
• Physical dimensions: 0.197" Dia x 0.610" L (form factor compatibility)
• Operating temperature range: -55°C to 155°C (minimum coverage required)
• Composition: Metal Film (electrical performance class)
• Regulatory compliance: ROHS3 and REACH status maintained

The FMP300FTF73-100R qualifies as a substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±1% versus ±5%), providing enhanced precision for applications where tighter tolerance is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the FMP300JR-73-100R and FMP300FTF73-100R are active production parts from YAGEO with full ROHS3 compliance and REACH unaffected status. The primary distinction is tolerance specification: the main part offers ±5% tolerance with tape and reel packaging, while the substitute provides ±1% tolerance with cut tape packaging. Selection between these parts depends on circuit tolerance requirements and procurement format preferences. Both parts maintain identical electrical performance characteristics, thermal operating range, and mechanical form factor, ensuring direct functional compatibility in axial resistor applications rated for 3-watt power dissipation.

Frequently Asked Questions (FAQ)

Q: Can FMP300FTF73-100R directly replace FMP300JR-73-100R in existing designs?

A: Yes. Both parts share identical resistance value, power rating, physical dimensions, operating temperature range, and axial package type. The substitute offers improved tolerance specification (±1% versus ±5%), which is a performance enhancement rather than a limitation.

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging?

A: Tape and reel packaging provides continuous strip format suitable for automated assembly equipment with reel handling capability. Cut tape provides individual segments cut from the reel, suitable for manual assembly or equipment without reel feeders. Both formats contain the same component; packaging selection depends on assembly process requirements.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts maintain identical operating temperature range (-55°C to 155°C), power dissipation capability (3W), and metal film composition. The tolerance difference (±5% versus ±1%) affects precision but not thermal or electrical performance characteristics.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both FMP300JR-73-100R and FMP300FTF73-100R are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited), ensuring equivalent compliance status for regulated applications.

Q: Which part should be selected for new designs?

A: Selection is based on tolerance requirements and packaging format. For applications requiring tighter tolerance control, FMP300FTF73-100R (±1%) is appropriate. For standard tolerance applications, either part is suitable. Packaging format (tape and reel versus cut tape) should align with manufacturing process capabilities.
