Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB9R10 is determined by strict equivalence across the following critical parameters:

• Resistance value: 9.1 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package type: Axial
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.177" Dia x 0.433" L (4.50mm x 11.00mm)
• Features: Flame Proof, Safety
• Manufacturer: Stackpole Electronics Inc
• Series: RSMF

The identified substitute part differs only in packaging format (Cut Tape vs. Bulk), which does not affect electrical or mechanical performance. All other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB9R10 and RSMF2JT9R10 are electrically and mechanically identical. Selection between these parts is determined solely by packaging and supply requirements:

• RSMF2JB9R10 (Bulk packaging) is suitable for high-volume applications or when bulk quantities are preferred for assembly operations.
• RSMF2JT9R10 (Cut Tape packaging) is suitable for automated pick-and-place assembly or when smaller quantities per reel are required.

Both parts maintain ROHS3 compliance and are rated for the same operating temperature range (-55°C to 235°C). The flame-proof and safety features are identical across both variants.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT9R10 be used as a direct replacement for RSMF2JB9R10?

A: Yes. The parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape vs. Bulk). Electrical performance, thermal characteristics, and physical dimensions are equivalent.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Bulk or Cut Tape) does not affect electrical performance, tolerance, power rating, or operating temperature range. The resistor element and specifications are identical.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the same temperature range of -55°C to 235°C with a temperature coefficient of ±200ppm/°C.

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

A: Bulk packaging provides loose components suitable for manual assembly or high-volume bin storage. Cut Tape packaging provides components on adhesive tape in specified quantities, optimized for automated assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both RSMF2JB9R10 and RSMF2JT9R10 are ROHS3 compliant.
