Substitute Part Grouping Explanation

The RSMF2JB8R20 and RSMF2JT8R20 are direct substitutes based on identical electrical and mechanical parameters. Both parts share the same resistance value, tolerance, power rating, composition, physical dimensions, and operating characteristics. The substitution is valid across the following key parameters:

• Resistance: 8.2 Ohms
• Tolerance: ±5%
• Power Rating: 2W
• Composition: Metal Oxide Film
• Package / Case: Axial
• Physical Dimensions: 0.177" Dia x 0.433" L (4.50mm x 11.00mm)
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C ~ 235°C
• Features: Flame Proof, Safety
• RoHS Compliance: ROHS3 Compliant

The only difference between these parts is packaging format: RSMF2JB8R20 is supplied in Bulk packaging, while RSMF2JT8R20 is supplied in Cut Tape (CT) packaging.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB8R20 and RSMF2JT8R20 are suitable for applications requiring 8.2 Ohms ±5% 2W axial resistors with metal oxide film construction. Selection between these parts should be based on packaging requirements and inventory availability:

• RSMF2JB8R20 (Bulk packaging) is appropriate for high-volume manual assembly or reel-fed automated processes where bulk quantities are preferred.
• RSMF2JT8R20 (Cut Tape packaging) is appropriate for automated pick-and-place assembly systems and applications requiring tape-and-reel format.

Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance (ROHS3 Compliant, REACH Unaffected). Selection does not impact circuit functionality or reliability.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT8R20 be used as a direct replacement for RSMF2JB8R20?
