Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JB6K80 is determined by the following critical parameters:

• Resistance value: 6.8 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 235°C (exact match required)
• Package type: Axial (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Substitute parts may differ in power rating (2W or higher), physical dimensions, packaging format (Bulk, Cut Tape, or Tape & Reel), and surface treatment specifications (flame retardant vs. flame proof), provided all electrical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

RSMF3JT6K80 provides a power rating upgrade to 3W while maintaining identical electrical specifications and physical dimensions. This part is suitable for applications requiring enhanced thermal margin or higher dissipation capacity.

RSMF2JT6K80 maintains the 2W power rating with reduced physical dimensions (4.50mm x 11.00mm versus 5.50mm x 15.00mm). This part is suitable for space-constrained applications where the smaller form factor is compatible with circuit board layout requirements.

All substitute parts are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT6K80 replace RSF2JB6K80 in any application?

A: RSMF3JT6K80 is electrically equivalent with identical resistance, tolerance, temperature coefficient, and operating range. The 3W power rating is a superset of the 2W requirement. Physical dimensions are identical. Substitution is valid provided circuit board layout accommodates the part.

Q: What is the primary difference between RSMF2JT6K80 and RSF2JB6K80?

A: Both parts share identical electrical specifications and 2W power rating. RSMF2JT6K80 has reduced physical dimensions (4.50mm x 11.00mm versus 5.50mm x 15.00mm). Substitution requires verification that the smaller form factor fits the circuit board layout and component spacing.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: All three parts use axial package type with identical lead termination count (2). Dimensional differences exist only for RSMF2JT6K80. Circuit board hole spacing and component clearance must accommodate the selected part's physical dimensions.

Q: Do packaging format differences affect electrical performance?

A: No. Bulk, Cut Tape, and Tape & Reel formats are supply chain variations only. Electrical performance and reliability are identical across all packaging formats for the same part number.

Q: Which substitute part should be selected for high-reliability applications?

A: All three parts are active products with ROHS3 compliance and identical regulatory status. Selection should be based on power dissipation requirements, physical space constraints, and packaging format availability for your supply chain.
