Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB6K20 is determined by the following critical parameters:

• Resistance value: 6.2 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 235°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The RSF2JT6K20 qualifies as a direct substitute, maintaining all critical electrical parameters and compliance certifications. Physical dimensions vary due to different flame-protective coating specifications (flame-proof versus flame-retardant coating), but both parts function identically within the specified electrical and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB6K20 and RSF2JT6K20 maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts should be based on:

• Packaging format requirements: RSMF2JB6K20 is supplied in bulk packaging; RSF2JT6K20 is supplied in cut tape format
• Physical space constraints: RSMF2JB6K20 has smaller axial dimensions (4.50mm diameter); RSF2JT6K20 has larger dimensions (5.50mm diameter)
• Inventory availability: RSF2JT6K20 currently has higher stock levels (1980 units versus 952 units)
• Flame protection specification: RSMF2JB6K20 features flame-proof construction; RSF2JT6K20 features flame-retardant coating

Both parts deliver identical electrical performance across the full operating temperature range and maintain equivalent safety certifications.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT6K20 be used as a direct replacement for RSMF2JB6K20 in all applications?

A: Yes. Both parts share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The primary differences are physical dimensions and packaging format. Verify that the larger axial dimensions of RSF2JT6K20 (5.50mm diameter versus 4.50mm) accommodate your PCB layout constraints.

Q: What is the difference between flame-proof and flame-retardant coating?

A: Both designations indicate fire safety features. Flame-proof construction (RSMF2JB6K20) and flame-retardant coating (RSF2JT6K20) both meet safety standards for this product category. Selection depends on specific application safety requirements and regulatory compliance needs.

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

A: No. Both parts maintain identical electrical specifications: 6.2 kOhms resistance, ±5% tolerance, 2W power rating, ±200ppm/°C temperature coefficient, and -55°C to 235°C operating range.

Q: Which packaging format should I select?

A: RSMF2JB6K20 bulk packaging suits high-volume manual assembly or bin storage. RSF2JT6K20 cut tape format is optimized for automated pick-and-place assembly equipment. Choose based on your manufacturing process requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both RSMF2JB6K20 and RSF2JT6K20 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
