Substitute Part Grouping Explanation

The KAL10JB1K00 can be substituted with the KAL10FB1K00 based on the following substitution criteria:

Identical Parameters (No Compromise):

• Resistance value: 1 kOhms
• Power rating: 12.5W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 275°C
• Housing type: Aluminum
• Mounting feature: Flanges
• Physical dimensions: 0.750" L x 0.800" W (19.05mm x 20.32mm)
• Height - Seated (Max): 0.421" (10.70mm)
• Lead style: Solder Lugs
• RoHS compliance: ROHS3 Compliant

Relaxed Parameter (Tolerance Enhancement):

• Tolerance: KAL10JB1K00 specifies ±5%, while KAL10FB1K00 provides ±1% tolerance

The KAL10FB1K00 is a direct substitute when tighter tolerance specifications are acceptable or required by circuit design. Both parts share identical mechanical mounting, thermal characteristics, and environmental compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the KAL10JB1K00 and KAL10FB1K00 are Active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on circuit tolerance requirements:

• KAL10JB1K00 is appropriate for applications where ±5% tolerance meets design specifications and cost optimization is prioritized.
• KAL10FB1K00 is appropriate for applications requiring tighter tolerance control at ±1%, providing enhanced precision without mechanical or thermal compromise.

Both parts maintain identical thermal performance, mechanical mounting compatibility, and environmental operating range. The substitution is electrically and mechanically transparent when tolerance requirements permit the use of the tighter-tolerance variant.

Frequently Asked Questions (FAQ)

Q: Can KAL10FB1K00 replace KAL10JB1K00 in existing designs?

A: Yes. The KAL10FB1K00 is a direct mechanical and thermal substitute. The only difference is tolerance specification (±1% versus ±5%). If your circuit design does not require the relaxed ±5% tolerance, the KAL10FB1K00 provides identical performance with enhanced precision.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions of 0.750" L x 0.800" W (19.05mm x 20.32mm) with a maximum seated height of 0.421" (10.70mm). PCB footprints and mounting hardware are interchangeable.

Q: Do both parts have the same thermal characteristics?

A: Yes. Both parts feature identical 12.5W power rating, ±20ppm/°C temperature coefficient, and -55°C to 275°C operating temperature range. Thermal dissipation and reliability are equivalent.

Q: What is the difference in tolerance between these parts?

A: KAL10JB1K00 provides ±5% tolerance, while KAL10FB1K00 provides ±1% tolerance. Both are wirewound 1 kOhms resistors. The tighter tolerance of the KAL10FB1K00 is suitable for precision applications requiring closer resistance values.

Q: Are both parts RoHS compliant?

A: Yes. Both KAL10JB1K00 and KAL10FB1K00 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
