KAL10JB5R00 Equivalent & Substitute Parts

Part Overview

The KAL10JB5R00 is a 5 Ohms ±5% 12.5W wirewound chassis mount resistor manufactured by Stackpole Electronics Inc. This component is designed for applications requiring precision current limiting, load balancing, and thermal management in industrial and power electronics circuits. The part maintains Active product status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified when design requirements allow tolerance relaxation, power rating adjustments, or when alternative manufacturers provide equivalent electrical and mechanical performance within specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KAL10JB5R00 is determined by the following criteria:

Primary Substitution Parameters:

• Resistance value must equal 5 Ohms
• Tolerance must be equal to or tighter than ±5%
• Power rating must be equal to or greater than 12.5W
• Temperature coefficient must be ±50ppm/°C or better
• Operating temperature range must encompass -55°C to 275°C
• Composition must be wirewound
• Housing type must be aluminum with flange mounting
• Lead style must be solder lugs
• Package configuration must be axial or box type
• RoHS3 compliance required

Identified Substitutes:

KAL10FB5R00 (Stackpole Electronics Inc) – Parametric equivalent with improved tolerance specification (±1% vs ±5%). Maintains identical power rating, temperature characteristics, and mechanical dimensions. Direct pin-compatible replacement with enhanced precision capability.

UAL10-5RF8 (Riedon) – Cross-manufacturer substitute with tighter tolerance (±1%) and reduced power rating (10W vs 12.5W). Mechanical dimensions remain within acceptable variance. Includes additional safety features: current sense capability, flame proof construction, and pulse withstanding rating. Suitable for applications where 10W power dissipation is sufficient.

Parameter Comparison

Engineering Selection Recommendations

KAL10FB5R00 Selection Criteria: Use this Stackpole Electronics Inc substitute when circuit design permits tolerance improvement from ±5% to ±1% without redesign. This part is identical in all mechanical and thermal specifications, providing direct compatibility with identical PCB footprint and mounting requirements. Both parts maintain Active product status with ROHS3 compliance and REACH unaffected certification. Selection of this part introduces no risk to existing designs while providing enhanced precision.

UAL10-5RF8 Selection Criteria: Use this Riedon substitute only when application power dissipation requirements do not exceed 10W. The 2.5W reduction in power rating represents the primary design constraint. Mechanical dimensions remain within acceptable tolerance variance (±0.002" length, ±0.001" width, -0.004" height). This part includes additional safety certifications: flame proof construction and pulse withstanding capability. Cross-manufacturer substitution requires verification that Riedon part availability and supply chain alignment meet procurement requirements. Both parts maintain Active product status with ROHS3 compliance and REACH unaffected certification.

Frequently Asked Questions (FAQ)

Q: Can KAL10FB5R00 be used as a direct replacement for KAL10JB5R00? A: Yes. The KAL10FB5R00 is a direct mechanical and electrical substitute. Identical dimensions, power rating, and thermal characteristics ensure pin-for-pin compatibility. The only difference is improved tolerance specification (±1% vs ±5%), which does not create compatibility issues.

Q: What is the primary limitation of UAL10-5RF8 as a substitute? A: The power rating is reduced from 12.5W to 10W. Applications requiring continuous power dissipation above 10W must use KAL10JB5R00 or KAL10FB5R00. Mechanical dimensions vary slightly but remain within acceptable tolerance for standard PCB mounting.

Q: Are all three parts RoHS3 compliant? A: Yes. KAL10JB5R00, KAL10FB5R00, and UAL10-5RF8 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What are the mechanical dimension differences between parts? A: KAL10JB5R00 and KAL10FB5R00 share identical dimensions: 0.750" L x 0.800" W with 0.421" seated height. UAL10-5RF8 dimensions are 0.752" L x 0.799" W with 0.417" seated height. These variations are within standard manufacturing tolerance and do not affect standard PCB footprint compatibility.

Q: Can UAL10-5RF8 be used in high-temperature applications? A: Yes. UAL10-5RF8 maintains the same operating temperature range (-55°C to 275°C) and temperature coefficient (±50ppm/°C) as the original part, ensuring equivalent thermal performance.

Q: What additional features does UAL10-5RF8 provide? A: UAL10-5RF8 includes current sense capability, flame proof construction, and pulse withstanding rating. These features provide enhanced safety characteristics for specific application requirements.
