Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LPSA800H10R0KB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 10 Ohms
• Power rating: 800W
• Composition: Thick Film
• Temperature coefficient: ±300ppm/°C
• Operating temperature range: -55°C to 175°C
• Mounting feature: Screw Holes
• Lead style: M4 Threaded
• Physical dimensions: 60.00mm x 57.00mm x 26.80mm (Max)
• Automotive AEC-Q200 certification
• Non-inductive construction

Allowable Variation Parameters:

• Tolerance: May vary from ±10% to tighter specifications (±5%)

The LPSA800H10R0JB qualifies as a substitute because it maintains all mandatory electrical and mechanical parameters while offering improved tolerance specification (±5% versus ±10%).

Parameter Comparison

Engineering Selection Recommendations

Both the LPSA800H10R0KB and LPSA800H10R0JB are active production components manufactured by Vishay Sfernice with full AEC-Q200 automotive compliance. Selection between these parts is based on tolerance requirements and inventory availability:

LPSA800H10R0KB Selection Criteria:

• Applications where ±10% tolerance specification is acceptable
• Current inventory availability of 681 pieces supports immediate procurement

LPSA800H10R0JB Selection Criteria:

• Applications requiring tighter tolerance control (±5%)
• Higher inventory availability (914 pieces) supports larger volume requirements
• Identical electrical performance and mechanical compatibility with the main part

Both components are suitable for direct substitution in chassis mount applications requiring 800W power dissipation at 10 Ohms resistance across the full automotive temperature range.

Frequently Asked Questions (FAQ)

Q: Can LPSA800H10R0JB replace LPSA800H10R0KB in existing designs?

A: Yes. The LPSA800H10R0JB maintains identical resistance, power rating, temperature coefficient, operating temperature range, physical dimensions, mounting configuration, and lead style. The substitute offers improved tolerance specification (±5% versus ±10%), making it suitable for direct substitution in all applications where the main part is specified.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. LPSA800H10R0KB provides ±10% tolerance, while LPSA800H10R0JB provides ±5% tolerance. All other electrical and mechanical parameters are identical.

Q: Are both parts automotive qualified?

A: Yes. Both LPSA800H10R0KB and LPSA800H10R0JB carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring high-power thick film resistors.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts measure 60.00mm length x 57.00mm width with a maximum seated height of 26.80mm. Both use M4 threaded leads for screw hole mounting.

Q: What is the temperature stability of these resistors?

A: Both parts have a temperature coefficient of ±300ppm/°C and operate across the range of -55°C to 175°C, providing consistent performance across automotive environmental conditions.

Q: Can these parts be used interchangeably in PCB designs?

A: These are chassis mount resistors with screw hole mounting, not PCB-mounted components. They are mounted directly to the chassis or heat sink using M4 threaded leads and are not interchangeable with surface mount or through-hole PCB components.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For applications where tighter tolerance control is beneficial, LPSA800H10R0JB (±5%) is appropriate. For applications where ±10% tolerance is acceptable, either part is suitable based on availability and procurement lead time.
