Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPSA600H10R0KB is determined by the following critical parameters that must remain constant across equivalent parts:

Fixed Parameters (Must Match):

• Resistance value: 10 Ohms
• Power rating: 600W
• Composition: Thick Film
• Temperature coefficient: ±300ppm/°C
• Operating temperature range: -55°C to 155°C
• Mounting feature: Screw holes with M4 threaded leads
• Physical dimensions: 60.00mm x 57.00mm x 26.80mm (Max height)
• Series: LPSA 600
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3

Variable Parameters (Allowed to Differ):

• Tolerance specification: The LPSA600H10R0KB features ±10% tolerance. Substitute parts with tighter tolerance specifications (such as ±5%) are electrically and mechanically compatible and provide enhanced precision characteristics.

The LPSA600H10R0JB qualifies as a parametric equivalent because it maintains all fixed parameters while offering improved tolerance performance.

Parameter Comparison

Engineering Selection Recommendations

Both the LPSA600H10R0KB and LPSA600H10R0JB are Active products manufactured by Vishay Sfernice within the LPSA 600 series. Both components maintain identical mechanical and thermal specifications, including identical physical dimensions, mounting interfaces, and operating temperature ranges.

The primary distinction between these parts is the tolerance specification. The LPSA600H10R0JB provides ±5% tolerance compared to the ±10% tolerance of the LPSA600H10R0KB. This tighter tolerance in the substitute part results in more precise resistance values across the specified operating range.

Both parts carry identical automotive compliance certifications (AEC-Q200) and RoHS3 compliance status, confirming suitability for regulated applications. The mechanical compatibility is complete, with both parts featuring M4 threaded leads and screw hole mounting on identical chassis mount housings.

Selection between these parts should be based on tolerance requirements of the specific application circuit. Applications requiring tighter resistance tolerances should utilize the LPSA600H10R0JB. Applications where ±10% tolerance is acceptable may utilize either part based on inventory availability and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can the LPSA600H10R0JB directly replace the LPSA600H10R0KB in existing designs?

A: Yes. The LPSA600H10R0JB is mechanically and electrically compatible with the LPSA600H10R0KB. Both parts share identical physical dimensions, mounting interfaces (M4 threaded leads with screw holes), power ratings (600W), resistance values (10 Ohms), and operating temperature ranges (-55°C to 155°C). The substitute part features improved tolerance specification (±5% versus ±10%), which provides enhanced precision without requiring design modifications.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance specification defines the acceptable range of resistance variation from the nominal 10 Ohm value. The LPSA600H10R0KB allows resistance values between 9.0 and 11.0 Ohms (±10% tolerance). The LPSA600H10R0JB restricts resistance values to between 9.5 and 10.5 Ohms (±5% tolerance). Applications requiring tighter resistance control should specify the ±5% tolerance part. Applications where broader tolerance is acceptable may use either part.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the LPSA600H10R0KB and LPSA600H10R0JB carry AEC-Q200 automotive qualification, confirming suitability for automotive-grade applications. Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for automotive and industrial markets.

Q: Do these parts require different mounting procedures?

A: No. Both parts feature identical mounting specifications. Both utilize M4 threaded leads with screw hole mounting on chassis mount housings. Physical dimensions are identical (60.00mm length x 57.00mm width x 26.80mm maximum height), ensuring direct mechanical compatibility without modification to mounting hardware or PCB layouts.

Q: What thermal characteristics do these parts share?

A: Both parts maintain identical thermal specifications. The temperature coefficient is ±300ppm/°C for both parts, and both operate across the identical temperature range of -55°C to 155°C. Both are thick film composition resistors rated for 600W continuous power dissipation, ensuring equivalent thermal performance in high-power applications.

Q: Are there inventory considerations when selecting between these parts?

A: Current inventory shows 1084 pieces of LPSA600H10R0KB and 977 pieces of LPSA600H10R0JB in stock. Both parts are Active products with ongoing availability. Selection may consider inventory levels and lead time requirements for specific procurement timelines.
