Substitute Part Grouping Explanation

Substitute parts for the LPSA600H4R70KB are identified based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.7 Ohms
• Power rating: 600W
• Composition: Thick Film
• Temperature coefficient: ±300ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Mounting feature: Screw Holes
• Lead style: M4 Threaded
• Physical dimensions: 60.00mm x 57.00mm x 26.80mm (Max)
• Series: LPSA 600
• Automotive qualification: AEC-Q200
• Compliance: RoHS3 Compliant

Variable Parameter Allowed:

• Tolerance: Tolerance specifications may vary between substitute parts while maintaining the same resistance value and power rating. Tighter tolerance ratings (lower percentage values) are acceptable substitutes for looser tolerance ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the LPSA600H4R70KB and LPSA600H4R70JB are Active products manufactured by Vishay Sfernice within the LPSA 600 series. Both components carry identical AEC-Q200 automotive qualification and RoHS3 compliance certifications, confirming suitability for regulated applications.

The primary distinction between these parts is tolerance specification. The LPSA600H4R70JB provides ±5% tolerance compared to the ±10% tolerance of the LPSA600H4R70KB. This tighter tolerance in the substitute part represents improved resistance accuracy while maintaining all other electrical and mechanical characteristics.

Selection between these parts depends on circuit requirements for resistance accuracy. Applications requiring tighter tolerance control should specify the LPSA600H4R70JB. Applications where ±10% tolerance is acceptable may use either part interchangeably.

Frequently Asked Questions (FAQ)

Q: Can LPSA600H4R70JB replace LPSA600H4R70KB in existing designs?

A: Yes. The LPSA600H4R70JB is a direct substitute. Both parts share identical resistance values, power ratings, physical dimensions, mounting configurations, and thermal characteristics. The substitute part provides improved tolerance specification (±5% versus ±10%), which is compatible with applications designed for the original part.

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

A: Tolerance defines the acceptable deviation range from the nominal resistance value. The LPSA600H4R70KB allows ±10% deviation from 4.7 Ohms (4.23 to 5.17 Ohms). The LPSA600H4R70JB allows ±5% deviation (4.465 to 4.935 Ohms). Tighter tolerance provides greater resistance accuracy and is suitable for applications requiring precise resistance values.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the LPSA600H4R70KB and LPSA600H4R70JB carry AEC-Q200 automotive qualification, confirming compliance with automotive reliability and quality standards.

Q: Do these parts require different mounting procedures?

A: No. Both parts feature identical M4 threaded lead styles and screw hole mounting features. Mechanical installation procedures are identical.

Q: Are there compliance differences between these parts?

A: No. Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Compliance certifications are identical.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±300ppm/°C.
