Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 825F10K are identified based on electrical equivalence and mechanical compatibility. The primary substitution criterion is the matching of all critical electrical parameters: resistance value (10 kOhms), tolerance (±1%), power rating (25W), temperature coefficient (±20ppm/°C), and operating temperature range (-55°C to 275°C). Mechanical compatibility is ensured through identical housing material (aluminum), mounting feature (flanges), lead style (solder lugs), and physical dimensions. The substitute part 825F10KE maintains full electrical and mechanical equivalence to the main part while differing only in packaging configuration and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 825F10K and 825F10KE are active production parts from Ohmite's Metal-Mite®89 series with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements. The 825F10KE offers ROHS3 compliance, making it suitable for applications subject to RoHS directives. The 825F10K, while RoHS non-compliant, remains available for applications without RoHS requirements. Both parts are REACH Unaffected and classified under ECCN EAR99. Packaging configuration differs between the two parts: the 825F10K uses standard packaging while the 825F10KE is supplied in tray packaging. This distinction may influence procurement logistics and handling procedures but does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Are the 825F10K and 825F10KE electrically identical? A: Yes. Both parts have identical resistance value (10 kOhms), tolerance (±1%), power rating (25W), temperature coefficient (±20ppm/°C), and operating temperature range (-55°C to 275°C).

Q: What is the primary difference between these substitute parts? A: The primary differences are RoHS compliance status and packaging configuration. The 825F10KE is ROHS3 compliant and supplied in tray packaging, while the 825F10K is RoHS non-compliant with standard packaging.

Q: Can the 825F10KE be used as a direct replacement for the 825F10K? A: Yes, from an electrical and mechanical standpoint. The 825F10KE maintains identical dimensions, mounting features, and electrical characteristics. Selection should be based on compliance requirements and packaging needs.

Q: Are the physical dimensions identical between both parts? A: Yes. Both parts have identical dimensions of 1.062" L × 1.094" W (26.98mm × 27.79mm) with a maximum seated height of 0.556" (14.12mm).

Q: What is the significance of the packaging difference? A: The 825F10K uses standard box packaging while the 825F10KE uses tray packaging. This affects handling, storage, and procurement logistics but does not impact electrical performance or mechanical compatibility.

Q: Which part should be selected for RoHS-compliant applications? A: The 825F10KE is ROHS3 compliant and should be selected for applications requiring RoHS compliance.
