Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D25K50R is determined by strict equivalence across the following critical parameters:

• Resistance value: 50 Ohms
• Power rating: 25 W
• Adjustment mechanism: Slide adjustable
• Mounting configuration: Chassis mount
• Termination style: Solder lug
• Package type: Radial, 3 lead, tubular
• Overall length: 2.000" (50.80mm)
• Tolerance: ±10%

Both substitute parts meet these criteria. Dimensional variations within manufacturing tolerances (diameter specifications of 0.563" OD / 0.313" ID versus 0.559" OD / 0.311" ID) remain within acceptable mechanical compatibility for chassis mount applications. All parts share identical electrical specifications, functional design, and regulatory classification codes (ECCN: EAR99, HTSUS: 8533.39.0080).

Parameter Comparison

Engineering Selection Recommendations

D25K50RE (Ohmite): This direct Ohmite substitute maintains identical electrical and mechanical specifications to the D25K50R while providing ROHS3 compliance. Selection of D25K50RE is appropriate for applications requiring RoHS compliance or when supply continuity within the Dividohm®210 series is prioritized. Inventory availability is 868 units.

AVT02506E50R00KE (Vishay Huntington Electric Inc.): This cross-manufacturer substitute provides equivalent electrical performance and ROHS3 compliance with minor dimensional tolerances (0.559" OD / 0.311" ID versus 0.563" OD / 0.313" ID). The AVT series offers the highest current inventory level at 1150 units. Selection is appropriate when multi-source qualification is required or when Vishay component standardization is preferred. REACH status is listed as vendor undefined.

Both substitutes are active products with identical ECCN and HTSUS classifications, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can D25K50RE be used as a direct replacement for D25K50R?

A: Yes. D25K50RE is electrically and mechanically equivalent to D25K50R, sharing identical resistance (50 Ohms), power rating (25 W), adjustment type (slide), mounting configuration (chassis mount), termination (solder lug), package type (radial, 3 lead, tubular), and overall dimensions (2.000" length). The primary difference is RoHS compliance status.

Q: What are the dimensional differences between D25K50R and AVT02506E50R00KE?

A: The outer diameter (OD) differs by 0.004" (0.563" versus 0.559") and the inner diameter (ID) differs by 0.002" (0.313" versus 0.311"). These variations remain within standard manufacturing tolerances for chassis mount applications and do not affect functional compatibility or electrical performance.

Q: Which substitute should be selected for RoHS-compliant applications?

A: Both D25K50RE and AVT02506E50R00KE are ROHS3 compliant. D25K50RE maintains the same manufacturer and series as the original part, while AVT02506E50R00KE provides a qualified cross-manufacturer option.

Q: Are there any compliance or certification differences between the three parts?

A: D25K50R is RoHS non-compliant. Both D25K50RE and AVT02506E50R00KE are ROHS3 compliant. All three parts share identical ECCN (EAR99) and HTSUS (8533.39.0080) classifications. REACH status for AVT02506E50R00KE is listed as vendor undefined.

Q: What is the current inventory status for each part?

A: D25K50R: 773 units; D25K50RE: 868 units; AVT02506E50R00KE: 1150 units. All parts are listed as new original stock.
