Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 23J8K2 is determined by the following critical parameters:

• Electrical Match: Resistance value of 8.2 kOhms with ±5% tolerance
• Power Capacity: 3W minimum power rating
• Composition: Wirewound construction
• Package Compatibility: Axial through-hole form factor
• Temperature Coefficient: ±30ppm/°C performance specification
• Termination Count: 2-pin configuration

The Vishay Dale ALSR038K200JE12 meets all substitution criteria with identical electrical specifications and compatible mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

The Vishay Dale ALSR038K200JE12 is electrically and mechanically equivalent to the Ohmite 23J8K2 for applications requiring 8.2 kOhms ±5% 3W axial wirewound resistors. Both components share identical resistance, tolerance, power rating, temperature coefficient, and termination configuration.

The Vishay Dale substitute provides ROHS3 compliance, whereas the Ohmite original is RoHS non-compliant. The Vishay Dale component specifies an operating temperature range of -65°C ~ 250°C and includes moisture-resistant features with MSL rating of 1 (Unlimited). Physical dimensions differ slightly, with the Vishay Dale component measuring 0.180" diameter versus 0.220" for the Ohmite part.

Selection between these components should be based on compliance requirements, thermal operating conditions, and physical space constraints within the application.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Dale ALSR038K200JE12 directly replace the Ohmite 23J8K2 in existing designs?

A: Yes, from an electrical standpoint. Both components provide 8.2 kOhms ±5% at 3W with ±30ppm/°C temperature coefficient and axial through-hole packaging. Physical dimensions differ slightly; verify PCB layout clearances before substitution.

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

A: The Vishay Dale ALSR038K200JE12 is ROHS3 compliant with specified operating temperature range (-65°C ~ 250°C) and moisture-resistant features. The Ohmite 23J8K2 is RoHS non-compliant with flame retardant coating and safety features. Electrical performance is equivalent.

Q: Are there any packaging or handling differences?

A: The Vishay Dale component is supplied in Bulk packaging with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. The Ohmite part has MSL listed as Not Applicable. Both are 2-termination axial components suitable for through-hole PCB assembly.

Q: Which component should be selected for new designs?

A: Selection depends on regulatory and environmental requirements. For applications requiring RoHS3 compliance, select the Vishay Dale ALSR038K200JE12. For applications requiring flame retardant coating and safety features, retain the Ohmite 23J8K2. Electrical performance is equivalent for both.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: The Vishay Dale component is slightly smaller (0.180" Dia x 0.500" L) compared to the Ohmite part (0.220" Dia x 0.516" L). Verify PCB hole spacing and component clearances before substitution, as the smaller diameter may affect mechanical fit in some applications.
