Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 23J800 is determined by the following critical parameters:

• Resistance value must be exactly 800 Ohms
• Tolerance must be ±5% or tighter
• Power rating must be 3W or greater
• Composition must be wirewound
• Package must be axial configuration
• Temperature coefficient must be ±30ppm/°C or better
• Two-terminal configuration required

Parts meeting these criteria are electrically and mechanically interchangeable in circuit applications. The substitute parts listed below satisfy all mandatory parameters.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 23J800E is a direct equivalent with identical electrical and mechanical specifications. The primary distinction is RoHS3 compliance; select this part for applications requiring regulatory compliance with modern environmental standards.

The Vishay Dale ALSR03800R0JE12 is functionally equivalent with identical electrical parameters. This part offers an extended operating temperature range (-65°C ~ 250°C) compared to the main part, RoHS3 compliance, and moisture-resistant construction. Physical dimensions are slightly smaller (0.180" diameter vs. 0.220" diameter), which may affect PCB layout considerations. Both substitute parts are Active status components with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the Ohmite 23J800E be used as a direct replacement for the Ohmite 23J800?

A: Yes. Both parts share identical electrical specifications (800 Ohms, ±5%, 3W, ±30ppm/°C) and mechanical configuration (axial, 2 terminations). The primary difference is RoHS3 compliance status on the 23J800E.

Q: What are the physical dimension differences between substitute parts?

A: The Ohmite 23J800 and 23J800E are identical at 0.220" diameter × 0.516" length. The Vishay Dale ALSR03800R0JE12 is smaller at 0.180" diameter × 0.500" length. Verify PCB hole spacing and layout clearances before substitution.

Q: Are all three parts suitable for the same temperature range?

A: The Vishay Dale ALSR03800R0JE12 specifies an operating range of -65°C ~ 250°C. Operating temperature ranges are not specified for the Ohmite parts. For applications requiring extended temperature operation, the Vishay Dale part is the appropriate selection.

Q: What is the difference between the Ohmite 23J800 and 23J800E?

A: Both parts are electrically and mechanically identical. The 23J800E is RoHS3 compliant, while the 23J800 is RoHS non-compliant. Packaging differs: 23J800 is standard packaging, 23J800E is bulk packaging.

Q: Can the Vishay Dale ALSR03800R0JE12 be used in place of the Ohmite 23J800?

A: Yes. All critical electrical parameters match (800 Ohms, ±5%, 3W, ±30ppm/°C). The smaller physical dimensions require verification of PCB layout compatibility. The Vishay part offers moisture-resistant construction and extended temperature range as additional benefits.
