Ohmite 91J180 Equivalent & Substitute Parts

Part Overview

The Ohmite 91J180 is a 180 Ohm, 1.5W wirewound axial resistor with ±5% tolerance and flame retardant coating. This through-hole component is designed for applications requiring reliable power dissipation and safety features in axial package configuration. The part maintains Active product status with 1006 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, procurement lead times, or application-specific packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 91J180 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Resistance value: 180 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 1.5W (exact match required)
• Composition: Wirewound (exact match required)
• Package configuration: Axial (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Physical dimensions: 0.142" Dia x 0.453" L (exact match required)
• Safety features: Flame retardant coating (exact match required)

The 91J18R qualifies as a parametric equivalent because all electrical and mechanical specifications are identical to the main part. Packaging format differences (Bulk vs. standard) do not affect electrical performance or mechanical fit in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 91J180 and 91J18R are Active status components manufactured by Ohmite within the Series 90 product line. Selection between these parts should be based on packaging and inventory availability requirements:

The 91J180 is available in standard packaging with 1006 units in stock. The 91J18R is available in Bulk packaging with 1093 units in stock. Both parts carry identical RoHS non-compliant status and EAR99 export classification, making them equivalent for regulatory and compliance purposes in applications where RoHS compliance is not a requirement.

For applications requiring RoHS-compliant alternatives or different electrical specifications, alternative part families must be evaluated separately.

Frequently Asked Questions (FAQ)

Q: Can the 91J18R be used as a direct replacement for the 91J180?

A: Yes. The 91J18R is a parametric equivalent with identical electrical specifications (180 Ohms, ±5%, 1.5W), composition (wirewound), temperature coefficient (±30ppm/°C), physical dimensions (0.142" Dia x 0.453" L), and safety features (flame retardant coating). The only difference is packaging format (Bulk vs. standard).

Q: What is the difference between the 91J180 and 91J18R packaging?

A: The 91J180 uses standard packaging, while the 91J18R uses Bulk packaging. Both contain identical components with the same electrical and mechanical properties. Packaging format does not affect circuit performance or mechanical fit.

Q: Are both parts suitable for the same circuit applications?

A: Yes. Both parts meet identical electrical and mechanical requirements for axial through-hole resistor applications requiring 180 Ohm resistance, 1.5W power dissipation, and flame retardant safety features.

Q: What compliance certifications apply to these parts?

A: Both parts are classified as RoHS non-compliant and carry EAR99 export classification. They are not suitable for applications requiring RoHS compliance.

Q: Can these parts be used in high-temperature environments?

A: Both parts operate with a temperature coefficient of ±30ppm/°C. Operating temperature limits are not specified in the provided data. Consult Ohmite technical documentation for specific temperature range specifications.
