Ohmite 25JR30 Equivalent & Substitute Parts

Part Overview

The Ohmite 25JR30 is a 300 milliohm, 5% tolerance, 5-watt axial wirewound resistor with flame retardant coating and safety features. This through-hole component is designed for applications requiring low-resistance, high-power dissipation in a compact axial package. The part is currently active in production with 791 pieces available in new original stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

The Ohmite 25JR30E is identified as a parametric equivalent to the 25JR30. Substitution is valid based on the following matching criteria:

• Resistance value: 300 mOhms (identical)
• Tolerance: ±5% (identical)
• Power rating: 5W (identical)
• Composition: Wirewound (identical)
• Package type: Axial (identical)
• Physical dimensions: 0.276" Dia x 1.016" L / 7.00mm x 25.80mm (identical)
• Features: Flame Retardant Coating, Safety (identical)
• Number of terminations: 2 (identical)
• Series: 20 (identical)

The primary difference between the main part and substitute is packaging format (tape/reel versus bulk) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 25JR30 and 25JR30E are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

• RoHS compliance requirements: The 25JR30E meets RoHS compliance standards, while the 25JR30 does not. Applications subject to RoHS regulations must use the 25JR30E.
• Packaging format: The 25JR30 is supplied in tape/reel format, while the 25JR30E is supplied in bulk packaging. Choose based on assembly process requirements and handling procedures.
• Inventory availability: The 25JR30E has higher stock availability (1190 pieces) compared to the 25JR30 (791 pieces).
• Regulatory environment: The 25JR30E carries MSL 1 (Unlimited) rating, indicating superior moisture handling characteristics for storage and logistics.

Frequently Asked Questions (FAQ)

Q: Can the 25JR30E be used as a direct replacement for the 25JR30?

A: Yes. The 25JR30E is electrically and mechanically equivalent. Both parts have identical resistance (300 mOhms), tolerance (±5%), power rating (5W), composition (wirewound), package type (axial), and physical dimensions (0.276" Dia x 1.016" L). Substitution is valid from a functional standpoint.

Q: What is the difference between the 25JR30 and 25JR30E?

A: The primary differences are packaging format (tape/reel versus bulk), RoHS compliance status (non-compliant versus compliant), and moisture sensitivity level rating. Electrical and mechanical performance are identical.

Q: Which part should I select for RoHS-compliant applications?

A: The 25JR30E is RoHS compliant and must be used for applications subject to RoHS regulations. The 25JR30 is RoHS non-compliant and is not suitable for such applications.

Q: Are there any thermal or operating temperature differences between these parts?

A: No operating temperature or temperature coefficient data is provided for either part. Both are specified identically for thermal characteristics based on available documentation.

Q: Can these parts be used interchangeably in automated assembly?

A: Packaging format differs between the parts. The 25JR30 is supplied in tape/reel format suitable for pick-and-place assembly, while the 25JR30E is supplied in bulk packaging. Verify compatibility with your assembly equipment and handling procedures before substitution.

Q: What is the significance of the MSL rating difference?

A: The 25JR30E carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling. The 25JR30 is rated as Not Applicable. The 25JR30E offers superior moisture tolerance characteristics.
