Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25J330 are qualified based on the following critical parameters:

• Resistance value: 330 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Number of terminations: 2 (exact match required)

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 25J330E (Ohmite) serves as a direct equivalent with identical physical dimensions and electrical specifications. The primary distinction is RoHS3 compliance, making it suitable for applications requiring regulatory adherence to RoHS directives.

The ALSR05330R0JE12 (Vishay Dale) is a manufacturer-recommended substitute that maintains all core electrical parameters. Physical dimensions differ slightly (0.312" Dia x 0.875" L versus 0.276" Dia x 1.016" L), and it provides an extended operating temperature range of -65°C to 250°C. This part is also RoHS3 compliant and features moisture-resistant construction. Selection of this substitute requires verification of PCB layout compatibility due to dimensional variance.

For applications requiring RoHS compliance, either the 25J330E or ALSR05330R0JE12 is appropriate. For applications with extended temperature requirements, the ALSR05330R0JE12 is the qualified choice.

Frequently Asked Questions (FAQ)

Q: Can the 25J330E be used as a direct replacement for the 25J330?

A: Yes. The 25J330E maintains identical electrical specifications (330 Ohms, ±5%, 5W, ±30ppm/°C) and physical dimensions (0.276" Dia x 1.016" L). The primary difference is RoHS3 compliance status.

Q: What are the dimensional differences between the 25J330 and ALSR05330R0JE12?

A: The 25J330 measures 0.276" Dia x 1.016" L (7.00mm x 25.80mm), while the ALSR05330R0JE12 measures 0.312" Dia x 0.875" L (7.92mm x 22.23mm). PCB layout must accommodate these differences.

Q: Is the ALSR05330R0JE12 suitable for high-temperature applications?

A: The ALSR05330R0JE12 operates across -65°C to 250°C, providing extended temperature capability compared to the 25J330, for which operating temperature is not specified.

Q: Are all substitute parts wirewound axial resistors?

A: Yes. All listed parts—25J330, 25J330E, and ALSR05330R0JE12—are wirewound axial resistors with 2 terminations and identical resistance, tolerance, and power ratings.

Q: Which substitute part is recommended for RoHS-compliant applications?

A: Both the 25J330E and ALSR05330R0JE12 are RoHS3 compliant. Selection depends on dimensional constraints and temperature requirements.
