Substitute Part Grouping Explanation

Substitute parts for the WS5A3301J are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

• Resistance value: 3.3 kOhms (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: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 200°C (exact match required)
• Features: Flame retardant coating, pulse withstanding, safety construction (exact match required)
• Regulatory compliance: RoHS3 compliant, REACH unaffected (exact match required)

The WS5M3301J meets all substitution criteria and is classified as an equivalent part within the Bourns WS series.

Parameter Comparison

Engineering Selection Recommendations

Both WS5A3301J and WS5M3301J are Active status components with identical electrical specifications and full regulatory compliance. Selection between these parts is determined by physical space constraints and packaging requirements. The WS5A3301J features larger physical dimensions (8.50mm diameter x 24.50mm length), while the WS5M3301J provides a more compact form factor (6.50mm diameter x 17.50mm length). Both parts maintain equivalent electrical performance, temperature stability, and safety certifications. Component selection should be based on available board space and mechanical fit requirements within the target application.

Frequently Asked Questions (FAQ)

Q: Can WS5M3301J replace WS5A3301J in existing designs?

A: Yes, the WS5M3301J is electrically equivalent to the WS5A3301J. Both components share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The primary difference is physical size. Substitution is valid when the smaller dimensions of the WS5M3301J fit within the available board space.

Q: What is the key difference between WS5A3301J and WS5M3301J?

A: The components are electrically identical. The WS5A3301J measures 8.50mm diameter x 24.50mm length, while the WS5M3301J measures 6.50mm diameter x 17.50mm length. The WS5M3301J is supplied in Cut Tape packaging, whereas the WS5A3301J uses standard axial packaging.

Q: Are both parts RoHS3 compliant?

A: Yes, both WS5A3301J and WS5M3301J are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What applications require the 5W power rating of these resistors?

A: The 5W rating supports applications requiring higher power dissipation than standard thin-film resistors. Typical uses include power supply circuits, load resistors, and thermal management applications operating across the -55°C to 200°C temperature range.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Both parts maintain Active product status with identical safety features, flame retardant coating, and pulse withstanding capability. Interchangeability is determined by physical space availability and mechanical fit requirements, not electrical performance or reliability characteristics.
