Substitute Part Grouping Explanation

Substitute parts for the 41JR30 are qualified based on matching the following critical parameters:

• Resistance value: 300 mOhms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Temperature coefficient: ±90ppm/°C
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Number of terminations: 2

Parts meeting all these specifications are electrically and mechanically interchangeable in circuit applications requiring this resistor value and performance class.

Parameter Comparison

Engineering Selection Recommendations

The 41JR30E is a direct parametric equivalent to the 41JR30, with all electrical and mechanical specifications identical. The primary distinction is RoHS compliance status: the 41JR30E is ROHS3 compliant, while the 41JR30 is RoHS non-compliant. Both parts maintain REACH Unaffected status and identical export classification (EAR99). Selection between these parts depends on regulatory requirements for the end application. The 41JR30E offers higher inventory availability (1064 pieces versus 720 pieces) and is supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the 41JR30E replace the 41JR30 in existing designs?

A: Yes. The 41JR30E is electrically and mechanically equivalent, with identical resistance, tolerance, power rating, temperature coefficient, and physical dimensions. Direct substitution is valid from a circuit performance perspective.

Q: What is the difference between 41JR30 and 41JR30E?

A: The parts are identical in all electrical and mechanical parameters. The 41JR30E is ROHS3 compliant, while the 41JR30 is RoHS non-compliant. Packaging differs: 41JR30E is supplied in bulk format.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory compliance requirements. For applications requiring RoHS3 compliance, the 41JR30E is the appropriate choice. Both parts are active products with adequate inventory.

Q: Are there any physical installation differences between these parts?

A: No. Both parts share identical axial package configuration, dimensions (0.126" Dia x 0.437" L), and two-termination through-hole design. PCB layout and mounting procedures are identical.

Q: What certifications apply to both parts?

A: Both the 41JR30 and 41JR30E carry EAR99 export classification, REACH Unaffected status, and HTSUS code 8533.21.0080. RoHS compliance differs as noted above.
