Substitute Part Grouping Explanation

Substitution eligibility for the ALVR0347R00FE12 is determined by strict equivalence across the following parameters:

• Resistance value: 47 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package: Axial
• Physical dimensions: 0.180" Dia x 0.500" L
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C ~ 250°C
• Moisture resistance feature
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1

The ALSR0347R00FE12 meets all substitution criteria as a parametric equivalent. Both parts are manufactured by Vishay Dale and share identical electrical and mechanical specifications, differing only in series designation (ALVR vs. ALSR).

Parameter Comparison

Engineering Selection Recommendations

Both the ALVR0347R00FE12 and ALSR0347R00FE12 are Active products with full ROHS3 compliance and identical environmental certifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. The ALSR0347R00FE12 currently maintains higher inventory levels (2827 Pcs vs. 1150 Pcs), which may influence procurement decisions for high-volume applications. Both parts satisfy identical electrical, mechanical, and regulatory requirements for through-hole axial resistor applications.

Frequently Asked Questions (FAQ)

Q: Can ALSR0347R00FE12 be used as a direct replacement for ALVR0347R00FE12?

A: Yes. Both parts are parametric equivalents with identical resistance, tolerance, power rating, physical dimensions, temperature characteristics, and compliance certifications. The difference in series designation (ALVR vs. ALSR) does not affect electrical or mechanical performance.
