Parameter Comparison

Engineering Selection Recommendations

The 125LS10QF-R is classified as obsolete. Both substitute parts—125LS10-R and 125LS10GJ-R—are active products from the same manufacturer and series, offering continued availability for new designs and production replenishment.

Selection between the two active substitutes should be based on packaging requirements and inventory availability. The 125LS10-R is available in bulk packaging with 1501 units in stock. The 125LS10GJ-R is also available in bulk packaging with 993 units in stock. Both parts maintain identical electrical specifications, mechanical dimensions, and regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected).

For applications requiring safety-rated capacitors in AC mains filtering or coupling circuits, either substitute provides equivalent performance and certification status.

Frequently Asked Questions (FAQ)

Q: Can 125LS10-R or 125LS10GJ-R be used as direct replacements for 125LS10QF-R?

A: Yes. Both parts are parametric equivalents with identical capacitance, voltage rating, temperature coefficient, physical dimensions, lead spacing, and safety ratings. Direct PCB substitution is possible without circuit modification.

Q: What is the difference between 125LS10-R and 125LS10GJ-R?

A: Both parts are electrically and mechanically identical. The difference lies in packaging designation and inventory levels. Both are active products suitable for new procurement.

Q: Are these parts suitable for safety-critical applications?

A: Yes. All three parts carry X1 and Y4 safety ratings, indicating suitability for safety-rated applications. The Y4 rating designates these capacitors for use across the mains supply in safety applications.

Q: What is the lead spacing, and does it affect PCB compatibility?

A: Lead spacing is 0.374" (9.50mm) for all three parts. This standard spacing ensures compatibility with existing PCB designs without layout modification.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Why is the original part obsolete?

A: The 125LS10QF-R is classified as obsolete by the manufacturer. Active equivalents (125LS10-R and 125LS10GJ-R) from the same series provide continued functionality and availability for ongoing applications.
