Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 125LS10QQ-R is determined by strict equivalence across the following parameters: capacitance value (10000 pF), tolerance (±20%), voltage rating (400VAC), temperature coefficient (Y5V), operating temperature range (-30°C ~ 125°C), mounting type (Through Hole), package configuration (Radial, Disc), physical dimensions, lead spacing, and safety ratings (X1, Y4). All substitute parts listed maintain 100% compliance with these specifications. The primary distinction between the main part and substitutes is product status: the 125LS10QQ-R is obsolete, while substitute parts 125LS10-R and 125LS10GJ-R are active products with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts—125LS10-R and 125LS10GJ-R—are direct parametric equivalents to the obsolete 125LS10QQ-R. Selection between the two active alternatives should be based on packaging preference and inventory availability. The 125LS10-R is available in bulk packaging with 1501 units in stock, while the 125LS10GJ-R is also bulk packaged with 993 units in stock. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical electrical and mechanical characteristics. For applications currently using the 125LS10QQ-R, either substitute part provides direct replacement capability without circuit redesign or PCB modification.

Frequently Asked Questions (FAQ)

Q: Can 125LS10-R and 125LS10GJ-R be used interchangeably with 125LS10QQ-R?

A: Yes. All three parts share identical electrical specifications (10000 pF, ±20%, 400VAC, Y5V), mechanical dimensions, lead spacing, and safety ratings. The substitute parts are direct replacements suitable for PCB assembly without modification.

Q: What is the difference between the substitute parts?

A: The 125LS10-R and 125LS10GJ-R are parametrically identical. Both are active products from Vishay Cera-Mite with the same electrical and mechanical characteristics. Differences are limited to packaging designation and current inventory levels.

Q: Why is the main part listed as obsolete?

A: The 125LS10QQ-R has been discontinued by the manufacturer. The substitute parts 125LS10-R and 125LS10GJ-R represent the current active product offerings that maintain full specification equivalence.

Q: Are there any compliance or certification differences?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical X1, Y4 safety ratings suitable for safety-critical applications.

Q: Can these parts be used in new designs?

A: Yes. The active substitute parts 125LS10-R and 125LS10GJ-R are suitable for new designs. The obsolete 125LS10QQ-R should not be specified for new applications.

Q: What is the lead spacing tolerance?

A: Lead spacing is 0.374" (9.50mm) for all three parts, ensuring compatibility with existing PCB layouts designed for the 125LS10QQ-R.
