Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 125LS10JJ-R are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

• Capacitance value: 10000 pF
• Tolerance: ±20%
• Voltage rating: 400VAC
• Temperature coefficient: Y5V (F)
• Operating temperature range: -30°C ~ 125°C
• Mounting type: Through Hole
• Package type: Radial, Disc
• Physical dimensions: 0.563" Dia (14.30mm)
• Lead spacing: 0.374" (9.50mm)
• Safety ratings: X1, Y4

All substitute parts listed maintain identical electrical performance and mechanical compatibility with the original part, differing only in packaging format (Bulk vs. standard) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 125LS10JJ-R is classified as Obsolete. Both substitute parts—125LS10-R and 125LS10GJ-R—are Active products within the same Vishay Cera-Mite 125L series and maintain full electrical and mechanical equivalence.

For new designs or ongoing production, either 125LS10-R or 125LS10GJ-R is suitable. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical safety ratings (X1, Y4) for use in safety-critical applications. The choice between these two substitutes depends on packaging requirements: 125LS10-R is available in Bulk packaging with 1501 units in stock, while 125LS10GJ-R is also available in Bulk packaging with 993 units in stock.

Frequently Asked Questions (FAQ)

Q: Can 125LS10-R or 125LS10GJ-R be used as direct replacements for 125LS10JJ-R?

A: Yes. Both parts are parametric equivalents with identical capacitance (10000 pF), voltage rating (400VAC), temperature coefficient (Y5V), operating temperature range (-30°C ~ 125°C), and physical dimensions. They are mechanically and electrically interchangeable.

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

A: Both parts are electrically and mechanically identical. The difference lies in the part number designation (suffix variation) and current product status. Both are Active products with equivalent performance and availability.

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

A: Yes. All three parts carry X1 and Y4 safety ratings and are designated for Safety applications, meeting the required compliance standards for safety-critical circuit protection.

Q: What is the lead spacing for these capacitors?

A: The lead spacing is 0.374" (9.50mm) for all parts, ensuring compatibility with standard PCB layouts designed for the original 125LS10JJ-R.

Q: Are these parts RoHS compliant?

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