Substitute Part Grouping Explanation

Substitution for the 125LS10RQ-R is based on strict electrical and mechanical parameter matching within the Vishay Cera-Mite 125L series. The following criteria determine valid substitutes:

• Identical capacitance value: 10000 pF
• Matching tolerance: ±20%
• Equivalent voltage rating: 400VAC
• Same temperature coefficient: Y5V (F)
• Identical operating temperature range: -30°C ~ 125°C
• Matching mechanical form factor: Radial, Disc configuration
• Identical lead spacing: 0.374" (9.50mm)
• Equivalent safety ratings: X1, Y4
• Compliance equivalence: ROHS3 Compliant, REACH Unaffected

The substitute parts 125LS10-R and 125LS10GJ-R meet all these criteria and are classified as active products, providing direct replacement capability for the obsolete 125LS10RQ-R.

Parameter Comparison

Engineering Selection Recommendations

• Product availability: 125LS10-R has 1501 units in stock; 125LS10GJ-R has 993 units in stock
• Packaging format: 125LS10-R is supplied in bulk packaging; 125LS10GJ-R is supplied in bulk packaging
• Compliance requirements: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory standards
• Safety-rated applications: Both parts carry X1, Y4 safety ratings, suitable for the original application context

Frequently Asked Questions (FAQ)

Q: Can 125LS10-R and 125LS10GJ-R be used interchangeably with 125LS10RQ-R?

A: Yes. Both substitute parts match all critical electrical parameters (capacitance, voltage rating, temperature coefficient, tolerance) and mechanical specifications (package type, lead spacing, dimensions) of the original part. The primary difference is product status: the original is obsolete while the substitutes are active.

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

A: Both parts are electrically and mechanically identical. They share the same capacitance, voltage rating, temperature coefficient, package configuration, and safety ratings. The difference lies in internal manufacturing designations (indicated by the "GJ" suffix in one variant), but this does not affect functional performance or compatibility.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All three parts share identical mechanical specifications: 0.563" diameter, 0.689" maximum seated height, and 0.374" lead spacing. They are direct physical replacements suitable for through-hole PCB mounting.

Q: Do the substitute parts meet the same safety and compliance standards?

A: Yes. Both 125LS10-R and 125LS10GJ-R are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original 125LS10RQ-R. Both carry X1, Y4 safety ratings for use in safety-critical applications.

Q: Which substitute should I select based on availability?

A: 125LS10-R has higher current inventory (1501 units) compared to 125LS10GJ-R (993 units). For applications requiring immediate availability, 125LS10-R is the preferred choice.
