Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for mica capacitors is determined by electrical and mechanical parameter equivalence. The primary parameters governing substitutability are:

• Capacitance Value: Must be exactly 240 pF
• Tolerance: Must be ±1% or tighter
• Voltage Rating: Must be 500 V or higher
• Dielectric Material: Must be Mica
• Mounting Type: Must be Through Hole
• Package Configuration: Must be Radial with 0.232" (5.90mm) lead spacing
• Physical Dimensions: Must match or be compatible with 0.461" L x 0.201" W (11.70mm x 5.10mm) and 0.382" (9.70mm) maximum seated height

The substitute part CD15FD241FO3 meets all these criteria, providing functional equivalence for circuit-level replacement. Differences in compliance certifications (RoHS status and REACH designation) are noted for procurement and regulatory considerations but do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CD15FD241FO3F and CD15FD241FO3 are parametrically equivalent in all electrical and mechanical specifications. Both parts are active products from the same manufacturer and series.

Selection between these parts should consider compliance requirements:

• CD15FD241FO3F is specified for applications requiring RoHS3 compliance and REACH unaffected status, suitable for regulated markets and applications with strict environmental and safety requirements.

• CD15FD241FO3 provides equivalent circuit performance and is available in higher inventory quantity (1243 units) but carries RoHS non-compliant and REACH affected designations. This part is appropriate for applications where these compliance requirements are not mandated.

Both parts are suitable for the same through-hole radial mounting context with identical lead spacing and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can CD15FD241FO3 be used as a direct replacement for CD15FD241FO3F?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (240 pF), tolerance (±1%), voltage rating (500 V), dielectric material (Mica), mounting type (Through Hole), package configuration (Radial), lead spacing (0.232"), and physical dimensions. The differences are in compliance certifications; CD15FD241FO3F is RoHS3 compliant and REACH unaffected, while CD15FD241FO3 is RoHS non-compliant and REACH affected. Selection depends on regulatory requirements for your application.

Q: Are there any mechanical compatibility issues between these parts?

A: No. Both parts share identical mounting specifications including through-hole radial configuration, lead spacing of 0.232" (5.90mm), and physical dimensions of 0.461" L x 0.201" W (11.70mm x 5.10mm) with a maximum seated height of 0.382" (9.70mm).

Q: What is the difference between ROHS3 compliant and RoHS non-compliant designations?

A: RoHS3 compliance indicates the part meets the Restriction of Hazardous Substances directive requirements. The non-compliant designation on CD15FD241FO3 indicates it does not meet these environmental standards. Use the RoHS3 compliant version (CD15FD241FO3F) for applications subject to EU environmental regulations or customer requirements mandating RoHS compliance.

Q: What does REACH Unaffected versus REACH Affected mean?

A: REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) is a regulatory framework for chemical substances. REACH Unaffected means the part is not subject to REACH restrictions; REACH Affected means it may be subject to REACH requirements. CD15FD241FO3F is not affected, while CD15FD241FO3 is affected by REACH. For applications requiring REACH compliance, the CD15FD241FO3F is the appropriate selection.

Q: Which part should I select if both are available?

A: Selection is based on compliance requirements. If your application requires RoHS3 compliance or REACH unaffected status, use CD15FD241FO3F. If compliance requirements do not apply and higher inventory availability is a priority, CD15FD241FO3 is the functional equivalent. Verify your application's regulatory obligations before finalizing part selection.
