The parts are electrically and mechanically equivalent across all specified parameters, including capacitance, voltage rating, tolerance, operating temperature range, and physical dimensions.

Both components meet ROHS3 compliance requirements and maintain REACH Unaffected status. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions for either part.

Selection between these parts may be based on inventory availability, lead time, or supply chain considerations. The CD5CC080DO3F is available with 1092 pieces in stock, while the CMR03C8R0DOCM has 879 pieces in stock. Both parts are suitable for direct substitution in applications requiring 8 pF mica capacitors at 300 V with radial through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can the CD5CC080DO3F be used as a direct replacement for the CMR03C8R0DOCM?

A: Yes. The CD5CC080DO3F is a direct equivalent. Both parts share identical electrical specifications (8 pF, ±0.5 pF tolerance, 300 V rating), dielectric material (mica), operating temperature range (-55°C to 125°C), and mechanical characteristics (radial through-hole package, 0.118" lead spacing, identical physical dimensions). Both are ROHS3 compliant and REACH Unaffected.

Q: Are there any physical differences between these parts?

A: No. Both parts have identical physical dimensions of 0.272" L x 0.110" W (6.90 mm x 2.80 mm), maximum seated height of 0.189" (4.80 mm), and lead spacing of 0.118" (3.00 mm). They are mechanically interchangeable in PCB layouts.

Q: What parameters must match for substitution eligibility?

A: Substitution eligibility requires matching capacitance (8 pF), tolerance (±0.5 pF), voltage rating (300 V), dielectric material (mica), mounting type (through hole), package configuration (radial), lead spacing (0.118"), and physical dimensions. Compliance certifications (ROHS3, REACH Unaffected) and MSL rating (1) must also be equivalent.

Q: Do both parts have the same operating temperature range?

A: Yes. Both the CMR03C8R0DOCM and CD5CC080DO3F operate across the identical temperature range of -55°C to 125°C.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and carry MSL rating 1 (Unlimited). They meet identical regulatory and environmental standards.

Q: Which part should be selected based on availability?

A: Selection may be based on inventory status. The CD5CC080DO3F has 1092 pieces in stock, while the CMR03C8R0DOCM has 879 pieces in stock. Both are classified as Active products with no supply restrictions.
