CMR03F301JOYP Equivalent & Substitute Parts

Part Overview

The CMR03F301JOYP is a 300 pF mica capacitor rated for 50 V with radial through-hole mounting. This Cornell Dubilier Electronics component is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts is necessary when the primary part number is unavailable from inventory channels or when sourcing alternatives from authorized distributors.

Key Parameters

Substitute Part Grouping Explanation

The CMR03F301JOYP can be substituted with the CD5FY301JO3 based on the following critical parameters:

• Capacitance Match: Both parts are 300 pF
• Tolerance Match: Both parts maintain ±5% tolerance
• Voltage Rating Match: Both parts are rated 50 V
• Dielectric Material: Mica in both parts
• Temperature Range: Identical operating range of -55°C ~ 125°C
• Mounting Configuration: Both feature radial through-hole mounting
• Physical Compatibility: Identical lead spacing (0.118" / 3.00mm), dimensions (0.272" L x 0.169" W), and maximum seated height (0.228")
• MSL Rating: Both rated MSL 1 (Unlimited)

These parameter alignments ensure electrical and mechanical compatibility for direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CMR03F301JOYP and CD5FY301JO3 are active products from Cornell Dubilier Electronics with identical electrical and mechanical specifications. The primary distinction is compliance posture: the CMR03F301JOYP holds ROHS3 compliance and REACH Unaffected status, while the CD5FY301JO3 is RoHS non-compliant and REACH Affected.

For applications subject to ROHS3 or REACH regulatory requirements, the CMR03F301JOYP is the appropriate selection. For applications without such regulatory constraints, the CD5FY301JO3 is electrically and mechanically equivalent. The choice between these parts should be driven by the compliance requirements of the target application and product market.

Frequently Asked Questions (FAQ)

Q: Can the CD5FY301JO3 be used in place of the CMR03F301JOYP without circuit redesign?

A: Yes. The parts are electrically and mechanically identical across all specified parameters: capacitance, tolerance, voltage rating, temperature range, mounting type, lead spacing, and physical dimensions. Substitution does not require circuit modifications.

Q: What is the key difference between these two parts?

A: The CMR03F301JOYP is ROHS3 compliant and REACH Unaffected, while the CD5FY301JO3 is RoHS non-compliant and REACH Affected. Electrical performance and mechanical fit are identical.

Q: Are there any package or form factor differences?

A: No. Both parts use identical radial through-hole packaging with the same lead spacing (0.118" / 3.00mm), dimensions (0.272" L x 0.169" W), and maximum seated height (0.228" / 5.80mm). They are physically interchangeable on PCBs designed for either part.

Q: Can these parts be used in high-temperature applications?

A: Yes. Both parts are rated for continuous operation across the -55°C ~ 125°C temperature range, making them suitable for standard industrial and commercial temperature environments.

Q: What is the MSL rating, and why does it matter?

A: Both parts carry an MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage or handling during board assembly.
