Substitute Part Grouping Explanation

Substitution of the PCMC042T-R47MN is based on the following critical parameters that must remain constant or compatible:

Fixed Parameters (Must Match):

• Inductance value: 470 nH
• Inductance tolerance: ±20%
• Shielding type: Unshielded
• Mounting type: Surface Mount
• Inductance test frequency: 100 kHz
• RoHS3 compliance
• REACH unaffected status

Allowable Parameter Variations:

• Current rating may increase (higher current capability is acceptable)
• DC resistance may decrease (lower resistance is acceptable)
• Saturation current may vary within acceptable operating margins
• Physical dimensions may vary within PCB layout constraints
• Packaging format may differ (tape & reel vs. bulk)

The PCMB042T-R47MS qualifies as a direct substitute based on matching inductance, tolerance, shielding, mounting type, and compliance certifications, while offering improved electrical performance characteristics.

Engineering Selection Recommendations

The PCMB042T-R47MS is the qualified substitute for the obsolete PCMC042T-R47MN. Selection of this substitute is based on the following engineering criteria:

Product Status Alignment: The PCMB042T-R47MS maintains active product status with Susumu, ensuring continued availability and supply chain stability compared to the obsolete PCMC042T-R47MN.

Electrical Performance: The substitute part delivers equivalent inductance (470 nH ±20%) and improved DC resistance characteristics (14 mOhm maximum versus 15.5 mOhm maximum). The increased continuous current rating (7 A versus 6 A) provides additional design margin without compromising circuit performance.

Compliance Certification: Both parts maintain identical RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution.

Physical Compatibility: The substitute part features reduced physical dimensions (length 4.15mm versus 4.50mm, height 1.80mm versus 2.00mm), which accommodates existing PCB layouts with improved space efficiency. The width dimension remains constant at 4.00mm.

Packaging Consideration: The substitute is supplied in tape & reel format, which is standard for production environments and offers advantages in automated assembly processes compared to bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the PCMB042T-R47MS be used as a direct replacement for the PCMC042T-R47MN in existing designs?

A: Yes. Both parts share identical inductance values (470 nH ±20%), unshielded configuration, surface mount mounting type, and compliance certifications. The substitute offers improved electrical performance with lower DC resistance and higher continuous current rating.

Q: What are the physical dimension differences between these parts?

A: The PCMB042T-R47MS is slightly smaller in length (4.15mm versus 4.50mm) and height (1.80mm versus 2.00mm), while maintaining the same width (4.00mm). These dimensional reductions typically improve PCB layout efficiency without requiring design modifications.

Q: Are there any electrical performance trade-offs when substituting to the PCMB042T-R47MS?

A: No trade-offs exist. The substitute part provides superior electrical characteristics: lower maximum DC resistance (14 mOhm versus 15.5 mOhm) and higher continuous current rating (7 A versus 6 A). The saturation current specification differs (9.5 A versus 11.5 A), but both values remain above the continuous current rating, maintaining adequate design margin.

Q: What is the difference between the packaging formats?

A: The PCMC042T-R47MN is supplied in bulk packaging, while the PCMB042T-R47MS is supplied in tape & reel (TR) format. Tape & reel packaging is standard for automated surface mount assembly and provides better component protection and handling efficiency in production environments.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the PCMC042T-R47MN and PCMB042T-R47MS are RoHS3 compliant and REACH unaffected, satisfying identical regulatory requirements for equivalent substitution.

Q: Why is the PCMC042T-R47MN classified as obsolete?

A: The PCMC042T-R47MN has been discontinued by Susumu. The PCMB042T-R47MS represents the active equivalent part that supersedes the obsolete model, ensuring continued design support and component availability.
