Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASMPH-1008-1R0M-T is determined by the following critical parameters:

• Inductance value: 1 µH (exact match required)
• Current rating: 1.6 A minimum
• Package / Case: 1008 (2520 Metric) (mechanical compatibility)
• Mounting type: Surface Mount (assembly compatibility)
• Shielding: Shielded (electromagnetic performance)
• Material - Core: Ferrite (electrical characteristics)
• Tolerance: ±20% (specification alignment)

The CVH252009-1R0M from Bourns Inc. satisfies all substitution criteria. Both parts share identical inductance, current rating, package dimensions, mounting type, shielding configuration, and core material. The DC resistance specification of the substitute (55mOhm Max) is lower than the main part (60mOhm), which is acceptable within the tolerance band and represents improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the ASMPH-1008-1R0M-T and CVH252009-1R0M maintain Active product status, ensuring continued availability and manufacturing support. Both components are RoHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications. The CVH252009-1R0M offers an extended operating temperature range (-55°C to 125°C) compared to the ASMPH-1008-1R0M-T (-40°C to 85°C), providing broader thermal operational capability. Selection between these parts should be based on application-specific temperature requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the CVH252009-1R0M replace the ASMPH-1008-1R0M-T in existing designs?

A: Yes. Both parts share identical inductance (1 µH), current rating (1.6 A), package dimensions (1008 / 2520 Metric), and mounting type (Surface Mount). The mechanical and electrical compatibility is confirmed across all critical parameters.

Q: What is the significance of the DC resistance difference between these parts?

A: The CVH252009-1R0M specifies 55mOhm Max compared to the ASMPH-1008-1R0M-T at 60mOhm. This lower resistance in the substitute part represents improved performance and remains within acceptable tolerance specifications for the 1 µH inductance class.

Q: Are there any temperature-related considerations for substitution?

A: The CVH252009-1R0M operates across -55°C to 125°C, while the ASMPH-1008-1R0M-T operates across -40°C to 85°C. If the application requires operation below -40°C or above 85°C, the Bourns part provides extended thermal coverage.

Q: Do both parts require identical PCB footprints?

A: Yes. Both components use the 1008 (2520 Metric) package with identical dimensions (0.098" L x 0.079" W / 2.50mm x 2.00mm) and maximum seated height (0.039" / 1.00mm). No PCB layout modifications are required for substitution.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. No compliance barriers exist for substitution.
