• Inductance value: 100 µH (identical)
• Tolerance: ±10% (identical)
• Current rating: 4 A (identical)
• DC resistance: 80 mOhm Max (identical)
• Core material: Ferrite, unshielded drum core (identical)
• Mounting type: Through hole (identical)
• Package configuration: Radial, vertical cylinder (identical)
• Inductance test frequency: 1 kHz (identical)
• RoHS compliance: ROHS3 (identical)

The substitute part maintains electrical and mechanical compatibility with the original specification while offering extended operating temperature range and higher saturation current capability.

Parameter Comparison

Engineering Selection Recommendations

Both AIRD-02-101K and DC780R-104K are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific requirements:

The AIRD-02-101K operates within -25°C to 85°C and is suitable for standard industrial and consumer applications within this temperature envelope.

The DC780R-104K extends the operating temperature range to -55°C to 125°C, making it appropriate for automotive, aerospace, or extreme environment applications requiring broader thermal performance. The DC780R-104K also provides marginally higher saturation current (10.9 A versus 10 A), offering additional headroom in transient current conditions.

Both parts maintain identical electrical specifications for inductance, tolerance, current rating, and DC resistance, ensuring functional interchangeability within their respective temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Can DC780R-104K replace AIRD-02-101K in all applications?

A: Yes, provided the application operates within the AIRD-02-101K temperature range of -25°C to 85°C. The DC780R-104K is electrically and mechanically compatible with identical inductance, tolerance, current rating, and DC resistance specifications.

Q: What are the physical differences between these parts?

A: The AIRD-02-101K has a diameter of 0.827" (21.00 mm) and height of 0.827" (21.00 mm). The DC780R-104K has a slightly smaller diameter of 0.772" (19.60 mm) but similar height of 0.831" (21.10 mm). Both use radial, vertical cylinder packaging for through-hole mounting. Verify PCB layout clearances before substitution.

Q: Why would I choose DC780R-104K over AIRD-02-101K?

A: Select DC780R-104K for applications requiring extended temperature operation beyond 85°C or below -25°C, or when higher saturation current margin (10.9 A) is beneficial for transient protection.

Q: Are there any compliance differences?

A: Both parts are ROHS3 compliant and REACH unaffected. The AIRD-02-101K has MSL rating of 1 (Unlimited), while the DC780R-104K lists MSL as Not Applicable. Both are suitable for standard PCB assembly processes.

Q: What is the inductance test frequency for these parts?

A: Both parts are tested at 1 kHz inductance frequency, ensuring measurement consistency across the product line.
