Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AISC-0805-R22J-T is determined by strict equivalence across the following critical parameters:

• Inductance Value: 220 nH with ±5% tolerance
• Current Rating: 400 mA minimum continuous current capability
• Package / Case: 0805 (2012 Metric) surface mount form factor
• Core Type: Ceramic drum core wirewound construction
• Shielding Configuration: Unshielded
• DC Resistance: Maximum allowable DCR that does not exceed application requirements
• Compliance: ROHS3 compliance and EAR99 classification

The identified substitute IMC0805ERR22J01 from Vishay Dale meets these core substitution criteria while maintaining functional equivalence in the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the AISC-0805-R22J-T and IMC0805ERR22J01 are active production components with ROHS3 compliance and EAR99 classification. The substitute part IMC0805ERR22J01 provides equivalent inductance and current rating specifications within the 0805 package footprint.

The primary distinction is the DC resistance specification: the substitute offers a lower maximum DCR of 1Ohm compared to 1.1Ohm in the main part, which represents an improvement in resistive characteristics. The substitute also demonstrates a higher Q factor at 250MHz (50 versus 45) and marginally higher self-resonant frequency (860MHz versus 850MHz).

The operating temperature range differs: the main part supports -40°C to 125°C while the substitute supports -40°C to 105°C. Selection between these parts should account for application temperature requirements at the upper operating limit.

Both parts are available in tape and reel packaging and maintain unlimited moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can IMC0805ERR22J01 be used as a direct replacement for AISC-0805-R22J-T?

A: Yes, within the specified electrical and mechanical parameters. Both parts share identical inductance values (220 nH ±5%), current ratings (400 mA), package form factor (0805 / 2012 Metric), and core construction (ceramic drum core wirewound). The substitute offers lower DC resistance (1Ohm Max versus 1.1Ohm Max), which is advantageous for most applications.

Q: What is the impact of the different operating temperature ranges?

A: The main part AISC-0805-R22J-T operates to 125°C, while the substitute IMC0805ERR22J01 operates to 105°C. Applications requiring operation above 105°C must use the main part. For applications within the 105°C limit, both parts are functionally equivalent.

Q: Are there differences in physical dimensions between these parts?

A: Both parts conform to the 0805 (2012 Metric) package specification. The main part dimensions are 0.090" L x 0.068" W (2.29mm x 1.73mm) with 0.061" seated height. The substitute dimensions are 0.079" L x 0.049" W (2.00mm x 1.25mm) with 0.055" seated height. These dimensional variations remain within the 0805 package class and do not affect PCB footprint compatibility.

Q: What are the compliance and regulatory considerations?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

Q: How do the Q factor and self-resonant frequency compare?

A: The substitute IMC0805ERR22J01 exhibits a higher Q factor at 250MHz (50 versus 45) and a marginally higher self-resonant frequency (860MHz versus 850MHz). These characteristics indicate slightly improved high-frequency performance in the substitute part.
