Substitute Part Grouping Explanation

The 1210R-392J qualifies as a direct substitute for the 1210-392J based on identical electrical and mechanical parameters. Substitution is determined by the following criteria:

• Inductance Value: 3.9 µH (exact match)
• Tolerance: ±5% (exact match)
• Current Rating: 378 mA (exact match)
• DC Resistance: 1.3 Ohm Max (exact match)
• Package Format: 1210 (3225 Metric) (exact match)
• Mounting Type: Surface Mount (exact match)
• Operating Temperature: -55°C ~ 125°C (exact match)
• Core Material: Ferrite (exact match)
• Shielding Configuration: Unshielded (exact match)

Both parts share identical functional and mechanical specifications, confirming direct interchangeability for applications requiring these parameters.

Parameter Comparison

Engineering Selection Recommendations

The 1210R-392J provides functional equivalence to the 1210-392J with all electrical and mechanical parameters matching. The primary distinction between the parts is the RoHS compliance status: the 1210-392J is RoHS non-compliant, while the 1210R-392J is ROHS3 Compliant. Both parts maintain REACH Unaffected status. Selection should be based on regulatory requirements for the end application and supply availability, with the 1210R-392J offering enhanced compliance for applications requiring RoHS3 certification and currently providing higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 1210R-392J replace the 1210-392J in existing designs? A: Yes. The 1210R-392J is a direct substitute with identical electrical specifications (3.9 µH, ±5% tolerance, 378 mA current rating, 1.3 Ohm DCR) and mechanical properties (1210 package, surface mount configuration, identical physical dimensions).

Q: What is the key difference between these two part numbers? A: The primary difference is RoHS compliance status. The 1210-392J is RoHS non-compliant, while the 1210R-392J is ROHS3 Compliant. All functional and mechanical parameters are identical.

Q: Are the physical dimensions identical? A: Yes. Both parts share identical dimensions of 0.128" L x 0.095" W (3.25mm x 2.42mm) with a maximum seated height of 0.101" (2.57mm), confirming PCB compatibility and interchangeable placement.

Q: Do both parts have the same operating temperature range? A: Yes. Both the 1210-392J and 1210R-392J operate across the same temperature range of -55°C to 125°C.

Q: Can I use these parts interchangeably in moisture-sensitive environments? A: Both parts carry an MSL rating of 1 (Unlimited), indicating unlimited floor life and no special moisture handling requirements during storage or assembly.

Q: Which part should I specify for new designs? A: Design selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the 1210R-392J. Both parts are active and in stock; the 1210R-392J currently shows higher inventory availability.
