Substitute Part Grouping Explanation

The 1210R-104J qualifies as a direct substitute for the 1210-104J based on the following allowed parameters:

• Identical inductance value: 100 µH with ±5% tolerance
• Matching current rating: 120 mA
• Equivalent DC resistance: 13 Ohm maximum
• Same core material: Ferrite
• Identical shielding configuration: Unshielded
• Matching package dimensions: 1210 (3225 Metric) with 0.128" L x 0.095" W (3.25mm x 2.42mm)
• Identical mounting type: Surface Mount
• Equivalent operating temperature range: -55°C ~ 125°C
• Matching Q factor and self-resonant frequency specifications

Both parts are manufactured by API Delevan Inc. and maintain the same electrical and mechanical characteristics required for direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1210-104J and 1210R-104J maintain active product status and are suitable for direct substitution based on electrical and mechanical parameter equivalence. The primary distinction between these parts is regulatory compliance: the 1210R-104J carries ROHS3 compliance certification, while the 1210-104J is RoHS non-compliant. Selection between these parts should be determined by application requirements regarding environmental and regulatory standards. The 1210R-104J offers significantly higher inventory availability with 23,627 units in stock compared to 985 units for the 1210-104J. Both parts share identical REACH Unaffected status and MSL Level 1 moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the 1210R-104J replace the 1210-104J in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical inductance (100 µH), current rating (120 mA), DC resistance (13 Ohm max), package dimensions (1210/3225 Metric), and operating temperature range (-55°C ~ 125°C). Direct substitution is supported for applications where the electrical specifications match circuit requirements.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 1210R-104J is ROHS3 compliant, while the 1210-104J is RoHS non-compliant. All other electrical and mechanical parameters are identical. The 1210R-104J also has substantially higher inventory availability.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with dimensions of 0.128" L x 0.095" W (3.25mm x 2.42mm) and maximum seated height of 0.101" (2.57mm). They are mechanically interchangeable in PCB layouts.

Q: Do these parts have the same moisture sensitivity level?

A: Yes. Both the 1210-104J and 1210R-104J are classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the 1210R-104J is the appropriate choice. For applications without RoHS compliance mandates, either part meets the electrical specifications. The 1210R-104J offers the advantage of higher inventory availability.
