Key Parameters

Substitute Part Grouping Explanation

Substitution of the RL0809-332-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 3.3 mH with ±10% tolerance
• Mounting configuration: Through-hole radial vertical cylinder package
• Shielding classification: Unshielded
• Electrical performance: Current rating and DC resistance within acceptable operating margins

Secondary Compatibility Factors:

• Operating temperature range compatibility
• Saturation current characteristics
• Physical dimensions and footprint constraints
• Moisture sensitivity level and environmental ratings

The substitute part 13R335C from Murata Power Solutions Inc. meets the primary matching criteria with identical inductance value, tolerance, mounting type, and package configuration. The substitute demonstrates improved electrical performance with higher current rating (190 mA versus 170 mA) and lower DC resistance (7 Ohm versus 9.06 Ohm maximum).

Engineering Selection Recommendations

RL0809-332-R to 13R335C Substitution:

The 13R335C from Murata Power Solutions Inc. is an active production equivalent suitable for replacing the obsolete RL0809-332-R in applications where the following conditions are met:

1. Electrical Performance: The substitute provides superior electrical characteristics with 190 mA current rating (exceeding the original 170 mA requirement) and reduced DC resistance of 7 Ohm maximum (compared to 9.06 Ohm). These improvements result in lower power dissipation and enhanced thermal performance.

2. Temperature Derating: Applications operating exclusively within the -40°C to 85°C range are fully compatible. Designs requiring operation above 85°C up to 125°C require thermal analysis to confirm the substitute's performance adequacy.

3. Physical Footprint: The substitute exhibits larger physical dimensions (0.374" diameter and 0.531" height versus 0.311" diameter and 0.354" height). PCB layout verification is required to confirm space availability.

4. Compliance Status: The 13R335C carries RoHS3 compliance and REACH unaffected status, supporting modern regulatory requirements. The original RL0809-332-R carries EAR99 classification, as does the substitute.

5. Production Continuity: Selection of the 13R335C ensures access to active inventory and ongoing manufacturing support, eliminating obsolescence risk associated with the RL0809-332-R.

Frequently Asked Questions (FAQ)

Q: Can the 13R335C directly replace the RL0809-332-R without circuit modifications?

A: The 13R335C is electrically compatible for applications operating within -40°C to 85°C. The identical inductance value (3.3 mH) and tolerance (±10%) ensure functional equivalence. However, PCB layout verification is mandatory due to increased physical dimensions. No circuit modifications are required for electrical operation.

Q: What is the impact of the lower DC resistance in the 13R335C?

A: The 13R335C's 7 Ohm maximum DC resistance compared to the RL0809-332-R's 9.06 Ohm maximum results in reduced power dissipation and lower operating temperature. This represents an improvement in thermal performance and efficiency.

Q: Are there dimensional constraints that would prevent substitution?

A: Yes. The 13R335C is physically larger: 0.374" diameter (versus 0.311") and 0.531" height (versus 0.354"). PCB layout must accommodate these increased dimensions. Verify clearance to adjacent components and trace routing before implementation.

Q: How does the narrower operating temperature range of the 13R335C affect suitability?

A: The 13R335C operates from -40°C to 85°C, compared to the RL0809-332-R's -40°C to 125°C range. For applications with maximum operating temperatures at or below 85°C, the substitute is fully suitable. Applications requiring operation above 85°C require thermal analysis and may not be compatible.

Q: What is the significance of the RL0809-332-R being obsolete?

A: Obsolete status indicates the part is no longer manufactured by Eaton - Electronics Division. Existing inventory may be limited and future procurement uncertain. The 13R335C, classified as active production, provides assured long-term availability and supply chain continuity.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts carry EAR99 classification. The 13R335C includes RoHS3 compliance and REACH unaffected status, supporting modern regulatory frameworks. The RL0809-332-R's compliance documentation should be reviewed for specific application requirements.
