Key Parameters

Substitute Part Grouping Explanation

Substitution of the 29L334C is determined by the following critical parameters:

• Inductance Value: 330 µH (exact match required)
• Shielding: Shielded construction mandatory
• Mounting Type: Surface mount configuration
• Current Rating: Minimum 300 mA required
• DC Resistance: Maximum 1.67Ohm preferred; values up to 1.4Ohm acceptable
• Physical Dimensions: Footprint compatibility within 7.20mm x 7.20mm envelope
• Operating Temperature Range: Minimum -40°C to 85°C coverage

The SRR6028-331Y from Bourns Inc. meets these substitution criteria with matching inductance, shielded construction, surface mount configuration, and superior current rating (370 mA) and lower DC resistance (1.4Ohm Max).

Parameter Comparison

Engineering Selection Recommendations

The SRR6028-331Y is the qualified substitute for the 29L334C based on the following factors:

Product Status: The 29L334C is obsolete, while the SRR6028-331Y maintains active production status, ensuring long-term availability and supply chain stability.

Electrical Compatibility: Both components provide identical 330 µH inductance with shielded construction. The SRR6028-331Y offers improved electrical performance with 370 mA current rating (23% higher than the 300 mA requirement) and reduced DC resistance of 1.4Ohm compared to 1.67Ohm maximum.

Compliance: The SRR6028-331Y is ROHS3 compliant and carries REACH Unaffected status, meeting modern regulatory requirements. Both components are classified as EAR99 for export control purposes.

Thermal Performance: The SRR6028-331Y supports an extended operating temperature range of -40°C to 125°C, exceeding the 29L334C specification of -40°C to 85°C.

Physical Footprint: The SRR6028-331Y footprint (6.80mm x 6.80mm x 3.00mm) is slightly smaller than the 29L334C (7.20mm x 7.20mm x 3.15mm), providing improved board space efficiency while maintaining compatibility with existing PCB layouts designed for the original component.

Frequently Asked Questions (FAQ)

Q: Can the SRR6028-331Y directly replace the 29L334C on existing PCBs?

A: Yes. Both components are surface mount inductors with identical 330 µH inductance and shielded construction. The SRR6028-331Y has a smaller footprint (6.80mm vs 7.20mm), which is compatible with PCBs designed for the larger 29L334C. Verify PCB layout clearances for the reduced height (3.00mm vs 3.15mm).

Q: What are the key electrical differences between these parts?

A: The SRR6028-331Y provides superior electrical performance with 370 mA current rating versus 300 mA, and lower DC resistance of 1.4Ohm maximum versus 1.67Ohm maximum. Both maintain the same 330 µH inductance value and shielded configuration.

Q: Why is the 29L334C listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The SRR6028-331Y from Bourns is an active production equivalent that fulfills the same functional requirements with enhanced specifications and regulatory compliance.

Q: Are there any packaging differences?

A: The 29L334C uses nonstandard packaging, while the SRR6028-331Y is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: Does the SRR6028-331Y meet current environmental and compliance standards?

A: Yes. The SRR6028-331Y is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both components have MSL 1 (unlimited moisture sensitivity) ratings.
