Substitute Part Grouping Explanation

Substitution of the PM628S-680-RC is permissible with the SRR6028-680Y based on the following critical parameters:

Electrical Equivalence Criteria:

• Identical inductance value: 68 µH
• Identical inductance tolerance: ±30%
• Identical current rating: 800 mA
• Identical saturation current: 600 mA
• Identical maximum DC resistance: 300 mOhm
• Identical shielding classification: Shielded
• Identical core material: Ferrite

Mechanical Compatibility Criteria:

• Identical mounting type: Surface Mount
• Identical physical dimensions: 6.80mm L x 6.80mm W x 3.00mm H
• Identical package classification: Nonstandard
• Identical operating temperature range: -40°C to 125°C

Compliance Equivalence:

• Both parts are ROHS3 Compliant
• Both parts have Moisture Sensitivity Level 1 (Unlimited)
• Both parts are REACH Unaffected

The SRR6028-680Y operates at a higher self-resonant frequency (15 MHz versus 10.5 MHz), which does not restrict substitution as this parameter represents an enhanced characteristic.

Parameter Comparison

Engineering Selection Recommendations

Both the PM628S-680-RC and SRR6028-680Y are Active status products manufactured by Bourns Inc. and maintain full compliance with ROHS3 and REACH regulations. Selection between these parts should be based on:

Availability and Inventory: The SRR6028-680Y currently maintains higher inventory levels (1900 Pcs) compared to the PM628S-680-RC (951 Pcs), making it suitable for high-volume production requirements.

Electrical Performance: Both parts deliver identical electrical specifications across all critical parameters including inductance, current rating, DC resistance, and quality factor. The SRR6028-680Y exhibits superior high-frequency performance with a self-resonant frequency of 15 MHz versus 10.5 MHz, which may provide advantages in applications operating near resonant frequencies.

Mechanical Compatibility: Identical physical dimensions and mounting characteristics ensure direct PCB layout compatibility without redesign requirements.

Compliance Status: Both parts satisfy equivalent regulatory and environmental standards, supporting use in regulated industries and applications requiring ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the SRR6028-680Y be used as a direct replacement for the PM628S-680-RC in existing designs?

A: Yes. Both parts share identical electrical specifications (68 µH inductance, 800 mA current rating, 300 mOhm DCR), identical physical dimensions (6.80mm x 6.80mm x 3.00mm), and identical mounting type (Surface Mount). No PCB redesign or circuit modification is required.

Q: What is the difference between the PM628S-680-RC and SRR6028-680Y?

A: The primary difference is the self-resonant frequency: PM628S-680-RC operates at 10.5 MHz while SRR6028-680Y operates at 15 MHz. All other electrical and mechanical parameters are identical. The SRR6028-680Y also maintains higher current inventory availability.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the PM628S-680-RC and SRR6028-680Y operate across the identical temperature range of -40°C to 125°C.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited), ensuring equivalent regulatory compliance.

Q: Which part should be selected for new designs?

A: Selection should be based on application-specific requirements and supply chain considerations. For applications where high-frequency performance is beneficial, the SRR6028-680Y with its 15 MHz self-resonant frequency may be preferred. For applications with existing inventory or specific series requirements, the PM628S-680-RC remains a valid choice. Both parts are Active status products suitable for production use.

Q: Are the package types identical?

A: Yes. Both parts use identical Nonstandard package classification and are supplied in Tape & Reel (TR) packaging for surface mount assembly.
