PE-0603CDR10JTT Equivalent & Substitute Parts

Part Overview

The PE-0603CDR10JTT is a 100 nH unshielded drum core wirewound inductor manufactured by Pulse Electronics, designed for surface mount applications in the 0603 (1608 Metric) package. This component is rated for 400 mA continuous current with a maximum DC resistance of 580 mOhm and operates across the temperature range of -40°C to 125°C. The part is currently active in production and RoHS compliant, making it suitable for modern electronic assemblies. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the PE-0603CDR10JTT is determined by the following critical parameters:

Inductance Value: Must be 100 nH with ±5% tolerance
Current Rating: Must support minimum 400 mA continuous current
Package / Case: Must be 0603 (1608 Metric) for mechanical and electrical compatibility
Mounting Type: Must be Surface Mount
Operating Temperature Range: Must cover -40°C to 125°C minimum
Shielding Configuration: Must be Unshielded
Product Status: Must be Active

The substitute part CW160808-R10J from Bourns Inc. meets all critical substitution criteria. While the DC resistance specification differs (710 mOhm versus 580 mOhm maximum), this variance remains within acceptable engineering tolerances for the 100 nH inductance class and does not compromise functional performance at the specified 400 mA current rating.

Engineering Selection Recommendations

Both the PE-0603CDR10JTT and CW160808-R10J are active production components with current regulatory compliance. The PE-0603CDR10JTT carries RoHS Compliant certification, while the CW160808-R10J carries ROHS3 Compliant certification, both meeting modern environmental standards. Both components are REACH Unaffected and classified under ECCN EAR99.

Selection between these parts should be based on availability, packaging format requirements (Bulk versus Tape & Reel), and DC resistance tolerance acceptance. The CW160808-R10J exhibits slightly higher DC resistance (710 mOhm versus 580 mOhm maximum), which results in marginally increased power dissipation in high-current applications. Both parts maintain identical inductance values, current ratings, temperature operating ranges, and self-resonant frequencies, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CW160808-R10J replace PE-0603CDR10JTT in all applications?

A: Yes, provided the application tolerates the higher DC resistance specification (710 mOhm versus 580 mOhm maximum). Both components deliver 100 nH inductance at ±5% tolerance, support 400 mA current rating, and operate across -40°C to 125°C. Verify power dissipation requirements in your specific circuit design.

Q: What is the difference in physical dimensions between these parts?

A: The PE-0603CDR10JTT measures 0.071" L x 0.049" W x 0.040" H (1.80mm x 1.24mm x 1.02mm), while the CW160808-R10J measures 0.065" L x 0.041" W x 0.047" H (1.65mm x 1.05mm x 1.20mm). Both fit the 0603 (1608 Metric) package footprint, but height differences may affect PCB layout in space-constrained designs.

Q: Are there packaging format differences?

A: Yes. The PE-0603CDR10JTT is supplied in Bulk packaging, while the CW160808-R10J is supplied in Tape & Reel (TR) format. Select based on your assembly process requirements and volume needs.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The PE-0603CDR10JTT is RoHS Compliant, and the CW160808-R10J is ROHS3 Compliant. Both are REACH Unaffected and classified as EAR99 for export purposes.

Q: What is the significance of the Q factor difference?

A: The PE-0603CDR10JTT specifies Q of 34 @ 150 MHz, while the CW160808-R10J specifies Q of 34 @ 250 MHz. Both achieve identical Q values but at different test frequencies. This reflects core material differences (Ceramic versus Alumina) but does not affect functional performance at the specified inductance and current ratings.
