Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCA11/5ER-U07S002 is determined by the following critical parameters:

• Inductance Values: Parallel inductance of 10.9µH and series inductance of 394µH at 10kHz must be matched or equivalent
• Isolation Voltage: 500Vrms isolation requirement must be maintained
• Mounting Configuration: Surface mount package type required
• Physical Footprint: Dimensions must accommodate PCB layout constraints (13.60mm × 13.00mm footprint)
• Operating Temperature Range: Minimum -40°C to 85°C capability required
• Application Compatibility: Configurable transformer suitable for DC/DC SMPS and capacitor charger circuits

The VPH1-0076-R from Eaton - Electronics Division meets these substitution criteria through matching inductance specifications, isolation voltage rating, surface mount configuration, and compatible physical dimensions.

Engineering Selection Recommendations

Primary Substitute: VPH1-0076-R (Eaton - Electronics Division)

The VPH1-0076-R is the designated manufacturer-recommended substitute for the obsolete PCA11/5ER-U07S002. Selection of this alternative is supported by:

• Active Product Status: The VPH1-0076-R maintains active production status, ensuring long-term availability and supply chain continuity
• Matching Inductance Specification: Parallel inductance of 10.9µH aligns with the primary electrical requirement
• RoHS Compliance: The substitute meets RoHS compliance standards, whereas the original part does not
• Extended Temperature Range: Operating temperature capability of -40°C to 125°C exceeds the original specification of -40°C to 85°C, providing thermal margin
• Compatible Mounting: Surface mount configuration and physical dimensions support direct PCB integration
• MSL Rating Equivalence: Both components share MSL 1 (Unlimited) rating, indicating identical moisture sensitivity handling

Dimensional Considerations: The VPH1-0076-R exhibits minor dimensional variations (length 12.90mm vs. 13.60mm, width 13.00mm vs. 9.20mm, height 6.20mm vs. 6.50mm). PCB layout verification is required to confirm footprint compatibility within existing designs.

Frequently Asked Questions (FAQ)

Q: What makes the VPH1-0076-R a valid substitute for the PCA11/5ER-U07S002?

A: The VPH1-0076-R matches the critical electrical parameters: 10.9µH parallel inductance, 500Vrms isolation capability, surface mount configuration, and operating temperature range of -40°C to 85°C minimum. Both components are designed for SMPS transformer and capacitor charger applications.

Q: Are there dimensional compatibility concerns when substituting the VPH1-0076-R?

A: Minor dimensional differences exist between the two parts. The VPH1-0076-R measures 12.90mm × 13.00mm × 6.20mm compared to the original 13.60mm × 9.20mm × 6.50mm. PCB layout verification is necessary to confirm the substitute fits within existing footprint constraints and clearance requirements.

Q: Does the VPH1-0076-R meet compliance requirements that the original part does not?

A: Yes. The VPH1-0076-R is RoHS compliant, whereas the PCA11/5ER-U07S002 is RoHS non-compliant. For applications requiring RoHS compliance, the VPH1-0076-R provides regulatory alignment.

Q: What is the significance of the extended operating temperature range in the VPH1-0076-R?

A: The VPH1-0076-R operates from -40°C to 125°C, compared to the original -40°C to 85°C. This extended upper temperature limit provides additional thermal margin and may improve reliability in thermally demanding applications.

Q: Are packaging formats different between the two parts?

A: The VPH1-0076-R is supplied in Tape & Reel (TR) format. Original packaging information for the PCA11/5ER-U07S002 is not specified in the available data. Confirm packaging compatibility with assembly and handling requirements.

Q: What should be verified before implementing the VPH1-0076-R as a substitute?

A: Verification should include: PCB footprint compatibility given dimensional variations, confirmation of 500Vrms isolation voltage requirement for the application, circuit performance validation with the substitute component, and compliance with any design-specific thermal or electrical constraints.
