Key Parameters

Substitute Part Grouping Explanation

Direct substitution for the 6012-028 is established based on matching electrical and mechanical parameters. The 6012R-028 qualifies as a drop-in equivalent because it maintains:

Electrical Parameters (Identical):

• Primary voltage: 115V
• Secondary voltage outputs: Parallel 14V / Series 28V
• Output current ratings: Parallel 80mA / Series 40mA
• Power capacity: 1.1VA
• Isolation voltage: 2500Vrms
• Winding configuration: Single primary, dual secondary

Mechanical Parameters (Identical):

• Core type: Laminated
• Mounting type: Through Hole
• Termination style: PC Pin
• Physical dimensions: 34.93mm L x 28.58mm W x 23.80mm H (seated)
• Weight: 0.17 lb (77.11 g)

The substitution is based strictly on these parameter matches. No deviations in electrical output or mechanical form factor exist between the main part and the substitute.

Engineering Selection Recommendations

The 6012R-028 is designated as the direct equivalent for the obsolete 6012-028. Selection between these parts should be based on the following criteria:

For New Designs: The 6012R-028 is recommended as the primary choice due to its active product status and RoHS3 compliance. This ensures continued availability and alignment with modern environmental and regulatory standards.

For Legacy System Maintenance: The 6012-028 remains functionally equivalent for applications requiring exact historical specifications. However, availability is limited to existing stock (713 units), and product status is obsolete.

Compliance Considerations: The 6012R-028 provides RoHS3 compliance, whereas the 6012-028 is non-compliant. Both parts maintain identical electrical performance and mechanical compatibility, ensuring seamless substitution at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can the 6012R-028 directly replace the 6012-028 in existing designs? A: Yes. The 6012R-028 provides electrical and mechanical equivalence with the 6012-028. All voltage outputs, current ratings, isolation specifications, and physical dimensions are identical. Direct substitution is supported.

Q: What is the primary difference between the 6012-028 and 6012R-028? A: The 6012R-028 is the active production equivalent of the obsolete 6012-028. Both deliver identical electrical and mechanical performance. The key difference is product status: the 6012R-028 is active with improved RoHS3 compliance, while the 6012-028 is obsolete with declining inventory.

Q: Are there any compatibility concerns when substituting these parts? A: No compatibility concerns exist. The parts are electrically interchangeable and mechanically identical in footprint, mounting type, and termination style. PCB-level integration requires no design modification.

Q: Does RoHS compliance affect electrical performance? A: No. RoHS compliance relates to material composition and environmental safety standards. Electrical performance, power rating, voltage output, and isolation specifications remain identical between the 6012-028 and 6012R-028.

Q: What should be considered when selecting between these two options? A: For new designs, choose the 6012R-028 due to active availability and RoHS3 compliance. For legacy system repairs or maintenance where original part specifications are required, the 6012-028 remains available while inventory persists. Both parts are electrically and mechanically compatible.
