API Delevan 6027-056 Equivalent & Substitute Parts

Part Overview

The API Delevan 6027-056 is a laminated core power transformer rated at 36VA with dual primary and secondary windings. The primary accepts 115V or 230V input, while the secondary provides configurable output of 28V (parallel) or 56V (series) with maximum currents of 1.3A and 650mA respectively. This through-hole mounted transformer features PC pin termination and 2500Vrms isolation rating.

The 6027-056 carries an obsolete product status. Locating direct replacements or functionally equivalent alternatives is necessary for ongoing system support, maintenance, and new production applications requiring this transformer specification.

• Secondary voltage outputs: 28V (parallel) and 56V (series)
• Output current ratings: 1.3A (parallel) and 650mA (series)
• Isolation voltage: 2500Vrms
• Winding configuration: Dual primary, dual secondary

Mechanical Parameters (Must Match):

• Core type: Laminated
• Mounting: Through hole
• Termination: PC pin
• Physical envelope: 66.68mm L × 55.55mm W × 39.67mm H maximum

The 6027R-056 satisfies all electrical and mechanical compatibility criteria, making it a direct functional equivalent for the obsolete 6027-056.

Parameter Comparison

Engineering Selection Recommendations

The 6027R-056 is the direct substitute for the obsolete 6027-056. All electrical specifications, mechanical dimensions, and functional parameters are identical between the two parts.

Selection Basis:

The 6027R-056 maintains active product status with current manufacturing support, whereas the 6027-056 is obsolete. For new designs, maintenance replacements, and production continuity, the 6027R-056 is the appropriate selection.

The 6027R-056 achieves ROHS3 compliance, exceeding the non-compliant status of the original 6027-056. This compliance improvement is beneficial for applications subject to environmental regulations without introducing any functional or electrical changes to the transformer.

Both parts share identical isolation voltage (2500Vrms), core construction (laminated), winding configuration (dual primary/secondary), and through-hole PC pin mounting. No circuit redesign or board layout modification is required when transitioning from 6027-056 to 6027R-056.

Frequently Asked Questions (FAQ)

Q: Can the 6027R-056 be used as a direct replacement for the 6027-056 without circuit modifications?

A: Yes. The 6027R-056 is electrically and mechanically identical to the 6027-056. All voltage ratings, current capacities, isolation specifications, and physical dimensions match exactly. No circuit changes are required.

Q: What is the primary difference between the 6027-056 and 6027R-056?

A: The 6027R-056 is the active production equivalent of the obsolete 6027-056. The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant). All functional and electrical parameters are identical.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both transformers have identical dimensions of 66.68mm length × 55.55mm width × 39.67mm seated height. Both use through-hole PC pin termination. No PCB layout changes are necessary.

Q: Does the 6027R-056 provide the same voltage isolation as the 6027-056?

A: Yes. Both parts provide 2500Vrms isolation voltage rating.

Q: Can the secondary windings be configured in both parallel and series modes on the 6027R-056?

A: Yes. The 6027R-056 has dual secondary windings that support both parallel configuration (28V at 1.3A maximum) and series configuration (56V at 650mA maximum), identical to the 6027-056.

Q: Is the 6027R-056 suitable for applications requiring RoHS compliance?

A: Yes. The 6027R-056 is ROHS3 compliant, making it suitable for applications with environmental compliance requirements.
