Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the YOKOGAWA SDV144-SE3. Always verify mechanical mounting, signal type, and action type before substitution.
- YOKOGAWA SDV144-SE1 – Same series, different output range; verify supply pressure compatibility
- YOKOGAWA SDV144-DE3 – Double-acting variant; requires double-acting actuator
- YOKOGAWA SDV100 Series (other variants) – Confirm suffix codes for action type and options
- Fisher FIELDVUE DVC6200 – Industry-standard HART digital positioner; widely used as cross-brand equivalent
- Siemens SIPART PS2 (6DR5…) – Compatible for single-acting pneumatic actuators with HART
- Rotork IQ / CVA Series – For electric actuator applications (not direct replacement)
- Metso Neles ND9000 – Alternative smart positioner with HART/FOUNDATION Fieldbus options
- ABB TZIDC / TZIDC-200 – Cross-brand equivalent for single-acting pneumatic positioners
Note: Cross-brand replacements require full mechanical and signal compatibility verification. Contact Konmask.com for application-specific guidance.

Selection Guide
Use the SDV144 model code structure to select the correct variant:
- SDV1 – Base model designation (SDV100 series)
- 4 – Housing type (4 = aluminum alloy, general purpose)
- 4 – Output type (4 = single-acting, spring-return)
- -SE – Single-acting, standard explosion protection
- 3 – Option suffix (3 = HART communication + local indicator)
Key selection criteria:
- Actuator action: Single-acting (SE) vs. Double-acting (DE)
- Communication protocol: HART vs. FOUNDATION Fieldbus vs. PROFIBUS PA
- Hazardous area classification: Zone 1/2 (ATEX/IECEx) or Division 1/2 (FM/CSA)
- Ambient temperature range required
- Enclosure material: Aluminum vs. Stainless Steel

Replacement & Compatibility FAQ
Q: Can the SDV144-SE3 replace a Fisher DVC6200?
A: Both are HART-compatible single-acting digital positioners. Mechanical mounting and supply pressure must be verified. Functional replacement is possible in most applications with appropriate bracket adaptation.
Q: Is the SDV144-SE3 compatible with FOUNDATION Fieldbus?
A: No. The SE3 suffix indicates HART communication. For FOUNDATION Fieldbus, select the SDV144-SF3 or equivalent FF variant.
Q: What is the difference between SDV144-SE3 and SDV144-SE1?
A: The suffix digit indicates output pressure range and options. Verify the exact output range and local indicator requirements against your application datasheet.
Q: Can I use this positioner on a double-acting actuator?
A: No. The SE (single-acting) variant is designed for spring-return actuators only. Use the SDV144-DE3 for double-acting actuators.
Q: Do you provide calibration certificates?
A: Factory calibration documentation is available for new OEM units. Contact us for specific certification requirements.
