Description and Introduction

PRECISION 2.5-VOLT REFERENCE The part **SG2503M** is manufactured by **SMC/LINFINIT**.  

### **Specifications:**  
- **Type:** Solenoid Valve  
- **Port Size:** 1/4" (NPT)  
- **Number of Ports:** 5/2 (5 ports, 2 positions)  
- **Voltage Options:** Typically available in 12V DC, 24V DC, 110V AC, and 220V AC  
- **Operating Pressure Range:** 0.15 to 0.7 MPa (21.7 to 101.5 psi)  
- **Fluid Compatibility:** Air (non-lubricated or lubricated)  
- **Body Material:** Brass  
- **Seal Material:** NBR (Nitrile Rubber)  
- **Response Time:** Fast (typically < 20 ms)  
- **Ambient Temperature Range:** -5°C to 60°C (23°F to 140°F)  

### **Descriptions & Features:**  
- **5/2 Solenoid Valve:** Allows for double-acting cylinder control with exhaust on both sides.  
- **Direct-Operated:** Does not require a minimum pressure to operate.  
- **Manual Override:** Some models include a manual override for testing or emergency operation.  
- **Compact Design:** Lightweight and space-saving for easy installation.  
- **High Flow Capacity:** Optimized for efficient air flow.  
- **Durable Construction:** Brass body and NBR seals ensure long service life.  
- **Wide Voltage Options:** Compatible with various power supplies.  

This valve is commonly used in automation, pneumatic systems, and industrial machinery.  

(Note: Exact specifications may vary based on the model variant. Always refer to the manufacturer's datasheet for precise details.)

Application Scenarios & Design Considerations

PRECISION 2.5-VOLT REFERENCE

Alternative Part Number

  • LT1004CZ-1.2 --: Precision 1.2V shunt voltage reference in TO-92, functionally similar to the SG2503M reference; well-documented and widely available.
  • LM385Z-1.2 --: 1.2V micropower shunt reference in TO-92 with comparable tolerance and current range, a common drop-in style replacement.
  • TL431ACLP --: Adjustable shunt reference that can be set to 1.2V or other values, offering design flexibility if exact fixed 1.2V is not mandatory.
  • LM25037MM --: Similar push-pull/current-mode PWM controller function with comparable voltage and current ratings, widely available and well documented.
  • UC2843BD1 --: Industry-standard current-mode PWM controller covering similar supply range and drive capability, usable as a functional substitute with minor circuit tuning.
  • SG3524N --: Classic regulating PWM controller with similar control architecture and output drive, suitable for drop-in style replacement in many designs.
  • UC3843 --: Industry-standard current-mode PWM controller with similar function and pinout, widely available and well documented as a replacement for SG2503-type regulators.
  • TL494 --: Versatile PWM control IC covering similar power-supply control functions, easy to source and commonly used as a cross-reference for SG-series PWM controllers.
  • SG3524 --: Classic PWM regulator IC from a different series with comparable control functionality, suitable when the SG2503M is unavailable.
  • 2N2219A --: General-purpose NPN transistor in a metal can package, widely available and often used as a substitute for small-signal switching and amplifier applications similar to the SG2503M.
