EM252504 Terminal Block Plug 4-Position 5MM Equivalent & Substitute Parts

Part Overview

The EM252504 is a 4-position terminal block plug manufactured by Eaton Electronics Division, part of the Euro-Mag EM2525 series. This component features female sockets with 0.197" (5.00mm) pitch spacing, 180° free-hanging in-line orientation, and screw-type rising cage clamp termination. The part is actively produced and maintains 1037 units in current inventory stock.

Terminal block plugs serve as connectors in industrial control systems, power distribution, and signal routing applications. Equivalent and substitute parts become necessary when original stock is unavailable, when procurement lead times require alternative sourcing, or when system design modifications necessitate compatible connector options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EM252504 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 4
• Pitch: 0.197" (5.00mm)
• Connector Type: Plug with Female Sockets
• Wire Entry Orientation: 180° Free Hanging (In-Line)
• Termination Style: Screw - Rising Cage Clamp
• Voltage Rating (UL): 300 V
• Screw Size: M3
• Torque Specification: 0.79 Nm (7.0 Lb-In)
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Current Rating (UL): Substitute must meet or exceed 16 A
• Wire Gauge Range: Substitute must accommodate 12-26 AWG minimum
• Operating Temperature Range: Substitute must cover -40°C to 105°C minimum
• Contact Material: Brass or Phosphor Bronze acceptable
• Housing Material: Thermoplastic or Polyamide (PA66) acceptable
• RoHS Compliance: ROHS3 Compliant required

The TE Connectivity AMP Connectors part number 796640-4 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: EM252504 (Eaton)

The EM252504 remains the preferred component when available. It is actively produced, maintains adequate inventory levels (1037 units), and meets all application requirements with a 16 A current rating.

Substitute Selection: 796640-4 (TE Connectivity)

The 796640-4 qualifies as a direct functional substitute when EM252504 stock is unavailable. Both components are actively produced and ROHS3 compliant. The substitute maintains mechanical and electrical compatibility across all critical parameters including pitch, connector type, termination method, voltage rating, screw specifications, and flammability rating.

Selection Consideration:

The 796640-4 carries a 15 A current rating compared to the EM252504's 16 A rating. This 1 A difference represents a 6.25% reduction in current capacity. Applications operating at or near the 16 A maximum should retain the original EM252504 specification. Applications with current requirements at or below 15 A may safely use the 796640-4 substitute without performance degradation.

Both components support the same operating temperature range of -40°C to 105°C (with the substitute rated to 110°C), identical screw torque specifications, and equivalent material flammability ratings. The 796640-4 supports an extended wire gauge range (12-30 AWG versus 12-26 AWG), providing additional flexibility for wire termination options.

Frequently Asked Questions (FAQ)

Q: Can the 796640-4 be used as a direct replacement for the EM252504 in all applications?

A: The 796640-4 is mechanically and electrically compatible with the EM252504 across all critical parameters. However, the 1 A lower current rating (15 A versus 16 A) requires verification that your application does not exceed 15 A continuous current. If your system operates at 16 A, the original EM252504 specification must be retained.

Q: Are the screw torque specifications identical between these parts?

A: Yes. Both the EM252504 and 796640-4 use M3 screws with identical torque specifications of 0.79 Nm (7.0 Lb-In). Installation procedures and torque wrench settings remain unchanged when substituting between these parts.

Q: What is the pitch spacing, and does it match between these connectors?

A: Both connectors feature 0.197" (5.00mm) pitch spacing. This identical center-to-center distance ensures mechanical interchangeability in mating applications and PCB layouts designed for either component.

Q: Do both parts support the same wire gauge range?

A: The EM252504 supports 12-26 AWG wire gauges. The 796640-4 supports an extended range of 12-30 AWG. Both parts accommodate the standard 12-26 AWG range, making them compatible for typical industrial applications. The substitute offers additional flexibility for smaller gauge wires if required.

Q: Are there differences in contact material between these parts?

A: The EM252504 uses brass contacts, while the 796640-4 uses phosphor bronze contacts. Both materials are acceptable for terminal block applications and provide equivalent electrical performance and corrosion resistance in standard industrial environments.

Q: What is the operating temperature range for each part?

A: The EM252504 operates from -40°C to 105°C. The 796640-4 operates from -40°C to 110°C. Both parts cover the standard industrial temperature range. The substitute provides an additional 5°C upper temperature margin.

Q: Are both parts RoHS compliant?

A: Yes. Both the EM252504 and 796640-4 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.

Q: What is the difference between the Euro-Mag EM2525 series and the Buchanan series?

A: These are different product series from different manufacturers. The EM252504 belongs to Eaton's Euro-Mag EM2525 series, while the 796640-4 belongs to TE Connectivity's Buchanan series. Despite different series designations, both components meet identical electrical and mechanical specifications for 4-position, 5MM pitch terminal block plugs.

Q: Can these parts be mixed in the same system?

A: Yes. Both components feature identical pitch spacing (5.00mm), connector type (plug with female sockets), and termination method (screw rising cage clamp). They can be used interchangeably in multi-connector applications, provided current requirements do not exceed 15 A per connector.

Q: What inventory levels are currently available?

A: The EM252504 maintains 1037 units in current stock. The 796640-4 maintains 785 units in current stock. Both parts are actively produced and available for immediate procurement.
