EM250504V Equivalent & Substitute Parts Reference

Part Overview

The EM250504V is a 4-position wire-to-board terminal block manufactured by Eaton Electronics Division, part of the Euro-Mag EM2505 series. This component is designed for horizontal PCB mounting with side entry wire termination using a screw-rising cage clamp mechanism. The part is currently active in production with 978 units in stock.

Terminal blocks of this specification are essential in applications requiring reliable wire-to-board connections with fixed pitch spacing and standardized electrical ratings. Equivalent parts are identified when they maintain compatibility across critical electrical, mechanical, and dimensional parameters while meeting the same regulatory compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EM250504V is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Positions Per Level: 4
• Pitch: 0.200" (5.08mm)
• Mating Orientation: Horizontal with Board
• Mounting Type: Through Hole
• Wire Termination: Screw - Rising Cage Clamp
• Screw Thread: M3
• Torque Specification: 0.79 Nm (7.0 Lb-In)
• Voltage Rating: 300 V
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

• Current Rating: Substitute must equal or exceed 16 A
• Wire Gauge Range: Substitute must accommodate the 12-26 AWG range or broader
• Operating Temperature: Substitute may differ if not specified for main part
• Housing Material: May vary (thermoplastic vs. polyamide) provided mechanical and electrical performance is maintained
• Contact and fastener plating: May vary provided corrosion resistance and electrical conductivity are equivalent

The TE Connectivity AMP Connectors part 282841-4 meets all mandatory matching parameters and exceeds performance in current rating (17.5 A vs. 16 A) and wire gauge accommodation (12-30 AWG vs. 12-26 AWG).

Engineering Selection Recommendations

EM250504V (Eaton Euro-Mag EM2505):

• Active product status with established supply chain
• ROHS3 compliant and EAR99 classified
• Suitable for applications requiring 16 A continuous current at 300 V
• Wire gauge accommodation: 12-26 AWG
• Current inventory: 978 units

282841-4 (TE Connectivity Buchanan):

• Active product status with higher inventory availability (4585 units)
• ROHS3 compliant and EAR99 classified
• Exceeds electrical performance requirements: 17.5 A continuous current at 300 V
• Extended wire gauge accommodation: 12-30 AWG
• Polyamide housing material provides enhanced mechanical durability
• MSL rating of 1 (Unlimited) indicates superior moisture resistance

Both parts satisfy identical regulatory compliance requirements (ROHS3, EAR99, HTSUS 8536.90.4000) and maintain functional equivalence across all critical parameters. Selection between these parts should be based on application-specific requirements for current capacity, wire gauge flexibility, material properties, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 282841-4 directly replace the EM250504V in existing designs?

A: Yes. Both parts maintain identical pitch (5.08mm), position count (4), mounting orientation (horizontal with board), and termination method (screw-rising cage clamp). PCB footprints are compatible. The 282841-4 exceeds electrical specifications (17.5 A vs. 16 A) and wire gauge range (12-30 AWG vs. 12-26 AWG), making it functionally equivalent for all applications where the EM250504V is specified.

Q: Are there any material compatibility differences between these parts?

A: The EM250504V uses thermoplastic housing while the 282841-4 uses polyamide (PA66/Nylon 6/6). Both materials provide adequate mechanical strength and insulation for the specified voltage (300 V) and current (16-17.5 A) ratings. Polyamide offers superior moisture resistance, as indicated by the 282841-4's MSL rating of 1 (Unlimited) versus the EM250504V's Not Applicable rating. For applications in high-humidity environments, the 282841-4 may provide enhanced reliability.

Q: What is the significance of the M3 screw thread specification?

A: The M3 screw thread is a critical mechanical parameter that ensures proper fastening torque (0.79 Nm / 7.0 Lb-In) for secure wire termination. Both the EM250504V and 282841-4 use identical M3 specifications, guaranteeing that installation procedures and torque requirements remain consistent during substitution.

Q: Does the wire gauge range difference affect substitution eligibility?

A: The 282841-4 accommodates a broader wire gauge range (12-30 AWG) compared to the EM250504V (12-26 AWG). This represents an enhancement rather than a limitation. Applications using 12-26 AWG conductors are fully compatible with the 282841-4. The extended range provides additional flexibility for future design modifications without requiring component changes.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the EM250504V and 282841-4 are ROHS3 compliant, meeting all current environmental and hazardous substance restrictions. Both are also classified as EAR99 for export control purposes and share the identical HTSUS code (8536.90.4000) for tariff classification.

Q: What inventory considerations should influence part selection?

A: The 282841-4 has significantly higher inventory availability (4585 units) compared to the EM250504V (978 units). For applications requiring immediate delivery or large-volume procurement, the 282841-4 may offer supply chain advantages. Both parts maintain active product status with established manufacturing support.
