EM252516 16-Position Terminal Block Plug Equivalent & Substitute Parts

Part Overview

The Eaton EM252516 is a 16-position terminal block plug from the EUROMAG EM2525 series, designed for free-hanging in-line applications with 180° wire entry. This component features female sockets with 0.197" (5.00mm) pitch spacing and screw-type rising cage clamp termination. The part is currently active in production with 979 units in stock.

Equivalent and substitute parts are identified when components share identical or compatible electrical and mechanical specifications within the allowed parameter ranges for this terminal block category. Substitution becomes necessary when the primary part is unavailable, when inventory constraints require alternative sourcing, or when application requirements align with compatible alternatives.

• Free-hanging in-line mounting orientation
• 180° wire entry angle
• 300 V UL voltage rating
• UL94 V-0 flammability classification
• M3 screw size with 0.79 Nm torque specification

Allowable Variation Parameters:

• Current rating: UL specification may vary within the 15-16 A range
• Wire gauge range: AWG 12-30 and mm² 0.05-4mm² are compatible
• Operating temperature: Upper limit may extend to 110°C
• Contact material: Brass or Phosphor Bronze are acceptable
• Housing material: Thermoplastic or Polyamide (PA66) are acceptable
• Contact mating finish: Tin finish is standard across all variants

The TE Connectivity AMP Connectors part number 1-796640-6 meets all mandatory matching parameters and operates within allowable variation ranges for this application category.

Parameter Comparison

Engineering Selection Recommendations

EM252516 (Eaton - Electronics Division)

The EM252516 is the primary component specification. This part is active in production with 979 units currently in stock. It carries UL94 V-0 flammability certification and operates across the -40°C to 105°C temperature range. The 16 A UL current rating and brass contact material provide the specified performance baseline for this application.

1-796640-6 (TE Connectivity AMP Connectors)

The 1-796640-6 is a functionally equivalent substitute that meets all mandatory electrical and mechanical parameters. This part is also active in production with 778 units in stock. The substitute carries identical UL94 V-0 certification and operates across an extended temperature range (-40°C to 110°C). The 15 A UL current rating is compatible with applications designed for the 16 A primary specification. The phosphor bronze contact material and polyamide housing are acceptable alternatives within this terminal block category. The TE Connectivity part includes side stacking capability and extended wire gauge compatibility (12-30 AWG versus 12-24 AWG on the primary part).

Both parts are compliant with EAR99 export classification and share identical HTSUS coding. Selection between these components should be based on inventory availability, lead time requirements, and specific application constraints related to the extended temperature range or wire gauge flexibility offered by the substitute.

Frequently Asked Questions (FAQ)

Q: Can the 1-796640-6 be used as a direct replacement for the EM252516?

A: Yes. Both components share identical 16-position, 5.00mm pitch configuration with female sockets, screw-type rising cage clamp termination, and 180° free-hanging in-line mounting. Both carry UL94 V-0 certification and operate at 300 V UL. The 15 A rating of the substitute is compatible with the 16 A primary specification. All critical mechanical and electrical parameters align within allowable variation ranges.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Current rating: EM252516 is rated 16 A; 1-796640-6 is rated 15 A. (2) Operating temperature upper limit: EM252516 operates to 105°C; 1-796640-6 operates to 110°C. (3) Wire gauge range: EM252516 accepts 12-24 AWG; 1-796640-6 accepts 12-30 AWG. (4) Contact material: EM252516 uses brass; 1-796640-6 uses phosphor bronze. (5) Housing material: EM252516 uses thermoplastic; 1-796640-6 uses polyamide (PA66). (6) Insulation height: EM252516 is 0.570" (14.48mm); 1-796640-6 is 0.610" (15.49mm). (7) The TE Connectivity part includes side stacking capability.

Q: Are there any compatibility concerns with wire gauge differences?

A: No. The EM252516 wire gauge range of 12-24 AWG (0.25-4mm²) is fully contained within the 1-796640-6 range of 12-30 AWG (0.05-3mm²). The overlap range of 12-24 AWG (0.25-3mm²) covers all applications designed for the primary part.

Q: Does the insulation height difference affect mechanical fit?

A: The insulation height difference of 0.040" (1.01mm) represents a minor variation. Both parts maintain identical pitch spacing, position count, and mounting orientation. This variation is within normal mechanical tolerance for this terminal block category and does not affect functional compatibility in standard applications.

Q: Are both parts currently available?

A: Yes. The EM252516 has 979 units in stock. The 1-796640-6 has 778 units in stock. Both parts are active in production status.

Q: What certifications do these parts carry?

A: Both parts carry UL94 V-0 flammability certification, operate at 300 V UL, and share identical EAR99 export classification and 8536.90.4000 HTSUS coding. The 1-796640-6 additionally carries ROHS3 compliance and REACH affected status designations.

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

A: Yes, provided the application requirements do not exceed the 15 A current limit of the substitute part. Both components share identical pitch, position count, termination style, and mounting configuration. The extended temperature range of the 1-796640-6 (-40°C to 110°C versus -40°C to 105°C) provides additional operational margin in high-temperature environments.
