EM257511VC 11-Position Terminal Block Header Equivalent & Substitute Parts

Part Overview

The EM257511VC is an 11-position terminal block header manufactured by Eaton - Electronics Division. This component is a male pin, shrouded (4-side) header with 0.200" (5.08mm) pitch spacing, designed for vertical through-hole mounting with solder termination. The part operates within the Euro-Mag EM2575 series and maintains Active product status. Alternative equivalent parts are necessary to support supply chain flexibility, inventory management, and design compatibility across different manufacturing environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EM257511VC is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 11
• Pitch: 0.200" (5.08mm)
• Header Orientation: Vertical
• Type: Header, Male Pins, Shrouded (4 Side)
• Termination Style: Solder
• Mounting Type: Through Hole
• Material Flammability Rating: UL94 V-0
• Insulation Height: 0.472" (12.00mm)

Allowable Variation Parameters:

• Current - UL: 15 A or higher (EM257511VC rated 16 A)
• Voltage - UL: 300 V or higher
• Operating Temperature: Must encompass or exceed -40°C ~ 105°C range
• Contact Tail Length: Variation acceptable within mechanical assembly constraints
• Housing Material: Thermoplastic, Polyamide (PA66), or Polybutylene Terephthalate (PBT)
• RoHS Status: ROHS3 Compliant or RoHS Compliant

The substitute parts 0395355011 (Molex) and 1809351 (Phoenix Contact) meet all mandatory matching parameters and fall within allowable variation ranges for electrical and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

EM257511VC (Eaton - Primary Part)

• Active product status with 892 units in stock
• ROHS3 Compliant certification
• Rated 16 A at 300 V UL
• Operating temperature range -40°C ~ 105°C
• Thermoplastic housing material

0395355011 (Molex - Substitute)

• Active product status with 728 units in stock
• ROHS3 Compliant certification
• Rated 15 A at 300 V UL (1 A lower than primary part)
• Extended operating temperature range -40°C ~ 115°C
• Polyamide (PA66) housing material with mating flange feature
• Contact tail length 0.150" (3.81mm) versus 0.177" (4.50mm) on primary part
• MSL rating 1 (Unlimited)

1809351 (Phoenix Contact - Substitute)

• Active product status with 765 units in stock
• RoHS Compliant certification
• Dual-rated: 12 A at 400 V IEC; 15 A at 300 V UL
• Polybutylene Terephthalate (PBT) housing material
• Contact tail length 0.154" (3.90mm)
• MSL rating 1 (Unlimited)

All three parts satisfy the mandatory matching parameters for 11-position, 5.08mm pitch, vertical, shrouded male pin headers with solder termination and UL94 V-0 flammability rating. Selection between these parts depends on specific application requirements regarding current capacity, temperature range, and mechanical fit constraints related to contact tail length variation.

Frequently Asked Questions (FAQ)

Q: Can 0395355011 (Molex) be used as a direct replacement for EM257511VC (Eaton)?

A: The 0395355011 is electrically and mechanically compatible as a substitute. Both parts share identical pitch (5.08mm), position count (11), orientation (vertical), type (shrouded male pin header), and flammability rating (UL94 V-0). The Molex part is rated 15 A at 300 V UL versus the Eaton part's 16 A at 300 V UL. The contact tail length differs (0.150" versus 0.177"), which may affect PCB assembly fit. Verify mechanical clearance in your specific application before substitution.

Q: What is the difference between the contact tail lengths of these three parts?

A: Contact tail length affects solder joint depth and PCB hole engagement. EM257511VC has 0.177" (4.50mm) tail length, 0395355011 has 0.150" (3.81mm), and 1809351 has 0.154" (3.90mm). Shorter tail lengths may reduce solder joint strength if PCB hole depth is not accommodated. Verify PCB design specifications before selecting a substitute with different tail length.

Q: Are all three parts RoHS compliant?

A: Yes. EM257511VC and 0395355011 are ROHS3 Compliant. 1809351 is RoHS Compliant. Both certifications meet current regulatory requirements for electronic component manufacturing.

Q: Which substitute part has the highest operating temperature rating?

A: The Molex 0395355011 is rated -40°C ~ 115°C, which exceeds the Eaton EM257511VC rating of -40°C ~ 105°C by 10°C. The Phoenix Contact 1809351 does not specify an operating temperature range in the provided data.

Q: Can I use 1809351 (Phoenix Contact) in applications requiring 16 A current capacity?

A: No. The 1809351 is rated 15 A at 300 V UL, which is 1 A below the EM257511VC rating of 16 A. For applications requiring 16 A capacity, use the primary EM257511VC part or verify that your actual current draw does not exceed 15 A before substituting with 1809351.

Q: What is the significance of the mating flange feature on the Molex 0395355011?

A: The mating flange is a mechanical feature that provides additional alignment and stability during connector mating operations. This feature does not affect electrical performance but may influence mechanical assembly procedures and connector engagement characteristics in your specific application.

Q: Are there any moisture sensitivity differences between these parts?

A: Yes. EM257511VC lists Moisture Sensitivity Level (MSL) as Not Applicable. Both 0395355011 and 1809351 are rated MSL 1 (Unlimited), indicating they can be stored and handled without moisture-related restrictions. This difference does not affect substitution eligibility but may simplify inventory management for the Molex and Phoenix Contact alternatives.
