Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EM257514VC is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 14
• Pitch: 0.200" (5.08mm)
• Header Orientation: Vertical
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting Type: Through Hole
• Voltage - UL: 300 V
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Current - UL: Substitute parts may operate at equal or lower current ratings (16 A or less)
• Operating Temperature Range: Substitute parts may have narrower or equivalent temperature ranges
• Contact Tail Length: Minor dimensional variations permitted within mechanical compatibility constraints
• Insulation Height: Variations acceptable if mechanical fit is maintained
• Housing Material: Thermoplastic or Polyamide (PA) Nylon acceptable
• Contact Material: Brass or unspecified acceptable

All identified substitute parts meet the mandatory matching parameters and are therefore electrically and mechanically compatible with the EM257514VC.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active status components with ROHS3 compliance, ensuring regulatory alignment with the EM257514VC. Selection among equivalent parts is based on the following engineering considerations:

Phoenix Contact 1755859: This substitute maintains identical pitch, position count, orientation, and UL voltage rating. The component operates at 12 A UL current, which is lower than the EM257514VC specification of 16 A. This part is suitable for applications where the circuit current requirement does not exceed 12 A. The COMBICON MSTBVA series housing is constructed from Polyamide (PA) Nylon with identical insulation height (0.472"), ensuring mechanical compatibility. Contact tail length is 0.154" (3.90mm) compared to the original 0.177" (4.50mm), requiring verification of PCB pad layout compatibility.

On Shore Technology EDSTLZ955/14: This substitute meets all mandatory electrical parameters including 14 positions, 5.08mm pitch, vertical orientation, and 300 V UL rating. The component operates across -30°C to 105°C, which is narrower than the EM257514VC range of -40°C to 105°C. This part is suitable for applications where the lower temperature limit of -30°C is acceptable. The insulation height of 0.154" (3.90mm) differs significantly from the original 0.472" (12.00mm), requiring mechanical fit verification before selection.

On Shore Technology OSTOQ145450: This substitute provides full electrical compatibility with 14 positions, 5.08mm pitch, vertical orientation, and 300 V UL rating. Operating temperature range of -30°C to 105°C is narrower than the original specification. The contact tail length of 0.157" (4.00mm) is closer to the original 0.177" (4.50mm) than other substitutes, reducing PCB layout modification risk. Housing material is Thermoplastic with insulation height of 0.472" (12.00mm), matching the original EM257514VC dimensions.

Frequently Asked Questions (FAQ)

Q: Can I use the Phoenix Contact 1755859 in place of the EM257514VC if my circuit operates at 10 A?

A: Yes. The Phoenix Contact 1755859 is rated for 12 A at UL voltage of 300 V, which exceeds the 10 A requirement. All other critical parameters including 14 positions, 5.08mm pitch, vertical orientation, shrouded (4 side) male pin configuration, and through hole mounting are identical to the EM257514VC. Verify PCB pad layout compatibility due to the shorter contact tail length of 0.154" (3.90mm) versus the original 0.177" (4.50mm).

Q: What is the primary difference between the EDSTLZ955/14 and the EM257514VC?

A: The EDSTLZ955/14 has a significantly reduced insulation height of 0.154" (3.90mm) compared to the EM257514VC insulation height of 0.472" (12.00mm). This dimensional difference requires mechanical fit verification on the PCB. Additionally, the operating temperature range is -30°C to 105°C versus -40°C to 105°C for the original part. All electrical parameters including voltage, position count, and pitch are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (1755859, EDSTLZ955/14, and OSTOQ145450) are ROHS3 compliant, matching the EM257514VC compliance status.

Q: Which substitute part has the closest physical dimensions to the EM257514VC?

A: The OSTOQ145450 provides the closest dimensional match. It has an insulation height of 0.472" (12.00mm) identical to the EM257514VC and a contact tail length of 0.157" (4.00mm), which is closer to the original 0.177" (4.50mm) than the other substitutes. The Phoenix Contact 1755859 and EDSTLZ955/14 have shorter contact tail lengths of 0.154" (3.90mm).

Q: Can I use the OSTOQ145450 in applications requiring operation at -40°C?

A: No. The OSTOQ145450 operating temperature range is -30°C to 105°C. For applications requiring operation at -40°C, the EM257514VC with its -40°C to 105°C range is the appropriate selection. The Phoenix Contact 1755859 does not specify a lower temperature limit, and the EDSTLZ955/14 is also limited to -30°C minimum.

Q: What mounting considerations apply when substituting these parts?

A: All substitute parts are designed for through hole or solder mounting on PCBs. The primary consideration is contact tail length variation. The EM257514VC has a contact tail length of 0.177" (4.50mm), while substitutes range from 0.154" (3.90mm) to 0.157" (4.00mm). Verify that PCB pad spacing and hole depth accommodate the specific contact tail length of the selected substitute part.

Q: Are there any current rating limitations I should consider?

A: Yes. The EM257514VC is rated for 16 A at UL voltage. The Phoenix Contact 1755859 is rated for 12 A. If your circuit requires current above 12 A, the 1755859 is not suitable. The EDSTLZ955/14 and OSTOQ145450 do not specify UL current ratings in the provided data. For applications requiring 16 A operation, the EM257514VC is the specified selection.
