Equivalent & Substitute Parts for EM257502VC Terminal Block Header

Part Overview

The EM257502VC is a 2-position terminal block header manufactured by Eaton - Electronics Division, part of the Euro-Mag EM2575 series. This component is a male pin, shrouded (4-side) vertical through-hole terminal block with 0.200" (5.08mm) pitch spacing, rated for 16 A at 300 V UL. The part is active in production with 922 units currently in stock.

Equivalent and substitute parts are necessary when the original EM257502VC is unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits selection from compatible alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution logic for the EM257502VC is based on the following critical parameters:

Primary Substitution Criteria:

Number of Positions: 2 (exact match required)
Pitch: 0.200" (5.08mm) (exact match required)
Header Orientation: Vertical (exact match required)
Type: Male Pins, Shrouded (4 Side) (exact match required)
Termination Style: Solder (exact match required)
Mounting Type: Through Hole (exact match required)

Secondary Compatibility Parameters:

Voltage - UL: 300 V minimum
Operating Temperature: -40°C ~ 105°C (or equivalent range)
Material Flammability Rating: UL94 V-0
RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories based on pitch specification:

Category A: 5.08mm Pitch (Exact Pitch Match) Parts with 0.200" (5.08mm) pitch provide direct mechanical and electrical compatibility with the EM257502VC footprint.

Category B: 5.00mm Pitch (Near-Pitch Alternatives) Parts with 0.197" (5.00mm) pitch represent a 0.08mm deviation from the original specification. These parts are functionally equivalent but require PCB footprint verification before implementation.

Frequently Asked Questions (FAQ)

Q: Can I use a 5.00mm pitch part as a substitute for the 5.08mm pitch EM257502VC?

A: Parts with 5.00mm pitch (0.197") differ from the EM257502VC specification of 5.08mm (0.200") by 0.08mm. Substitution requires verification that the PCB footprint accommodates this dimensional variance. Direct board-level compatibility cannot be assumed without footprint confirmation.

Q: What is the current rating difference between the EM257502VC (16 A) and substitute parts (12-15 A)?

A: The EM257502VC is rated for 16 A UL, while Molex substitutes are rated 15 A UL and Phoenix Contact substitutes are rated 12 A UL. For applications requiring the full 16 A capacity, only Molex alternatives (0395311002, 0395316002) provide the closest current rating at 15 A. Phoenix Contact parts (1755736, 1755516) are suitable for applications requiring 12 A or less.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the EM257502VC specification.

Q: What is the difference between 4-side shrouded and 2-side shrouded terminal blocks?

A: The EM257502VC features 4-side shrouding, providing insulation on all four sides of the header. All recommended substitutes also feature 4-side shrouding. Two-side shrouded variants (Molex 0395210002, 0395215002, 0395310002, 0395315002) are not included as direct substitutes due to this mechanical difference.

Q: Which substitute part has the highest inventory availability?

A: Molex 0395311002 has the highest inventory with 31,377 units in stock, followed by Phoenix Contact 1755736 with 29,447 units.

Q: Do all substitute parts operate across the same temperature range as the EM257502VC?

A: The EM257502VC operates from -40°C to 105°C. Molex substitutes (0395311002, 0395316002, 0395216002) specify the same temperature range. Phoenix Contact parts (1755736, 1755516) do not specify an operating temperature range in the provided data.

Q: What is the voltage rating for all parts?

A: All parts are rated for 300 V UL. Phoenix Contact 1755736 additionally carries an IEC rating of 630 V, and Phoenix Contact 1755516 carries an IEC rating of 400 V.
