EM257502HO Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The EM257502HO 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 (2-side) header with 90° right-angle orientation and 5.08mm pitch, designed for through-hole solder termination. The part is currently active in production with 1070 pieces in stock. Terminal block headers serve as connection interfaces in electronic assemblies, requiring equivalent substitutes when original stock is unavailable, when alternative sourcing is needed, or when design flexibility permits component standardization across multiple suppliers.

Primary Substitution Criteria (Must Match Exactly):

• Number of positions: 2
• Pitch: 0.200" (5.08mm)
• Header orientation: 90°, Right Angle
• Termination style: Solder
• Mounting type: Through Hole
• Voltage - UL: 300 V
• Material flammability rating: UL94 V-0
• Contact mating finish: Tin

Secondary Compatibility Parameters (Allowable Variations):

• Current - UL: Substitute must meet or exceed 16 A requirement
• Operating temperature range: Substitute must cover or exceed -40°C ~ 105°C
• Shrouding configuration: 2-side or 4-side shrouding acceptable
• Contact material: Brass or Copper Alloy acceptable
• Housing material: Thermoplastic, Polyamide (PA66), or Polybutylene Terephthalate (PBT) acceptable
• RoHS status: ROHS3 Compliant or RoHS Compliant acceptable

The four substitute parts listed (282814-2, 282815-2, ELFH02210, ELFH02220) meet all primary criteria and fall within acceptable secondary parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with current manufacturing status and meet the core electrical and mechanical specifications required for direct substitution with the EM257502HO.

282814-2 and 282815-2 (TE Connectivity Buchanan Series): Both parts are manufactured by TE Connectivity AMP Connectors and feature Polyamide (PA66) housing with Copper Alloy contacts. The 282814-2 includes interlocking side features, while 282815-2 includes side stacking capability. Both operate at -40°C ~ 110°C, exceeding the EM257502HO temperature range. Current rating is 15 A, which is 1 A below the original specification. Both are RoHS compliant. The 282814-2 carries MSL 1 (Unlimited) rating, while 282815-2 is ROHS3 compliant with MSL 1 (Unlimited). Inventory availability is high for both parts (5330 and 1193 pieces respectively).

ELFH02210 (Amphenol PCD): This part features 4-side shrouding compared to the 2-side shrouding of the EM257502HO, providing enhanced EMI shielding. Housing is Polybutylene Terephthalate (PBT) with Brass contacts. Operating temperature matches the original at -40°C ~ 105°C. Current rating is 15 A. ROHS3 compliant with MSL Not Applicable. Inventory is substantial at 4638 pieces. The 4-side shrouding configuration may require mechanical clearance verification in the target application.

ELFH02220 (Amphenol PCD): This part maintains 2-side shrouding identical to the EM257502HO. Housing is Polybutylene Terephthalate (PBT) with Brass contacts. Operating temperature matches the original at -40°C ~ 105°C. Current rating is 15 A. RoHS compliant with MSL 1 (Unlimited). Inventory is 988 pieces. Packaging is supplied in Tray format rather than Bulk. This part offers the closest mechanical and thermal profile match to the original.

All substitute parts carry ECCN EAR99 and HTSUS 8536.69.4040 classifications matching the original component.

Frequently Asked Questions (FAQ)

Q: Can 282814-2 or 282815-2 be used as direct replacements for EM257502HO despite the 15 A current rating versus 16 A?

A: The 15 A rating of both TE Connectivity parts is below the original 16 A specification. Substitution is permissible only if the application circuit design operates at or below 15 A maximum current. Circuit analysis must confirm that peak and continuous current demands do not exceed 15 A. If the application requires the full 16 A capability, these parts are not suitable substitutes.

Q: What is the significance of the 4-side shrouding on ELFH02210 compared to the 2-side shrouding of EM257502HO?

A: The 4-side shrouding on ELFH02210 provides additional shielding on all four sides of the header, which may offer improved EMI performance in noise-sensitive applications. However, the increased shrouding dimensions may affect mechanical fit in the target PCB layout. Physical clearance verification is required before substitution. If the original design accommodates only 2-side shrouding, ELFH02220 is the appropriate choice.

Q: Are the TE Connectivity Buchanan series parts (282814-2, 282815-2) mechanically compatible with the Eaton Euro-Mag EM2575 series?

A: Both TE Connectivity parts share identical pitch (5.08mm), orientation (90° right angle), position count (2), and termination method (solder through-hole). The primary mechanical difference is the housing material (Polyamide PA66 versus Thermoplastic) and contact material (Copper Alloy versus Brass). These differences do not prevent mechanical compatibility. However, the 282814-2 includes interlocking side features and 282815-2 includes side stacking features, which may affect board layout spacing. Verify that the target PCB layout accommodates these features or does not require them.

Q: What is the difference between ELFH02210 and ELFH02220 from Amphenol PCD?

A: Both parts are from the Amphenol ELFH series with identical electrical specifications (15 A, 300 V, -40°C ~ 105°C). The primary differences are: (1) ELFH02210 features 4-side shrouding while ELFH02220 features 2-side shrouding; (2) ELFH02210 has unspecified contact tail length while ELFH02220 specifies 0.155" (3.94mm); (3) ELFH02210 is supplied in Bulk packaging while ELFH02220 is supplied in Tray packaging; (4) ELFH02210 carries MSL Not Applicable while ELFH02220 carries MSL 1 (Unlimited). For applications requiring 2-side shrouding matching the original EM257502HO, ELFH02220 is the preferred choice.

Q: Do all substitute parts meet RoHS compliance requirements?

A: All four substitute parts are RoHS compliant. The EM257502HO, 282815-2, and ELFH02210 are specifically ROHS3 compliant. The 282814-2 is RoHS compliant, and ELFH02220 is RoHS compliant. All parts carry ECCN EAR99 classification. Verify specific RoHS compliance requirements for your application region and supply chain documentation.

Q: What is the impact of operating temperature range differences between the original and substitutes?

A: The EM257502HO operates at -40°C ~ 105°C. The TE Connectivity parts (282814-2, 282815-2) operate at -40°C ~ 110°C, providing 5°C additional high-temperature margin. The Amphenol parts (ELFH02210, ELFH02220) match the original range at -40°C ~ 105°C. If the application operates within the original -40°C ~ 105°C range, all substitutes are thermally compatible. If the application requires operation above 105°C, only the TE Connectivity parts provide additional margin.

Q: Which substitute part offers the best inventory availability?

A: ELFH02210 from Amphenol PCD offers the highest inventory at 4638 pieces. The 282814-2 from TE Connectivity offers 5330 pieces. The 282815-2 offers 1193 pieces, and ELFH02220 offers 988 pieces. For applications requiring immediate availability, ELFH02210 or 282814-2 are preferred.
