EM221504V Terminal Block Header Equivalent & Substitute Parts

Part Overview

The EM221504V is a 4-position terminal block header manufactured by Eaton Electronics Division, part of the Euro-Mag EM2215 series. This component is a male pin, shrouded (4-side) vertical through-hole terminal block with 0.197" (5.00mm) pitch spacing, rated for 16 A at 300 V UL. The part is currently active in production with 1,155 units in stock.

Terminal block headers serve as connection interfaces in electronic assemblies, enabling reliable wire-to-board termination through solder mounting. Equivalent and substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements necessitate alternative electrical or mechanical specifications within compatible parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the EM221504V is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of positions: 4 (fixed requirement)
• Header orientation: Vertical (fixed requirement)
• Mounting type: Through hole (fixed requirement)
• Termination style: Solder (fixed requirement)
• Voltage rating: Minimum 300 V UL (EM221504V baseline)
• Current rating: Minimum 16 A UL (EM221504V baseline)
• Flammability rating: UL94 V-0 (fixed requirement)
• Contact mating finish: Tin (fixed requirement)

Secondary Compatibility Criteria:

• Pitch tolerance: 0.197" (5.00mm) or 0.200" (5.08mm) are mechanically compatible within standard PCB design tolerances
• Shrouding configuration: 2-side or 4-side shrouding both provide functional equivalence
• Housing material: Thermoplastic, Polyamide (PA), Polybutylene Terephthalate (PBT), or Liquid Crystal Polymer (LCP) all meet UL94 V-0 requirements
• Contact material: Brass or Copper Alloy both provide equivalent electrical performance
• Operating temperature range: Parts rated -40°C to 110°C or -50°C to 100°C are functionally equivalent to -55°C to 105°C

Substitute parts are grouped into two categories based on pitch specification: 5.00mm pitch (direct mechanical match) and 5.08mm pitch (minor tolerance variation acceptable in most applications).

Parameter Comparison

Engineering Selection Recommendations

Direct Pitch Match (5.00mm) - Preferred for Mechanical Compatibility:

The following parts maintain the exact 5.00mm pitch specification of the EM221504V:

• 1753479 (Phoenix Contact COMBICON MSTBV): Matches pitch, voltage, and flammability. Current rating of 12 A is below the EM221504V baseline of 16 A. Suitable for applications with maximum current draw of 12 A per position. RoHS3 compliant.

• 1755260 (Phoenix Contact COMBICON MSTBV): Matches pitch, voltage, and flammability. Current rating of 12 A is below the EM221504V baseline. Housing material is PBT. RoHS compliant.

• 282822-4 (TE Connectivity Buchanan): Matches pitch, voltage, and flammability. Current rating of 15 A approaches the EM221504V baseline of 16 A. Operating temperature range of -40°C to 110°C exceeds the EM221504V specification. RoHS compliant.

Minor Pitch Variation (5.08mm) - Acceptable for Most Applications:

The following parts use 5.08mm pitch, which represents a 0.08mm (0.003") tolerance variation. This is within standard PCB design tolerances and is mechanically compatible:

• 1146380000 (Weidmüller Omnimate SL): 5.08mm pitch, current rating of 18.5 A exceeds EM221504V baseline. Voltage rating 300 V UL matches. Operating temperature -50°C to 100°C is within acceptable range. RoHS compliant.

• 1758034 (Phoenix Contact COMBICON MSTBV): 5.08mm pitch, current rating of 12 A is below baseline. Voltage rating 300 V UL matches. RoHS3 compliant.

• 1955400 (Phoenix Contact COMBICON CCV): 5.08mm pitch, current rating of 10 A is below baseline. Voltage rating 300 V UL matches. Housing material is LCP. RoHS compliant.

• 282825-4 (TE Connectivity Buchanan): 5.08mm pitch, current rating of 15 A approaches baseline. Voltage rating 300 V UL matches. Operating temperature range -40°C to 110°C exceeds specification. Features side stacking capability. RoHS compliant.

• ELFH04250 (Amphenol PCD ELFH): 5.08mm pitch, 4-side shrouding matches EM221504V configuration. Current rating of 15 A approaches baseline. Voltage rating 300 V UL matches. Operating temperature -40°C to 105°C is within acceptable range. RoHS3 compliant.

• OSTOQ045350 (On Shore Technology OSTOQ): 5.08mm pitch, mounting type is solder (not through-hole). Current rating not specified. Voltage rating 300 V UL matches. Operating temperature -30°C to 105°C is within acceptable range. RoHS3 compliant.

Compliance Considerations:

The EM221504V is RoHS non-compliant. All substitute parts listed are RoHS compliant or RoHS3 compliant. Selection of a RoHS-compliant substitute is appropriate for new designs or when regulatory compliance is required. For legacy applications requiring RoHS non-compliant components, the EM221504V remains the only option from this list.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 5.08mm pitch terminal block for the 5.00mm EM221504V?

A: Yes. The 0.08mm pitch difference is within standard PCB design tolerances. Both 5.00mm and 5.08mm pitch terminal blocks are mechanically compatible with standard through-hole PCB layouts. However, verify your specific PCB design accommodates the minor spacing variation before implementation.

Q: What is the difference between 2-side and 4-side shrouding?

A: Shrouding refers to the plastic housing that surrounds the male pins. 4-side shrouding provides complete enclosure on all four sides, while 2-side shrouding provides enclosure on two opposing sides. Both configurations provide equivalent electrical performance and meet UL94 V-0 flammability requirements. The choice depends on PCB layout constraints and mechanical assembly requirements.

Q: Are all substitute parts rated for 16 A like the EM221504V?

A: No. Several substitutes have lower current ratings. The 282822-4 and 282825-4 are rated for 15 A. The 1753479, 1755260, 1758034, and 1955400 are rated for 12 A or lower. The 1146380000 is rated for 18.5 A, exceeding the EM221504V baseline. Select a substitute with a current rating equal to or greater than your application requirement.

Q: What is the significance of RoHS compliance?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the component does not contain restricted materials such as lead, cadmium, or hexavalent chromium. The EM221504V is RoHS non-compliant, meaning it may contain lead. All listed substitutes are RoHS compliant or RoHS3 compliant. For applications subject to RoHS regulations or environmental requirements, select a RoHS-compliant substitute.

Q: Can I use a substitute with a lower current rating than the EM221504V?

A: Only if your application current requirement is lower than the substitute's rating. The EM221504V is rated for 16 A. If your circuit draws 12 A or less, substitutes rated for 12 A (such as 1753479, 1755260, 1758034) are acceptable. If your circuit requires 16 A or higher, select a substitute rated for 15 A or higher (282822-4, 282825-4, ELFH04250, or 1146380000).

Q: What is the operating temperature range significance?

A: The EM221504V operates from -55°C to 105°C. Substitutes with narrower ranges (such as -50°C to 100°C or -40°C to 110°C) are functionally equivalent for most applications. Select a substitute with an operating temperature range that encompasses your application's minimum and maximum operating conditions.

Q: Is the OSTOQ045350 a suitable substitute?

A: The OSTOQ045350 has a mounting type listed as "Solder" rather than "Through Hole." This indicates a different mounting configuration. While it maintains the 5.08mm pitch, 4-position vertical orientation, and 300 V rating, the mounting type difference may affect PCB compatibility. Verify your PCB design accommodates solder mounting before selecting this part.

Q: What housing materials are available in the substitute parts?

A: Substitute parts use Thermoplastic, Polyamide (PA/Nylon), Polybutylene Terephthalate (PBT), or Liquid Crystal Polymer (LCP) housing materials. All meet UL94 V-0 flammability requirements. Material selection affects mechanical properties such as rigidity and temperature performance. The EM221504V uses Thermoplastic; the OSTOQ045350 also uses Thermoplastic for direct material equivalence.

Q: Can I mix different substitute parts in the same assembly?

A: Yes, provided each part meets the electrical and mechanical requirements of its specific circuit location. However, using identical parts throughout an assembly simplifies inventory management, documentation, and future maintenance. Mixing different manufacturers or series should be documented in the bill of materials and assembly instructions.
