ELFH12250 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The ELFH12250 is a 12-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 0.200" (5.08mm) pitch spacing. This shrouded 4-side header accommodates male pins and is rated for 15A at 300V UL. The component is actively produced and widely used in industrial control, power distribution, and signal routing applications where reliable solder termination and compact connector density are required. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, and mounting characteristics to ensure direct functional replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH12250 is determined by the following critical parameters:

Primary Matching Criteria:

• 12 positions per level with single level configuration
• 0.200" (5.08mm) pitch spacing
• Vertical orientation
• Male pin header type
• Through-hole solder termination
• Shrouded design (4-side or 2-side acceptable with mechanical verification)
• Minimum 300V UL voltage rating
• Minimum 12A current capacity
• UL94 V-0 flammability rating
• ROHS3 compliance

Acceptable Variations:

• Housing material (PBT, PA66, PA nylon acceptable)
• Insulation height (8.10mm to 12.00mm range acceptable)
• Contact tail length (3.30mm to 4.00mm range acceptable)
• Shroud configuration (4-side primary; 2-side acceptable with mechanical clearance verification)
• Operating temperature range (minimum -40°C to +105°C coverage required)

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Highest Compatibility):

The 0395316012 (Molex Eurostyle ESE 39531) and 1755833 (Phoenix Contact COMBICON MSTBVA) are the primary equivalents for the ELFH12250. Both maintain identical 12-position, 5.08mm pitch, vertical through-hole solder configuration with 4-side shrouding. All three parts meet UL94 V-0 flammability requirements and ROHS3 compliance. The 0395316012 matches the 15A UL current rating exactly. The 1755833 operates at 12A UL but maintains 300V UL voltage compatibility. Both substitute parts are actively produced with substantial inventory availability.

Secondary Equivalent (Mechanical Consideration):

The 1753631 (Phoenix Contact COMBICON MSTBV) operates at 5.00mm pitch versus the 5.08mm standard, representing a 0.08mm deviation. This part features 2-side shrouding instead of 4-side, reducing EMI shielding effectiveness. Current rating is 12A UL. This part is suitable only where mechanical clearance and reduced shroud coverage are acceptable in the application design.

Alternative Substitute (Mounting Verification Required):

The OSTOQ125450 (On Shore Technology OSTOQ) maintains 5.08mm pitch and 12-position configuration but specifies "Solder" mounting type rather than "Through Hole," indicating surface-mount or alternative termination methodology. This part requires verification of PCB pad layout compatibility before selection. Current rating is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the 1753631 (5.00mm pitch) be used in place of the ELFH12250 (5.08mm pitch)?

A: The 1753631 operates at 5.00mm pitch, a 0.08mm deviation from the 5.08mm standard. Direct substitution requires verification that PCB pad spacing accommodates this tolerance. The 2-side shroud configuration also differs from the 4-side design. Mechanical clearance assessment is mandatory before implementation.

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

A: 4-side shrouding (ELFH12250, 0395316012, 1755833) provides complete perimeter shielding around the connector body, offering enhanced EMI protection and mechanical stability. 2-side shrouding (1753631) covers only two opposing sides, reducing material and cost but providing less electromagnetic shielding. Selection depends on application EMI requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The ELFH12250 and all listed substitutes (0395316012, 1753631, 1755833, OSTOQ125450) are ROHS3 compliant, meeting EU Directive 2011/65/EU requirements for restricted hazardous substances.

Q: What is the current rating difference between the ELFH12250 and Phoenix Contact substitutes?

A: The ELFH12250 and 0395316012 (Molex) are rated for 15A UL. The Phoenix Contact parts (1753631 and 1755833) are rated for 12A UL. In applications requiring 15A continuous current, the Molex 0395316012 is the preferred substitute. For applications at or below 12A, Phoenix Contact parts are acceptable.

Q: Can the OSTOQ125450 be used as a direct replacement?

A: The OSTOQ125450 maintains 5.08mm pitch and 12-position configuration but specifies "Solder" mounting type. This designation indicates potential differences in termination methodology or PCB interface design compared to standard through-hole mounting. PCB pad layout and termination process compatibility must be verified before substitution.

Q: What operating temperature range should be considered for substitute selection?

A: The ELFH12250 operates from -40°C to +105°C. The 0395316012 (Molex) matches this range exactly. The OSTOQ125450 operates from -30°C to +105°C, providing slightly reduced low-temperature performance. Phoenix Contact parts do not specify operating temperature in available documentation. For applications requiring full -40°C to +105°C coverage, the Molex 0395316012 is the optimal substitute.

Q: Are there inventory considerations for substitute selection?

A: Current inventory levels are: ELFH12250 (919 pcs), 0395316012 (873 pcs), 1753631 (779 pcs), 1755833 (5027 pcs), and OSTOQ125450 (8381 pcs). The 1755833 and OSTOQ125450 offer the highest stock availability. For applications requiring immediate delivery, these parts should be prioritized.
