ELFH12280 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH12280 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 male pin header operates at 15 A (UL) and 300 V (UL), with an operating temperature range of -40°C to 105°C. The component is actively produced and RoHS compliant, making it suitable for industrial control, power distribution, and signal interconnection applications. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, and termination compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELFH12280 are qualified based on the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed UL specifications (15 A, 300 V minimum)
• Mechanical Compatibility: 12-position configuration, 0.200" (5.08mm) pitch, vertical orientation, through-hole mounting
• Connector Type: Male pin header with shrouded design (4-side or 2-side shrouding acceptable for mechanical protection)
• Termination Method: Solder termination for PCB integration
• Environmental Compliance: RoHS compliance and UL94 V-0 flammability rating
• Contact and Housing Materials: Brass contacts and polyamide housing for durability and electrical performance

Three substitute parts meet these criteria: Molex 0395316012, Phoenix Contact 1753631, and Phoenix Contact 1755833.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1755833

The 1755833 provides the closest electrical and mechanical match to the ELFH12280. Both components feature 12-position, 0.200" (5.08mm) pitch, vertical through-hole configuration with 4-side shrouding. The 1755833 meets UL voltage requirements (300 V) and maintains UL94 V-0 flammability compliance. Contact tail length (0.154") and insulation height (0.472") are within acceptable tolerance of the original specification. ROHS3 compliance exceeds RoHS requirements. Current rating of 12 A (UL) is lower than the ELFH12280 (15 A); applications requiring 15 A operation must use the original part or Molex 0395316012.

Secondary Substitute: Molex 0395316012

The 0395316012 matches the ELFH12280 in all critical electrical parameters: 15 A (UL) current rating, 300 V (UL) voltage rating, and -40°C to 105°C operating temperature. Mechanical configuration is identical: 12-position, 0.200" (5.08mm) pitch, vertical through-hole with 4-side shrouding. UL94 V-0 flammability and ROHS3 compliance are maintained. The primary difference is contact tail length (0.130" vs. 0.155"), which may require PCB layout adjustment. This part is suitable for applications requiring full 15 A capacity.

Tertiary Substitute: Phoenix Contact 1753631

The 1753631 is a 12-position vertical through-hole header with 2-side shrouding and 0.197" (5.00mm) pitch. While mechanically and electrically compatible for most applications, the 0.03mm pitch deviation and reduced shrouding (2-side vs. 4-side) represent design differences. Current rating is limited to 12 A (UL). This part is suitable only for applications where pitch tolerance and reduced shrouding are acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use Phoenix Contact 1755833 as a direct replacement for ELFH12280?

A: The 1755833 is mechanically and electrically compatible for applications operating at 12 A or below. If your circuit requires the full 15 A rating of the ELFH12280, use Molex 0395316012 instead. Both substitute parts maintain identical pitch (5.08mm), position count (12), orientation (vertical), and shrouding (4-side).

Q: What is the significance of the contact tail length difference between ELFH12280 (0.155") and 0395316012 (0.130")?

A: Contact tail length affects PCB hole depth and solder joint formation. The 0.025" difference may require PCB layout verification to ensure adequate solder fillet formation and mechanical support. Consult PCB design guidelines for your specific application.

Q: Why does Phoenix Contact 1753631 have a different pitch (5.00mm vs. 5.08mm)?

A: The 1753631 operates at 5.00mm pitch, which is a 0.03mm deviation from the ELFH12280 standard. This part is suitable only if your PCB layout accommodates 5.00mm spacing. Verify PCB hole positioning before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. The ELFH12280 is RoHS Compliant, while all three substitute parts (0395316012, 1753631, 1755833) are ROHS3 Compliant, which exceeds RoHS requirements.

Q: What is the current rating limitation for Phoenix Contact parts?

A: Both Phoenix Contact substitutes (1753631 and 1755833) are rated at 12 A (UL), compared to the ELFH12280 and Molex 0395316012 at 15 A (UL). For applications requiring 15 A operation, use ELFH12280 or Molex 0395316012.

Q: Can I mix shrouding types (4-side vs. 2-side) in the same assembly?

A: Mechanically, yes. However, 4-side shrouding provides superior EMI shielding and mechanical protection. If EMI performance is critical, maintain consistent 4-side shrouding across the assembly using ELFH12280, 0395316012, or 1755833.
