ELFH12290 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH12290 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 component features male pins with 2-side shrouding, rated for 15A at 300V UL, and is constructed from brass contacts with polyamide housing. The part maintains active product status and full RoHS compliance. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative specifications better suit application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH12290 is determined by the following critical parameters: 12-position count, 0.200" (5.08mm) pitch spacing, vertical orientation, through-hole mounting, male pin configuration, solder termination, and compliance with UL 300V / 15A electrical ratings. Shrouding configuration (2-side vs. 4-side) represents a mechanical variation that does not affect electrical substitutability but may impact physical fit in constrained layouts. Housing material variations (PA46 vs. PA66) and contact tail length differences are acceptable within the tolerance of equivalent component selection, provided core electrical and positional specifications remain constant.

The substitute parts listed below meet these core substitution criteria:

• 0395316012 (Molex Eurostyle ESE 39531): Matches 12-position, 5.08mm pitch, vertical through-hole, 15A/300V UL ratings. Features 4-side shrouding and PA66 housing.
• 1753631 (Phoenix Contact COMBICON MSTBV): Matches 12-position, vertical through-hole, solder termination. Pitch is 0.197" (5.00mm), representing a minor tolerance variation. Rated 12A/300V UL.
• 1755833 (Phoenix Contact COMBICON MSTBVA): Matches 12-position, 5.08mm pitch, vertical through-hole, 12A/300V UL ratings. Features 4-side shrouding and PA nylon housing.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and meet UL94 V-0 flammability requirements, ensuring compliance with standard safety certifications. The ELFH12290, 0395316012, and 1755833 share identical 5.08mm pitch spacing and are electrically interchangeable for applications requiring 12-position vertical through-hole terminal blocks. The 0395316012 (Molex) provides equivalent 15A current capacity and is recommended where 4-side shrouding offers improved mechanical protection in high-density PCB layouts. The 1755833 (Phoenix Contact) provides 4-side shrouding with ROHS3 compliance and is suitable for applications where enhanced environmental protection is required, though current capacity is rated at 12A. The 1753631 (Phoenix Contact) operates at 5.00mm pitch, representing a 0.08mm tolerance deviation from the primary specification; this part is suitable only where PCB footprint design accommodates the minor pitch variation. All substitute parts carry RoHS or ROHS3 compliance status, supporting regulatory requirements for restricted substance elimination.

Frequently Asked Questions (FAQ)

Q: Can the 1753631 substitute for the ELFH12290 if the PCB is already designed for 5.08mm pitch?

A: No. The 1753631 operates at 0.197" (5.00mm) pitch, which differs from the ELFH12290 specification of 0.200" (5.08mm). PCB footprints designed for 5.08mm spacing will not accommodate the 5.00mm pitch without modification. This part is suitable only for designs where the footprint is specifically laid out for 5.00mm pitch spacing.

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

A: Shrouding refers to the protective housing surrounding the terminal block. 2-side shrouding (ELFH12290, 1753631) provides protection on two opposing sides, while 4-side shrouding (0395316012, 1755833) provides protection on all four sides. 4-side shrouding offers enhanced mechanical protection and reduced risk of accidental contact in high-density applications. Both configurations are electrically equivalent.

Q: Are the Phoenix Contact parts (1753631, 1755833) fully compatible with the Amphenol ELFH12290?

A: The 1755833 is fully compatible with the ELFH12290, sharing identical 5.08mm pitch, 12-position count, and vertical through-hole mounting. The 1753631 shares position count and orientation but operates at 5.00mm pitch, requiring PCB footprint compatibility verification before substitution.

Q: What is the significance of the current rating difference between the ELFH12290 (15A) and the Phoenix Contact substitutes (12A)?

A: The ELFH12290 is rated for 15A at 300V UL, while the 1753631 and 1755833 are rated for 12A at 300V UL. The lower current rating of the Phoenix Contact parts means they are suitable for applications requiring up to 12A. Applications requiring current capacity above 12A must use the ELFH12290 or the 0395316012 (Molex), both rated for 15A.

Q: Do all substitute parts meet the same RoHS compliance level?

A: The ELFH12290 is RoHS Compliant. The substitute parts 0395316012, 1753631, and 1755833 are all ROHS3 Compliant, which represents an enhanced compliance standard. ROHS3 compliance is a superset of RoHS compliance and is fully acceptable for applications requiring RoHS certification.

Q: What is the contact tail length difference, and does it affect substitutability?

A: The ELFH12290 has a contact tail length of 0.155" (3.94mm), while the Molex 0395316012 has 0.130" (3.30mm), and the Phoenix Contact parts have 0.154" (3.90mm). These variations are within acceptable tolerance for through-hole soldering and do not affect electrical substitutability. PCB hole depth and solder pad design should accommodate the specified tail length for optimal solder joint formation.
