Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELFH08290 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Compatibility Criteria:

• Number of positions: 8 (exact match required)
• Header type: Male pins, shrouded (2 side) configuration
• Mounting method: Vertical through-hole
• Termination: Solder connection
• Pitch tolerance: 5.00mm to 5.08mm (within standard manufacturing tolerance)
• Electrical ratings: Minimum 12A current and 300V voltage (UL standards)
• Flammability: UL94 V-0 material classification
• RoHS compliance status

Substitute Parts Identified:

• 1753550 (Phoenix Contact COMBICON MSTBV series, 5.00mm pitch)
• 1758076 (Phoenix Contact COMBICON MSTBV series, 5.08mm pitch)

Both substitutes meet the core functional requirements for 8-position vertical terminal block header applications with equivalent shrouded male pin configurations and solder termination.

Parameter Comparison

Engineering Selection Recommendations

1753550 (Phoenix Contact, 5.00mm Pitch)

This substitute is suitable for applications where pitch tolerance of ±0.08mm from the nominal 5.08mm specification is acceptable. The 5.00mm pitch variant maintains 8-position configuration with identical shrouded male pin design and solder termination. Current rating of 12A meets minimum requirements for most industrial applications, though designs requiring the full 15A capacity of the ELFH08290 should verify load distribution. Both parts carry UL94 V-0 flammability certification and active product status. ROHS3 compliance provides enhanced regulatory coverage compared to standard RoHS. Contact tail length and insulation height remain within 0.04mm tolerance, ensuring PCB footprint compatibility for most standard designs.

1758076 (Phoenix Contact, 5.08mm Pitch)

This substitute provides exact pitch matching at 0.200" (5.08mm), eliminating tolerance considerations for PCB layout. The COMBICON MSTBV series maintains identical 8-position vertical through-hole configuration with male pins and shrouded design. Current rating of 12A and voltage rating of 300V (UL) satisfy standard industrial control applications. Contact tail length of 0.154" (3.90mm) and insulation height of 0.472" (12.00mm) are within 0.01mm of the ELFH08290 specifications. ROHS3 compliance and active product status confirm regulatory alignment. This variant is recommended for direct replacement in existing designs without PCB modification.

Both Phoenix Contact substitutes maintain UL94 V-0 material classification, tin contact finish, and through-hole solder termination, ensuring compatibility with standard assembly processes and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can 1753550 be used as a direct replacement for ELFH08290 on existing PCBs?

A: The 1753550 operates at 5.00mm pitch versus the ELFH08290 at 5.08mm pitch, representing a 0.08mm difference. This tolerance may require PCB layout verification depending on design margins. For new designs or where PCB modification is feasible, this part is functionally equivalent. For existing PCBs with fixed footprints, 1758076 is the preferred substitute due to exact pitch matching.

Q: What is the current rating difference between ELFH08290 and the Phoenix Contact substitutes?

A: The ELFH08290 is rated at 15A (UL), while both Phoenix Contact substitutes (1753550 and 1758076) are rated at 12A (UL). Applications requiring the full 15A capacity should confirm that actual circuit loads do not exceed 12A, or consider alternative components. For standard industrial control applications operating below 12A, both substitutes are suitable.

Q: Are the mechanical dimensions compatible between these parts?

A: Contact tail length and insulation height are within 0.04mm tolerance across all three parts. The primary dimensional difference is pitch spacing (5.00mm vs. 5.08mm). For applications with fixed connector interfaces or PCB footprints, verify pitch compatibility before selection. The 1758076 with exact 5.08mm pitch matching is recommended for retrofit applications.

Q: Do all three parts meet the same regulatory standards?

A: All three parts carry UL94 V-0 flammability certification and EAR99 export classification. The ELFH08290 is RoHS Compliant, while both Phoenix Contact substitutes are ROHS3 Compliant, providing enhanced regulatory coverage. All parts share identical HTSUS classification (8536.69.4040). For applications requiring specific RoHS revision compliance, confirm requirements with design documentation.

Q: What is the difference between 1753550 and 1758076?

A: Both are Phoenix Contact COMBICON MSTBV series parts with identical electrical ratings (12A, 300V UL) and mechanical configuration. The sole difference is pitch: 1753550 operates at 5.00mm while 1758076 operates at 5.08mm. Select 1758076 for exact pitch matching with ELFH08290 designs, or 1753550 if pitch tolerance is acceptable and supply availability is a factor.

Q: Can these parts be used interchangeably in the same assembly?

A: No. Once a design is committed to a specific pitch (5.00mm or 5.08mm), all connector positions must use the same pitch variant. Mixing pitch specifications within a single assembly will result in misalignment and connection failure. Confirm pitch specification in design documentation before component selection.
