Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1758089 is determined by the following critical parameters:

• Position Count: Must be 9 positions
• Pitch Specification: 0.200" (5.08mm) or 0.197" (5.00mm) pitch (within tolerance for mechanical compatibility)
• Header Type: Male pins with shrouding
• Orientation: Vertical mounting configuration
• Mounting Method: Through-hole or solder mounting
• Electrical Ratings: Voltage and current ratings must meet or exceed application requirements
• Compliance: RoHS3 compliance and UL94 V-0 flammability rating where specified
• Housing Material: Polyamide (PA) or Polybutylene Terephthalate (PBT)

The identified substitute parts meet these core criteria while maintaining functional equivalence for standard terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1758089 remains the primary specification for applications requiring the exact 2-side shrouded configuration with 0.200" (5.08mm) pitch and IEC current rating of 12A at 400V. All three parts maintain Active product status and RoHS3 compliance.

Amphenol PCD ELFH09250 provides direct mechanical and electrical compatibility with identical 0.200" (5.08mm) pitch and through-hole mounting. This part offers UL94 V-0 flammability rating and supports higher UL current rating of 15A, making it suitable for applications with equivalent or higher current requirements. Housing material differs (PBT vs. Polyamide), which may affect thermal and chemical resistance characteristics depending on application environment.

On Shore Technology EDSTL955/9 offers functional equivalence with a pitch of 0.197" (5.00mm), which falls within mechanical tolerance for standard terminal block applications. This part features 4-side shrouding compared to the 2-side shrouding of the main part. Mounting method is specified as solder-based rather than through-hole. This configuration may require PCB layout modifications and is suitable for applications where solder mounting is preferred or required.

All three parts are RoHS3 compliant and maintain Active product status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol PCD ELFH09250 be used as a direct replacement for the Phoenix Contact 1758089?

A: The Amphenol PCD ELFH09250 shares identical pitch (0.200" / 5.08mm), position count (9), vertical orientation, and through-hole mounting with the Phoenix Contact 1758089. Both parts have UL94 V-0 flammability rating and tin contact mating finish. The primary differences are housing material (PBT vs. Polyamide) and shrouding configuration (4-side vs. 2-side). Mechanical and electrical compatibility is maintained for standard applications.

Q: What are the key differences between 2-side and 4-side shrouding?

A: Shrouding configuration affects mechanical protection and insertion guidance. 2-side shrouding (Phoenix Contact 1758089) provides protection on two opposing sides, while 4-side shrouding (Amphenol PCD ELFH09250 and On Shore Technology EDSTL955/9) provides protection on all four sides. 4-side shrouding offers enhanced mechanical protection and improved insertion alignment but may require different mating connector designs.

Q: Is the On Shore Technology EDSTL955/9 compatible with through-hole PCB mounting?

A: The On Shore Technology EDSTL955/9 is specified for solder mounting, not through-hole mounting. This requires different PCB design and assembly processes compared to the through-hole mounting of the Phoenix Contact 1758089 and Amphenol PCD ELFH09250. Pitch difference (0.197" vs. 0.200") is within mechanical tolerance but requires verification for specific PCB layouts.

Q: What is the significance of the pitch difference between 0.200" and 0.197"?

A: The pitch difference of 0.003" (0.076mm) between the Phoenix Contact 1758089 (0.200") and On Shore Technology EDSTL955/9 (0.197") represents a 1.5% variation. This falls within standard mechanical tolerance for terminal block applications and allows functional compatibility. However, PCB footprint verification is required to ensure proper alignment with existing connector designs.

Q: Are all three parts suitable for 300V UL applications?

A: Yes, all three parts are rated for 300V UL voltage. The Phoenix Contact 1758089 additionally supports 400V IEC voltage rating. Current ratings differ: Phoenix Contact 1758089 and On Shore Technology EDSTL955/9 support 12A, while Amphenol PCD ELFH09250 supports 15A UL current. Application voltage and current requirements must be verified against the selected part's ratings.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. The Phoenix Contact 1758089 and Amphenol PCD ELFH09250 both carry UL94 V-0 flammability rating. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for Phoenix Contact 1758089 and On Shore Technology EDSTL955/9, and Not Applicable for Amphenol PCD ELFH09250.
