EDSTL955/18 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The EDSTL955/18 is an 18-position terminal block header manufactured by On Shore Technology Inc., designed for vertical solder mounting applications. This component features male pins with 4-side shrouding and a 0.197" (5.00mm) pitch configuration. The part is currently active in production with 980 units in stock. Alternative equivalent parts may be required due to supply chain considerations, application-specific mounting requirements, or design revisions that necessitate through-hole mounting instead of solder mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTL955/18 is determined by the following critical parameters:

• Position Count & Pitch: 18 positions at 0.197" (5.00mm) spacing (non-negotiable)
• Header Type: Male pins with 4-side shrouding (non-negotiable)
• Orientation: Vertical configuration (non-negotiable)
• Voltage Rating: Minimum 300 V UL compliance (non-negotiable)
• Housing Material: Polyamide (PA) or Nylon (non-negotiable)
• Mounting Compatibility: Solder or through-hole mounting acceptable for PCB integration
• Regulatory Compliance: ROHS3 compliant, REACH unaffected status

The Phoenix Contact 1755668 qualifies as an equivalent substitute based on matching all critical parameters. While this part utilizes through-hole mounting instead of solder mounting, both termination methods provide equivalent electrical and mechanical connectivity for the 18-position configuration. The substitute maintains identical pitch, position count, shrouding design, and voltage rating.

Parameter Comparison

Engineering Selection Recommendations

Both the EDSTL955/18 and 1755668 are active production components with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current applications. Selection between these parts depends on PCB design requirements:

• EDSTL955/18: Select for designs requiring solder-mount termination with surface-level integration
• 1755668: Select for designs requiring through-hole mounting with mechanical reinforcement on the PCB

The 1755668 provides additional current rating specification (12 A) and material flammability rating (UL94 V-0), which may be advantageous for applications requiring enhanced electrical performance documentation or flame-resistance certification. Both parts maintain identical electrical connectivity and mechanical footprint compatibility at the 18-position, 5.00mm pitch configuration.

Frequently Asked Questions (FAQ)

Q: Can the 1755668 directly replace the EDSTL955/18 in existing designs?

A: Direct replacement requires PCB redesign. The EDSTL955/18 uses solder mounting, while the 1755668 uses through-hole mounting. Both provide equivalent electrical performance at 18 positions and 5.00mm pitch, but PCB layout and trace routing must be modified to accommodate the different mounting method.

Q: Are there any electrical performance differences between these parts?

A: Both parts meet 300 V UL voltage requirements and maintain identical pitch and position configuration. The 1755668 specifies 12 A current rating and UL94 V-0 flammability rating, whereas the EDSTL955/18 does not provide these specifications. For applications requiring current or flammability documentation, the 1755668 offers more complete electrical characterization.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the EDSTL955/18 and 1755668 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the significance of the different insulation heights?

A: The EDSTL955/18 has an insulation height of 0.154" (3.90mm), while the 1755668 has 0.472" (12.00mm). This difference reflects the through-hole mounting design of the 1755668, which requires additional insulation clearance above the PCB surface. This parameter is critical for PCB layout and component spacing calculations.

Q: Are both parts available in the same packaging?

A: Both parts are supplied in bulk packaging. Current inventory shows 980 units of EDSTL955/18 and 953 units of 1755668 in stock.
