ED110/7DS Terminal Block - Equivalent & Substitute Parts

Part Overview

The ED110/7DS is a 7-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with 7.5mm pitch spacing. This active product provides screw-based wire termination with leaf spring and wire guard features, supporting 20A at 300V across a wide operating temperature range of -30°C to 105°C. Alternative equivalent parts may be required due to supply chain considerations, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ED110/7DS is determined by strict alignment with the following critical parameters:

• Position count and pitch: 7 positions at 0.295" (7.5mm) spacing
• Electrical ratings: 20A current and 300V voltage minimum
• Mounting configuration: Through-hole PCB mounting with horizontal board orientation
• Termination method: Screw-based with leaf spring and wire guard
• Mechanical interface: M3 screw thread for consistent torque application
• Environmental compliance: RoHS compliance and MSL 1 rating

The substitute part 1988150 (Phoenix Contact COMBICON PT series) meets all critical substitution criteria. Both parts share identical position count, pitch, electrical ratings, mounting type, termination method, and screw specifications. Variations in wire gauge acceptance (ED110/7DS: 14-22 AWG; 1988150: 12-20 AWG) and torque specification range (ED110/7DS: 0.5 Nm fixed; 1988150: 0.45-0.5 Nm range) remain within acceptable engineering tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the ED110/7DS and 1988150 maintain active product status with full RoHS compliance and MSL 1 rating, ensuring long-term availability and environmental regulatory alignment. Selection between these parts should be based on supply chain availability, lead time requirements, and regional sourcing preferences. The ED110/7DS offers established On Shore Technology supply channels, while the 1988150 provides Phoenix Contact COMBICON PT series availability. Both parts satisfy identical electrical performance requirements and mechanical interface specifications for direct substitution in 7-position, 7.5mm pitch terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the 1988150 directly replace the ED110/7DS in existing designs?

A: Yes. Both parts share identical position count (7), pitch (7.5mm), electrical ratings (20A/300V), mounting type (through-hole), termination method (screw with leaf spring and wire guard), and screw thread specification (M3). PCB footprints and connector interfaces are mechanically compatible.

Q: What is the significance of the wire gauge difference between these parts?

A: The ED110/7DS accepts 14-22 AWG wire, while the 1988150 accepts 12-20 AWG wire. The 1988150 accommodates larger gauge conductors (12 AWG) but has a narrower upper limit (20 AWG vs. 22 AWG). For applications using 14-20 AWG wire, both parts are fully compatible. Applications requiring 12 AWG or 22 AWG wire must use the respective part designed for that gauge range.

Q: How do the torque specifications differ?

A: The ED110/7DS specifies a fixed torque of 0.5 Nm (4.4 Lb-In), while the 1988150 allows a range of 0.45-0.5 Nm (3.9-4.4 Lb-In). The 1988150's range encompasses the ED110/7DS specification, ensuring consistent clamping force when applying 0.5 Nm torque to either part.

Q: Are both parts RoHS compliant?

A: Yes. The ED110/7DS is ROHS3 compliant, and the 1988150 is RoHS compliant. Both meet current environmental regulatory requirements for electronic component manufacturing and use.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage, handling, or reflow conditions, simplifying supply chain management and assembly processes.

Q: Can these parts be used interchangeably in new designs?

A: Yes. Both parts meet identical functional and mechanical requirements for 7-position, 7.5mm pitch wire-to-board terminal block applications. Design selection can be based on preferred manufacturer, supply availability, or regional sourcing strategy without requiring design modifications.
