Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTA022161 is determined by the following critical parameters:

• Mechanical Compatibility: Positions per level (2), pitch (7.50mm), mating orientation (horizontal with board), and mounting type (through hole) must be identical
• Electrical Compatibility: Wire gauge range (14-22 AWG) and wire termination method (screw with leaf spring and wire guard) must match
• Environmental Compliance: Operating temperature range (-30°C ~ 105°C), RoHS3 compliance, and REACH unaffected status must be maintained
• Fastener Specifications: Screw thread (M3) must be consistent

The ED110/2DS meets all mechanical and electrical compatibility criteria. While it features higher current (20 A) and voltage (300 V) ratings compared to the OSTTA022161, these represent enhanced performance capabilities that do not compromise backward compatibility in applications designed for the original part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTA022161 and ED110/2DS maintain Active product status, ensuring continued manufacturer support and supply chain availability. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial applications.

The ED110/2DS provides enhanced electrical performance with 20 A current capacity and 300 V voltage rating, compared to the OSTTA022161's 16 A and 250 V specifications. This higher rating capability makes the ED110/2DS suitable for applications requiring greater electrical headroom while maintaining full mechanical and environmental compatibility.

Selection between these parts should be based on application-specific current and voltage requirements. The OSTTA022161 remains appropriate for designs rated at or below 16 A and 250 V. The ED110/2DS is the preferred choice for new designs or applications requiring the enhanced electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can ED110/2DS be used as a direct replacement for OSTTA022161 in existing designs?

A: Yes. The ED110/2DS is mechanically and electrically compatible with the OSTTA022161. Both components share identical pitch (7.50mm), position count (2), mounting type (through hole), wire gauge range (14-22 AWG), and screw specifications (M3). The higher current and voltage ratings of the ED110/2DS do not create compatibility issues in applications designed for the original part.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (ED110/2DS: 20 A vs. OSTTA022161: 16 A) and voltage rating (ED110/2DS: 300 V vs. OSTTA022161: 250 V). Housing material differs slightly (ED110/2DS uses polyamide/nylon vs. OSTTA022161 thermoplastic), and screw torque specification is higher for ED110/2DS (0.5 Nm vs. 0.4 Nm). All other electrical, mechanical, and environmental parameters are equivalent.

Q: Are both parts available in the same packaging format?

A: Yes. Both the OSTTA022161 and ED110/2DS are supplied in bulk packaging, consistent with standard terminal block distribution methods.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations applicable to electronic components.

Q: What wire gauges are supported by both parts?

A: Both the OSTTA022161 and ED110/2DS accept wire gauges from 14 AWG to 22 AWG, providing compatibility across standard industrial wiring specifications.
