Key Parameters

Substitute Part Grouping Explanation

The On Shore Technology Inc. OSTTJ167150 qualifies as an equivalent substitute based on the following critical parameters:

• Identical Position Count & Pitch: Both parts feature 16 positions at 0.197" (5.00mm) pitch, ensuring mechanical and electrical compatibility with mating connectors
• Matching Socket Type: Both are female socket plugs with free-hanging (in-line) mounting orientation
• Compatible Wire Gauge Range: Both accept 12-30 AWG conductors, with overlapping mm² range (0.2-2.5mm² vs. 0.34-2.5mm²)
• Equivalent Voltage Rating: Both rated at 300V (UL), meeting standard industrial control applications
• Identical Flammability Rating: Both comply with UL94 V-0 material standards
• Regulatory Alignment: Both are ROHS3 compliant and REACH unaffected

The OSTTJ167150 operates within the same electrical envelope and physical form factor, making it suitable for direct substitution in applications where the Phoenix Contact 1779974 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1779974 and On Shore Technology OSTTJ167150 are active production components with equivalent regulatory compliance profiles. Selection between these parts should be based on:

• Supply Availability: Phoenix Contact 1779974 has 1025 units in stock; OSTTJ167150 has 1658 units available
• Regulatory Compliance: Both meet ROHS3 and REACH requirements, suitable for EU and international markets
• Certification Alignment: Both comply with UL94 V-0 flammability standards for industrial control environments
• Torque Specification: OSTTJ167150 torque (0.56 Nm) falls within the Phoenix Contact specification range (0.5-0.6 Nm), ensuring consistent installation practices
• Wire Gauge Compatibility: Both support the full 12-30 AWG range required for standard industrial applications

No additional testing or verification is required when substituting between these parts in applications where the original specification is met.

Frequently Asked Questions (FAQ)

Q: Can the On Shore Technology OSTTJ167150 directly replace the Phoenix Contact 1779974 in existing designs?

A: Yes. Both parts share identical position count (16), pitch (5.00mm), socket type (female), mounting configuration (free-hanging in-line), and voltage rating (300V UL). The OSTTJ167150 meets all electrical and mechanical requirements for direct substitution.

Q: Are there any wire gauge limitations when using the OSTTJ167150 substitute?

A: No. The OSTTJ167150 accepts 12-30 AWG (0.34-2.5mm²), which covers the full range of the original Phoenix Contact specification for practical industrial applications. The 0.2mm² lower limit of the Phoenix Contact is not affected.

Q: Do both parts require the same screw torque during installation?

A: The OSTTJ167150 specifies 0.56 Nm (5.0 Lb-In), which is within the Phoenix Contact range of 0.5-0.6 Nm. Installation procedures remain consistent between both parts.

Q: What is the wire strip length difference between these parts?

A: Phoenix Contact 1779974 specifies 7mm; OSTTJ167150 specifies 7-8mm. This minor variation does not affect compatibility or installation in standard applications.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the Phoenix Contact 1779974 and OSTTJ167150 are ROHS3 compliant and REACH unaffected, meeting current EU and international environmental standards.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain requirements and inventory availability. Both parts are active production components with equivalent performance characteristics. The OSTTJ167150 currently has higher inventory availability (1658 units vs. 1025 units).
