Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1757462 is determined by the following critical parameters:

• Electrical Compatibility: Voltage rating (minimum 300 V UL), current capacity (minimum 15 A UL), and contact mating finish (tin)
• Mechanical Compatibility: 24-position configuration, 0.200" (5.08mm) pitch, 90° right-angle orientation, male pins with four-side shrouding
• Termination and Mounting: Through-hole or solder mounting capability
• Regulatory Compliance: ROHS3 compliance, REACH unaffected status, and flammability rating (UL94 V-0 or equivalent)
• Physical Dimensions: Contact tail length and insulation height must accommodate PCB layout requirements

The On Shore Technology Inc. OSTOQ245451 qualifies as a substitute based on matching position count, pitch, orientation, shrouding configuration, tin contact finish, voltage rating (300 V UL), ROHS3 compliance, and REACH unaffected status. Differences in mounting type (solder vs. through-hole), housing material (thermoplastic vs. polyamide), and physical dimensions are noted for application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1757462 and On Shore Technology OSTOQ245451 maintain active product status and meet ROHS3 compliance and REACH unaffected requirements, ensuring regulatory alignment for current and future applications.

The Phoenix Contact 1757462 is specified for through-hole mounting with a 12A IEC current rating and 400V IEC voltage rating, providing higher electrical performance margins under IEC standards. The UL ratings (15A, 300V) are shared with the substitute part.

The On Shore Technology OSTOQ245451 is configured for solder mounting and provides an operating temperature range of -40°C to 115°C. Physical dimensions differ: the OSTOQ245451 has a longer contact tail length (0.157" vs. 0.138") and reduced insulation height (0.157" vs. 0.339"), which may affect PCB layout compatibility and clearance requirements.

Selection between these parts depends on mounting method requirements (through-hole vs. solder), PCB space constraints, and thermal operating conditions. Both parts satisfy the core electrical and compliance criteria for equivalent functionality.

Frequently Asked Questions (FAQ)

Q: What determines if the On Shore Technology OSTOQ245451 can replace the Phoenix Contact 1757462?

A: Substitution is based on matching electrical ratings (300V UL, tin contact finish), mechanical configuration (24 positions, 0.200" pitch, 90° right-angle, four-side shrouding, male pins), and regulatory compliance (ROHS3, REACH unaffected). The primary difference is mounting type: the Phoenix Contact uses through-hole mounting while the On Shore Technology part uses solder mounting.

Q: Are there differences in current rating between these parts?

A: The Phoenix Contact 1757462 specifies 15A under UL standards and 12A under IEC standards. The On Shore Technology OSTOQ245451 does not provide a specified current rating in the available data. Both parts meet the 300V UL voltage requirement.

Q: How do the physical dimensions affect compatibility?

A: The Phoenix Contact 1757462 has a contact tail length of 0.138" (4.60mm) and insulation height of 0.339" (8.61mm). The On Shore Technology OSTOQ245451 has a contact tail length of 0.157" (4.00mm) and insulation height of 0.157" (4.00mm). These differences may impact PCB layout, component spacing, and clearance requirements. Verify dimensions against your specific PCB design before substitution.

Q: What is the difference between through-hole and solder mounting?

A: Through-hole mounting (Phoenix Contact 1757462) uses pins inserted into PCB holes and soldered from the reverse side. Solder mounting (On Shore Technology OSTOQ245451) involves direct soldering of the component to the PCB surface. These mounting methods require different PCB pad designs and assembly processes.

Q: Do both parts meet environmental and compliance standards?

A: Yes. Both the Phoenix Contact 1757462 and On Shore Technology OSTOQ245451 are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity levels. The Phoenix Contact part specifies UL94 V-0 flammability rating; the On Shore Technology part does not provide this specification in the available data.

Q: What is the operating temperature range for each part?

A: The Phoenix Contact 1757462 does not specify an operating temperature range in the available data. The On Shore Technology OSTOQ245451 operates from -40°C to 115°C. Verify temperature requirements for your application before selecting a substitute.
