1757682 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1757682 is a 24-position terminal block header with male pins, shrouded on four sides, designed for 90° right-angle through-hole mounting. This component operates at IEC ratings of 12A/400V and UL ratings of 15A/300V, with 5.00mm pitch spacing and tin-plated contacts. The part is active in production and RoHS compliant, making it suitable for industrial control and power distribution applications where equivalent alternatives may be required due to availability, lead time, or design flexibility considerations.

Key Parameters

Substitute Part Grouping Explanation

The On Shore Technology Inc. OSTOQ245451 qualifies as a functional substitute based on the following critical parameters:

• Position Count: Both parts feature 24 positions, maintaining identical connector density
• Pitch Compatibility: The 0.200" (5.08mm) pitch of OSTOQ245451 is mechanically compatible with 0.197" (5.00mm) pitch applications within standard PCB tolerance ranges for terminal block headers
• Connector Type: Both are male pin headers with four-side shrouding, ensuring mechanical interchangeability
• Orientation: Both feature 90° right-angle configuration for identical mounting orientation
• Termination: Both use solder termination for PCB integration
• Voltage Rating: OSTOQ245451 supports 300V UL rating, which is acceptable for applications rated at or below this voltage
• Contact Finish: Both use tin plating for equivalent contact performance
• Compliance: Both are RoHS compliant with MSL 1 rating

Parameter Comparison

Engineering Selection Recommendations

1757682 (Phoenix Contact) is the primary specification component with active product status and full IEC/UL dual certification. It is the preferred choice for applications requiring the specified 12A IEC current rating and 400V IEC voltage rating.

OSTOQ245451 (On Shore Technology) is a qualified substitute for applications operating at or below 300V UL rating. This part maintains RoHS3 compliance and provides equivalent mechanical and electrical performance within its rated parameters. The 0.08mm pitch difference (5.08mm vs. 5.00mm) is within standard PCB tolerance for terminal block header spacing and does not affect functional compatibility. The slightly longer contact tail (4.00mm vs. 4.60mm) requires verification against PCB pad depth specifications.

Both parts carry MSL 1 rating and are suitable for standard moisture-controlled storage conditions.

Frequently Asked Questions (FAQ)

Q: Can OSTOQ245451 replace 1757682 in all applications?

A: OSTOQ245451 is suitable for applications operating at 300V or below. Applications requiring the 400V IEC rating must use 1757682. The pitch difference of 0.08mm is within standard tolerance for terminal block headers but should be confirmed against specific PCB layout requirements.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The 0.08mm difference represents approximately 1.6% variance. For terminal block headers, this falls within standard PCB manufacturing tolerances and does not prevent mechanical interchangeability. However, PCB layout files should be reviewed to ensure adequate clearance.

Q: Are there differences in contact tail length that affect PCB compatibility?

A: Yes. The 1757682 has a 4.60mm contact tail, while OSTOQ245451 has a 4.00mm tail. PCB pad depth and solder joint design should accommodate the longer tail of the substitute part. This difference must be evaluated during design review.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant. The 1757682 is RoHS compliant, and OSTOQ245451 is ROHS3 compliant. Both carry MSL 1 rating and EAR99 ECCN classification. OSTOQ245451 includes REACH Unaffected status.

Q: What is the current rating difference between these parts?

A: The 1757682 specifies 12A IEC and 15A UL ratings. The OSTOQ245451 does not specify IEC current rating in the provided data. For applications requiring 12A IEC performance, the 1757682 is the specified component.
