Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1937570 has one identified equivalent substitute: part number 1788660. Substitution eligibility is determined by the following critical parameters that must remain constant:

• Number of Positions: 10
• Pitch: 0.138" (4.6mm)
• Header Orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Termination Style: Solder
• Mounting Type: Through Hole
• Current Rating - IEC: 8A per Position
• Voltage Rating - IEC: 250V
• Current Rating - UL: 8A
• Voltage Rating - UL: 300V
• Contact Mating Finish: Tin
• Material Flammability Rating: UL94 V-0

The substitute part 1788660 maintains all critical electrical and mechanical parameters, ensuring functional compatibility in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1788660 is the direct active equivalent for the obsolete 1937570. Both components maintain identical electrical specifications (8A IEC, 250V IEC, 8A UL, 300V UL) and mechanical form factors (10 positions, 4.6mm pitch, 90° right-angle, through-hole solder termination).

Key differences exist in housing material composition and physical dimensions. The 1788660 uses Liquid Crystal Polymer (LCP) housing versus the polyamide glass-filled nylon of the 1937570, with corresponding reductions in contact tail length (0.102" vs. 0.134") and insulation height (0.272" vs. 0.285"). The 1788660 also provides superior moisture handling with MSL 1 rating versus MSL 3.

The 1788660 carries active product status with RoHS compliance, ensuring long-term availability and regulatory alignment for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the 1788660 directly replace the 1937570 in existing designs?

A: Yes. Both components share identical electrical ratings (8A IEC, 250V IEC, 8A UL, 300V UL), pitch (4.6mm), position count (10), orientation (90° right-angle), and termination method (solder through-hole). Physical dimension variations (contact tail length and insulation height) are minor and do not affect functional compatibility in standard PCB layouts.

Q: What is the primary reason for substitution?

A: The 1937570 is classified as obsolete. The 1788660 is the active equivalent from Phoenix Contact, ensuring procurement availability and compliance with current manufacturing standards.

Q: Are there compliance differences between the two parts?

A: Both parts meet UL94 V-0 flammability requirements. The 1788660 carries RoHS compliance with MSL 1 rating, providing enhanced moisture resistance compared to the 1937570's MSL 3 rating. Both are suitable for industrial control applications.

Q: Does the housing material change affect electrical performance?

A: No. The shift from polyamide glass-filled nylon to Liquid Crystal Polymer (LCP) in the 1788660 maintains electrical specifications while improving material properties. Both materials support the rated 8A per position and 250V (IEC) / 300V (UL) specifications.

Q: What packaging is available for the 1788660?

A: The 1788660 is supplied in bulk packaging, with 1058 pieces currently in stock as new original inventory.
