Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1710939 terminal block header is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed IEC 12A/630V and UL 15A/300V specifications
• Physical Compatibility: 3-position configuration, 0.300" (7.62mm) pitch, 90° right-angle orientation, and through-hole mounting type
• Connector Type: Male pins with 4-side shrouded design
• Termination Method: Solder termination
• Material and Safety: Polyamide housing with UL94 V-0 flammability rating
• Regulatory Compliance: RoHS compliance status

The Phoenix Contact 1710939 has one identified substitute: the Phoenix Contact 1812872 from the COMBICON GMSTBA series. This substitute meets all critical physical and electrical compatibility parameters while offering enhanced electrical ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1812872 is a direct substitute for the obsolete 1710939 terminal block header. The 1812872 maintains identical physical dimensions and connector configuration while providing superior electrical performance with increased current capacity (16A IEC vs. 12A IEC) and voltage rating (1 kV IEC vs. 630V IEC). Both components maintain UL94 V-0 flammability compliance and RoHS compliance status.

The primary advantage of selecting the 1812872 is its active product status, ensuring long-term availability and supply chain continuity. The minor reduction in contact tail length (0.126" vs. 0.138") and the addition of a locking ramp feature in the 1812872 represent design improvements in the COMBICON GMSTBA series. The identical insulation height of 0.339" (8.61mm) confirms mechanical compatibility with existing PCB layouts and mating connectors.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1812872 be used as a direct replacement for the 1710939 in existing designs?

A: Yes. The 1812872 maintains the same 3-position configuration, 0.300" (7.62mm) pitch, 90° right-angle orientation, through-hole mounting, and solder termination. The identical insulation height ensures compatibility with existing PCB footprints and mating connectors. The enhanced electrical ratings of the 1812872 provide additional design margin.

Q: What is the difference in contact tail length between these parts?

A: The 1710939 has a contact tail length of 0.138" (4.60mm), while the 1812872 has 0.126" (3.20mm). This 0.012" (0.30mm) difference is within typical PCB design tolerances and does not affect functional compatibility for standard through-hole soldering applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1710939 and 1812872 are RoHS compliant and carry UL94 V-0 flammability ratings, meeting current regulatory requirements for electronic component manufacturing.

Q: What does the locking ramp feature in the 1812872 provide?

A: The locking ramp is a mechanical feature in the COMBICON GMSTBA series that enhances connector retention and stability during mating operations. This represents a design improvement over the mating and mounting flange feature in the original 1710939.

Q: Why is the 1710939 classified as obsolete?

A: The 1710939 has been superseded by the 1812872 in the Phoenix Contact product line. The 1812872 offers improved electrical ratings and active manufacturing status, making it the recommended choice for new designs and ongoing system maintenance.
