Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1961313 is determined by the following critical parameters:

• Position Configuration: 18 positions arranged as 9 positions per level across 2 levels
• Connector Type: Header with male pins, shrouded 4-side design
• Pitch Tolerance: 2.50mm (0.098") standard spacing
• Electrical Ratings: Minimum 4A current capacity and 160V voltage rating
• Termination Method: Solder-based connection
• Mounting: Vertical through-hole PCB mounting
• Housing Material: Polyamide/Nylon construction
• Compliance: RoHS compliance requirement

The substitute part Phoenix Contact 1844947 maintains the same position configuration, connector type, and mounting orientation. While it features a slightly different pitch (2.54mm vs 2.50mm), it operates at higher electrical ratings (6A IEC, 150V UL) and represents an active product with enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844947 is an active product with current manufacturing status, whereas the 1961313 is obsolete. The 1844947 provides enhanced electrical performance with 6A current capacity compared to the 4A rating of the 1961313, while maintaining the same 160V IEC voltage specification. Both components meet RoHS compliance requirements, with the 1844947 meeting the more recent ROHS3 standard.

The primary design consideration is the pitch difference: 2.54mm (1844947) versus 2.50mm (1961313). This 0.04mm variance requires PCB layout verification to confirm mechanical compatibility with existing connector footprints. The 1844947 features gold contact mating finish compared to tin on the 1961313, providing enhanced corrosion resistance and contact reliability.

Selection of the 1844947 as a substitute is supported by its active product status, higher electrical ratings, improved contact finish, and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1844947 directly replace the 1961313 in existing designs?

A: Direct replacement requires PCB footprint verification. The pitch difference of 0.04mm (2.54mm vs 2.50mm) may affect mechanical fit depending on the connector cavity spacing. Consult PCB layout documentation to confirm compatibility before implementation.

Q: What is the significance of the contact mating finish difference?

A: The 1961313 uses tin finish, while the 1844947 uses gold finish. Gold provides superior corrosion resistance and contact reliability in high-reliability applications. This represents an improvement in the substitute part.

Q: Are both parts RoHS compliant?

A: Yes. The 1961313 is RoHS Compliant, and the 1844947 is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the electrical performance difference?

A: The 1844947 provides higher current capacity at 6A (IEC) compared to the 1961313 at 4A (IEC). Both maintain 160V (IEC) voltage rating. The substitute part offers improved electrical headroom for the same voltage specification.

Q: Why is the 1961313 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 1844947 represents the current Phoenix Contact offering in this terminal block category with equivalent functionality and enhanced specifications.

Q: Are there any packaging differences?

A: The 1961313 packaging is listed as unspecified, while the 1844947 is supplied in Bulk packaging. Confirm packaging requirements with your procurement process.
