Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1961342 is determined by the following critical parameters:

• Position Count & Configuration: 24 positions arranged in 2 levels of 12 positions each
• Connector Type & Shrouding: Header with male pins and 4-side shrouded design
• Pitch Tolerance: 2.5mm pitch (0.098") is the primary mechanical constraint
• Electrical Ratings: Minimum 4A current capacity and 160V voltage rating
• Termination Method: Solder termination for PCB integration
• Mounting Style: Vertical through-hole configuration
• Housing Material: Polyamide (PA) or equivalent dielectric material

The substitute part Phoenix Contact 1844976 shares the same position count, connector type, shrouding, header orientation, termination method, and mounting style. However, it operates at a different pitch (2.54mm vs. 2.50mm), which represents a mechanical incompatibility for direct PCB footprint substitution. The substitute also provides enhanced electrical ratings (6A vs. 4A) and improved contact finish (gold vs. tin), along with active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844976 is an active product with current manufacturing support and ROHS3 compliance, whereas the 1961342 is obsolete. The 1844976 provides superior electrical performance with 6A current capacity versus 4A, and gold contact finish for improved corrosion resistance compared to tin plating.

The critical consideration for substitution is the pitch difference: 2.50mm (1961342) versus 2.54mm (1844976). This 0.04mm variance represents a mechanical incompatibility for direct PCB footprint replacement. Applications requiring the exact 2.50mm pitch spacing cannot use the 1844976 without PCB redesign. Conversely, applications with 2.54mm pitch PCB layouts can adopt the 1844976 as a direct substitute with the added benefits of active product status and enhanced electrical ratings.

Both parts maintain identical position counts, connector type, shrouding configuration, and solder termination method, ensuring functional equivalence within their respective pitch specifications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1844976 replace the 1961342 directly on existing PCBs?

A: Direct PCB replacement is not possible due to pitch incompatibility. The 1961342 uses 2.50mm pitch while the 1844976 uses 2.54mm pitch. PCB footprints designed for one pitch will not accommodate the other without layout modification.

Q: What are the key differences between these two parts?

A: The primary differences are pitch (2.50mm vs. 2.54mm), current rating (4A vs. 6A), contact finish (tin vs. gold), and product status (obsolete vs. active). Both share identical position counts, connector type, and mounting configuration.

Q: Is the 1844976 electrically compatible with the 1961342 specifications?

A: Yes, the 1844976 exceeds the electrical requirements of the 1961342. It provides 6A capacity versus 4A, and maintains the 160V voltage rating. The gold contact finish offers improved reliability compared to tin plating.

Q: Why would I choose the 1844976 over the 1961342?

A: The 1844976 is the preferred choice for new designs and ongoing production due to its active product status, ROHS3 compliance, enhanced electrical ratings, and superior contact finish. The 1961342 should only be used for legacy system maintenance where pitch-specific PCB compatibility is required.

Q: Are there any compliance differences between these parts?

A: The 1961342 is RoHS Compliant, while the 1844976 is ROHS3 Compliant, representing a more current regulatory standard. Both parts carry EAR99 ECCN classification and identical HTSUS codes.

Q: What is the impact of the contact finish difference?

A: The 1844976 uses gold plating for superior corrosion resistance and contact reliability, while the 1961342 uses tin plating. Gold finish is preferred for applications requiring extended service life and harsh environmental conditions.
