Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1895007 is determined by the following critical parameters:

• Position Count & Configuration: 22 positions arranged as 11 per level across 2 levels
• Header Type & Shrouding: Male pins with 4-side shrouded design
• Pitch Tolerance: 0.098" (2.50mm) nominal pitch; minor pitch variations (0.100" / 2.54mm) may be acceptable depending on PCB layout constraints
• Termination Method: Solder termination required
• Mounting Style: Vertical through-hole orientation
• Electrical Ratings: Current and voltage specifications must meet or exceed application requirements
• Compliance Standards: RoHS and flammability ratings (UL94 V-0)

The Phoenix Contact 1844963 qualifies as a substitute based on matching position count, configuration, header type, shrouding, termination method, and mounting orientation. The pitch difference (2.54mm vs. 2.50mm) represents a 0.002" variance, which may require PCB layout verification for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844963 is an active production substitute for the obsolete 1895007. Both components share identical position configurations, header types, shrouding designs, termination methods, and mounting orientations. The 1844963 offers enhanced current capacity (6A vs. 4A) and improved contact mating finish (gold vs. tin), supporting superior long-term reliability and contact resistance characteristics.

The primary consideration for substitution is the pitch difference: 2.54mm (1844963) versus 2.50mm (1895007). This 0.002" variance requires PCB layout verification to confirm hole spacing compatibility. The 1844963 maintains RoHS3 compliance and UL94 V-0 flammability rating, meeting the same regulatory and safety standards as the original part.

The 1844963 is recommended for new designs and replacement applications where PCB layout accommodates the 2.54mm pitch specification.

Frequently Asked Questions (FAQ)

Q: Can the 1844963 be used as a direct replacement for the 1895007 without PCB modifications?

A: The 1844963 matches all critical functional parameters (position count, configuration, header type, shrouding, termination, and mounting orientation). However, the pitch difference (2.54mm vs. 2.50mm) requires verification that existing PCB hole spacing accommodates the substitute. If the PCB was designed for 2.50mm pitch, hole spacing may not align with the 2.54mm pitch of the 1844963.

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), voltage rating (320V IEC vs. 160V IEC), contact finish (tin vs. gold), and product status (obsolete vs. active). The 1844963 provides higher current capacity and improved contact durability through gold plating.

Q: Are both parts RoHS compliant?

A: Yes. The 1895007 is RoHS Compliant, and the 1844963 is ROHS3 Compliant. Both meet RoHS requirements for hazardous substance restrictions.

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

A: The 1895007 uses tin finish, while the 1844963 uses gold finish. Gold plating provides superior corrosion resistance and lower contact resistance over extended operational life, supporting improved long-term reliability in demanding environments.

Q: Do both parts have the same flammability rating?

A: Yes. Both the 1895007 and 1844963 carry UL94 V-0 material flammability rating, meeting identical safety standards for flame resistance.

Q: Is the 1844963 suitable for applications requiring 320V operation?

A: No. The 1844963 is rated for 160V (IEC), which is lower than the 1895007's 320V (IEC) rating. Applications requiring 320V operation must use the original 1895007 or identify alternative parts with equivalent voltage specifications.
