Phoenix Contact 1961290 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1961290 is a 14-position terminal block header with male pins, featuring a shrouded 4-side design and 2.50mm pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement planning. The part operates at 4A (IEC) and 160V (IEC), with solder termination and tin contact mating finish.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1961290 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 14
• Positions per level: 7
• Number of levels: 2
• Header orientation: Vertical
• Termination style: Solder
• Mounting type: Through hole
• Type: Header with male pins, shrouded (4 side)
• Voltage rating: 160V (IEC) or higher
• Housing material: Polyamide (PA), Nylon

Allowable Variation Parameters:

• Pitch: 2.50mm (0.098") to 2.54mm (0.100") — minor pitch tolerance acceptable for through-hole applications
• Current rating: 4A (IEC) minimum; higher ratings acceptable
• Contact mating finish: Tin or gold plating acceptable
• Product status: Active preferred over obsolete for long-term availability

The Phoenix Contact 1844921 qualifies as a substitute based on these criteria, with the primary difference being a 0.04mm pitch increase (2.54mm vs. 2.50mm) and enhanced electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844921 is the identified substitute for the obsolete 1961290 based on functional equivalence and enhanced specifications. Selection should consider the following factors:

Product Status: The 1844921 carries active product status, ensuring continued availability and manufacturing support. The 1961290 is obsolete, limiting future procurement options.

Compliance & Certifications: Both parts are RoHS compliant. The 1844921 meets ROHS3 requirements and maintains REACH unaffected status, providing superior regulatory alignment for current applications.

Electrical Performance: The 1844921 provides higher current capacity (6A IEC vs. 4A IEC) and equivalent voltage rating (160V IEC). This represents an improvement in electrical headroom without compromising compatibility.

Pitch Consideration: The 0.04mm pitch increase (2.54mm vs. 2.50mm) is within acceptable tolerance for through-hole PCB layouts. PCB redesign may be required if the original layout was designed with minimal spacing margins.

Contact Finish: The gold plating on the 1844921 provides enhanced corrosion resistance compared to tin finish, improving long-term reliability in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the 1844921 be used as a direct replacement for the 1961290 without PCB modification?

A: The 1844921 is functionally equivalent but features a 0.04mm pitch increase (2.54mm vs. 2.50mm). Direct PCB compatibility depends on the original layout design. If the PCB was designed with standard 2.54mm grid spacing, the 1844921 will mount directly. If the PCB was designed specifically for 2.50mm pitch with minimal spacing, PCB modification may be necessary.

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

A: The primary differences are: (1) pitch specification (2.50mm vs. 2.54mm), (2) current rating (4A vs. 6A IEC), (3) contact finish (tin vs. gold), (4) product status (obsolete vs. active), and (5) RoHS compliance level (RoHS vs. ROHS3).

Q: Is the higher current rating of the 1844921 a concern for applications designed for 4A?

A: No. Higher current ratings indicate improved electrical capacity and do not create compatibility issues for lower-current applications. The 1844921 will safely operate at 4A and below.

Q: Does the gold plating on the 1844921 affect compatibility?

A: No. Gold plating is a superior contact finish that enhances corrosion resistance and contact reliability. It is fully compatible with solder termination and does not introduce compatibility issues.

Q: What packaging format is available for the 1844921?

A: The 1844921 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Are there any mechanical dimension differences that would affect mounting?

A: The contact tail length and insulation height specifications are not provided for the 1844921. Verify mechanical compatibility with the original PCB design before implementation, particularly if the original layout has tight spacing constraints.
