Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1961300 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 16-position terminal block header configuration
• Male pins with 4-side shrouded design
• Vertical through-hole mounting orientation
• Solder termination method
• Polyamide housing material
• Electrical ratings meeting or exceeding IEC specifications (4A minimum, 160V minimum)

Secondary Compatibility Factors:

• Pitch tolerance (2.50mm primary, 2.54mm acceptable with PCB redesign consideration)
• Contact tail length and insulation height within mechanical envelope constraints
• RoHS compliance status
• Contact mating finish (tin or gold acceptable)

The substitute part Phoenix Contact 1844934 meets these criteria with the following distinction: it operates at higher current capacity (6A IEC) and uses 2.54mm pitch with gold-plated contacts, representing an active product with enhanced electrical performance characteristics.

Engineering Selection Recommendations

For Direct Replacement (Same Pitch - 2.50mm): No active substitute with identical 2.50mm pitch is available in the provided data. The 1961300 remains the only option for applications requiring exact 2.50mm pitch spacing without PCB modification.

For Functional Substitution (2.54mm Pitch): Phoenix Contact 1844934 serves as a functional substitute when PCB layout permits 2.54mm pitch accommodation. This part is active in production, ensuring long-term availability and supply chain stability. The 1844934 provides enhanced electrical performance (6A IEC vs. 4A IEC) and gold-plated contacts, which offer superior corrosion resistance compared to tin plating. Both parts maintain RoHS compliance and identical mechanical configuration (16 positions, 2 levels, 8 positions per level, vertical orientation, solder termination).

Compliance Considerations: Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, ensuring regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can the 1844934 directly replace the 1961300 without PCB modification? A: No. The pitch difference (2.54mm vs. 2.50mm) requires PCB layout adjustment. Direct mechanical substitution is not possible without redesign.

Q: What is the significance of the pitch difference between these parts? A: Pitch determines the center-to-center spacing of connector positions. A 0.02" (0.50mm) difference affects PCB footprint design. The 1844934 uses standard 2.54mm pitch (0.100"), while the 1961300 uses 2.50mm pitch (0.098").

Q: Are there electrical performance differences between these parts? A: Yes. The 1844934 supports 6A (IEC) compared to the 1961300's 4A (IEC). Both maintain 160V (IEC) rating. The 1844934 also provides UL ratings (6A, 150V), whereas the 1961300 does not specify UL compliance.

Q: What is the advantage of gold-plated contacts on the 1844934? A: Gold plating provides enhanced corrosion resistance and improved contact reliability in high-humidity or corrosive environments compared to tin plating. This is particularly relevant for long-term reliability in demanding applications.

Q: Why is the 1961300 classified as obsolete? A: Obsolete status indicates Phoenix Contact has discontinued production. The 1844934 represents the active product line successor, offering improved specifications and ongoing manufacturing support.

Q: Are both parts RoHS compliant? A: Yes. Both the 1961300 and 1844934 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What packaging options are available? A: The 1961300 packaging is not specified in available data. The 1844934 is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes.
