Phoenix Contact 1955646 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1955646 is a 3-position terminal block header with male pins, shrouded on 4 sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component belongs to the COMBICON CCV series and is classified as active product status. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits cross-manufacturer compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1955646 is determined by the following critical parameters:

• Electrical Compatibility: Voltage and current ratings must meet or exceed the application requirements. The main part specifies 12A IEC / 10A UL at 400V IEC / 300V UL. Substitute parts must support minimum 300V UL and 10A UL ratings.
• Mechanical Compatibility: 3-position configuration, 0.200" (5.08mm) pitch, vertical orientation, through-hole mounting, and shrouded 4-side design are mandatory.
• Termination Method: Solder termination is required.
• Flammability & Compliance: UL94 V-0 material rating and RoHS compliance are baseline requirements.
• Physical Dimensions: Insulation height of 0.472" (12.00mm) must be maintained for PCB clearance and mating compatibility.

The identified substitute parts (Molex 0395350003 and TE Connectivity 796867-3) meet these core substitution criteria while maintaining functional equivalence within the terminal block header category.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1955646 remains the primary specification when supply is available. This part is active product status with RoHS compliance and MSL 1 rating, suitable for standard industrial applications.

Molex 0395350003 qualifies as a direct substitute. It maintains identical pitch, position count, orientation, and insulation height. The UL current rating of 15A exceeds the main part's 10A specification, providing margin for application requirements. Housing material differs (PA66 vs. LCP), but both materials meet UL94 V-0 flammability requirements. Contact tail length is longer (0.150" vs. 0.102"), requiring verification of PCB pad layout compatibility. ROHS3 compliance status indicates enhanced regulatory alignment. This part is active product status with confirmed inventory availability.

TE Connectivity 796867-3 qualifies as a direct substitute. It maintains identical pitch, position count, orientation, and insulation height. The UL current rating of 15A exceeds the main part's 10A specification. Housing material is PA66 (identical to Molex substitute), meeting UL94 V-0 requirements. Contact tail length is 0.138", intermediate between the main part and Molex substitute, requiring PCB pad layout verification. Color is green rather than black, which may impact visual identification in assembly. RoHS compliance and MSL 1 rating are confirmed. This part is active product status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can Molex 0395350003 and TE Connectivity 796867-3 be used interchangeably with Phoenix Contact 1955646?

A: Both substitute parts meet the core electrical and mechanical parameters: 3-position, 0.200" pitch, vertical through-hole, shrouded 4-side design, 300V UL / 10A UL minimum ratings, UL94 V-0 flammability, and 0.472" insulation height. However, contact tail length differences (0.102" main part vs. 0.150" Molex vs. 0.138" TE) require PCB pad layout verification before substitution. Housing material differs (LCP vs. PA66), which may affect thermal or mechanical performance in specific applications.

Q: What are the key differences between the three parts?

A: The primary differences are housing material (LCP vs. PA66), contact tail length (0.102" to 0.150" range), color (black vs. green), and UL current rating (10A main part vs. 15A substitutes). All three parts share identical pitch, position count, orientation, insulation height, voltage rating, and flammability classification.

Q: Are there any compliance or regulatory differences?

A: All three parts are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Molex 0395350003 specifies ROHS3 compliance, indicating alignment with the most recent RoHS directive. TE Connectivity 796867-3 and Molex 0395350003 both carry REACH Affected status, which may be relevant for certain supply chain requirements.

Q: Does the longer contact tail length of the substitute parts affect compatibility?

A: Contact tail length differences (0.102" vs. 0.150" vs. 0.138") directly impact solder pad design and PCB layout. Longer tails may require deeper pad penetration or modified soldering profiles. PCB design verification is necessary before substitution to ensure adequate solder joint formation and mechanical support.

Q: Can I use the substitute parts if my application requires the specific housing material of the main part?

A: No. If the application specifies Liquid Crystal Polymer (LCP) housing for thermal, mechanical, or electrical reasons, the substitute parts with Polyamide (PA66) housing are not interchangeable. Both materials meet UL94 V-0 flammability requirements, but their thermal and mechanical properties differ.

Q: What inventory considerations should I account for?

A: Phoenix Contact 1955646 has 1096 pcs in stock. Molex 0395350003 has 4908 pcs available, and TE Connectivity 796867-3 has 2512 pcs available. Substitute parts offer significantly higher inventory levels, which may support extended production runs or mitigate supply constraints.
