Phoenix Contact 1936021 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1936021 is a 3-position terminal block header with male pins, shrouded on 4 sides, designed for vertical through-hole mounting with 0.200" (5.08mm) pitch spacing. This component is part of the COMBICON MSTBVA series and is actively manufactured. Terminal block headers are essential interconnection components in industrial control systems, power distribution panels, and modular electronic assemblies where reliable, field-serviceable connections are required. Equivalent parts may be necessary due to supply chain constraints, regional availability, or design standardization across manufacturing facilities.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1936021 and TE Connectivity 796636-3 are actively manufactured components with ROHS3 compliance and UL94 V-0 flammability certification, meeting current regulatory requirements for industrial terminal block applications.

The TE Connectivity 796636-3 provides a higher current rating (15A versus 12A), making it suitable for applications where the Phoenix Contact part is specified but higher current capacity is available. The housing material difference (Polyamide versus PBT) does not affect functional equivalence, as both materials meet the same flammability standard and are suitable for the specified voltage and current ratings.

Selection between these parts should be based on PCB layout constraints related to contact tail length (3.90mm versus 4.60mm), housing material compatibility with the application environment, and supply chain availability. Both parts maintain identical electrical performance at the specified 300V UL rating and support the same 5.08mm pitch interconnection standard.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796636-3 be used as a direct replacement for the Phoenix Contact 1936021?

A: Yes, the 796636-3 is functionally equivalent for applications requiring a 3-position, 5.08mm pitch, vertical through-hole terminal block header with male pins and 4-side shrouding. Both parts meet UL94 V-0 flammability requirements and ROHS3 compliance. Verify PCB layout compatibility due to the 0.04" (1.0mm) difference in contact tail length.

Q: What is the significance of the current rating difference between these parts?

A: The TE Connectivity 796636-3 is rated for 15A (UL), while the Phoenix Contact 1936021 is rated for 12A (UL). The higher rating on the 796636-3 indicates greater current-carrying capacity. For applications designed around the 12A specification, the 15A-rated part provides additional margin and is acceptable for use.

Q: Are there differences in housing material that affect performance?

A: The Phoenix Contact 1936021 uses PBT (Polybutylene Terephthalate), while the TE Connectivity 796636-3 uses PA66 (Polyamide, Nylon 6/6). Both materials are UL94 V-0 rated and suitable for the specified voltage and current ratings. Material selection may be relevant for specific environmental conditions or mechanical stress requirements in the application.

Q: How do the contact tail lengths affect PCB design?

A: The Phoenix Contact 1936021 has a contact tail length of 0.154" (3.90mm), while the TE Connectivity 796636-3 measures 0.138" (4.60mm). This 0.04" difference may impact PCB hole depth and solder joint formation. Verify that the PCB design accommodates the substitute part's tail length to ensure proper solder joint quality and mechanical stability.

Q: Are both parts suitable for the same voltage and current applications?

A: Both parts are rated for 300V (UL). The TE Connectivity 796636-3 exceeds the current requirement at 15A versus the Phoenix Contact 1936021 at 12A. Both parts are suitable for applications within the 12A/300V envelope and below.
