Phoenix Contact 1914933 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1914933 is a 10-position terminal block header with male pins, shrouded on four sides, featuring 0.197" (5.00mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 12A (IEC) / 12A (UL) and 320V (IEC) / 300V (UL), with press-fit termination and green polybutylene terephthalate (PBT) housing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1914933 is determined by the following critical parameters: 10-position configuration, 0.197" (5.00mm) pitch, vertical through-hole orientation, male pin header with 4-side shrouding, and electrical ratings of 12A (IEC) / 12A (UL) and 320V (IEC) / 300V (UL).

Two substitute parts meet these core functional requirements:

Phoenix Contact 1755503 maintains identical position count, pitch, orientation, and shrouding. Electrical ratings are equivalent or superior (12A IEC, 400V IEC, 12A UL, 300V UL). The primary difference is termination style (solder versus press-fit) and housing material (polyamide/nylon versus PBT). This part is active and in production.

Phoenix Contact 1837103 maintains identical position count, pitch, orientation, and shrouding. Electrical ratings meet or exceed requirements (12A IEC, 320V IEC, 16A UL, 300V UL). Differences include termination style (solder versus press-fit), housing material (liquid crystal polymer versus PBT), color (black versus green), contact tail length (0.079" versus 0.154"), and specified operating temperature range (-40°C to 100°C). This part is active and in production.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755503 is recommended as the primary substitute for applications where termination method flexibility is acceptable. This part maintains active production status, ensuring long-term availability and supply chain stability. The solder termination style requires PCB design modification from the original press-fit configuration. Electrical performance exceeds the original specification with 400V IEC rating. RoHS3 compliance provides enhanced environmental regulatory alignment compared to the obsolete original part.

Phoenix Contact 1837103 is recommended for applications requiring enhanced electrical performance or where operating temperature specification is critical. The 16A UL rating provides additional current capacity. Active production status ensures availability. The shorter contact tail length (0.079" versus 0.154") requires PCB footprint verification before implementation. Black housing color differs from the original green, which may impact visual identification in legacy systems. Solder termination requires PCB design modification.

Both substitute parts maintain the critical functional parameters: 10-position configuration, 5.00mm pitch, vertical through-hole mounting, and 4-side shrouding. Selection between substitutes depends on termination method compatibility with existing PCB designs and specific electrical or environmental requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1755503 be used as a direct replacement for 1914933?

A: Functional compatibility is confirmed for position count, pitch, orientation, and electrical ratings. The primary consideration is termination method: 1755503 uses solder termination while 1914933 uses press-fit. PCB design modification is required to accommodate the different termination style.

Q: What is the key difference between 1755503 and 1837103?

A: Both are solder-terminated substitutes with identical position and pitch specifications. Key differences include housing material (polyamide/nylon versus liquid crystal polymer), contact tail length (0.154" versus 0.079"), color (green versus black), and UL current rating (12A versus 16A). Contact tail length difference requires PCB footprint verification.

Q: Why is the original 1914933 obsolete?

A: Product status is provided as obsolete in the manufacturer specification. Both identified substitutes are active production parts, ensuring continued availability for system maintenance and new designs.

Q: Are all three parts RoHS compliant?

A: Yes. The original 1914933 is RoHS Compliant. Substitute 1755503 is ROHS3 Compliant. Substitute 1837103 is RoHS Compliant. All meet environmental regulatory requirements.

Q: What is the impact of different housing materials on performance?

A: Housing materials differ (PBT, polyamide/nylon, and liquid crystal polymer) but all maintain UL94 V-0 flammability rating. Material selection affects mechanical properties and environmental resistance. Specific application requirements determine material suitability.

Q: Can 1837103 be used in applications requiring the original green color?

A: 1837103 is supplied in black housing. Color difference may impact visual identification in systems where color coding is used for circuit identification or maintenance procedures. Functional performance is not affected by color difference.

Q: What PCB modifications are required when switching from press-fit to solder termination?

A: Press-fit termination (1914933) uses through-hole pads designed for mechanical insertion. Solder termination (1755503, 1837103) requires standard through-hole solder pads. PCB layout and pad design must be verified for compatibility with the selected termination method.
