Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1914071 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (IEC minimum 12A), voltage rating (IEC minimum 320V), and UL ratings must meet or exceed the original specification
• Physical Compatibility: 4-position configuration, 0.197" (5.00mm) pitch, vertical orientation, and through-hole mounting must be identical
• Mechanical Compatibility: Shrouded (4-side) design, male pin configuration, and contact tail length (0.154" / 3.90mm) must match
• Housing Material: Polybutylene Terephthalate (PBT) or equivalent material with UL94 V-0 flammability rating
• Contact Finish: Tin plating for corrosion resistance and solderability

The two substitute parts listed below meet these core substitution criteria while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776906 (COMBICON MSTBV Series)

Part 1776906 is the primary substitute for the obsolete 1914071. Both components share identical electrical ratings (12A IEC, 300V UL), physical dimensions (4-position, 5.00mm pitch, vertical through-hole), and mechanical configuration (shrouded male pins, 3.90mm contact tail length). The 1776906 offers improved product status (Active) and ROHS3 compliance. The primary difference is termination style: the 1776906 uses solder termination instead of press-fit. The IEC voltage rating is elevated to 400V, providing additional margin. This part is suitable for direct replacement in applications where solder termination is acceptable.

Phoenix Contact 1837381 (COMBICON CCV Series)

Part 1837381 serves as an alternative substitute with enhanced electrical performance. It maintains the 4-position, 5.00mm pitch vertical through-hole configuration with shrouded male pins. The UL current rating is increased to 16A (compared to 12A for the main part), and it features copper alloy contacts with specified operating temperature range (-40°C). The contact tail length is reduced to 2.00mm, and the housing material is Liquid Crystal Polymer (LCP) instead of PBT. This part is suitable for applications requiring higher current capacity or extended temperature range, provided the shorter contact tail length is mechanically compatible with the PCB design.

Both substitutes are Active products with current manufacturing support and improved compliance certifications, making them preferable to the obsolete 1914071 for new designs and ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can I use part 1776906 as a direct replacement for 1914071?

A: Part 1776906 is electrically and mechanically compatible with 1914071 for the specified 12A / 320V (IEC) application. The primary difference is termination method: 1776906 uses solder termination while 1914071 uses press-fit. If your PCB design accommodates solder termination, 1776906 is a suitable replacement. Both parts maintain identical pitch (5.00mm), position count (4), orientation (vertical), and contact tail length (3.90mm).

Q: What is the difference between the termination styles?

A: The 1914071 uses press-fit termination, where contacts are mechanically pressed into plated through-holes. The 1776906 uses solder termination, where contacts are soldered to PCB pads. Solder termination provides stronger mechanical and electrical connections for high-vibration or high-current applications. Press-fit termination allows for component rework without solder reflow.

Q: Can I use part 1837381 instead of 1914071?

A: Part 1837381 is electrically compatible (12A IEC, 300V UL) and mechanically similar, but has a shorter contact tail length (2.00mm versus 3.90mm). This difference may affect PCB pad design and board layout. Verify that your PCB design accommodates the reduced tail length before substitution. The 1837381 offers higher UL current rating (16A) and extended operating temperature (-40°C), making it suitable for demanding applications.

Q: Are all three parts RoHS compliant?

A: Yes. The 1914071 is RoHS Compliant. Both substitutes (1776906 and 1837381) are ROHS3 Compliant, representing the current RoHS standard. All three parts are suitable for RoHS-regulated applications.

Q: What is the voltage difference between 1914071 and 1776906?

A: The 1914071 is rated for 320V (IEC). The 1776906 is rated for 400V (IEC). Both are rated for 300V (UL). The higher IEC voltage rating on 1776906 provides additional safety margin in high-voltage applications but does not affect compatibility for the 320V (IEC) specification of the original part.

Q: Which substitute should I choose for a new design?

A: For standard 12A / 320V applications with solder-compatible PCB design, use 1776906 (COMBICON MSTBV). For applications requiring higher current capacity (16A UL), extended temperature range (-40°C), or copper alloy contacts, use 1837381 (COMBICON CCV), provided the 2.00mm contact tail length is compatible with your PCB design.
