Phoenix Contact 1914946 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1914946 is an 11-position terminal block header with male pins, featuring a shrouded 4-side design and 0.197" (5.00mm) pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations.

The 1914946 operates at 12A (IEC) / 12A (UL) and 320V (IEC) / 300V (UL), with press-fit termination and green polybutylene terephthalate (PBT) housing. Equivalent alternatives must maintain compatibility across electrical ratings, mechanical dimensions, and mounting characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1914946 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Number of positions: 11
• Pitch: 0.197" (5.00mm)
• Header orientation: Vertical
• Type: Header with male pins, shrouded (4 side)
• Mounting type: Through hole
• Minimum current rating: 12A (IEC)
• Minimum voltage rating: 320V (IEC)
• Flammability rating: UL94 V-0

Allowable Variations:

• Termination style (press-fit vs. solder)
• Housing material (PBT, polyamide, or liquid crystal polymer)
• Housing color
• Contact tail length
• Contact mating finish
• Product status (active substitutes preferred for obsolete parts)

The identified substitute parts meet these criteria while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755590 (COMBICON MSTBVA Series)

The 1755590 is a direct functional equivalent with active product status. It maintains identical position count, pitch, orientation, and shrouded male pin configuration. Electrical ratings exceed the original specification (400V IEC vs. 320V IEC). The primary difference is solder termination versus press-fit, requiring PCB design accommodation. Housing material transitions from PBT to polyamide nylon, maintaining UL94 V-0 compliance. This substitute is suitable for applications where solder termination is acceptable and PCB layout permits the change.

Phoenix Contact 1837116 (COMBICON CCVA Series)

The 1837116 provides an alternative with enhanced electrical performance (16A UL rating vs. 12A UL). It maintains core mechanical compatibility with identical position count, pitch, and orientation. Solder termination applies. Housing material is liquid crystal polymer (LCP) with black color instead of green. Contact tail length is reduced to 0.079" (2.00mm) versus 0.154" (3.90mm), requiring PCB footprint verification. Operating temperature range is specified (-40°C to 100°C), providing environmental clarity absent in the original part. This substitute is suitable for applications requiring higher current capacity and where black housing and shorter contact tails are compatible with system design.

Both substitutes maintain the shrouded 4-side male pin header configuration and UL94 V-0 flammability rating. Selection depends on termination method compatibility, housing material requirements, and mechanical footprint constraints.

Frequently Asked Questions (FAQ)

Q: Can the 1755590 directly replace the 1914946 in existing designs?

A: Functional replacement is possible if the PCB design accommodates solder termination instead of press-fit. The 11-position, 5.00mm pitch, and vertical through-hole mounting are identical. Electrical ratings are equal or superior. Housing material change from PBT to polyamide nylon does not affect electrical performance or flammability compliance.

Q: What is the primary difference between the 1755590 and 1837116 substitutes?

A: The 1755590 maintains the original green housing and 0.154" contact tail length with polyamide nylon material. The 1837116 offers higher UL current rating (16A vs. 12A), black LCP housing, and shorter 0.079" contact tails. Both use solder termination. Selection depends on electrical requirements, housing color specification, and PCB footprint compatibility.

Q: Does the 1837116's shorter contact tail length affect compatibility?

A: Contact tail length affects PCB hole depth and component seating. The 1837116 contact tail of 0.079" (2.00mm) is shorter than the original 0.154" (3.90mm). PCB design must accommodate this difference. Verify hole depth and component clearance before substitution.

Q: Are both substitutes RoHS compliant?

A: The 1755590 is ROHS3 compliant with MSL 1 (Unlimited). The 1837116 does not specify RoHS status in provided data. Verify compliance requirements for your application before selection.

Q: What is the operating temperature range for these parts?

A: The original 1914946 does not specify operating temperature. The 1755590 does not specify operating temperature. The 1837116 specifies -40°C to 100°C. If operating temperature is a design constraint, the 1837116 provides explicit environmental specification.

Q: Can press-fit and solder termination be used interchangeably?

A: No. Press-fit termination requires specific PCB pad design and insertion force. Solder termination requires solder reflow or wave soldering. Both substitutes use solder termination, requiring PCB redesign if the original design used press-fit. Verify manufacturing process compatibility before substitution.
