Phoenix Contact 1914975 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1914975 is a 14-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.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1914975 is determined by the following critical parameters:

Position Count & Pitch: All substitute parts must maintain 14 positions at 0.197" (5.00mm) pitch to ensure PCB footprint compatibility
Header Type & Orientation: Vertical orientation with male pins and four-side shrouding is required for mechanical fit
Electrical Ratings: Minimum current rating of 12A (IEC) and voltage rating of 320V (IEC) must be maintained
Mounting Type: Through-hole mounting is mandatory for PCB assembly compatibility
Flammability Rating: UL94 V-0 compliance is required for safety-critical applications

The two identified substitute parts (1755626 and 1837145) meet these core substitution criteria while differing in termination style, housing material, and color specification.

Engineering Selection Recommendations

Phoenix Contact 1755626 is an active-status substitute offering improved voltage rating (400V IEC vs. 320V IEC) and current ROHS3 compliance. The primary design consideration is termination style: this part uses solder termination rather than press-fit, requiring PCB assembly process modification. Housing material differs (polyamide/nylon vs. PBT), and color remains green for visual consistency with the original design.

Phoenix Contact 1837145 is an active-status substitute with enhanced current rating (16A UL vs. 12A UL) and extended operating temperature range (-40°C to 100°C). This part uses solder termination and liquid crystal polymer (LCP) housing material. The contact tail length is shorter (0.079" vs. 0.154"), which may affect PCB layout compatibility. Housing color is black rather than green.

Both substitutes maintain the critical electrical and mechanical parameters required for 14-position, 5.00mm pitch vertical through-hole terminal block header applications. Selection between them depends on termination process capability, housing material compatibility, and color specification requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1755626 be used as a direct replacement for 1914975?

A: Substitution is mechanically and electrically feasible. The primary difference is termination style: 1755626 requires solder attachment instead of press-fit. PCB assembly processes must accommodate this change. Electrical ratings are equivalent or superior (400V IEC vs. 320V IEC).

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

A: The main part uses polybutylene terephthalate (PBT), while 1755626 uses polyamide (PA/nylon) and 1837145 uses liquid crystal polymer (LCP). All three materials meet UL94 V-0 flammability requirements. Material selection affects thermal performance and chemical resistance; verify compatibility with the operating environment.

Q: Does the shorter contact tail length of 1837145 affect compatibility?

A: Contact tail length (0.079" vs. 0.154") directly impacts PCB hole depth and solder joint formation. Shorter tails may require PCB design modification. Verify PCB layout specifications before selecting this substitute.

Q: Are there packaging differences between these parts?

A: The main part 1914975 has unspecified packaging, while both substitutes are supplied in bulk packaging. Confirm packaging requirements for procurement and inventory management.

Q: Which substitute offers the best compliance for new designs?

A: Both 1755626 and 1837145 are active-status products. 1755626 carries ROHS3 compliance certification. 1837145 provides extended operating temperature range (-40°C to 100°C). Selection depends on specific compliance and environmental requirements for the target application.
