Phoenix Contact 1914865 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1914865 is a 3-position terminal block header with male pins, shrouded on 4 sides, featuring 0.197" (5.00mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of suitable 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 UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1914865 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must maintain 3 positions at 0.197" (5.00mm) pitch
• Header Type & Orientation: Vertical orientation with male pins and 4-side shrouding required
• Mounting Configuration: Through-hole mounting with matching contact tail length (0.154" / 3.90mm) and insulation height (0.472" / 12.00mm)
• Electrical Ratings: Minimum 12A current capacity and 300V voltage rating (UL standard)
• Compliance: RoHS compliance and UL94 V-0 flammability rating

The two identified substitute parts meet these core substitution criteria while differing in termination style (solder vs. press-fit), housing material composition, and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755529 is the primary substitute for applications requiring direct functional equivalence. This part maintains identical electrical ratings (12A IEC, 300V UL), pitch, position count, and physical dimensions. The transition from press-fit to solder termination requires PCB design modification but provides active product status with ROHS3 compliance. Housing material changes from PBT to polyamide (PA/nylon), which maintains UL94 V-0 flammability rating.

Phoenix Contact 1837035 serves as an alternative substitute with enhanced current capacity (16A UL) and operates at -40°C minimum temperature. This part features liquid crystal polymer (LCP) housing material and maintains the 3-position, 5.00mm pitch configuration. The contact tail length is reduced to 0.079" (2.00mm), requiring PCB footprint adjustment. Solder termination applies to this variant as well. Material flammability rating is not specified for this part.

Both substitutes are active products with current manufacturing support, addressing the obsolescence status of the original 1914865 component.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1755529 be used as a direct replacement for 1914865?

A: Functional compatibility is established through matching position count (3), pitch (5.00mm), header type (male pins, 4-side shrouded), mounting type (through-hole), and electrical ratings (12A IEC, 300V UL). The primary difference is termination style: 1755529 uses solder termination versus press-fit on the original. PCB design modification is required to accommodate solder pads instead of press-fit holes.

Q: What are the key differences between 1755529 and 1837035?

A: Both are solder-terminated alternatives, but 1837035 provides higher UL current rating (16A vs. 12A), operates at -40°C minimum temperature, and uses LCP housing material. The contact tail length differs: 1837035 measures 0.079" (2.00mm) versus 0.154" (3.90mm) on 1755529. This tail length difference requires PCB footprint adjustment for 1837035.

Q: Are both substitute parts RoHS compliant?

A: Yes. Phoenix Contact 1755529 carries ROHS3 compliance, and 1837035 is RoHS compliant. Both meet current regulatory requirements for electronic component manufacturing.

Q: Does housing material affect electrical performance?

A: Housing material composition does not alter the electrical ratings (current and voltage capacity). Material selection impacts thermal properties, mechanical durability, and flammability characteristics. The 1914865 uses PBT (UL94 V-0), 1755529 uses polyamide/nylon (UL94 V-0), and 1837035 uses LCP. All maintain equivalent electrical performance within specified ratings.

Q: What is the impact of changing from press-fit to solder termination?

A: Press-fit termination (1914865) requires precision-drilled holes with specific tolerances for mechanical insertion. Solder termination (1755529, 1837035) requires solder pads on the PCB and reflow soldering during assembly. This represents a manufacturing process change but does not affect electrical or mechanical performance once properly assembled.

Q: Can 1837035 be used in applications requiring -40°C operation?

A: Yes. Phoenix Contact 1837035 specifies -40°C minimum operating temperature, whereas the original 1914865 does not specify a minimum temperature rating. If low-temperature operation is required, 1837035 is the appropriate selection among the available substitutes.
