Phoenix Contact 1915039 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915039 is a 19-position terminal block header with male pins, shrouded on four sides, designed for 0.197" (5.00mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary 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 of the Phoenix Contact 1915039 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Number of positions: 19
• Pitch: 0.197" (5.00mm)
• Header orientation: Vertical
• Connector type: Header with male pins, shrouded (4 side)
• Mounting method: Through hole
• Minimum current rating: 12A (IEC)
• Minimum voltage rating: 320V (IEC)
• Flammability rating: UL94 V-0

The two substitute parts listed—Phoenix Contact 1755671 and 1837190—meet these core electrical and mechanical requirements. Both maintain the 19-position configuration, 5.00mm pitch, vertical orientation, and through-hole mounting. Both achieve UL94 V-0 flammability compliance and support the required current and voltage specifications under their respective standards.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products from Phoenix Contact, providing continuity for the obsolete 1915039 model. Selection between them depends on specific application requirements:

Phoenix Contact 1755671 maintains the closest mechanical compatibility with the original part, featuring identical contact tail length (0.154" / 3.90mm) and green color. It supports 400V IEC rating, exceeding the original 320V specification. The solder termination style differs from the original press-fit design but is standard for this product category. RoHS3 compliance and MSL 1 rating provide modern supply chain compatibility.

Phoenix Contact 1837190 offers enhanced current capacity under UL standards (16A versus 12A) and extended operating temperature range (-40°C to 100°C). The shorter contact tail length (0.079" / 2.00mm) and black housing color represent design variations. Liquid Crystal Polymer housing provides superior thermal and chemical resistance compared to the original PBT material. This part is suitable for applications requiring higher thermal performance or extended temperature operation.

Both parts maintain the critical 19-position, 5.00mm pitch, vertical through-hole configuration and UL94 V-0 flammability compliance required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1755671 directly replace the 1915039 in existing designs?

A: Yes. The 1755671 maintains electrical equivalence (12A / 320V IEC minimum), identical mechanical pitch and position count, and matching through-hole mounting. The termination style change from press-fit to solder requires PCB design verification but does not affect electrical performance.

Q: What is the primary difference between the two substitute parts?

A: The 1755671 prioritizes mechanical compatibility with the original part (identical contact tail length and green color). The 1837190 offers enhanced specifications: higher UL current rating (16A), extended operating temperature range, and superior housing material (LCP). Contact tail length differs (2.00mm versus 3.90mm), requiring PCB layout verification.

Q: Are both substitute parts suitable for high-temperature applications?

A: The 1837190 specifies operating temperature range of -40°C to 100°C. The 1915039 and 1755671 do not provide operating temperature specifications in the available data. For applications requiring defined temperature performance, the 1837190 is the specified choice.

Q: Does the change from press-fit to solder termination affect compatibility?

A: Termination style affects assembly method and PCB design. Press-fit (original) and solder (substitutes) are mechanically and electrically distinct connection methods. PCB footprint and assembly process must be verified before implementation.

Q: Are the substitute parts RoHS compliant?

A: The 1755671 is RoHS3 compliant. The 1837190 does not specify RoHS status in the provided data. Regulatory compliance verification is required for applications with RoHS requirements.

Q: What is the significance of the different housing materials?

A: The 1915039 uses Polybutylene Terephthalate (PBT), the 1755671 uses Polyamide (PA/Nylon), and the 1837190 uses Liquid Crystal Polymer (LCP). Material selection affects thermal stability, chemical resistance, and mechanical properties. LCP (1837190) provides superior performance in demanding thermal or chemical environments.
