Phoenix Contact 1915783 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915783 is a 23-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 equivalent substitute parts 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 eligibility for the Phoenix Contact 1915783 terminal block is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 23
• Pitch: 0.197" (5.00mm)
• Header orientation: Vertical
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Material flammability rating: UL94 V-0
• Insulation height: 0.472" (12.00mm)

Allowable Variations:

• Termination style: Press-fit or solder acceptable
• Housing material: PBT, Polyamide (PA/Nylon), or Liquid Crystal Polymer (LCP)
• Current rating: Equal to or greater than 12A
• Voltage rating: Equal to or greater than 320V (IEC) or 300V (UL)
• Contact tail length: Variations permitted based on application requirements
• Product status: Active preferred for new designs; obsolete acceptable for legacy system replacement

The two substitute parts listed below meet these criteria and are confirmed compatible with the original 1915783 specification.

Parameter Comparison

Engineering Selection Recommendations

1755710 Substitute Selection: The Phoenix Contact 1755710 is an active product with identical positional, pitch, and dimensional specifications to the 1915783. It features solder termination instead of press-fit, requiring PCB design modification. The housing material differs (Polyamide/Nylon versus PBT), and the IEC voltage rating is elevated to 400V, providing additional margin. This part is RoHS compliant and suitable for new designs requiring solder-based assembly.

1837239 Substitute Selection: The Phoenix Contact 1837239 is an active product meeting all critical dimensional and electrical parameters. It features solder termination, Liquid Crystal Polymer (LCP) housing material, and an elevated UL current rating of 16A. The contact tail length is reduced to 0.079" (2.00mm), requiring verification of PCB pad layout compatibility. This part includes specified operating temperature range (-40°C ~ 100°C) and is suitable for applications requiring enhanced thermal performance or higher current capacity.

Selection Criteria:

• For press-fit termination requirement: Original 1915783 only (obsolete status requires inventory assessment)
• For solder termination with standard thermal range: 1755710 recommended
• For solder termination with extended thermal range and higher current: 1837239 recommended

Frequently Asked Questions (FAQ)

Q: Can the 1755710 directly replace the 1915783 in existing PCB designs? A: No. The 1755710 uses solder termination while the 1915783 uses press-fit termination. PCB pad design and assembly process must be modified accordingly.

Q: What is the impact of the different housing materials (PBT, Polyamide, LCP)? A: Housing material affects thermal stability, chemical resistance, and mechanical properties. All three materials meet UL94 V-0 flammability requirements. LCP (1837239) provides superior thermal performance; Polyamide (1755710) offers cost efficiency; PBT (1915783) provides balanced performance.

Q: Is the reduced contact tail length of the 1837239 (0.079" vs 0.154") a compatibility issue? A: Contact tail length affects PCB pad depth and solder joint formation. Verify PCB design specifications before selecting the 1837239. Shorter tail length may require pad geometry adjustment.

Q: Are the substitute parts RoHS compliant? A: The 1755710 is confirmed RoHS compliant. The 1837239 RoHS status is not specified in the provided data. Verify compliance requirements with your procurement specifications.

Q: Can I use the 1837239 in applications requiring the original operating temperature specification? A: The 1915783 operating temperature is not specified. The 1837239 specifies -40°C ~ 100°C operation. If your application requires this temperature range, the 1837239 is suitable. If your application requires different temperature limits, verify compatibility independently.

Q: What is the significance of the voltage rating difference between 1755710 (400V IEC) and the original (320V IEC)? A: The 1755710 provides 25% higher voltage margin under IEC conditions, offering additional safety headroom. This does not affect compatibility; it represents an improvement in electrical performance.
