Phoenix Contact 1915042 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915042 is a 20-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 1915042 operates at 12A (IEC) / 12A (UL) and 320V (IEC) / 300V (UL), with press-fit termination and green polybutylene terephthalate (PBT) housing. RoHS compliance and UL94 V-0 flammability rating are standard specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915042 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must maintain 20 positions at 0.197" (5.00mm) pitch
• Header Type & Orientation: Male pins, shrouded (4 side), vertical through-hole configuration
• Electrical Ratings: Minimum 12A current and 300V voltage (UL) / 320V voltage (IEC)
• Mounting Interface: Through-hole PCB mounting compatibility
• Flammability & Compliance: UL94 V-0 rating and RoHS compliance required

The identified substitute parts (1755684 and 1837200) meet these core functional requirements while differing in termination style, housing material, and product status. Both substitutes are active products with current availability, addressing the obsolescence of the original 1915042.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755684 is suitable for applications requiring solder termination with enhanced voltage capability (400V IEC). This part maintains identical pitch, position count, and insulation height as the 1915042, with ROHS3 compliance confirming current manufacturing standards. The polyamide housing provides alternative material properties while maintaining UL94 V-0 flammability rating.

Phoenix Contact 1837200 offers the highest current rating (16A UL) and defined operating temperature range (-40°C ~ 100°C), making it appropriate for temperature-sensitive applications. The liquid crystal polymer housing and shorter contact tail length (0.079" vs. 0.154") represent material and dimensional differences requiring PCB layout verification. This part is recommended for new designs where thermal performance and extended current capacity are required.

Both substitutes are active products with documented availability, eliminating supply chain risk associated with the obsolete 1915042.

Frequently Asked Questions (FAQ)

Q: Can the 1915042 be directly replaced with 1755684 or 1837200 without PCB modification?

A: Direct replacement depends on termination compatibility. The 1915042 uses press-fit termination, while both substitutes use solder termination. PCB pad design and hole sizing must accommodate solder termination. The 1837200 has a shorter contact tail length (0.079" vs. 0.154"), which may require PCB layout adjustment.

Q: What are the electrical differences between the substitute parts?

A: The 1755684 provides 400V IEC rating compared to 320V for both the 1915042 and 1837200. The 1837200 offers 16A UL current rating versus 12A for the other parts. Both maintain 300V UL and 12A IEC ratings compatible with the original specification.

Q: Are there material compatibility considerations?

A: The 1915042 uses polybutylene terephthalate (PBT) housing. The 1755684 substitutes polyamide (PA/Nylon), while the 1837200 uses liquid crystal polymer (LCP). All three maintain UL94 V-0 flammability rating. Material selection should be verified against application environmental exposure and chemical compatibility requirements.

Q: Which substitute is recommended for new designs?

A: The 1837200 is recommended for new designs due to active product status, defined operating temperature range (-40°C ~ 100°C), and higher current capacity (16A UL). The 1755684 is suitable for direct functional replacement where solder termination is acceptable and enhanced voltage rating (400V IEC) is beneficial.

Q: What is the impact of color difference (green vs. black)?

A: The 1915042 and 1755684 are green; the 1837200 is black. Color difference is cosmetic and does not affect electrical or mechanical function. Selection should be based on application requirements and visual identification needs.
