Phoenix Contact 1915835 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915835 is a 20-position terminal block header with male pins, featuring a shrouded 4-side design and 0.197" (5.00mm) pitch for 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 1915835 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must maintain 20 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with existing mating connectors and PCB layouts.
• Header Type & Orientation: Vertical through-hole male pin headers with shrouded design are required to match the original mounting configuration.
• Electrical Ratings: Substitute parts must meet or exceed the IEC and UL current and voltage specifications (12A / 320V IEC minimum; 12A / 300V UL minimum).
• Flammability & Material Compliance: UL94 V-0 rating is mandatory for safety-critical applications.
• Termination Compatibility: While the original part uses press-fit termination, solder termination substitutes are acceptable provided all other parameters align, as termination method does not affect mating interface compatibility.

Two active substitute parts meet these criteria: Phoenix Contact 1777060 and Phoenix Contact 1837543.

Parameter Comparison

Engineering Selection Recommendations

Both Phoenix Contact 1777060 and 1837543 are active product alternatives to the obsolete 1915835, meeting all critical substitution parameters for position count, pitch, header type, orientation, and electrical ratings.

Phoenix Contact 1777060 maintains identical mechanical dimensions (contact tail length 0.154", insulation height 0.472") and housing material (PBT) to the original part. It provides equivalent electrical performance with 12A / 400V (IEC) and 12A / 300V (UL) ratings. The primary difference is termination method (solder vs. press-fit). This part is RoHS compliant and represents the closest functional equivalent.

Phoenix Contact 1837543 offers enhanced electrical performance with 16A (UL) current rating and extended operating temperature range (-40°C to 100°C). It uses Liquid Crystal Polymer (LCP) housing material and features a shorter contact tail length (0.079" vs. 0.154"), which may require PCB layout verification. The black color differs from the original green. This part is suitable for applications requiring higher current capacity or wider temperature operation.

Selection between these substitutes depends on termination method compatibility with existing assembly processes and mechanical fit requirements within the application.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1777060 be used as a direct replacement for 1915835?

A: Yes, for applications where solder termination is compatible with assembly processes. The 1777060 maintains identical mechanical dimensions, pitch, position count, and housing material. Electrical ratings meet or exceed the original specification.

Q: What is the primary difference between 1777060 and 1837543?

A: The 1777060 uses PBT housing material with a longer contact tail (0.154"), while the 1837543 uses LCP housing with a shorter contact tail (0.079"). The 1837543 provides higher UL current rating (16A vs. 12A) and wider operating temperature range (-40°C to 100°C). Housing material and contact tail length may affect PCB compatibility.

Q: Are both substitute parts RoHS compliant?

A: The 1777060 is explicitly RoHS compliant. RoHS status for the 1837543 is not specified in the provided data.

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

A: No. Termination method affects assembly process only, not the mating interface. Both press-fit and solder termination styles produce identical male pin headers that mate with the same connector receptacles.

Q: Can the 1837543 be used in applications with space constraints?

A: The 1837543 has a shorter contact tail length (0.079" vs. 0.154"), which reduces PCB penetration depth. Verify that the shorter tail length is compatible with your PCB thickness and back-side clearance requirements before substitution.

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

A: Color is a visual identifier only and does not affect electrical or mechanical function. Selection between green (1915835, 1777060) and black (1837543) depends on application documentation or assembly marking requirements.
