Phoenix Contact 1915178 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915178 is a 13-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 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 a press-fit termination style and green polybutylene terephthalate (PBT) housing rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915178 is determined by strict alignment with the following core parameters:

• Position Count & Pitch: All substitute parts must maintain 13 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with existing mating connectors and PCB layouts.
• Header Type & Orientation: Substitutes must be male pin headers with four-side shrouding in vertical orientation to maintain form factor and mounting compatibility.
• Mounting Technology: Through-hole mounting is required; substitutes may employ either press-fit or solder termination styles, as both are compatible with through-hole PCB applications.
• Electrical Ratings: Substitute parts must meet or exceed the IEC and UL voltage and current specifications (minimum 320V IEC / 300V UL and 12A).
• Housing Material & Flammability: UL94 V-0 rated materials are required to maintain flame retardancy compliance.
• Mechanical Dimensions: Contact tail length and insulation height must be compatible with existing PCB hole patterns and clearance requirements.

Two substitute parts meet these criteria: Phoenix Contact 1776993 (COMBICON MSTBV series, solder termination, active status) and Phoenix Contact 1837475 (COMBICON CCV series, solder termination, active status, black color variant).

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776993 is the primary substitute for the 1915178. This part maintains identical mechanical dimensions (0.154" contact tail length, 0.472" insulation height), operates at higher IEC voltage (400V vs. 320V), and carries active product status. The transition from press-fit to solder termination requires PCB design verification to confirm solder pad compatibility. RoHS compliance and MSL 1 rating provide enhanced supply chain reliability.

Phoenix Contact 1837475 serves as an alternative substitute with the following considerations: UL current rating is elevated to 16A, exceeding the original 12A specification. Contact tail length is reduced to 0.079" (2.00mm), requiring verification against existing PCB hole patterns and clearance margins. Housing material differs (LCP vs. PBT), and color is black rather than green. Operating temperature range (-40°C to 100°C) is explicitly specified. This part is suitable only when PCB layout accommodates the shorter contact tail and when color differentiation is acceptable.

Both substitutes maintain the required 13-position, 5.00mm pitch configuration, four-side shrouding, vertical orientation, and UL94 V-0 flammability rating. Selection between 1776993 and 1837475 depends on PCB design constraints, particularly contact tail length compatibility and color requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1915178 be directly replaced with the 1776993 or 1837475 without PCB modification?

A: Direct replacement depends on termination method compatibility. The 1915178 uses press-fit termination; both substitutes employ solder termination. PCB hole sizing and pad design must be verified to accommodate solder termination. Contact tail length must also be confirmed: 1776993 matches the original 0.154" (3.90mm), while 1837475 is shorter at 0.079" (2.00mm).

Q: What is the primary difference between the 1776993 and 1837475 substitutes?

A: The 1776993 maintains identical mechanical dimensions and green color to the original 1915178, with higher IEC voltage rating (400V). The 1837475 features a shorter contact tail (0.079" vs. 0.154"), black housing color, higher UL current rating (16A vs. 12A), and LCP housing material instead of PBT. The 1837475 also specifies operating temperature range (-40°C to 100°C).

Q: Are both substitutes electrically compatible with the original 1915178 application?

A: Both substitutes meet or exceed the electrical specifications of the 1915178. The 1776993 provides 400V IEC (vs. 320V original) and maintains 12A current rating. The 1837475 maintains 320V IEC and increases UL current to 16A. Both maintain 300V UL and 12A UL minimum ratings. Electrical compatibility is confirmed for applications within the original 320V / 12A envelope.

Q: Does the color difference between substitutes affect functionality?

A: Color is a visual identifier only and does not affect electrical or mechanical function. The 1915178 and 1776993 are green; the 1837475 is black. Color selection may be driven by system documentation, wiring standards, or visual identification requirements in the application.

Q: What is the impact of housing material differences (PBT vs. LCP)?

A: Both PBT (1915178, 1776993) and LCP (1837475) are UL94 V-0 rated and provide equivalent flame retardancy. LCP offers enhanced dimensional stability and higher temperature capability. Both materials are suitable for through-hole terminal block applications. Material selection should be based on operating environment and thermal requirements.

Q: Why is the 1915178 obsolete, and what does this mean for long-term availability?

A: Obsolete status indicates the 1915178 is no longer manufactured by Phoenix Contact. Both substitute parts carry active status, ensuring continued availability and supply chain support. Migration to either 1776993 or 1837475 is recommended for new designs and ongoing production requirements.
