Phoenix Contact 1900170 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1900170 is a 12-position terminal block header with male pins, shrouded on four sides, featuring 0.197" (5.00mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Terminal block headers of this configuration serve as connection interfaces in industrial control systems, power distribution modules, and signal routing applications where reliable electrical contact and mechanical stability are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1900170 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed IEC and UL specifications (12A/400V IEC minimum; 15A/300V UL minimum)
• Mechanical Compatibility: 12 positions, 0.197" (5.00mm) pitch, 90° right-angle orientation, through-hole mounting, and four-side shrouding
• Interface Type: Male pins with mating and mounting flange
• Material Standards: UL94 V-0 flammability rating and RoHS compliance

Two substitute parts meet these criteria:

1. Phoenix Contact 1776799 - Active status, solder termination variant within COMBICON MSTB series
2. Phoenix Contact 1836780 - Active status, solder termination variant within COMBICON CC series with enhanced current rating

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776799 is the primary substitute for the 1900170. Both components share identical electrical ratings (12A/400V IEC, 15A/300V UL), mechanical configuration, and housing material (PBT). The 1776799 maintains active product status and ROHS3 compliance. The primary difference is termination style: the 1900170 uses press-fit termination while the 1776799 uses solder termination. This substitution is suitable for applications where solder-based PCB assembly is the standard manufacturing process.

Phoenix Contact 1836780 is a secondary substitute with enhanced current capacity (16A UL rating versus 15A). The 1836780 operates at reduced IEC voltage (320V versus 400V) and features a shorter contact tail length (0.079" versus 0.165"), which may affect PCB layout compatibility. The housing material differs (LCP versus PBT), and the component uses solder termination. This substitution is appropriate for applications requiring higher current capacity and where the reduced voltage rating and modified mechanical dimensions are acceptable.

Both substitutes are active products with current manufacturing support, addressing the obsolescence status of the 1900170.

Frequently Asked Questions (FAQ)

Q: Can the 1776799 directly replace the 1900170 in existing designs?

A: Mechanical and electrical compatibility is confirmed for the same 12-position, 5.00mm pitch, 90° right-angle configuration. The primary consideration is termination method: the 1900170 uses press-fit termination for direct PCB insertion, while the 1776799 requires solder attachment. PCB design modifications may be necessary to accommodate solder pad patterns.

Q: What is the significance of the contact tail length difference between these parts?

A: Contact tail length determines insertion depth into the PCB. The 1900170 has a 0.165" (4.19mm) tail, the 1776799 has 0.138" (4.60mm), and the 1836780 has 0.079" (2.00mm). Shorter tail lengths require corresponding PCB via depth adjustments. Verify PCB stackup compatibility before substitution.

Q: Are there voltage rating differences that affect circuit design?

A: The 1900170 and 1776799 both support 400V IEC rating. The 1836780 is rated at 320V IEC. For applications operating above 320V, the 1836780 is not suitable. The UL voltage rating (300V) is identical across all three parts.

Q: Does housing material affect electrical performance?

A: The 1900170 and 1776799 use PBT (Polybutylene Terephthalate), while the 1836780 uses LCP (Liquid Crystal Polymer). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and higher temperature capability, but both materials are suitable for standard industrial applications within the specified operating ranges.

Q: What is the impact of RoHS compliance differences?

A: The 1900170 is RoHS Compliant, and the 1776799 is ROHS3 Compliant. ROHS3 represents the current regulatory standard. Both parts are lead-free and suitable for modern manufacturing environments. The 1836780 RoHS status is not specified in available documentation.

Q: Can the 1836780 be used in applications requiring 400V operation?

A: No. The 1836780 is rated at 320V IEC maximum. Applications requiring 400V operation must use the 1900170 or 1776799.
