Phoenix Contact 1899951 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899951 is a 13-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 equivalent and substitute parts essential for ongoing system maintenance and new design implementations.

The primary function of this terminal block header is to provide a standardized connection interface for 13 discrete signal or power lines in industrial control and automation applications. Substitution becomes necessary when the original part reaches end-of-life status or when design requirements favor active production alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899951 is determined by strict alignment with the following critical parameters:

Core Compatibility Parameters:

• Number of positions: 13
• Pitch: 0.197" (5.00mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Electrical ratings: Current (IEC) 12A minimum, Voltage (IEC) 400V minimum
• Material flammability: UL94 V-0
• RoHS compliance: Required

Allowable Variations:

• Termination style: Press-Fit or Solder acceptable
• Housing material: PBT, Polyamide (PA/Nylon), or Liquid Crystal Polymer (LCP)
• Contact tail length: Variation permitted within mechanical envelope constraints
• Product status: Active or Obsolete
• Color: Green or Black

The two identified substitute parts (1757572 and 1836450) maintain all core compatibility parameters while differing in termination methodology, housing material composition, and contact tail geometry.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1757572 (COMBICON MSTBA Series)

Part 1757572 is an active production alternative with identical electrical specifications to the main part. The primary distinction is termination methodology: solder termination replaces press-fit termination. Housing material transitions from PBT to Polyamide (PA/Nylon), maintaining UL94 V-0 flammability compliance. Contact tail length is reduced from 0.165" to 0.138", which may require PCB layout adjustment. This substitute is suitable for applications where solder termination is preferred and PCB design accommodates the shorter tail geometry.

Phoenix Contact 1836450 (COMBICON CCA Series)

Part 1836450 is an active production alternative with enhanced electrical performance. UL current rating increases to 16A, and IEC voltage rating is 320V (compared to 400V on the main part). Housing material is Liquid Crystal Polymer (LCP) with specified operating temperature range of -40°C to 100°C. Contact tail length is significantly reduced to 0.079", requiring substantial PCB layout modification. This substitute is suitable for applications with lower voltage requirements and where compact PCB footprint is advantageous.

Both substitutes maintain the 13-position, 5.00mm pitch, 90° right-angle configuration and through-hole mounting type. Selection between substitutes depends on termination preference, PCB layout constraints, and specific electrical requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1757572 directly replace 1899951 in existing designs?

A: Electrical compatibility is confirmed. The primary consideration is termination methodology: 1757572 uses solder termination versus press-fit on the original part. PCB design must accommodate the reduced contact tail length of 0.138" (versus 0.165" on 1899951). Housing material change from PBT to Polyamide does not affect electrical performance or flammability rating.

Q: What are the mechanical differences between the three parts?

A: Contact tail length varies: 1899951 measures 0.165" (4.19mm), 1757572 measures 0.138" (4.60mm), and 1836450 measures 0.079" (2.00mm). Insulation height remains consistent at approximately 0.339". These differences affect PCB hole depth and component placement. Housing material also differs: PBT (1899951), Polyamide (1757572), and Liquid Crystal Polymer (1836450).

Q: Are all three parts RoHS compliant?

A: Yes. All three parts—1899951, 1757572, and 1836450—carry RoHS Compliant status and UL94 V-0 flammability rating, meeting environmental and safety standards for industrial applications.

Q: What is the voltage difference between 1899951 and 1836450?

A: The IEC voltage rating differs: 1899951 is rated 400V, while 1836450 is rated 320V. Both maintain 300V UL rating. Applications requiring 400V IEC compliance must use 1899951 or 1757572. Applications operating at 320V or below may use 1836450.

Q: Which substitute offers the best compatibility for direct PCB replacement?

A: Phoenix Contact 1757572 offers the closest mechanical compatibility, with identical insulation height and minimal contact tail length reduction (0.027" difference). This minimizes PCB redesign requirements while providing active production status and identical electrical specifications.

Q: What is the inventory status of these parts?

A: 1899951 (obsolete) has 983 units in stock. 1757572 (active) has 1052 units available. 1836450 (active) has 775 units available. Active production alternatives ensure long-term supply continuity.
