Phoenix Contact 1894969 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1894969 is a 14-position terminal block header with male pins, featuring a shrouded 4-side design and 2.50mm (0.098") 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 where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1894969 is determined by the following critical parameters:

Functional Equivalence Criteria:

• Number of positions: 14
• Configuration: 7 positions per level, 2 levels
• Header type: Male pins with 4-side shrouding
• Termination: Solder through-hole mounting
• Orientation: Vertical

Electrical Compatibility Criteria:

• Current rating (minimum): 4A IEC / 4A UL
• Voltage rating (minimum): 320V IEC / 125V UL
• Contact finish: Tin or equivalent conductive coating

Mechanical Compatibility Criteria:

• Pitch tolerance: 2.50mm nominal (0.098")
• Contact tail length: 4.60mm nominal
• Insulation height: 17.50mm nominal
• Housing material: Polyamide (PA), Nylon

The substitute part Phoenix Contact 1844921 shares the same functional configuration (14 positions, 7 per level, 2 levels) and mounting style (vertical through-hole, solder termination) but operates at a different pitch specification (2.54mm vs. 2.50mm). This pitch difference represents a mechanical incompatibility that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The Phoenix Contact 1894969 is classified as obsolete. The Phoenix Contact 1844921 is an active product, ensuring ongoing availability and manufacturing support for future procurement requirements.

Compliance and Certification: Both parts maintain RoHS compliance. The 1844921 carries ROHS3 Compliant status and REACH Unaffected designation, representing current regulatory alignment. The 1894969 meets RoHS Compliant requirements with UL94 V-0 flammability rating explicitly documented.

Electrical Rating Differences: The 1844921 provides higher current capacity (6A vs. 4A) under both IEC and UL standards. Voltage ratings differ: the 1894969 supports 320V IEC and 125V UL, while the 1844921 supports 160V IEC and 150V UL. Application voltage requirements must be evaluated against these specifications.

Mechanical Incompatibility: The pitch difference (2.50mm vs. 2.54mm) represents a 0.04mm variance. This difference affects PCB footprint design and mating connector compatibility. Direct mechanical substitution on existing PCB layouts is not possible without redesign.

Contact Finish: The 1894969 features tin contact mating finish; the 1844921 features gold. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1844921 be used as a direct replacement for the 1894969 on existing PCBs?

A: No. The pitch difference (2.50mm vs. 2.54mm) creates mechanical incompatibility with existing through-hole patterns. PCB redesign is required for substitution.

Q: What is the significance of the pitch difference between these parts?

A: Pitch defines the center-to-center spacing between adjacent contact positions. A 0.04mm difference, while small, prevents mechanical alignment with mating connectors and PCB footprints designed for the original 2.50mm specification.

Q: Are the electrical ratings of the 1844921 suitable for applications designed for the 1894969?

A: The 1844921 provides higher current capacity (6A vs. 4A), which is advantageous. However, voltage ratings differ. The 1894969 supports higher IEC voltage (320V vs. 160V). Application voltage requirements must be verified against the substitute part's 160V IEC / 150V UL ratings.

Q: What is the difference between tin and gold contact finishes?

A: Tin provides basic corrosion resistance and is suitable for standard applications. Gold plating (as used in the 1844921) offers superior corrosion resistance, lower contact resistance, and enhanced reliability in high-reliability or harsh environment applications.

Q: Why is the 1894969 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 1844921, as an active product from the same manufacturer, represents the current product line evolution.

Q: Does the packaging difference (Tape & Reel for 1844921) affect compatibility?

A: Packaging affects procurement and handling but does not impact electrical or mechanical compatibility. Tape & Reel packaging is standard for automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. The 1894969 is RoHS Compliant. The 1844921 is ROHS3 Compliant, representing compliance with the current RoHS 3 directive revision.
