Phoenix Contact 1911075 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1911075 is an 8-position terminal block header with male pins, shrouded on four sides, designed for 0.138" (4.60mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

The part operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL), with press-fit termination and PBT housing rated UL94 V-0. RoHS compliance and MSL 1 rating indicate suitability for standard industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1911075 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Current and voltage ratings must match or exceed the original specification (8A IEC, 250V IEC minimum).

Mechanical Compatibility: Number of positions (8), pitch (0.138" / 4.60mm), header orientation (vertical), connector type (male pins, shrouded 4-side), and mounting method (through-hole) must be identical.

Material & Safety Compliance: Housing material (PBT), flammability rating (UL94 V-0), and RoHS compliance status must be maintained.

Termination Consideration: While the original part uses press-fit termination, functionally equivalent alternatives may employ solder termination provided all other parameters remain constant. This represents a design-level substitution suitable for new board layouts or rework scenarios.

The Phoenix Contact 1843664 meets all substitution criteria as an active-status alternative within the COMBICON series family.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The Phoenix Contact 1843664 is the primary substitute for the 1911075. Both components share identical electrical ratings, mechanical dimensions (pitch, position count, orientation), and safety certifications. The 1843664 carries active product status with ROHS3 compliance, providing supply chain continuity and regulatory alignment for new designs or system updates.

Termination Method Consideration: The transition from press-fit (1911075) to solder termination (1843664) requires PCB design modification. Press-fit connections are direct insertion; solder connections require plated through-holes and reflow processing. This substitution is suitable for new board layouts or controlled rework environments where soldering infrastructure is available.

Mechanical Fit: Contact tail length differs slightly (0.150" vs. 0.134"), representing a 0.016" reduction. This minor variation is within typical PCB through-hole tolerance ranges and does not affect functional compatibility. Insulation height remains constant at 0.362".

Compliance & Supply: The 1843664 maintains UL94 V-0 flammability rating and RoHS compliance, ensuring regulatory requirements are met. Active inventory status (4189 pcs) provides reliable sourcing compared to the obsolete 1911075.

Frequently Asked Questions (FAQ)

Q: Can the 1843664 be used as a direct drop-in replacement for the 1911075?

A: Mechanically and electrically, yes. Both components have identical pitch (4.60mm), position count (8), orientation (vertical), and electrical ratings (8A, 250V IEC). The primary difference is termination method: press-fit versus solder. Direct PCB-level substitution requires solder-capable through-holes. For existing press-fit boards, mechanical compatibility exists but assembly method differs.

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

A: The 1911075 has a 0.150" (3.81mm) tail; the 1843664 has a 0.134" (3.40mm) tail. This 0.016" difference is within standard PCB through-hole tolerance and does not affect electrical or mechanical function. For new designs, either specification is acceptable.

Q: Are there any compliance differences between these parts?

A: Both parts meet UL94 V-0 flammability requirements and carry RoHS compliance. The 1843664 specifies ROHS3 compliance, representing a more recent regulatory standard. Both are suitable for applications requiring RoHS certification.

Q: Why is the 1911075 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Phoenix Contact. The 1843664 represents the active product line continuation within the COMBICON series, offering equivalent functionality with current supply availability.

Q: Can I use the 1843664 in applications originally designed for press-fit termination?

A: Functionally, the electrical and mechanical specifications are equivalent. However, assembly method changes from press-fit insertion to solder reflow. This substitution is suitable for new designs or controlled rework scenarios where soldering capability exists. Existing press-fit assembly fixtures cannot be used without modification.

Q: What is the inventory status for these parts?

A: The 1911075 (obsolete) has 1095 pcs in stock. The 1843664 (active) has 4189 pcs in stock, providing superior supply chain availability for ongoing procurement.
