Phoenix Contact 1911240 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1911240 is a 10-position terminal block header with male pins, featuring a shrouded 4-side design and 0.138" (4.60mm) pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations. The part operates at 8A (IEC/UL) and 160V (IEC) / 300V (UL), with press-fit termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1911240 is determined by the following critical parameters:

• Connector Type & Configuration: Header with male pins, shrouded 4-side design
• Position Count & Pitch: 10 positions at 0.138" (4.60mm) pitch
• Mounting & Orientation: Vertical through-hole mounting
• Electrical Ratings: Minimum 8A current capacity and voltage compatibility (IEC 160V minimum, UL 300V)
• Housing Material & Flammability: PBT with UL94 V-0 rating
• Color Specification: Green housing

The Phoenix Contact 1843305 qualifies as a direct substitute based on matching all critical parameters. While termination style differs (solder vs. press-fit), both achieve equivalent electrical and mechanical performance within the specified parameter envelope.

Engineering Selection Recommendations

The Phoenix Contact 1843305 is the qualified substitute for the obsolete 1911240. Selection rationale is based on the following factors:

Product Status: The 1843305 maintains active product status with current manufacturing support, whereas the 1911240 is obsolete. This ensures long-term availability and supply chain continuity.

Electrical Compliance: Both parts meet or exceed the required electrical specifications. The 1843305 provides enhanced IEC voltage rating (250V vs. 160V), maintaining full compatibility with UL ratings (300V for both).

Mechanical & Material Compatibility: Identical connector geometry, pitch, position count, and housing material (PBT UL94 V-0) ensure direct mechanical interchangeability in through-hole PCB applications.

Termination Consideration: The transition from press-fit to solder termination requires PCB design verification. Press-fit termination eliminates solder reflow, while solder termination requires standard wave or reflow soldering processes. Both methods achieve equivalent electrical performance within the specified parameter range.

Compliance & Certifications: Both parts carry identical flammability ratings and material certifications, supporting use in equivalent application environments.

Frequently Asked Questions (FAQ)

Q: Can the 1843305 directly replace the 1911240 in existing designs?

A: Mechanical and electrical compatibility is confirmed. The primary consideration is termination method: the 1911240 uses press-fit termination while the 1843305 uses solder termination. PCB pad design and assembly process must accommodate solder termination. Electrical performance remains equivalent within specified parameters.

Q: What is the difference between press-fit and solder termination?

A: Press-fit termination inserts pins directly into plated through-holes without solder, eliminating reflow exposure. Solder termination requires standard wave or reflow soldering. Both achieve equivalent electrical connection and current-carrying capacity (8A) within the specified voltage range.

Q: Are there voltage rating differences between these parts?

A: The 1843305 provides higher IEC voltage rating (250V vs. 160V). Both parts meet the UL requirement of 300V. The 1843305 offers enhanced voltage margin and is suitable for applications requiring either rating.

Q: What packaging differences exist?

A: The 1911240 was supplied in standard packaging (status not specified). The 1843305 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Is the 1843305 RoHS and REACH compliant?

A: The 1843305 is ROHS3 compliant and REACH unaffected. Compliance documentation should be verified with the manufacturer for specific application requirements.

Q: Can I use the 1843305 in high-reliability or aerospace applications?

A: Both parts carry UL94 V-0 flammability certification. Aerospace or high-reliability applications require verification against specific qualification standards (AS9100, MIL-PRF, etc.). Consult application-specific requirements and manufacturer documentation.
