Phoenix Contact 1897377 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897377 is a 15-position terminal block header with male pins, shrouded on four sides, featuring a 0.138" (4.60mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 8A (IEC/UL) and 250V (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 1897377 is determined by the following critical parameters:

Electrical Compatibility:

• Current rating: 8A (IEC and UL)
• Voltage rating: 250V (IEC) / 300V (UL)

Mechanical Compatibility:

• Number of positions: 15
• Pitch: 0.138" (4.60mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole

Material & Compliance:

• Housing material: Polybutylene Terephthalate (PBT)
• Flammability rating: UL94 V-0
• RoHS compliance required

The substitute part 1843923 maintains electrical and mechanical compatibility across all critical parameters. The primary difference lies in termination style (solder versus press-fit) and minor dimensional variations in contact tail length and insulation height, which do not affect functional substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843923 is a direct functional substitute for the obsolete 1897377. Both components share identical electrical ratings (8A/250V IEC, 8A/300V UL), mechanical configuration (15 positions, 4.60mm pitch, 90° right-angle), and material specifications (PBT housing, UL94 V-0 rating).

The 1843923 offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts maintain RoHS compliance and MSL 1 classification, supporting modern manufacturing and environmental standards.

The termination method difference (press-fit versus solder) requires board-level design consideration. Press-fit termination (1897377) provides tool-free installation, while solder termination (1843923) requires reflow or wave soldering processes. This distinction does not affect electrical or mechanical compatibility but impacts assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can the 1843923 directly replace the 1897377 in existing designs?

A: Electrical and mechanical compatibility is confirmed across all critical parameters. The primary consideration is termination method: the 1843923 requires solder attachment rather than press-fit insertion. PCB design must accommodate solder pads instead of press-fit holes.

Q: What is the significance of the series designation change (COMBICON EMC to COMBICON MC)?

A: Series designation reflects product line evolution within Phoenix Contact's terminal block portfolio. Both series maintain identical electrical ratings, mechanical dimensions, and compliance certifications relevant to substitution.

Q: Are there dimensional differences that affect PCB layout?

A: Minor variations exist in contact tail length (0.138" versus 0.134") and insulation height (0.276" versus 0.285"). These differences are within typical manufacturing tolerances and do not affect functional compatibility or standard PCB footprint design.

Q: Does the 1843923 maintain the same shrouded configuration?

A: Yes. Both parts feature four-side shrouding, identical pitch spacing (4.60mm), and 90° right-angle orientation. Mechanical envelope compatibility is confirmed.

Q: What packaging is available for the 1843923?

A: The 1843923 is supplied in bulk packaging, with 715 pieces currently in stock as new original inventory.
