Phoenix Contact 1897238 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897238 is a 16-position terminal block header with male pins, shrouded on four sides, featuring 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) / 8A (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 1897238 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 16
• Pitch: 0.138" (4.60mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Housing material: Polybutylene Terephthalate (PBT)
• Material flammability rating: UL94 V-0

Electrical Compatibility Parameters:

• Current rating must meet or exceed 8A (IEC)
• Voltage rating must meet or exceed 250V (IEC) and 300V (UL)

Allowable Variations:

• Termination style may differ (press-fit to solder transition acceptable)
• Contact tail length and insulation height may vary within mechanical tolerance
• Series designation may differ (COMBICON EMC to COMBICON MC acceptable)
• Product status may transition from obsolete to active

The Phoenix Contact 1844359 qualifies as a substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844359 is a qualified substitute for the obsolete 1897238 based on electrical and mechanical parameter alignment. Key considerations for selection:

Electrical Performance: The 1844359 provides enhanced current capacity (12A IEC versus 8A IEC), exceeding the original specification while maintaining identical voltage ratings. This represents a performance upgrade with no derating required.

Compliance Status: The 1844359 carries active product status with ROHS3 compliance, compared to the obsolete status of the 1897238. Both components maintain UL94 V-0 flammability rating and identical ECCN/HTSUS classifications, ensuring regulatory consistency.

Termination Transition: The primary difference is termination style—the 1844359 uses solder termination versus the press-fit design of the 1897238. This requires assembly process modification but does not affect electrical or mechanical compatibility.

Mechanical Compatibility: Minor dimensional variations exist (contact tail length 0.134" versus 0.138"; insulation height 0.285" versus 0.276"), remaining within acceptable mechanical tolerance for through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1844359 directly replace the 1897238 in existing designs?

A: Electrical and mechanical compatibility is confirmed. The primary consideration is termination method—the 1844359 requires solder attachment rather than press-fit insertion. PCB design and assembly processes must accommodate this change.

Q: What is the significance of the current rating difference (12A versus 8A)?

A: The 1844359 provides higher current capacity, making it suitable for applications requiring the original 8A specification and applications with higher current demands up to 12A. No derating is necessary for 8A applications.

Q: Are there packaging differences between these parts?

A: The 1897238 is listed with unspecified packaging, while the 1844359 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the product status change from obsolete to active affect compatibility?

A: No. The active status of the 1844359 ensures continued availability and supply chain stability, while maintaining full electrical and mechanical compatibility with the original specification.

Q: Are both parts RoHS compliant?

A: Yes. The 1897238 is RoHS Compliant, and the 1844359 is ROHS3 Compliant. Both meet current environmental regulations.
