Phoenix Contact 1897241 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897241 is a 2-position terminal block header with male pins, shrouded design, and 90° right-angle orientation. It features a 0.138" (4.60mm) pitch and is rated for 8A at 250V (IEC) or 300V (UL). The part is mounted through-hole with press-fit termination and is housed in UL94 V-0 rated polybutylene terephthalate (PBT).

The 1897241 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1897241 is determined by strict alignment of the following parameters:

• Position count and pitch: Both main and substitute parts must have 2 positions at 0.138" (4.60mm) spacing
• Connector type and orientation: Both must be male pin headers with 90° right-angle, shrouded (4-side) design
• Electrical ratings: Current and voltage ratings must meet or exceed IEC 8A/250V and UL 8A/300V
• Mounting method: Through-hole mounting is required
• Housing material and flammability: PBT housing with UL94 V-0 rating ensures mechanical and thermal compatibility
• Contact finish: Tin plating on mating surfaces ensures consistent contact resistance

The Phoenix Contact 1843790 meets all substitution criteria. The primary difference is termination style: the 1897241 uses press-fit termination, while the 1843790 uses solder termination. Minor dimensional variations in contact tail length and insulation height fall within acceptable mechanical tolerances for connector mating.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843790 is the qualified substitute for the obsolete 1897241. Both parts share identical electrical ratings, connector geometry, and housing specifications. The 1843790 carries active product status with higher inventory availability (9601 units in stock versus 659 units for the 1897241).

The primary design consideration is termination method. The 1897241 uses press-fit termination for automated assembly, while the 1843790 requires solder termination. This difference necessitates PCB design modification: press-fit designs use plated through-holes with specific diameter tolerances, whereas solder designs use standard through-hole pads. Manufacturing process compatibility must be evaluated during design transition.

Both parts meet current RoHS and REACH compliance requirements. The 1843790 carries ROHS3 certification, indicating compliance with the latest regulatory standards. Moisture sensitivity level (MSL 1) is identical for both parts, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1843790 directly replace the 1897241 without PCB modification?

A: Electrical and mechanical compatibility is confirmed. However, termination method differs: the 1897241 uses press-fit termination while the 1843790 uses solder termination. PCB pad design and assembly process must be adapted accordingly. Direct socket-level substitution is not possible without design changes.

Q: Are the dimensional differences between the two parts significant?

A: Contact tail length differs by 0.004" (0.10mm) and insulation height by 0.009" (0.25mm). These variations are within standard connector manufacturing tolerances and do not affect mating performance or electrical function. Mechanical clearance in the application should be verified during design review.

Q: What is the difference between COMBICON EMC and COMBICON MC series?

A: Both are Phoenix Contact COMBICON terminal block families. The EMC series (1897241) is obsolete. The MC series (1843790) is the current production line with active status and improved availability. Electrical and mechanical specifications are equivalent.

Q: Are there any compliance differences between the two parts?

A: Both parts are UL94 V-0 rated and meet RoHS requirements. The 1843790 carries ROHS3 certification, representing the latest regulatory compliance standard. Both are classified as EAR99 for export control purposes.

Q: What inventory considerations apply to this substitution?

A: The 1897241 has 659 units in stock with obsolete status. The 1843790 has 9601 units available with active product status. For new designs or long-term production, the 1843790 is the recommended choice to ensure supply chain continuity.
