Phoenix Contact 1897131 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897131 is a 6-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 part of the COMBICON EMC series and is classified as obsolete. Due to its obsolete status, identifying compatible substitute parts is essential for ongoing system maintenance, repairs, and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897131 is determined by the following critical parameters:

• Number of Positions and Pitch: Both the main part and substitute must maintain 6 positions at 0.138" (4.60mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Orientation and Mounting Type: The 90° right-angle through-hole configuration must be preserved to maintain form factor compatibility.
• Electrical Ratings: Substitute parts must meet or exceed the IEC and UL voltage and current specifications (250 V IEC / 300 V UL; 8 A minimum).
• Housing Material and Flammability: PBT housing with UL94 V-0 rating ensures compliance with safety and material standards.
• Shrouding Configuration: Four-side shrouding must be maintained for mechanical stability and safety.

The Phoenix Contact 1844252 qualifies as a substitute based on these parameters. While it differs in series designation (COMBICON MC versus COMBICON EMC), termination style (solder versus press-fit), and minor dimensional variations, it maintains all critical functional and electrical parameters required for substitution.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1844252 is the qualified substitute for the obsolete 1897131. Selection should be based on the following factors:

Product Status: The 1844252 holds active product status, ensuring ongoing availability and manufacturer support, whereas the 1897131 is obsolete and subject to supply discontinuation.

Compliance and Certifications: Both parts maintain UL94 V-0 flammability ratings and meet electrical safety standards. The 1844252 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS Compliant designation of the 1897131.

Electrical Performance: The 1844252 provides enhanced current capacity under IEC conditions (12A versus 8A), while maintaining equivalent UL ratings. This represents a performance upgrade suitable for applications requiring higher current handling.

Termination Consideration: The primary difference lies in termination style. The 1897131 uses press-fit termination, while the 1844252 employs solder termination. This distinction requires assessment of PCB design and assembly process compatibility. Press-fit termination eliminates solder reflow, whereas solder termination integrates with standard wave or reflow soldering processes.

Mechanical Compatibility: Both parts maintain identical pitch (0.138" / 4.60mm), position count (6), orientation (90° right angle), and shrouding configuration, ensuring direct mechanical substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 1844252 directly replace the 1897131 in existing designs?

A: Mechanical and electrical compatibility is confirmed. The primary consideration is termination method: the 1897131 uses press-fit termination while the 1844252 uses solder termination. PCB design and assembly process must accommodate solder termination. Pitch, position count, orientation, and electrical ratings are equivalent or superior.

Q: What is the significance of the series change from COMBICON EMC to COMBICON MC?

A: Series designation reflects product line evolution within Phoenix Contact's terminal block portfolio. Both series maintain identical electrical and mechanical specifications for this 6-position, 4.60mm pitch configuration. The change represents a product line update rather than a functional modification.

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

A: Minor dimensional variations exist. The 1844252 has a contact tail length of 0.134" (3.40mm) compared to 0.138" (4.60mm) for the 1897131, and an insulation height of 0.285" (7.25mm) versus 0.276" (7.00mm). These variations are within acceptable tolerances for standard through-hole PCB applications and do not affect functional compatibility.

Q: Does the higher current rating of the 1844252 (12A IEC) affect compatibility?

A: No. Higher current capacity represents a performance upgrade. The 1844252 meets or exceeds all electrical requirements of the 1897131. Applications designed for 8A operation remain fully compatible with the 1844252's 12A IEC rating.

Q: What packaging differences exist between these parts?

A: The 1897131 packaging is listed as unspecified, while the 1844252 is supplied in bulk packaging. Bulk packaging is standard for active production components and does not affect component functionality or electrical performance.

Q: Are both parts RoHS compliant?

A: Yes. The 1897131 carries RoHS Compliant status, while the 1844252 carries ROHS3 Compliant status. Both meet RoHS requirements. ROHS3 represents the current regulatory standard and indicates the 1844252 aligns with current environmental compliance frameworks.
