Phoenix Contact 1897335 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897335 is an 11-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 UL94 V-0 flammability rating and RoHS compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897335 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed IEC 8A / 250V and UL 8A / 300V specifications
• Physical Configuration: 11-position count, 0.138" (4.60mm) pitch, and 90° right-angle orientation are mandatory
• Connector Type: Male pins with four-side shrouding required for mechanical and electrical safety
• Mounting Method: Through-hole mounting compatibility
• Material and Compliance: PBT housing with UL94 V-0 flammability rating and RoHS compliance

The identified substitute part, Phoenix Contact 1843884, satisfies all critical electrical and mechanical parameters. The primary difference lies in the termination style (solder versus press-fit) and minor dimensional variations in contact tail length and insulation height, which do not affect functional compatibility in applications where the connector footprint and electrical performance are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843884 is the primary substitute for the obsolete 1897335 terminal block header. Selection of this substitute is supported by the following factors:

Product Status: The 1843884 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 1897335.

Electrical Equivalence: Both parts maintain identical current and voltage ratings (8A IEC, 250V IEC, 8A UL, 300V UL), ensuring direct electrical compatibility in existing circuit designs.

Mechanical Compatibility: Identical pitch (0.138" / 4.60mm), position count (11), orientation (90° right-angle), and connector type (male pins, four-side shrouded) confirm mechanical interchangeability on standard PCB layouts.

Compliance and Safety: Both parts feature UL94 V-0 flammability rating, tin contact mating finish, and PBT housing material. The 1843884 carries ROHS3 compliance, representing current regulatory alignment.

Termination Consideration: The primary design difference is termination style—the 1897335 uses press-fit termination while the 1843884 uses solder termination. This difference requires PCB design modification but does not affect electrical performance or connector functionality.

Frequently Asked Questions (FAQ)

Q: Can the 1843884 directly replace the 1897335 without PCB modification?

A: Electrical and mechanical compatibility is confirmed. However, the termination style differs (press-fit versus solder), requiring PCB pad redesign. The connector footprint and electrical performance remain equivalent.

Q: Are the dimensional differences between contact tail length and insulation height significant?

A: The contact tail length difference (0.138" versus 0.134") and insulation height difference (0.276" versus 0.285") are minor and fall within standard manufacturing tolerances for this connector category. These variations do not affect functional compatibility in standard through-hole applications.

Q: What is the impact of switching from COMBICON EMC to COMBICON MC series?

A: Both series maintain identical electrical ratings, safety certifications, and material specifications. The series designation reflects product line organization; functional performance remains equivalent.

Q: Is the 1843884 suitable for applications requiring press-fit termination?

A: No. The 1843884 is designed for solder termination only. If press-fit termination is a design requirement, alternative parts within the COMBICON EMC series should be evaluated.

Q: Are there compliance differences between RoHS and ROHS3?

A: ROHS3 represents the current regulatory standard with updated substance restrictions. Both certifications confirm RoHS compliance; ROHS3 indicates alignment with current EU regulations.
