Phoenix Contact 1897034 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897034 is an 11-position terminal block header with male pins, shrouded on four sides, designed for 0.150" (3.81mm) pitch right-angle through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL), with tin-plated contacts and UL94 V-0 rated housing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897034 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (8A IEC/UL), voltage rating (250V IEC / 300V UL), and contact mating finish (tin)
• Mechanical Compatibility: 11-position configuration, 0.150" (3.81mm) pitch, 90° right-angle orientation, through-hole mounting, and four-sided shrouding
• Material & Safety Compliance: PBT housing material, UL94 V-0 flammability rating, and RoHS compliance status

The substitute part Phoenix Contact 1827952 meets all these critical parameters. Differences in termination style (press-fit vs. solder), series designation (COMBICON EMC vs. COMBICON MC), and minor dimensional variations in contact tail length and insulation height do not preclude functional substitution when electrical and mechanical requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1827952 is the qualified substitute for the obsolete 1897034. Both parts maintain identical electrical ratings (8A/250V IEC, 8A/300V UL) and mechanical configuration (11-position, 3.81mm pitch, right-angle through-hole). The primary distinction is termination method: the 1897034 uses press-fit termination while the 1827952 employs solder termination. This difference requires PCB design adjustment but does not affect electrical performance or safety compliance.

The 1827952 carries active product status with ROHS3 compliance, providing superior long-term availability compared to the obsolete 1897034. Both parts feature identical housing material (PBT) and flammability rating (UL94 V-0), ensuring equivalent safety performance in target applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1827952 directly replace 1897034 on existing PCBs?

A: Direct PCB replacement requires design verification. The 1897034 uses press-fit termination (through-hole pins designed for mechanical insertion), while the 1827952 uses solder termination. PCB pad patterns and hole sizing differ between these termination methods. Mechanical fit is compatible, but soldering process parameters must be applied for the 1827952.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts are rated 8A (IEC/UL) and 250V (IEC) / 300V (UL) with tin-plated contacts. Electrical performance and safety margins are equivalent.

Q: What is the significance of the contact tail length difference (0.138" vs. 0.134")?

A: The 0.004" (0.10mm) difference in contact tail length is within normal manufacturing tolerance and does not affect functional compatibility. Both parts are designed for through-hole mounting with equivalent mechanical engagement.

Q: Does the insulation height difference affect compatibility?

A: The insulation height difference (0.276" vs. 0.285") reflects design variations between the COMBICON EMC and COMBICON MC series. This parameter does not affect electrical performance or mechanical fit in standard applications. Verify clearance in space-constrained designs.

Q: Why is 1897034 obsolete while 1827952 remains active?

A: Product lifecycle management by Phoenix Contact has transitioned the COMBICON EMC series (1897034) to obsolete status while maintaining the COMBICON MC series (1827952) as the current production line. The 1827952 represents the active equivalent for new designs and ongoing procurement.

Q: Are both parts RoHS compliant?

A: Yes. The 1897034 is RoHS Compliant, and the 1827952 is ROHS3 Compliant. Both meet current environmental regulations for electronic component manufacturing.
