Phoenix Contact 1897296 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897296 is a 7-position terminal block header with male pins, shrouded on 4 sides, designed for 90° right-angle through-hole mounting. This component operates at 8A (IEC/UL) and 250V (IEC) / 300V (UL) with 4.6mm pitch spacing. The part belongs to the COMBICON EMC series and features press-fit termination with tin-plated contacts and UL94 V-0 rated polybutylene terephthalate housing.

The 1897296 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 Phoenix Contact 1897296 is determined by the following critical parameters:

• Position Count & Pitch: 7 positions at 0.138" (4.6mm) spacing
• Connector Type & Configuration: Male pins, shrouded (4 side), 90° right-angle orientation
• Electrical Ratings: 8A (IEC/UL), 250V (IEC), 300V (UL)
• Mounting Method: Through-hole PCB mounting
• Housing Material & Flammability: PBT with UL94 V-0 rating
• Contact Finish: Tin plating

The Phoenix Contact 1843842 qualifies as a substitute part. It maintains identical position count, pitch, connector type, shrouding configuration, orientation, mounting method, electrical ratings, housing material, flammability rating, and contact finish. The primary difference is the termination style: the 1843842 uses solder termination instead of press-fit, and belongs to the COMBICON MC series rather than COMBICON EMC. Minor dimensional variations exist in contact tail length and insulation height, which do not affect functional compatibility in applications designed for the 1897296.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1843842 is the qualified substitute for the obsolete 1897296. Both parts maintain identical electrical performance (8A/250V IEC, 8A/300V UL), mechanical configuration (7-position, 4.6mm pitch, 90° right-angle, shrouded male header), and material specifications (PBT housing, UL94 V-0 flammability rating).

The 1843842 is currently in active production status, ensuring long-term availability and supply chain continuity. It carries ROHS3 compliance, meeting current regulatory requirements. The transition from press-fit to solder termination requires PCB design modification to accommodate solder pads instead of press-fit holes; however, the electrical and mechanical interface remains functionally equivalent.

Minor dimensional differences in contact tail length (0.134" vs. 0.138") and insulation height (0.285" vs. 0.276") are within acceptable tolerances for standard through-hole PCB applications and do not compromise functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1843842 directly replace the 1897296 without PCB modification?

A: No. The primary difference is termination style: the 1897296 uses press-fit termination while the 1843842 uses solder termination. PCB footprints must be redesigned to accommodate solder pads instead of press-fit holes. Electrical and mechanical performance remain equivalent.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts operate at 8A (IEC/UL) and 250V (IEC) / 300V (UL). Current and voltage specifications are identical.

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

A: The series designation reflects product line evolution within Phoenix Contact's terminal block portfolio. The COMBICON MC series represents the current active product line, while COMBICON EMC is obsolete. Functional specifications remain equivalent.

Q: Do the dimensional differences affect compatibility?

A: The contact tail length difference (0.138" to 0.134") and insulation height difference (0.276" to 0.285") are minor and do not affect standard through-hole PCB applications. These variations fall within acceptable manufacturing tolerances for connector interfaces.

Q: Is the 1843842 compliant with current environmental regulations?

A: Yes. The 1843842 carries ROHS3 compliance and is classified as REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the inventory status of the substitute part?

A: The 1843842 is in active production with 1012 pieces available in new original stock, ensuring reliable supply chain availability compared to the obsolete 1897296.
