Phoenix Contact 1897021 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897021 is a 10-position terminal block header with male pins, shrouded on four sides, featuring 0.150" (3.81mm) pitch and right-angle through-hole mounting. This component is part of the COMBICON EMC series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1897021 is based on strict equivalence of the following critical parameters:

• Number of positions: 10
• Pitch: 0.150" (3.81mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Current rating - IEC: 8A
• Voltage rating - IEC: 250 V
• Current rating - UL: 8 A
• Voltage rating - UL: 300 V
• Housing material: Polybutylene Terephthalate (PBT)
• Material flammability rating: UL94 V-0
• RoHS compliance status

The substitute part Phoenix Contact 1827949 meets all these critical parameters. The primary difference is the termination style (press-fit versus solder) and minor dimensional variations in contact tail length and insulation height, which do not affect functional compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1827949 is the direct substitute for the obsolete 1897021. Selection of this substitute is supported by the following factors:

• The substitute part is in active production status, ensuring long-term availability and supply chain continuity.
• Both parts maintain identical electrical ratings (8A at 250V IEC, 8A at 300V UL) and mechanical compatibility through matching pitch, position count, and mounting configuration.
• The substitute achieves ROHS3 compliance, representing an advancement over the original RoHS Compliant status.
• Both parts share identical housing material (PBT), flammability rating (UL94 V-0), and moisture sensitivity classification (MSL 1).
• The termination style difference (solder versus press-fit) requires PCB design adjustment but does not affect electrical or mechanical performance in equivalent applications.
• Minor dimensional variations in contact tail length (0.004" difference) and insulation height (0.009" difference) are within acceptable tolerances for standard through-hole terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the 1827949 be used as a direct drop-in replacement for the 1897021?

A: The 1827949 is functionally equivalent in electrical and mechanical performance. The primary consideration is the termination style: the 1897021 uses press-fit termination while the 1827949 uses solder termination. PCB design modifications are required to accommodate the solder termination method. Contact tail length and insulation height differences are minor and do not prevent physical mounting.

Q: What is the significance of the termination style difference?

A: Press-fit termination (1897021) requires precision-drilled PCB holes and insertion tooling. Solder termination (1827949) uses standard through-hole soldering processes. The choice depends on manufacturing capability and assembly equipment. Both methods provide equivalent electrical and mechanical connections.

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

A: Both parts meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity classification. The 1827949 achieves ROHS3 compliance, which represents a more current regulatory standard than the original RoHS Compliant status of the 1897021. Both parts carry EAR99 export classification.

Q: What are the inventory implications of using the substitute?

A: The 1897021 is obsolete with limited stock (892 pcs). The 1827949 is in active production with higher availability (1022 pcs in stock). For new designs and ongoing production, the 1827949 is the recommended choice to ensure supply continuity.

Q: Are the dimensional differences between the parts critical?

A: The contact tail length difference (0.138" versus 0.134") and insulation height difference (0.276" versus 0.285") are minor variations typical within terminal block product families. These differences do not affect standard through-hole PCB mounting or connector mating performance.

Q: What packaging considerations apply to the substitute?

A: The 1897021 packaging is listed as unspecified. The 1827949 is supplied in bulk packaging. Confirm bulk packaging specifications with the supplier to ensure compatibility with your receiving and inventory processes.
