Phoenix Contact 1827444 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1827444 is a 4-position terminal block header with male pins, shrouded design, and 0.150" (3.81mm) pitch orientation at 45°. This component is part of the COMBICON SMC series and is designed for through-hole solder termination applications requiring 8A current capacity at 320V (IEC) or 300V (UL). The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical ratings, mechanical configuration, and compliance certifications align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1827444 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current rating (8A IEC/UL) and voltage rating (320V IEC / 300V UL) must match exactly
• Mechanical Configuration: 4-position count, 0.150" (3.81mm) pitch, 45° header orientation, male pins with 4-side shrouding
• Termination & Mounting: Solder termination and through-hole mounting type
• Material & Compliance: Polyamide housing, UL94 V-0 flammability rating, RoHS compliance, and tin contact finish

The substitute part 1827295 meets all these criteria and is classified as a direct equivalent within the COMBICON SMC series.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1827444 and 1827295 are active production components within the COMBICON SMC terminal block header series. The parts are electrically and mechanically equivalent across all specified parameters. The 1827295 carries ROHS3 compliance certification, which represents an updated regulatory status relative to the standard RoHS designation on the 1827444. Both components meet UL94 V-0 flammability requirements and maintain unlimited moisture sensitivity rating (MSL 1). Selection between these parts should be based on inventory availability and compliance documentation requirements for the end application. The 1827295 currently maintains higher inventory levels (1204 pcs vs. 776 pcs).

Frequently Asked Questions (FAQ)

Q: Are the Phoenix Contact 1827444 and 1827295 pin-compatible? A: Yes. Both parts feature identical 4-position configuration, 0.150" (3.81mm) pitch, 45° orientation, and male pin shrouding. PCB footprints and mating connector compatibility are identical.

Q: Can I substitute 1827295 for 1827444 in existing designs? A: Yes. The parts are direct equivalents with matching electrical ratings (8A at 320V IEC), mechanical dimensions, and termination method. No design modification is required.

Q: What is the difference between RoHS and ROHS3 compliance? A: ROHS3 represents the current regulatory designation under the Restriction of Hazardous Substances Directive. Both designations indicate compliance with hazardous substance restrictions. The 1827295 carries the updated ROHS3 certification.

Q: Are both parts suitable for high-temperature applications? A: Operating temperature specifications are not provided in the technical data for either part. Consult Phoenix Contact datasheets for thermal performance limits.

Q: What is the significance of the UL94 V-0 rating? A: UL94 V-0 indicates the housing material meets the highest flammability classification, meaning the material extinguishes within 10 seconds after flame removal and produces no flaming drips.

Q: Can these terminal blocks be used in UL-listed equipment? A: Both parts carry UL certification with 8A at 300V rating. Compliance with specific UL equipment standards depends on the complete assembly design and application context.

Q: What does MSL 1 (Unlimited) mean for storage? A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions. No special moisture control or baking procedures are required prior to soldering.
