Phoenix Contact 1927593 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1927593 is a 5-position terminal block header with male pins, shrouded on 4 sides, designed for 90° right-angle through-hole mounting. This component operates at 12A (IEC) / 15A (UL) and 400V (IEC) / 300V (UL), featuring a 0.200" (5.08mm) pitch and tin-plated contacts. The part is classified as obsolete, making identification of active equivalent components essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1927593 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 5 positions at 0.200" (5.08mm) pitch to ensure PCB footprint compatibility
• Header Configuration: Male pins with 4-side shrouding and 90° right-angle orientation are mandatory for mechanical fit
• Electrical Ratings: IEC and UL current and voltage ratings must meet or exceed the original specification
• Termination & Mounting: Solder termination with through-hole mounting must be preserved
• Material & Compliance: UL94 V-0 flammability rating and RoHS compliance are required

The Phoenix Contact 1954728 qualifies as a direct substitute based on these parameters. Both components share identical position count, pitch, orientation, shrouding configuration, and termination method. Electrical ratings and compliance certifications are equivalent or superior.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1954728 is the active equivalent for the obsolete 1927593 terminal block header. Selection should be based on the following factors:

Product Status: The 1927593 is obsolete, while the 1954728 is active and currently manufactured. For new designs or ongoing procurement, the 1954728 is the appropriate choice.

Electrical Compliance: Both components meet IEC and UL standards. The 1954728 maintains the 12A IEC rating and 400V IEC voltage specification. The UL current rating differs (10A vs. 15A); applications requiring the full 15A UL rating should evaluate circuit requirements against the 10A substitute rating.

Material Composition: The 1954728 uses Liquid Crystal Polymer (LCP) housing instead of Polyamide (PA), providing enhanced thermal and chemical resistance while maintaining UL94 V-0 flammability compliance.

Mechanical Fit: Minor dimensional variations exist in contact tail length (0.114" vs. 0.102") and insulation height (0.350" vs. 0.339"). These differences are within typical PCB design tolerances for through-hole applications but should be verified against specific board layouts.

Compliance & Certification: Both components are RoHS compliant with MSL 1 rating and carry identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the 1954728 directly replace the 1927593 on existing PCBs?

A: The 1954728 shares identical pitch (5.08mm), position count (5), and through-hole termination with the 1927593. PCB footprints designed for the 1927593 will accommodate the 1954728. Minor dimensional differences in contact tail length and insulation height are within standard through-hole tolerances.

Q: What is the difference in UL current rating between these parts?

A: The 1927593 is rated at 15A (UL), while the 1954728 is rated at 10A (UL). Both maintain 12A (IEC) rating. Applications operating at currents between 10A and 15A must be evaluated against the 1954728's 10A UL specification.

Q: Why does the 1954728 use LCP instead of Polyamide?

A: Liquid Crystal Polymer (LCP) provides superior thermal stability and chemical resistance compared to Polyamide. Both materials meet UL94 V-0 flammability requirements. LCP is a material upgrade that enhances component reliability in demanding environments.

Q: Are there packaging differences between these parts?

A: The 1927593 packaging is listed as unspecified, while the 1954728 is supplied in bulk packaging. Verify packaging requirements with your procurement specifications.

Q: Do both parts have the same RoHS and moisture sensitivity compliance?

A: Yes. Both the 1927593 and 1954728 are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level, indicating no special storage or handling requirements.
