Phoenix Contact 1914920 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1914920 is a 9-position terminal block header with male pins, featuring a shrouded 4-side design and 0.197" (5.00mm) pitch for vertical through-hole mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part operates at 12A (IEC) / 12A (UL) and 320V (IEC) / 300V (UL), with press-fit termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1914920 is determined by the following critical parameters:

Core Compatibility Requirements:

• Number of positions: 9
• Pitch: 0.197" (5.00mm)
• Type: Header, Male Pins, Shrouded (4 Side)
• Header orientation: Vertical
• Mounting type: Through Hole
• Electrical ratings: Minimum 12A (IEC) and 320V (IEC)
• Flammability rating: UL94 V-0

Identified Substitutes:

1755587 qualifies as a substitute with matching core parameters (9 positions, 5.00mm pitch, vertical through-hole, shrouded male pins). This part is active and maintains electrical compatibility with 12A (IEC) and 400V (IEC) ratings, exceeding the original voltage specification. The primary difference is termination style (solder vs. press-fit) and housing material (Polyamide/Nylon vs. PBT).

1837093 qualifies as a substitute with matching core parameters (9 positions, 5.00mm pitch, vertical through-hole, shrouded male pins). This part is active and maintains electrical compatibility with 12A (IEC) and 320V (IEC) ratings. Differences include termination style (solder vs. press-fit), housing material (Liquid Crystal Polymer vs. PBT), color (black vs. green), and contact tail length (0.079" vs. 0.154").

Parameter Comparison

Engineering Selection Recommendations

1755587 is recommended for applications where the original press-fit termination can be replaced with solder termination. This part is active and maintains full electrical compatibility with enhanced voltage rating (400V IEC). The Polyamide housing material and matching contact tail length (3.90mm) provide direct mechanical compatibility with existing PCB layouts. RoHS3 compliance and MSL 1 rating support modern manufacturing environments.

1837093 is recommended for applications where solder termination is acceptable and where the shorter contact tail length (2.00mm) accommodates the PCB design. This part is active with enhanced UL current rating (16A) and operating temperature range (-40°C to 100°C). The Liquid Crystal Polymer housing provides superior thermal and chemical resistance. Note that the black color and shorter contact tail represent design differences requiring PCB layout verification.

Both substitutes maintain the critical 9-position, 5.00mm pitch, vertical through-hole configuration with shrouded male pins and UL94 V-0 flammability rating. Selection between substitutes depends on termination method compatibility and mechanical fit requirements.

Frequently Asked Questions (FAQ)

Q: Can 1755587 or 1837093 directly replace the 1914920 without PCB modification?

A: Both parts maintain the same 9-position count, 5.00mm pitch, vertical orientation, and insulation height (12.00mm). However, the termination style differs (solder vs. press-fit), requiring soldering instead of press-fit insertion. The 1837093 has a shorter contact tail (2.00mm vs. 3.90mm), which may require PCB layout verification.

Q: Are there electrical rating differences between the main part and substitutes?

A: The 1914920 operates at 12A/320V (IEC) and 12A/300V (UL). The 1755587 exceeds these ratings at 12A/400V (IEC) and 12A/300V (UL). The 1837093 matches IEC ratings (12A/320V) but exceeds UL current rating (16A vs. 12A). Both substitutes are electrically compatible.

Q: What are the housing material differences, and do they affect performance?

A: The 1914920 uses Polybutylene Terephthalate (PBT). The 1755587 uses Polyamide (PA/Nylon), and the 1837093 uses Liquid Crystal Polymer (LCP). All three materials carry UL94 V-0 flammability rating. Material selection affects thermal and chemical resistance but does not impact electrical compatibility for standard applications.

Q: Does the color difference between parts affect functionality?

A: No. The 1914920 and 1755587 are green; the 1837093 is black. Color is a visual identifier only and does not affect electrical or mechanical performance.

Q: Which substitute is preferred for new designs?

A: Both 1755587 and 1837093 are active products. Selection depends on termination method (solder compatibility), mechanical fit (contact tail length), and environmental requirements (operating temperature range). The 1837093 offers the widest operating temperature range (-40°C to 100°C).

Q: Are compliance certifications equivalent across all three parts?

A: All three parts carry UL94 V-0 flammability rating and EAR99 ECCN classification. The 1755587 includes RoHS3 compliance and MSL 1 rating. The 1837093 includes MSL 1 rating. Compliance requirements should be verified against specific application standards.
