Phoenix Contact 1755260 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1755260 is a 4-position vertical terminal block header with male pins, shrouded on two sides, featuring a 5.00mm pitch. This component is designed for through-hole solder mounting and operates at 12A (IEC) / 12A (UL) and 250V (IEC) / 300V (UL). The part is active in production and RoHS compliant. Substitute parts are necessary when the primary part is unavailable, when alternative compliance certifications are required, or when design specifications allow for compatible pitch variations and electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1755260 is determined by the following critical parameters:

• Number of Positions and Pitch: All substitute parts must maintain 4 positions. Pitch tolerance allows for 5.00mm (0.197") and 5.08mm (0.200") variants, as these are standard metric and imperial equivalents within acceptable mechanical compatibility ranges for terminal block applications.
• Type and Shrouding: Substitute parts must be header-type connectors with male pins. Shrouding configuration (2-side or 4-side) affects mechanical fit; 2-side shrouded parts are direct equivalents, while 4-side shrouded parts represent a design variation.
• Mounting and Termination: All substitutes must support through-hole mounting with solder termination.
• Electrical Ratings: Substitute parts must meet or exceed the IEC/UL voltage requirement of 250V/300V. Current ratings of 12A or higher are acceptable; lower ratings are not suitable.
• Compliance: RoHS compliance and UL94 V-0 flammability rating are required for equivalent substitution.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred Substitutes)

TE Connectivity 282822-4 and Würth Elektronik 691311700004 are the closest functional equivalents to the Phoenix Contact 1755260. Both maintain the 4-position configuration, vertical orientation, 2-side shrouding, and solder through-hole mounting. The 282822-4 matches the exact 5.00mm pitch, while the 691311700004 also uses 5.00mm pitch. Both parts exceed the minimum electrical requirements with 15A and 20A UL ratings respectively, and both carry UL94 V-0 and RoHS compliance certifications. The 282822-4 operates to 110°C, while the 691311700004 operates to 105°C.

Pitch-Compatible Alternatives

TE Connectivity 282825-4 and Würth Elektronik 691311500004 use a 5.08mm pitch instead of 5.00mm. This 0.08mm difference is within standard tolerance for terminal block applications and represents a metric-to-imperial conversion. Both parts maintain 4 positions, vertical orientation, 2-side shrouding, and solder mounting. Both exceed electrical requirements and carry required compliance certifications.

Design Variation (4-Side Shrouding)

Amphenol PCD ELFH04250 uses 4-side shrouding instead of 2-side, which affects mechanical fit and board layout. This part uses 5.08mm pitch and meets electrical and compliance requirements but represents a design change requiring PCB layout verification.

Limited Compatibility

On Shore Technology OSTOQ045350 has incomplete specification data (flammability rating and termination style not specified), making it unsuitable as a primary substitute without additional verification.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 5.08mm pitch part for the 5.00mm Phoenix Contact 1755260?

A: Yes, within design tolerance. The 0.08mm pitch difference is acceptable for terminal block applications. However, verify that your PCB layout accommodates this variation. TE Connectivity 282825-4 and Würth Elektronik 691311500004 are both qualified 5.08mm alternatives.

Q: What is the difference between 2-side and 4-side shrouding?

A: 2-side shrouding provides lateral protection on two opposing sides, while 4-side shrouding surrounds all four sides. The Amphenol PCD ELFH04250 offers 4-side shrouding but requires PCB layout verification due to different mechanical dimensions.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitutes carry either RoHS or ROHS3 compliance certification, meeting current environmental regulations.

Q: Do substitute parts meet the same voltage and current ratings?

A: All substitutes meet or exceed the 300V UL voltage requirement. Current ratings vary: TE Connectivity parts provide 15A, Würth Elektronik parts provide 20A, and Amphenol provides 15A. All exceed the 12A requirement of the original part.

Q: What is the operating temperature range of substitute parts?

A: TE Connectivity parts operate from -40°C to 110°C, Würth Elektronik and Amphenol parts operate from -40°C to 105°C, and On Shore Technology operates from -30°C to 105°C. Verify your application requirements against these ranges.

Q: Can I use OSTOQ045350 as a substitute?

A: OSTOQ045350 has incomplete technical specifications (flammability rating and termination style are not specified). Use only if additional verification confirms compatibility with your application requirements.

Q: Which substitute offers the best current capacity?

A: Würth Elektronik 691311500004 and 691311700004 both provide 20A UL current rating, the highest among all listed substitutes.
