Phoenix Contact 1955905 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1955905 is a 7-position terminal block header with male pins, shrouded on 4 sides, featuring a 0.200" (5.08mm) pitch and vertical through-hole mounting. This component is part of the COMBICON CCVA series and is actively manufactured. Alternative equivalent parts may be required due to supply chain considerations, manufacturing lead times, or specific application requirements where substitute specifications align with the original design parameters.

Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the Phoenix Contact 1955905 is determined by strict alignment of the following critical parameters:

• Electrical Compatibility: 7 positions, 0.200" (5.08mm) pitch, 300 V UL rating, male pin configuration
• Mechanical Compatibility: Vertical orientation, shrouded (4 side) design, 0.472" (12.00mm) insulation height
• Regulatory Compliance: RoHS compliance status and MSL rating of 1 (Unlimited)

The substitute parts EDSTLZ955/7 and OSTOQ075450 meet these core substitution criteria. Both maintain the same electrical pitch, position count, voltage rating, and regulatory compliance. Differences in mounting type (solder vs. through-hole), housing material, and contact tail length represent design variations that do not preclude functional equivalence when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet RoHS compliance requirements with MSL rating of 1. The Phoenix Contact 1955905 and On Shore OSTOQ075450 share identical insulation height (0.472" / 12.00mm), making OSTOQ075450 the closest mechanical equivalent. The EDSTLZ955/7 exhibits reduced insulation height (0.154" / 3.90mm), which may affect mechanical fit in applications with specific PCB clearance requirements.

Contact tail length variations (2.60mm, 3.90mm, and 4.00mm respectively) reflect manufacturing differences and should be evaluated against specific solder joint and mechanical stress requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can EDSTLZ955/7 be used as a direct replacement for Phoenix Contact 1955905?

A: EDSTLZ955/7 maintains electrical equivalence (7 positions, 5.08mm pitch, 300V UL rating, male pins, shrouded design). However, the insulation height differs significantly (3.90mm vs. 12.00mm), which may impact mechanical fit and clearance in applications with specific PCB layout constraints.

Q: What is the primary difference between OSTOQ075450 and EDSTLZ955/7?

A: Both are On Shore Technology products with identical electrical specifications. OSTOQ075450 matches the Phoenix Contact 1955905 insulation height (12.00mm), while EDSTLZ955/7 has reduced insulation height (3.90mm). OSTOQ075450 specifies brass contact material and thermoplastic housing, whereas EDSTLZ955/7 uses polyamide housing.

Q: Are all three parts RoHS compliant?

A: Yes. Phoenix Contact 1955905 is RoHS Compliant. Both On Shore parts (EDSTLZ955/7 and OSTOQ075450) are ROHS3 Compliant, meeting current regulatory requirements.

Q: Does mounting type affect substitution eligibility?

A: The Phoenix Contact 1955905 uses through-hole mounting, while both On Shore substitutes specify solder mounting. This represents a design variation that requires application-level evaluation. Electrical and mechanical parameters remain compatible; however, PCB assembly process and mechanical stress distribution may differ.

Q: What inventory levels are available for each part?

A: Phoenix Contact 1955905 has 630 pcs in stock. EDSTLZ955/7 has 2040 pcs available. OSTOQ075450 has 6885 pcs available.
