Würth Elektronik 691312710004 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 691312710004 is a 4-position terminal block header with male pins, shrouded on two sides, featuring a 90° right-angle orientation and 5.00mm pitch. This component is designed for through-hole solder termination in industrial control and power distribution applications. The part is currently active in production with 1267 units in stock. Substitute parts may be required due to supply chain constraints, regional availability, or design flexibility within electrical and mechanical tolerance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Würth Elektronik 691312710004 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must maintain 4 positions with pitch tolerance within 5.00mm to 5.08mm, ensuring mechanical compatibility with mating connectors and PCB layouts.
• Header Orientation & Type: Substitutes must be 90° right-angle headers with male pins and two-side shrouding to maintain the same form factor and polarization.
• Termination & Mounting: Solder termination and through-hole mounting are required for assembly process compatibility.
• Electrical Ratings: Substitute parts must meet or exceed the UL voltage rating of 300 V. Current ratings of 15 A (Phoenix Contact substitutes) are acceptable as they remain within the operational envelope for typical terminal block applications, though the original part's 20 A rating provides additional margin.
• Material & Compliance: Housing material may vary between PBT and Polyamide (PA/Nylon), both meeting UL94 V-0 flammability requirements. RoHS3 compliance is mandatory.

The two Phoenix Contact parts listed (1754478 and 1759033) meet these criteria with minor pitch variation (5.08mm vs. 5.00mm) that remains within standard mechanical tolerance for terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

Both Phoenix Contact substitutes (1754478 and 1759033) are active production parts with full RoHS3 compliance and UL94 V-0 flammability certification, meeting the regulatory requirements of the original Würth Elektronik component.

1754478 (Phoenix Contact COMBICON MSTB): This part maintains exact pitch compatibility at 5.00mm and identical electrical ratings under UL standards (300 V, 15 A). The housing material differs (Polyamide vs. PBT), but both materials satisfy UL94 V-0 requirements. Contact tail length is 0.138" (4.60mm) compared to the original 0.157" (4.00mm), requiring PCB layout verification for solder pad depth compatibility.

1759033 (Phoenix Contact COMBICON MSTB): This part features a 5.08mm pitch, representing a 0.08mm deviation from the original 5.00mm specification. This minor pitch variation remains within standard mechanical tolerance for terminal block applications and does not affect electrical performance. Like 1754478, it uses Polyamide housing and has a 0.138" (4.60mm) contact tail length.

Both substitutes provide higher IEC voltage ratings (400 V) than required, offering additional design margin. All three parts are currently in active production with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1754478 be used as a direct replacement for Würth Elektronik 691312710004?

A: Yes, within mechanical constraints. The 1754478 maintains identical pitch (5.00mm) and electrical ratings (300 V UL, 15 A UL). The primary consideration is contact tail length: 0.138" (4.60mm) versus the original 0.157" (4.00mm). PCB solder pad depth must accommodate this 0.019" difference. Housing material differs (Polyamide vs. PBT), but both meet UL94 V-0 flammability standards.

Q: What is the significance of the 5.08mm pitch in part 1759033?

A: The 5.08mm pitch represents a 0.08mm deviation from the original 5.00mm specification. This falls within standard mechanical tolerance for terminal block connectors and does not affect electrical performance or mating compatibility with standard 5.00mm pitch connectors. However, PCB layout spacing should be verified to ensure no mechanical interference.

Q: Are the Phoenix Contact substitutes electrically equivalent to the original part?

A: Both Phoenix Contact parts meet or exceed the electrical requirements. Under UL standards, they provide 300 V and 15 A ratings, compared to the original 20 A rating. The 5 A difference does not affect typical terminal block applications. Phoenix Contact parts additionally provide IEC ratings (400 V, 12 A), offering broader international compliance.

Q: Does the housing material change affect performance?

A: No. Both Polybutylene Terephthalate (PBT) and Polyamide (PA/Nylon) meet UL94 V-0 flammability requirements. Material selection does not impact electrical performance, voltage withstand, or current capacity within the specified operating parameters.

Q: What is the impact of different contact tail lengths?

A: Contact tail length affects solder joint depth on the PCB. The original part has 0.157" (4.00mm) tails, while Phoenix Contact substitutes have 0.138" (4.60mm) tails. This 0.019" difference requires verification that PCB solder pads are designed to accommodate the shorter tail length without compromising solder joint quality or mechanical strength.

Q: Are all three parts RoHS3 compliant?

A: Yes. The Würth Elektronik 691312710004 and both Phoenix Contact substitutes (1754478 and 1759033) are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.
