Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1775372001 is determined by the following critical parameters:

Primary Matching Criteria:

• 16 positions with 0.200" (5.08mm) pitch
• 90° right-angle orientation
• Male pins with 4-side shrouding
• Through-hole solder termination
• UL94 V-0 flammability rating
• 400V IEC voltage rating

Secondary Compatibility Factors:

• Current rating (IEC and UL)
• Contact tail length
• Insulation height
• Housing material composition
• Contact mating finish

The substitute parts listed below maintain the primary matching criteria. Variations in current ratings and contact tail length are noted, as these parameters affect mechanical fit and electrical performance in specific applications.

Parameter Comparison

Engineering Selection Recommendations

Weidmüller 1780570000 and 1837770000 are direct active-status replacements within the Omnimate SL series. Both maintain identical electrical specifications (27.5A IEC, 18.5A UL) and mechanical compatibility with the original 1775372001. The primary difference between these two Weidmüller substitutes is the feature set: 1780570000 includes mating flange and solder retention, while 1837770000 includes both mating and mounting flange. Both are RoHS compliant and carry MSL rating of 1 (Unlimited). The contact tail length of 0.126" (3.20mm) differs from the original 0.059" (1.50mm), requiring PCB layout verification.

Phoenix Contact 1776838 and 1809212 are cross-manufacturer alternatives with reduced current ratings (12A IEC, 15A UL). These parts maintain the 16-position, 5.08mm pitch, 90° right-angle configuration and UL94 V-0 rating. Part 1776838 uses 5.00mm pitch (0.197"), introducing a minor pitch deviation. Part 1809212 maintains exact 5.08mm pitch matching. Both Phoenix Contact options feature PBT housing material instead of LCP and include ROHS3 compliance. The contact tail length of 0.138" (4.60mm) requires PCB footprint assessment. These substitutes are suitable only for applications where the reduced current capacity is acceptable.

Product Status Consideration: All substitute parts carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete 1775372001.

Frequently Asked Questions (FAQ)

Q: Can 1780570000 or 1837770000 be used as direct replacements for 1775372001?

A: Yes, both Weidmüller parts maintain identical electrical ratings (27.5A IEC, 18.5A UL, 400V IEC, 300V UL) and core mechanical specifications (16 positions, 5.08mm pitch, 90° right angle, through-hole solder termination). The primary consideration is contact tail length: the substitutes measure 0.126" (3.20mm) versus the original 0.059" (1.50mm). PCB layout and solder pad depth must be verified for compatibility.

Q: What is the difference between 1780570000 and 1837770000?

A: Both parts are electrically and mechanically identical. The distinction lies in mounting features: 1780570000 includes mating flange and solder retention, while 1837770000 includes both mating and mounting flange. Selection depends on the mechanical mounting requirements of the application.

Q: Can Phoenix Contact parts 1776838 or 1809212 replace the Weidmüller 1775372001?

A: These Phoenix Contact alternatives are functionally compatible in terms of position count, pitch, orientation, and flammability rating. However, they carry reduced current ratings (12A IEC, 15A UL versus 27.5A IEC, 18.5A UL). Substitution is valid only if the application current requirements do not exceed 12A IEC or 15A UL. Part 1776838 uses 5.00mm pitch instead of 5.08mm, introducing a minor deviation.

Q: What is the significance of contact tail length differences?

A: Contact tail length affects solder joint formation and PCB pad design. The original 1775372001 has a 0.059" (1.50mm) tail, while substitutes range from 0.126" to 0.138". Longer tails provide greater solder joint strength but require deeper PCB pad holes. PCB design must accommodate the substitute part's tail length to ensure proper solder wetting and mechanical integrity.

Q: Are all substitute parts RoHS compliant?

A: Yes. Weidmüller substitutes 1780570000 and 1837770000 are RoHS compliant. Phoenix Contact parts 1776838 and 1809212 are ROHS3 compliant. The original 1775372001 does not specify RoHS status.

Q: What is the difference in housing material between Weidmüller and Phoenix Contact options?

A: Weidmüller parts use Liquid Crystal Polymer (LCP) with glass filling, while Phoenix Contact parts use Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption, while PBT provides cost efficiency. Material selection should align with application environmental conditions and thermal cycling requirements.

Q: Can pitch differences affect mechanical compatibility?

A: Yes. Part 1776838 uses 0.197" (5.00mm) pitch versus the standard 0.200" (5.08mm). This 0.03mm per position difference accumulates across 16 positions, resulting in approximately 0.48mm total dimensional variance. Mating connector compatibility must be verified before substitution.
