Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1761142001 is determined by strict equivalence across the following critical parameters:

• Electrical Ratings: Current (15A IEC / 10A UL) and voltage (320V IEC / 300V UL) must match exactly
• Physical Configuration: 20 positions, 0.138" (4.60mm) pitch, vertical orientation, male pins with 4-side shrouding
• Termination Method: Solder termination for through-hole mounting
• Material & Compliance: UL94 V-0 flammability rating, RoHS compliance, and operating temperature range (-50°C to 100°C)
• Contact & Housing Materials: Copper alloy contacts and liquid crystal polymer (LCP) glass-filled housing

The substitute part 1842950000 meets all these criteria and represents the active production equivalent within the Omnimate SL series.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1842950000 is the direct active equivalent for the obsolete 1761142001. Both components are manufactured by Weidmüller within the Omnimate SL series and share identical electrical ratings, physical dimensions, and compliance certifications (UL94 V-0, RoHS, REACH Unaffected).

The primary difference between these parts is the contact tail length: the 1761142001 features a 0.059" (1.50mm) tail, while the 1842950000 provides a 0.126" (3.20mm) tail. This difference affects PCB pad design and solder joint geometry. For new designs or board revisions, the 1842950000 is the recommended selection due to its active product status and improved availability. For legacy board compatibility where the shorter tail length is critical, the contact tail length difference must be evaluated against PCB layout constraints.

Both parts maintain identical electrical performance, temperature range, and regulatory compliance, ensuring functional interchangeability within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1842950000 directly replace the 1761142001 on existing PCBs?

A: Electrical and mechanical compatibility is confirmed across all critical parameters. However, the contact tail length differs (0.059" vs. 0.126"), which may affect solder joint formation and PCB pad design. PCB layout review is necessary to confirm physical compatibility with existing through-hole pad patterns.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1761142001 is no longer manufactured. The 1842950000 is the current production equivalent within the Omnimate SL series, ensuring long-term availability and supply chain continuity for new applications and production runs.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components are rated at 15A (IEC) / 10A (UL) and 320V (IEC) / 300V (UL), with identical operating temperature ranges (-50°C to 100°C) and compliance certifications.

Q: What is the difference in contact tail length, and does it affect functionality?

A: The 1761142001 has a 0.059" (1.50mm) contact tail, while the 1842950000 has a 0.126" (3.20mm) tail. This affects solder joint depth and PCB pad design but does not impact electrical performance. Pad geometry must be verified for compatibility with the longer tail length.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 1761142001 and 1842950000 are RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What packaging options are available?

A: The 1761142001 was supplied with standard packaging (status: obsolete). The 1842950000 is available in Bulk packaging as the active production equivalent.
