Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1776242001 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (27.5A IEC), voltage rating (400V IEC), and contact material (Copper Alloy)
• Mechanical Configuration: 13 positions, 0.200" (5.08mm) pitch, vertical orientation, male pins with 4-side shrouding
• Mounting and Termination: Through-hole solder termination
• Environmental and Compliance: Operating temperature range (-50°C ~ 100°C), UL94 V-0 flammability rating, RoHS compliance
• Housing Material: Liquid Crystal Polymer (LCP), Glass Filled

The substitute part 1838320000 maintains full equivalence across all critical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The 1838320000 is a direct functional equivalent to the 1776242001 across all critical electrical, mechanical, and environmental parameters. The primary distinction is product status: the 1776242001 is obsolete, while the 1838320000 maintains active status with significantly higher inventory availability (1038 pcs vs. 631 pcs).

Both parts carry identical compliance certifications: RoHS compliance, UL94 V-0 flammability rating, REACH unaffected status, and EAR99 export classification. Both are rated for the same electrical performance (27.5A IEC, 400V IEC) and operate across the identical temperature range (-50°C ~ 100°C).

The contact tail length differs between the two parts (0.059" vs. 0.126"), which reflects manufacturing variations within the Omnimate SL series but does not affect functional compatibility in standard through-hole PCB applications.

For new designs or component replenishment, the 1838320000 is the recommended selection due to active product status and superior supply availability.

Frequently Asked Questions (FAQ)

Q: Can the 1838320000 directly replace the 1776242001 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 13 positions, 0.200" (5.08mm) pitch, vertical orientation, male pins with 4-side shrouding, 27.5A (IEC) current rating, and 400V (IEC) voltage rating. Both are rated for -50°C to 100°C operation and carry UL94 V-0 flammability certification.

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

A: The 1776242001 has a contact tail length of 0.059" (1.50mm), while the 1838320000 has 0.126" (3.20mm). This variation reflects manufacturing differences within the Omnimate SL series. For standard through-hole PCB applications with typical pad depths, both configurations are compatible. PCB design review is necessary only if specific solder joint depth requirements exist.

Q: Are there packaging differences between these parts?

A: The 1776242001 is listed with unspecified packaging, while the 1838320000 is supplied in bulk packaging. Both parts carry identical MSL rating (1 - Unlimited), indicating no moisture sensitivity concerns for either packaging configuration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1776242001 and 1838320000 are RoHS compliant, carry UL94 V-0 flammability rating, are REACH unaffected, and share the same ECCN (EAR99) and HTSUS code (8536.69.4040).

Q: Why is the 1776242001 marked as obsolete?

A: The 1776242001 has reached end-of-life status within Weidmüller's product portfolio. The 1838320000 represents the active equivalent within the Omnimate SL series, ensuring continued availability and supply chain support.
