Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1844580000 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 17 positions at 0.200" (5.08mm) spacing
• Electrical Ratings: 20 A current and 300 V voltage capacity
• Wire Compatibility: 12-26 AWG wire gauge acceptance
• Termination Method: Screw-clamping with tension sleeve
• Mounting Configuration: Through-hole, horizontal orientation with board
• Compliance: RoHS compliance and EAR99 classification

The substitute part 1977610000 meets all these criteria, with the distinction that it represents an active product from the Omnimate LL2N series, offering extended operating temperature range and improved housing material specifications.

Parameter Comparison

Engineering Selection Recommendations

The 1977610000 is the direct functional equivalent for applications currently using the 1844580000. Both components share identical electrical ratings, termination architecture, and PCB footprint compatibility. The primary distinction is product lifecycle status: the 1844580000 is obsolete, while the 1977610000 is active and supported by the manufacturer.

Selection of the 1977610000 is appropriate for new designs and production continuity. The extended operating temperature range (-50°C ~ 120°C versus -50°C ~ 100°C) provides additional thermal margin without introducing compatibility concerns. Both parts maintain RoHS compliance and EAR99 classification, ensuring regulatory consistency across supply chain transitions.

Frequently Asked Questions (FAQ)

Q: Can the 1977610000 be used as a direct replacement for the 1844580000 in existing PCB designs?

A: Yes. Both components feature identical 17-position configuration at 0.200" (5.08mm) pitch with through-hole mounting. Electrical ratings (20 A, 300 V), wire gauge acceptance (12-26 AWG), and screw-termination specifications are equivalent. PCB footprint compatibility is maintained.

Q: What is the difference between the Omnimate LP and Omnimate LL2N series?

A: The 1844580000 belongs to the Omnimate LP series (obsolete), while the 1977610000 is from the Omnimate LL2N series (active). The LL2N series represents the current product line with improved housing material (Thermoplastic, Wemid) and extended temperature range. Functional and electrical characteristics remain equivalent.
