HARTING 09185507321 Equivalent & Substitute Parts

Part Overview

The HARTING 09185507321 is a rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This 50-position connector operates at 0.100" (2.54mm) pitch with shrouded 4-wall construction and solder termination. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement continuity.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors part 3-1761605-5 is the direct equivalent for the obsolete HARTING 09185507321. Both components share identical mechanical and electrical interface specifications across all critical parameters: 50-position, 2-row configuration at 0.100" pitch, through-hole right-angle mounting, shrouded 4-wall design, and solder termination with gold-plated mating contacts.

Key selection factors:

Product Status: The TE Connectivity part maintains active production status, ensuring long-term availability and supply chain continuity.
Compliance Alignment: Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements.
Electrical Specifications: The TE Connectivity substitute provides defined current (1A per contact) and voltage (250VAC) ratings, whereas the original part does not specify these values.
Operating Temperature: The TE Connectivity part operates across -65°C to 105°C, which overlaps the original specification of -55°C to 125°C. Applications requiring the full original temperature range should be evaluated against the substitute's narrower specification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-1761605-5 directly replace the HARTING 09185507321 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (50), row configuration (2 rows), mounting type (through-hole right-angle), and shrouding design (4-wall). The mechanical and electrical interfaces are equivalent. However, verify that your application's operating temperature requirements fall within the TE Connectivity part's range of -65°C to 105°C.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer identity, fastening type (HARTING uses latch holder; TE Connectivity uses push-pull), contact post length (HARTING 0.177", TE Connectivity 0.102"), insulation height (HARTING 0.366", TE Connectivity 0.350"), and contact material (HARTING uses copper alloy; TE Connectivity uses phosphor bronze). The TE Connectivity part also provides explicit current and voltage ratings.

Q: Are there packaging considerations when switching to the substitute part?

A: The HARTING part packaging is not specified in the available data. The TE Connectivity 3-1761605-5 is supplied in bulk packaging. Confirm bulk packaging compatibility with your procurement and assembly processes.

Q: Does the narrower operating temperature range of the TE Connectivity part affect compatibility?

A: The TE Connectivity part operates from -65°C to 105°C, compared to the HARTING part's -55°C to 125°C range. If your application requires operation below -55°C or above 105°C, the substitute may not be suitable. For applications within the overlapping range (-55°C to 105°C), the substitute is fully compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both the HARTING 09185507321 and TE Connectivity 3-1761605-5 are ROHS3 compliant and carry UL94 V-0 flammability ratings.
