Engineering Selection Recommendations

The TE Connectivity AMP Connectors 3-1761605-5 is a direct functional substitute for the obsolete HARTING 09185505321. Both components maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications.

The substitute part offers active product status, ensuring long-term availability and supply chain continuity. Contact material composition differs (phosphor bronze versus copper alloy), but both materials provide equivalent electrical and mechanical performance within the specified operating parameters.

Operating temperature ranges show partial overlap. The HARTING part supports -55°C to 125°C, while the TE Connectivity part supports -65°C to 105°C. Design applications operating within the -55°C to 105°C window experience full compatibility. Applications requiring operation above 105°C or below -65°C require thermal performance verification against specific design requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-1761605-5 directly replace the HARTING 09185505321 in existing designs?

A: Yes. Both connectors share identical pitch, position count, row configuration, mounting orientation, and shrouding design. Mechanical and electrical interfaces are equivalent. The substitute part is active and readily available.

Q: What is the difference between the fastening types listed for these parts?

A: The HARTING part uses a latch holder fastening mechanism, while the TE Connectivity part uses push-pull fastening. Both mechanisms provide secure mating and are functionally equivalent for board-to-cable/wire applications.

Q: Are there thermal operating range limitations when substituting?

A: The TE Connectivity part operates from -65°C to 105°C, compared to the HARTING part's -55°C to 125°C range. Applications operating within -55°C to 105°C experience full compatibility. Applications requiring operation above 105°C or below -65°C require thermal performance assessment.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the HARTING 09185505321 and TE Connectivity 3-1761605-5 are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the difference in contact material composition?

A: The HARTING part uses copper alloy contacts, while the TE Connectivity part uses phosphor bronze contacts. Both materials provide equivalent electrical conductivity and mechanical durability for this connector class.

Q: Is the insulation material composition identical?

A: Both parts use polybutylene terephthalate (PBT) insulation. The HARTING part specifies glass-filled PBT, while the TE Connectivity part specifies PBT without explicit glass-fill notation. Both materials meet UL94 V-0 requirements.
