Engineering Selection Recommendations

Primary Substitute - Direct Replacement:

The part 2-1761603-5 (TE Connectivity) is the direct equivalent to 1761603-5. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The only difference is packaging format (Bulk versus original specification). This part is the preferred selection for direct substitution in new designs and procurement.

Secondary Substitutes - TE Connectivity Series:

The part 5103309-2 (TE Connectivity, AMP-Latch series) provides functional equivalence with active status and ROHS3 compliance. Contact material differs (Brass versus Phosphor Bronze), and insulation material is not specified. This part maintains identical pitch, position count, and operating temperature range.

Alternative Substitutes - HARTING SEK Series:

The HARTING SEK series parts (09185145322, 09185145324, 09185146322, 09185146324, 09185147322, 09185147324, 09195145324, 09195146324) provide functional equivalence with the following considerations:

All parts are active with ROHS3 compliance
Fastening mechanism differs (Latch Holder versus Push-Pull)
Operating temperature range extends to 125°C maximum (versus 105°C)
Contact material is Copper Alloy (versus Phosphor Bronze)
Insulation material is PBT Glass Filled or PCT Glass Filled (versus standard PBT)
Contact post length varies (0.114" to 0.177")

These parts are suitable for applications where the extended operating temperature range and alternative fastening mechanism are compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can 2-1761603-5 be used as a direct replacement for 1761603-5?

A: Yes. The 2-1761603-5 is functionally equivalent to 1761603-5 with identical electrical and mechanical specifications. The primary difference is product status (Active versus Obsolete) and ROHS3 compliance. Packaging format differs (Bulk), but connector specifications remain unchanged.

Q: What is the difference between Push-Pull and Latch Holder fastening types?

A: Push-Pull fastening uses a push-pull mechanism for mating and unmating. Latch Holder fastening uses a latch mechanism. Both are mechanical fastening methods for connector engagement. Selection depends on application requirements for mating force and engagement method.

Q: Are HARTING SEK series parts compatible with TE Connectivity AMP-Latch designs?

A: HARTING SEK series parts maintain identical pitch (2.54mm), position count (14), row configuration (2 rows), and shrouding specifications. However, fastening type differs (Latch Holder versus Push-Pull). Mechanical compatibility with mating connectors must be verified based on specific application requirements.

Q: What is the significance of the extended operating temperature range in HARTING parts?

A: HARTING SEK series parts operate from -55°C to 125°C, compared to -65°C to 105°C for the original part. The extended upper temperature limit (125°C versus 105°C) provides additional thermal margin for high-temperature applications. The lower temperature limit is less stringent (-55°C versus -65°C).

Q: How do contact material differences affect connector performance?

A: The original 1761603-5 uses Phosphor Bronze contacts. Substitute parts use Brass or Copper Alloy contacts. All materials are suitable for the specified current rating (1A per contact) and voltage rating (250VAC). Material selection affects mechanical properties and corrosion resistance. Contact finish (Gold plating) provides the primary corrosion protection in all variants.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in Bulk, Tube, and Tray packaging formats. Packaging selection does not affect connector electrical or mechanical specifications and is determined by procurement and inventory management requirements.

Q: Is RoHS compliance required for substitute part selection?

A: The original 1761603-5 has RoHS status listed as "Not applicable." All active substitute parts listed are ROHS3 Compliant. For applications subject to RoHS regulations, ROHS3 Compliant parts are required. For applications without RoHS requirements, compliance status does not affect connector functionality.

Q: Can insulation material differences impact connector reliability?

A: The original part uses standard PBT insulation. Substitute parts use PBT Glass Filled or PCT Glass Filled insulation. Glass-filled variants provide enhanced mechanical strength and thermal stability. All materials meet UL94 V-0 flammability requirements. Material selection does not affect electrical performance for the specified voltage and current ratings.
