Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 2-1761605-9

The 2-1761605-9 is the direct functional equivalent of the obsolete 1761605-9. This part maintains identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status transition from obsolete to active, coupled with RoHS compliance certification. The packaging format change from unspecified to bulk does not affect electrical or mechanical compatibility. The insulation color variation (blue versus black) is a cosmetic difference without functional impact. This part is the preferred selection for direct replacement applications requiring minimal design modification.

Secondary Substitute: 5103311-6

The 5103311-6 provides functional equivalence with allowable dimensional variations in contact post length (0.135" versus 0.102") and insulation height (0.360" versus 0.350"). These variations remain within acceptable tolerance ranges for through-hole solder termination applications. The contact material composition differs (brass versus phosphor bronze), and the contact finish mating surface offers gold-palladium as an alternative to pure gold. Enhanced compliance certifications include ROHS3 and REACH Unaffected status. This part is suitable for applications where the dimensional variations do not conflict with PCB layout constraints or mating connector specifications. Tube packaging format is appropriate for production environments requiring controlled component dispensing.

Compliance Considerations:

Both substitute parts offer improved regulatory compliance compared to the obsolete original. The 2-1761605-9 provides RoHS compliance, while the 5103311-6 provides ROHS3 compliance with REACH Unaffected status. Selection between these alternatives should account for specific regulatory requirements applicable to the end application and geographic market.

Frequently Asked Questions (FAQ)

Q: Can the 2-1761605-9 be used as a direct replacement for the 1761605-9 without PCB redesign?

A: Yes. The 2-1761605-9 maintains identical pitch spacing (0.100"), row configuration (2 rows), position count (26), mounting type (through-hole right-angle), and all electrical ratings. No PCB layout modifications are required for direct substitution.

Q: What is the significance of the insulation color difference between 1761605-9 (black) and 2-1761605-9 (blue)?

A: Insulation color is a visual identification feature without electrical or mechanical function. The color variation does not affect connector performance, compatibility, or electrical characteristics. Selection between black and blue insulation is based on assembly documentation or internal color-coding standards.

Q: Are there dimensional differences between the 2-1761605-9 and 5103311-6 that affect PCB compatibility?

A: Yes. The 5103311-6 has a longer contact post (0.135" versus 0.102") and slightly greater insulation height (0.360" versus 0.350"). These variations may affect PCB hole depth requirements and solder joint geometry. Verify PCB design specifications before selecting the 5103311-6 for applications previously designed for the 1761605-9 or 2-1761605-9.

Q: What is the difference between the contact materials used in these parts?

A: The 1761605-9 and 2-1761605-9 use phosphor bronze contacts, while the 5103311-6 uses brass contacts. Both materials provide adequate electrical conductivity and mechanical durability for the specified 1A per contact current rating. Material selection does not affect electrical compatibility in standard applications.

Q: Does the contact finish variation (gold versus gold-palladium) affect mating performance?

A: No. Both gold and gold-palladium finishes provide equivalent contact resistance and corrosion resistance for the specified 250VAC, 1A per contact application. The finish variation does not affect electrical performance or connector reliability.

Q: What packaging format should be selected for production assembly?

A: The 2-1761605-9 is supplied in bulk packaging, suitable for high-volume automated assembly operations. The 5103311-6 is supplied in tube packaging, appropriate for controlled dispensing in manual or semi-automated assembly environments. Packaging selection should align with assembly process requirements and component handling procedures.

Q: Are both substitute parts RoHS compliant?

A: The 2-1761605-9 is RoHS compliant. The 5103311-6 is ROHS3 compliant, representing an enhanced compliance standard. Both parts satisfy RoHS requirements for applications subject to this regulation. The original 1761605-9 RoHS status is not specified.

Q: Can the 5103311-6 be used in applications designed for the 1761605-9?

A: Functional compatibility is confirmed across all critical electrical and mechanical parameters. However, the dimensional variations in contact post length and insulation height require verification against specific PCB design specifications, mating connector geometry, and solder joint requirements. Dimensional compatibility assessment is necessary before design implementation.

Q: What is the current inventory status for each part?

A: The 1761605-9 (obsolete) has 699 units in stock. The 2-1761605-9 (active) has 2027 units in stock. The 5103311-6 (active) has 1346 units in stock. Inventory levels support both immediate replacement requirements and ongoing production needs.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All three parts maintain identical electrical specifications: 1A per contact current rating, 250VAC voltage rating (specified for 1761605-9 and 2-1761605-9), -65°C to 105°C operating temperature range, and UL94 V-0 flammability rating. Electrical performance is equivalent across all substitution options.
