Engineering Selection Recommendations

The 831-47-017-10-001000 is an active product with current manufacturing availability, addressing the obsolescence status of the 2RS1-17-G. Both connectors maintain identical mating pitch, position count, and board-to-board interface geometry, ensuring mechanical compatibility.

The substitute part provides superior current rating (3A versus 1A) and extended operating temperature range (-55°C to 125°C versus -40°C to 105°C), offering performance headroom for applications within the original design envelope.

The 2RS1-17-G is ROHS3 compliant, while the 831-47-017-10-001000 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this compliance difference. Both parts maintain REACH unaffected status and EAR99 export classification.

Physical differences include contact post length (0.125" versus 0.094") and contact geometry (circular versus square), which may affect insertion force and mating characteristics. PCB layout and connector housing design should be evaluated for accommodation of these dimensional variations.

Frequently Asked Questions (FAQ)

Q: Can the 831-47-017-10-001000 directly replace the 2RS1-17-G in existing designs?

A: Mechanical mating compatibility is maintained through identical pitch (2.0mm) and position count (17). However, differences in contact post length, contact shape, and contact material require verification of insertion force, mating reliability, and electrical performance within the specific application circuit.

Q: What is the significance of the current rating difference (1A versus 3A)?

A: The 831-47-017-10-001000 supports higher current capacity. Applications operating at or near the 1A limit of the original part may benefit from this increased rating. Designs operating below 1A remain within the safe operating range of both parts.

Q: How do the operating temperature ranges compare?

A: The 831-47-017-10-001000 extends the lower temperature limit to -55°C and upper limit to 125°C, compared to -40°C to 105°C for the 2RS1-17-G. Applications within the original temperature range are compatible with both parts.

Q: What is the impact of RoHS compliance differences?

A: The 2RS1-17-G is ROHS3 compliant; the 831-47-017-10-001000 is RoHS non-compliant. Applications subject to RoHS directives or customer requirements must use the compliant part or obtain regulatory exemptions.

Q: Are there physical installation considerations?

A: The substitute part has a longer contact post (0.125" versus 0.094") and circular contact geometry versus square. PCB hole sizing, connector housing design, and insertion force characteristics should be evaluated for compatibility with existing mechanical assemblies.

Q: What packaging format is available for the substitute part?

A: The 831-47-017-10-001000 is supplied in bulk packaging, compared to the original part's unspecified packaging format.
