2RS1-11-G Equivalent & Substitute Parts

Part Overview

The 2RS1-11-G is an 11-position receptacle connector manufactured by Adam Tech, designed for board-to-board applications with 2.0mm pitch through-hole solder termination. This connector features gold-plated female socket contacts rated for 1A at 250VAC and operates across -40°C to 105°C. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The 831-47-011-10-001000 manufactured by Mill-Max Manufacturing Corp. qualifies as a functional equivalent based on the following critical parameters:

Matching Parameters:

• 11-position receptacle configuration
• 0.079" (2.00mm) mating pitch
• Board-to-board style
• Through-hole solder termination
• Push-pull fastening mechanism
• Gold contact finish on mating surface
• Female socket contact type
• Single row configuration

The substitute maintains mechanical and electrical compatibility within the connector interface, allowing direct replacement in applications where the main part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The 831-47-011-10-001000 provides mechanical and electrical interface compatibility with the obsolete 2RS1-11-G. The substitute demonstrates superior current rating (3A versus 1A) and extended operating temperature range (-55°C to 125°C versus -40°C to 105°C), offering enhanced performance margins for most applications.

Key consideration: The substitute part is RoHS non-compliant, whereas the original 2RS1-11-G meets ROHS3 compliance. Applications subject to RoHS regulatory requirements must evaluate this compliance difference before substitution. The substitute's voltage rating is not specified in available documentation, requiring verification against application requirements where the original 250VAC rating is critical.

Frequently Asked Questions (FAQ)

Q: Can the 831-47-011-10-001000 directly replace the 2RS1-11-G in existing designs?

A: Yes, for mechanical and electrical interface compatibility. Both connectors share identical 11-position, 2.0mm pitch receptacle configuration with through-hole solder termination and push-pull fastening. Physical board layout and mating connector compatibility remain unchanged.

Q: What are the key differences between these parts?

A: The substitute offers higher current capacity (3A versus 1A) and wider operating temperature range (-55°C to 125°C versus -40°C to 105°C). The substitute uses beryllium copper contacts versus phosphor bronze, and PCT/polyester insulation versus PBT. The substitute is RoHS non-compliant while the original meets ROHS3 standards.

Q: Does the higher current rating of the substitute affect compatibility?

A: No. Higher current rating indicates enhanced capability and does not compromise compatibility with applications designed for 1A operation. The substitute remains suitable for the original application's electrical requirements.

Q: Are there packaging differences between these parts?

A: The original 2RS1-11-G packaging is not specified. The substitute 831-47-011-10-001000 is supplied in bulk packaging.

Q: What compliance considerations apply to substitution?

A: The original part meets ROHS3 compliance; the substitute does not. Applications requiring RoHS compliance must retain the original specification or identify alternative compliant sources. Voltage rating verification is recommended for the substitute where 250VAC operation is specified.
