2RS1-19-G Equivalent & Substitute Parts

Part Overview

The 2RS1-19-G is a 19-position receptacle connector manufactured by Adam Tech, designed for board-to-board applications with 0.079" (2.00mm) pitch spacing. This connector features through-hole solder termination, gold-plated mating contacts, and operates across -40°C to 105°C. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 2RS1-19-G is determined by the following critical parameters:

• Connector Type & Contact Configuration: Must be receptacle with female socket contacts
• Position Count & Pitch: Must maintain 19 positions at 0.079" (2.00mm) mating pitch
• Mounting & Termination: Must support through-hole solder termination
• Electrical Interface: Must accommodate the same mating interface (board-to-board, push-pull fastening)
• Contact Finish: Gold-plated mating surface required for signal integrity

The substitute part 831-47-019-10-001000 (Mill-Max Manufacturing Corp.) satisfies these core substitution criteria. Both connectors share identical position count, pitch spacing, mounting method, and fastening mechanism, enabling direct functional replacement in applications where the 2RS1-19-G is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The 831-47-019-10-001000 serves as a functional substitute for the obsolete 2RS1-19-G based on matching mechanical and electrical interface specifications. Both connectors maintain identical position count, pitch, mounting configuration, and fastening mechanism.

The substitute part offers an extended operating temperature range (-55°C to 125°C versus -40°C to 105°C) and higher current rating (3A versus 1A), providing enhanced performance margins in thermal and power delivery scenarios.

The primary consideration is RoHS compliance status: the 2RS1-19-G is ROHS3 compliant, while the 831-47-019-10-001000 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this difference in material composition and environmental restrictions.

Frequently Asked Questions (FAQ)

Q: Can the 831-47-019-10-001000 directly replace the 2RS1-19-G in existing designs?

A: Yes, from a mechanical and electrical interface perspective. Both connectors share identical position count (19), mating pitch (0.079"), mounting type (through-hole), termination method (solder), and fastening mechanism (push-pull). The substitute will mate with the same complementary connector.

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (831-47-019-10-001000 extends to -55°C and 125°C), current rating (3A versus 1A), contact material composition (beryllium copper versus phosphor bronze), and RoHS compliance status (non-compliant versus compliant).

Q: Does RoHS non-compliance of the substitute part affect compatibility?

A: RoHS compliance affects material composition and regulatory eligibility, not mechanical or electrical compatibility. Applications requiring RoHS-compliant components must source alternatives meeting this certification.

Q: Are there packaging differences between these parts?

A: The 2RS1-19-G packaging is not specified in available data. The 831-47-019-10-001000 is supplied in bulk packaging.

Q: What is the contact finish difference between the two parts?

A: Both parts feature gold flash plating on mating contacts. The post contact finish differs: the 2RS1-19-G uses gold flash, while the 831-47-019-10-001000 uses tin with specified thickness (200.0µin / 5.08µm).
