A-2004-3-4-R Modular Connector Jack Equivalent & Substitute Parts

Part Overview

The A-2004-3-4-R is a modular connector jack manufactured by Assmann WSW Components, designed for 4-position 4-contact (4p4c) applications including RJ9, RJ10, and RJ22 configurations. This connector features a 90° right-angle orientation with through-hole solder termination and unshielded design. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this connector type is required.

Substitute Part Grouping Explanation

Substitute parts for the A-2004-3-4-R are identified based on strict electrical and mechanical parameter matching. The critical parameters that determine substitution eligibility are:

Connector type (Jack)
Contact configuration (4p4c / RJ9, RJ10, RJ22)
Mounting method (Through Hole)
Orientation (90° Angle Right)
Termination method (Solder)
Shielding type (Unshielded)
Tab direction (Down)
Contact finish (Gold)
Moisture sensitivity level (MSL 1)

Two substitute parts meet these core requirements: A-20040 (direct manufacturer equivalent from Assmann WSW Components) and 68897-001LF (cross-manufacturer equivalent from Amphenol ICC/FCI). Both maintain functional and mechanical compatibility with the original A-2004-3-4-R specification.

Engineering Selection Recommendations

A-20040 (Assmann WSW Components): This part is the direct equivalent from the original manufacturer. It maintains identical electrical and mechanical specifications to the A-2004-3-4-R, including contact material, finish thickness, housing material, and operating temperature range. The part is currently in active production status with higher inventory availability (1242 pcs). It carries RoHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part. This substitute is the primary choice for direct replacement applications.

68897-001LF (Amphenol ICC/FCI): This cross-manufacturer substitute maintains functional compatibility across all critical parameters: connector type, contact configuration, mounting method, orientation, termination, shielding, and tab direction. The part is actively produced with substantial inventory (4711 pcs). Differences include contact material (copper alloy vs. phosphor bronze), contact finish thickness (5.00µin vs. 6.00µin), housing material (polyamide/nylon vs. polyester/glass-filled), and operating temperature upper limit (70°C vs. 85°C). The part carries RoHS compliance and REACH affected status. This substitute is suitable for applications where the operating temperature does not exceed 70°C and cross-manufacturer sourcing is acceptable.

Frequently Asked Questions (FAQ)

Q: Can A-20040 be used as a direct replacement for A-2004-3-4-R?

A: Yes. A-20040 is the direct manufacturer equivalent with identical specifications across all critical parameters including connector type, contact configuration, mounting method, orientation, termination, shielding, contact finish, and operating temperature range. The only difference is product status (active vs. obsolete) and packaging format.

Q: What are the key differences between A-20040 and 68897-001LF?

A: Both parts share identical electrical and mechanical core specifications for 4p4c jack connectors with 90° right-angle orientation and solder termination. Differences include: contact material (phosphor bronze vs. copper alloy), contact finish thickness (6.00µin vs. 5.00µin), housing material (polyester/glass-filled vs. polyamide/nylon), maximum operating temperature (85°C vs. 70°C), and regulatory status (REACH unaffected vs. REACH affected).

Q: Is 68897-001LF compatible with applications requiring 85°C operation?

A: No. The 68897-001LF has a maximum operating temperature of 70°C. For applications requiring operation up to 85°C, use A-20040 or the original A-2004-3-4-R specification.

Q: What packaging formats are available for these substitutes?

A: A-2004-3-4-R is supplied in standard packaging (format not specified). A-20040 is supplied in Tray packaging. 68897-001LF is supplied in Tube packaging. Packaging format should be confirmed with procurement requirements.

Q: Are both substitutes RoHS compliant?

A: A-20040 is RoHS3 compliant. 68897-001LF is RoHS compliant. Both meet RoHS requirements, though under different compliance standards.

Q: Which substitute has better inventory availability?

A: 68897-001LF has the highest inventory (4711 pcs), followed by A-20040 (1242 pcs). Inventory levels should be confirmed at time of procurement.
