MODM-D-02-8P8C-U-S4-G-G Equivalent & Substitute Parts

Part Overview

The MODM-D-02-8P8C-U-S4-G-G is a modular jack connector manufactured by Samtec Inc., designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and shielding. This connector features through-hole solder termination, board lock functionality, and EMI finger shielding rated for Cat3 performance. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the MODM-D-02-8P8C-U-S4-G-G is determined by strict alignment with the following core parameters:

Connector Type: Jack
Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
Number of Ports: 2
Number of Rows: 2
Mounting Type: Through Hole
Orientation: 90° Angle (Right)
Termination: Solder
Shielding: Shielded, EMI Finger
Contact Material: Phosphor Bronze
Contact Finish: Gold, 50.0µin (1.27µm)
Tab Direction: Up and Down
Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts (RJSAE-5381-02, RJSAE-5385-02, RJSAE-538A-02) from Amphenol ICC (Commercial Products) meet these core electrical and mechanical parameters. Variations in housing material (Thermoplastic vs. PBT Glass Filled), operating temperature range, LED color options, and product status do not affect functional substitution capability for this connector category.

Engineering Selection Recommendations

All three Amphenol ICC substitute parts are active products with current manufacturing status, providing supply continuity for applications currently using the obsolete MODM-D-02-8P8C-U-S4-G-G. All substitutes maintain RoHS compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Selection between RJSAE-5381-02, RJSAE-5385-02, and RJSAE-538A-02 is determined by LED color requirements for your specific application. RJSAE-5381-02 provides Yellow-Green LED indication, RJSAE-5385-02 provides Green-Green LED indication matching the original part, and RJSAE-538A-02 provides Green/Yellow-Green/Yellow LED options. All three connectors are electrically and mechanically equivalent for 8p8c RJ45 Ethernet applications.

Frequently Asked Questions (FAQ)

Q: Are the Amphenol RJSAE-538 series connectors electrically equivalent to the Samtec MODM-D-02-8P8C-U-S4-G-G?

A: Yes. All three substitute parts maintain identical contact material (Phosphor Bronze), contact finish (Gold, 50.0µin), connector configuration (8p8c, 2 ports, 2 rows), shielding (EMI Finger), and termination method (Solder). Electrical performance for RJ45 Ethernet applications is equivalent.

Q: What is the difference between the three Amphenol substitute options?

A: The primary difference is LED color indication. RJSAE-5381-02 features Yellow-Green LEDs, RJSAE-5385-02 features Green-Green LEDs (matching the original), and RJSAE-538A-02 offers Green/Yellow LED combinations. All other electrical and mechanical specifications are identical.

Q: Does the housing material difference affect compatibility?

A: The original part uses PBT Glass Filled housing while the substitutes use Thermoplastic housing. Both materials are suitable for through-hole solder termination and provide adequate mechanical support for 8p8c modular connectors. Material selection does not affect electrical performance or PCB mounting compatibility.

Q: Are there temperature range considerations for substitution?

A: The original part operates from -25°C to 90°C, while all substitutes operate from -55°C to 85°C. The substitute range is narrower at the upper limit (85°C vs. 90°C) but extends lower. For applications within -25°C to 85°C, all parts are functionally equivalent. Applications requiring operation above 85°C should retain the original specification.

Q: Are all substitute parts currently in stock?

A: Yes. RJSAE-5381-02 has 2515 units, RJSAE-5385-02 has 1188 units, and RJSAE-538A-02 has 1700 units available as new original stock.
