Molex 0432028113 Equivalent & Substitute Parts

Part Overview

The Molex 0432028113 is a jack modular connector (8p8c/RJ45) with 90° right-angle orientation, unshielded design, and through-hole solder termination. Rated for Cat4 performance, this connector features board lock and keyed design with phosphor bronze gold-plated contacts. The part is currently active in production with 831 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward enhanced shielding or higher category ratings, or when alternative sourcing improves supply chain resilience. The following equivalent and substitute parts maintain core functional compatibility while offering variations in shielding, category rating, and mounting specifications.

Engineering Selection Recommendations

Direct Unshielded Equivalents (Preferred for Pin-Compatible Replacement):

1116504-2 (TE Connectivity) and FRJAE-408 (Amphenol ICC) are the primary unshielded alternatives. Both maintain through-hole mounting, solder termination, and phosphor bronze gold-plated contacts. The 1116504-2 offers Cat5 rating (superior to Cat4) with identical contact finish thickness. The FRJAE-408 extends operating temperature to -55°C. Both are active products with robust inventory levels.

Shielded Alternatives (Enhanced EMI Protection):

1116503-2, FRJAE-418, FRJAE-438, and FRJAE-468 provide shielded variants. These are suitable when EMI rejection becomes a design requirement. The 1116503-2 combines shielding with Cat5 rating and board edge/through-hole flexibility. Amphenol FRJAE shielded variants (418, 438, 468) offer extended temperature range (-55°C to 85°C) and high inventory availability.

Avoid:

E5388-000012-L (Pulse Electronics) carries obsolete product status and lower Cat3 rating. A-20042/LP (Assmann WSW) lacks category specification and has reduced contact finish thickness (6.00µin vs. 50.0µin standard).

Compliance Considerations:

All recommended substitutes maintain RoHS compliance. The primary part and most substitutes are ROHS3 compliant. MSL 1 rating is consistent across all parts, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I substitute an unshielded connector with a shielded variant?

A: Yes. Shielded connectors are functionally compatible with unshielded designs. The shielding provides additional EMI rejection without affecting pin compatibility or electrical performance. Mechanical fit must be verified for board layout.

Q: What is the difference between Cat4 and Cat5 ratings?

A: Cat5 connectors support higher bandwidth and are backward compatible with Cat4 applications. Substituting Cat4 with Cat5 introduces no functional risk and improves performance headroom.

Q: Are Amphenol FRJAE-408, FRJAE-418, FRJAE-438, and FRJAE-468 interchangeable?

A: FRJAE-408 is unshielded; FRJAE-418, FRJAE-438, and FRJAE-468 are shielded variants. Within the shielded group, all three are mechanically and electrically compatible. Selection depends on EMI filtering requirements and board space constraints.

Q: Does the extended temperature range (-55°C to 85°C) on Amphenol parts affect compatibility?

A: No. Extended temperature range is a superset of the primary part's range (-40°C to 85°C). Amphenol parts are fully compatible and suitable for applications requiring lower temperature operation.

Q: Why does A-20042/LP have lower contact finish thickness?

A: Contact finish thickness variation (6.00µin vs. 50.0µin) affects contact durability and mating cycle life. The primary part and recommended substitutes maintain 50.0µin thickness for consistent performance. A-20042/LP is not recommended as a primary substitute.

Q: Is the TE Connectivity 1116503-2 suitable for my unshielded design?

A: The 1116503-2 is shielded and includes an EMI finger. While mechanically compatible, it introduces shielding not present in the original design. Use only if EMI performance becomes a requirement or if board layout permits the additional shielding structure.

Q: What is the inventory advantage of selecting FRJAE-468 over other Amphenol variants?

A: FRJAE-468 has the highest inventory level (5233 units) among Amphenol shielded options. This provides supply chain advantage for high-volume production. Electrical and mechanical specifications are equivalent to FRJAE-418 and FRJAE-488.
