Key Parameters

Substitute Part Grouping Explanation

The JT7-1115NL from Pulse Electronics qualifies as a direct substitute for the ARJ-128 based on the following critical parameters:

Functional equivalence is established through matching connector type (RJ45), port configuration (1 port), application support (10G Base-T with AutoMDIX), mounting method (Through Hole), physical orientation (90° Angle Right), and termination approach (Solder). Both connectors provide shielded designs with EMI finger protection and board guide features, ensuring mechanical and electrical compatibility in PCB layouts.

Environmental and regulatory alignment is confirmed through identical operating temperature range (0°C ~ 70°C), matching moisture sensitivity level (MSL 1 - Unlimited), and equivalent RoHS compliance status. Both parts carry ECCN EAR99 classification.

Parameter Comparison

Engineering Selection Recommendations

The JT7-1115NL is the qualified substitute for the ARJ-128. The ARJ-128 is classified as obsolete, while the JT7-1115NL maintains active product status with current manufacturing support. Both connectors meet RoHS compliance requirements and carry identical ECCN classification (EAR99), ensuring regulatory alignment for procurement and deployment.

The JT7-1115NL is available in active inventory (950 Pcs) with established supply chain support, whereas the ARJ-128 is no longer in active production. For new designs or component replenishment, the JT7-1115NL provides continuity of electrical and mechanical function with the advantage of ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Can the JT7-1115NL directly replace the ARJ-128 in existing PCB designs?

A: Yes. Both connectors share identical connector type (RJ45), port count (1), mounting method (Through Hole), orientation (90° Angle Right), and solder termination. The height above board difference (0.531" vs 0.525") is within typical PCB layout tolerances for this connector category.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant and carry ECCN EAR99 classification. The ARJ-128 is ROHS3 compliant while the JT7-1115NL is RoHS compliant. Both meet MSL 1 (Unlimited) moisture sensitivity requirements.

Q: What is the primary reason for substitution?

A: The ARJ-128 is obsolete and no longer in active production. The JT7-1115NL is an active product with current manufacturing support and established inventory availability.

Q: Are the electrical specifications identical?

A: Both connectors support 10G Base-T applications with AutoMDIX functionality, identical operating temperature range (0°C ~ 70°C), and matching LED indicator colors (Green, Yellow - Green). Both feature shielded designs with EMI finger protection and board guide features.

Q: What packaging format is the JT7-1115NL supplied in?

A: The JT7-1115NL is supplied in Tray packaging, whereas the ARJ-128 packaging specification was not provided in the original documentation.
