Terminal Block Connector 305130 Equivalent & Substitute Parts

Part Overview

The American Electrical Inc. 305130 is a 2-position feed-through terminal block connector rated for 10-26 AWG wire gauges. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The PEK series connector features screw termination with beige polyamide insulation and meets IEC 750V/32A and UL 600V/34A electrical specifications. Substitute parts must maintain compatibility across electrical ratings, wire gauge capacity, termination method, and physical form factor to ensure reliable circuit continuity in applications requiring feed-through terminal block connectivity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for terminal block connector 305130 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 2
• Type: Feed Through
• Termination style: Screw
• Wire gauge range: 10-26 AWG (0.5-6 mm²)
• Current rating (IEC): 32 A minimum
• Voltage rating (IEC): 750 V minimum
• Current rating (UL): 30 A minimum
• Voltage rating (UL): 600 V minimum
• Color: Beige
• Flammability rating: UL94 V-2 or equivalent
• RoHS compliance: ROHS3 Compliant

Both substitute parts 304139 and 304219 meet these criteria. Both are manufactured by American Electrical Inc., feature active product status, and maintain electrical and mechanical compatibility with the obsolete 305130 connector. The primary distinction between substitutes lies in terminal width (6.0 mm versus 6.5 mm on the original) and insulation material composition in part 304219.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 304139 and 304219 provide functional equivalence to the obsolete 305130 connector. Selection between substitutes is based on the following engineering considerations:

Part 304139 (AVK Series): This substitute maintains full electrical specification alignment with the original 305130, including identical insulation material composition (Polyamide PA66/Nylon 6/6) and confirmed UL94 V-2 flammability rating. The 0.5 mm reduction in terminal width (6.0 mm versus 6.5 mm) represents a minor mechanical variation that does not affect electrical performance or wire gauge compatibility. This part carries active product status with 992 units in current inventory.

Part 304219 (AVK Series): This substitute meets all mandatory electrical and dimensional requirements with identical wire gauge capacity and current/voltage ratings. The insulation material is specified as thermoplastic without explicit flammability rating documentation. This represents a material composition change from the original polyamide specification. This part carries active product status with 1107 units in current inventory.

For applications where original material specifications and flammability ratings must be preserved, part 304139 is the preferred substitute. For applications where thermoplastic insulation is acceptable, part 304219 provides an alternative with higher current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 304139 or 304219 directly replace 305130 in existing assemblies?

A: Both parts maintain electrical compatibility across IEC and UL ratings, wire gauge capacity, and screw termination method. The 0.5 mm terminal width reduction in both substitutes does not affect wire insertion or electrical continuity. Physical mounting compatibility depends on application-specific PCB or panel hole spacing, which is not specified in the provided data.

Q: What is the significance of the terminal width difference between 305130 (6.5 mm) and the substitutes (6.0 mm)?

A: Terminal width affects the physical footprint and spacing of the connector block. The 0.5 mm reduction in both substitute parts represents a minor dimensional change. Compatibility with existing mounting locations requires verification against application-specific mechanical drawings.

Q: Why does 304219 specify thermoplastic insulation instead of polyamide?

A: Material composition differences may reflect manufacturing process updates or design optimization within the AVK series. Both materials meet ROHS3 compliance and MSL 1 moisture sensitivity requirements. The original 305130 specifies polyamide with UL94 V-2 rating; 304219 does not provide explicit flammability documentation. Applications requiring specific flammability certification should reference 304139.

Q: Are both substitutes available in the same packaging as 305130?

A: The original 305130 packaging is not specified in the provided data. Both substitutes 304139 and 304219 are packaged in boxes. Packaging compatibility with existing supply chain processes requires verification against procurement specifications.

Q: What is the inventory status for these substitute parts?

A: Part 304139 has 992 units in current stock. Part 304219 has 1107 units in current stock. Both parts carry active product status, ensuring ongoing availability for procurement.

Q: Do all three parts meet RoHS and REACH compliance requirements?

A: All three parts (305130, 304139, and 304219) are ROHS3 compliant and REACH unaffected. Both substitutes maintain the same regulatory compliance profile as the original obsolete part.
