Substitute Part Grouping Explanation

Substitution compatibility for the Molex 0022303083 is determined by the following critical parameters:

Pitch and Position Count: Both the main part and substitute must maintain 0.100" (2.54mm) pitch with 8 positions in a single row to ensure mechanical fit and electrical continuity.
Connector Type and Contact Type: Header configuration with male pin contacts is required for board-to-board or cable applications.
Mounting Method: Through-hole mounting is mandatory for PCB integration.
Fastening Mechanism: Push-pull fastening type ensures consistent mating and demating operations.
Shrouding Configuration: Unshrouded design maintains the same form factor and accessibility.
Compliance Standards: UL94 V-0 flammability rating and RoHS compliance ensure regulatory and safety alignment.

The TE Connectivity AMP Connectors 826648-8 meets all these critical substitution criteria, making it a valid equivalent for the Molex 0022303083 in applications requiring 8-position 2.54mm pitch header connectors.

Engineering Selection Recommendations

Both the Molex 0022303083 and TE Connectivity 826648-8 are active products with full regulatory compliance. The Molex part carries ROHS3 Compliant status, while the TE Connectivity substitute is RoHS Compliant. Both connectors meet UL94 V-0 flammability requirements and maintain MSL 1 (Unlimited) moisture sensitivity ratings, suitable for general purpose, automotive, medical, and telecommunications applications.

The TE Connectivity 826648-8 offers higher current rating (5A) and specified operating temperature range (-65°C ~ 105°C), with gold-plated mating contacts and brass contact material. The Molex 0022303083 features kinked pin termination with tin plating. Both parts are mechanically and electrically interchangeable for 8-position 2.54mm pitch header applications.

Selection between these parts should be based on supply chain availability, specific application temperature requirements, and contact finish preferences. The TE Connectivity part provides greater inventory availability (6760 units versus 1043 units).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 826648-8 directly replace the Molex 0022303083 in existing designs?

A: Yes. Both connectors share identical pitch (0.100"/2.54mm), position count (8), mounting type (through-hole), and fastening mechanism (push-pull). The mechanical and electrical interfaces are compatible for board-to-board and cable applications.

Q: What are the differences in contact materials between these two connectors?

A: The Molex 0022303083 uses tin-plated contacts, while the TE Connectivity 826648-8 features gold-plated mating contacts with brass contact material. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments.

Q: Are there temperature operating range differences?

A: The TE Connectivity 826648-8 specifies an operating temperature range of -65°C to 105°C. The Molex 0022303083 does not provide an operating temperature specification in the available data.

Q: Do both connectors meet the same compliance standards?

A: Both connectors are UL94 V-0 rated and maintain MSL 1 (Unlimited) moisture sensitivity levels. The Molex part is ROHS3 Compliant, while the TE Connectivity part is RoHS Compliant. Both meet ECCN EAR99 and HTSUS 8536.69.4040 classifications.

Q: What is the difference in insulation material?

A: The Molex 0022303083 uses glass-filled polyamide (PA/nylon), while the TE Connectivity 826648-8 uses polybutylene terephthalate (PBT). Both materials provide UL94 V-0 flammability performance and are suitable for the specified applications.

Q: Which connector has better supply availability?

A: The TE Connectivity 826648-8 has significantly higher inventory (6760 units) compared to the Molex 0022303083 (1043 units), making it a more readily available alternative for high-volume production requirements.
