Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 9-103329-0 is the direct equivalent substitute for the obsolete 7-104349-7. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with TE Connectivity, ensuring ongoing availability, technical support, and supply chain continuity. The main part is classified as obsolete, creating supply risk for new production and maintenance applications.

Electrical and Mechanical Equivalence: All critical electrical parameters (40-position configuration, 0.100" pitch, 3A current rating, -65°C to 105°C operating range) and mechanical parameters (through-hole right-angle mounting, contact dimensions, insulation height) are identical between the main part and substitute.

Compliance and Certification: Both parts maintain identical compliance certifications including UL94 V-0 flammability rating, RoHS compliance, and identical ECCN and HTSUS classifications. Moisture sensitivity level (MSL 1) is identical, indicating no special handling requirements for either part.

Termination Compatibility: The substitute part supports solder termination, which is the primary termination method for the main part. The main part specification includes both press-fit and solder termination options; the substitute supports the solder termination method used in standard applications.

Inventory and Availability: The substitute part (9-103329-0) has significantly higher inventory availability (3435 pieces) compared to the main part (953 pieces), providing improved supply security for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 9-103329-0 be used as a direct replacement for the 7-104349-7 in existing designs?

A: Yes. The 9-103329-0 is electrically and mechanically equivalent to the 7-104349-7 across all critical parameters including connector type, contact configuration, pitch, current rating, operating temperature range, and mounting specifications. Both parts are from the same AMPMODU Mod II series and maintain identical contact dimensions and finishes.

Q: What is the primary difference between these two parts?

A: The main difference is product status. The 7-104349-7 is obsolete, while the 9-103329-0 is an active product. The 9-103329-0 also has higher inventory availability and is packaged in bulk format. Both parts are functionally equivalent for board-to-board and cable interconnection applications.

Q: Are there any termination method differences between these parts?

A: The 7-104349-7 specification includes both press-fit and solder termination options. The 9-103329-0 supports solder termination. For applications using solder termination, the parts are fully compatible. Applications requiring press-fit termination should reference the main part specification.

Q: Do these parts have identical compliance certifications?

A: Yes. Both parts maintain identical UL94 V-0 flammability ratings, RoHS compliance status, and identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Moisture sensitivity level is identical at MSL 1 (Unlimited), indicating no special storage or handling requirements.

Q: What is the pitch specification for these connectors?

A: Both parts operate at 0.100" (2.54mm) pitch, which is the standard spacing for AMPMODU Mod II series rectangular connectors. This pitch specification determines compatibility with mating connectors and PCB layout requirements.

Q: Are the contact dimensions identical between these parts?

A: Yes. Contact length for mating is 0.230" (5.84mm), contact length for post is 0.120" (3.05mm), and insulation height is 0.138" (3.50mm) for both parts. Contact finish is tin with 100.0µin (2.54µm) thickness on both mating and post surfaces for both parts.

Q: What is the current rating for these connectors?

A: Both parts are rated for 3A continuous current. This rating applies to each individual contact within the 40-position configuration.

Q: Are these parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -65°C to 105°C, making them suitable for industrial and commercial applications with equivalent thermal performance.
