Amphenol ICC 76345-305-08LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76345-305-08LF is an active, through-hole right-angle rectangular connector header with 8 positions at 2.54mm pitch. This BERGSTIK® series component is designed for board-to-board applications requiring solder termination and push-pull fastening. The part is RoHS compliant with MSL 1 rating, indicating broad compatibility across industrial and commercial applications. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in designs where form factor and performance requirements remain constant.

Substitute Part Grouping Explanation

Substitution eligibility for the 76345-305-08LF is determined by strict alignment of core mechanical and electrical parameters. The following criteria establish functional equivalence:

Primary Substitution Criteria:

• Connector type: Header with male pin contacts
• Pitch specification: 0.100" (2.54mm) mating pitch
• Position count: 8 positions in 2-row configuration
• Row spacing: 0.100" (2.54mm)
• Mounting: Through-hole, right-angle orientation
• Termination: Solder connection
• Fastening: Push-pull mechanism
• Shrouding: Unshrouded design
• Style: Board-to-board application

The TE Connectivity AMP Connectors 826634-4 meets all primary substitution criteria. Both parts share identical pitch, position count, row configuration, mounting type, and termination method. Both maintain UL94 V-0 flammability compliance and MSL 1 moisture sensitivity rating. Differences in contact material, contact finish, insulation material, and insulation color do not preclude substitution when electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the 76345-305-08LF and 826634-4 are active products with current manufacturing status, ensuring long-term availability and supply chain stability. Both components maintain UL94 V-0 flammability compliance and MSL 1 moisture sensitivity rating, supporting deployment in standard industrial and commercial environments.

The 76345-305-08LF uses phosphor bronze contacts with tin finish, while the 826634-4 employs brass contacts with gold finish. The 826634-4 provides specified operating temperature range (-65°C ~ 105°C) and current rating (5A), whereas the 76345-305-08LF does not provide these parameters in the available documentation. The 826634-4 features breakaway capability, offering additional design flexibility for applications requiring modular connector segments.

Selection between these parts depends on specific application requirements. When operating temperature and current specifications are critical design parameters, the 826634-4 provides explicit ratings. When contact finish preference or insulation material composition is specified in design documentation, verify alignment with the selected part. Both components satisfy identical mechanical interface requirements and are suitable for board-to-board solder-terminated applications at 2.54mm pitch.

Frequently Asked Questions (FAQ)

Q: Can the 826634-4 directly replace the 76345-305-08LF in existing PCB designs?

A: Yes, provided the PCB footprint accommodates the through-hole right-angle mounting pattern. Both parts share identical pitch (2.54mm), position count (8), row configuration (2 rows), and mounting orientation. Verify that the PCB layout does not depend on specific contact finish or insulation material properties unique to the original part.

Q: What is the significance of the contact finish difference (tin vs. gold)?

A: Contact finish affects electrical performance and environmental resistance. Tin finish provides cost-effective performance in standard applications. Gold finish offers superior corrosion resistance and lower contact resistance, beneficial in high-reliability or harsh environment applications. Selection depends on application requirements and design specifications.

Q: Does the breakaway feature of the 826634-4 affect compatibility?

A: The breakaway feature is an additional capability that does not compromise compatibility with designs requiring fixed 8-position headers. The breakaway mechanism allows optional segmentation but does not interfere with standard board-to-board mating when used as a complete 8-position assembly.

Q: Are there differences in solder joint reliability between these parts?

A: Both parts use solder termination with square contact geometry and push-pull fastening. Differences in contact material (phosphor bronze vs. brass) and insulation material (thermoplastic vs. PBT) may influence thermal characteristics during reflow soldering. Consult manufacturer datasheets for specific thermal profiles if solder process parameters are critical to your manufacturing process.

Q: What does MSL 1 rating mean for component handling?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture-controlled storage requirements. Both parts can be stored and handled under standard warehouse conditions without special desiccant packaging or humidity control measures.

Q: Is the 826634-4 suitable for applications where operating temperature specification is required?

A: Yes. The 826634-4 provides an explicit operating temperature range of -65°C ~ 105°C. If your application requires documented temperature performance, this specification supports design validation. The 76345-305-08LF does not provide operating temperature data in available documentation.
