Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800685 is determined by strict alignment of the following critical parameters:

Connector Configuration: 34 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
Contact Specifications: Male pin, square contact shape
Mounting and Termination: Through-hole solder termination with push-pull fastening
Style Compatibility: Board-to-board or cable interconnection capability
Compliance: UL94 V-0 flammability rating and ROHS3 compliance

All identified substitute parts meet these core electrical and mechanical parameters. Variations in contact length, insulation material, contact finish composition, and operating temperature ranges are secondary parameters that do not prevent functional substitution within the specified connector class.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with UL94 V-0 flammability requirements and ROHS3 standards, ensuring regulatory alignment with the original Molex 0702800685.

TE Connectivity 6-146256-7 provides direct substitution with matching insulation height (0.090") and copper alloy contact material. This part is suitable for applications requiring the closest dimensional profile to the original design.

Amphenol ICC 67997-134HLF and 77313-101-34LF offer extended operating temperature ranges (-65°C to 130°C) compared to the original specification, with phosphor bronze contacts and increased insulation height (0.100"). These parts are appropriate for thermal-demanding applications.

Sullins PBC17DAAN and PEC17DAAN provide cost-effective alternatives with phosphor bronze contacts, polybutylene terephthalate insulation, and operating temperature ranges of -65°C to 125°C. PEC17DAAN features tin mating contact finish, while PBC17DAAN maintains gold mating finish. Both are suitable for general-purpose and cost-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0702800685 with any of these parts without PCB redesign?

A: All substitute parts share identical pitch (0.100"), row spacing (0.100"), position count (34), and mounting type (through-hole solder). However, variations in overall contact length (ranging from 0.425" to 0.505") and insulation height (0.090" to 0.100") may affect board-level clearances and mating depth. Verify mechanical fit within your specific PCB layout before implementation.

Q: What is the difference between the Amphenol ICC BERGSTIK® II and BERGSTIK® series?

A: The BERGSTIK® II (67997-134HLF) is classified as a Header without breakaway capability, while the BERGSTIK® (77313-101-34LF) includes breakaway functionality. Both operate at -65°C to 130°C with phosphor bronze contacts and gold mating finish. Select based on your application's requirement for individual pin separation.

Q: Are the Sullins PBC17DAAN and PEC17DAAN interchangeable?

A: Both parts are mechanically and electrically compatible with identical pitch, position count, and mounting specifications. The primary difference is mating contact finish: PBC17DAAN features gold finish while PEC17DAAN features tin finish. Selection depends on your connector interface requirements and environmental exposure conditions.

Q: What is the impact of contact material differences (Copper Alloy vs. Phosphor Bronze)?

A: Both materials are acceptable for this connector class. Copper alloy (Molex 0702800685 and TE Connectivity 6-146256-7) and phosphor bronze (Amphenol ICC and Sullins parts) provide equivalent electrical conductivity and mechanical durability. Phosphor bronze offers slightly enhanced spring characteristics and wear resistance in high-cycle mating applications.

Q: Do all substitute parts meet the same compliance standards?

A: All parts are UL94 V-0 rated and RoHS compliant. TE Connectivity 6-146256-7 and Amphenol ICC 77313-101-34LF and Sullins parts are ROHS3 compliant. Amphenol ICC 67997-134HLF is RoHS compliant. Verify specific REACH and ECCN requirements for your end-use application and geographic market.

Q: Which substitute part offers the widest operating temperature range?

A: Amphenol ICC 67997-134HLF and 77313-101-34LF both support -65°C to 130°C operation, providing the widest temperature envelope. This exceeds the Molex original specification and the TE Connectivity and Sullins alternatives, which operate to 105°C, 125°C, and 125°C respectively.
