Key Parameters

Substitute Part Grouping Explanation

The Molex 0760553103 qualifies as a direct substitute for the 0760552103 based on strict parameter equivalence. Both parts share identical specifications across all critical electrical and mechanical parameters:

Key Substitution Parameters:

• Connector type, style, and position count (150-position Impact header, male pins)
• Physical configuration (15 rows × 10 columns, 0.053" pitch)
• Mounting and termination method (through-hole, press-fit)
• Contact material and finish (gold, 30.0µin thickness)
• Electrical ratings (30V, -55°C to 85°C operating range)
• Compliance certifications (UL94 V-0, ROHS3, MSL 1)

The primary distinction is product status: the 0760552103 is obsolete, while the 0760553103 maintains active status with higher inventory availability (848 pcs vs. 834 pcs). Packaging differs (tray vs. standard), but this does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0760553103 is the appropriate selection for applications currently specified with the 0760552103. The substitute part maintains full electrical and mechanical compatibility with identical parameter specifications. The transition from obsolete to active product status ensures long-term supply chain viability and compliance with current manufacturing standards.

Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial backplane applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture sensitivity concerns for both variants.

For new designs and production planning, the 0760553103 should be specified to ensure continued availability and support. Existing inventory of the 0760552103 may be utilized in current production runs without functional or compliance impact.

Frequently Asked Questions (FAQ)

Q: Can the 0760553103 directly replace the 0760552103 in existing PCB designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No PCB layout modifications are required. The connector footprint, pin pitch (0.053"), row/column configuration (15×10), and mounting method (through-hole, press-fit) are identical.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. The 0760552103 is obsolete, while the 0760553103 is active. Packaging also differs (standard vs. tray), but this does not affect component functionality or compatibility.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical certifications: ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Electrical ratings (30V, -55°C to 85°C) and contact specifications (gold finish, 30.0µin thickness) are identical.

Q: Which part should be specified for new designs?

A: The 0760553103 should be specified for new designs due to its active product status and improved long-term availability. The obsolete status of the 0760552103 may result in supply constraints for future production requirements.

Q: Are there any performance differences in signal integrity or electrical characteristics?

A: No. Both parts are from the same Impact 76055 series with identical electrical specifications. Contact material, finish thickness, voltage rating, and operating temperature range are identical, ensuring equivalent performance in 50 differential pair configurations.
