Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761450107 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Connector series: Impact 76145
• Number of positions: 180
• Pitch: 0.053" (1.35mm)
• Array configuration: 18 rows × 10 columns
• Connector type: Header, Male Pins
• Mounting type: Through Hole
• Termination method: Press-Fit
• Contact finish: Gold
• Voltage rating: 30V
• Operating temperature range: -55°C to +85°C
• Material flammability: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The substitute part Molex 0761451107 meets all mandatory criteria. The primary distinction is product status (Active vs. Obsolete) and packaging format (Tray vs. standard packaging), neither of which affects electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761451107 is a direct functional equivalent to the 0761450107. Selection between these parts should be based on the following factors:

Product Status Consideration: The 0761450107 is obsolete, while the 0761451107 is active. For new designs, ongoing production, or long-term system support, the active part number 0761451107 is the appropriate choice to ensure continued availability and supply chain stability.

Compliance and Certification: Both parts maintain identical compliance profiles, including ROHS3 certification and UL94 V-0 flammability rating. No additional qualification or testing is required when transitioning from the obsolete to the active part number.

Packaging Consideration: The 0761451107 is supplied in Tray packaging, which may differ from the original packaging of the 0761450107. Verify that tray packaging is compatible with your receiving, storage, and assembly processes.

Electrical and Mechanical Compatibility: All electrical parameters (voltage rating, contact finish, operating temperature range) and mechanical parameters (pitch, array configuration, mounting type, termination method) are identical. Direct substitution is electrically and mechanically sound.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761451107 be used as a direct replacement for the 0761450107 in existing designs?

A: Yes. The 0761451107 is electrically and mechanically identical to the 0761450107 across all specified parameters. No design modifications are required for substitution.

Q: What is the primary reason for substituting the 0761450107?

A: The 0761450107 is obsolete. The 0761451107 is the active equivalent within the same Impact 76145 series, ensuring ongoing availability and supply chain continuity.

Q: Are there any differences in contact performance or reliability between these parts?

A: No. Both parts feature identical gold contact finish (30.0µin thickness), voltage rating (30V), and operating temperature range (-55°C to +85°C). Contact performance and reliability characteristics are equivalent.

Q: Does the packaging difference (Tray vs. standard) affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. However, verify that tray packaging is compatible with your receiving, storage, and assembly workflows.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0761450107 and 0761451107 are ROHS3 compliant and maintain identical environmental compliance profiles.

Q: What is the pitch and array configuration of these connectors?

A: Both parts feature a 0.053" (1.35mm) pitch with an 18-row × 10-column array, providing 180 total positions configured as 60 differential pairs.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for operation from -55°C to +85°C. Applications requiring operation outside this range require alternative connector selection.
