Key Parameters

Substitute Part Grouping Explanation

The Molex 0761503020 qualifies as a direct substitute for the 0761502020 based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Position count: 180 positions
• Physical layout: 18 rows × 10 columns
• Mounting configuration: Board edge, through hole, right angle
• Termination method: Press-fit
• Contact finish: Gold plating at 30.0µin thickness
• Operating temperature range: -55°C to 85°C
• Voltage rating: 30V
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

Distinguishing Factor: The 0761503020 includes a specified pitch of 0.053" (1.35mm), which was not documented for the original part. The substitute maintains active product status, ensuring continued availability and support compared to the obsolete 0761502020.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761503020 is the appropriate substitute for the obsolete 0761502020. Both components maintain identical electrical and mechanical specifications across all critical parameters, including connector configuration, position count, mounting method, contact materials, and environmental ratings.

The transition from the obsolete 0761502020 to the active 0761503020 ensures long-term component availability and supply chain continuity. Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial backplane applications.

The documented pitch specification of 0.053" (1.35mm) for the 0761503020 provides explicit dimensional confirmation for design verification and PCB layout purposes.

Frequently Asked Questions (FAQ)

Q: Can the 0761503020 directly replace the 0761502020 in existing designs?

A: Yes. The 0761503020 maintains identical electrical and mechanical specifications across all critical parameters: 180-position configuration, 18×10 layout, board edge right-angle mounting, press-fit termination, gold contact finish, operating temperature range, and voltage rating. No design modifications are required.

Q: What is the primary reason for substitution?

A: The 0761502020 is classified as obsolete. The 0761503020 is an active product within the same Impact 76150 series, ensuring continued availability and manufacturer support.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 compliant, carry UL94 V-0 flammability certification, and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Does packaging differ between these parts?

A: The 0761502020 packaging is not specified in available documentation. The 0761503020 is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Is the pitch specification critical for compatibility?

A: The 0761503020 specifies a pitch of 0.053" (1.35mm). This dimension should be verified against your PCB layout and connector mating specifications to confirm compatibility with existing board designs.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 0761502020 and 0761503020 are manufactured by Molex and belong to the Impact 76150 connector series.
