Molex 0760550607 Equivalent & Substitute Parts

Part Overview

The Molex 0760550607 is a 240-position backplane connector header with male pins for through-hole PCB mounting. This Impact series connector features press-fit termination, gold-plated contacts, and is rated for 30V operation across an operating temperature range of -55°C to 85°C. The part is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0760550607 are grouped into two categories based on electrical and mechanical compatibility:

Category 1: Direct Molex Equivalent

Part 0760551607 maintains identical electrical and mechanical specifications to the original part, differing only in packaging (Tray vs. standard packaging) and product status (Active vs. Obsolete). This part is the primary direct replacement.

Category 2: TE Connectivity AMP Connectors (1934331-1, 1934332-1, 1934333-1, 1934334-1)

These parts share the same 240-position count, through-hole mounting, press-fit termination, gold contact finish, and black color. However, they operate under different electrical parameters: pitch of 0.075" (1.90mm) instead of 0.053" (1.35mm), voltage rating of 250V instead of 30V, current rating of 0.5A, and extended operating temperature range of -65°C to 90°C. These represent functional alternatives for applications where the higher voltage and current ratings are acceptable and the larger pitch is compatible with PCB layout.

Substitution is determined by matching: connector type (Header, Male Pins), number of positions (240), mounting method (Through Hole), termination style (Press-Fit), contact finish (Gold), color (Black), and compliance certifications (UL94 V-0, ROHS3 or RoHS Compliant).

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): Select Molex 0760551607. This part is the active equivalent of the obsolete 0760550607, maintaining all electrical and mechanical parameters. It carries ROHS3 compliance and active product status, ensuring long-term availability and supply chain continuity.

For Alternative Applications (Modified Electrical Parameters): The TE Connectivity AMP Connectors series (1934331-1, 1934332-1, 1934333-1, 1934334-1) are suitable when PCB layout accommodates the larger 0.075" (1.90mm) pitch and when the application requires higher voltage (250V) and current (0.5A) ratings. All four TE parts are active products with UL94 V-0 flammability rating and MSL 1 classification. Selection among the four TE variants should be based on RoHS certification requirements: parts 1934331-1 and 1934333-1 carry ROHS3 compliance, while 1934332-1 and 1934334-1 carry standard RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0760551607 as a direct replacement for 0760550607? A: Yes. The 0760551607 is electrically and mechanically identical to the 0760550607. The only differences are packaging format (Tray) and product status (Active vs. Obsolete). It is the recommended direct replacement.

Q: What is the main difference between the Molex and TE Connectivity substitute parts? A: The Molex 0760551607 maintains the original 0.053" (1.35mm) pitch and 30V rating. The TE Connectivity parts (1934331-1 through 1934334-1) feature a larger 0.075" (1.90mm) pitch, higher voltage rating of 250V, and a specified current rating of 0.5A. These differences require PCB layout verification before substitution.

Q: Are all substitute parts RoHS compliant? A: All substitute parts meet RoHS requirements. The Molex 0760551607 and TE parts 1934331-1 and 1934333-1 carry ROHS3 compliance. TE parts 1934332-1 and 1934334-1 carry standard RoHS compliance. Selection should align with your application's compliance requirements.

Q: Can I use TE Connectivity parts in a design originally specified for Molex 0760550607? A: Only if your PCB layout and electrical design accommodate the 0.075" (1.90mm) pitch instead of 0.053" (1.35mm), and if the higher voltage and current ratings are compatible with your application. PCB footprint verification is required.

Q: What is the inventory status of these parts? A: Molex 0760551607 has 1002 units in stock. TE Connectivity parts have the following inventory: 1934331-1 (1854 units), 1934332-1 (859 units), 1934333-1 (924 units), and 1934334-1 (1004 units). All are available as new original stock.
