Substitute Part Grouping Explanation

Substitute parts for the Molex 0761552607 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

• Number of Positions: 192
• Connector Type: Header, Male Pins
• Mounting Type: Through Hole
• Termination: Press-Fit
• Number of Rows: 12
• Number of Columns: 16
• Contact Finish: Gold
• Color: Black
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Pitch: 0.053" (1.35mm) primary; 0.075" (1.90mm) acceptable for mechanical compatibility
• Operating Temperature: -55°C ~ 85°C minimum; extended ranges acceptable
• Voltage Rating: 30V minimum; higher ratings acceptable
• Product Status: Active preferred over obsolete

The Molex 0761553607 is a direct manufacturer equivalent with identical electrical and mechanical specifications, differing only in packaging (Tray vs. standard) and product status (Active vs. Obsolete). The TE Connectivity 1934316-1 is a manufacturer-recommended substitute that maintains core 192-position, 12x16 configuration with through-hole press-fit termination but operates at different pitch spacing (0.075" vs. 0.053"), higher voltage rating (250V vs. 30V), and extended temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

Molex 0761553607 is the preferred direct equivalent for the obsolete Molex 0761552607. This part maintains identical electrical and mechanical specifications including pitch, voltage rating, temperature range, and connector configuration. The primary difference is product status (Active vs. Obsolete) and packaging format (Tray). This substitute ensures full compatibility with existing PCB designs and connector mating interfaces without requiring layout modifications. ROHS3 compliance and UL94 V-0 flammability rating are maintained.

TE Connectivity 1934316-1 is a manufacturer-recommended substitute suitable for applications where PCB layout modifications are acceptable. This part differs in pitch spacing (0.075" vs. 0.053"), which requires PCB redesign for the connector footprint. The substitute provides enhanced electrical performance with 250V voltage rating (vs. 30V) and extended operating temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C). Current rating specification (0.5A) is provided for the TE part. RoHS compliance and UL94 V-0 flammability rating are maintained. This option is suitable for new designs or redesign scenarios where the pitch change can be accommodated.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761553607 be used as a direct replacement for the Molex 0761552607?

A: Yes. The Molex 0761553607 is a direct equivalent with identical connector specifications. The only differences are packaging format (Tray vs. standard) and product status (Active vs. Obsolete). No PCB modifications are required.

Q: What is the primary difference between the Molex 0761552607 and the TE Connectivity 1934316-1?

A: The primary difference is pitch spacing. The Molex part uses 0.053" (1.35mm) pitch, while the TE Connectivity part uses 0.075" (1.90mm) pitch. This difference requires PCB footprint redesign if substituting the TE part. Both maintain 192-position, 12x16 configuration with through-hole press-fit termination.

Q: Are there compliance or certification differences between the substitute parts?

A: All three parts meet UL94 V-0 flammability requirements and MSL 1 (Unlimited) moisture sensitivity levels. The Molex parts are ROHS3 compliant, while the TE Connectivity part is RoHS compliant. All parts are suitable for applications requiring these certifications.

Q: Which substitute should be selected for a new design?

A: For new designs, the TE Connectivity 1934316-1 is the manufacturer-recommended option. It provides enhanced electrical performance with 250V voltage rating and extended temperature range (-65°C ~ 90°C). The larger pitch spacing (0.075") may offer improved signal integrity for high-speed applications.

Q: Can the TE Connectivity 1934316-1 be used in existing PCBs designed for the Molex 0761552607?

A: No. The pitch difference (0.075" vs. 0.053") makes the TE part mechanically incompatible with existing PCB layouts. PCB redesign is required to accommodate the different connector footprint.

Q: What is the inventory status for these parts?

A: Molex 0761552607 (obsolete): 979 pcs in stock. Molex 0761553607 (active): 964 pcs in stock. TE Connectivity 1934316-1 (active): 1082 pcs in stock.
