Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0761551605 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

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

Secondary Parameters Allowing Variation:

• Pitch: 0.053" (1.35mm) in main part; substitutes may vary to 0.075" (1.90mm) based on application requirements
• Number of Rows/Columns: 12 × 16 configuration maintained across all parts
• Operating Temperature Range: Main part -55°C ~ 85°C; substitutes -65°C ~ 90°C (extended range acceptable)
• Voltage Rating: Main part 30V; substitutes 250V (higher rating acceptable)
• Current Rating: Main part unspecified; substitutes 0.5A (specification acceptable)

The identified substitutes (TE Connectivity 1934316-1 and 1934318-1) maintain all primary compatibility criteria while offering extended operating temperature ranges and higher voltage ratings, making them suitable alternatives for applications requiring enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

Molex 0761551605 (Primary Part) Select this part when the original specification calls for 0.053" (1.35mm) pitch and 30V voltage rating. The part is active in production with established supply availability. ROHS3 compliance and UL94 V-0 flammability rating meet standard industrial requirements.

TE Connectivity 1934316-1 (Substitute - Bulk Packaging) This substitute is suitable for applications where the 0.075" (1.90mm) pitch is acceptable and extended operating temperature range (-65°C ~ 90°C) is beneficial. The higher voltage rating (250V) provides additional design margin. Bulk packaging accommodates high-volume production requirements. RoHS compliance is confirmed; REACH status is vendor-defined.

TE Connectivity 1934318-1 (Substitute - Tube Packaging) This substitute offers identical electrical specifications to part 1934316-1 with extended temperature range and higher voltage rating. Tube packaging is suitable for automated assembly processes. ROHS3 compliance and highest inventory availability (2240 units) support production continuity. REACH status is vendor-defined.

Selection Criteria:

• Pitch requirement: 0.053" (1.35mm) requires Molex 0761551605; 0.075" (1.90mm) accommodates TE Connectivity substitutes
• Temperature extremes: Applications requiring -65°C operation require TE Connectivity substitutes
• Voltage margin: Applications exceeding 30V require TE Connectivity substitutes (250V rating)
• Packaging preference: Tray (Molex), Bulk (1934316-1), or Tube (1934318-1)
• Supply availability: TE Connectivity 1934318-1 offers highest stock level

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1934316-1 and 1934318-1 be used interchangeably with Molex 0761551605?

A: Direct interchangeability depends on PCB layout and pitch requirements. The Molex part uses 0.053" (1.35mm) pitch, while TE Connectivity substitutes use 0.075" (1.90mm) pitch. If the PCB is designed for 0.053" pitch, the TE Connectivity parts cannot be used without PCB redesign. If the application can accommodate 0.075" pitch, the TE Connectivity parts are electrically and mechanically compatible.

Q: What is the primary difference between TE Connectivity 1934316-1 and 1934318-1?

A: Both parts are electrically and mechanically identical. The difference is packaging: 1934316-1 is supplied in bulk packaging, while 1934318-1 is supplied in tube packaging. Select based on assembly process requirements and inventory management preferences.

Q: Are the TE Connectivity substitutes suitable for high-temperature applications?

A: Yes. TE Connectivity substitutes operate from -65°C to 90°C, compared to the Molex part's -55°C to 85°C range. The extended upper temperature limit (90°C vs. 85°C) and lower temperature limit (-65°C vs. -55°C) make TE Connectivity substitutes suitable for applications requiring wider temperature margins.

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. Molex 0761551605 is ROHS3 compliant. TE Connectivity 1934316-1 is RoHS compliant. TE Connectivity 1934318-1 is ROHS3 compliant. All parts meet RoHS environmental compliance standards.

Q: What is the voltage rating difference, and does it affect part selection?

A: Molex 0761551605 has a 30V rating; TE Connectivity substitutes have a 250V rating. The higher voltage rating in TE Connectivity parts provides additional design margin and is suitable for applications with voltage transients or future design upgrades. If the application operates below 30V, either part is acceptable.

Q: How does pitch affect connector compatibility?

A: Pitch is the center-to-center distance between adjacent pins. Molex 0761551605 uses 0.053" (1.35mm) pitch; TE Connectivity substitutes use 0.075" (1.90mm) pitch. PCB hole patterns must match the connector pitch exactly. Pitch mismatch prevents proper connector seating and electrical contact. PCB redesign is required to change pitch.

Q: Which part should be selected for maximum inventory availability?

A: TE Connectivity 1934318-1 offers the highest inventory level at 2240 units in stock, compared to 1082 units for 1934316-1 and 978 units for Molex 0761551605. If supply continuity is a priority and pitch requirements allow, 1934318-1 is the optimal choice.
