Substitute Part Grouping Explanation

Substitution for the Molex 0761550607 is determined by the following critical parameters:

Primary Substitution Criteria:

Number of positions: 192 (fixed requirement)
Connector type: Header, Male Pins (fixed requirement)
Mounting type: Through Hole (fixed requirement)
Termination method: Press-Fit (fixed requirement)
Row × Column configuration: 12 × 16 (fixed requirement)
Contact finish: Gold plating (fixed requirement)
Flammability rating: UL94 V-0 (fixed requirement)
RoHS compliance: ROHS3 or equivalent (fixed requirement)

Allowable Parameter Variations:

Pitch: 0.053" (1.35mm) for direct Molex substitutes; 0.075" (1.90mm) for TE Connectivity alternatives
Voltage rating: 30V (original) to 250V (TE alternatives) – higher ratings are acceptable
Operating temperature: -55°C to 85°C (original) to -65°C to 90°C (TE alternatives) – extended ranges are acceptable
Connector style: Impact (original) to High Speed (TE alternatives) – functional equivalence maintained
Packaging: Varies by part number (Tray, Tube, Bulk) – does not affect electrical or mechanical compatibility

Substitutes are grouped into two categories: direct Molex replacements maintaining identical pitch specifications, and TE Connectivity cross-compatible alternatives with modified pitch and enhanced electrical ratings.

Engineering Selection Recommendations

Direct Replacement (Pitch-Matched): The Molex 0761551607 is the primary direct substitute for the obsolete 0761550607. Both parts maintain identical pitch (0.053"/1.35mm), voltage rating (30V), and operating temperature range (-55°C to 85°C). The 0761551607 is currently in active production status with 954 units in stock, making it the preferred choice for applications requiring exact mechanical and electrical compatibility without PCB redesign.

Cross-Compatible Alternatives (Pitch-Modified): The TE Connectivity Z-PACK TinMan series (1934315-1, 1934316-1, 1934317-1, 1934318-1) provides functional equivalence with modified pitch specifications (0.075"/1.90mm). These parts offer enhanced electrical performance with 250V voltage rating and extended operating temperature range (-65°C to 90°C). Selection among TE alternatives is determined by packaging requirements and inventory availability. All TE alternatives maintain ROHS3 or RoHS compliance and UL94 V-0 flammability rating.

Compliance Considerations: All substitute parts meet RoHS3 or equivalent compliance standards and UL94 V-0 flammability requirements. The 1934318-1 offers the highest inventory availability (2240 units) among TE alternatives, supporting supply chain continuity for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761551607 be used as a direct replacement for the 0761550607? A: Yes. The 0761551607 maintains identical pitch (0.053"/1.35mm), connector configuration (192 positions, 12×16 layout), voltage rating (30V), and operating temperature range (-55°C to 85°C). No PCB modifications are required. The primary difference is product status: 0761551607 is active production while 0761550607 is obsolete.

Q: What is the key difference between Molex and TE Connectivity substitutes? A: Molex 0761551607 maintains the original 0.053" (1.35mm) pitch. TE Connectivity alternatives (1934315-1, 1934316-1, 1934317-1, 1934318-1) use 0.075" (1.90mm) pitch. TE parts also provide higher voltage rating (250V vs. 30V) and extended temperature range (-65°C to 90°C vs. -55°C to 85°C). Pitch modification requires PCB redesign.

Q: Are TE Connectivity parts suitable for applications originally designed for the Molex 0761550607? A: TE alternatives are functionally equivalent but require PCB layout modifications due to pitch difference. They are suitable only if the application can accommodate the larger 0.075" pitch spacing and if the enhanced electrical ratings (250V, 0.5A current rating) are compatible with system requirements.

Q: What packaging options are available for substitute parts? A: Molex 0761551607 is supplied in Tray packaging. TE Connectivity alternatives are available in Tube (1934315-1, 1934317-1, 1934318-1) or Bulk (1934316-1) packaging. Packaging selection does not affect electrical or mechanical performance.

Q: Which substitute part offers the best inventory availability? A: The TE Connectivity 1934318-1 provides the highest inventory level at 2240 units in stock, followed by 1934316-1 (1082 units) and 1934317-1 (1135 units). For direct pitch-matched replacement, Molex 0761551607 has 954 units available.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts meet RoHS3 or RoHS compliance standards. The Molex 0761551607, TE 1934315-1, and TE 1934318-1 are explicitly ROHS3 compliant. TE 1934316-1 and 1934317-1 are RoHS compliant.
