Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0760550608 is determined by the following critical parameters:

Direct Equivalent (Same Electrical & Mechanical Specifications):

• Molex 0760551608: Identical specifications to the main part with the exception of packaging (Tray vs. standard). This part maintains the same pitch (0.053"), position count (240), row/column configuration (15×16), and operating characteristics. Product status is Active, providing ongoing availability.

Cross-Manufacturer Alternatives (TE Connectivity Z-PACK TinMan Series):

• TE Connectivity 1934331-1, 1934332-1, 1934333-1, 1934334-1: These parts share the same 240-position count, 15×16 row/column configuration, through-hole mounting, and press-fit termination. However, they differ in pitch specification (0.075" vs. 0.053"), current rating (0.5A vs. unspecified), and voltage rating (250V vs. 30V). All are Active status with ROHS3 or RoHS compliance.

Substitution eligibility depends on PCB layout compatibility with the different pitch specification and electrical requirements of the target application.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No PCB Redesign Required): Select Molex 0760551608. This part is electrically and mechanically identical to the main part with Active product status, ensuring long-term availability and support. The only difference is packaging format (Tray). This is the preferred choice when PCB layout cannot be modified.

For Cross-Manufacturer Substitution (PCB Layout Modification Required): The TE Connectivity Z-PACK TinMan series (1934331-1, 1934332-1, 1934333-1, 1934334-1) can serve as alternatives only if the PCB layout is redesigned to accommodate the larger 0.075" pitch specification. These parts offer enhanced electrical ratings (250V vs. 30V, 0.5A current rating) and extended operating temperature range (-65°C to 90°C vs. -55°C to 85°C). All four TE parts maintain Active product status with RoHS or ROHS3 compliance. Selection among the four TE variants should be based on specific inventory requirements and compliance certifications needed for the application.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0760551608 as a direct drop-in replacement for Molex 0760550608? A: Yes. The 0760551608 is electrically and mechanically identical to the 0760550608. The only difference is packaging (Tray vs. standard). No PCB modifications are required.

Q: What is the main difference between the Molex Impact series and the TE Connectivity Z-PACK TinMan series? A: The primary difference is pitch specification. Molex Impact 0760550608 and 0760551608 use 0.053" (1.35mm) pitch, while TE Connectivity Z-PACK TinMan parts use 0.075" (1.90mm) pitch. This difference requires PCB layout redesign for cross-manufacturer substitution.

Q: Can I use TE Connectivity parts as substitutes without modifying my PCB? A: No. The TE Connectivity parts have a different pitch specification (0.075" vs. 0.053"), which means the connector footprint on the PCB must be redesigned. Direct physical substitution without PCB modification is not possible.

Q: Are all substitute parts RoHS compliant? A: Yes. Molex 0760551608 is ROHS3 compliant. TE Connectivity parts are either RoHS or ROHS3 compliant. All parts meet RoHS requirements.

Q: What are the electrical rating differences between the main part and TE Connectivity alternatives? A: The Molex 0760550608 has a 30V voltage rating with unspecified current rating. TE Connectivity Z-PACK TinMan parts have a 250V voltage rating and 0.5A current rating, providing higher electrical capacity for demanding applications.

Q: Which substitute part should I choose if I need the longest operating temperature range? A: TE Connectivity Z-PACK TinMan parts (1934331-1, 1934332-1, 1934333-1, 1934334-1) operate from -65°C to 90°C, compared to -55°C to 85°C for the Molex parts. However, this substitution requires PCB redesign due to pitch differences.

Q: Are there inventory differences among the TE Connectivity alternatives? A: Yes. Inventory levels vary: 1934331-1 (1854 Pcs), 1934332-1 (859 Pcs), 1934333-1 (924 Pcs), and 1934334-1 (1004 Pcs). Selection should consider both availability and compliance requirements for your application.
