Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0760559608 are qualified based on the following critical parameters that determine functional interchangeability:

Matching Parameters (Required for Substitution):

• Number of Positions: 240 (all substitutes maintain this specification)
• Connector Type: Header, Male Pins (consistent across all alternatives)
• Matrix Configuration: 15 Rows × 16 Columns (identical layout)
• Mounting Type: Through Hole (same PCB integration method)
• Termination: Press-Fit (identical connection mechanism)
• Contact Finish: Gold (same surface treatment)
• Flammability Rating: UL94 V-0 (equivalent safety certification)
• RoHS Compliance: ROHS3 or RoHS Compliant (regulatory alignment)

Differing Parameters (Application-Dependent):

• Pitch: Molex uses 0.053" (1.35mm); TE Connectivity substitutes use 0.075" (1.90mm)
• Voltage Rating: Molex rated 30V; TE Connectivity substitutes rated 250V
• Current Rating: Molex unspecified; TE Connectivity substitutes rated 0.5A
• Operating Temperature: Molex -55°C to 85°C; TE Connectivity -65°C to 90°C
• Connector Style: Molex Impact Guide Right; TE Connectivity High Speed

The TE Connectivity AMP Connectors series (1934331-1, 1934332-1, 1934334-1) provide higher voltage and current ratings with extended temperature range, suitable for applications requiring enhanced electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between the Molex 0760559608 and TE Connectivity AMP Connectors substitutes depends on application-specific electrical and mechanical requirements:

Molex 0760559608 Selection Criteria:

• Applications requiring 0.053" (1.35mm) pitch for high-density interconnect designs
• Systems operating at 30V or lower voltage levels
• Operating temperature range limited to -55°C to 85°C
• Tray packaging preferred for manufacturing processes
• Impact connector style with guide-right orientation required

TE Connectivity 1934331-1, 1934332-1, 1934334-1 Selection Criteria:

• Applications requiring 0.075" (1.90mm) pitch for standard-density interconnect
• Systems requiring 250V voltage rating or 0.5A current capacity
• Extended operating temperature range of -65°C to 90°C necessary
• Tube packaging suitable for component handling and storage
• High-speed connector performance required
• ROHS3 compliance (1934331-1) or RoHS compliance (1934332-1, 1934334-1) mandated

All substitute parts maintain identical 240-position configuration, through-hole mounting, press-fit termination, and UL94 V-0 flammability certification. PCB layout modifications are required when substituting between 0.053" and 0.075" pitch specifications due to different hole spacing.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity parts 1934331-1, 1934332-1, and 1934334-1 directly replace the Molex 0760559608 without PCB modification?

A: Direct replacement without PCB modification is not possible. The Molex 0760559608 uses 0.053" (1.35mm) pitch, while TE Connectivity substitutes use 0.075" (1.90mm) pitch. This difference requires PCB layout redesign to accommodate the different hole spacing pattern. Both maintain 240 positions in a 15×16 matrix, but the physical footprint differs.

Q: What are the key electrical differences between the Molex and TE Connectivity options?

A: The Molex 0760559608 is rated for 30V with unspecified current capacity. TE Connectivity substitutes are rated for 250V and 0.5A per contact. Applications requiring higher voltage or current specifications must use TE Connectivity parts. Lower-voltage applications can use either option, provided pitch and temperature requirements are met.

Q: Are all three TE Connectivity part numbers (1934331-1, 1934332-1, 1934334-1) electrically and mechanically identical?

A: The three TE Connectivity parts are functionally equivalent. All share identical electrical ratings (250V, 0.5A), mechanical configuration (240 positions, 15×16 matrix, 0.075" pitch), and operating temperature range (-65°C to 90°C). Differences exist only in RoHS compliance status: 1934331-1 is ROHS3 Compliant, while 1934332-1 and 1934334-1 are RoHS Compliant. Selection depends on specific regulatory requirements.

Q: What is the impact of pitch difference on connector performance?

A: Pitch determines the physical spacing between contact centers and directly affects PCB hole pattern, trace routing density, and mechanical fit. The 0.053" pitch of the Molex connector enables higher density layouts compared to the 0.075" pitch of TE Connectivity parts. Substitution requires complete PCB redesign; no adapter solutions are applicable for backplane connectors of this type.

Q: Are temperature operating ranges compatible between the Molex and TE Connectivity options?

A: The Molex 0760559608 operates from -55°C to 85°C. TE Connectivity substitutes operate from -65°C to 90°C, providing extended range at both lower and upper temperature limits. Applications within the Molex temperature range can use either option. Applications requiring -65°C minimum or 90°C maximum operation must use TE Connectivity parts.

Q: What packaging differences exist, and how do they affect procurement?

A: The Molex 0760559608 is supplied in Tray packaging (941 units in stock). TE Connectivity substitutes are supplied in Tube packaging (1854, 859, and 1004 units respectively in stock). Packaging affects handling, storage, and integration into manufacturing processes. Verify packaging compatibility with assembly equipment and logistics requirements before selection.

Q: Do all parts meet the same flammability and compliance standards?

A: All parts carry UL94 V-0 flammability certification. RoHS compliance differs: Molex is ROHS3 Compliant; TE Connectivity 1934331-1 is ROHS3 Compliant; TE Connectivity 1934332-1 and 1934334-1 are RoHS Compliant. For applications requiring ROHS3 specifically, use Molex 0760559608 or TE Connectivity 1934331-1. All parts are EAR99 classified and HTSUS 8536.69.4040 coded.
