Molex 0760558608 Equivalent & Substitute Parts

Part Overview

The Molex 0760558608 is a 240-position backplane connector header with male pins for through-hole PCB mounting. This Impact series connector features a 0.053" (1.35mm) pitch configuration with 15 rows and 16 columns, supporting 80 differential pairs. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Header, Male Pins
• Number of positions: 240
• Mounting type: Through Hole
• Termination method: Press-Fit
• Contact finish: Gold
• Material flammability rating: UL94 V-0
• RoHS compliance: ROHS3 or equivalent

Secondary Considerations:

• Pitch tolerance (0.053" primary; 0.075" alternative acceptable with design verification)
• Operating temperature range
• Voltage rating
• Packaging format

Substitute parts are grouped into two categories:

Category 1 - Direct Molex Equivalents: Parts 0760555608 and 0760559608 maintain identical electrical and mechanical specifications to the main part, differing only in product status (active) and packaging format (tray vs. original packaging).

Category 2 - Cross-Manufacturer Alternatives: TE Connectivity AMP Connectors parts 1934331-1, 1934332-1, 1934333-1, and 1934334-1 provide functional equivalence with modified pitch (0.075" vs. 0.053"), higher voltage rating (250V vs. 30V), and extended operating temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

Parts 0760555608 and 0760559608 are preferred for applications requiring exact electrical and mechanical compatibility with the original 0760558608. Both maintain the 0.053" (1.35mm) pitch, identical operating temperature range, and 30V voltage rating. Selection between these two Molex alternatives depends on packaging requirements and inventory availability. Both are active products with ROHS3 compliance.

For Cross-Manufacturer Substitution (TE Connectivity AMP Connectors):

Parts 1934331-1, 1934332-1, 1934333-1, and 1934334-1 provide functional equivalence with design considerations. The 0.075" (1.90mm) pitch represents a significant geometric change requiring PCB layout verification. These alternatives offer enhanced electrical performance with 250V voltage rating and 0.5A current rating, plus extended operating temperature range (-65°C ~ 90°C). All four TE Connectivity parts are active products with RoHS compliance. Selection among these four variants depends on specific compliance certifications required for the application.

Compliance Considerations:

All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance status. The main part (0760558608) is ROHS3 compliant; substitute parts maintain equivalent or superior compliance levels. Moisture sensitivity level (MSL 1 - Unlimited) is consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can I use parts 0760555608 or 0760559608 as direct replacements for the obsolete 0760558608?

A: Yes. Both Molex parts maintain identical electrical and mechanical specifications including 240 positions, 0.053" pitch, 15×16 configuration, through-hole mounting, and press-fit termination. The primary differences are product status (active vs. obsolete) and packaging format (tray). No design modifications are required.

Q: What is the main difference between the Molex and TE Connectivity substitute options?

A: The Molex alternatives (0760555608, 0760559608) preserve the original 0.053" (1.35mm) pitch. The TE Connectivity parts (1934331-1 through 1934334-1) use a larger 0.075" (1.90mm) pitch, requiring PCB layout verification. TE Connectivity parts offer higher voltage rating (250V vs. 30V) and extended temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C).

Q: Can I use TE Connectivity parts 1934331-1, 1934332-1, 1934333-1, or 1934334-1 as direct drop-in replacements?

A: Not without design verification. While these parts maintain 240 positions and identical row/column configuration, the pitch change from 0.053" to 0.075" requires PCB footprint modification. Mechanical compatibility with existing mating connectors must be confirmed before implementation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part is ROHS3 compliant. All substitute parts maintain RoHS compliance: Molex parts are ROHS3 compliant; TE Connectivity parts are either ROHS3 or RoHS compliant. All meet environmental regulatory requirements.

Q: What packaging formats are available for these substitute parts?

A: Molex direct equivalents (0760555608, 0760559608) are supplied in tray packaging. TE Connectivity alternatives (1934331-1 through 1934334-1) are supplied in tube packaging. Packaging selection may affect procurement lead times and handling requirements.

Q: Which substitute part should I select if I need the closest electrical and mechanical match?

A: Parts 0760555608 or 0760559608 provide exact specification matching with the original 0760558608. Both are active Molex products with identical pitch, position count, and operating parameters. Selection depends on packaging preference and inventory availability.
