Molex 0760557607 240-Position Backplane Connector Header: Equivalent & Substitute Parts

Part Overview

The Molex 0760557607 is a 240-position backplane connector header designed for through-hole PCB mounting. This Impact series connector features male pins with press-fit termination, configured as 15 rows by 16 columns with 0.053" (1.35mm) pitch spacing. The connector is actively manufactured and widely used in high-density interconnect applications requiring reliable signal distribution across multiple differential pairs.

Substitute parts become necessary when the original Molex Impact series component reaches end-of-life status, when supply constraints occur, or when design requirements call for alternative electrical or mechanical specifications within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

The three substitute parts listed—TE Connectivity 1934331-1, 1934332-1, and 1934334-1—are qualified alternatives within the backplane connector category. These substitutes maintain functional equivalence through the following critical parameters:

• 240-position connector configuration
• 15 rows × 16 columns matrix layout
• Male pin header design
• Through-hole PCB mounting
• Press-fit termination method
• Gold contact finish
• UL94 V-0 flammability rating
• MSL 1 (Unlimited) moisture sensitivity

The substitute parts differ in pitch specification (0.075" / 1.90mm versus 0.053" / 1.35mm), voltage rating (250V versus 30V), current rating (0.5A versus unspecified), and operating temperature range (-65°C to 90°C versus -55°C to 85°C). These differences represent design trade-offs between the Molex Impact series and the TE Connectivity Z-PACK TinMan series.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and comply with RoHS and ECCN EAR99 classifications. The Molex 0760557607 and the three TE Connectivity alternatives are suitable for applications requiring 240-position through-hole backplane connectivity with press-fit termination and gold-plated contacts.

Selection between the Molex Impact series and TE Connectivity Z-PACK TinMan series depends on PCB layout constraints and electrical requirements. The Molex part operates at 30V with 0.053" pitch, supporting higher-density layouts. The TE Connectivity alternatives operate at 250V with 0.075" pitch and include a specified 0.5A current rating, providing greater electrical headroom for power distribution applications.

All parts carry MSL 1 (Unlimited) moisture sensitivity, eliminating moisture-related handling restrictions. The extended operating temperature range of the TE Connectivity parts (-65°C to 90°C) provides additional thermal margin compared to the Molex specification (-55°C to 85°C).

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1934331-1, 1934332-1, and 1934334-1 be used interchangeably with Molex 0760557607?

A: These parts are functionally equivalent in terms of position count, row/column configuration, mounting method, and termination type. However, the pitch difference (0.075" versus 0.053") requires PCB redesign. The TE Connectivity parts occupy a larger footprint and cannot be directly substituted without layout modification.

Q: What is the significance of the pitch difference between the Molex and TE Connectivity parts?

A: Pitch determines the physical spacing between connector pins. The Molex 0760557607 uses 0.053" (1.35mm) pitch for higher density, while the TE Connectivity alternatives use 0.075" (1.90mm) pitch. This difference affects PCB trace routing, via placement, and overall board real estate. Direct pin-for-pin substitution is not possible without PCB redesign.

Q: Are there compliance differences between these parts?

A: All parts comply with RoHS and carry EAR99 ECCN classification. The Molex part specifies ROHS3 compliance, while the TE Connectivity 1934332-1 and 1934334-1 specify general RoHS compliance. The TE Connectivity 1934331-1 specifies ROHS3 compliance. All parts carry UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity.

Q: What are the differences in electrical ratings?

A: The Molex 0760557607 is rated for 30V with unspecified current. The TE Connectivity alternatives are rated for 250V at 0.5A per contact. The higher voltage rating of the TE Connectivity parts provides greater electrical margin for applications requiring higher voltage distribution.

Q: Do these parts require different handling or storage procedures?

A: All parts carry MSL 1 (Unlimited) moisture sensitivity level, meaning they do not require special moisture-controlled storage or handling procedures. Standard ESD precautions apply to all parts.

Q: What packaging formats are available?

A: The Molex 0760557607 is supplied in Tray packaging. The TE Connectivity alternatives (1934331-1, 1934332-1, 1934334-1) are supplied in Tube packaging. Packaging format may affect inventory management and automated assembly processes.
