Molex 0761656607 144-Position Impact Header Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0761656607 is a 144-position backplane connector header with male pins designed for through-hole PCB mounting. This connector features a 9×16 configuration with 0.053" (1.35mm) pitch and press-fit termination, supporting 48 differential pairs in an Impact series with guide-left orientation.

The main part (0761656607) carries an Obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this connector specification.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0761656607 are identified based on strict electrical and mechanical parameter equivalence within the Impact 76165 series. The substitution criteria are:

• Identical connector type (Header, Male Pins)
• Identical number of positions (144)
• Identical pitch (0.053" / 1.35mm)
• Identical configuration (9 rows × 16 columns)
• Identical mounting type (Through Hole)
• Identical termination method (Press-Fit)
• Identical contact layout (48 Differential Pairs)
• Identical contact finish specification (Gold, 30.0µin)
• Identical operating temperature range (-55°C to +85°C)
• Identical voltage rating (30V)
• Identical material flammability rating (UL94 V-0)
• Identical RoHS compliance status (ROHS3 Compliant)
• Identical MSL rating (MSL 1)

The substitute parts 0761653607 and 0761657607 meet all these criteria and are classified as direct equivalents. Both substitute parts carry Active product status, providing improved supply chain availability compared to the Obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (0761653607 and 0761657607) are direct functional equivalents to the main part 0761656607. Selection between them should be based on the following factors:

Product Status: The main part carries Obsolete status, while both substitutes are Active. For new designs or ongoing production, Active parts provide superior long-term supply chain support and manufacturing continuity.

Compliance & Certifications: All three parts maintain identical compliance profiles: ROHS3 Compliant, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. No compliance trade-offs exist between the main part and substitutes.

Packaging: The main part packaging is not specified, while both substitutes are supplied in Tray packaging. Tray packaging is standard for high-pin-count connectors and facilitates automated assembly processes.

Inventory Availability: Current stock levels are 977 pcs (main part), 716 pcs (0761653607), and 763 pcs (0761657607). Inventory selection depends on immediate procurement requirements and supply chain logistics.

For applications requiring component continuity with the obsolete 0761656607, either 0761653607 or 0761657607 provides full electrical and mechanical compatibility with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 0761653607 and 0761657607 fully compatible with the original 0761656607?

A: Yes. Both substitute parts are electrically and mechanically equivalent. They share identical connector type, position count, pitch, configuration, mounting method, termination type, contact layout, contact finish, operating temperature range, voltage rating, flammability rating, and RoHS compliance status. Direct substitution is possible without PCB redesign or assembly process modification.

Q: What is the difference between the two substitute parts?

A: The substitute parts 0761653607 and 0761657607 are functionally identical. Both carry Active product status and Tray packaging. The only practical difference is current inventory availability (716 pcs vs. 763 pcs) and potential lead time variations based on supplier stock levels.

Q: Why is the main part marked as Obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The Active status of the substitute parts indicates that Molex continues to support this connector specification through alternative part numbers within the same Impact 76165 series.

Q: Does packaging type affect electrical performance?

A: No. Packaging (Tray vs. unspecified) affects logistics, storage, and automated handling but does not alter electrical or mechanical performance. The connector specifications remain identical regardless of packaging format.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts maintain identical compliance certifications: ROHS3 Compliant, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. No compliance trade-offs or restrictions apply to substitution.

Q: Can I use these connectors in high-speed differential signaling applications?

A: The connector supports 48 differential pairs as specified in the contact layout. Electrical performance for high-speed applications depends on PCB design, trace routing, impedance control, and system-level signal integrity considerations beyond the connector specification itself.

Q: What is the moisture sensitivity level (MSL 1) and what does it mean for storage?

A: MSL 1 (Unlimited) indicates the connector has no moisture sensitivity restrictions. These parts can be stored at standard ambient conditions without requiring dry-pack packaging or baking procedures prior to assembly.
